Abstract

FIELD: food industry; storage.

SUBSTANCE: invention relates to a public catering thermal equipment for storing food in a heated state, and more specifically for short-term storage of ready-made snacks for beer, their demonstration and sale to the consumer at fast food enterprises, which includes heating and maintaining the temperature. Steam table for the beer factory with a tasting room contains: rack with shelfs, flooding tank, heating elements for water heating, relay for adjusting temperature and liquid level, drain valve for draining water. At the same time, the water tank is a closed vessel equipped with an inlet and an outlet that are connected to a heat exchanger circuit with two pumps connected to a relay for adjusting the temperature and the liquid level in the mantle along which fluid circulating the heat from the wort copper is circulated.

EFFECT: invention allows to keep food warm.

Description

The technical field to which the invention relates:

The invention relates to heating equipment for public catering, intended for preserving food in a heated state, and more specifically for short-term storage of ready-made snacks for beer, their demonstration and sale to the consumer at fast food enterprises, which includes heating and maintaining the temperature.

The prior art:

Consider one of the Bertos food warmers. G7BM4M - food warmer with gas energy source. This model may well serve as a model of food warmer with heating dishes according to the principle of a water bath.

The Bertos G7BM4M has a fuse against unauthorized draining of water.

Food Capacity - GN: 1x GN1 / 1. The height of the model is 90 cm, length - 70, width - 40 cm. Power - 3.6 kW. Weight - G7BM4M - 65 kg.

The tecnoinox food warmer BM70E / 0 160095 is also known. The bathtub with rounded corners (providing a more thorough cleaning) has dimensions suitable for accommodating containers of the Gastro Norm type, therefore it is fully compatible with other kitchen equipment. Water is drained through a retractable extension on the front of the appliance, equipped with a safety device against accidental opening.

In electrical models, the temperature can be adjusted between 30-90 degrees. All models are equipped with an additional safety thermostat.

Famous Marmite universal water heating Airhot BM-11. The bottom of the gastronome containers is heated according to the principle of a "water bath", which allows you to maintain the taste and nutritional qualities of dishes without reheating and overdrying. Power 1.2 kW.

Disclosure of the invention:

The essence of this invention lies in the fact that the bulk of the thermal energy will come from a brewing boiler, in which the wort is heat treated at a temperature exceeding the temperature required for the operation of the food warmer. Heat directly to the food warmer will come through a heat exchanger connecting the boiler with the food warmer, through tubular connections that are connected to both the container at the bottom of the food warmer with hot water and the heat exchanger. Forced circulation of the fluid along the resulting circuit is carried out by pumps at the inlet and outlet. Pumps are turned on and off automatically during operation, depending on the performance of the thermal relay associated with the heating fluid inside the food warmer. The pumps are switched on when the temperature drops below a predetermined temperature range, and shutdown occurs when this range is exceeded.

For the case of preventive and repair work, the period of time the boiler enters the mode, and other cases of insufficient heat supply from the boiler, the food warmer is equipped with a small power heater that can maintain the temperature of the liquid in the food warmer at the required level. The heater comes into operation when the water temperature drops in the food warmer a few degrees below the lower limit of the range, when the thermal relay is fixed, the pumps are turned on, and it turns off at a temperature higher than the heater's temperature, but below the pump's activation border. The capacity of the food warmer is equipped with a drain valve.

A typical brewing boiler is a cylindrical vessel with a double spherical bottom, forming a steam jacket, designed to heat and boil the wort. Heating steam is held in a shirt in several places from the annular steam pipe; condensate is also removed from the jacket in several places to the condensate drain. Non-condensing gases from the shirt are periodically removed to the atmosphere through a tube.

Around the steam jacket is a heat exchanger with liquid. Heat from the steam jacket enters the heat exchanger through heat transfer. The container with liquid in the food warmer is equipped with a dry running protection device that prevents the inclusion of a heater in the absence of water in the container.

It is also possible to use secondary steam that escapes into the atmosphere by suctioning these vapors by a fan and forcing them into a surface condenser. The resulting warm water can be used to heat food warmers. In this case, the heat exchanger is connected to the condenser by tubular connections to drain hot condensate into the heat exchanger.

Claims (2)

1. A food warmer for a brewery with a tasting room, containing racks with tiled shelves, a tank for pouring water, heating elements for heating water, a relay for adjusting temperature and liquid level, a drain valve for draining the water, characterized in that the water tank is a closed container equipped with inlet and outlet openings that are connected to the heat exchanger circuit with two pumps connected to a relay to adjust the temperature and liquid level in the food warmer through which the liquid circulates heat from a brewing boiler. 2. Food warmer according to claim 1, characterized in that the contour of the heat exchanger includes an adjustable connection with a surface condenser that collects the liquid generated when using secondary steam removed into the atmosphere, by suction of this steam by the fan and forcing it into the surface condenser, the condensate that flows off through the connection to the heat exchanger, where it can be used together / instead of water circulating through the heat exchanger.
