1, unique sealing structure
Principle: a liquid inlet pipe through the liquid (gas ) tube flange and cylinder flange connection, the outer end of the packing seal, the leakage possibility minimum.
Advantage.:
To put an end to the inner leakage.
Adopting the outer sealing form, easy to find.
repair convenience : the traditional methods of leakage in cylinder must be found after hanging from the frame, tearing down the barrel shaft, replace the seals, is very difficult, and I plant the use of form, only to press the packing, in a very short period of time to complete, will not affect the normal production.
2, vacuum suction type for improvement
General double cone in the long-term use, suction head is constantly cylinder body turned up material flapping, resulting in vacuum tube bending deformation, deformation after the vacuum tube can not be very good sealing, causing the vacuum drops, even suction head and the vacuum tube welding fracture, in order to reduce the filtration area, reduce the suction head height, I plant will be rounded into a prismatic, to reduce the material and the filter head tapping area can be improved, avoiding the above problems.
3, with quick connectors
Inlet valve and a quick joint, feeding only on the hose, can carry out vacuum pumping material, fast and convenient, can greatly reduce labor intensity.

| Material by vacuum suction cylinder, initial moisture of material drying process, higher, the hot air is introduced into the drying chamber by a special wind distribution plate distribution, material in the hot air and the cylinder rotates continuously under the action of state formation of fountain. Hot air and the jacket heat source and material of sufficient heat exchange, so that water discharged by rapid evaporation, vacuum system. As the body rotates, wet material in contact with the tank wall surface is constantly updated, so that uniform for drying process.

|
- In the drying process, the cylinder rotates, so that material constantly flipping, uniform drying.
- In the vacuum state, with hot air and sleeve heat dual drying, thereby greatly shorten the drying time.
- Heating methods such as using water heating, automatic temperature control device, the heat-sensitive materials drying.
- On the corrosive chemical material, the inner wall of the cylinder can adopt glass lining.
- Adding airflow drying, and high drying efficiency, compared with the traditional double conical vacuum dryer to improve 3-5 times.
- At the same time with the airflow dryer, efficient boiling dryer, double cone vacuum dryer has the advantages. This machine is simple in operation, continuous operation, also can be fixed point operation.
