Description

A steam recovery system for a commercial steam cabinet

technical field

The utility model patent relates to a steam recovery system, in particular to a heating and control system for recovering the steam required by commercial steam cabinets that can achieve substantial energy saving and consumption reduction. the

Background technique

At present, most of the existing commercial steaming cabinets use electricity or gas to heat the water in the water tank, so that the water is converted into saturated water vapor, and the heat is carried by convective heat exchange with the food in the steaming cabinet to achieve the effect of heating and steaming the food. . Another kind of steam cabinet directly uses the steam generated by the central boiler to introduce into the steam cabinet, and the principle of other aspects is still the same. However, using steam as a heat medium actually consumes a lot of heat:

Taking a conventional gas steamer as an example, the water stored in the water tank of the steamer is converted into water vapor by the flame generated by the combustion of gas. Under normal pressure, boiling water at 100 degrees Celsius per kilogram needs to absorb 2257.2 kilojoules of heat before it can be converted into water. For steam, this energy is called the "latent heat of vaporization" of water, and the specific heat capacity of water vapor at constant pressure is 1.842 kilojoules per kilogram per degree Celsius. That is to say, the heat consumed by converting every kilogram of boiling water at 100 degrees Celsius into water vapor under normal pressure can increase the temperature of 1 kilogram of 100 degrees Celsius water vapor at constant pressure to 1225 degrees.

The food in the steamer can only contact with a small amount of steam in the steamer for heat exchange due to the volume and shape of the container, and most of the steam is directly discharged out of the steamer without heat exchange with the food. Therefore, the main power consumption of the commercial steamer is consumed on the unheated steam that is directly discharged outside the steamer, resulting in a great waste of energy. the

Chinese patent CN201120128598.4 discloses a numerical control fast electric steaming cabinet, including a steaming box, a device box is arranged at the bottom of the steaming box, an electric steam engine is arranged in the device box, and a water inlet pipe with a solenoid valve is connected to the electric steam engine and an air supply pipe with an air intake valve, the air supply pipe communicates with the steam box, a drain pipe with a drain valve is connected at the bottom of the electric steam engine, a control panel is fixed on the device box, and the control panel is connected with the electric steam engine. This structure is complex, and the waste of electric energy is serious, and the use efficiency is relatively low. the

Invention content

The utility model mainly solves the deficiencies in the prior art, and provides a steam recovery system for commercial steam cabinets with simple structure and capable of recycling steam.

The above-mentioned technical problems of the utility model are mainly solved by the following technical solutions:

A steam recovery system for a commercial steam cabinet, comprising a steam chamber, the lower end of the steam chamber is provided with a steam distributor, the bottom of the steam chamber is provided with a steam generator, and the steam distributor is The pipeline communicates with the steam chamber, the steam generator communicates with the steam distributor through a blower, and the steam generator communicates with the steam chamber through an air return pipeline.

The steam recovery system drives the steam in the steam generator into the steam distributor by increasing the blower, and after the steam distributor equalizes the flow and pressure, it enters the intake pipe, and then discharges into the steaming chamber to steam the food. After that, the uncondensed steam in the steamer returns to the steam generator through the negative pressure generated by the blower in the return air pipeline for reheating. Thereby the recycling of steam is completed. the

The beneficial effect of the utility model is that: the steam recovery system of the commercial steamer can eliminate most of the steam escape loss in the steamer. The steam airflow is pressurized by the blower, and after the steam distributor equalizes the pressure and flow, the high-speed steam can fully contact the food by optimizing the structure and position distribution of the intake pipe. In addition, the blower can also generate negative pressure in the steam return pipe, which is convenient for recovering the steam that can only escape through the exhaust valve after heating the food. The large amount of latent heat of vaporization that is wasted as steam escapes is thus significantly reduced. the

As a preference, the air intake pipe is provided with spaced air intake pipes to communicate with the steam chamber, and the air return pipe is provided with spaced air return pipes to communicate with the steam chamber. Air pipes and return air pipes are symmetrically distributed on the side wall of the steaming chamber. the

The utility model provides a steam recovery system of a commercial steam cabinet, which has the advantages of simple structure, energy saving, consumption reduction and recycling. the
