| Conical Bottom Helical Ribbon Mixer Vacuum Dryer is a kind of multi-functional mixing and drying machine, it is a batch type fully closed process equipment for solid mixture and vacuum drying, which is widely used in chemical industry, fine chemical industry, food industry and pharmaceutical process industry. The corrosion resistance and cleanness of the cylinder metal material (Stainess steel) is especially suitable for medium in the above industries. Conical Bottom Helical Ribbon Mixer Vacuum Dryer is a vertical type pressure vessel equipment. Its constructure mainly includes a cylindrical upper vessel with a head or only a flanged head, a flange mounted type detachable movable conical bottom vessel with discharge valve, heating/cooling jacket, agitating/stirring device, motorgear device, dust filter, temperature and pressure measurement device and etc.,also canbe assembly with hollow shaft heating system, online weighting device, online washing device(CIP/MIP), online sampling valve, SIP system, vacuum system, external hot water/thermal oil circulating system, PLC control system. |

| Suitable materials in powder,granular or fiber state: | Low viscosity, small particle size (particle size<2mm) materials; High viscosity, paste and slurry state material can also be dried with this equipment, and the feeding particle size of fragile materials can be appropriately enlarged after drying, but it is necessary to conduct tests to verify the appropriate materials, cone angle design and the capacity of driving motor; Heat-sensitive materials that should be drying at low temperature; Oxygen-sensitive with hazardous materials; Materials that requiring recovery of toxic solvents and gases; Materials that required with low residual volatile content; Materials that required mixed/blended sufficiently and evenly. |
| Inapplication materials and operating conditions: | In order to ensure the service life of the equipment, can not be application with following material & operating conditions: Stainless steel corrodes rapidly in the presence of chloride ions, even more than ordinary mild steel. Therefore, there are requirements for the use environment of stainless steel, and it needs to be wiped frequently to remove dust and keep it clean and dry. Inhabit operating over designed pressure and temperature. Materials that easy to agglomerate during drying process |
Helical ribbon type agitator is a kind of with low shear force that lifted and dropped freely along the inner wall of the cone dived by motor&reducer, the material continuously sheared and dispersed to ensure all materials in the cone can be fully moved, for the materials are not squeezed by any other external force, so avoiding the ineffective friction between materials and equipment as well as between material particles, and eliminating the possibility of material caking during the drying process, which greatly improves the mixing and drying efficiency of materials.

| Conical Bottom Helical Ribbon Mixer Vacuum Dryer is special designed for solid mixing & drying: 1/ The variable frequency motor via reducer drive the helical ribbon agitator rotating to achieve the material lifting along the inner wall of conical vessel from bottom to top; 2/ and then falling down by weight from top to bottom; 3/ During upper process the material are forced to vertical and axial motion in the vessel continuously and contact the inner wall for heating, the heat is mutually diffused in the materials by relatively convective and mixed, and achieving the effect of heating and drying in a short time; 4/ The water/solvent inside the material is constantly evaporated and the vapor is led out by the vacuum pump. If the vapor/liquid needs to be recovered, the system can be adding a condenser and recovery the liquid to a storage tank, this condenser can be installed before or after the vacuum pump, depending on the properties of the solvents;5/ The dryed material discharge by the bottom valve. |
