This series ventilation sterilizer adopts mixed clean steam and air as sterilization medium, equipment and product pressure balance and back pressure protection can be well controlled by this way, so this equipment is widely used for the items that need to keep shape and saled in the same time of sterilization. force caonvection fan and air guide plate structure make the chamber non saturated steam well mixed to ensure the sterilization temperature evenness. and the equipment is equipped with cooling coil. product cooling and drying is achieved by the condensation of the mixed gas inside the chamber through getting the cooling water into the coil. product evaporates in the same time, to realize the purpose of cooling and drying finally.the machine could also be equipped with hot air drying function for some products that have high requirements for the drying effect.
