Description

The invention relates to a disposable container for storing and for quick cooking of food according to the preamble of claim 1.

The invention is intended for use in the food industry and can be used as a disposable container for storing and quickly cooking mainly frozen foods and foods (such as seafood, vegetables, chicken, etc.). The disposable container can be used in fast food service as well as in the organization of fast and on-board feeding.

From the patent RF 2277786 (20.06.2006) a device for the execution of the method for steam vacuum treatment of food is known. It contains a chamber for its stowage and means for defrosting the food with thin steam.

This known technical solution mainly relates to means for defrosting food (fish, seafood, meat) and can be used in canned fish production. The peculiarity of the known technical solution is that the defrosting of the food takes place by the product is heated with steam. The steam is generated at the residual pressure. The temperature corresponds to the residual pressure. During heating, the residual pressure is gradually increased in the range of 9.2 to 23.7 mm Hg with a stop at each stage. The intermediate temperature corresponds to the pressure in this stage. The hold time is determined depending on the temperature balance between the product surface and the steam.

The product to be defrosted z. B. at a temperature of -23 ° C in the vacuum chamber (defroster) used. Thereafter, the chamber is hermetically sealed, supplied with room temperature water and connected to a running vacuum pump. Once a residual pressure of 9.2 mm Hg is reached in the vacuum chamber, a radiator is turned on to raise the temperature and maintain it at 30 ° C. The steam produced by boiling water expands. The temperature drops to a temperature corresponding to the respective equilibrium residual pressure, d. H. up to 10 ° C. At this temperature, the vapor settles on the surface of the frozen product and releases its latent precipitation heat as soon as the product surface reaches the temperature of about 10 ° C. Balancing the steam and surface temperature indicates that the first and subsequent heating stages are completed, depending on the residual pressure build-up.

The disadvantage of this known technical solution is a relatively longer defrosting time of the food. In addition, it is not possible to use the device for the subsequent cooking of food in a fast food system.

By the RU 2383289 (20.03.2009) is a device for carrying out the process for the preservation and in particular for the heating of food known. The device has a container which serves as a transport and commercial packaging. The container has a draw hole which is designed to ensure that the food is warmed up by an external light source.

The peculiarity of this known technical solution is that the food in the wet state by means of microwaves are heated in a container. The container serves as a transport and commercial packaging until it produces superheated steam and exits through the draw hole to the outside. In order to partially compensate for the decrease in pressure in the container, an oxygen-free gas is injected into the container by means of a hollow needle (cannula) after warming up. This makes it possible to store the food in the container in a moist state for a long time.

The shortcoming of this known technical solution is a limited scope for keeping the foodstuffs moist by heating them with superheated steam using microwaves.

The prior art disposable containers for storing and for quick Garmachen sublimated foods in the form of pasta, especially containers of the trademark ROLLTON for individual courts "noodles in homemade beef broth", known (see, for example, products of the company ROLLTON OOO MAREVEN FOOD CENTRAL " Brand RF, MO, Serpukhovskiy R-, d. Ivanovskoye, Severnoye Sch., 31. TU 9149-00-93676776. WWW.ROLLTON.RU ).

The peculiarity of this known disposable container is that it has a working compartment for a single court. The working compartment consists of relatively thick-walled polystyrene. The working compartment has a thin, transparent PE sealing cover at the top to allow sublimated food to be placed in the container at normal pressure and temperature. The disposable container is designed so that the individual dishes can even be warmed up by filling the working compartment with 300 ml of cooking water and allowing the product to stand until it is ready for use.

The deficiency of this known technical solution is that it is difficult or impossible to use the known one-way container for cooking frozen food by filling the working compartment with cooking water without the product contained in the disposable container, e.g. B. in a microwave oven, is also warmed up.

The closest to the invention technical solution is this disposable container for storage and for quick Garmachen of food. The disposable container has a working compartment for holding frozen food at normal pressure and in such a way that it is possible to cook the food by heating with an external heat source (see products of the company "SADIA", sales representative in the RF "SADIA ROSSIYA "123317, Moscow, ul. Testovskaya, 17. WWW.SADIAPROMO.RU ).

The peculiarity of this known disposable container "Sadia" for storing and quickly making a frozen single dish "lasagne" four cheeses "or other similar dishes is that it has a working compartment and a sealing lid, which consist of a relatively thin laminate board. The disposable container is used to hold frozen food at atmospheric pressure, so that it is possible to even heat after the seal in the oven or in the microwave oven. In addition, the work compartment is housed in an additional environmentally friendly cardboard packaging from FSC C 014015.

The deficiency of this known technical solution is a limited scope of use of the disposable container "Sadia" for storing and quick cooking of frozen food, because for heating mainly a furnace or microwave radiation of a microwave oven is used.

It is an object of the invention to provide a relatively cheap and easy-to-use disposable container for storing and quick cooking of a wide variety of frozen foods (vegetables, seafood, chicken, etc.) that can be used using available sources of heat, this one-way container suitable for the organization of a system for fast food and on-board feeding.

Description of the operation of the proposed one-way container for storing and quick serving of frozen food.

