Paddle Dryer

Working Principle: 
As shown in the chart, in the jacket shell body there are two parallel shafts which have interleaved paddles. Each shaft has several hollow fan-shaped paddles which interleave with a certain spacing. There are two kinds of paddles: feed shear plane and return shear plane, the shaft rotates at low speed. A heating medium enters the hollow rotary shafts and paddles through a universal revolving joint. After heat transfer and drying, it is discharged through the revolving joint. The material is continuously fed into the equipment, next it is agitated and mixed near the paddles. At the same time, the material is gradually dried by the heat conduction of paddle and jacket. The height of overflow weir can be changed to adjust residence time. In addition, steam produced in the drying process is discharged through the escape hole with trace amount of air. 



Characteristics: 
1. It adopts conduction type of heat transfer, the heat transfer efficiency is high. 
2. The self-cleaning function of the heat transfer surface is good. 
3. The product quality is stable. 
4. The material loss is small, the product recovery rate is high. 
5. The material adaptability is broad, the product is dried evenly. 
6. It can combine drying and cooling together. 
7. The equipment with compact structure occupies small area. 
8. The design is unique, and maintenance of the equipment is easy. 


Applied Medium:

Steam, hot water, hot oil, cooling water, all kinds of cooling media.

MAIN INTRODUCTION

Paddle dryer is an indirect conduction heating type drying device, which is suitable for processing materials with good thermal stability such as paste, powder and granular. After special configuration, it can be used for processing heat sensitive materials, materials that need recover solvents during drying process and materials that need to be dried under rough vacuum. At the same time, paddle dryer can also be used for cooling of powder and granular materials and cooling and crystallization of some special materials by injecting cooling medium. It also can inject heating medium for heating materials and reactor to be heated.
