Description

The present invention relates to the field of devices designed for heating and cooking hermetically packed semi-finished products and maintaining their set temperature before serving to the consumer (catering customer).

Well-known devices used, among other things, for heating and cooking semi-finished products, are household and industrial microwave ovens. They are distinguished by ease of operation, wide functionality, as well as the speed of cooking or heating food.

The disadvantages of microwave ovens are:

- increased energy consumption, since a sufficiently powerful microwave generator is required to quickly heat up a dish, which, in turn, requires a large amount of electricity to operate at full capacity. So the power consumption of one professional microwave oven can be from 1 kW to 3 kW (https://restoran-service.ru/catalog/pechi_svch/pech_mikrovolnovaya_menumaster_moc5241/);

- low performance. Despite the high reheating speed, only one dish can be reheated in a microwave oven per cycle. Accordingly, the throughput of a single furnace is low. This is especially true at catering points during the peak millet season.

- to heat up and cook a semi-finished product in a microwave oven, it is necessary to break the tightness of its packaging before heating, because during intensive heating, the air inside the package expands quickly, and the moisture contained in the dish turns into steam. These processes significantly increase the pressure inside the food package, which can lead to the destruction of the package and the release of product from it. In addition, intensive release of moisture from the product during cooking can lead to a deterioration in the consumer properties of the dish.

The closest in technical essence and the achieved result to the claimed invention are the well-known devices for storing ready-made food products in a heated form - food warmers (in public catering - food warmers), the essence of which is that the gastronomy container installed in them with a cooked food product is heated according to the principle water bath or using other heating elements (gas burners or electric heating elements). If the temperature is maintained according to the principle of a steam bath, the food warmers have a heated water tank equipped with a water supply pipe and a drain pipe with a tap at the outlet (https://apachlab.ru/articles/marmit-vidy-osobennosti-konstruktsii-preimushchestva-oborudovaniya /).

The technical objective of the present invention is to create a compact device for heating and cooking semi-finished products with a food warmer function, which will provide:

- heating and cooking semi-finished products according to a given individual program, without the use of microwave radiation;

- heating and cooking semi-finished products without violating the tightness of the package, that is, with the preservation of all consumer properties of the food product;

- automatic transition of the device for heating and cooking semi-finished products with a food warmer function to the mode of maintaining the set temperature of the semi-finished product after the completion of the cooking cycle;

- simultaneous heating and cooking of several semi-finished products in one cycle (with a multi-section version of the device).

This technical result is achieved by the fact that the claimed device for heating and cooking semi-finished products with a food warmer function, containing a body with a heated water tank equipped with a water supply pipe and a drain pipe with a tap at the outlet, according to the invention, is additionally equipped with a stack in which a package with a semi-finished dish is fixed, the packing is installed on a heated water tank and pressed by a sealing cover hinged to the body, infrared emitters are installed on the inner surface of the sealing cover, and ultrasonic emitters are installed on the bottom of the heated water tank, from the outside, with At the same time, a heated water tank equipped with a water supply pipe and a drain pipe, together with a water circulation unit and a water heating unit, create a single circuit for its circulation, and the device for preparing semi-finished products with a food warmer function is controlled from the control panel, by transmitting a signal about the selected program for the preparation of a semi-finished product to the control unit, which controls the operation of the water circulation unit, the water heating unit, ultrasonic and infrared emitters.

The inventive device can be made in a multi-sectional version, characterized in that the above-described device for heating and preparing semi-finished products with a food warmer function is its sections combined in a common housing with thermally insulated compartments, water supply pipes and drain pipes of heated water tanks of each sections are equipped with controlled control valves and are interconnected by a water supply manifold and a drain manifold, respectively, while using a water circulation unit, a water heating unit, a control unit, a control panel common to the multi-section version of the device, and each heated water tank is additionally equipped with a level sensor water and water temperature sensor.

Such a scheme allows, on the one hand, to heat up and cook several dishes at the same time, and on the other hand, to maintain the set temperature of the dishes after the end of the heating and cooking cycle. Moreover, it can be both the same dishes and different ones. An individual heating and cooking program for each dish is set by supplying and shutting off heated water to the heated water tank of the corresponding section of the device, as well as turning infrared and ultrasonic emitters on and off.

The presence of a sealing gasket 4 on the sealing cover 3 ensures the tightness of the device for heating and cooking semi-finished dishes with a food warmer function. Next, the user turns on the device and on the control panel 19 starts the program selected for this dish-semi-finished product for its heating or cooking. The signal from the control panel 19 goes to the control unit 13, which first turns on the water circulation unit 14, and then the water heating unit 15, ultrasonic emitters 10 and infrared emitters 6.

Heated by the water heating unit 15 to 95°±1°C, water 18 through the water supply pipe 8 enters the heated water tank 7, gives off its heat to the package with the semi-finished product 11 and through the drain pipe 9, the water circulation unit 14, the unit heating water 15, already heated to a predetermined temperature (95 ° ± 1 ° С) through the water supply pipe 8, is again fed into the heated water tank 7. This cycle is repeated several times until the end of the heating or cooking cycle.

To eliminate stagnant zones of water 18 in the heated water tank 7 and for more uniform heat transfer to the package with the semi-finished product 11, ultrasonic emitters 10 are turned on during the cooking process, which, through vibration, create water 18 in the heated water tank 7, thereby excluding the above indicated shortcomings.

To speed up the heating or cooking process, infrared emitters 6 are turned on, heating the package with the semi-finished product 11 from above, while the temperature created by them should not exceed the allowable temperature for the packaging material.

At the end of the heating or cooking mode, the device for heating and cooking semi-finished products with a food warmer function automatically switches to the mode of maintaining the set temperature of the semi-finished product until it is served to the consumer, in this mode, infrared emitters 6 and ultrasonic emitters 10 are turned off. At the end of the use of the device, water 18 is drained from the heated water tank 7 through the tap 17.

The multi-section device works similarly to the device described above for heating and cooking semi-finished products with a food warmer function. The difference lies in the individual adjustment of the water temperature in the heated water tanks 36 sections 26 due to its controlled circulation. Stopping the circulation of water at the end of the heating or cooking process or changing the volume of water circulation when section 26 switches to the bain-marie mode is carried out on command from the control unit 34 by controlled control valves 29 installed on the water supply pipes 27 and drain pipes 28 of the heated water tanks 36.

The water temperature sensors 38 installed in each heated water tank 36 transmit information to the control unit 34, which, if necessary, corrects the volume of water circulation in a particular heated water tank 36 to maintain the temperature of the semi-finished product preparation in it (95 ° ± 1 ° C) or another set temperature when section 26 switches to the food warmer function.

Water level sensors 37 installed in heated water tanks 36 transmit information about the water level in them to the control unit 34, which, if necessary, synchronizes the operation of controlled control valves 29 installed on the water supply pipes 27 and drain pipes 28, thereby thereby ensuring the maintenance of predetermined water levels in heated water tanks 36.

At the end of the use of the device, the water 18 is drained through the tap 39.

It should be noted that the device for heating and cooking semi-finished products with a food warmer function can be controlled not only from the control panel, but also from a connected computer or mobile device.

Although the specific results of the invention are disclosed, changes are possible in this embodiment without deviating from its principles and essence.
