Overview:
The Precision Double Cone Rotary Vacuum Dryer is a sophisticated drying equipment that seamlessly merges mixing and vacuum drying processes. During vacuum drying, the material placed in a sealed cylinder is continuously heated as a vacuum system pumps out the air. This causes moisture within the material to move to the surface via pressure or concentration differences. Subsequently, water molecules acquire sufficient kinetic energy to overcome molecular attractions and diffuse into the low-pressure space of the vacuum chamber, where they are removed by the vacuum pump, ensuring an efficient separation from the solid.
Features:
- In the vacuum drying process, the pressure within the cylinder remains consistently lower than atmospheric pressure, resulting in fewer gas molecules, lower density, and reduced oxygen content. This makes it ideal for drying easily oxidizable substances, thereby minimizing the risk of bacterial contamination.
- Since the temperature required for moisture vaporization is directly proportional to steam pressure, vacuum drying facilitates moisture vaporization at lower temperatures. This makes it particularly suitable for drying heat-sensitive pharmaceutical materials.
- Vacuum drying effectively prevents surface hardening, a common issue caused by significant pressure differences between the interior and surface of the material. With vacuum drying, this problem is eradicated.
- Due to the minimal temperature gradient between the interior and exterior of the material during vacuum drying, moisture migrates via reverse osmosis, effectively preventing the losses typically associated with hot air drying.

Principle:
The double-cone dryer features a rotating double-cone tank. Under vacuum conditions, steam or hot water is introduced into the jacket to heat the tank. As the wet material absorbs heat, the water vapor generated is extracted through the vacuum exhaust pipe by the vacuum pump. The vacuum state within the tank combined with its rotation ensures the material constantly moves, enhancing drying speed, improving efficiency, and achieving uniform drying.
Impact Factors:
- The final condition of the dried material, such as its shape, size, stacking method, moisture content, density, viscosity, and other inherent properties, plays a crucial role in the efficiency of vacuum drying. Moreover, the vacuum drying speed can be significantly enhanced by elevating the initial temperature of the material, pre-treating it after vacuum filtration, and minimizing its moisture content.
- A higher vacuum degree facilitates the vaporization of water at lower temperatures, yet it can hinder heat conduction, thereby affecting the material's heating efficiency. To optimize the drying speed, the vacuum degree should be adjusted according to the material's characteristics. Generally, the vacuum should not fall below 104Pa.
Applicable Scope:
This machine excels in vacuum drying and mixing of powder and granular materials across industries such as pharmaceuticals, food, and chemicals. It is particularly adept for materials with the following requirements:
1. Ideal for thermosensitive materials that cannot endure high temperatures;
2. Suitable for materials prone to oxidation and hazardous substances;
3. Essential for materials requiring solvent recovery and the safe handling of toxic gases;
4. Perfect for materials demanding extremely low residual volatile content;
5. Ensures sufficient and uniform mixing for consistent material quality.
