The jujube multi-layer drying line usually consists of the following main equipment:

 1. Drying room: The drying room is the core equipment of the red date drying line and is used to dry red dates with hot air. The drying room usually adopts a multi-layer structure, and each layer has a drying rack or drying tray for placing red dates.

 2. Hot air generator: The hot air generator is a device that provides the hot air required for the drying room. It usually consists of a burner, a heat exchanger and a fan, which can generate high-temperature hot air and send it into the drying chamber.

 3. Fan: The fan is used to transport hot air from the hot air generator to the drying room and maintain air circulation in the drying room. The power and air volume of the fan need to be selected according to the size of the drying room and drying needs.

 4. Temperature control system: The temperature control system is used to monitor and control the temperature in the drying room. It usually includes a temperature sensor, temperature controller and actuator, which can adjust the working status of the hot air generator according to the set temperature parameters to achieve stable control of the temperature in the drying room.

 5. Conveying system: The conveying system is used to transport the red dates into the drying chamber from the feed end, and take out the dried red dates from the discharge end after drying is completed. The conveying system may use conveyor belts, screw conveyors or other suitable devices.

 6. Filtration equipment: The filtration equipment is used to purify dust and impurities in the hot air and maintain the cleanliness of the hot air to prevent contamination of the red dates.

 7. Control system: The control system is used to monitor and control the operation of the entire drying line. It can integrate temperature control, conveyor system control, fan control and other functions, and provide a human-machine interface for operators to set and monitor.
