Vacuum Harrow Dryer

The vacuum rake dryer is a kind of indirect heating of thermal conductivity, and a horizontal stirring dryer. The blade of the horizontal rake mixer in the dryer is made of the seamless tube of the cast steel or the thick wall, installed on the round spindle, half of the leaves direction to the left, and the other half to the right. The speed of the shaft is 7 to 8r/min. It is driven by a transmission motor with a speeding machine. At the same time, the automatic steering is set to change the rotation direction of the mixer every 5 to 8 minutes.
The vacuum rake dryer is mainly used for explosive, oxidation, and dried materials. Operation under high vacuum, the solvent boiling point is reduced, and at the same time isolation of the air, avoiding oxidation and overheating and deterioration during the drying process of the material.

Principles of vacuum rake dryers
Add in the middle of the dry material from the middle of the shell. With the continuous rotating rake teeth, when the material is in contact with the shell wall, the surface is continuously updated. The water is removed in time by the vacuum pump. The machine can also use the mezzanine and rake teeth at the same time.
Due to the high vacuum of operation, the pressure of water vapor on the surface of dry materials is much greater than the water vapor pressure in the evaporation space in the dry case body, which is conducive to the discharge of the internal and surface moisture inside and surface moisture, which is conducive to the moisture molecular movement of dry materials. To achieve the purpose of dryness.

characteristics
1. Strong adaptability and wide application: Due to the heating and high vacuum exhaust of the rake vacuum dryer, almost all materials of different properties and states are adapted, especially adapting to explosive, oxidation, paste -like creamy, creamy, creamy, creamy The drying of the material;
2. Steam consumption: Because the vacuum rake dryer is used to use the steam to use the steam to use the fixture, the use of the submarine heat heating material, the steam consumption per kilogram of finished products is small, and generally evaporates 1kg of water to consume 1.3 ～ 1.8kg;
3. Easy to operate: The vacuum rake dryer is easy to operate, less member, and low labor intensity. The loss of material restrictions has decreased and improved environmental hygiene.
4. Good product quality: During the drying process, the rake teeth are constantly turning forward and reversed, stirred by dry materials to avoid overheating of the material, and the water is easy to renew. Due to the fine grain size, it can be packaged without crushing;
5. Without air intervention, the condenser is very small, which is convenient for recycling material solvents;
6. According to the different characteristics and requirements of dry materials, the sealing system of the dryer can choose two types: filler sealing and mechanical sealing. The special design guarantees the sealing and service life;
