The present invention relates to a device for obtaining protein-lipid emulsion of oil seeds and can be used in the food industry, for example, to obtain a protein-lipid emulsions of kernels of cedar nuts.

The known device for obtaining protein-lipid emulsions from oil seeds contain structural elements for implementation of basic operations, such as mixing of raw materials and solvents, grinding of raw materials, dissolving soluble in the solution of the raw material components, separation of liquid product from the solid residue. Among such devices include, for example, the installation for the production of soy milk [1].

A characteristic feature of the devices of protein-lipid emulsions from oil seeds, due to the requirement to increase the efficiency of the process is intensive mixing; the combination of processes of dissolution and grinding; the implementation of the processes of mixing, crushing, dissolving, education suspension and separation of liquid and solid phases in a single device. The most frequently used means of solving this problem is the use of the devices performing the mixing, grinding, dissolution and the formation of a suspension in one device, which generally run in a container, inside which the rotating knives, or apparatus with rotary grinding elements.

Among such devices include, for example, a device for soy milk [3]. The last device according to their design characteristics most closely matches the present invention and taken as a prototype.

The device prototype includes a housing, a motor drive, capacity, grinder, heater, filter, cap and valve pressure reduction. The capacity is fixed in the housing. In the lower part of the body, isolated from the tank, is the engine. Inside the tank is a chopper connected to the drive spindle and is made in the form of a knife. The filter is located parallel to the base of the tank and is capable of moving along the walls of the vessel. Above the filter is a cover, the walls of which rely on the filter, forming an air chamber. The lid has a valve pressure reduction. To the bottom of the tank with external parties summed up the heater.

The operation of the prototype is in periodic mode, which has three phases: loading raw material; mixing, grinding, dissolution, formation of the suspension, and separating the liquid product from the solid residue; unloading of the final products. In the load capacity soy seeds and drinking water with the engine switched off and the heater and removed the cover and the filter. Then insert the filter and the lid, the level of liquid loaded into the vessel below the level of the filter in the tank, and result in the engine and heater. The rotation axis of the actuator is transferred to the shredder. Rotating knives carry out the mixing and grinding of soybean seeds. Simultaneously heating the powdered mixture, dissolving the protein-lipid complex and the formation of a homogeneous suspension of the solution and the insoluble residue of soybean seeds.

In the process of heating the crushed mixture produced water vapor, which, rising upward through the filter and accumulated in the air chamber. Excess water vapor pushes the air from the air chamber, opening the valve in the lid. At this point, turn off the heater and the engine. Water vapor is cooled and condensed. In the air chamber is reduced pressure and the valve is closed. The atmospheric pressure presses the cover and the filter to the crushed seeds. Due to the difference of pressure in the air chamber and the vessel with the slurry liquid phase is forced through the pores of the filter in the air chamber and separates the solid and liquid phases of the slurry. The liquid phase is soy milk through the hole in the cover for the valve is removed from the apparatus. The solid residue of crushed beans - Okara after removing the cover and the filter is unloaded from the tank.. the Device is a prototype performs operations of mixing, grinding, dissolution, formation of the suspension, and separating the liquid phase from the solid residue in a single device. However, the device has drawbacks: periodic mode of the device; insufficiently intensive mixing is carried out only at the expense of the rotating blades; coarse grinding of soybean seeds, which determines the duration of the processes of dissolution and extraction of protein-lipid complex of the channels then seeds. To accelerate these processes, the powdered mixture is heated in the heater, resulting in unnecessary energy costs and the complexity of the design.

The technical task to be solved by the invention is to increase the efficiency of the device for obtaining protein-lipid emulsions from oil seeds.

The essence of the invention lies in the fact that in the known device for soy milk containing chopper, filter, tank, drive, cover and an opening for drainage of liquid product under this proposal, the filter is made in the form of a rotating funnel, serving over capacity, connected to the axle drive through the Central hole in the base and divides the device into the chamber of the collection of protein-lipid emulsion with a hole for removal of protein-lipid emulsion in the side surface of the vessel and the working chamber with the tube feed, mixer and grinder, consisting of two disks with rough or profiled surface located one above the other with a gap, tapering from the center to the periphery, and a rotating knife, the knife is connected to the drive spindle, the lower disk is rigidly connected to the bottom of the filter and the upper disk is rigidly connected to the supply pipe raw material, is lowered through the Central hole in the lid into the working chamber, the inside of the tube feed is located stirrer, coaxially connected to the drive, and the edge of the filter is at the level of openings for removal of the solid residue, and the cover is fixed on the container.

Thanks to the introduction of a new set of features ensures the continuity of the process of obtaining protein-lipid emulsion of oil seeds, accelerated technological process, decrease the energy costs of the implementation of the basic operations of the process. This increases the efficiency of the device and its performance.

In the particular case of implementation of the invention the device is made with a variable gap between the disks, which allows to achieve the required degree of grinding of raw materials having different geometrical dimensions and physical-chemical composition. Thus, optimum conditions of grinding, dissolution and filtration, ensuring continuity of the process with maximum recovery of the protein-lipid complex.

