The invention relates to utensils for cooking.

The world is de 100oC or fats when 120-180oC. In the famous dishes when cooking in water consumes a lot of heat energy, in the finished food from natural products lost vitamins and other beneficial ingredients in addition, the food moving hazards contained in chlorinated tap water (see Small B. N., Blucher B., Ivanov, L. A., Small, S. C. "Green technology cooking in cast ware", journal Foundry, M., 1997, 2, S. 25 and 26).

Famous dishes for thermal treatment of food products, the capacity of which is made of bimetal stainless steel - heat-conducting material (see Der Konstrukteur 1976, N3, S. 12. Verbundmetall-neue Anwendungsmoglichkeiten). A disadvantage of the known dishes is the high consumption of heat conducting material.

Famous dishes for thermal processing, containing a capacitor, a layer of heat-conducting metal, located under the bottom of the tank, the casing of stainless steel, adjacent to the layer of heat-conducting metal, and the cover, the contact surface of the cover is made in the form of flanges (see EP 0222699, 20.05.87).

In the famous dishes is impossible to carry out heat treatment natural products at temperatures below 100oC and without water for cooking ecologicas and others). Also impossible heat treatment of food products in the container to obtain the alcohol-containing liquid, such as vodka, cooked at home. In industrial conditions used for this apparatus, comprising a container with a pump, a column with partitions, glasses, reflux condenser, refrigerator, measuring device and spiropent (see "Agricultural encyclopedia". Edited Benediktov I. A. and others, so 4. - M, GIL, 1955, S. 577). The basis for the preparation of vodka industrial way is raw alcohol. If it is prepared from zernotorgovelna raw materials, it contains 0.02-0.15% of poisonous methyl alcohol. When using as raw material molasses (departure at sugar refining) or pure sugar methyl alcohol in alcohol-raw is missing (see "the Technology of alcohol". Edited Yarovenko C. L. - M.: Kolos, 1996, S. 320 and 321). Due to the preparation and sale of counterfeit vodka on the basis of technical (methyl) alcohol in Russia die each year up to 40 thousand people. At home to make vodka (alcohol) use a homemade steam apparatus consisting of a vessel with a cover, coil, connected to the lid, the device for cooling the coil by flowing water and sportapro is the Asel, up to 0.03% of aldehydes and up to 500 mg/l esters. These hazards remain in vodka in the absence of treatment, for example, a known filter materials or biologically active coagulators out of steam apparatus (see Pokhlebkin Century History of vodka. - M. : inter-Verso, 1991, S. 227-231).

Closest to the technical nature of the claimed device is selected as the closest analogue of cookware for heat treatment of food products containing metal vessel, the layer of heat-conducting metal, located under the bottom of the tank, made of alloy, the coefficient of thermal conductivity which is 2-7 times higher than the conductivity of the material of the bottom of the tank, the thickness of the bottom of the tank is 5-20% of the thickness of the layer of heat-conducting metal, the cover contact surface of the cover and the vessel made in the form of flanges, casing from stainless steel, adjacent to the layer of conductive metal, removable mesh liner can install the latest in the tank (see patent 2143833 issued in Russia 10.01.2000, Small VP). Cookware allows for thermal processing of food products with steam temperature below 100oC formed on the bottom of the dish and cooling Ensenaste heat transfer at the contact boundary between the conductive metal and stainless steel falls during operation of dishes due to the low corrosion resistance of heat-conducting material layer. The ratio of the coefficients of teploprovodnosti conductive material layer and the capacitance of the well-known dishes, which is 2-7 times higher than thermal conductivity of the material of the bottom, not enough to quickly heat the heat storage plate. Lots of dishes can increase substantially because of the high specific gravity of heat-conducting layer. For example, iron-carbon alloys have a coefficient of thermal conductivity is 3-4 times higher than stainless steel, but their share is several times higher than that of aluminum alloys. Therefore, when the thickness of the conductive layer 5 times greater than the thickness of the bottom of the tank, the mass of the dish increases significantly, and it becomes malodorous during operation. Many aluminum alloys having a low specific weight, for example, type AL9 not have high corrosion resistance. Low corrosion resistance of the alloy causes the formation of a thick maloteploprovodnoj layer of oxides in the bimetal aluminum alloy - stainless steel". This layer is hard and brittle, so prone to destruction from overheating or from shock loads on the bottom. In this case, the bimetallic bottom layers, which violates the technological process of heat treatment products, uvelichenie is holding a fluid by heat treatment of food products placed in the tank.

