Sludge Stirring Rotary Vacuum Drying Machine 1800L With Harrow Paddle
1800L Working Volume Sludge Stirring Harrow Paddle Rotary Vacuum Dryer
vacuum rake dryer is a new type drying machine ,which is designed with the combination of oar blade dryer heat drying principle, with a higher drying efficiency, for a variety of raw materials.
The inner equipped oar blade and screw with continuous ,axial and radial mixing of raw materials ,make the materials to be dried more evenly.With applied both oar blade and screw, when the raw materials were turned over by mixing blades, they speed up the materials contact with heating surface of the dryer,so heat transfer rate is increased,and is conducive to moisture evaporation.
Product Structure
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.
Product Structure Features
1. Being installed stirrer in the machine, it makes raw material form the state of continuous circle inside the body, so heating uniformity of raw material is raised greatly.
2. Being installed stirrer in the machine, slurry and paste shape material can be dried easily.
3. Special design for discharging port, make better sealing and less material accumulation, discharge is easy.
4. There are two seal model, mechanical seal and packing seal. The design supply good seal and long life.
5. The special techniques of shaft and rake support high strength and concentric.
6. The medium in shaft and vibration adding equipment will be equipped by requirement
7. Use different filter form according to different material.
Product Application
The following raw materials from pharmaceutical industry, foodstuff industry, chemical industry and so on can be dried.
- Pulpiness, paste-like mixture or powder raw material.
- Thermal sensitive raw material having the requirement to dry at lower temperature.
- Raw materials that are easy to oxidize or explode and have strong irritative or toxic.
- Raw materials that need to recover solvent.
