Based on the manufacture technology of vacuum dryers in China, the rake type vacuum dryer is our improved products for drying materials shaped like slurry, paste, grain, power and fibre.

 

The drive system adopts column gear reducer which performs firm and wear well. The driving shaft is stainless steel thickened solid type. The rake teeth is made of high strength stainless steel, which guarantees the stable operation under all kind of odious conditions. Inside the shell can be added two or four impact rods for the purpose of high speed drying and smashing. The heating medium can be steam, heat conducting oil and hot water.

 

Application range:

 

It is especially used to dry materials that are heat sensitive, oxidable, and easy to harden and also materials whose vented steam during drying need to be reclaimed. The material is of powder shape after drying, so it is suitable for drying materials whose finished products are powder shaped. The materials can be directly packed after drying, and they don't need to be smashed. The feeded material for rake type vacuum dryer can contain 90% water. The materials to be dried can be shaped like slurry, grease, grain, powder, or fiber. Only 1% or even 0.5% water can be left after drying.The vacuum dryer is now widely used in the production of solid alcohol,sodium(kalium).

 

Characteristics:

 

1. Wide application range, high drying speed. Because the rake vacuum pump use jacket to heat and high vacuum to vent gases. So it can almost apply for all materials with different quality and different shape. It is especially suitable for flamable and oxidable materials.

 

2. High quality products. The rake teeth turns in two directions constantly, and the material is well mixed.

 

3. Small steam consumption.

 

4. Easy operation. It can be used to reclaim volatilizable gases, and reduce environment pollution.
