DryBand Vacuum Belt Dryer
Design and Functionality The DryBand is especially suitable for products which are sticky, high viscous and/or hygroscopic as well as for the products that are sensitive to thermal stress. Liquid products are uniformly distributed on the belts with swivel feeders and are conveyed through the dryer on parallel operating belts for specified residence time. Contact heating plates underneath the belts provide desired heat through individually controlled heating zones. Optional radiant heating plates (patented) bring additional energy into the product from the top, to accelerate drying as well as for controlled maillard reaction. In the last zone, the product cools down below the glass transition temperature and becomes brittle. At the end of the belt, the dried Technical data product cake is cut by guillotine and crushed into small pieces using a crusher or cribbler®.
