These images show Coomtech's pilot plant in Adlington, in the north of England. Wet material is fed into the system via an augur, and enters the drying line through a rotary valve, becoming entrained in an airflow. The drying line contains drying cartridges, which are the core components of the system. In these cartridges the material passes through a sequence of air knives where high-velocity, closely controlled contra-air flows strip the moisture from the surface of the material. The dried material then passes to a cyclone, where the moist air is vented and the dry air dropped into storage.
