Application

The vacuum rake drying machine is widely used in pharmaceutical, chemical, food, dyes, powder metallurgy and other industries powder, granular (including crystal) material drying. Particularly suitable for dry heat-sensitive materials.


Structure Description

The dryer vacuum degree can reach above -0.092Mpa, the solvent (including water)of a variety of materials can be quickly evaporated in the vacuum and low temperature conditions, to get the purpose of accelerating drying. There is a stirrer with paddle remove materials on hot surface and move in the container to form cycle flow. The evaporated moisture will be pumped by vacuum pump.  


The dryer body was in cylinder shape. The configuration include material inlet, vacuum entrance and steam inlet and outlet ( the upper part was steam inlet , the lower part was steam outlet when heating source was steam), in the lower part there are same size of the nozzle. The body is divided into three layers, the middle jacket heating medium can be steam, insulation layer for the ultra-fine glass wool, good insulation. The material was turning over and over through the rake teeth and being heated by the inner wall , the middle jacket transfer the heat and increase the drying speed in the vacuum status, avoid the raw material surface of being changed yellow phenomenon., reduce working time and save cost. Especially suitable for the heat-sensitive materials.



Features

The vacuum rake drying machine is simple to operate, easy control the material, greatly reducing the labor intensity of workers, also reduce the material pollution in the drying process at the same time.

1.The reducer: the reducer installed in the right side of the machine. The motor was driven by the pulley and the V-belt to the gear unit, the spindle rotation to the rake teeth, and finally the cylinder rotated and get speed of 6~ 10 r / min.

2.The motor base device: The motor was mounted on the right side of the activity board, can be adjusted up and down, so that the V-belt tight fit.

3.Electrical control device (EU standard): All the electrical control, buttons, lights are installed in the control box, the operation can be controlled based on the panel text instructions. The positive and the reversing rotating direction of the stirring shaft can be adjusted according to the characteristics of the material. Generally, it can be controlled in about 5 minutes (ie, after stopping for 5 minutes, then reversing for 5 minutes).

4.Vacuum tube: Used to extract the cylinder evaporation’s solvent (or water) . In the inlet side with a filter, should be covered with filter cloth to prevent the material out.

5.Sealed structure: The spindle at both ends are sealed with PTFE , sealed in a vacuum to achieve a good sealing effect.

6.The mixing shaft with stainless steel thick-walled tube, rake arm rake teeth are made of stainless steel seamless stainless steel plate. Rake board was PTFE plated, scraping the sticky material. 

Applicable Materials

Slurry: all kinds of pigments, muddy materials/soda detergent, alkali/ash, etc.

Paste: Filtered/starch, dye/clay, etc.

The following 100 items: Centrifuge filters and / pigments, clay / cement, etc.
