The Crate Washing Machine is an industrial-grade cleaning system designed for food processing facilities requiring efficient, hygienic cleaning of turnover containers. Built entirely from SUS304 food-grade stainless steel, it integrates multi-stage washing, high-temperature sterilization, and optional air drying into a single continuous automated process.
Two models are available to match different throughput requirements:
· HE-3600 — 3-stage cleaning (Pre-wash → Main-wash → Washing), processing 300–600 crates per hour
· HE-4800 — 4-stage cleaning (Pre-wash → Main-wash → Rinsing → Washing), processing 600–1,000 crates per hour
Both models handle plastic baskets, crates, trays, boxes, pallets, and egg trays — suitable for meat, poultry, seafood, vegetable, and prepared food processing operations.

↓
Stage 1: Pre-wash
High-flow water softens and loosens surface residue
↓
Stage 2: Main-wash
High-pressure spray detaches stubborn stains and organic buildup
↓
Stage 3: Rinsing (HE-4800 only)
Circulating clean water flushes remaining detergent residue
↓
Stage 4: Clean Water Wash
Fresh water performs final thorough rinse — zero residue
↓
(Optional) Air Drying
Scroll blowers remove residual water droplets for immediate reuse

Clean, sanitized crates exit the machine
Application | Suitable For |
Meat & Poultry Processing Crates | Slaughterhouse turnover crates — remove blood, fat, organic residue |
Seafood Containers | Processing tubs and crates — remove scales, slime, salt deposits |
Vegetable & Fruit Baskets | Harvest crates — remove soil, debris, pesticide residue |
Egg Trays | Remove egg residue; sanitize tray surfaces for reuse |
Food Delivery Boxes | Distribution containers for food safety compliance |
Pallets & Waste Bins | Large-container and sanitary bin cleaning |
What is the difference between HE-3600 and HE-4800?
The HE-3600 uses a 3-stage process with 2 water tanks, suitable for medium-volume operations at 300–600 crates/h. The HE-4800 adds a dedicated rinsing stage (4 stages, 3 tanks) for higher throughput (600–1,000 crates/h) and improved cleanliness. Model selection depends on daily crate volume and cleanliness requirements.
What types of containers can the machine clean?
Plastic baskets, crates, trays, boxes, pallets, waste bins, and egg trays. Adjustable side rails accommodate different container widths up to 650 mm.
Should I choose PLC control or button control?
The PLC touchscreen is recommended for larger facilities needing programmable cycles, automated monitoring, and data logging. The button control panel is cost-effective for smaller operations with straightforward requirements. Both display real-time water temperature and status.
Is the air drying function standard?
No — it is an optional add-on. Recommended when crates need to be reused immediately after washing without manual drying.
How is water temperature controlled?
Float devices and temperature probes connected to solenoid valves automatically mix cold and hot water (steam heated) to maintain set temperatures (82°C or 95°C), minimizing energy consumption while ensuring consistent sterilization.
Can the machine be customized?
Yes. Dimensions, cleaning stages, pump configurations, water tank capacity, drying section length, electrical voltage, and control system can all be customized. Share your facility layout and throughput requirements for a tailored recommendation.
