Continuous Hot Washer System
Achieve food-grade purity for PET and HDPE flakes with our advanced hot chemical washing and high-friction cleaning technology.
The Key to Premium Recycled Flakes
Our system is engineered to deliver superior cleaning performance, ensuring your final product meets the highest quality standards.
Superior Decontamination
Hot chemical washing effectively dissolves stubborn glue, oil, and organic residues that cold washing leaves behind.
High-Efficiency Throughput
The continuous flow design eliminates downtime between batches, ensuring a consistent, high-capacity output for your entire line.
Robust Stainless Steel Build
Constructed entirely from SUS304 stainless steel for maximum durability, corrosion resistance, and to prevent material contamination.
Intense Friction Scrubbing
High-speed rotary paddles create intense friction between flakes, scrubbing surfaces clean in a single, efficient cycle.
From Contaminated Flakes to Food-Grade Purity
Standard washing processes fail to remove the toughest contaminants, limiting the value and application of your recycled flakes. Our hot washer is the solution.
Problem: Stubborn Contaminants
Residual label glue, oil, grease, and beverage residues remain on flakes after cold washing, leading to lower-grade, discolored, and odorous rPET.
Solution: Total Impurity Removal
The combination of hot water, chemical agents, and intense friction dissolves and scrubs away all contaminants, producing exceptionally clean, pure flakes.
Problem: Inefficient Batch Washing
Traditional batch washers create bottlenecks in a continuous recycling line, requiring downtime for loading and unloading, which lowers overall plant output.
The 4-Stage Continuous Cleaning Cycle
A systematic, automated process that ensures every flake is thoroughly decontaminated for the highest quality results.
1. Hot Chemical Soak
Flakes enter a heated bath with a cleaning solution, which begins to break down and dissolve glues and oily residues.
2. High-Friction Scrubbing
High-speed rotary paddles vigorously agitate the flakes, forcing them to rub against each other and scrub all surfaces clean.
3. Continuous Material Flow
The system is designed for a constant, uninterrupted flow of material, ensuring consistent cleaning and maximum throughput.
4. Purified Flake Discharge
After the deep clean cycle, the exceptionally clean flakes are automatically discharged for the next stage of the washing line.

Frequently Asked Questions
Why is hot washing necessary for PET flakes?
Cold washing can remove dirt and debris, but it is ineffective against stubborn contaminants like the glue from labels and residual oils or fats from the bottle’s original contents. Hot water (typically 80-90°C), combined with a chemical agent, is essential to dissolve these substances and produce the high-purity flakes required for premium applications.
What does “continuous” operation mean for my plant?
A continuous system means there is no downtime between loads. Material is constantly fed in, processed, and discharged, integrating seamlessly into your washing line. This is much more efficient than a “batch” washer, which must be stopped, emptied, and refilled, creating bottlenecks and lowering the overall throughput of your facility.
What kind of maintenance is required?
The system is designed for robust, long-term operation. Routine maintenance includes checking the motor and bearings for proper lubrication and inspecting the rotary paddles and interior surfaces for wear over time. The SUS304 stainless steel construction minimizes corrosion and simplifies cleaning.
