Description

Automatic energy-saving safe steaming cabinet device that packs into and take out

Technical Field

The invention relates to a food steaming cabinet, in particular to an energy-saving safe steaming cabinet device capable of being automatically loaded and unloaded.

Background

In the catering industry, the steaming cabinet is widely applied to canteens such as hotels, schools, factories and the like, can be used for steaming meat foods such as meat, seafood, chicken, duck, fish and the like, even can be used for stewing soup and can be used for sanitary disinfection of articles such as tableware and the like besides rice, steamed bread and steamed stuffed buns. The steam cabinet heats water to boil by using electricity or gas, and the generated steam is used for cooking food or sterilizing articles at high temperature; when steaming food in a closed mode, the steaming cabinet is internally pressurized properly, and the proper heating temperature is set, so that the food can be steamed more quickly, and the food is more delicious and tasty while the time and the energy are saved.

At present, the types of steam boxes on the domestic market are many, for example, "a high-performance energy-saving commercial steam box and a control method thereof" disclosed in the Chinese patent application No. 201810559330.2, "an electric dual-purpose intelligent rice steaming cabinet" disclosed in the Chinese patent application No. 201811157693.X and "an energy-saving steam cabinet with a steam generator" disclosed in the Chinese patent No. ZL201820579499.X, and the like, the steam cabinets have the characteristics that the general energy efficiency utilization rate is low, the energy efficiency reaches 70% according to the relevant standard specification, most of the existing steam boxes can not achieve real effective energy saving, and the main reason is that most of energy consumption of the existing steam boxes is wasted, the existing steam boxes are used for loading or taking out food through manual door opening, frequent cabinet opening is needed in the process of continuously steaming food, a large amount of steam is leaked out each time of cabinet opening, steam is needed to be pressurized and heated after the door closing, and a large amount of heat energy is wasted, meanwhile, the steam is discharged, so that potential safety hazards of scalding are easily caused.

Aiming at the technical problems of the steam cabinet, Chinese patent No. ZL201820597468.7 discloses a high-efficiency energy-saving steam recovery steam cabinet, which comprises a cabinet body, wherein a cabinet door is arranged on the cabinet body, a steam generator is arranged at the bottom in the cabinet body, a water inlet is arranged at the bottom of the steam generator, the water inlet penetrates through the bottom of the cabinet body and is connected with a water inlet valve, an electric heating module is arranged in the steam generator, a steam rack is arranged above the steam generator, a steam recovery port is arranged at the rear side of the upper part in the cabinet body, an automatic control system is arranged at one side of the top in the cabinet body and comprises a temperature detection module, a humidity detection module, a pressure detection module and a wireless module, the steam recovery port is connected with a steam recoverer through a first pipeline, and steam is connected with the position between the upper steam generator and the steam rack of the, the steam recoverer comprises a honeycomb heating device and a steam recovery pump, and the automatic control system is electrically connected with the electric heating module and the steam recoverer. This patent application utilizes steam recoverer to carry out cyclic utilization with the steam that produces, fully utilizes the heat of steam, has reached certain energy-conserving effect, but it needs external steam recoverer, needs to cooperate more power consumption modules, and not only product structural design is more complicated, and the increase of consumer has also increased the power consumption energy consumption moreover, and has increased the equipment spoilage, and energy-conserving effect is not good. Chinese patent No. ZL201921830700.8 discloses "stainless steel steamed rice cabinet for dining room", the steamed rice cabinet of this application, including the cabinet body and articulate the cabinet door in cabinet body one side, the internal steam tray frame that is provided with of cabinet, steam tray frame is last to have set gradually a plurality of layers of steam tray along vertical direction, steam tray is provided with the handle towards the side of cabinet door, one side that the cabinet is internal to be located the cabinet door hinged end articulates there is a steam seal door, steam seal door is last to set up a plurality of dishes groove of getting that supply steam tray card to go into along vertical direction, the interior bottom of the cabinet body is provided with the basin, the basin bottom is provided with the steam heating wire. According to the application, the situation that when the steaming trays are taken, the cabinet body is directly and comprehensively opened to release steam can be avoided, the possibility that an operator is scalded by the steam is reduced, but because the steaming trays in the cabinet body are communicated, when one steaming tray is taken out independently, steam pressure release and discharge can be carried out again, steam heat energy is still partially released, and the overall energy-saving effect of the steaming cabinet is influenced; in addition, even when one steaming tray is taken out independently, the risk of scalding the operators still exists due to the leakage of the steam.
