Four Pass Flash Dryer is a thermo-mechanical arrangement which is used for the drying of the moist powdered substances such as sawdust, wood pulp and other substances. The multiple pass design configuration of this system makes it highly efficient and useful for completely eliminating the moisture and water present inside the raw materials. The body of the machinery is fabricated with heat resistive material to withstand impacts of hot air. It helps to enhance the quality of the wood powder to make the mixture suitable for various applications. Four Pass Flash Dryer is equipped with an induction fan which helps to collect the dried substances into a collecting tank.
