A meat plant’s wash-room: immersion cleaning at audit standard

The CM-800 custom-built installation taking racks, saw components and smallgoods equipment through a staged ultrasonic clean — photographed in service.

5 min readBy Misonics application engineers

A meat processing plant runs on equipment that must be genuinely clean — not visually clean — on a schedule that never pauses. This study documents a custom-built industrial ultrasonic installation (CM-800) taking racks, trays, saw components and smallgoods equipment through a staged clean at food-plant standard.

The contamination

Animal fats and proteins

The daily load — films that harden with temperature cycles and shield bacteria from sanitisers if they survive the wash. Saponifying alkaline chemistry territory.

Carbonised residue

Ovens, smokehouse racks and cookers bake fats to carbon that pressure washing polishes rather than removes.

The hygiene standard

In an export-registered plant, "looks clean" is not a standard. Equipment must be cleanable to audit, on schedule, every day — which is a process argument, not a labour argument.

The results

Audit-standard cleanliness on schedule. Immersion cleaning reaches the mesh, hinges and weld seams that fail swab tests after manual washing.
Labour redeployed. The scrubbing crew becomes a loading crew — hours per shift return to production tasks.
Equipment life extended. No more aggressive manual scraping and pressure-lance damage to coated and welded surfaces.
Sanitiser that works. Sanitising chemistry applied to genuinely clean surfaces performs as specified — the step most plants unknowingly waste.

FAQ

Questions about this process

What does the installation clean?
Racks, trays, saw components and smallgoods equipment, immersed whole, through a staged ultrasonic wash, hot rinse, sanitiser stage and return, on a CM-800-class custom-built system.
What is the standard it has to meet?
Export-plant hygiene. In an export-registered plant, looks clean is not a standard; equipment has to be cleanable to audit, on schedule, every day.
Why ultrasonics rather than pressure washing?
Smokehouse racks and cookers bake fats to carbon that pressure washing polishes rather than removes. Hot alkaline chemistry saponifies the fat and cavitation lifts the carbon, so the sanitiser is applied to a surface where it can work.
