The whole system of the host drying box is designed with stainless steel inner plate. The whole box is made of a thick polyurethane insulation layer, which has good thermal conductivity. The patented air distribution system was independently designed and developed, the airspeed and heat distribution in the drying room is uniform, and there is no dead angle when drying at 360 °C. time. The complete cycle is closed, and the heat is completely recovered, which can achieve zero heat loss in the drying process, and improve the energy utilization rate, which is 33% higher than the average level of the same industry.
