Description

The invention relates to the food industry, in particular to the preparation of food products stored in a frozen state and subjected to cooking before use, for example, dumplings, using a microwave oven, and also to devices for such cooking.

A known method of preparing food products from dough with filling, including the preparation of dough, preparing the filling, molding the product, packaging in special packaging, storage, followed by heat treatment before use (see RU 2251271). In accordance with this method, after molding, the product is dried with microwave radiation in the temperature range of 20-120 ° C to a moisture content of 6-12%, and before drying, the product is steamed to a temperature of at least 70 ° C inside the product.

Using this method leads to a decrease in the taste of the product.

A known method of preparing food products from dough with filling, for example dumplings, including dough preparation, preparing the filling, molding the product, deep-freezing the product, packaging in special packaging, storage at low temperatures, followed by heat treatment before use. The heat treatment of the frozen product extracted from the packaging consists of placing it in a container with boiling salted water with spices and boiling it before cooking (see http://fb.ru/article/206502/vidyi-upakovok-dlya-pelmeney, http: // www. povarenok.ru/recipes/show/68496/, etc.).

As packaging can be used hermetically sealed or tied, for example, with a ribbon, plastic bags (see http://www.povarenok.ru/recipes/show768496/), containers, closed with a film (see), cardboard boxes (see https : //www.perkamkopa.lv/en/product/8580/Pelmeni-BUJUMS-sdelannie-v-Latvii/selectType, http://km-meat.ru/index.php?lang=rus&id=36, etc.) .

A known method of preparing food products from dough with filling, including preparing dough, preparing the filling, molding the product, packaging in a container, freezing, storage and subsequent heat treatment before use, the heat treatment is carried out by cooking stored in the container frozen food in a microwave oven in a layer of liquid added to the container (see RU 73317). In this case, the product is placed in a closed lower chamber of the external tray with a perforated lid placed inside it, which is blocked from above by a removable overlapping element. The perforated lid divides the internal volume of the specified tray into two chambers, the lower one for accommodating the specified semi-finished products and the upper open chamber with high walls for trapping boiling water and foam formed during cooking of these food semi-finished products. Before cooking, water is poured into the lower chamber, a removable overlapping element, made in the form of a Velcro sheet sticker, is removed from the specified roof, thereby freeing the lid openings. This method is selected as a prototype of the claimed method.

The disadvantage of the prototype method is the need to remove the overlapping element before installing the tray in the microwave oven. The user may forget to remove this element, made in the form of a sticker-Velcro. In this case, there is a danger of destruction of the tray, pouring product with water into the furnace, pollution of the internal surface of the furnace and failure of the furnace itself, as well as a threat to the health of the user: it may be scalded.

As a prototype for the inventive device, a device is selected in the form of a container for storing and preparing frozen food semi-finished products according to the prototype method, which includes an external tray with a perforated lid placed inside it, which is closed on top with a removable overlapping element, while the specified perforated lid divides the internal volume of the specified tray into two chambers, the lower closed chamber to accommodate the specified semi-finished products and the upper open chamber with high walls for trapping boil s water and foam produced during cooking of said semifinished food (see. RU 73317). The external tray and cover are made of polypropylene, paper or laminated cardboard.

The disadvantages of the prototype device include the complexity of its design: the presence of two cameras, one of which, with the product, is first closed, then partially opens, the presence of a cover and an additional overlapping element.

The objective of the present invention is to improve safety and simplify the heat treatment using a microwave oven.

The objective of the present invention is to simplify the design of the device for implementing the method.

The first of these problems is solved due to the fact that in the method of preparing food products from dough with filling, frozen and packaged in containers with a lid, by heat treatment in a microwave oven with preliminary addition of water to the container, according to the invention, the volume of product placed in the container is less more than twice the volume of the container, the lid is removed from the container before cooking, and water with a temperature of 90-100 ° C is poured to the mark, and the product with water occupies 45-55% of the volume of the container.

After packaging the product, the container with a lid can be packed in a protective shrink film.

To solve the second of these problems, in a device for preparing frozen and packaged food products from dough with filling using a microwave oven, made in the form of a container of heat-resistant material, equipped with a lid, according to the invention, the container is made in the form of a glass, the volume of which is calculated depending on a predetermined amount of product, and is equipped with a level mark of the water poured before preparation, and the lid is removable.

The container may be made of laminated cardboard.

The container may be made in the form of expanding upward glass.

The cover may be made of heat-resistant or non-heat-resistant material.

The container may be provided with a removable protective shrink film.

The studies showed the possibility of high-quality cooking of frozen product, in particular, dumplings or dumplings, without the undesirable effects of vapors on the inner surface of the microwave oven, provided that the water level above the product layer and the remaining unfilled part of the container is exceeded. In this case, the risk of deformation or rupture of the container is completely eliminated, that is, the necessary level of safety of the cooking process is ensured. The process of cooking prefabricated and frozen foods placed in a container with a removable lid includes simple operations that are accessible even to the student: removing the protective shrink film, removing the lid, filling the container with frozen product with boiling water with a temperature of 90-100 ° C to the mark on the container wall and placing the container in a microwave oven. The operating modes of the microwave oven and cooking time can be indicated on the container.

