The GLZ series vacuum spiral belt dryer is a new generation of vacuum drying and mixing equipment developed by our factory to digest and absorb similar foreign products. The equipment integrates drying, crushing, vacuum pressure reduction, and powder mixing. It consists of a motor, reducer, frame, mechanical seal, filter, spiral belt agitator, conical cylinder with jacket heating, and discharge valve. It can achieve continuous operation in a closed manner throughout the entire process. Its drying efficiency is 3-5 times that of the SZG series double cone rotary vacuum dryer of the same specification. It is mainly used for powder drying in industries such as pharmaceuticals, chemicals, pesticides, and food.

The main body of the GLZ series vacuum ribbon dryer is vertically stationary, and the internally heated ribbon performs circular stirring and lifting motion. After the material enters the drying chamber, it is heated by the jacket and stirring ribbon, and the material is stirred in an orderly manner by the ribbon, flipping, lifting, and falling, so that the material continuously contacts the heating chamber wall for forced heat exchange. The solvent evaporated by heating is extracted in a vacuum state, thus achieving the purpose of rapid drying.

1. The parts in contact with equipment and materials are made using materials that comply with GMP requirements.

2. Top drive, the equipment has no contact with the outside air, no leakage, and no dead corners during the feeding, drying, mixing, and discharging processes.

3. The design, manufacturing, and testing of equipment chambers shall be carried out in accordance with the requirements of pressure vessels.

4. The rotating joint adopts GMP approved double end dry mechanical seals, with no foreign objects falling off.

5. The chamber and stirring blade are equipped with heating channels, and the stirring blade orderly and uniformly carries animal materials for heat exchange, with a large heating area.

6. The material does not hang on the wall or clump during the drying process.

7. The smoothness of the contact area with the material: Ra ≤ 0.4um (surface passivation or electrolytic polishing).

8. Set up an online sampler.

9. Set up a valve top dead corner blowback port.

10. Smooth operation, protecting crystal form.

11. Low operating energy consumption cost and high mixing efficiency.

12. Easy to operate and maintain.
