Single Paddle Dryer (SPD)
Product Outline
Single Paddle Dryer is a single shaft indirect heating dryer designed to process powders with relatively weak agglomerate force and high fluidity. Disc-type wings designed for single shaft dryer provide high partition efficiency and ensure excellent piston flow. By optimized disc pitch in the single shaft dryer, Single Paddle Dryer has a heat transfer area per volume equivalent to that of twin shaft paddle dryer. This dryer is more cost-effective compared with a paddle dryer as it is single shaft with less sealing sections than a paddle dryer.
Features
- It has a large heat transfer area per unit volume. It secures a heat transfer area equivalent to that of a paddle dryer by optimizing the shape of disk or pitch. This allows to take up less space for equipment installation.
- It is easy to control throughput. As unnotched disk-type wings are adopted, plates that enhance transportation capacity are utilized. Therefore, the throughput of material being processed is easily controlled by changing rotation speed of the shaft.
- Low-speed shaft rotation eliminates damage to particles. The shaft of a single paddle dryer rotates at a low speed of 5-30min-1. Therefore, damage to the particles and abrasion to the equipment are kept to a minimum.
