Watson Backus Machinery (UK) - Watson Backus Sanitising Tunnel

• Sanitising packaging materials and containers before filling in food production.
• Disinfecting small to medium-sized components or tools in pharmaceutical or cosmetic manufacturing.
• Cleaning and sanitising trays, crates, or moulds in bakeries and confectioneries.
• Ensuring hygiene for products entering cleanroom environments.

Typical throughput

Variable, depending on conveyor speed and product size; designed for continuous sanitisation.

Power supply

Commonly 3-phase industrial supply, typically 400V, 50Hz, with control circuitry operating at lower voltages.

Construction material

Predominantly stainless steel (e.g., 304 or 316 grade) for hygiene and corrosion resistance, as seen on this unit.

Sanitisation method

Typically spray-based application of sanitising solutions, often followed by a rinse or drying stage.

Footprint

For this class of equipment, overall length can range from 2m to 5m, with widths around 1m to 1.5m.

Maintenance requirements

Regular cleaning of nozzles, filters, and tanks, along with periodic checks of pumps and conveyor systems.

Suitable product dimensions

Aperture sizes commonly range from 50cm to 100cm in width and height, accommodating various item sizes.

• What types of sanitising agents can be used?

  This type of tunnel is typically compatible with a range of food-grade sanitising solutions, including chlorine-based, quaternary ammonium compounds, or peracetic acid, depending on the material being sanitised.

• Is a drying stage typically included?

• What are the typical water and chemical consumption rates?

• Can this equipment handle different product sizes?

• What safety features are commonly present?

Washers and peelers are considered reliable workhorses in food processing facilities. Buyers typically value models offering consistent performance and easy cleaning. When purchasing used equipment, inspectors commonly assess drum condition, motor functionality, and wear on rotating components. Industry sentiment favours machines with stainless steel construction for durability and hygiene compliance. Straightforward mechanical design generally means lower maintenance costs compared to more complex processing equipment. Availability of replacement parts remains an important consideration for long-term operation.
