[0040] In order to execute the control system described in Example 1, illustratively, Fig.14 As shown, the sampling unit includes: A second power unit 450; A container library 430, in which a plurality of sample containers 440 arranged in a preset direction are contained in a limited quantity, and the container library is driven to rotate along its own circumferential direction by a second power device; The sample inlet 432 is used to direct the sample into the sample container 440 which is rotated to the sampling point.

[0041] In this embodiment, the container library is driven to rotate by the second power device, thereby rotating the sample container to the position of the sample inlet, so that the feed inlet is connected with the sample container, so as to facilitate the sample to be sent into the sample container.

[0042] In this embodiment, the sampling unit may further include a support frame 420, on which the second power device and the container library are installed, and the support frame provides installation space and support for the container library and the second power device.

The injection port passes through the fixed disk. The injection port is arranged on the rotation path of the positioning cylinder. When one of the positioning cylinders rotates to a positioning point corresponding to the injection port, the injection port is connected to the positioning cylinder through a buffer sleeve.

[0045] The sample container is supported by rotating the lower plate, the height of the sample container is limited by rotating the upper plate, and the positioning cylinder positions the position of the sample container on the rotating lower plate, so that when the container library drives the sample container to rotate to the sampling point, the sample container is connected to the injection port.

[0051] This embodiment exchanges cold or heat with the fermentation liquid inside the tank through the constant temperature module and the heat conductive layer, thereby achieving constant temperature control of the fermentation liquid. At the same time, the insulation material filled in the insulation interlayer can effectively reduce the loss of cold or heat and improve the utilization rate of energy.

[0056] In addition, the fermentation control module can also obtain the progress calculation results. The fermentation control unit makes a fermentation completion judgment based on the progress calculation results. When the fermentation progress calculation results reach the preset fermentation progress, the fermentation control unit will control the discharge pipe valve at the bottom of the tank to open, so as to realize automatic discharge of the fermentation module.

[0057] In this embodiment, the sampling port of the sampling unit is arranged below the sampling valve tube, and the sampling valve tube is opened and closed at a fixed time to enable the fermentation liquid in the tank to discharge a preset amount of fermentation liquid to the outside at a preset time interval, and the discharged fermentation liquid flows into the sample container through the sampling port.

[0059] The Gastrodia elata raw material is put into the feed hopper and the Gastrodia elata powder can be temporarily stored in the temporary storage box. After the fermentation is completed and the fermentation liquid is discharged, the fourth power device drives the discharge control plate to move linearly to open the second discharge port. At the same time, the third power device drives the push plate to move linearly to completely push out the Gastrodia elata powder in the temporary storage box, thereby realizing automatic addition of Gastrodia elata powder.

The powder scraper is driven to rotate along the inner wall of the storage hopper by the sixth power device 521 installed on the top of the storage hopper.

[0062] The bacterial powder for fermentation is stored in a limited amount through the storage hopper, and the powder discharging screw is driven to rotate by the seventh power device to drive the bacterial powder to be input into the tank body, thereby realizing automatic addition of the bacterial powder, and the powder scraper is driven to rotate by the sixth power device to scrape off the bacterial powder attached to the inner wall of the storage hopper.

[0063] In this embodiment, a powder adding port 523 is provided on the top of the storage hopper for artificially adding bacterial powder. The powder discharging screw is connected to the seventh power device via a connecting shaft 527.

After reaching the preset capacity, the sampling valve tube is closed, and then the second power device continues to drive the sample container to rotate to the detection unit position, and the first power device drives the rotating upper plate to rise, so that the positioning cylinder is separated from the sample container, and then the sample container is pushed to the detection unit through the pushing module; S200: Acquire a first parameter and a second parameter collected in real time by a sensor unit, perform progress calculation according to the first parameter and the second parameter, and obtain a progress calculation result; S300: Generate a control signal to the fermentation unit, the sampling unit, and the detection unit according to the progress calculation result, so that the fermentation unit, the sampling unit, and the detection unit perform corresponding actions according to the control signal; Specifically, the fermentation control module can also obtain the progress calculation result, and the fermentation control unit makes a fermentation completion judgment based on the progress calculation result. When the fermentation progress calculation result reaches the preset fermentation progress, the fermentation control unit will send a discharge control limit number to the discharge pipe valve at the bottom of the tank body to open the discharge pipe valve and discharge the fermentation liquid. When the fermentation liquid is completely discharged (this state is achieved through liquid level sensor detection), a spray pipe connected to an external water source is set in the tank body to spray cleaning liquid into the tank body, and the eighth power device drives the agitator to rotate, thereby realizing cleaning of the inside of the tank body. After cleaning for a preset number of times, the fermentation control module will send a feed empty signal to the feed module and the bacterial powder adding module to add Gastrodia elata powder and fermentation bacterial powder into the tank body, and then start the fermentation work again.
