The process of Sichuan pepper processing is both a destructive and preservation process. Customers often inquire about the issue of whether the peppers should be opened or closed, and the quality of the color. In fact, this is related to the adjustments of time, temperature, and humidity during the drying process. If the temperature is controlled lower, the proportion of opened peppers will decrease, and the time will correspondingly increase. If the temperature is higher, the moisture removal is faster, the opening will be larger, and the time will be shorter, but the color will worsen. If the temperature is low, the moisture removal is slow, and the drying time is longer, so a balanced choice of technology is required. Clean Energy Drying has developed drying equipment tailored to users' needs for drying Sichuan pepper, which mainly consists of: heat source, insulation system, air supply system, trolley, tray, and control system. It has the following main features:

1. Advanced temperature and humidity identification technology. It can identify the temperature and relative humidity of dry media in each section and accurately transmit the signal to the control system, implementing automatic control, adjusting the supply air temperature, humidity, airflow, and drying cycle. It automatically achieves moisture removal from the system, ensuring consistent and controllable moisture content in the finished product, and automatically implements the drying process. Time, temperature, and humidity processes can be set in segments according to the needs of drying Sichuan pepper. Complete the process curve to ensure quality while enabling unattended operation.

2. Advanced pulsating frequency modulation air supply system, utilizing small air supply and large circulation technology, overcomes the disadvantages of traditional air supply modes, such as high air supply resistance, poor hot air flow, wind counteraction, and low controllability of temperature and humidity, ensuring the entire temperature field is controllable for temperature and humidity. It also maintains a smooth and controllable dehumidification system, effectively guaranteeing the implementation of the drying process.
