The technical field to which the invention relates.
This invention relates to a device for freezing, transporting and thawing fluid, primarily sterile liquids and slurries for chemical, biotechnological, pharmaceutical and food industry, according to claim 1 of the formula of the invention and the method of defrosting of such liquids according to claim 9 claims.
Description of the prior art,
In the production of chemical, pharmaceutical and biotechnological industry, but also in the food industry is the increasing globalization of production processes has led to the increasing requirements of logistics for storage and delivery of semi-finished products, for example, from cellular structures for sequential processing and selection of the target product. In order to meet this problem again and again, you need to freeze smaller or large quantities of liquid intermediate and/or final products and transported frozen to the party. For this purpose, the prior art various devices which contain the tank with the device freezing-thawing, which can freeze batches from a few to several hundred liters.
For example, from U.S. patent 552706 known device with a vertically arranged cylindrical vessel with a funnel-shaped bottom with a Central outlet opening. Wall and the bottom of the tank is made double-walled, and in the process of freezing through the cooling substance. To ensure gentle and uniform freezing in the tank has plenty of cooling elements. Cooling elements are hollow cylinders, the diameter and length of which is so coordinated with each other that they are arranged concentrically with respect to each other and pass through the inner space of the tank from the upper region, which is set to the maximum level, almost to the bottom. Distance refrigerated items from the bottom of the tank and their distance relative to each other are the same everywhere. Through located on the upper side of the pipelines that connect all cooling elements can be a supply and discharge of the cooling medium on which is located on the upper side of the cover only inlet and outlet piping. Accordingly, to defrost through the cooling elements is sent to a warm environment and after complete condensation of the tank contents tank is emptied through a Central bottom outlet in the region of the lowest point of the tank. Since, according to the U.S. patent 5524706 cooling elements occupy a large part of the volume of the tank and have a very large surface, freezing and resmor the lid can occur quickly and in a sparing mode, without the use of additional stages of the process. However, for economic reasons it is desirable significant reduction in refrigeration items to save costs and to increase the useful volume of the tank.
The applicant has developed a device freezing and transportation, for which the process of freezing in their temporal and local characteristics quantitatively determined by the temperature and phase transitions in the tank. The device under the trademark FreezeContainer® depicted in figures 1A and 1b and scalable up to 300 liters has a number of advantages. The phone weighs 10% less compared with other known devices. Design of refrigeration elements provides a time-homogeneous phase transition by volume of the reservoir, which, on the other hand, ensures a short time process. In addition to these advantages the overall design of the device is sufficiently volatile so that the device FreezeContainer® can be integrated into complex production processes and thus meets the requirements of the pharmaceutical industry on operational and process safety.
To defrost warm environment is again directed through the vessel wall, the bottom of the reservoir and the cooling coils. A process p is morgiane preferably enhanced by a slight shaking of the tank.
A closed reservoir is filled from the top by fixed in the lid of the inlet pipe fluid environments, primarily sterile liquids and slurries for chemical, biotechnological, pharmaceutical and food industries, hereinafter called the product. The inlet pipe is just above the Central outlet at the lowest point of the bottom so that the product after complete thawing can be selected through the drain hole in the bottom or through the supply pipe.
In order to further increase the already high degree of functional scope and adaptability to the process, preferably the availability of pumping product when thawed that existing equipment is not possible.
On this basis, the objective of this invention is to provide a device for freezing, transporting and thawing fluid, primarily sterile liquids and slurries for chemical, biotechnological, pharmaceutical and food industries, which avoids the disadvantages of known devices and allows the highest degree of operational capabilities. The next task of the invention is to provide a device and method which is faster and gentler than ever before to thaw frozen is already installed, while facilitating mixing the thawed substrate.
This problem is solved by the device according to claim 1 and the method according to claim 9 claims, which include heated intake tube, which pre-thawed and therefore makes it possible to transfer, that is, the selection and return thawed and preferably pre-heated product during the entire thawing process. The disadvantages of this method are eliminated, and achieves a more rapid defrost.
