[0011] The present invention also provides a desugaring method for generating vacuum negative pressure circulation cleaning, comprising a control system and the desugaring device for vacuum negative pressure circulation cleaning as described above, wherein the control system comprises a central processing unit, an operation panel, and a temperature sensor for detecting the temperature of steam produced by a steam box, wherein the steam box, an air pump, a cooling mechanism, an operation panel, and a temperature sensor are all electrically connected to the central processing unit, respectively, and a temperature critical value K is pre-stored in the central processing unit. The desugaring method for generating vacuum negative pressure circulation cleaning also comprises the following steps:

[0012] A. Before use, water is filled into the steam box and the soup box, and the food material to be desugared is placed in the steamer box. Then the user operates the operation panel to make the central processor generate a start signal, which controls the steam box to start and generate steam;

[0013] B. The steam generated by step A enters the air inlet interface of the three-way joint, and the steam in the three-way joint flows out from the second air outlet interface of the three-way joint and flows to the air inlet end of the pressure check valve. After the steam reaches the pressure, the pressure check valve is opened to make the steam flowing out of the air outlet end of the pressure check valve flow into the steamer box, so that the steamer box evaporates for M minutes and stops steaming for M minutes;

[0014] C. When the steam temperature detected by the temperature sensor is higher than the temperature critical value K, the signal of the temperature sensor is transmitted to the central processor, so that the central processor controls the steam box to stop generating steam. At this time, the push rod in the pressure check valve closes the air inlet of the pressure check valve under the action of the spring. After the air inlet is closed, the steamer box in a vacuum state will absorb the water in the soup box into the steamer box under the cooling action of the cooling mechanism, so that the food material to be desugared will be soaked for N minutes;

[0015] D. The central processor controls the steam box to generate steam again, and the steam causes the water in the steamer box to flow back into the soup liquid tank, and this cycle repeats S times;

[0016] E. After S cycles, the food to be desugared reaches the required concentration. The central processor starts the air pump to work, so that the gas generated by the air pump empties the water in the steamer box into the soup tank, and the work is completed.

[0017] As a preferred technical solution, the temperature sensor is fixed to the outer side wall of the three-way joint.

[0018] As a preferred technical solution, the temperature critical value K is an average value of several temperatures with better desugaring effects.

[0019] As described above, the present invention relates to a vacuum negative pressure circulation cleaning desugaring device and a desugaring method thereof, which have the following beneficial effects:

[0020] Compared with the prior art, the present invention adopts such a structure, in which the steam generated by the steam box passes through a three-way joint and a pressure one-way valve to process the rice grains placed in the steamer box, and the air along the way is discharged to the soup liquid tank, thus forming a vacuum negative pressure. At the same time, when the temperature sensor of the control system detects that the temperature of the steam is higher than the critical value K, the steam box stops working, the cooling mechanism is used to cool the reflux pipe, and combined with the air supply of the air booster pump, the water in the soup liquid tank is returned to the steamer box to circulate and clean and evaporate the rice grains, thereby ensuring that the food material to be desugared in the steamer box forms food with better desugaring effect, thereby greatly improving the quality of the food used by the user.

[0034] A. Before use, water is filled into the steam box 3 and the soup box 2, and the food material to be desugared is placed in the steamer box 1. Then, the user operates the operation panel 131 to make the central processor 130 generate a start signal, and the signal controls the steam box 3 to start and generate steam;

[0035] B. The steam generated by step A enters the air inlet interface 40 of the three-way joint 4, and the steam in the three-way joint 4 flows out from the second air outlet interface 42 of the three-way joint 4 and flows to the air inlet end of the pressure check valve 6. After the steam reaches the pressure, the pressure check valve 6 is opened to make the steam flowing out of the air outlet end of the pressure check valve 6 flow into the steamer box 1, so that the steamer box 1 evaporates for M minutes and stops steaming for M minutes;

[0036] C.

After the air inlet hole 6 is closed, the steamer box 1 in the vacuum state will absorb the water in the soup box 2 into the steamer box 1 under the cooling effect of the cooling mechanism 8, so that the food material to be desugared will be soaked for N minutes;

[0037] D. The CPU 130 controls the steam box 3 to generate steam again, and the steam causes the water in the steamer box 1 to flow back into the soup liquid box 2, and this cycle repeats S times;

[0038] E. After the food to be desugared reaches the desired concentration after S cycles, the central processor 130 turns on the air pump 5, so that the gas generated by the air pump 5 empties the water in the steamer box 1 into the soup tank 2, and the work is completed. It should be noted that the above S cycles can be repeated three to four times, but are not limited thereto, and can also be set to other appropriate times. The above-mentioned desugaring method for generating vacuum negative pressure circulation cleaning can be widely used in various rice steaming equipment.

The steam is sucked into the steamer box 1, so that the food material to be desugared in the steamer box 1 is soaked for N minutes, and the central processing unit 130 controls the steam box to generate steam again, and the steam causes the water in the steamer box 1 to flow back into the soup tank 2, and this cycle is repeated S times; after S cycles, the food to be desugared reaches the required concentration, and the central processing unit 130 turns on the air booster pump, so that the gas generated by the air booster pump empties the water in the steamer box 1 into the soup tank 2, and the work is completed; in this way, the water in the soup tank 2 flows back into the steamer box 1, and the rice grains are repeatedly circulated, cleaned, and evaporated.

[0040] Combination Figure 1 As shown, the temperature sensor 132 is fixed to the outer wall of the three-way joint 4.

[0041] As a preferred technical solution, the temperature critical value K is an average value of several temperatures with better desugaring effects.

[0042] As described above, the present invention relates to a vacuum negative pressure circulation cleaning desugaring device and a desugaring method thereof, which have the following beneficial effects:

[0043] Compared with the prior art, the present invention adopts such a structure, in which the steam generated by the steam box passes through a three-way joint and a pressure one-way valve to process the rice grains placed in the steamer box, and the air along the way is discharged to the soup liquid tank, thus forming a vacuum negative pressure. At the same time, when the temperature sensor of the control system detects that the temperature of the steam is higher than the critical value K, the steam box stops working, the cooling mechanism is used to cool the reflux pipe, and combined with the air supply of the air booster pump, the water in the soup liquid tank is returned to the steamer box to circulate and clean and evaporate the rice grains, thereby ensuring that the food material to be desugared in the steamer box forms food with better desugaring effect, thereby greatly improving the quality of the food used by the user.

[0044] In summary, the present invention effectively overcomes various shortcomings of the prior art and has high industrial utilization value.
