Overview

ZDG seriesVacuum ribbon dryerThis is a new generation of vacuum drying and mixing equipment developed by our factory to digest and absorb similar foreign products. The equipment integrates drying, crushing, vacuum pressure reduction, and powder mixing. It consists of a motor, reducer, frame, mechanical seal, filter, spiral stirrer, conical cylinder with jacket heating, and discharge valve. It can achieve continuous operation of the entire process in a closed manner. Its drying efficiency is 3-5 times that of the SZG series double cone rotary vacuum dryer of the same specifications. It is mainly used for powder drying in industries such as pharmaceuticals, chemicals, pesticides, and food, and can achieve continuous operation of the entire process in a closed manner. It is the preferred drying equipment for the above industries.

working principle

The main body of the ZDG series vacuum ribbon dryer is vertically stationary, and the internally heated ribbon undergoes circular stirring and lifting motion. The ribbon agitator is driven by a motor reducer to rotate, and the animal material is carried along the conical cylinder and lifted from bottom to top. After reaching the highest point, the material flows automatically to the center of the vortex and returns to the bottom of the conical cylinder under the action of gravity and inertia. The entire process forces the material to be heated in the conical cylinder, with relative convection and mixing. The heat diffuses in the material, causing the material to undergo irregular reciprocating motion in all directions, completing high-frequency heat transfer and exchange between the material and the cylinder wall surface. The solvent evaporated by heating is extracted in a vacuum state, achieving the effect of heating and drying in a short time.

Features of the equipment
