In industries such as pharmaceuticals, chemicals, and food, the drying treatment of heat sensitive and easily oxidizable materials requires a balance between efficiency and purity,Double cone rotary vacuum dryerWith its low-temperature drying and three-dimensional mixing ability in a vacuum environment, it has become an ideal equipment for drying powder particle materials and is widely used in production scenarios that require uniform drying and avoid pollution. ​

The pharmaceutical industry is the core application area of vacuum dryers. In the drying of antibiotic raw materials, the material needs to be dehydrated below 60 ℃. The equipment extracts low boiling point water through vacuum filtration to vaporize the water at 40-50 ℃, avoiding the degradation of active ingredients caused by high temperature. The purity of the finished product is maintained at 99.5% or above. When processing traditional Chinese medicine extract powder, the 360 ° rotation of the double cone cylinder continuously flips and mixes the materials, eliminating local clumps and achieving a drying uniformity of 98%, which is 40% more efficient than static vacuum drying. The inner wall is designed with mirror polishing (Ra ≤ 0.8 μ m) to avoid material residue and meet GMP requirements for equipment cleanliness. After each batch of production, it can be quickly cleaned through CIP online cleaning system to reduce the risk of cross contamination. ​

In fine chemical production, this equipment is suitable for the drying needs of multiple varieties and small batches. When drying dye intermediates, the vacuum environment isolates the air to prevent material oxidation and discoloration, thereby improving the color fastness of the product by 1-2 levels; When processing catalyst powder, low-temperature drying can retain its active components and control the catalytic efficiency loss rate within 5%. For toxic or irritating materials, the double cone sealing structure (using mechanical or magnetic seals) can prevent dust leakage, and the workshop dust concentration is controlled below 0.5mg/m ³ to ensure operational safety. The capacity of the equipment can be customized (50-5000L) to meet different scale requirements from laboratory trials to industrial production. ​

In the production of food additives and health products, the double cone rotary vacuum dryer ensures product quality. When drying probiotic powder, the temperature is controlled at 35 ℃ under vacuum to increase the survival rate of live bacteria from 60% in conventional drying to over 90%; When processing protein powder, surface hardening is avoided by rotary stirring, resulting in a 20% increase in solubility of the finished product and no precipitation during brewing. Its all stainless steel material (316L) contacts the material, which is resistant to acid and alkali corrosion and meets food grade requirements. The dried material can be directly used for subsequent packaging without the need for secondary treatment. Compared to hot air drying, it reduces energy consumption by 30-50%, making it particularly suitable for cost control in mass production. ​
