When we choose Pharmaceutical Products Double Cone Vacuum Dryer, we should pay attention to material:
1) The viscosity of the material. The viscosity of the material changes with its moisture content. The viscosity can make the material agglomerate and stick to the wall of the cylinder. After drying, it is easy to stick to the dust collector and the pipe wall. Pneumatic shock and crushing devices can be used.
2) The allowable temperature of the material. The allowable temperature is the highest temperature that the material can withstand. Exceeding this temperature will result in changes in potency, decomposition, or discoloration of the material.
Applications:
This Drying Machine is suitable for concentration, mixing and drying of powder, granular and fibrous materials in such industries as chemical industry, medicine, food, etc., and materials that require low temperature drying(such as biochemical products), and is more suitable for drying of materials that are easy to oxidize, volatize, heat sensitive materials, irritant and poisonous materials, and materials in which breaking of crystals is not allowed. The rotary cone vacuum dryer is an important industrial dryer machine, lots of customers choose it.
Principle of the double cone vacuum dryer:
• After the heat source(such as hot water, low pressure steam or heat transfer oil) is connected to the closed jacket, the heat is transferred from the inner shell to the materials to be dried.
• Driven by the power, the tank makes slow rotation and the materials in the tank are continuously mixed so as to realize the purpose of drying.
• When the materials are under vacuum, the steam pressure reduces to make the moisture(solvent) on material surtaces reach the saturation status and evaporate, and discharged and recovered timely from the vacuum pump. The moisture(solvent) inside the materials is penetrated, evaporated and discharged towards the surfaces. The three processes are carried out continuously, so that the materials are dried within a very short time.
Features:
• During oil heating, automatic constant temperature control is adopted to dry biochemical products and mineral raw materials.
Temperatures vary within the range of 20-160℃.
• The heat efficiency is 2 times higher than that of common ovens.
• Indirect heating will cause no pollution to the materials, conforming to GMP requirements. The equipment is simple to repair and operate and easy to clean.
