Cone vacuum dryer is an efficient and enclosed drying equipment widely used in industries such as pharmaceuticals, chemicals, and food for drying, mixing, and cooling heat sensitive, viscous, paste like, or powdery materials. Its core design is a conical structure, combined with vacuum environment and stirring function, to ensure rapid and uniform drying of materials under low temperature and low pressure conditions.

Main structural components

1. Conical jacket container:

-The conical design increases the heat transfer area, and hot water, steam, or thermal oil is introduced into the jacket to provide uniform heating/cooling.

2. Mixing system:

-Internally equipped with a spiral or blade stirrer, low-speed operation prevents material agglomeration and promotes heat transfer and mixing.

3. Vacuum system:

-Reduce the pressure in the drying chamber through a vacuum pump, accelerate water evaporation, and avoid high temperature damage to the active ingredients of the material.

4. Drive device * *:

-Variable frequency motor controls the mixing speed to meet the process requirements of different materials.

5. Incoming and outgoing material system:

-The bottom adopts pneumatic or manual discharge valve, with good sealing and easy aseptic operation.

Advantages and Features

1. Efficient drying*

-Vacuum low-temperature drying: Under low pressure, the boiling point of water decreases, and the material can be quickly dehydrated at 40-80 ℃, suitable for thermosensitive substances such as vitamins and enzyme preparations.

-Large heat transfer area: conical structure+jacket design, heat transfer efficiency is 30%~50% higher than traditional ovens.

2. Drying uniformity

-The mixer and scraper operate synchronously to eliminate dead corners, especially suitable for high viscosity materials (such as traditional Chinese medicine extracts and polymer slurries), and the humidity deviation can be controlled within ± 1%.

3. Wide applicability

-It can handle various forms of materials such as paste, paste, and powder, and is suitable for multi process integration such as drying, reaction, sterilization, etc., such as raw material crystallization and food additive granulation.

4. Energy conservation and environmental protection

-The vacuum environment reduces the heat loss, saving about 20%~30% energy compared with the spray dryer; The closed system avoids dust leakage and complies with GMP and environmental requirements.

5. Aseptic operation

-Fully enclosed structure+online cleaning (CIP) function, meeting the sterile production standards of the pharmaceutical industry, such as the drying of antibiotics and freeze-dried powder injections.

6. Anti caking and oxygen control

-The vacuum environment prevents material oxidation and deterioration, the stirring system avoids clumping, and ensures the looseness of the finished product (such as dyes and pigments that do not need to be crushed after drying).

7. Intelligent operation

-Equipped with PLC control system, programmable temperature, vacuum degree, stirring speed parameters, real-time monitoring of drying curve, data recording meets FDA audit tracking requirements.

Application scenarios

-Pharmaceutical industry: raw material drying, particle preparation, sterile powder processing.

-Food industry: Low moisture drying of fruit and vegetable powders, seasonings, and probiotics.

-Chemical industry: Low temperature dehydration of catalysts, dyes, and polymer materials.

-New energy materials: solvent recovery and drying of lithium battery positive electrode slurry.
