Dry Powder Hollow Paddle Dryer 35M2 Heat Transfer Area 15 KW

 

 

The main structure is a W-shaped shell with a jacket, which is equipped with a pair of hollow low-speed rotating hollow shafts. A number of mixing blades are welded on the shaft. The jacket and the hollow mixing blades are all equipped with heat carriers, and the two heating surfaces heat the materials at the same time. The heat carrier is usually fed from the middle of the dryer and discharged from the other side through the surface of the material layer in the agitated state.
Wedge-shaped hollow blades are densely arranged on the hollow shaft, and the thermal medium flows through the blades through the hollow shaft. The unit effective volume has a large heat transfer area. The temperature of the thermal medium ranges from - 40 ° C to 320 ° C, which can be water vapor or liquid type: such as hot water, heat transfer oil, etc. Indirect conduction heating does not carry air to take away heat. Heat is used to heat materials. The heat loss is only the heat dissipation to the environment through the insulation layer of the reactor body. The heat transfer surface of the wedge-shaped blade has the function of self-cleaning. The relative movement of the material particles and the wedge-shaped surface can wash off the attached materials on the wedge-shaped surface, so that the clean heat transfer surface is kept in motion all the time.

 

 

Low energy consumption of pulp leaf dryer: due to indirect heating, there is no large amount of air to take away heat, and the outer wall of the dryer is provided with insulation layer, which only needs 1.2kg steam to evaporate 1kg water for slurry materials.

Low cost of blade dryer system: the unit effective volume has a huge heat transfer surface, which shortens the processing time and reduces the equipment size. It greatly reduces the building area and building space.

A wide range of processing materials: using different thermal media, it can handle both heat sensitive materials and materials requiring high temperature treatment. Common media are: steam, heat transfer oil, hot water, cooling water, etc.

It can be operated continuously or intermittently, and can be used in many fields.

Small environmental pollution: do not use carrying air, dust material entrainment is small. The evaporation of solvent is very small, which is easy to handle. It can be used for contaminated materials or solvent recovery.
