Industrial Rotating Double Cone Vacuum Dryer Drying Machine
It is suitable for the raw materials that need to concentrate, mix
and dry at low temperature(eg. biochemistry products in chemical,
pharmaceutical and foodstuff indusries).
1. materials that are easy to oxidize
2. materials that are easy to volatilize
3. materials that having strong heat sensitive or toxic
4. materials that should not destroy its crystal in drying
1. heat source pass through the sealed jacket
2. the heat will be transmitted to the raw material to be dried
through inner shell
3. under driving of power, the tank is rotated slowly and the raw
material inside it is mixed continuously. then the purpose of
reinforced drying can realized
4. the material is at a vacuum state, the drop of steam jpressure
makes the moisture at the surface of raw material become saturation
and will evaporate
5. the solvent will be discharged through vacuum pump
6. the inner moisture of raw material will infiltrate, evaporate
and discharge continuously. these three processes are carried
continuously and the purpose of drying can be realized within a
SZG Series Conical Vacuum Dryer is a new generation drying device
developed byour factory on the basis of combining the technology of
similar equipment. It hastwo connecting ways, i.e. belt or chain.
Therefore it is stable in operation. Thespecial design guarantees
two shafts realize good concentricity. Heat medium andvacuum system
all adapt reliable rotating connector with the technology fromUSA.
On this basis, we also developed SZG-A. It can carry out steppless
speedchange and constant temperature control.
As a professional factory in drying industry, we supply hundred
sets to thecustomers every year. As for heat medium, it may be
thermal oil or steam or hotwater. For drying the adhesive raw
material, we have designed specially a stirringplate buffer for
● Heat source (for example, low pressure steam or thermal conduct
oil) passthrough the sealed jacket. The heat will be transmitted to
raw material to bedried through inner shell;
● Under driving of power, the tank is rotated slowly and the raw
material inside itis mixed continuously. The purpose of reinforced
drying can be realized;
● The raw material exists is under vacuum. The drop of steam
pressure makesthe moisture (solvent) at the surface of raw material
become saturation and willevaporate. The solvent will be discharged
through vacuum pump an recoveredin time. The inner moisture
(solvent) of raw material will infiltrate, evaporate anddischarge
continuously. The three processes are carried out unceasingly
andthe purpose of drying can be realized within a short time.
1. When oil is used to heat, use automatic constant temperature
control. It can beused for drying biology products and mine. Its
temperature of operation can beadjusted form 20-160 "C .
2. Compared to ordinal dryer, its heat efficiency will be 2 times
higher,The heat is indirect. So the raw material can not be
polluted. It is in conformitywith the requirement of GMP.
3. It is easy in washing and maintenance.
