NUMAFA - 2004 NUMAFA Crate washer

• Cleaning and sanitising reusable plastic crates in food processing environments.
• Washing containers in logistics and distribution centres.
• Hygiene maintenance for produce trays in agricultural packing houses.
• Sanitising bakery trays and confectionery moulds.

Typical throughput

For this class of equipment, throughput can typically range from 200 to over 1000 crates per hour, depending on the wash cycle and crate size.

Suitable feed size

This unit is specified for 400x600mm boxes. Numafa crate washers commonly handle standard European crate dimensions.

Power supply

Units of this type typically require a 3-phase electrical supply, commonly 400V, 50Hz, with varying power consumption depending on heating elements and pump sizes.

Water consumption

Water consumption for crate washers is typically optimised, often incorporating recirculation systems, with fresh water top-up rates varying based on soil load and desired hygiene levels.

Heating method

Water heating is commonly achieved via electric elements, steam injection, or gas burners, depending on the specific configuration and available utilities.

Footprint

The overall footprint for a crate washer with an output conveyor can vary significantly, but typically requires a linear space of several metres, plus access for maintenance.

Construction material

Crate washers are typically constructed from stainless steel (e.g., AISI 304 or 316) for hygiene and corrosion resistance in wet environments.

• What maintenance is typically required for a used crate washer?

  Regular maintenance typically involves cleaning filters, checking nozzles for blockages, inspecting pumps and motors, and monitoring conveyor belt tension and wear. Gaskets and seals may also require periodic replacement.

• Can this unit handle different crate sizes?

• What is the purpose of the 'separator + cleaning blower'?

• Is installation support typically available for used equipment?

• What are the typical safety features on a crate washer?

For food processing washing and sanitizing equipment, buyers typically value durability, ease of cleaning, and compliance with hygiene standards. Industry sentiment emphasizes the importance of verifying spray patterns, material quality, and maintenance history when purchasing used units. Stainless steel construction and reliable pump performance are considered key strengths. Buyers should check for corrosion, seal condition, and documentation of regular servicing to ensure food safety compliance.
