Abstract: The feature of pulse tube drier and cyclone drier was analyzed. Accoding to the demand of production,a new drier system to combine pulse air convection drier with cyclone drier was developed. Practice proved that the new system possess showed many advantages over either of the two driers used alone. The new drying system possessed high mass transfer efficency and heat efficency. It fitted to dry every single powder and grain material of low stiky matter. It has been used for drying monosodium glutamate powder in factory.