A serving of 200 to 300 g of the mentioned food prepared in a known manner for quick cooking is placed in the working compartment 1 of the disposable container ( 1 ) at normal pressure for storage. Thereafter, the said amount of steam generating liquid 9 (Water) in the process compartment 3 filled. The edges of the disposable container form-fitting to a lock 11 fixed. This is the flat removable lid 2 to the upper edge of the side panel 7 of the soil 10 of the process compartment 8th mechanically or thermally connected. Thereafter, the stocked disposable container in the freezer compartment of a refrigerator (not shown) for freezing the said portion of the food and the steam generating liquid 9 at a temperature of -15 to -40 ° C with subsequent storage of the food-filled disposable container in the freezer at a temperature of about -5 to -20 ° C set.

To use the said portion of food, z. B. on-board power in the aircraft, the disposable container with the respective portion of the frozen food and water is taken from the refrigerator and set to the on-gas or electric stove (not shown). If the disposable container is completely airtight, then z. B. the surface of the removable lid 2 pierced to make a 2 to 5 mm ² opening. This opening serves to drain the superfluous water vapor. The floor 10 of the process compartment 8th of the disposable container and its content is heated in the course of 3-12 min., Depending on the composition and the amount of frozen product and the intensity of the heat supply. In this case, the steam generated during said time flows out of the process compartment 8th through the holes 5 in the perforated plate 4 to different parts of the food pieces 3 , This ensures their defrosting and cooking. After the expiry of the prescribed time according to the preparation instructions for this type of product, the disposable container is removed from the oven. The removable lid 2 is opened, and the disposable container with the food is open for consumption.

The modern way of life requires the use of accessible and easy-to-use disposable containers for storing and / or quickly cooking food to maximize the time for the consumer. The food may have a liquid, mushy (semi-solid), solid or frozen state. The trend towards the development and use of disposable packaging, utensils and containers for ready-to-serve juices, sour milk products, sublimated vegetables, meat and seafood dates back to the 1960's. The disposable packaging for use in the food industry and in the disposable containers for storing and quick cooking food is mainly made of plastic, eg. As polystyrene or polypropylene, strong paper, laminate board, Styrofoam and partially or entirely made of aluminum foil. To the disposable containers, including the proposed disposable containers, many important requirements. These include in particular the gas and moisture sealing to prevent the ingress of foreign gases, flavorings and microorganisms, sufficient mechanical strength and durability in use, easy disposal options and a pleasant appearance.

The aluminum foil used in the proposed disposable container and the plastics used are multipurpose materials that are best suited for the manufacture of disposable containers. The proposed partially or completely made of thin or stronger aluminum foil disposable container protects the food just like the usual dishes. This one-way container is extremely inexpensive, lightweight, compact, it needs no cleaning and is ready to dispose of immediately. The food in partially or completely made of plastic and aluminum foil made disposable containers can be defrosted, heated and steamed. That is, it is in some ways possible to imitate a process of steam cooking, etc. on the household gas or electric stove, in the traditional Russian oven, or on open wood fire.

The food in the proposed disposable container can be hygienically and conveniently prepared especially in the fast food and on-board feeding, under field conditions and with minimal effort and time. The proposed completely or partially made of metal foil disposable container ensures the preservation of important organoleptic, flavor and taste properties of prepared food, without additional intervention in the cooking process, sure.

The main advantages of the proposed disposable container are low material and manufacturing costs, high procedural, functional, aesthetic, environmentally friendly and hygienic properties. Such disposable containers are suitable for use in many types of ovens, such. As ovens, convection ovens, grill ovens, etc., well suited. Strong temperature differences usually exert no influence on the construction and strength of the disposable container. The food can be conveniently prepared in a disposable container, frozen, transported and served.

The high thermal conductivity of the components of the disposable container made of aluminum foil helps to accelerate both the freezing and the steam cooking of the food. It also makes it possible, in particular, to restore the natural taste properties and the moisture content of the food faster and better than, for. B. when heated with cooking water or in a microwave oven is the case. The proposed disposable containers are used to store food in all production and distribution stages. They act as an excellent hygienic barrier against the development of bacteria in the working space of the disposable container.

The disposable containers made of aluminum foil and plastics for storing and quick food making are a safe and environmentally friendly barrier to protect the food against harmful external influences. They are also characterized by a minimal negative environmental impact, because the plastics and aluminum are chemically passive and processable. They are maintenance-free, do not require cleaning and are easily recycled after use.

The current increasing use of disposable containers, including those made of aluminum foil, is related to the advantages mentioned and to the fact that they present a beautiful package for various foods and at the same time a crockery for storing, transporting, heating and serving the food.

The texture state (consistency) of most cooked with steam in the proposed disposable container food is considerably better (softer, more delicate) than the textual state of z. B. conventionally cooked and fried foods. This prolongs the shelf life of frozen foods. The disposable containers for steam cooking of the food are ideal for the products "home-to-go". The achieved degree of tightness of the proposed disposable container prevents the ingress of moisture and grease from the outside. That is why the food is kept fresh, tasty and rich in aroma even when stored for extended periods in the frozen state. The plastic and aluminum foil disposable container heats the food with steam more carefully and gently while preserving the original structure and taste. Since all (steam-treated) dishes prepared in such disposable containers need no fat (oil, butter) and are closer in texture to the cooked foods, anything that is prepared in these disposable containers can be recommended for diet meals, including those for baby food.

The proposed design of the disposable containers for storing and quick food making makes it possible to develop a wide range of cost-effective, user-friendly multi-purpose containers with the possibility of continuous storage and quick steaming of frozen foods (vegetables, seafood, chicken etc.) ensure rapid catering and on-board feeding when heated by means of common sources of heat, including gas and electric stoves.
