Equipment overview of rotary vacuum dryer

Rotary Vacuum Dryer is one of the main products of Griffin Co., and it is a commonly used Drying Equipment. This Dryer adopts automatic constant temperature control, the temperature can be controlled between 20-160oc, and the thermal efficiency is high, and the efficiency is 2 times higher than that of ordinary dryers. At the same time, the rotary vacuum dryer adopts indirect heating, the material will not be polluted, and it meets the requirements of GMP. The device is easy to service and easy to clean.

When the rotary vacuum dryer is drying, the drying tank is in a vacuum state. With the low-speed rotation of the tank, the material moves up and down in the tank to generate steam, and the water vapor is continuously discharged through the vacuum pipeline to achieve the purpose of drying the material. At the same time, thermal energy is transferred to the closed intermediate layer, and the heat is transferred to the dry material through the inner shell. Under the action of power, the tank body rotates slowly, and the materials in the tank are continuously mixed to achieve the purpose of strengthening drying.

Rotary vacuum dryer is mainly used for vacuum drying and mixing of powdery granular materials in pharmaceutical, food, chemical and other industries. It is more suitable for oxidizing, volatile, sensitive, strongly irritating and toxic substances, and it is not allowed to destroy crystalline materials.

The rotary vacuum drying system is mainly composed of rotary vacuum dryer, condenser, vacuum cleaner, vacuum extraction system, heating system, cooling system, electrical control system, etc. Rotary vacuum dryers are shaped like olives with lids on both ends and two shafts in the middle to support the body. The body has a collet for heating. When drying, the tube body can be rotated to move the material in the tank, which overcomes the disadvantage that the material in the vacuum furnace is mainly heated by the heating tube and the thermal efficiency is low.

From a brief overview of the rotary vacuum dryer, we can roughly understand the application industry of the rotary vacuum dryer, the characteristics of the equipment, and a principle of the equipment, which provides a basis for our operation and use.
