Coating machine; heat recovery; application
Coating machine will roll the base material coated with a layer of special function of glue, paint or ink, etc into the oven after drying, winding. The heat exchange core body using high temperature oven exhaust energy to preheat the air at room temperature, high temperature air oven exhaust after the first heat exchange core body and then excreted, fresh air at room temperature after the first heat exchange core body and then into the oven, the two strands of air in the heat exchange core body internal heat exchange. When the fresh air absorbs the heat of the exhaust air, the temperature will rise substantially, and the exhaust will decrease after the exchange of the fresh air heat, and then be discharged into the outdoor environment. As a result, the temperature of the fresh air will rise significantly after the heat exchange, and then heating the fresh air into the oven through the heating device can greatly reduce the energy consumption of heating the fresh air to the temperature of the oven
