Operating Principle of Particles in PVC Mixer


The PVC mixer is a large batch of drying equipment that uses the principle of instantaneous drying. It utilizes the rapid movement of hot air to drive wet materials and suspend them in hot air. This strengthens the entire drying process and improves the rate of heat and mass transfer. After airflow drying, the unbound moisture can almost be removed, and the dried materials will not deteriorate, The output can be significantly improved compared to ordinary dryer drying, and users can achieve high economic benefits in a short period of time.

During the movement of the PVC mixer, particles continue to decelerate due to resistance until the deceleration ends. The drying tube suddenly shrinks again, so that the particles are accelerated again. By alternately reducing and expanding the diameter of the tube, the movement speed of the particles is also alternately accelerated and decelerated. The relative velocity and heat transfer area between the air and the particles are larger, thereby enhancing the heat and mass transfer rate. At the same time, the decrease in the air flow velocity in the expanded tube also correspondingly increases the drying time.
