A method for withering tea leaves, using withering equipment including a fan (2), a temperature sensor (3), a control box (5), a heating tube (7), and a frame (8), wherein a perforated plate (1) is arranged in the frame (8) to form a trough, and a guide plate (4) is set below the perforated plate (1). The method includes the following steps: starting the control box (5) and measuring and determining the correspondence between the wind speed and the frequency of the fan (2) in segments; spreading the fresh tea leaves flat on the perforated plate (1), controlling the thickness of the spread tea leaves to ensure uniform spreading; setting the direction and wind speed parameters of the fan (2), and starting the fan (2) and the heating tube (7); repeating the blowing process of the fan (2) and the heating process of the heating tube (7) according to the direction and wind speed parameters set in step three until withering is completed. This achieves parameterized and precise control of the withering process.

The invention relates to an automatic comprehensive withering device for fresh tea leaves, which comprises withering equipment (1), and is characterized in that the withering equipment (1) comprises a plurality of groups of withering equipment (1) which are mutually independent and are arranged in parallel, a chain plate conveying belt (23) and a temperature control fan (10) are arranged in the withering equipment (1), and the chain plate conveying belt (23) is connected with the temperature control fan (10). A material conveying system is matched with the feeding ends of the multiple groups of withering equipment (1) which are arranged in parallel, and a two-way conveying device (4) is matched with the discharging ends of the multiple groups of withering equipment (1) which are arranged in parallel. By adopting the device, the weight change of the fresh leaves can be monitored in real time through the weighing sensor, the change of the moisture content of the fresh leaves in the withering process is controlled through the change of weight data, and accurate synchronization of time and the water loss rate is realized based on dynamic comparison and prospective adjustment of the real-time water loss rate.
