The Bi-conical Rotary Vacuum Dryer consists of a bi-conical rotating drum. In a vacuum state, heat is transferred to the jacket by circulating thermal oil or hot water, with heat exchanging through the drum's inner wall with the wet material. The steam or other gases evaporated from the wet material are then extracted through the vacuum pump via the vacuum exhaust pipe. Due to the vacuum inside the drum and the continuous up-and-down, inside-out rotation of the drum, the drying speed of the material is accelerated, enhancing the drying rate to achieve uniform drying.

Features

The Bi-conical Rotating Vacuum Dryer is a new type of dryer that integrates mixing and drying. It is equipped with a condenser, vacuum pump, and dryer to form a vacuum drying system. (The condenser is not required if solvent recovery is not needed.) The machine is designed with advanced technology, featuring a simple internal structure, easy cleaning, and complete discharge of materials. It simplifies operation, reduces labor intensity, and improves the working environment. Additionally, as the container rotates, the material also rotates, but does not accumulate on the wall, resulting in a high heat transfer coefficient and rapid drying speed. This not only saves energy but also ensures uniform and thorough drying of the material, leading to high quality. It is widely applicable in the drying processes of industries such as pharmaceuticals, chemicals, food, and dyes.

Application Scope

This machine is suitable for vacuum drying and mixing of powdered and granular materials in industries such as pharmaceuticals, food, and chemicals, particularly for drying that meets the following requirements:

No tolerance for thermosensitive materials that cannot withstand high temperatures.

Materials for solvent and toxic gas recovery required

Easily oxidizable, hazardous material

Material with crystalline requirements

Material with extremely low residual volatile content required.
