Start with the zones, not the catalogue
A brewery floor is not one surface with one problem. The brew deck, the tunnel and cooling area, the filling and packaging hall and the pallet route each hold a different deposit, a different amount of standing water and a different window of time between runs. Before anyone prices a machine, walk those zones and write down what is on the floor, how wet it is, where the nearest water and power sit, and how long the crew has once production stops. That short survey is the specification. A catalogue list cannot know that your packaging hall stays dry while your brew deck does not.
Floor work in a brewery usually shares a shift with washdown of the tank outsides, stands and conveyors that discharge onto that floor. The floor sets the method; those surfaces set the reach and the accessory set. Keep both in the survey, and keep them separate on the quotation.
Brewery floor and equipment cleaning
What the floor is actually holding
Three families of soil behave differently, and the family decides how much effort the crew repeats.
Sugary and protein films
Spilled wort, syrup, yeast carry-over and splash from transfers dry into a tacky film that binds grit into itself. While wet it is slippery; once dry it is glued. A cold rinse removes the loose part and leaves the film behind. A warm or hot rinse is what softens it so the next pass can lift it. This is the soil most often under-reported, because a rinsed floor looks clean while the film is still there.
Fats and lubricants
Conveyor gearboxes, pallet trucks, wheels and tyre tracks leave an oily layer, thickest in the lane that people and trucks cross repeatedly. Oil does not rinse away, it spreads, and it turns a hard deck into a slip risk the moment water runs over it.
Mineral and dust build-up
Malt dust and grit, plus dried hard-water residue around drains and splash zones, settle into the texture of the deck and into joints. It is not sticky, but it is what leaves a floor looking grey after the wash has finished.
The ladder: the cheapest tool that clears the soil
Most sites already own the first rungs, and they should be used first because they remove the bulk of the load fast.
- Squeegee first. The most useful floor tool in a wet area. Standing water and loose solids go toward the drain before any wash begins, and every later step gets shorter.
- Stiff brush, and a hand spray with cloths. For base corners of tanks, feet, stands, kerbs and anywhere the squeegee cannot reach.
- Pressure washing. Effective on grit, dust and open stretches of a sealed deck. It uses a great deal of water, it throws spray and mist across the aisle, and by itself it does little to a bonded oily or sugary film.
- Heat. Hot water and steam shorten the time the crew must wait for a film to release. High-temperature steam work runs on comparatively little water and more heat, which suits areas where flooding the deck is a problem and where the soil is a film rather than loose dust.
On a tiled deck, put the attention on the joints. Grout lines and the perimeter junction are where a film hides. A jet alone can blow loose material out of a joint and leave the walls of it coated, so brushing the joint before the rinse is what changes the result.
Then choose portable or fixed by distance and dwell
Two questions decide the machine, and neither of them is about power.
- How far does the unit travel, and how often must it be refilled? On a long deck, a unit that moves with the work and carries its own supply saves more time than a larger machine parked at one end, because the crew stops refilling less often.
- Where are power, water and drainage, and is there a defined wash area? A bay holding the right circuit, a water supply and a drain the site will allow can host a permanent installation that serves several tasks around it. Park the same machine in an aisle without those services and it becomes an obstruction.
A mobile steam cleaning machine suits a line where the floor tasks travel from one end to the other and the services are thin on the ground. A permanent unit suits a defined area where the services already exist. Where the aisle widths, the tank layout or the shift window do not fit a standard arrangement, customized steam cleaning equipment is the route to ask about.
Utilities: the part left out of the enquiry
Ask each bidder to confirm the following in writing, against your own drawing of the area rather than theirs.
- The electrical supply and circuit at the position the machine will be used, not merely at the door of the building.
- The water inlet: fitting type and thread, whether the site supply can feed the unit, and whether a hose must cross a walkway to get there.
- Water hardness at your tap. Scale inside a heating unit is a running cost, and a treatment plan is cheaper than a replacement part.
- The run-off: where the wash water goes, whether it carries product and cleaning chemical, and who owns that waste stream afterwards.
- Cable routing across a wet aisle, and where the crew stands and walks while the work is underway.
Trial one strip and judge it once dry
Mark a short strip in the worst zone, photograph it, clean it with the candidate setup, then let it dry fully. Inspect it in the same light the crew works in and compare it with the photograph. Then ask someone who never held the lance whether they can see the difference.
Define the pass before the trial, not after it. Write the acceptance as a line the crew can test: the film has not returned inside the interval agreed for that zone, the joint lines read the same colour as the open deck, no residue shows on a clean white cloth dragged across the surface, and the floor is walkable and dry at the end of the window rather than an hour later.
Record what failed as well. If the crew had to repeat a pass, if the supply ran out mid-strip, or if the run-off reached an area that had to stay dry, that is a machine or accessory problem, and a trial is the cheapest place to find it.
Questions to put to every bidder
- Which of our zones does this proposal actually serve, and which does it not?
- For the soil described above, what sequence and what waiting time do you expect, and which accessory makes that sequence practical underfoot?
- Which utility points do you assume, and what changes on our layout if one of them is missing?
- What is excluded from the price, and what would it cost to add later?
Send the same zone survey and the same soil description to every bidder. Once the answers are written against the same facts, the comparison gets short.
