Overview:
Double-cone rotary vacuum drier is a kind of drying equipment which integrates mixing and vacuum drying. The process of vacuum drying is that the dried material is placed in a sealed cylinder, and the dried material is continuously heated while the vacuum system is used to pump the vacuum, so that the moisture inside the material diffuses to the surface through the pressure difference or the concentration difference, the water molecules (or other non-condensable gases) obtain enough kinetic energy on the surface of the material, after overcoming the mutual attraction between the molecules, they diffuse to the low pressure space of the vacuum chamber, and are removed by the vacuum pump to complete the separation from the solid.
Features:
- During the vacuum drying process, the pressure in the cylinder is always lower than the atmospheric pressure, the gas molecule number is small, the density is low, the oxygen content is low, therefore can dry the easy oxidation medicine, reduces the material the opportunity which infects the bacterium.
- Because moisture in the vaporization process temperature and steam pressure is proportional, so when the vacuum drying, the moisture in the material can be vaporized at low temperature to achieve low temperature drying, especially suitable for the production of heat-sensitive materials of pharmaceuticals.
- Vacuum drying can eliminate the surface hardening phenomenon, which is caused by the large pressure difference between the inside and the surface of the vacuum drying material, no surface hardening will occur.
- Because of the small temperature gradient between the inside and outside of the material during vacuum drying, the moisture can be moved and collected by itself due to reverse osmosis, thus effectively overcoming the loss phenomenon caused by hot air drying.

Principle:
The double-cone drier is a double-cone rotary tank. Under vacuum, steam or hot water is introduced into the jacket to heat the tank. The water vapor which evaporates after the wet material absorbs heat is pumped out through the vacuum exhaust pipe through the vacuum pump. Because the tank is in the vacuum state, and the rotation of the tank makes the material move up and down, inside and outside constantly, so it speeds up the drying speed of the material, improves the drying efficiency, and achieves the goal of uniform drying.
Impact Factors:
- The condition of the dried material (such as the material shape, size, stacking method) , the material itself moisture content, density, viscosity and other properties. In addition, the vacuum drying speed can be increased by increasing the initial temperature of the material, pre-treatment after vacuum filtration and reducing the moisture content of the material.
- The higher the degree of vacuum, the more beneficial to the vaporization of water at a lower temperature, but the higher the degree of vacuum is not conducive to heat conduction, affecting the heating effect of materials. In order to improve the drying speed of materials, the vacuum degree should be considered according to the characteristics of materials. In general, the vacuum should not be less than 104Pa.
Applicable Scope:
This machine is suitable for vacuum drying and mixing of powder and granular materials in industries such as medicine, food, and chemical industry, especially for materials with the following requirements:
1. Cannot accept high-temperature thermosensitive materials;
2. Materials that are prone to oxidation and hazardous;
3. Materials that require the recovery of solvents and toxic gases;
4. Require materials with extremely low residual volatile content;
5. Require sufficient and uniform mixing of materials.
