The double cone rotary vacuum dryer uses a double cone cylinder as its core to achieve uniform mixing of materials through cylinder rotation, and is equipped with a vacuum system to reduce drying temperature. It is suitable for drying materials that are temperature sensitive, prone to clumping, or require solvent recovery, and can reduce material deterioration and loss. It is a commonly used equipment for batch production in multiple industries.
1、 Core working characteristics of double cone rotary vacuum dryer
1. Low temperature drying suitable for thermosensitive materials
The equipment relies on a vacuum environment to reduce the boiling point of materials, and the drying temperature can be controlled within a lower range to avoid the loss, discoloration, or deterioration of effective ingredients caused by high temperatures. It is especially suitable for thermosensitive materials such as traditional Chinese medicine extracts and biological preparations, ensuring the quality of dried products.
2. Heating and uniform mixing of materials
The double conical cylinder slowly rotates, driving the internal materials to constantly flip and mix, avoiding uneven heating caused by local accumulation of materials; The inner wall of the cylinder is smooth, reducing material adhesion and residual amount, while improving drying efficiency and shortening the overall drying cycle.
3. Solvent recycling and environmental friendliness
The vacuum system can extract the volatile solvent vapor from the material and recover it through a condensation device, reducing solvent waste and avoiding direct solvent discharge that may cause environmental impact. It is suitable for drying materials containing solvents such as ethanol and acetone, and meets environmental protection requirements.
4. Easy operation and maintenance
The equipment is equipped with a simple control system that can set parameters such as vacuum degree, temperature, and rotation speed. It has a high degree of automation and reduces manual intervention; The cylinder structure is easy to disassemble and clean, with no hygiene dead corners on the inner wall. During later maintenance, the replacement process of key components (such as seals and bearings) is simple, reducing operation and maintenance costs.
2、 Typical application scenarios of double cone rotary vacuum dryer
1. Pharmaceutical production field
Used for drying traditional Chinese medicine extracts, drying Western medicine raw materials, protecting the active ingredients of drugs in low-temperature environments, vacuum systems to prevent oxidation of drugs in contact with air, and easy equipment cleaning. It meets the GMP standards of the pharmaceutical industry and is suitable for the large-scale production needs of pharmaceutical companies.
2. Food processing field
Suitable for drying fruit and vegetable powder, nut products, and functional food ingredients. Low temperature drying preserves the flavor and nutrition of food, and the rotation of the cylinder reduces material clumping. After drying, the product particle size is uniform, meeting the requirements of the food industry for taste and purity.
3. In the field of chemical engineering and new materials
Used for drying fine chemical raw materials and polymer materials, it can recover solvents from materials and reduce production costs; At the same time, the vacuum environment avoids the reaction between chemical materials and air, ensuring product stability and adapting to the batch processing needs of chemical enterprises.
4. Deep processing of agricultural products
Suitable for drying dehydrated vegetables, grain products, and traditional Chinese medicinal materials. The equipment can adapt to the high moisture content characteristics of agricultural products, reduce nutrient loss through low-temperature drying, ensure uniform drying of materials through cylinder rotation, and assist agricultural product deep processing enterprises in enhancing product added value.
