Calidaddelaire adopts the second-generation ultra-low temperature micro air drying technology, which utilizes the principle of low-temperature heat pump/waste heat recovery dehumidification. It uses ultra-low temperature independent air duct and micro air gradient dehumidification drying method to dehydrate and reduce the amount of wet sludge on the mesh belt. The entire system is fully enclosed in design, with dry hot air without heat loss, effectively preventing odor leakage.
