[0054] Working principle of the present invention:

[0055] First, the Chinese herbal medicine to be fermented is placed in the placement groove on the top of the placement plate 13, and then the bacteria required for fermentation are sprinkled on the Chinese herbal medicine, and then the door panel 7 is opened, and the placement plate 13 is pushed onto the placement rack 12. In the process of pushing the placement plate 13, the bottom wall panel of the placement plate 13 will move on the roller 27, and the roller 27 will rotate during this process. At the same time, the roller 27 will also effectively abut against the protrusion 26. When the protrusion 26 contacts the roller 27, the placement plate 13 will move upward. When the contact between the protrusion 26 and the roller 27 exceeds the lowest point of the protrusion 26, the placement plate 13 will move downward. Through the setting of the protrusion 26 and the roller 27, the placement plate 13 can vibrate to a certain extent during the process of being pushed onto the placement rack 12, which is beneficial to vibrate the bacteria sprinkled on the Chinese herbal medicine, so that the bacteria can be distributed deep in the Chinese herbal medicine, thereby making the distribution of the bacteria on the Chinese herbal medicine more uniform, which is beneficial to the subsequent fermentation.

[0056] After the multiple placement plates 13 are pushed onto the placement rack 12, the door panel 7 is closed so that the door panel 7 abuts against the sealing airbag 29, thereby achieving effective sealing of the fermentation box 2, which is beneficial to prevent external bacteria from entering the fermentation box 2. After the sealing is completed, the sterile cloth 4 is blocked on the outside of the fermentation box 2 through the electric slider opened on the column 3.

[0057] After the sterile cloth 4 is supported on the outside of the fermentation box 2, the air heater 9 is used to effectively heat the gas entering the fermentation box 2 by turning on the fan 11 and the air heater 9. After the fan 11 is turned on, the fan 11 will extract a certain amount of gas from the fermentation box 2, and then the fermentation box 2 is in a negative pressure state. When the air pressure in the fermentation box 2 is lower than the preset pressure value of the pressure valve 19, the pressure valve 19 is opened, so that the air heated by the air heater 9 can enter the fermentation box 2. Before the gas enters the fermentation box 2, it will be filtered by the sterile cloth 4, which can effectively prevent bacteria or dust in the outside air from entering the fermentation box 2, thereby affecting the fermentation of the Chinese herbal medicine in the fermentation box 2. After being filtered by the sterile cloth 4, the gas will also be purified by the plasma purifier 10, which can make the air entering the fermentation box 2 close to the sterile state, thereby effectively reducing the adverse effects of external bacteria on the fermentation of the Chinese herbal medicine in the fermentation box 2.

[0058] After entering the fermentation box 2, the heated air will pass over the top of the placement plate 13, and then flow from top to bottom between two adjacent placement plates 13 in the fermentation box 2. During the flow, the temperature in the fermentation box 2 can be effectively increased. After the airflow flows into the gap at the end of the placement rack 12, the airflow will be divided into two streams, flowing through the two sides of the electric heater 17 respectively, one of which blows on the top of the placement plate 13 located below, and the other will enter the rectangular hole 18 under the guidance of the arc plate 16, and then blow into the hollow layer inside the protrusion 26 through the rectangular hole 18. The hot air flow passes through the hollow layer of the protrusion 26, so that the temperature of the bottom wall plate of the placement plate 13 will also increase, and then after the temperature of the bottom wall plate of the placement plate 13 is increased, the Chinese herbal medicines on the placement plate 13 can be fermented in an environment with suitable temperature, which is conducive to the growth of the flora.

[0059] When the airflow passes through the electric heater 17, the airflow will contact the thermistor 31. The resistance of the thermistor 31 will increase as the temperature of the airflow increases. When the resistance of the thermistor 31 increases, the current in the circuit composed of the thermistor 31, the electric heater 17 and the light bulb 32 will decrease. After the current decreases, the power of the electric heater 17 and the light bulb 32 will decrease, thereby reducing the amount of heat used by the electric heater 17 to perform secondary heating on the airflow. This is beneficial to avoiding the situation where the bacterial flora becomes inactive due to excessively high airflow temperature. When the resistance of the thermistor 31 decreases, the power of the electric heater 17 will increase, thereby heating the air more strongly, allowing the electric heater 17 to effectively perform secondary heating on the airflow, thereby avoiding the situation where the Chinese herbal medicine is insufficiently heated due to excessively low airflow temperature.

[0060] As the resistance of the thermistor 31 decreases, the brightness of the light emitted by the bulb 32 will also decrease. As the resistance of the thermistor 31 increases, the brightness of the light emitted by the bulb 32 will also increase. Therefore, the technician can judge the temperature of the airflow in the fermentation box 2 by observing the brightness of the light emitted by the bulb 32 on the light board 30.

[0061] As the airflow flows, after the airflow flows to the air outlet pipe 23, the temperature sensor 24 inside the air outlet pipe 23 will effectively monitor the temperature of the airflow. When the temperature sensor 24 detects that the temperature of the airflow is reduced, it will send a first request message to its built-in controller. After receiving the first request message, the controller will generate a first control message. The controller then sends the first control message to the air heater 9, so that the air heater 9 emits a higher power, so that the temperature entering the fermentation box 2 is increased, and then the temperature in the fermentation box 2 is controlled to increase. When the temperature sensor 24 detects that the temperature of the airflow is increased, it will send a second request message to its built-in controller. After receiving the second request message, the controller will generate a second control message. The controller then sends the second control message to the air heater 9, so that the power emitted by the air heater 9 is reduced, so that the temperature entering the fermentation box 2 is reduced, and then the temperature in the fermentation box 2 is controlled to decrease. The temperature in the fermentation box 2 is effectively raised and lowered by the temperature sensor 24 and the air heater 9, so that the temperature in the fermentation box 2 approaches a balanced state.

[0062] After leaving the fermentation box 2, the air flow will enter the air duct 22 through the fan 11, and then enter the dispersion pores 21 through the rectangular grooves 20. After the dispersion work of the dispersion pores 21, the gas can be effectively contacted with the bactericide pre-added in the water tank 14, thereby reducing the bacterial content in the gas, which is beneficial to avoid the harmful bacteria produced during the fermentation of Chinese herbal medicine being discharged into the outside atmosphere with the air flow. The harmful bacteria can be killed by the water tank 14, which can effectively maintain the stability of the external environment.

[0063] After being purified by the bactericide, the gas will enter the annular groove opened inside the rectangular ring 5 through the exhaust pipe 28, and then spray upward through the nozzle 6. After the spraying is completed, the bacteria filtered by the sterile cloth 4 can be effectively disinfected, which is conducive to maintaining the surrounding environment of the device in a relatively sterile state, and further reducing the bacteria in the surrounding environment from entering the fermentation box 2. The molecules of the bactericide contained in the surrounding air can be effectively adsorbed on the sterile cloth 4. After the sterile cloth 4 adsorbs the bactericide, it is helpful to avoid the bactericide from entering the fermentation box 2 to kill the bacteria required for fermentation. At the same time, the plasma purifier 10 can also further eliminate and filter the molecules of the bactericide contained in the air, further avoiding the bactericide from entering the fermentation box 2 to kill the bacteria required for fermentation.

[0064] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention.
