Drying fragile or friable materials in a multiple-conveyor dryer
How can you ensure your fragile or friable material is gently handled and dried to the right moisture content and final characteristics day after day, regardless of ambient or slight feed changes? This article explains how a multiple-conveyor dryer that's properly designed for your material can provide uniform drying and achieve the final characteristics you desire. The first sections cover the importance of uniform drying, how a multiple-conveyor dryer works, and how your feed material and feedrate affect uniform drying. Later sections provide information about designing a multiple-conveyor dryer for your material.
Depending on your application requirements and material, you can choose one of various continuous dryers with a range of operating characteristics to dry your material. But if your material is fragile or friable, consider using a multiple-conveyor dryer. The dryer gently handles and uniformly dries materials such as flake, crystalline, granular, caked, or extruded chemicals and pharmaceuticals, food granules and pellets, tobacco, and synthetic fibers.
