Introduction
Double cone rotary vacuum dryer is an efficient equipment that integrates drying and mixing functions, widely used in industries such as pharmaceuticals, chemicals, food, dyes, etc. Its unique double cone structure design enables uniform mixing of materials through rotation in a vacuum state, while removing moisture or solvents through jacket heating or vacuum drying, significantly improving production efficiency.
Working principle and structural design
The main body of the double cone drying mixer equipment is welded from two conical cylinders, connected by a cylindrical section in the middle, forming a symmetrical structure as a whole. During operation, the motor drives the cone to rotate at a speed of 5-20 rpm, and the material continuously rolls, convects, and shears along the cone wall under the action of gravity, achieving uniform mixing in three-dimensional space. At the same time, hot water, steam, or thermal oil is introduced into the jacket, and heat is conducted to the material through the cylinder wall; If deep drying is required, the vacuum pump can be turned on to extract air from the cylinder, reducing the boiling point to accelerate solvent evaporation, especially suitable for low-temperature drying of thermosensitive materials.
Key structural components include
1. Double cone container: made of stainless steel (such as 304 or 316L), with mirror finish inside the tank, Ra ≤ 0.4 to reduce adhesion, and polished outer surface. The volume ranges from 50L to 5000L.
2. Drive system: composed of a motor, gear set, and supporting bearings to ensure smooth rotation. Equipped with variable frequency speed regulation to adapt to different material speed adjustments.
3. Vacuum system: includes a vacuum pump, condenser, and filter, used to maintain a negative pressure environment, and the solvent can be recycled.
4. Heating system: The jacket design is coordinated with the circulation of heat me.
