By far the largest amount of the global SAP (super absorbers) is produced in this type of machine.
The Paddle Dryer is well known for its compact construction and the consequently small need of installation space. This results from the high heat transfer coefficient and heat efficiency. These features combined with the self-cleaning effect of the paddles assure a homogeneous product for continuous and/or batch unit operations.
But the NARA paddle dryer potential still extends even further: a drying step and a reaction step or a heating process and a cooling process have been already realized in one machine. Such processes are of importance e.g. in the food industry where materials are dried and transformed into a new structure for special applications. Where materials are packed directly after drying they are cooled for operator and material protection.
The advantage is obvious - one machine substitutes two machines to save space energy and investment cost. Both types - the NPD-D and the NPD-C - are successfully operating for various substances at clients worldwide.