Proposed in the invention is a device for freezing, transporting and thawing fluid, primarily sterile liquids, solutions and suspensions for chemical, biotechnological, pharmaceutical and food industries, equipped with a reservoir that includes a cover wall and a bottom and at least one heat exchanger element which is in contact with the loaded in the reservoir fluid environments with the possibility of cooling or heating. When the intake tube is in contact with at least one heat exchange element on at least one part of its length, and on the tank in the region above the maximum height of fill, preferably in the cover, is a bypass so that during defrost is liquefied, allocated through the intake pipe from the lowest point of the tank and pre-heat the th fluid has the ability to transfer a bypass pipe on top of the still frozen fluid medium.
Thus, the proposed invention the device has at least one intake pipe, which is in thermal contact with a heat exchange elements on at least a section of its length, which preferably extends approximately from the lowest point of the tank to the maximum level. The maximum level is the level to which the reservoir is filled subject to freezing the product, which can be controlled thawed. First of all, it is determined by the location of the heat exchange elements, taking into account the volumetric expansion of the heat exchange elements due to changes in density. The following variants of the invention it is located between the upper edge of the reservoir and the upper parts of the heat exchange elements. Preferably, the intake tube is in direct contact with at least one heat exchange element and is passively heated. When thawing the liquefied product can be extracted through at least one heated intake pipe, which, in turn, is preferably from above through the interior of the tank and terminates above the lowest point of the bottom. In comparison with the known devices with a supply pipe, loc is defined freely in the inner space of the tank and thereby freely in the frozen product, heated the intake tube has the advantage that the frozen product within the intake pipe very quickly thawed and selection of unfrozen liquid product is only blocked in the initial phase of the process of defrosting. In addition, the selection of unfrozen product when passing through the intake pipe carefully heated so that it is located substantially above the freezing point temperature may be submitted preferably on top of the still frozen integral part of the product and speed up the thawing process. For this purpose, in the preferred form of carrying out the invention on the inside of the lid of the tank are the bypass pipeline.
Heating the thawed product in the intake pipe during the selection has a significant advantage compared to the selection at the final hole in the bottom. If known from U.S. patent 5524706 device thawed product is withdrawn through the bottom outlet, the product has a temperature only slightly above freezing. If this cold fluid is pumped through located in the lid of the filling nozzle on the frozen product, it hardly leads to the acceleration of the process of defrosting. According to this invention is now pumped product is served preheated is and frozen parts that speeds up the thawing process. In addition, the diversion of the thawed product through an outlet in the bottom of technically disadvantageous.
Another advantage of the new device is that the path that must be liquid product when the pump outside the tank, can be kept very short, as there is no need to send it from the drain holes in the bottom for loading into the reservoir cap. Thus, on the one hand, you can avoid unwanted pipelines on the outer side of the tank, and on the other hand, with the new device can be top convenient to carry out the filling and emptying, as well as transfer, as all the connecting elements can be located in the lid or at least in the upper region of the tank.
In private preferred embodiments of the invention the intake tube can provide a communication connection between the first lower hole in the lowest point inside the tank and a second opening positioned on the top side on the tank or on the lid.
Further, the intake tube with the link may be in thermal contact with a heat exchange element about from the lowest point of the tank to at least the maximum height of the fill.
In the preferred performance of the heat exchanger element R is t in itself a cooling coil, and the intake tube at the site of its length laid coaxially at the level of the cooling coil and is with him in thermal contact, preferably in direct contact.
In this case, the link of the intake tube in the area, which stretches roughly from the maximum level to the lowest point of the tank, can be laid vertically and coaxially in the Central area of the cooling coil and along the longitudinal axis. When this link fence pipe may form the inner wall having the shape of a hollow cylinder the Central section of the cooling coil so that the intake tube and the cooling coils in this area integrally connected to each other according to the principle "pipe in pipe".
