Why evaluating the method matters more than buying the machine
Equipment exteriors on a poultry farm — feeder and drinker lines, cage and pen frames, fan housings, conveyor frames, the outside of incubators, trolley wheels and the trackwork that moves everything — accumulate a mixture that ordinary washing does not shift: dried droppings, feed dust bound with moisture, litter dust, and grease at bearings and drive chains. Steam is often proposed for this work because it reduces how much water is applied to a building that must dry before the next placement. The evaluation, however, should be run as a controlled trial on your own equipment, not bought on a datasheet. The steps below are how to run that trial and what to measure.
Step 1: Classify the equipment before choosing a mode
- Electrical items — fan motors, control boxes, wiring runs, sensor housings: never steamed directly; these get wiped, brushed or vacuumed, and are checked for dust and grease accumulation instead.
- Bearing and drive areas: heat liquefies the grease, so steam removes protection along with dirt. These need degreasing deliberately and re-greasing afterwards, which should be written into the method.
- Galvanised frames and wire mesh: generally the easiest category, and where a trial will show the clearest result.
- Painted mild steel and any surface with existing corrosion: steam without prompt drying accelerates rust, so the drying step has to be costed, not hoped for.
Writing these four categories down before the trial is what makes the result readable afterwards. A farm that lumps everything as "equipment" gets a conclusion it cannot act on.
Step 2: Run a side-by-side trial on comparable equipment
Pick two identical units — two feeder trolleys, two fan housings, one half of a pen frame — and clean one with the farm's existing method and one with steam. Keep everything else identical: operator, time of day, water temperature where relevant. Then measure, rather than look:
- Minutes per unit, timed with a stopwatch, including the walking and refilling.
- Water used per unit, and how long the equipment stayed wet afterwards.
- Number of passes needed before the surface was acceptably clean.
- Drying time to a working surface, which is the number that decides whether steam is worth it in a stocked house.
- Visible damage or new corrosion after one week of normal operation, checked at the same points each time.
Step 3: Match the machine to the site's utilities
Most farm trials fail on utilities rather than on cleaning performance. Before the trial, establish what power and water exist at each location and how far the machine has to move between them. That single question usually decides between a mains-fed machine and a self-contained mobile one.
- Where there is a usable supply near the work, a mains machine runs continuously: our Fixed Steam Cleaning Machine PowerDe HW02 operates on 220 V with 6 kW of heating power, around 160°C steam temperature and about 0.8 MPa vapor pressure, an 80 L SUS304 tank, and dry-steam plus wet-steam modes and a vacuum function on one machine.
- Where the work moves along a shed line, a hand-push unit such as the hand pushed steam cleaning machine PowerDe HMW3 carries a 50 L clean-water tank with a 4.5 kW PTC heater and dry- and wet-steam modes, and its 1150 × 520 × 1030 mm footprint is sized for narrow aisles.
- Where a farm vehicle or feed trolley is part of the round, the mobile driving-style units in our PowerDe cleaning equipment series add hot-water mode and are supplied in battery and without-battery versions.
Use dry steam on fan housings, frames and electrical-adjacent surfaces where you want heat with minimal wetting; use wet steam on encrusted droppings and feed-cake, where the moisture is what lifts the deposit.
Step 4: Evaluate against the biosecurity requirement, not against cleanliness alone
- Whether the method gets the equipment to the point where the farm's normal disinfectant can actually contact the surface — organic residue left behind neutralises most disinfectants, and that, not the steam itself, is the argument for the method.
- Whether equipment can be returned to a stocked house within the downtime the farm can afford.
- Whether runoff can be contained and disposed of in line with the farm's own rules; contaminated water moved along a shed line is a biosecurity problem of its own.
- Whether the whole round can be completed by the people the farm already has, in the hours it already allows.
Record every measurement on one sheet per category, and keep it. It is the document that justifies the purchase internally, and the baseline for judging whether the method still works a year later.
Step 5: Confirm what the listings do not state before ordering
Runtime on a battery charge, recharge time, water consumption per hour in each mode, hose and wand lengths, accessory sets and the published steam figures for a specific variant are not all stated on the product pages. Ask us for them in writing for the round you actually run, together with the water inlet arrangement — the published machines take tap water through a 4-point internal-tooth fitting, which needs checking against the farm's taps before the first shift. Tell us the stock cycle, the equipment list and what power and water each shed has, and we will say which model and configuration fits before you spend the money.
