Principle of plastic granule crystallization dryer,Principle of Crystal Dryer：The PET pre-crystallization dryer mainly relies on the vibration exciter from the bottom of the container to generate mechanical excitation force, so that the container generates periodic vibration force. Because the inner bottom of the PET pre-crystallization dryer container is a cylindrical shape, the amplitude of each point is different, so that the material in the PET pre-crystallization dryer container revolves around the center axis of the container, and then rolls around the center of the PET pre-crystallization dryer cylinder, forming a ring Spiral movement to achieve a dry state. The dried material is in contact with the inner wall of the jacket-heated container and transfers heat to increase the temperature. After reaching the vaporization point, the moisture is vaporized and discharged under vacuum, so that the material can be dehydrated and dried quickly.
Advantages of PET pre-crystallization dryer:
1. Large material handling capacity, low fuel consumption and low drying cost.
2. It has the characteristics of high temperature resistance and can use high temperature hot air to quickly dry the material.
3. Strong anti-overload ability, stable running of the cylinder and high reliability.
4. With the self-aligning tug structure, the tug and the rolling ring are well matched, which greatly reduces wear and power consumption.
5. Strong expandability, the design takes into account the production margin, even if the output increases slightly, there is no need to replace the equipment. |