Thus, the claimed complex invention (method and device for its implementation) ensures the achievement of the following technical result: simplification of the technology for the preparation of frozen products with filling, as well as an increase in the safety of the cooking process using a microwave oven. In addition, the maximum simplification of the design of the container for storing and cooking frozen food is provided.

Conducted patent studies have confirmed the conformity of the proposed method and the container for implementing the method of patentability criteria "novelty" and "inventive step". They also meet the criterion of “industrial applicability”.

The essence of the proposed integrated technical solution is illustrated by drawings, on which (Fig. 1) is a schematic illustration of a container. In FIG. 2 shows a photograph of the appearance of the container.

The process of making food products from dough with filling (dumplings, dumplings, etc.) usually involves preparing dough, preparing the filling, molding the product. Food products obtained in this way or purchased from other manufacturers are frozen and packaged in special containers. The volume of the container is calculated on a certain mass or volume of the food product. In this case, the product should occupy less than half the volume of the container. This ratio of volumes provides the necessary economic parameters for the storage and transportation of containers with the product.

It is more convenient to pack the product into containers after a shock freezing, but you can also pack a product that has just been prepared and slightly frozen, and then deep freeze.

Prepared containers with the product are closed with an easily removable lid and packaged in shrink film, which ensures the required level of tightness, prevents evaporation of the liquid entering the product and protects the container from damage during storage, transportation and sale.

Product containers are stored at low temperatures, including when delivered to retail outlets. The consumer purchases a container packed in shrink film, on which the mass of the product is indicated. In the future, the container can be stored in a home refrigerator. If it is necessary to prepare the product, the consumer removes the protective shrink film and lid from the container with the frozen product, pours the specified amount of boiling water (90-100 ° С) into the container to the mark on the container wall, pours out salt and possibly spices from the attached portion bag. At the same time, the volume of the product, together with the water poured to the mark on the container, is 0.45-0.55 of the total volume of the container, which allows high-quality preparation of the product in a microwave oven.

Then the open container is placed in a microwave oven for cooking. Cooking is carried out in the usual way. Cooking modes, including cooking time, the consumer sets himself in accordance with the instructions presented on the container. During operation of the microwave oven, boiling water in the container does not have any harmful effects on the microwave oven. The process corresponds to traditional cooking processes in microwave ovens. The calculated volumes of the container, the frozen product and the water added to the container before cooking ensure the safe preparation of a quality product.

Cutlery, in particular a fork, may be included with the container.

Cooking time is reduced to 5-8 minutes with a maximum microwave capacity of 800 kW.

The container is made in the form of a glass 1 expanding upwards from a heat-resistant material, for example, from laminated cardboard, which withstands the boiling point of water and meets all the requirements of GOST 12301-2006, as well as TP TS 005/2011 “Technical Regulation of the Customs Union“ On Packaging Safety ”(see . Appendix to the application). However, you can use other heat-resistant materials that withstand the effects of this temperature and meet safety requirements.

The container volume is pre-calculated for a certain amount of product. The most preferred dimensions of the container for dumplings weighing 200 g: bottom diameter 10 cm, top diameter 13 cm, height 9.5 cm. The water level mark is at a height of 5 cm from the bottom of the glass.

The volume of a glass is 800 ml, the product (dumplings) occupies a volume of 350 ml, 300 ml of water is added.

Compliance with water volume requirements and preparation recommendations helps prevent water splashing.

The container in the form of a glass 1 is equipped with a removable lid 2. The removable lid 2 can be made of laminated cardboard, as well as the glass itself. But it can be made of a less heat-resistant material, which is more economical, because before cooking, the lid 2 is removed from the glass 1 and it does not affect boiling water.

The glass 1 after placing the frozen product in it is closed with a lid 2 and packaged in shrink film (not shown).

On the side surface of the glass 1, a mark 3 is applied, which determines the level of water poured before cooking.

Case Study

Preparing the dough: took 1 kg of premium baked flour, 1.5 fresh chicken eggs (60 g), added 4 g of salt, 400 g of water and 40 g of vegetable oil, knead the dough. To prepare the filling, they took: 500 g of beef, 300 g of pork, 100 g of bacon and 100 g of fresh onion, added fresh cream of 20% fat, salt, pepper. Formed dumplings and subjected them to shock freezing. All received products are easily separated from each other and have a neat, pleasant appearance. Dumplings are Packed in cardboard cups in portions of 200 g. The glass is closed with a lid and packaged in a protective shrink film.

To prepare dumplings, open the package from the shrink film, remove the lid, pour salt from the portion bag attached to the container and pour boiling water to the level indicated on the outside of the cardboard cup.

After that, they are cooked in a microwave oven with a maximum power of 5-7 minutes, without closing the lid. The water level in the prepared product is calculated in such a way as to prevent spraying and transfusion of the hot broth over the edge of the glass and is equal to approximately half the volume. When the product is ready, the user must carefully, taking precautions, remove the glass from the microwave. After cooking, the broth to taste is drained or left and consumed with dumplings.
