9. The traditional drying equipment directly discharges the high-temperature and high-humidity waste gas into the outside air, so that not only can the heat be directly lost and not reused, but also the evaporated water vapor is directly discharged into the air and cannot be collected. The moisture evaporated from the materials such as tea, chrysanthemum, rose and the like in the drying process contains some components of the tea, chrysanthemum, rose and the like, and is a raw material for manufacturing other products, and waste can be caused by direct discharge, but if the materials are collected by special condensing equipment, firstly, the problems of high equipment cost and high use cost of the condensing equipment are solved, and secondly, the amount of tea and chrysanthemum produced by a single farmer is low, so that the benefit is not obvious. The drying equipment perfectly solves the problems, the evaporator component in the air energy heating system can well collect moisture evaporated by drying for condensation collection, the evaporator belongs to a part of air energy heating, the equipment is not additionally increased, the energy consumption is not additionally increased, the waste heat which is originally required to be discharged can be recycled, the heat is recycled, the energy is saved, and the condensed water can be collected along the way. The individual farmers collect the evaporated water without increasing the collection cost, and then arrange special persons to go to the gate to recycle the water one by one, so that the condensed water is collected at extremely low cost, and partial income can be increased for the farmers, thereby achieving four purposes at one time.