These drawbacks limit the technological capabilities of dishes with cooked food.

The problem is solved that by changing the design is expanding the technological capabilities of dishes with cooked food.

The technical result from the use of the invention is to stabilize and accelerate the accumulation and heat transfer of thermal energy from the heat source through thermal storage the bottom of the dish with the conductive layer, as well as in the implementation process for thermal treatment of food products for the preparation of alcohol-containing liquid in the container.

The goal is solved by the fact that cookware for heat treatment of food products containing tank made of stainless steel, a layer of heat-conducting metal, located under the bottom of the tank, made of alloy, the coefficient of thermal conductivity higher than thermal conductivity of the material of the container, the thickness of the layer of conductive metal is greater than the thickness of the bottom of the tank, replaceable liners in contact with the container, the cover contact surface of the cover and emcore, according to the invention the layer of conductive metal is made of corrosion-resistant conductive alloy, the coefficient of thermal conductivity which 8-14 times higher thermal conductivity material capacity with one of the removable liners made with the possibility of installation on the vessel, equipped with a lateral wall, as well as additional capacity and partitions connected by a tube placed inside a removable liner, the ends of which are made curved and in contact with the flanges of the lid and container.

The execution layer of heat-conducting metal from corrosion-resistant conductive alloy, the coefficient of thermal conductivity which 8-14 times higher thermal conductivity material capacity, reduces warm-up time, the heat storage plate ware and stabilizes the operation of the ware during the heat treatment of food products.

The execution of one of the removable liners with the possibility of installing it on the vessel, equipped with a lateral wall, as well as additional capacity and partitions connected by a tube placed inside a removable liner, the ends of which are made curved and in contact with the flanges of the cover and the vessel, obespechit of the invention is illustrated by drawings.

In Fig. 1 shows utensils (cut), equipped with a replaceable liner in contact with the bottom part of the vessel; Fig.2), the same is equipped with a replaceable liner in contact with the upper part of the vessel and the lid.

Utensils for thermal treatment of food products includes a container 1 made of stainless steel, a layer of heat-conducting corrosion resistant metal 2, the casing 3 of the stainless steel adjacent to the layer of conductive corrosion-resistant metal 2, exchangeable 4 (Fig.1) and 5 (Fig.2), the cover 7. Cover 7 and the container 1 is equipped with curved flanges 8 and 9, and also handles 10 and 11. The layer of conductive corrosion-resistant metal 2 has a coefficient of thermal conductivity in the 8-14 times higher than thermal conductivity of stainless steel, which is made from the container 1. As materials for the conductive layer of corrosion-resistant metal 2 in the container of Fig. 1 and 2 is used chemically pure aluminum brand of HELL 1. Its coefficient of thermal conductivity at 20oC is equal to 0.52 cal/schrad). The stainless chrome-Nickel steel AISI 304, which is made all the metal elements of the dish of Fig. 1 and 2, the coefficient of thermal conductivity at 20oC is equal to 0,039 cal/schrad). Thus, coefficie capacity 1, 13.4 times. The thickness of the steel parts of the bottom and walls of the container 1 and the lid 7 and the cover 3, the same and equal to 1 mm, the thickness of the corrosion-resistant conductive metal 2 is equal to 9 mm In Fig.1 shows the Assembly of utensils for its work with removable liner 4 by heat treatment of solid natural food without water and fat. Removable liner 4 contains holes 6 spaced across the lateral surface and the bottom. The upper part of the removable liner 4 is open to the possibility of inserting and extraction products thereof. Removable liner 4 is in contact with the container 1 along the inner part of her bottom. In Fig.2 shows a variant of the Assembly of utensils for its work with removable liner 5 by heat treatment of food products for cooking in a pot of alcohol-containing liquid. Removable liner 5 is placed on the end of the tank 1 and contacts the bottom end with a flange 9 of the tank 1 and the upper end with a flange 8 of the cover 7. Removable liner 5 includes a continuous side wall 12 and the additional capacity is 13, which is formed by the convex part of the septum 14 and part of the inner surface of the side wall 12. On the convex side of the partition 14 is a through hole 15 and a mounting opening in the top end. The partition 19 overlaps the end face of the flange 17 and contains a hole for fastening the lower end of the tube 16.