Heat exchanger element may include a double bottom and double wall, and the intake tube at the site of its length may be held inside or outside of the bottom and sides and can be located in thermal contact, preferably in direct contact.
The bypass conduit can pass through the cover and end in at least one, preferably two discharge openings above the maximum level, which are arranged in such a way that the pumped fluid is directed to the upper parts of the heat exchange elements, preferably cooling Zeevi is a, and reduced pricing.
Proposed in the invention is a method of thawing frozen fluid, primarily sterile liquids, solutions and suspensions for chemical, biotechnological, pharmaceutical and food industries, is carried out in the above-described device and differs in that warm environment is directed through at least one heat exchanger element and defrost frozen the fluid in the intake pipe, which is in thermal contact with at least one heat exchange element, and then thawed fluid from the lowest point inside the tank through the intake pipe can be selected and pre-heated before it is pumped through a bypass pipe on top of the still in the reservoir the fluid.

Detailed description of preferred forms of implementation
Figure 1A shows a longitudinal section belonging to the applicant tank for freezing and thawing. As already stated above, this tank is known from the prior art under the name FreezeContainer. Tank In a tightly closed lid BD. Together with the lower bottom BB and side wall BS BD cover sets internal is prostranstvo I tank, where is the cooling coils KS. As shown in figa, the cooling coil is in communicating connection with the internal double wall tank on a stand-alone cooling pipe KL. Cooling medium that is supplied via the respective inlet pipeline AM to the double wall of the tank BW, after passing through the tank wall BW and the bottom of the BB goes through the cooling pipe KL in the cooling coils KS. For professionals is obvious that freezing and thawing we are talking about technically reversible processes that can be implemented using depicted on the figure 1 device and similar type devices according to the invention. Therefore, for simplicity in the following description of the essential elements of the devices described primarily as suitable for cooling. If in future we are talking about the cooling elements, the cooling coil and similar items, it is clear that these heat exchange elements are suitable not only for transmission of cold remedies or protection during the freezing process, but also for transmission and interaction with warm liquid during defrost.
The geometry of the cooling coil KS is defined by many passing vertically plots EV, each of which is connected with each other through the om top or accordingly, the lower horizontal sections of ENfor optimal temporal and local characteristics of the temperature and phase transitions in the interior space 1 of the tank. While the upper and lower horizontal sections of ENare, respectively, approximately in the same plane, located at the center in the tank vertical part EZextends further down to almost the lowest point of the tank. This ensures early thawing directly above the Central drain hole in the bottom of the BB reservoir area. It has established itself as particularly beneficial, as in the area of the bottom outlet of the placement of the heat exchange elements in the bottom of the tank is very difficult. Facing the BD cover the upper horizontal links of EBUTare in the area directly below the maximum level FNtank, respectively, they determine the maximum height of the fill. The vertical links in the beginning and at the end of the cooling coil pass through the cover BD tank and connected, respectively, with the inlet ZM coolant and the cooling pipe KL, and thus indirectly with the release of AM.
The tank for freezing and thawing according to figure 1 with the serious volume of 300 litres has an essentially cylindrical shape with a Central longitudinal axis L. Known from the prior art tanks usually come in sizes from a few to several hundred liters.
On fig.1b shows the tank In freezing and thawing according figa in the side view, rotated 90°, which is visible supply pipe ZR, which forms a signaling connection from the top side of the cover to almost the lowest point in the internal space of the first tank Century. the Supply pipe ZR with the upper vertical segment ZV tubes held between two vertical sections of EVat almost uniform distance from them. Above the lower horizontal section of EHUshe bent and beveled area ZS goes to the lowest point T of the tank, where it ends in the hole ZO.
