Double Cone Rotary Vacuum Dryer Descriptions
SZ Double cone rotary vacuum dryer is a new dryer that integrates mixing and drying in the one body and equips with condensor and vacuum pump. Therefore the vacuum dryer is formed(If the solvent does not recover, the condensor may be not used). The dryer is advanced in design, simple in inner structure, easy for cleaning, to discharge all raw material, convenient in operation, lowing the strength of labor and improving working environment. Meanwhile raw material is rotating accompanying with the rotating of container, the wall of container can not only save energy but also make raw material dry evenly and have good quality. It can widely apply to dry raw materials of pharmaceutical only save energy but also make raw material dry evenly and have good quality. It can widely apply too dry raw materials of pharmaceutiacl industry, chemical industry, foodstuff industry, dyestuff industry and so on. The equipment is in conformity with the requirments of "GMP". Principle:
Let heat source (for example, low pressure steam or thermal oil) pass through the sealed jacket. The heat will be transmitted to raw material to be dried through inner shell;
Under driving of power, the tank is rotated slowly and the raw material inside it is mixed continuously. The purpose of reinforced drying can be realized;
The raw material is under vacuum. The drop of steam pressure makes the moisture (solvent) at the surface of raw material become saturation and will evaporate. The solvent will be discharged through vacuum pump and recovered in time. The inner moisture (solvent) of raw material will infiltrate, evaporate and discharge continuously. The three processes are carried out unceasingly and the purpose of drying can be realized within a short time. Applications :
It is suitable for the raw materials that need to concentrate, mixed and dried at low temperature (for example, biochemistry) products in chemical, pharmaceutical(like API) and foodstuff industries. Particularly it is suitable for the raw materials that are easy to be oxidized, volatilized and have night heat sensitivity and is toxic and not permitted to destroy its crystal in drying process.
Speed adjusting motor of 0-6rpm might be chosen according to the user's requirements.
The following aspects should be point out when to order:
1. The above-mentioned technical specs(model) are calculated based on material density of 0.6g/cm3. If it's over, please point out.
2. If certificate for pressure vessel is required, please point out.
3. If glass lining for interior surface is required, please point out.
If the material is explosive, or flammable, the calculation should be made according to trial result. Features :
When oil is used to heat, use automatic constant temperature control. It can be used for drying biology products and mine.
Its temperature of operation can be adjusted form 20-160 º C.
Compared to ordinary vacuum drying oven, its heat efficiency will be 2 times higher.
The heat is indirect. So the raw material can not be polluted. It is in conformity with the requirement of GMP. It is easy in washing and maintenance. Technical data:
