NUMAFA

• Washing and sanitising plastic crates and containers (e.g., E2 Euro-crates) in food logistics.
• Cleaning bakery and confectionery moulds, trays, and sheets.
• Sanitising stuffing trolleys and other small to medium-sized food processing equipment.
• Washing plastic and aluminium pallets in high-throughput environments.
• Hygiene maintenance for reusable packaging in various industrial sectors.

Typical throughput

Units of this class commonly process hundreds to over a thousand items per hour, depending on item size and wash cycle requirements.

Construction material

Typically full stainless steel (e.g., AISI 304 or 316) for hygiene and corrosion resistance, essential for food contact applications.

Power supply

Commonly requires a 3-phase industrial electrical supply, typically 400V, 50Hz, with varying power consumption based on heating and pump motor sizes.

Water heating

Often features electric or steam heating elements to maintain wash water temperature, typically up to 85°C.

Drying method

Units of this type commonly employ high-velocity air knives or blowers for efficient water removal post-wash.

Footprint

Industrial tunnel washers typically have a significant linear footprint, often ranging from 4 to 10 metres in length, plus access space.

Control system

Commonly includes a PLC-based control cabinet with HMI for managing conveyor speed, water temperature, pump pressure, and safety functions.

Industrial washers for food processing are valued for their reliability and durability when purchased used. Buyers typically seek machines with accessible spare parts and straightforward maintenance records. Common strengths include robust construction, consistent cleaning performance, and long operational lifespans. When evaluating used units, inspectors should verify spray arm condition, verify seal integrity, and confirm compliance with food safety standards. Well-maintained examples often deliver strong value, though buyers should confirm previous sanitation protocols and operational history before purchase.
