What actually has to be cleaned on the outside
In a butchery, boning hall or further-processing room, the exterior duty is a short and repeatable set of tasks. Skinned, welded and painted frames collect splash. Stainless guarding and drip trays hold films of fat. Feet, floor mounts and the band around a motor housing collect build-up that nobody can see without bending down. On saws, deboners and fillers, the housing around the working head picks up the same material in a thinner layer but far more often.
The practical target is a surface that is visibly free of film, dry enough to leave no standing water on the floor, and free of the fat that a hot-water hose alone will only move around rather than remove. That target sets the equipment list: something to heat water, something to lift the grease off the metal, something to recover the run-off, and something to reach the low and awkward places without a person climbing.
The equipment list, item by item
1. A steam and hot-water machine that switches between modes
The centre of the job is a machine able to run dry steam for loosening baked-on fat on a vertical face, and hot water for flushing the emulsified soil away afterwards. On PowerDe's fixed unit, the published parameters cover a 6 kW heater, steam at 160°C, vapour pressure of 0.8 MPa and an 80 L stainless tank, with a switch between dry and wet steam. A fixed steam cleaning machine of that type stands on castors next to the line, runs from a 220 V supply and takes its feed from a tap, so it does not need a dedicated water point plumbed in.
Why the steam mode matters in a cold room: dry steam carries heat with very little free water. On a frame in a chilled environment, that means the surface is hot enough to release the fat without flooding the floor and creating the slip problem the wash-down was supposed to remove.
2. A lance, a nozzle set and a brush head
The machine moves the energy; the tool on the end decides whether it reaches the surface. A straight lance handles open frames and guarding. A short angled nozzle covers the underside of a channel. A brush head does the work a jet cannot: it breaks the film on painted or brushed surfaces, on weld seams and around bolt heads, where the residue grips mechanically rather than chemically. Ask your supplier which heads ship with the unit and which are optional, because that list is usually the difference between a machine that works on day one and one that needs a second order.
3. A vacuum system for the run-off
Recovering the loosened soil is the least glamorous and most consequential part of exterior cleaning. Left on the floor, a film of fat and protein becomes a slip hazard and a re-contamination route back onto the line. PowerDe's fixed unit is offered with a vacuum cleaner as part of the cleaning method, and hand-pushed units are listed for cleaning and disinfecting hospital beds and medical machinery, which is the same discipline applied in a different building. Where no vacuum is fitted, plan for squeegees, absorbent mats and a drain route decided before the water goes on.
4. Mobile units for machines that cannot be moved
When the equipment is bolted down and the wash-down has to walk to it, a battery-fed unit removes the cable and water-point problem. PowerDe's hand-pushed hand-pushed steam cleaning machine runs its working supply from a 48 V battery, moves by hand, carries a 50 L clean-water tank and heats with a 4.5 kW PTC element. The published sheet does not state steam temperature, steam pressure, battery capacity or run time, so treat those numbers as questions for the manufacturer rather than facts to write into a specification.
5. Consumables, storage and the safety layer
- Sealed electrical connection rated for a wash-down area, plus a residual-current protective device on the supply being used.
- Gloves, a face shield or safety glasses and closed footwear rated for wet floors. Steam at 160°C burns in a fraction of a second.
- A written cleaning sequence for each machine type, with the order of tasks fixed so the same person does not improvise differently every week.
- Dedicated tools for the exterior task, kept apart from tools used on product-contact surfaces, and stored off the floor.
Choosing the machine: what to decide before you ask for a quote
Three decisions settle most of the specification, and they are better settled by the plant than by the seller.
- Fixed or mobile. A fixed unit on castors suits a line washed down at a planned time from one point. A battery-fed hand-pushed unit suits a wide room with several machines spread apart and no useful cable run.
- Steam only, or steam plus hot water. If the soil is mostly fat, the steam mode does the lifting and the hot-water flush clears it. If the soil is mostly dried protein and blood, the flush matters more, and tank capacity sets how long one fill lasts.
- Cold room or ambient. This decides how much free water the floor can take, and that answer points at the dry-steam mode.
Two more points are worth writing into the enquiry. First, protection features. The fixed HW02 page lists leakage, short-circuit, high-temperature, high-voltage and water-shortage protection among its features; the site's wording on how many are fitted has varied between pages, so ask the manufacturer to confirm the list for the unit being quoted instead of relying on a count. Second, power. A 6 kW fixed unit and a 4.5 kW heated unit both need a supply that exists where the work is done, and in an older hall that is often the real constraint rather than the machine.
How the task is usually run
A workable routine for a boning hall keeps to four passes. Dry steam is applied first to vertical faces, guarding and housings, working from the top of the machine downwards so loosened material falls onto areas not yet done. The brush head follows on seams, bolt heads and painted surfaces. Hot water then flushes the emulsified soil into the recovery route. The vacuum or squeegee clears the run-off, and the machine is left drying before the next shift starts. Frames and floor mounts get the same pass; they are the part most often skipped because they sit below eye level.
For a first trial, one machine and one shift is enough evidence. Take the machine with the worst exterior build-up, run the four passes, and compare what the operator had to do by hand before with what is left afterwards. That comparison tells you more than a brochure.
Where the supplier conversation should go next
PowerDe is a Shenzhen-based manufacturer of cleaning equipment alongside its automation and process equipment work, so an enquiry for industrial steam cleaning equipment reaches the team that builds and tests the machines rather than a reseller. Bring photographs of the two or three machines that give you the most trouble, the room layout, and the supply available at the point of work. Where a standard unit does not fit the hall, the same route covers customized steam cleaning equipment built around your line.
Before signing anything, ask for the parameters of the exact model in writing: steam temperature and pressure, tank capacity, working voltage, battery run time if the unit is battery-fed, and the accessory list. A quotation that answers those points is a quotation you can compare. One that does not is a question still open.
