Double Cone Vacuum Dryer for Heat Sensitive Materials Drying
Application
This machine is mainly used for low-temperature vacuum drying of heat-sensitive materials, easily oxidized materials, and materials with strong volatility and irritating odor in the pharmaceutical, chemical, food, and new energy industries.It is suitable for drying powdered, granular, and crystalline materials such as raw materials, traditional Chinese medicine extracts, intermediates, food additives, and chemical powders.It can effectively maintain product stability, reduce material loss, meet GMP standards, and avoid cross-contamination during production.
Work principle
1
Vacuum negative pressure environment
The equipment works under continuous vacuum condition inside the sealed double cone tank, which lowers the boiling point of water and solvents, realizing low-temperature drying and avoiding damage to heat-sensitive materials.
2
Rotary mixing and turning
The double cone cylinder rotates slowly and continuously, making internal materials constantly flip, mix and disperse. It ensures every material particle can be evenly heated for consistent drying.
3
Vapor extraction and dehydration
Moisture and volatile solvent generated during drying are quickly extracted and discharged by the vacuum system, accelerating dehydration efficiency and shortening drying cycle.
4
Fully closed operation
The whole drying process is completed in a closed space, which effectively prevents materials from oxidation, volatilization loss and cross-contamination, and meets GMP production requirements.
Features
The inner wall of the drum is made of 304 stainless steel with a wall thickness of 6 mm. The inner surface is mirror-polished to a finish of ≤ 0.4 μm
The jacket of the equipment is made of Q235 steel with a thickness of 4 mm; the insulation shell of the drum is made of 304 stainless steel plate with a thickness of 2.5 mm, with brushed finish ≤ 0.8 μm
The frame is made of high-quality channel steel (coated with anti-corrosion material), and the frame cover is made of 304 stainless steel with a thickness of 1.5 mm.
