The joys and sorrows of tattered

The entire production line should achieve automated closed processes, continuous flow operations, information-based measurement and control systems, clean production methods, and harmless treatment processes.

China Investment: What are the main technical difficulties in the production process of food grade polyester chips? Why did Yingchuang become a crab eater?

Yao Yaxiong: The first step of the entire process is very important, which is to separate the cap and label of the waste bottle as much as possible in the front-end processing flow. Although they are impurities in the production of high-purity polyester chips, the PE material used for bottle caps and the PP and OPS materials used for labels can also be recycled and reused.

In the following processes such as melt extrusion, vacuum pumping, filtration, underwater granulation, crystallization drying, and solid-state polymerization, the high-purity polyester fragments are immediately upgraded and transformed into high-quality bottle grade polyester chips. The technical equipment in this processing flow, such as the 12 screw ring extruder, cannot be manufactured domestically yet.

Later on, it is also crucial to achieve automated closed processes, continuous flow operations, information-based measurement and control systems, clean production methods, and harmless treatment processes for the entire operation line.

I believe the key to our company becoming a leading domestic enterprise in this field is not only the integration of world-class equipment, but more importantly, the adoption of a standardized and controllable management model. After selecting the right direction, the company has obtained certification from the US FDA and multinational corporations such as Coca Cola, opening the door for its products to be sold in the international market. This is of great significance for the company's development and product sales.
