[0030] This example is a single device used for fermentation alone, which is suitable for fermentation of a small amount of material in the laboratory and small-batch trial production in the process verification stage of the factory. The use steps are as follows:

[0031] 1. Open the waste valve, connect the power supply of the device, and turn on the PLC switch. At this time, the fan rotates at low speed to maintain positive pressure in the cavity on the inner wall of the support.

[0032] 2. Start the feeding program on the computer, and the drum starts to rotate. Open the feeding port shutter, and add the inoculated material into the drum according to the specified amount.

[0033] 3. After the feeding is completed, close the feeding port shutter, end the feeding program, and the drum stops rotating.

[0034] 4. Start the fermentation program, and the system automatically adjusts the working state of each module according to the temperature and humidity monitoring data, and the material starts to ferment. The suitable temperature for material fermentation is 20-42°C, and the suitable relative humidity is 50-80%.

For example, if the material temperature is higher than the set value, the drum starts to rotate, and the fan speed is increased to blow a large amount of cold air to cool the material. When the material temperature drops to the set range, the drum stops rotating, and the fan speed is reduced to a low speed state.

[0036] 6. After the fermentation is completed, the drying program is automatically started, at this time the drum starts to rotate, the electric heating wire is powered on to heat, and the fan speed is increased to make the moisture in the material gradually lost. The drying temperature is generally between 40-105°C, and the drying time is 1-4 hours. After the drying program is completed, the electric heating wire is powered off to stop heating, and when the material temperature drops to below 30°C, the drum stops rotating, and the fan speed is reduced to a low speed state.

[0037] 7. After the material is dried, the discharge port is opened, the discharge program is started, and the drum rotates clockwise to discharge the fermented and dried material from the discharge port.

[0038] 8. After the discharge is completed, the discharge program is exited, the discharge port is closed, and the cleaning program is started. The drum rotates, and the high-pressure spray head sprays water to clean the drum. The cleaning time is generally 10-15 minutes. After cleaning is completed, the high-pressure spray head stops spraying water, the fan is started, and the electric heating wire is powered on to heat, so as to dry and disinfect the cavity and the drum at a high temperature. The drying temperature is 105-120°C, and the drying time is generally 30 minutes.

[0039] 9. After drying is completed, the equipment is powered off, and the waste valve is closed. Example 2

[0040] This example is a series connection of multiple devices and a double-layer parallel use mode, which is suitable for large-scale material fermentation in a factory. The basic use principle is the same as that described in Example 1.

[0041] By connecting the discharge port and the feeding port of adjacent devices, the devices can be used in series, and unified feeding, fermentation, drying, and discharging can be achieved. In addition, the device can be further upgraded in a double-layer parallel manner to maximize the use of space resources. The temperature, humidity, and rotation speed of each device can be independently controlled and managed simultaneously through the PLC control system, greatly improving the fermentation capacity of the material and reducing the labor intensity of the operator.
