The continuous dryer operates by pulling hot air through one or two product beds which are each variable in depth. New product is continuously fed in through the inlet valve, while the Swivel Valve discharger ensures smooth discharging of dried product to the next drying deck or into the hopper. Bridging of the product bed is avoided by gently lifting the product bed before discharging.
The discharge system is triggered by level or temperature sensor and driven by hydraulic cylinder and power pack. Open and closed positions of the discharger can be adjusted either manually or remotely by controller or PLC.
Dryer air is partially recirculated back into the heater for maximum energy efficiency and only a limited volume of air is exhausted at a high relative humidity.