In another particular case, the implementation of the present invention to intensify the operation of mixing and prevent congestion raw material mixer is made in the form of a rod bent.

In another particular case, the implementation of the present invention to improve the reliability of preventing the penetration of solid residue in the protein-lipid emulsion of the device is made with a pocket between the walls of the container and the lid in the place of their connection and the top edge of the filter pad with Board, bent down at an angle not more than 90° and lowered into the pocket without touching it, while the angle between the base of the pocket and the container wall is not more than 90°.

The essence of the invention is illustrated in the drawing, which shows the device in General.

Device for obtaining protein-lipid emulsions from oilseeds has a reservoir 1, separated by rotating the filter 2 into two chambers: the upper 3 working and the bottom 4 for protein-lipid emulsion. The filter 2 is funnel-shaped with side filter surface, the upper edge of which has no pores and protrudes from the container wall, not touching her. Inside the filter is located chopper 5. Chopper 5 consists of a rotating knife and two disks, while the knife is in the center tapering from the center to the periphery of the gap formed by the inner surfaces of the disks. The lower disk is fixed on the base of the filter 2. The upper disk is mounted at the end of the feed tube raw material 8, which is connected with the Central hole in the cover 9, the opposite end. Inside the tube feed 8 is a stirrer 7, coaxially connected to the drive.

In the wall of the cover 9 is made a hole 10 for removal of the solid residue in the bottom part of the vessel wall 1 has a hole 11 for removal of protein-lipid emulsion. Grinding the disc surface is made of rough material or shaping metal, the remaining parts of the device are made of metal.

The work of the proposed device for obtaining protein-lipid emulsions from oil seeds is carried out as follows.

When the device starts to operate the actuator 6. The rotation axis of the actuator 6 is transferred to the filter 2, the associated lower disc grinder 5, the mixer 7 and the knife grinder 5, located in the working chamber 3 of the container 1. Continuously flowing in the pipe feed 8 oil seeds and solvent are mixed by the mixer 7 and fed into the gap of the chopper 5, where the first stage is a coarse crushing of oilseeds in the environment of the solvent with a knife. Coarsely ground mixture under the action of centrifugal forces moving through the gap from the center to the periphery and additionally crushed. As the narrowing of the gap increases the degree of crushing oilseeds to the size of the particles, which results in rapid dissolution of soluble substances and the formation of a homogeneous suspension. Through the gap suspension enters the filter 2, rotating at a speed that provides the centrifugal forces, the simultaneous separation of the liquid phase and the solid residue and the automatic removal of the solid residue from the filter 2 through its upper edge, and then out of the apparatus through the side opening 10 in the cover 9. Liquid product (protein-lipid emulsion) from the filter 2 flows through the pores in the chamber 4 of the tank 1, and then through a side opening 11 at the bottom of the container 1 is removed from the apparatus.

The angular speed at which to rotate the actuator 6 and, respectively, connected the mixer 7, the rotating elements of the chopper 5 and the filter 2, ensures the continuity of processes: uniform receipt of raw material to the shredder 5; grinding, dissolution, formation of the suspension; separating the liquid phase from the solid residue and the automatic removal of products from the apparatus.

Exercise chopping in two stages, first rough by means of rotating knives, and then using the grinding discs with rough or major surface, allows to achieve a desired amount of the dispersion, in which there is virtually instantaneous dissolution. This is because when chopping by abrasion using disks is the destruction of the channels then oilseeds, not soluble in the solvent, and, therefore, increases the contact surface of the soluble substances in the channel pore, and solvent. At the same time due to the friction of the rubbing surfaces is heated powdered mixture, which also accelerates the process of dissolution and the formation of the suspension.

Rigid fastening of the lower disc grinder 5 based filter 2 allows simultaneous rotation and thereby revokerole supply of the suspension to the filter surface and the removal of the solid residue from the bottom of the filter 2 up to its edge. This prevents the clogging of the filter and decrease the rate of filtration.

In the particular case of implementation of the invention is the obtaining of protein-lipid emulsion of oil seeds produced during the installation of the regulator gap between the discs of the chopper 5. Thus the value of the gap between the disks shredder is installed before switching on the device. This creates optimal conditions for grinding, dissolving and filtering based on the structure, chemical composition and the geometrical sizes of oilseeds.

In the particular case of implementation of the invention is the obtaining of protein-lipid emulsion of oil seeds is done when installing the mixer 7 in the form of a rod bent. The result is a large degree of homogeneity in the distribution of oilseeds in the solvent and prevents the possibility of congestion of raw materials.

In the particular case of implementation of the invention is the obtaining of protein-lipid emulsion of oil seeds is running in the device pocket between the walls of the container 1 and the cover 9 in place of their connection and the upper edge of the funnel filter 2 in the form of a pad with the Board, bent down and lowered into the pocket without touching it. This Board bent down at an angle not more than 90° and the angle between the base of the pocket and the container wall 1 is not more than 90°. In the result, this prevents the solid residue from the filter 2 into the chamber 4 for protein-lipid emulsion in the tank 1.
