Automatic Tray Washing Machine | Industrial Pallet & Box Washer | TINDO

Product Introduction: The Tindotech Automatic Tray Washing Machine is a high-efficiency tunnel cleaning system purpose-built for food processing plants, commercial bakeries, and logistics centers. Unlike deep-crate washers designed for bulk bins, this machine is specifically optimized for flat and shallow containers — including baking pans, drying racks, IQF pallets, and plastic storage trays.

Equipped with a 3-stage washing process and a high-density spray nozzle array, it delivers consistent, hygienic results at a throughput of 800–1,200 units per hour. Constructed entirely from SUS304 stainless steel and fully CE certified, this machine meets the rigorous sanitation standards of HACCP-compliant food 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 engineering capability at any scale. Read the full case study →

Designed for Thin & Flat Containers

Unlike crate washers built for deep bulk bins, the Tindotech Automatic Tray Washer is engineered for flat trays, baking pans, drying racks, and IQF pallets. Its closely spaced spray nozzles ensure scrubbing pressure is concentrated on surfaces with shallow depth, guaranteeing a spotless finish even for stubborn baked-on sugar and grease residues. The adjustable guide rail system accommodates various dimensions in a single pass — from small pastry molds to full-size Euro pallet boxes.

Key Features of Our Automatic Tray Washer

Full SUS304 Stainless Steel Construction

Every component — from the structural frame and outer housing to the internal spray manifold and chain conveyor — is fabricated from food-grade SUS304 stainless steel. At sustained high temperatures and humidity, lower-grade steel would warp and corrode. Our full stainless build ensures zero corrosion, full HACCP compliance, and decades of reliable service.

3-Stage Washing System with Independent Tank Control

• Stage 1 – Pre-Wash (40–50°C): High-flow water removes coarse debris, flour dust, and loose organic soils.

• Stage 2 – Main Wash (65–85°C): Detergent-infused high-pressure spray dissolves baked-on sugars, grease, and protein residues.

• Stage 3 – Final Rinse (75–85°C): Fresh hot water sanitizes surfaces and prepares trays for immediate reuse.

Each tank has its own heating element, filtration circuit, and water level sensor. The recirculation system recycles up to 70% of process water, dramatically reducing utility costs.

Adjustable 360° Stainless Steel Spray Nozzles

The spray architecture uses a high-density array of fully adjustable 304 stainless steel nozzles — not the plastic clip-on nozzles found on budget machines that warp under sustained heat. Each nozzle can be individually angled to target tray edges, corner recesses, stacking ledges, and bottom grooves, ensuring zero blind spots across the entire tunnel.

Siemens PLC Control with IP65 Touchscreen HMI

Operators configure all parameters — conveyor speed, temperature per tank, pump pressure, and cycle scheduling — through a waterproof Siemens PLC interface with multi-language support. Real-time fault diagnostics and maintenance alerts minimize downtime.

Optional Air-Knife Drying Zone

For facilities requiring immediate tray reuse, an integrated high-velocity air-knife module at the tunnel exit strips over 90% of surface moisture, delivering trays ready for stacking or product loading without a separate drying line.

Technical Specifications

Frequently Asked Questions

Q: Can this machine wash different sizes of trays and baking pans?

A: Yes. The adjustable guide rail system accommodates various dimensions — from small pastry molds and bun pans to full-size Euro pallet boxes (1200×800mm). The closely spaced spray nozzles ensure effective cleaning across all sizes in a single pass.

Q: How does the 3-tank system reduce water and energy costs?

A: Each tank operates independently with its own filtration loop. Tank 1 handles coarse debris, Tank 2 recirculates detergent-infused hot water, and Tank 3 provides fresh hot water for final rinsing. This cascading design recovers up to 70% of water for reuse — in a facility washing 5,000+ trays daily, the savings on water and heating energy are substantial.

Q: Is the machine compliant with international food safety standards?

A: Absolutely. The entire machine is constructed from food-grade SUS304 stainless steel and is fully CE certified. Its open-frame design and accessible spray zones allow for thorough high-pressure washdowns, meeting HACCP and European food safety audit requirements.

Proven at XXL Scale

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 →
