A pharmaceutical manufacturing plant needed to clean large numbers of plastic turnover baskets (product crates) between batches. Because the baskets directly touch medicine materials and finished products, the facility operates under GMP cleanroom standards — baskets must be completely dry and free of water stains before they re-enter the production area.
Manual washing left residual moisture, which meant baskets had to sit on draining racks for hours before reuse. This slowed down batch changeovers and created a hygiene risk: damp baskets in a cleanroom environment can breed bacteria. The customer needed a machine that could wash and dry in one pass.
The LIWEISHI Solution
We installed the LIWEISHI Custom basket washer — a continuous tunnel-type system designed for plastic turnover crates and baskets used in food, pharmaceutical, and chemical industries.
How It Works
The basket enters on a conveyor and passes through three stages automatically:
- Pre-wash stage (40–50°C) — high-pressure spray removes surface residue and loose particles
- Main wash stage (55–65°C) — detergent spray with rotating arms deep-cleans all sides of the basket
- Final rinse + dry stage (85°C+ hot air) — sanitizing rinse followed immediately by a forced hot-air drying tunnel
Baskets come out fully washed, sanitized, and dry in a single cycle — no manual wiping, no draining rack, no waiting.
Why It Fits Pharmaceutical Use
- Inline drying solves the cleanroom problem — baskets re-enter production immediately, no moisture, no contamination risk
- All stainless steel interior — smooth surfaces, no crevices, easy to clean and disinfect
- High-temperature sanitizing rinse — meets GMP hygiene requirements for product-contact equipment
- Continuous throughput — handles the high volume of baskets generated by batch production lines
Result
After installation, the customer’s basket turnaround time dropped from hours of air-drying to under 5 minutes per batch. Wet baskets waiting on draining racks became a thing of the past, and the cleanroom hygiene audit passed without issues.
Suitable Applications
Pharmaceutical factories, food processing plants, chemical plants, and any facility using plastic turnover crates that require washing and drying in one automated pass.