The tank preferably in the closed state, i.e. with attached lid, filled with product to be freeze through the supply pipe ZR. After reaching the desired level corresponding to the supply valve on the upper end side of the inlet pipe is closed and starts the cooling process, during which the cold medium is directed through the cooling circuit, which, along with cooling coil, the tank wall and bottom of the reservoir comprises at least not depicted in the drawing, the pump, and also not depicted refrigeration unit or tank with cool what they means, until the product in the inner space of the tank will not be kontrolowane frozen and will not be achieved desired negative temperature for storage or transportation. In this state, the product inside the supply pipe ZR is frozen and the pipe is blocked. To defrost through the cooling circuit is routed warm environment and to speed up defrosting tank mounted on the installation plate P, slightly shaken. Deeply lowered Central vertical section EZ ensures that the area above the Central outlet opening thaws out relatively quickly. Although the supply pipe ZR ends precisely in this area, the thawed product can be exhausted only when thawed inner channel inlet pipe. As has briefly been outlined above, this is achieved only when thawed almost the entire product. Through the bottom Central outlet And through which a drain pipe connected with AL connecting the exhaust element of AA on the end side of the mounting plate P may, in the defrost is relatively early to merge the thawed product. But as known in the tank there is no possibility of returning this liquid product, it cannot be pumped. In addition, polucen the th through the bottom Central outlet While the product is still very cold and when you return in the inner space of the tank hardly conducive to defrost.
Figure 2 shows the preferred implementation of the device 1 for freezing-thawing according to the invention, which is based on the above tank for freezing-thawing.
A longitudinal section of figure 2 shows that it is now in the tank 10 to freezing-thawing is the intake tube 60. Preferably, the intake tube at its first end on the lid 20 is a valve 64, which includes the connecting element 65 for supply and the connecting element 66 for selecting the appropriate valves 67, 68 and check valve 69. From the valve 64 of the intake tube 60 with the first vertical line is laid down, passes through the cover 20 and still passes over the lower edge 21 of the cover at a slight incline through a radial link 52 to the center of the almost cylindrical inner space 11 of the tank. Upon reaching the longitudinal axis L of the tank intake pipe 60 again bends and stretches with the link 63 (second Central vertical link) along the Central axis L to about the lowest point of the inner space of the tank and terminates there in the hole a. The intake tube 60 is along the longitudinal axis L concentrically surrounded by a vertical link 51 refrigerating element. The remaining component parts of the refrigeration element according to the nfiguration follow essentially established itself inflection, which is known from the above FreezeContainer applicant's cooling coils. The wall 40 and the bottom 30 of the tank 10 also again constructed in a known manner with double walls and contribute to heat transfer. Through new technical features according to the invention is achieved in that the plot intake tube 60, which lies between the bottom 30 of the tank and a maximum height of fill FMAXis in optimal contact with the freely flowing in the inner space of the tank of the heat exchange element, i.e. with cooling coil 50.
If thawing is required pumping, using a described location of the intake tube and cooling coil and/or other heat exchange elements is ensured that the inner channel intake tube very soon after the start of the skip warm medium through the cooling circuit thaws. The thawed product, which again is collected at the lowest point of the tank, may be taken up at an early time during the defrosting through intake pipe 60. As a second extremely favorable effect is added that is still very cold liquefied product is heated during transport through the Central part 63, as this link is washed by the warm environment.