Consider the process of cooking in a pot, is shown in Fig.1. This cookware allows you to cook various natural products (vegetables, meat, fish and others). Cooking in a pot dishes such as cabbage and meat wieners, carried out in the following sequence. Fresh cabbage white & redhead cleaned, washed and shredded. Sausages are placed on shredded cabbage. On the container by the handle 11 open the cover 7, is removed from vessel 1 removable liner 4. Portions of products for heat treatment, especially their training, the duration of the periods and stages of heat treatment, etc. are specified in the technical instructions for the preparation of natural products without water and fat" (further Instructions) that came with the dishes. Products are then placed in a removable liner 4, place it in the container 1 and cover it with a lid 7. This shaped flanges 8 and 9 on the lid 7 and the container 1 is tightly contact each other, providing a sufficiently high integrity dishes. Then the dishes in the collection take the handles 10 and put on a thermal energy source, such as a gas stove with regulator heating. Prior those who according to the instructions in the Instruction, and is controlled by the user of the dishes on time. After a period of heating of the heat storage of the bottom of the tank 1 heat treatment continue in the position set at level "Minimal heating. The duration of the heat treatment in this mode is determined by the Instruction. During thermal processing of products is the circulation of the steam inside the ware between the heated heat-retaining bottom of the container 1 and the lid 7 in contact with the environment. The source of steam is "product liquid (capillary water and juice), which in small amounts is allocated in the form of drops from the cut of natural products, housed in a removable liner 4. "Grocery liquid" flows of products through the holes 6 in the removable liner 4, the inside of the container 1. Since the inner surface of thermal storage of the bottom of the tank 1 is continuously heated by the transfer of thermal energy from gas stoves through the casing 3, a layer of corrosion-resistant heat-conductive metal 2 into the vessel 1, on the bottom of the evaporation product fluid". The resulting vapor with a temperature below 100oC passes through the holes 6 in the removable liner 4 and heats the food. Due to the use of the realised stable and rapid transfer of thermal energy from the heat source into the vessel 1 through the elimination of chemical and thermal conditions for the formation of thick maloteploprovodnoj layer of oxides of aluminum and iron on the contact boundary between the aluminum - stainless steel. Elimination maloteploprovodnoj oxide layer in the bottom of thermal storage tank 1 and a high coefficient of thermal conductivity corrosion-resistant conductive layer 2, which is 13.4 times higher than thermal conductivity of the material of the container 1, allows to reduce the time of heating of the heat storage plate to the working temperature. After contact of steam with products in removable liner 4 and heating, the steam is cooled. Therefore in contact with the inner surface of the cover 7 is the condensation of the steam in the form of droplets, consisting of product fluid." The inner surface of the cover 7 has a conical shape, so drops of the condensed product of the fluid flow to the interior of the curved flange 8 of the cover 7 and then fall on the heated thermal storage the bottom of the tank 1. This process is repeated several times during the heat treatment of products that are cooked at temperatures below 100oC. After completion of the period of cooking mode minimum heat according to the Instructions of the regulator its intensity is switched to the "Off" position, and the final stage of heat treatment is continued only at the expense of thermal energy accumulated cor is provodnogo layer 2 into the atmosphere, protects the casing 3 stainless steel adjacent to the specified layer. The duration of the final stage of heat treatment at the expense of thermal energy accumulated corrosion-resistant conductive layer 2, is determined by the Instruction. After completion of the dishes for the handle 10 is removed from the gas stove. Then the handle 11 open the cover 7 and is removed from the container 1 removable liner 4 placed in it products. Warm food placed in the plate. Before its use, it is added to vegetable oil or other seasoning (sauce or mayonnaise, or ketchup and other ) in accordance with the Instructions and recommendations tailored to the individual taste of the user. Food cooked in a pot of steel grade 304, without the use of standard chlorinated tap drinking water and environmentally friendly products with minimum (background) chemicals is environmentally friendly. For example, the number controlled by standard chemical substances in drinking water in the CIS contains a priority list of 13 controlled hazards, while in water bodies near industrial centers, the number of hazards is a list of 500 titles (see "Environmental aspects of examination of inventions" edited and Chelyabinsk regions radioactive hazards, for example in 2000, exceeded the permissible sanitary norms 1000 times. Use gentle heat treatment with a temperature below 100oC allows you to save in the finished food, the bulk of the useful components (vitamins, pectins, proteins, minerals, the original structure of the intracellular fluid and other) contained in natural source products, so this food is especially useful for prophylaxis and treatment of diseases of the stomach, kidneys, heart and joints. At the conclusion of the U.S. Federal control over the quality of the food and drug administration standard chrome-Nickel stainless steel, grade 304 absolutely safe as material for cookware because of the absence of corrosion in the food environment and discharge of chromium or Nickel stainless steel of the specified brand in the finished food. The presence in the construction of utensils thermal storage bottoms and tight sealing of the flanges, as well as cooking with minimal heating of the bottom and no water can save up to 70% of thermal energy compared with traditional thermal processing of foods in a metal container with a thin bottom and leaking cap.

