Industrial Crate Washer Machine
TINDO
Product Description
Product Introduction: The Tindotech Industrial Crate Washer Machine is a heavy-duty tunnel cleaning system purpose-built for the most demanding container types in food processing and logistics. Unlike tray washers designed for flat and shallow items, this machine is engineered specifically for deep-sided, high-walled containers — including meat lugs, fish crates, Euro pallet boxes, DOLAV bins, and industrial logistics totes.
Equipped with a 4-stage washing process, extended dwell time, and a high-volume pump system delivering consistent pressure to container corners and recesses, it achieves a throughput of 800–1,200 containers per hour. Constructed entirely from SUS304 stainless steel and fully CE certified, this machine meets the rigorous sanitation standards of HACCP-compliant facilities worldwide.
Our recent commissioning of a 6.5-meter XXL tunnel system for a Russian food processing giant — the third Tindotech washer delivered to Russia in 2026 — demonstrates our ability to engineer at any scale required. Read the full case study →
Looking for a tray or baking pan washer? Our Automatic Tray Washing Machine is specifically optimized for flat containers like baking pans, IQF pallets, and drying racks.
Standard tray washers struggle with tall containers — spray pressure dissipates before reaching the bottom corners, and short tunnels don't provide enough dwell time for thorough cleaning. The Tindotech Industrial Crate Washer solves both problems.
Its extended tunnel length ensures that even the deepest containers (up to 600mm height) pass through each washing stage with adequate dwell time. High-volume centrifugal pumps maintain 0.3–0.7 MPa pressure at every nozzle, penetrating handle recesses, drainage channels, and ribbed bottom grooves that shallow washers cannot reach. The heavy-duty chain conveyor handles payloads up to 50kg per container, making it suitable for fully loaded meat lugs and fish bins.
Every millimeter — frame, housing, spray manifold, chain conveyor, and water tanks — is fabricated from food-grade SUS304 stainless steel. At this scale, lower-grade materials would warp, crack, or corrode under sustained high-temperature, high-humidity operation. Our full stainless build ensures decades of reliable service and full HACCP compliance. SUS316 upgrade available for facilities using aggressive chemical cleaning agents.
Stage 1 – Pre-Wash (40–50°C): High-flow water removes coarse debris, meat particles, fish scales, and loose organic soils.
Stage 2 – Alkaline Wash (65–75°C): Detergent-infused spray dissolves fats, oils, and protein residues embedded in container surfaces.
Stage 3 – Acid Rinse (60–70°C): Neutralizes alkaline residues and removes mineral scale buildup from hard water.
Stage 4 – Final Sanitizing Rinse (75–85°C): Fresh hot water ensures containers are hygienically clean and ready for immediate reuse.
Each tank has its own heating element, filtration circuit, and water level sensor. The recirculation system recovers up to 70% of process water, dramatically reducing utility costs in high-volume operations.
The spray architecture uses a high-density array of fully adjustable 304 stainless steel nozzles — not plastic clip-ons that warp under sustained heat. Each nozzle can be individually angled to target:
Container handle recesses and side-wall ribbing
Bottom drainage channels and corner crevices
Stacking ledges and pallet box base channels
Wire mesh intersections on basket-style containers
This custom-tuned spray geometry ensures zero blind spots, even for containers with complex internal geometries.
Operators configure all parameters — conveyor speed (2–12 m/min, VFD adjustable), temperature per tank, pump pressure per zone, and automatic start/stop scheduling — through a waterproof Siemens PLC interface. Multi-language localization (including Russian and Spanish) ensures smooth operator adoption. Real-time fault diagnostics and maintenance alerts minimize unplanned downtime.
All contactors, relays, circuit breakers, and sensors are sourced from globally recognized brands — Schneider Electric, Omron, and Siemens. This ensures electrical stability under 24/7 continuous operation, easy local sourcing of spare parts, and consistent performance in high-humidity wash-down environments.
For facilities requiring immediate container reuse, an integrated air-knife module at the tunnel exit strips over 90% of surface moisture. Containers emerge dry and ready for stacking, storage, or product loading — eliminating the need for a separate drying line.

Meat lug crates, viscera containers, E2/E3 standard Euro meat boxes, shackle carriers, and poultry transport baskets. The 4-stage system effectively removes animal fats and protein residues that manual washing cannot consistently eliminate.
Fish crates, shellfish harvesting bins, ice-filled seafood transport containers, and aquaculture grading trays. The stainless steel construction resists saltwater corrosion, and the high-temperature rinse stage ensures hygienic conditions for raw seafood handling.
Vegetable and fruit transport totes, harvest bins, field crates, and hydroponic growing trays. The adjustable spray pressure allows gentle cleaning for delicate produce containers or aggressive washing for soil-caked field bins.
Reusable plastic pallets (RPCs), warehouse tote bins, picking trays, Euro pallet boxes (1200×800mm), DOLAV-style bulk containers, and stacking distribution crates. The heavy-duty conveyor handles payloads up to 50kg per container.
Milk crate logistics systems, cheese aging rack containers, and keg washing baskets. The 4-stage process with dedicated acid rinse eliminates milk stone buildup and ensures containers meet dairy industry sanitation standards.

Q: What types of containers can the Tindotech industrial crate washer handle?
A: This machine is engineered for deep-sided, heavy-duty containers — including meat lugs, fish crates, Euro pallet boxes (1200×800mm), DOLAV bulk bins, logistics totes, and poultry transport baskets. The extended tunnel length and high-volume pump system ensure thorough cleaning even for containers up to 600mm in height and 50kg in weight. For flat containers like baking pans and drying racks, we recommend our Automatic Tray Washing Machine.
Q: How does the 4-stage washing system differ from a standard 3-stage washer?
A: The additional stage — a dedicated acid rinse between the alkaline wash and final sanitizing rinse — neutralizes detergent residues and removes mineral scale buildup from hard water. This is critical for facilities processing fatty products (meat, fish) or operating in regions with hard water. It also extends the service life of the heating elements and spray nozzles by preventing scale accumulation.
Q: Can this machine handle containers with wire mesh or perforated walls?
A: Yes. The adjustable 360° stainless steel spray nozzles can be individually angled to target wire mesh intersections, perforation patterns, and basket handle attachment points — areas where debris typically accumulates and manual cleaning struggles to reach.
Q: Is installation and maintenance support available internationally?
A: Absolutely. Tindotech provides detailed installation manuals with multi-language support, remote video guidance during assembly and commissioning, and 24/7 engineering support. For large-scale installations, on-site commissioning by Tindotech engineers can be arranged. All maintenance points are designed for toolless access — daily filter inspection, weekly nozzle check, and monthly heating element verification.
In July 2026, Tindotech shipped our largest-ever 6.5-meter tunnel washing system to a major Russian food processing facility — our third industrial washer delivery to Russia this year. The system handles 800–1,200 crates and trays per hour with a 3-tank recirculation system, Siemens PLC automation, and full SUS304 construction. Read the full case study →
