Double cone rotary vacuum dryer is a new type of drier, mixing and drying in one.
The working principle of double cone rotary vacuum dryer is: will the condenser, vacuum pump and vacuum drying dryer supporting device. (if not need solvent recovery, the condenser can not) this machine has advanced design, simple structure, easy cleaning, the material can be fully discharged, simple operation. Can reduce the labor intensity, DCS control system, distributed control system, the control system of Dcs distributed control system, automatic control system, improve the working environment. At the same time because the container itself rotates material also rotates, but the wall of the material is not deposited, so the heat transfer coefficient is high, the drying rate are high, not only to save energy, and even drying of the material fully, good quality. Can be widely used in pharmaceutical, chemical, food, dyestuff industry drying. Double cone rotary vacuum dryer can be effectively used in production, it is a system concept, the organic solvent recovery system is a key process. The manufacturer in the supply of double cone rotary vacuum dryer equipment, not only provide a single, but should provide system, should consider the recovery of organic solvent, the solvent with low boiling point, the frozen water cooling, to ensure that the solvent can be recycled, avoid the vacuum pump air pollution left.
Due to the double cone rotary vacuum dryer was improved will help improve the work efficiency of the equipments.
Double cone rotary vacuum dryer stirring and crushing function. Some domestic manufacturers to adopt the crushing device, the device for tool four integral structure, the use of the cross arrangement, from short to long, followed by welding, cutting tools with different length, different angles. Ensure that rotates in full contact with the material, to ensure the crushing effect. This material in the double cone rotary cylinder kept flipping, and heat exchange with the wall (wall outside half section coil with hot water circulation heating). At the same time to rotate in the double cone cylinder rotating crushing knife, when the cylinder rotates a circle, the material and the crushing cutter contact time. The crushing knife fast speed (up to 250rpm), and the cylinder speed slower (usually 3rpm), so when the material and tool contact, crushing effect is very obvious, the cylinder body operating under vacuum system.
Double cone rotary vacuum dryer mixing and granulating function. In the vacuum tube is penetrated in the pumping with a nozzle tube double cone rotary vacuum dryer (spray adhesive), at the same time the tube into the inner part of the barrel body is additionally provided with a fixed blade. When the rotation of the cylinder process, fixed in the vacuum tube mixing blade forces the material from its two side flow, so in the material cylinder wall along the sliding at the same time, and increases the radial motion. Therefore, effectively improves the effect of mixing and stirring up the material, moisture evaporation, improve drying rate. Then at the end of powder material process, can be penetrated with nozzle (spraying adhesive spray pipe) corresponding adhesive powder, dry material made of granular products. |
