Description
Technical Field
The utility model belongs to the technical field of drying equipment, and particularly relates to a spiral vacuum drying and sterilizing system.
Background
The existing spiral dryer adopts a shaft screw, and the existing spiral dryer adopts a structure that a hollow screw shaft is combined with a hollow spiral sheet (such as Chinese patent documents CN208254181U and CN 208425491U). The existing spiral dryer only has a section of heating and drying process, and a cavity is not vacuumized. Therefore, when viscous and easily-wound materials are conveyed, the whole spiral shaft is easily wrapped by the materials, so that the conveying function of the spiral shaft is lost, and the equipment cannot normally work; and after the primary drying, the function of crushing the large materials is not realized, the drying process of the large materials consumes longer time, and the drying efficiency is low. In addition, the existing vacuum spiral conveyor (CN207317431U) is a vertical conical spiral and also has a shaft structure, and is not suitable for treating easily-wound viscous materials.
For this reason, the following two methods are generally used for a highly viscous and easily entangled material. 1. The material to be dried is fed into the cylinder by a conveying device (generally a screw conveyor) through a feed inlet. The shaft with the stirring rake teeth rotates continuously to stir the materials, and the materials do reciprocating motion. The heating is generally designed into a jacket or a semi-tube type by a rake type vacuum dryer, a heat source such as steam/heat conducting oil/hot water is introduced into the rake type vacuum dryer, and simultaneously, the shaft and the rake wall are also designed into a hollow shape, so that heat is transferred to the materials in two aspects. Meanwhile, the inside of the cylinder is vacuumized through the vacuum port, and the evaporated moisture is also pumped out of the dryer while the vacuum degree in the cylinder is maintained. If a condenser is added, the solvent can be recovered. The most important is intermittent operation, continuous conveying can not be realized, materials are not easy to discharge, and dry varieties are not easy to replace. 2. The double-cone vacuum dryer is also an intermittent dryer, and has low efficiency. There is therefore a need for improvement.
