[0059] When the drying function is started, an appropriate amount of water is injected into the first tank body 2. Preferably, the water is deionized water with a TDS of less than 20ppm.

In the preservation function, the ultraviolet generator 13 and the microwave generator 15 are started according to actual needs to perform auxiliary enzyme stewing treatment on the medicinal materials on the tray 11. For example, the microwave enzyme stewing preservation function of Cistanche deserticola can be used in combination with the soaking and cleaning process, the steaming and stewing process, and the drying and preservation process.

[0061] In the above-mentioned drying function and preservation function, there are three control operation modes as follows:

[0062] Strategy 1: Maintain the hot water flow rate unchanged and adjust the vacuum drying pressure by adjusting the frequency of compressor 5; or maintain the compressor 5 frequency unchanged and adjust the vacuum drying pressure by adjusting the hot water flow rate to achieve precise control; the above two methods can achieve constant pressure vacuum drying or preservation operations.

[0063] Strategy 2: When the vacuum pressure in the integrated machine 1 is stable for a period of time, the compressor 5 is turned off, the third valve 403 is opened, air is filled into the integrated machine 1 and maintained at normal pressure, the third valve 403 is closed after a period of time, and the compressor 5 is turned on again to evacuate the air, and the above operation methods are repeated alternately to achieve floating pressure vacuum drying or preservation operations.

[0064] Strategy 3: On the basis of the control of the vacuum drying function, after the vacuum pressure is stable for a period of time (low-pressure working point), change the operating frequency of compressor 5 to increase the vacuum pressure (high-pressure working point) and maintain the operation for a period of time, then change the operating frequency of compressor 5 to reduce the vacuum pressure (low-pressure working point), and repeat the above high- and low-pressure working operation methods alternately to achieve floating pressure vacuum drying or preservation operations.

[0065] Among the above three control strategies, when the vacuum pressure in the integrated machine 1 is controlled between 10-25 kPA and the hot water temperature is controlled between 60-100°C, it is used for the vacuum drying process. When the vacuum pressure in the integrated machine 1 is controlled between 1-5 kPA and the hot water temperature is controlled between 20-60°C, it is used for the vacuum preservation process.

The control device performs real-time detection and control of key process parameters, provides automation and accurate control of processing equipment, and can improve the processing performance of medicinal materials and reduce labor intensity.

The temperature of the cleaning liquid is controlled by the second temperature sensor 32 and the second electric heating tube 31. The cleaning temperature range is selected to be 20-30°C to achieve the best cleaning effect. The magnetic field generator 9 on the cleaning pipeline is turned on to magnetize the cleaning liquid to enhance the cleaning effect of removing pesticide residues. The magnetic field strength is preferably 5000-20000Gs. After cleaning is completed, the cleaning function is turned off.

[0083] (2) The second step is to start the preservation function, and perform the vacuum preservation and cleaning functions simultaneously. The compressor 5 is started to vacuum the integrated machine 1, and the vacuum unit 33 is turned on to vacuum the second tank body 3. When the pressure of the second tank body 3 is below 20 kPA, the vacuum unit 33 and the ninth valve 409 are closed, and the washed shiitake mushrooms on the tray 11 are continuously heated by hot water circulation. During the vacuum preservation process, the water in the shiitake mushrooms is continuously evaporated, and after being compressed by the compressor 5, it is heat-exchanged with the circulating hot water in the heat exchanger 6 to recover the residual heat of the steam. The vacuum dry preservation process preferably uses the dry preservation control strategy 3 to perform the dry preservation operation. During the dry preservation process, the humidifier 16 is appropriately turned on to humidify the shiitake mushrooms to prevent excessive water loss from causing damage to the internal tissue of the shiitake mushrooms. When the dry preservation is completed, the dry preservation function is turned off.

[0084] (3) In the third step, based on the second step, the ultraviolet generator 13 and the microwave generator 15 on the integrated machine 1 are turned on to perform enzyme inactivation preservation treatment, wherein the power of the ultraviolet generator 13 is preferably 300-500W, and the ultraviolet irradiation time is 5-15min. The power of the microwave generator 15 is preferably 300-500W, and the microwave irradiation time is 5-15min. After the enzyme inactivation preservation is completed, the enzyme inactivation preservation function is turned off.
