Overview:
The double-cone rotary vacuum dryer is an advanced drying system that combines mixing and vacuum drying into a single process. In vacuum drying, the material is enclosed in a sealed cylinder, where continuous heating and vacuum application cause moisture to migrate from the core to the surface, facilitated by pressure and concentration gradients. Once at the surface, water molecules gain enough energy to escape into the vacuum chamber, where they are efficiently removed by a vacuum pump, completing the separation from the solid.
Features:
- Throughout the vacuum drying process, the pressure remains consistently below atmospheric levels, resulting in fewer gas molecules, reduced density, and lower oxygen content. This environment is ideal for drying easily oxidizable pharmaceuticals, minimizing the risk of microbial contamination.
- The correlation between vaporization temperature and steam pressure in vacuum drying allows moisture to evaporate at substantially lower temperatures, making this technique perfect for heat-sensitive pharmaceutical production.
- Vacuum drying effectively mitigates surface hardening, a common issue in other drying methods, by balancing the internal and surface pressure differences, thus preventing any hardening from occurring.
- During vacuum drying, the minimal temperature gradient between a material's interior and exterior enables moisture to migrate and accumulate via reverse osmosis, effectively preventing the losses typically associated with hot air drying.

Principle:
The double-cone dryer comprises a dual-coned rotary tank. Within a vacuum, steam or hot water heats the tank through its jacket. The evaporated moisture from the heated material is extracted via a vacuum exhaust pipe by a vacuum pump. This vacuum environment, coupled with the tank's rotation, promotes material motion, enhancing drying speed and efficiency, and ensuring uniform drying throughout.
Impact Factors:
- The condition of the dried material-encompassing factors like shape, size, and stacking method-alongside inherent properties such as moisture content, density, and viscosity, play a crucial role in drying efficacy. Moreover, accelerating the vacuum drying speed can be achieved by modulating the initial temperature, employing vacuum filtration pre-treatments, and minimizing the material's moisture content.
- While a higher degree of vacuum amplifies the vaporization of water at reduced temperatures, it can impede heat conduction, thus influencing the material's heating efficiency. To optimize the drying speed, the vacuum level must align with the material's characteristics, generally maintaining a vacuum degree beyond 104Pa.
Applicable Scope:
This machine is adept for the vacuum drying and mixing of powders and granular materials across sectors like pharmaceuticals, food, and chemical industries, particularly catering to materials with specific requirements:
1. Materials sensitive to high temperatures should be preserved;
2. Ideal for materials prone to oxidation or presenting potential hazards;
3. Suitable for materials necessitating solvent and toxic gas recovery;
4. For materials demanding exceptionally low residual volatile content;
5. Ensures comprehensive and uniform mixing of materials.
