Scope of application and advantages of the drying system
The MASS continuous drying system PD is designed for heating products and drying pastes and lacquers. The paternoster design saves space and offers a high degree of utilization in a comparatively small area. The drying system can be converted to other products and guarantees a stable heating process with low energy consumption.
Mode of operation and structure of the drying system
A product carrier transports the products to be dried within the drying system through the process chamber, where the heating process takes place via convection heat. The heating system of the drying system consists of a modular process zone. This stainless steel process zone is equipped with several heating zones and cooling zones. It is made of double wall and inter-insulated with high quality insulating material, which enables stable drying heat with comparatively low energy consumption.
Each heating zone of the drying system is operated separately via a separate control circuit, so that it is possible to preselect the desired set temperature for each heating circuit. In each heating zone, the air is heated by finned tube heaters and circulated by a corresponding fan. Air is discharged into the process zone via perforated plates, which ensure a uniform air flow and thus guarantee constant heat distribution. The air is also returned from the process chamber via nozzle plates, which at the same time ensure that the air is guided evenly over the heating coils. Temperature control is performed on each finned tube heater via a PID control loop. The actual value temperature is recorded by a PT-100 sensor.
