Hengyang indirectly heated tube drum dryers are specifically designed to work in combination with cogeneration systems (CHP). They function as reliable and efficient dryers for wood flakes,DDGS, Corn gluten feed and other finely dissolved and free-flowing wood material, biomass products and bulk solids.
A product designated for drying comes in through an air-tight rotary valve and into a rotating single-pass dryer drum with installed tube bundle. The product then flows through the heated tube bundle, which turns with the drum casing and warms the product. In doing so, the water contained in a product is evaporated into the dryer air, which is preheated by heat exchangers. At the end of the dryer drum, the dried product is separated in a drop box and discharged through an air-tight rotary valve. Warm and moist dryer air is extracted and dedusted in cyclones or bag filters.
