Principle of impregnation dryer

Working principle: the hot air enters the mixing and crushing drying chamber from the bottom of the dryer through the inlet pipe at a suitable spouting speed, which produces strong shearing, blowing and rotating effects on the materials. Therefore, the materials are subjected to centrifugation, shearing, collision and friction, and are granulated, which enhances the mass transfer and heat transfer. At the bottom of the dryer, the larger and wetter particles are mechanically broken under the action of the stirrer. The particles with lower moisture content and smaller particle size are entrained and lifted by the rotating air flow and further dried during the lifting process. As the gas-solid two-phase flows in rotation, the inertia of the solid phase is greater than that of the gas phase, and the relative velocity between the solid and gas phases is larger, which enhances the mass transfer and heat transfer between the two phases. Therefore, the production intensity of this machine is high. characteristic:

● due to the high dispersion of the materials due to centrifugation, shearing, collision and friction, the relative speed of the solid and gas phases is large, which enhances the mass and heat transfer and makes the production intensity of the machine high.

● when the drying gas enters the bottom of the dryer, it will generate a strong rotating air flow, which will have a strong scouring effect on the materials on the wall of the dryer and eliminate the wall sticking phenomenon.

● in the high temperature area at the bottom of the dryer, the heat sensitive materials do not directly contact with the hot surface, and special devices are installed to solve the problem of coking and discoloration of the heat sensitive materials

● due to the high circumferential gas velocity in the drying room and the short residence time of materials, the rapid, small equipment and large-scale production can be achieved.

● adding ceramic ring and swirl plate on the upper part of the drying chamber can control the particle size and humidity of the outlet materials to meet the requirements of the final moisture particle size of different materials.
