Abstract
The objective of this research is to investigate the performance of drier with next generation engineering plastic pellet. This drier is made by Tokki Co.,Ltd. The previous drier was the cyclone type drier. The cyclone type drier is maintained the momentum balance of impeller regularly. These maintenances are very expensive and need long time. The first unit of engineering plastic drier which was more efficient than a cyclone type was developed. However, the first unit was a high price. We grasp performance of the first unit and aimed at the cost price reduction. As a result of grasped performance, we understand that we may change the blower motor from 3.7kW to 2.2kW, and it is succeeded by cost price reduction with maintaining performance.
