Scope of application

OCR series closed cycle drying crystallizer is used to continuously crystallize amorphous materials, crystallize PET raw materials or recycled materials that have not yet crystallized into crystalline raw materials that can be directly dehumidified and dried. The system includes heating device, thermal insulation material barrel and mixing components. When the amorphous PET raw materials or crushed materials enter the hopper, they are crystallized and stirred at the same time, which can prevent the raw materials from caking and reduce the defective rate of products. The crystallized plastic can be transported from the bottom of the hopper to the storage bucket or directly to the drying bucket for drying.

working principle

After starting suction, the electric hot air blower starts and the raw materials begin to heat. When the raw materials are stacked to the position higher than the material level switch, the main control box stops outputting signals to the suction machine. The raw material is heated for a period of time. When the temperature sensing probe of the barrel reaches the set crystallization temperature, the raw material is sent out by the feeding device; At this time, as the material level in the hopper gradually decreases, the suction device starts to supplement the uncrystallized raw materials to realize the continuous crystallization operation.

Product features

1. Simplify and improve the drying efficiency of raw materials;

2. The constant speed stirring design makes the uncrystallized plastic not stick and form blocks in the crystallization process temperature;

3. It can dry raw materials at high temperature, which greatly improves the work efficiency;

4. The standard cyclone dust collector is used in places with more dust, which can effectively reduce the load of the filter bag, prolong the service life of the filter bag and reduce the cleaning times of the filter bag;

5. There is a double filter protection device, which can reduce accidents caused by human or mechanical faults;

6. Equipped with rotary blanking valve with good sealing performance to ensure accurate and stable output of crystalline raw materials;

7. Equipped with material level switch, accurate material level detection and safe and reliable machine operation;

8. The negative pressure detector is equipped to detect the ventilation of the filter immediately. When the load exceeds the set value, the alarm shall be given in time to prompt cleaning, so as to avoid filter blockage.

characteristic

→ PET resin raw materials are most widely used in high polymer products such as textile fiber, food, pharmaceutical packaging raw materials, tape film, industrial silk, high temperature resistant tableware and so on. The melting and blistering defects will occur at high temperature.

→ due to the need for special drying treatment and the rapid development in the packaging field, aoshide machinery provides a reliable dehumidification and drying technical guarantee for the majority of pet injection molding equipment and product manufacturers. It is widely used in the crystallization, drying and complete set of dehumidification, drying and crystallization process equipment of PET raw materials.

→ aoshide machinery's advanced technology in the field of pet molding system auxiliary equipment is suitable for the needs of various application fields: bottle making, embryo making, thermoforming film and sheet production, packaging belt, industrial silk production, pipe production, waste recycling production and other similar fields.