Consider the process of making alcohol-containing liquid in the container (Fig. the seat reservation is being prepared. For example, a certain portion of sugar is dissolved in high-quality drinking water and incubated with the addition of yeast for some time. The thus prepared liquid food is poured into the container 1. Then into the hole 15 in the wall 14 fill in water, after which the removable liner 5 install the lower flange 17 on the flange 9 of the tank 1. After this removable liner 5 is closed by a cover 7, which tightly contacts the flange 8 with the upper flange 18 of the removable liner 5. The dishes Assembly mounted on a gas stove with regulator heat level. The technology of food preparation for heat treatment with the aim of obtaining alcohol-containing liquid, the periods and the duration of heat treatment of the liquid, the amount of materials for the purification of alcohol-based liquids from existing hazards are listed in the technical guidelines for the preparation of alcohol-containing liquid" (next instruction), attached to the dishes. The regulator of the gas on the stove put in the position of "Medium heat", the duration of which is determined by the Instruction. After a period of operation in this mode, the knob on the stove is switched to the position "Minimum heating. During heating of the bottom of the tank 1, the liquid Razah is therefore its evaporation from the tank 1 is greatly increased, than the evaporation of water. The presence of the heat storage plate in the tank 1 stabilizes the transfer of heat energy from the heat source to the liquid filled in the container 1. Alcohol vapor through the opening in the lower end of the tube 16 to pass through it and are cooled by heat transfer through the outer surface of the tube 16 to the water filling the enclosed space inside removable liner 5 between the walls 19 and 14. Then alcohol vapor through the upper open end of the tube 16 extend in an enclosed space in the upper part of the removable liner 5, formed part of its side wall 12 and the cover 7. Due to heat transfer through the side wall 12 and the outer side surface of the removable liner 5 is the secondary cooling of the vapors of alcohol. Then "cold steam" rises to the inner surface of the cover 7 having a temperature close to the room, and condenses on the lid 7 in the form of drops. Excessive temperatures produced during condensation and transfer of alcohol from vapor to liquid state, is removed by heat transfer through the cover 7 and its outer surface into the surrounding air environment. Drops of alcohol slide down the inner conical surface of the cover 7 in the direction towards the inner part of the flange 8, posted the second container 13. From the liquid in the tank 1 together with the alcohol evaporates and some water. Water as well as alcohol, cooled, condenses on the inner surface of the cover 7, so the condensed liquid called alcohol.

After a certain period of time according to the manual control of heating put in the "Off" position. The final period of heat treatment is due to the heat accumulated corrosion-resistant conductive layer 2, and the hot liquid in the tank 1. The enthalpy of corrosion-resistant conductive layer 2 is kept from scattering in the atmosphere through the casing 3 made of stainless steel with a thermal conductivity of 13.4 times lower than thermal conductivity of the material of the corrosion-resistant conductive layer 2. After completion of the final period of heat treatment, as defined in the regulations, the dishes apart. For this purpose, the handle 11 to remove a cover 7, then take out the removable liner 5. Tilt removable liner 5 of the additional capacity 13 alcohol-containing liquid is poured into the container to its storage and purification from impurities. Then removable liner 5 is turned 180oand through at alcohol-containing liquid contains methyl alcohol, has a strength of 40 degrees. From other impurities (fusel oils, aldehydes and esters) this fluid is additionally purified using known filter materials and coagulants (see Pokhlebkin Century Century History of vodka. - M. : inter-Verso, 1991, S. 227-231) according to the Instruction and outside of cookware.

Quality homemade vodka not only saves human health through exposure to the culture of cooking and moderate consumption of pure product, but also prevents the possibility of poisoning fatalities, occurring at random buying and drinking adulterated vodka made unfair by the manufacturer, for example, containing methyl alcohol.