Preferably, the link 63 intake tube 60 forms vnutrenniy the wall of the link 51 of the cooling coil, which has the shape of a hollow cylinder so that the intake tube and the cooling coil are integrally connected to each other in the form of a "pipe-in-pipe and intake pipe integrated in direct thermal area of influence of the cooling element. The lower portion 63' of the link 63 intake tube is not surrounded to the next vertical part 51 of the cooling coil, and a few inches protrudes from it. The lower portion 63' may be very simply adjusted according to the size of the tank 10 by means of circumcision in size so that it is ensured that the lower hole of the intake tube and warm (i.e. thawing and transfer) is still at the desired radius is preferably 5 mm, but at least 1 mm from the tank bottom or above the bottom outlet hole in the bottom. Existing devices can, for example, to retrofit the combination according to the invention of refrigeration element and an intake tube as it is depicted in figure 2b with under cover component parts, and the length of the intake tube can accurately and easily adjusted on site. Thus, it is possible to minimize the loss of product that cannot be pumped out of the tank. In a preferred embodiment of the invention, as shown in figure 2b, the intake tube has an internal diameter which 18,1 mm and a wall thickness of 1.6 mm The Central part 51 of the cooling coil, for example, is useful for a tank with a volume of 300 liters diameter 42,4 mm, the remaining parts of the cooling coil, respectively 21,3 mm, The free cross section of flow is maintained approximately the same at all levels. Separate sections of the intake tube and the cooling coil is preferably made of austenitic steel, for example 4435/316L and alloy Hastelloy and welded to each other manually by way of welding tungsten inert gas. In order to effectively create connection "pipe" and to ensure easy cleaning, proved to be the most favorable to close the upper entrance level 63 intake tube 60 in the Central vertical link 51 of the cooling coil 50 and the corresponding bottom outlet with an annular stub 53. The environment of the heat exchanger is supplied and/or removed from the Central vertical element 51 of the cooling coil 50 through the upper horizontal link 56 and the lower inclined link 57, each of which side ends in the vertical link 51 in the vicinity of its respective ends.
The intake tube and the cooling coils can be made of two parts and can be inserted into each other so that the wall of the intake tube comes in to the tact with the inner wall of the Central link 51. For tanks that are used repeatedly, features one-piece (single items) form of implementation, as the cleaning goes much faster.
Next, with reference to figure 2 describes the thawing process and selection of the thawed product. The authors believe that the tank 10 to freezing-thawing filled frozen product to the maximum level FMAX. If water is directed through the cooling coils, the substrate S in the area affected by the WB of the heat exchange elements, i.e. in the area of influence of the cooling coil and double-walled tanks and double bottom tank, preferably slowly thaws in a sparing mode.
On figa shown that deep omitted integral part of the cooling coil, namely, the lower inclined radial link 57 cooling coil and a lower area of the Central element 51 provides that the thawing of the product at the lowest point of the tank and around it thaws out very early. According to the invention the inner channel of the Central section 63 of the suction tube 60 is released from ice one of the first areas in the inner space of the tank. The thawed product, which is collected at the lowest point of the tank 10, can thus be drawn from the tank 10 at a very early stage of the process is oriane. The liquefied product is heated during transport through the Central section of the intake tube to the top and open the valves 69 and 68 is fed through a coupling element 66 of valve 64 for selection to not depicted in the figures, the unit transporting a fluid medium, preferably a conveyor or pump. From this block preheated product is fed back into the tank 10 through the bypass pipe 70, which is shown in figure 5 with its constituent parts on the upper side of the cover and on the underside of the cover. On the side view according fig.5b on the lid 20 is not depicted, the means of transportation (e.g., a pump) and the pipelines that are over the cap are connected to each other connecting element 66 of valve 64 intake tube and the connecting element 71 for filing. When you open the valve 72 of the heated product is returned back to the tank through the bypass pipe 70, which is the vertical link 73 passes through the cover 20 and is connected to angled elbow 74. End discharge opening 75 of the tribe 74 is connected to the side with a vertical link cooling coil above the level of determining the maximum height of fill FMAX. The pre-heated product when pumping is served on top of the frozen surface of the product and thus contributes to the process ramarajan who I am. Placing the discharge aperture 75 of the tribe of 74 due to the fact that the pumped product is directed to the vertical level of the cooling coil. Thus, when the pumping of the product may significantly reduce foaming.
The combination of selection and pre-heating the thawed product by immersion element 60 according to the invention with a direct return on the bypass pipe 70 at an early point in time, in which most of the product in the inner space 11 of the tank 10 is still frozen, allowing quick and gentle thawing.
