Ask three food production kitchens what they need and you will hear three different sentences that mean the same thing: the hood filter is blocked again, the floor near the fryer stays slippery after mopping, the night crew gives up on the burnt trays. A supplier reading that sentence cannot choose a model yet. What decides the quotation is not the complaint but the conditions around it — power, water, drainage, access, time available, and what kind of soil is being removed.
The list below is what an equipment supplier needs before a quotation can be trusted. Most of it can be collected in one afternoon by walking the site with a notebook and a phone camera, and every item changes something concrete in the price and in the machine that arrives.
Start with the operation, not the room
A 300-square-metre central kitchen supplying airline meals and a factory canteen serving one lunch shift do not need the same equipment, even if both are described as "a commercial kitchen". Tell the supplier what is being produced, roughly how much, and how the day is organised.
- Type of operation: commissary or central kitchen, ready-meal line, institutional canteen, bakery, processing plant with an in-house kitchen.
- Shift pattern and whether production stops during cleaning, or continues a few metres away behind a partition.
- Who does the cleaning: a dedicated sanitation crew on nights, or line cooks at the end of their shift with whatever time is left.
- What is used today, and what is wrong with it. A supplier who knows you already own a cold-water pressure washer and a drum of alkaline detergent is not going to sell you the same thing at a higher price.
This part matters because it fixes the duty cycle. Equipment sized for one operator working forty minutes after service is a different class of machine from equipment expected to run continuously through a four-hour sanitation window.
Name the soil and the surfaces
"Grease" covers several different problems. Rendered animal fat softens with heat and re-solidifies when it cools in a duct. Burnt sugar and starch from sauces and frying char onto a surface and need to be softened before any force is applied. Protein residues from stock and dairy set with heat in one stage and release in another. Flour dust mixed with oil becomes a film that water alone spreads rather than removes.
Send a description of each location, and photographs of the deposit in its worst condition:
- Range hoods, grease filters, exhaust ducts and fans.
- Griddles, fryers, tilting pans, ovens, combi steamers, braising kettles.
- Floors, drains, gullies and the corners where equipment stands are bolted down.
- Racks, trolleys, GN pans, trays, containers, and the walls and ceiling directly above cooking lines.
Then state the materials. Grade 304 stainless is one thing; galvanised sheeting in an older duct, painted steel frames, tile with porous grout, epoxy flooring and its age, and sealed concrete all respond differently to heat and pressure. This is the detail that decides whether a food industry cleaning equipment range should be configured around dry steam, wet steam or hot water, and how much of each the machine has to deliver.
Give the site conditions as numbers
A configuration that cannot be powered, fed with water, or carried into the room is not a configuration. Put the following in the enquiry:
- Electrical supply at the outlet nearest the cleaning area: voltage, single or three phase, socket type, and whether the circuit is shared with cooking equipment. A fixed machine drawing several kilowatts of heating power is a different installation from a battery unit that has to be charged somewhere else.
- Water supply at the point of use, whether it is tap water, and the inlet fitting size. Send a photo of the tap and its thread.
- Drainage: where floor drains are, how the floor falls toward them, and whether wash water from the cooking area is allowed to run to them under your own procedures.
- Access and storage: door widths, steps, lifts, the distance from the utility point to the far end of the kitchen, and where the machine will live between cleans.
- Environment: indoor or outdoor, and ambient temperature in winter if cleaning starts at a loading dock or in a yard.
Read a specification sheet the same way you would want it read for you. The published data for our fixed machine PowerDe HW02, for instance, gives a 220 V supply, 6 kW heating power, an 80 L tank in grade 304 stainless, a steam temperature around 160 °C and a working pressure of 0.8 MPa. Voltage decides whether the site can run it at all. Heating power decides how fast it reaches working temperature and how long it holds there. Tank volume and pressure decide how far a single operator gets before stopping for a refill.
Quantify the workload and the cleaning window
Three numbers do most of the sizing work: the floor area to be cleaned, the count of items that need degreasing (hoods, filters, duct runs, fryers, racks), and the minutes available between production and the next morning's prep. Then say how often each job happens — the surfaces wiped down daily, the deep degrease each week, and the strip-down of ducts and fans once or twice a year.
A short video of one cleaning session, filmed on a phone, tells a supplier more than a written paragraph. It shows how many people are involved, how long each stage takes, and where they are fighting the equipment rather than the dirt.
Also state which items can be moved out of production for cleaning and which have to be cleaned in place. That single answer can be the difference between a mobile unit and a fixed installation.
State the hygiene, safety and audit requirements
Tell the supplier which scheme you are audited against and what the auditor looks at in the sanitation record. If your procedure includes a heat step or a swab check after cleaning, say so, because it changes what you need the machine to do at the end of a pass rather than during it.
If the aim is to use fewer chemical detergents — usually for rinse-water reasons, product contact risk, or the labour of the rinse itself — say that explicitly. High-temperature steam and hot water carry much of that work with heat instead of chemicals, and less rinse water to manage afterwards.
Finally, put the working conditions in front of the supplier: wet floors, hot surfaces, an operator working alone at night, water and electricity in the same room. Ask what protections the machine has for leakage, short circuit, over-temperature and running without water, and ask how the operator is warned. A kitchen machine will be used by whoever is on shift, not by a trained cleaning contractor, so controls have to be obvious.
Cover the commercial scope before the first price
- Quantity, and whether the second and third units are part of the plan for the next site.
- Spare parts and consumables: nozzles, hoses, seals, filters, and their prices as a separate list, not bundled invisibly into the machine price.
- Battery or mains. A battery unit can move between floors and start before anyone pulls a cable, but it needs a charging place and spare packs, and its run time has to cover your cleaning window.
- Warranty terms, who services the machine, how fast a technician responds, and whether spare parts are stocked in your country or shipped from the factory.
- Training, the language of the manual, and the documents you need for import and customs.
- Lead time, delivery terms and destination port, and the date by which the equipment has to be running.
If nothing in the standard range fits the site, say so and let the supplier answer with an engineering option, since customized steam cleaning equipment is normally justified by a workload or a layout problem rather than by preference, and that is exactly the case a good supplier should recognise from the answers above.
What a serious supplier does with this information
They come back with questions instead of only a price. They point out which of your numbers still need measuring. They recommend a model, and they say plainly when the standard range does not fit and what would have to change — then they tell you what is not included in the quotation.
Before any order, ask for a test you can verify. Send a badly soiled hood panel, a section of duct or a burnt tray and see what arrives back, or trial one machine on one line for a week and compare the hours spent. Shenzhen PowerDe has been an intelligent cleaning equipment manufacturer in Shenzhen since 2007, with product development, hardware testing and engineering services run from the same workshop that builds the machines, so a trial on your own parts is something to expect rather than negotiate for.
Send the specification, the photographs, the video and the numbers, and a comparison of quotations stops being a comparison of prices. You end up comparing three answers to the same question, which is the only condition under which the cheaper machine is a decision rather than a gamble.
