Indirectly heated tube drum dryers
Indirectly heated drying systems designed to work with cogeneration systems (CHP)
Our indirectly heated tube drum dryers are specifically designed to work in combination with cogeneration systems (CHP). They function as reliable and efficient drying systems for wood flakes and other finely dissolved and free-flowing wood material, biomass products and bulk solids.
At a glance:
- Water evaporation capacity of up to 25 t/h, depending on the product
- Heated indirectly by steam, hot water or thermal oil
- Application in combination with CHP
- Product separated via discharge box
- Exhaust air filtering by means of cyclones or bag filter
Drying process
The product to be dried enters 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. The water contained in a product is then 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 discharge box and discharged through an air-tight rotary valve. Warm and moist dryer air is extracted and dedusted in cyclones or bag filters.
