[0018] Example: A medicinal herb drying equipment includes a drying chamber, a hot air system, a tray rack 1, a drying tray 2, a temperature sensor, a pressure sensor, a humidity sensor, and a control system 3. The drying chamber includes a chamber body 4 and a door 5. The tray rack 1 inlet / outlet is formed on one side of the chamber body 4. A slide rail 6 is formed on the bottom surface of the lower end of the chamber body 4. The door 5 is hinged to one side wall of the chamber body 4, and the door 5 can seal the inlet / outlet of the tray rack 1. An air inlet system and an air outlet system are respectively formed on opposite side walls of the chamber body 4. The hot air system blows hot air evenly into the drying chamber through the air inlet system, and the air outlet system blows hot air into the chamber body 4. The exhaust airflow is controlled by temperature, humidity and pressure sensors, which can sense the temperature, humidity and air pressure inside the chamber 4. The temperature, humidity and pressure sensors are electrically connected to the control system 3 for communication. The control system 3 controls the operation of the hot air system. The tray frame 1 includes a multi-layer frame structure arranged at intervals from bottom to top and rollers 7 installed below the frame structure. The rollers 7 can slide into the chamber 4 along the slide rail 6 on the bottom surface of the chamber 4. Several drying trays 2 can be laid flat on each layer of the frame structure of the tray frame 1. Several ventilation holes are arranged at intervals on the bottom surface of the drying trays 2.

[0019] After cleaning, the medicinal materials are evenly spread in the drying trays 2, and then placed on the frame structure of the tray rack 1. After the drying trays 2 are full, the tray rack 1 is pushed so that its rollers 7 slide into the drying chamber through the slide rails 6 on the bottom surface of the drying chamber body 4. Then the door 5 of the drying chamber is closed, and the drying process is started. The hot air system starts to blow hot air onto the drying trays 2 in the drying chamber. The hot air first blows the moisture on the surface of the medicinal materials quickly, and then the low-temperature hot air continues to blow on the medicinal materials, so that the moisture inside the medicinal materials gradually evaporates and is removed, achieving full drying of the medicinal materials without damage during the drying process. The dried water vapor is promptly discharged to the outside of the drying chamber through the air outlet system, achieving efficient drying of the medicinal materials. During the drying process, the control system 3 can adjust the drying temperature, the air force of the fan 10, and the drying time according to the data transmitted by the temperature sensor, pressure sensor, and humidity sensor, realizing intelligent drying of medicinal materials.

[0020] The tray rack 1 has a 12-layer frame structure, with 3 drying trays 2 placed on each layer. Each drying tray 2 is relatively low, and the dense arrangement of the drying trays 2 inside the drying chamber increases the heat exchange efficiency of the hot air drying chamber, reduces drying time, and improves drying efficiency.

[0021] The air intake system is distributed on the left and right side walls of the chamber 4, and the air outlet system is located on the rear side of the chamber 4. This bidirectional air intake ensures that the drying speed is consistent on both sides of the chamber, preventing uneven drying.

[0022] The air intake system and air outlet system each include a mesh plate 8 and an air filter 9 installed on the side wall of the housing 4. Air from outside the housing 4 enters the housing 4 through the mesh plate 8 and the air filter 9, and air from inside the housing 4 is discharged to the outside of the housing 4 through the air filter 9 and the mesh plate 8. The air filter 9 filters the incoming air to prevent contamination of the medicinal materials.

[0023] The hot air system includes fans 10 and electric heating elements 11. Several fans 10 and electric heating elements 11 are evenly spaced in an array on both sides of the housing 4. The air blown out by the fans 10 is heated by the electric heating elements 11 before entering the housing 4. Several temperature sensors correspond to drying trays 2 on each layer of the tray frame 1. The control system 3 controls the operation of each fan 10 and each heating element. The air from the fans 10 is heated by the electric heating elements 11 to form hot air.

[0024] The box 4 is also provided with a left partition 12, a right partition 13 and a lower partition 14. The hot air system and the air inlet system are respectively housed in the space between the mesh plate 8 on the left side wall of the box 4 and the left partition 12, and between the mesh plate 8 on the right side wall of the box 4 and the right partition 13. The lower partition 14 is fixedly installed on the bottom surface of the box 4 at intervals. The slide 6 is located on the lower partition 14. The left partition 12, the right partition 13 and the lower partition 14 form a drying space to accommodate the tray rack 1. Ventilation holes are provided on the left partition 12, the right partition 13 and the lower partition 14.

[0025] Each layer of the tray frame 1 is also equipped with a turning slide 16, and a turning sliding rod is provided on the turning slide 16. Several soft turning blades 15 are spaced apart on the turning sliding rod. The turning sliding rod slides along the turning slide 16, causing the soft turning blades 15 to turn the medicinal materials in each drying tray 2. The tray frame 1 is also equipped with a turning drive device, which drives each turning sliding rod to slide back and forth along the turning slide 6. The tray frame 1 is also equipped with a power supply device to provide power to the turning drive device. During the drying process, the medicinal materials are also turned by the turning blades, which makes the drying efficiency higher and the drying more uniform.

[0026] The power supply device on the tray frame 1 is a plug electrically connected to the stirring drive device. A corresponding socket is provided on the side wall of the housing 4 opposite the inlet and outlet of the tray frame 1. After the tray frame 1 enters the housing 4, its plug can be inserted into the socket on the inner side wall of the housing 4 to supply power. The control system 3 controls the start and stop of the stirring drive device. When the tray frame 1 is pushed into the drying chamber, the plug and socket automatically connect, supplying power to the stirring drive device.

[0027] The turning and mixing drive device includes a motor, a synchronous transmission mechanism and lead screws. The motor is fixedly installed on the tray frame 1, and several lead screws are rotatably installed on each layer of the frame structure. The lead screws are movably screwed to the turning sliding rods, and the motor drives each lead screw to rotate synchronously through the synchronous transmission mechanism.