Instead gasket intake tube as described above, through the Central link of the cooling coil, in the following preferred form of the invention, which is shown in figure 4, it is an alternative. In this case, the intake tube 60' passes through the link 51' of the cooling coil 50', which takes place in the upper pane in parallel between the wall 40 of the tank and the longitudinal axis L and in the lower pane tilted toward the low point of the tank 10. Thanks to this design, again provided that the intake tube on the entire distance from the lowest point of the tank to the maximum level concentrically surrounded respectively adjusted by the link 51' cooling the ZMA is Vika 50'.
In the following embodiments of the invention the intake tube covers the cooling coils so that when design "pipe in pipe" intake pipe is outside and is cooled or heated element cooling coil lying inside. Regarding thermal conductivity of these implementation options are less preferred. The same applies to variants of implementation, in which the intake tube and interacting with it link cooling coil is made in the form adjacent to each other halves of the pipe, while there is also degraded the dynamics of the flow.
Figure 3 shows the following option exercise, in which the intake tube 80 is connected not with cooling coil KS, and double wall tank 40' and double bottom 30' of the tank. In order not to complicate the cleaning of the internal space of the tank, the intake tube 80 is fully recessed in the wall 40' and the bottom 30' and ends at the bottom of the hole 81 in the area of the lowest point of the tank 10', preferably in the Central exhaust hole 31' in the bottom 30'. In the upper wall 40' tank intake pipe sticking out through the side of the connecting element 82 forms a communication connection with the inner space of the tank. In order to not negatively affect the flow of the heat exchanger walls in the e tank and the bottom, the intake pipe can be laid on the outer sides of the double wall 40' tank and double bottom 30', i.e. essentially in the insulating housing 12.
The idea of the invention to connect the intake pipe with a heat exchange elements is not limited to have been specifically described and depicted in the figures, elements, and can be transferred to many other elements. Items for freezing-thawing placed in the form of a spiral heat exchangers can also be connected to the intake pipe for the selection and pre-heating of the product such as plate and star-shaped heat exchange elements.
Decisive is that between the heat exchange element and at least a section of the intake pipe, which lies in the area of the frozen product, which is approximately the lowest point of the tank to the maximum level, respectively, in a frozen state filled with them, there is thermal contact. Direct contact between the immersion element and the heat exchange element according to the above implementation of the "pipe-in-pipe and pipe-in-the-wall is not mandatory, but preferential.
The technical idea of the invention can be transferred to disposable devices that are very popular because of their distinctive efficiency by reducing supplies the species in the area of CIP and sterilization equipment (CIP/SIP). Such "one-off" devices, the entire device in their real disposable versions may be made of suitable synthetic materials. In other embodiments of the invention thermally passive components, i.e. essentially the bottom, lid, tank and the intake tube made of synthetic material in the form of "disposable", and heat exchange elements are made of metal and after using disconnected from the tank, cleaned and used again.
Figure 5 shows the spray pipe 90, which when cleaning/CIP tank is used in conjunction with its built-in elements. The cleaning solution is supplied through the coupling element 91, which in the depicted example implementation is sprayed through the spray head attached to the end of the two spray pipes. As the cooling coils and the intake tube is free from occupying a large area of stabilizers, thread, built-in elements and the guide plates, it is reduced to a minimum not only be cleansed surface, but also difficult to spray. It also helps to ensure that cleaning, CIP washing and sterilization equipment CIP/SIP carried out extremely simply and efficiently.
In the following embodiment of the invention is abora pipe, which size and placement essentially corresponds to the supply pipe ZR in the device according fig.1b is electrically or inductively heated. For the electric version, preferably in the wall of the intake tube away from the product and the environment are heating wire, a heating coil or other heating elements. For the inductive variant of the intake tube by at least the important parts are made preferably of a ferromagnetic material. As for the electrical heating of the intake pipe of the voltage source and the inductive heating of respectively strong magnetic source, both these options are only used under certain conditions.
