PRODUCT
DESCRIPTION
The Industrial Pre-Washer by Chenxing Recycling Machinery delivers heavy-duty contaminant removal for raffia, agricultural films, and PET/HDPE containers – handling 50% higher debris loads than standard systems. Featuring a high-torque auger with anti-jam rails, this preliminary washing equipment scrubs away 90%+ soils, sands, and metal fragments before downstream processing. Its auto-reverse system prevents motor overloads, while stainless steel screens discharge abrasive particles through 360° water jets, reducing equipment wear by 40%. Designed for highly contaminated plastics, the CE-certified pre-washer integrates with friction washers and sink-float tanks, achieving <2% residual impurities in recycled flakes. Backed by 20+ years of expertise, Chenxing’s modular design allows <15-minute screen swaps and FDA-grade material contact, ideal for post-consumer film recovery or rigid container purification. Customize with variable speed drives or automated sludge removal for 24/7 recycling lines – cutting water usage 25% vs conventional pre-washing systems.

FAQ
1. What is the purpose of a pre-washing machine in a bottle recycling line?
The pre-washing machine is designed to remove surface contaminants such as labels, dirt, sand, and oil from PET or HDPE bottles before the main hot washing stage. This improves the overall efficiency and cleanliness of the entire recycling process.
2. What types of bottles and containers is this machine suitable for?
It is commonly used for:
-
Post-consumer PET bottles (water, soda, juice)
-
HDPE bottles (milk, detergent, shampoo)
-
PP bottles and containers
It can process both whole bottles and pre-shredded fragments, depending on the configuration.
3. How does the pre-washing machine work?
Bottles are fed into a rotating drum or paddle washer where they are scrubbed with cold or warm water, often mixed with detergents. Internal paddles or blades agitate the materials to dislodge impurities, and spray bars help flush them away.
4. What are the benefits of using a pre-washing machine?
-
Improves final flake quality by reducing dirt and organic residues early
-
Protects downstream equipment from abrasion and clogging
-
Reduces chemical usage in the main hot washing stage
-
Improves de-labeling for shrink sleeve or glued labels
5. What is the typical capacity of a pre-washing unit?
Capacity varies from 500 kg/h to over 3000 kg/h, depending on the model and bottle size. Custom configurations are available for high-volume processing plants.
