Double Cone Rotary Vacuum

Double Cone Rotary Vacuum is a drying equipment that integrates mixing and vacuum drying. The process of vacuum drying is to place the dried material in a sealed cylinder, and use a vacuum system to vacuum while continuously heating the dried material. This allows the water inside the material to diffuse to the surface through pressure or concentration differences. Water molecules (or other non condensable gases) gain sufficient kinetic energy on the surface of the material, and after overcoming the mutual attraction between molecules, they diffuse to the low-pressure space of the vacuum chamber, The separation from the solid is completed by being pumped away by a vacuum pump.

(1) During the vacuum drying process, the pressure inside the cylinder is always lower than atmospheric pressure, with a small number of gas molecules, low density, and low oxygen content, which can dry easily oxidized drugs and reduce the chances of material contamination.
(2) Due to the direct ratio between temperature and steam pressure during the vaporization process of moisture content, during vacuum drying, the moisture content in the material can vaporize at low temperatures, achieving low-temperature drying, which is particularly suitable for the production of drugs with heat sensitive materials.
(3) Vacuum drying can eliminate the surface hardening phenomenon that is easy to occur during atmospheric hot air drying. This is because the pressure difference between the inside and surface of the vacuum dried material is large, and under the pressure gradient, water quickly moves towards the surface without surface hardening.
(4) Due to the small temperature gradient between the inside and outside of the material during vacuum drying, the moisture can be moved and collected independently due to reverse osmosis, effectively overcoming the dispersion phenomenon caused by hot air drying.

Double Cone Rotary Vacuum is suitable for the vacuum drying of powder and granular materials in medicine, food, chemical industry and other industries, especially for the drying of the following materials: materials with heat sensitivity, easy oxidation, crystals that are not allowed to be damaged, materials with recycled solvents, and materials with strong stimulation and toxicity.
