Scope of application and advantages of the drying system
The MASS magazine continuous dryer MT is designed for heating ceramics and drying pastes. The products to be dried are conveyed within the drying system in a customer magazine and transported through the system in stacks. The heating process takes place via convection heat. Multiple heating zones can be used to set the desired temperature profile in the drying system. In order to be able to extract even high solvent contents, the exhaust air volumes at each heating zone can be adjusted via throttle valves. The good insulation and well thought-out design of the drying system keeps energy consumption and heat losses low.
Mode of operation and structure of the drying system
The heating system of the drying system consists of at least two heating zones, each of which is controlled separately. From each zone, supply and exhaust air can be adjusted via throttle valves to effectively extract any escaping solvents and adjust the fresh air balance. For applications with low solvent leakage, the drying system can also be operated with very low air exchange.
The heating zones of the drying system consist of air ducts equipped with perforated plates on the blowing and suction side. To ensure a uniform air flow, the air ducts are adapted to the passage height.
Heating registers and recirculation fans are installed above the air ducts. To the outside, the heating zones are effectively insulated so that energy consumption can be kept low and heating up of the production hall is avoided.
The heating zones are sealed off from the inlet and outlet with a double glass door. It opens and closes each time the tray stacks are moved in or out. Thus, heat loss is also low at this point.
