Application Areas:

PET bottle washing lines convert used bottles — mineral water, soft drinks, cooking oil, and preforms — into clean, contaminant-free flakes ready for reuse. The standard output is “hot washed” PET flake suitable for polyester staple fiber production or direct pelletizing into granules for new bottle manufacturing.

System Overview

System Overview
The plant processes dirty baled bottles into clean flakes with high commercial value. Capacity ranges from 300 kg/h to 3,000 kg/h depending on configuration. The line also recovers clean PP/PE caps, labels, and paper clips as separate revenue streams.

Process Steps: Bale unpacking → Pre-washing → Sorting → Metal detection → Crushing → Floating wash → Hot wash → Friction scrub → Rinse → Dewatering → Drying → Packaging

Technical Features:

High automation — PLC-controlled with touchscreen HMI, reducing labor costs especially for three-shift operations. Capacity: 300–3,000 kg/h

Modular control — Integrated central control with independent machine-level PLCs for easy monitoring, troubleshooting, and emergency stop

304 stainless steel — All material and water contact surfaces use food-grade stainless steel, preventing secondary contamination

Integrated drying — Flakes exit completely dry and ready for direct packaging or pelletizing

Customizable configuration — Line layout adjusts to input contamination level and target flake quality specifications

Downstream ready — Optional pelletizing module converts washed flake directly into PET granules for bottle-to-bottle recycling
