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. 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. Increasing the stirring and granulating function.
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.
In the cleaning part of double cone rotary vacuum dryer cylinder, some by switching the vacuum line into the water, cleaning the rotating cylinder and then put the net, so dynamic and cleaning method is not thoroughly cleaned, at least in the dynamic contact surface and the bonding material is not washed. The second is some manufacturers not to cylinder as pressure vessel design and manufacture, is very difficult to switch the vacuum line steam sterilization, sterilization in place so no steam. This course involves feeding / discharging structure and sealing structure, its form and the bearing performance is also associated with steam sterilization. In the sterile environment using equipment essential requirement is cleaning after sterilization, the most effective method and direct method of sterilization is usually in moist and dry heat sterilization, based on the cylinder structure is not detachable, cannot use the dry heat sterilization, can only use the damp heat (steam) sterilization. Double cone rotary vacuum dryer can quickly open external spray cleaning device, when stopping access tube, and the formation of cleaning loop system. Cylinder fitness could be the whole double cone rotary vacuum dryer disassembly (such as clamping type conical mixer structure, so that the entire cylinder into) physical cleaning station complete cleaning and sterilization, of course, this assumption is too hard. And this is also the basis of double cone rotary vacuum dryer can upgrade, so that it can adapt to the aseptic production. |
