Processed food materials are placed in the steam cabinets, and the steam cabinets can prepare breakfast, lunch and dinner. Office workers can not only conveniently solve the problem of dining, but also save more time in dining. However, a large amount of steam will come out of the steam cabinet when taking food.

The compressor 5 and the second compressor 6 are connected to the cooling and dehumidifying device 2 and the condensing device 4. The condensing device 4 can slowly release the heat generated by the cooling and dehumidifying device 2, the first compressor 5 and the second compressor 6 when they are working into the room, which can well protect the stability of the temperature of the indoor environment, and has little effect on the ambient temperature around the steam cabinet 9, making people feel comfortable. A pressure relay 8 is provided in front of the cooling and dehumidifying device 2. The pressure relay 8 is used to adjust the defrosting time and the preservation time of the steam processing equipment during refrigeration and preservation, and increase the working stability of the steam processing equipment during refrigeration and preservation. The condensing device 4 is connected through the output pipeline 3. The condensing device 4 is arranged on one side of the circulating fan 1. The condensing device 4 includes a cooling fan 41, a condenser 42 and a cold storage tank 43.The cooling fan 41 is arranged on the condenser 42, and the condenser 42 is arranged on the cold storage tank 43.

The setting of the cold storage tank 43 can effectively The low heat retained when the food is kept fresh can be used to cool the hot steam, so that the energy can be effectively recycled and the energy loss of the device can be reduced. When the steam cabinet 9 is heated, the condensing device 4 does not work. When the steam cabinet 9 stops heating, the condensing device works. When the liquid temperature in the cold storage tank 43 is higher than the set 3°C, the second compressor 6, the condenser 42 and the cooling fan 41 cool down the liquid until the liquid temperature in the cold storage tank 43 is lower than 0°C.

[0021] Workflow Description:

[0022] 1. Steam processing: When all the food in the steam cabinet 9 is steamed and heated and needs to be taken out, the steam cabinet 9 enters the steam processing mode, and the steam enters from the steam cabinet 9 through the control of the circulating air valve 11 and the circulating fan 1, and first enters the steam input channel 21 to enter the first cavity 211 and the second cavity 212 in the first cooling dehumidifier 22, and the steam is cooled and dehumidified for the first time. The steam that has been cooled and dehumidified for the first time enters the third cavity 241 and the fourth cavity 242 in the second cooling dehumidifier 24 through the U-shaped channel 23, and the steam is cooled and dehumidified for the second time. If the steam is cooled and dehumidified only once, the compressor needs to run at high power, which is not conducive to the stability of the circuit. The secondary cooling and dehumidification of the steam can reduce the impact of the steam processing equipment on the indoor power grid, and does not need to output high power at one time, which is stable. A fixed circuit is formed, and the effect of secondary cooling and dehumidification can save time for steam processing and improve work efficiency. The steam after secondary processing enters the steam output channel 25, and then flows back to the steam cabinet 9 through the output pipe 3, completing a cycle of cooling and dehumidifying the steam. Then the steam treatment equipment continues to circulate and treat the steam. The treated steam is compatible with the steam in the steam cabinet 9 for cooling and dehumidification. The steam treatment equipment then extracts steam from the steam cabinet 9 for circulation treatment. When the temperature in the steam cabinet is greater than 75°C, the steam treatment equipment continues to cool and dehumidify. After the steam equipment has cooled and dehumidified the steam for multiple cycles, the internal temperature of the steam cabinet 9 is lower than 70°C, and the internal moisture content reaches the emission standard, the steam equipment stops working, the circulating air valve 11 and the circulating fan 1 are closed, and the steam treatment mode is closed.

[0023] 2. Refrigeration and preservation: before the steam cabinet 9 needs to be replenished with food, the steam cabinet 9 enters the refrigeration and preservation mode. The internal temperature of the steam cabinet 9 is high, and the steam processing equipment needs to reduce the temperature of the steam cabinet 9 to between 5°C and 8°C. The liquid in the storage cold tank 43 enters the second compressor 6 through the first compressor 5 and then enters the cooling and dehumidification device to cool and dehumidify the steam extracted from the steam cabinet 9. The steam enters the steam cabinet 9 through the control of the circulating air valve 11 and the circulating fan 1, and first enters the steam input channel 21 to enter the first cavity 211 and the second cavity 212 in the first cooling and dehumidifier 22, and the steam is cooled and dehumidified for the first time. The steam that has been cooled and dehumidified for the first time enters the third cavity 241 and the fourth cavity 242 in the second cooling and dehumidifier 24 through the U-shaped channel 23, and the steam is cooled and dehumidified for the second time. The steam is compatible with the steam in the steam cabinet 9 for cooling and dehumidification. The steam processing equipment then extracts steam from the steam cabinet 9 for circulation processing. After multiple cycles of cooling and dehumidifying the steam, the temperature in the steam cabinet reaches a preset 5°C-8°C. The staff opens the steam cabinet 9 and puts the food into the steam cabinet 9 for refrigeration and preservation. When the temperature in the steam cabinet 9 exceeds 8°C, the steam processing equipment starts the refrigeration and preservation work. When the temperature of the steam cabinet 9 is lower than 5°C, the steam processing equipment stops the refrigeration and preservation work. When the refrigeration and preservation function of the steam cabinet 9 exceeds 90 minutes, the steam cabinet 9 stops working and enters the defrosting state. The pressure relay 8 performs a 15-minute defrosting process. After the defrosting is completed, it takes another 5 minutes to discharge the residual defrosting water. After 20 minutes of defrosting, the steam processing equipment continues to work in the refrigeration and preservation state.

[0024] The steam processing equipment can not only heat food with steam, but also keep food fresh in the refrigerator, thereby improving the utilization rate of the equipment and reducing the reinvestment of other equipment. The equipment is compact in design, which solves the contradiction of insufficient space and makes the equipment more environmentally friendly.
