Crystallization dryer detailed introduction |
What is a Crystallization dryer
Crystal dryer (also known as stirring dryer, pre-crystal dryer, pre-crystal dryer); the crystal dryer has a large processing capacity, low energy consumption, and low drying cost. The PET crystal dryer has the characteristics of high temperature resistance, and can use high temperature hot air to quickly dry the material. The PET crystal dryer has strong expandability, and the design takes into account the production margin. Even if the output increases slightly, there is no need to replace the equipment. The PET crystal dryer adopts a self-aligning tug structure, and the tug and the rolling ring are well matched, which greatly reduces wear and power consumption. The blocking wheel structure specially designed for the stainless steel PET crystal dryer greatly reduces the horizontal thrust caused by the inclined work of the equipment. The PET crystal dryer has strong anti-overload ability, stable operation of the cylinder and high reliability. The PET crystal dryer mainly relies on low cost, so that the container generates periodic vibration. Because the bottom of the container of the PET crystal dryer has a low cost and the amplitude of each point is different, the material in the container of the PET crystal dryer revolves around the central axis of the container, and then rolls around the center of the cylinder of the PET crystal dryer, forming a circular spiral motion. So as to achieve a dry state. The dried material is in contact with the inner wall of the jacket-heated container to transfer heat and heat up. After reaching the vaporization point, the moisture is vaporized and drained out under vacuum, so that the material is quickly dehydrated and dried.

In the processing of many engineering plastics such as PET, PLA, etc., in addition to dehumidification and drying, it also shows that it can be crystallized. Ordinary dehumidification dryers can only dehumidify and dry, while crystal dryers can help crystallize in addition to drying and drying. Powerful, mainly used in plastics, chemical, optics and other industries with a wide range of applications. It is characterized by fast drying speed, low energy consumption, can maintain the physical properties of the raw materials, and high product molding quality.
Features of crystallization dryer:1. Simple operation The dryer adopts a man-machine interface control system for the control of double tower switching, heating unit feeding unit, etc., simple and easy-to-understand digital touch screen and accurate and convenient diagnosis software, simple operation and easy monitoring. 2. Fast drying efficiency and low energy consumption The material of the crystallization dryer is evenly heated, the heat exchange is sufficient, the thermal efficiency is high, the drying intensity is high, the energy consumption is low, and the energy saving is about 30% compared with the ordinary dryer. The dehumidification drying system has a single material flow direction, no back-mixing phenomenon, uniform drying, stable quality, and no mixing. 3. Easy to adjust and control, strong applicability The drying process can be optimized by adjusting the thickness of the material layer, the rotation speed of the main shaft, the number of harrow arms, and the size of the harrow blades. The residence time of the material can be precisely adjusted, and each layer of the drying plate can be individually fed with a heating or cooling medium to heat or cool the material, and the material temperature control is more accurate and easy. Stable fluidization, no dead ends and blow-through phenomenon, little damage to the surface of the material, can be used for fragile drying, and the work effect is not affected when the material particles are irregular. 4. Convenient installation and small floor space The dryer can be delivered as a whole, and transported as a whole. It only needs to be hoisted in place, and the installation and positioning are very easy. Due to the vertical arrangement and vertical installation of the drying trays, the space utilization rate can be increased, the floor space is small, and a large-scale drying area can be achieved. 5. Stable operation, energy saving and environmental protection The vibration source of the dryer is driven by a vibration motor, with balanced operation, convenient maintenance, low noise and long life. Due to the application of vibration, the minimum fluidization gas velocity can be reduced, which can significantly reduce the air demand, thereby reducing the dust layer entrainment. The supporting heat source, fan, cyclone, etc. can also be correspondingly reduced in size, the complete set of equipment is reduced, and the energy saving effect is obvious. And there is no dust pollution problem. Crystal dryer not only has fast drying efficiency and good crystal dehumidification effect, but also reduces energy loss, saves costs, and brings more benefits to the enterprise. It can be used in different industries such as plastics, food, pharmacy, biology, chemical industry, etc., and plays an important role.
Crystallization dryer applicationr
Application of crystal dryer: 1. It can be equipped with a dehumidifier to directly perform dehumidification operations; 2. Optional vacuum hopper, suction machine, magnetic base, suction box for conveying operations; 3. Optional screw feeder can transport uncrystallized raw material and PET flakes stably and uniformly.
Crystal dryer operation:①. Temperature measurement and control range: 0-180 degrees ②. Heating, PID temperature control method ③. 24-hour real time display ④. Nine segments timing on and off function ⑤. Power-on delay and power-off delay ⑥. Automatic power-on time setting: In the case of power-on, press the "SET" button to set the light on, and then press the "Timer" button again, then "ON1" will be displayed on the PV, and then press the "Timer" button again. “ON2” is displayed on the PV, and so on, it is displayed cyclically between “ON1~ON9”, and the corresponding automatic power-on time is displayed on “TIME” in a flashing manner. At this time, you can press the “plus” or “minus” button. "Key" and "Shift key" can modify the current set value. After finishing the setting, press the "Set" button to exit and save the parameters. ⑦. Automatic shutdown time setting: Under the power-on condition, press the "SET" button to set the light on, and then press the "Delay" button again, then "OF1" will be displayed on the PV, and then press the "Delay" button.
