Overview:
The Double-Cone Rotary Vacuum Dryer is a versatile drying equipment that combines mixing and vacuum drying processes. During vacuum drying, the material is placed in a sealed cylinder where it is continuously heated while the vacuum system removes moisture. This is achieved by creating a pressure difference, which allows water molecules to diffuse to the surface and be removed by a vacuum pump, completing the separation from the solid material.
Features:
- During vacuum drying, the pressure inside the cylinder is consistently lower than atmospheric pressure, reducing the number of gas molecules, density, and oxygen content. This environment is ideal for drying easily oxidized medicines and significantly reduces the risk of bacterial contamination.
- The relationship between vaporization temperature and steam pressure enables moisture to vaporize at low temperatures during vacuum drying, making it perfect for producing heat-sensitive pharmaceutical materials.
- Vacuum drying eliminates surface hardening, a common issue caused by large pressure differences between the interior and surface of drying materials, ensuring no surface hardening occurs.
- The minimal temperature gradient during vacuum drying facilitates reverse osmosis, allowing moisture to move and be collected efficiently. This process effectively prevents the loss phenomenon commonly encountered in hot air drying.

Principle:
The Double-Cone Dryer features a double-cone rotary tank. Under vacuum conditions, steam or hot water is introduced into the jacket to heat the tank. The heat-absorbed moisture is evaporated and pumped out through the vacuum exhaust pipe by the vacuum pump. The vacuum state of the tank, combined with its rotation, ensures the material moves consistently, accelerating drying speed, improving efficiency, and achieving uniform drying.
Impact Factors:
- The overall condition of the dried material-including its shape, size, and stacking method-as well as its moisture content, density, viscosity, and other properties, play a crucial role in the drying process. Furthermore, accelerating the vacuum drying speed can be achieved by elevating the initial temperature of the material, conducting pre-treatments post-vacuum filtration, and minimizing the moisture content.
- The degree of vacuum significantly impacts the vaporization of water at lower temperatures. However, while a higher vacuum degree promotes vaporization, it can hinder heat conduction, thus affecting the heating efficiency of the materials. To optimize drying speed, the vacuum degree must be tailored to the specific characteristics of the materials. Generally, the vacuum should not be lower than 104Pa.
Applicable Scope:
Our High-Tech Double Cone Rotary Vacuum Dryer is ideal for vacuum drying and mixing powder and granular materials across various industries, including pharmaceuticals, food, and chemicals. It is especially suited for materials with the following specific requirements:
1. Materials sensitive to high temperatures and thermosensitive substances;
2. Materials prone to oxidation and hazardous reactions;
3. Materials necessitating the recovery of solvents and toxic gases;
4. Materials requiring extremely low residual volatile content;
5. Materials that need thorough and uniform mixing.
