In large-scale agricultural film recycling, achieving a consistent output of 5000kg/h requires more than just larger machinery; it demands a strategic rethink of material flow. Drip irrigation tapes are notoriously difficult to process due to high levels of sand, soil, and residual water.

When operating at such high volumes, a standard linear configuration often creates “bottlenecks”—points where the volume of material exceeds the processing capacity of a single machine. The solution lies in a high-capacity Drip tape washing line designed with a parallel processing architecture.

Addressing Bottlenecks in the 5000 kg/h PE film washing line

The primary challenge in a 5000 kg/h PE film washing line is managing the sheer mass of wet, soft material. In the initial cleaning stages, powerful friction is required to dislodge embedded soil. Our system utilizes a diagonal friction washer and a high-power parallel friction washer to perform aggressive pre-washing. However, once the material enters the rinsing stage, the risk of accumulation increases.

To prevent this, the material is fed into a 10-meter scraper rinsing tank. The innovation here is at the discharge point: rather than a single outlet, the tank feeds into two parallel vertical lifters (dewatering machines). By splitting the 5-ton-per-hour stream into two manageable 2.5-ton flows, the system ensures that the material is moved efficiently into the next stage without clogging or overflowing.

The Rationale for a Parallel Processing Recycling Line

The strategy of a parallel processing recycling line continues through the secondary rinsing stage. The material is conveyed into two separate, 9-meter clean water tanks. Each of these tanks is equipped with two additional vertical lifters, bringing the total to four lifting units at this stage.

This redundancy is calculated engineering. Soft materials like drip tape tend to clump when wet, significantly increasing the load on lifting and conveying equipment. By distributing this load across multiple units, we maintain a consistent flow rate. This configuration is essential for any facility aiming for high-purity output while maintaining the rigorous speed of a high-capacity scrap drip tape washing recycling line.

Maximizing Throughput with a Washing Line with Double Dryerystem

The final and most critical bottleneck in any film recycling plant is the drying stage. Soft PE film retains a high percentage of moisture, and attempting to dry 5000kg/h with a single unit is mechanically unfeasible. Therefore, our design concludes with a washing line with double dryer system.

The output from the final rinsing tanks is directed into two heavy-duty horizontal dewatering machines. These industrial-grade dryers utilize high-speed centrifugal force to strip moisture from the flakes. Splitting the final output between two dryers ensures that the material achieves the low moisture content required for high-quality pelletizing. Finally, the dried flakes are conveyed via stainless steel air-conveying pipelines into a silo, ready for the plastic pellet extruder.

A System Designed for Scale

Investing in a drip tape washing line of this magnitude is a decision based on long-term operational stability. By employing parallel processing at critical junctures—specifically at the lifting and drying stages—we ensure that the plant operates at peak capacity with minimal risk of downtime. This systematic approach transforms heavily contaminated agricultural waste into a clean, valuable commodity at an industrial scale.
