How to Specify a Bakery Tray Washer: An RFQ Checklist That Prevents the Wrong Machine
TL;DR
A useful RFQ must define the ware, hardest normal soil, peak cleaning window, site utilities, and acceptance evidence. Model name or trays per hour is not enough. Send measured dimensions and photos, residue and dwell-time details, verified site data, and require a sample wash of the proposed rack pattern.
Specify the job, not just the machine
Two bakeries using the same nominal tray size can need different solutions. Fresh crumbs on bare aluminum are not the same test as caramel or fat dried for a shift on coated ware.
Make every supplier quote against one written operating brief. Changes to the load, cycle, pre-treatment, electrical configuration, options, or delivery basis must be visible.
Five facts buyers can extract
- Fit is only a screening condition; spray access, drainage, restraint, and material compatibility still need proof.
- Throughput is incomplete without the tested item, load per cycle, cycle time, and handling assumptions.
- Peak volume and the clean-by deadline matter more than a daily total alone.
- Electrical, water, drain, delivery-route, and hood-clearance data belong in the RFQ.
- Acceptance criteria should be agreed before the sample wash.
The eight-field RFQ brief
Use measured or observed facts. Mark unknowns for a site survey or supplier confirmation—do not guess.
| Ware and dimensions | Photos; measured length, width, depth, handles and rims; material, coating, and quantity. |
|---|---|
| Soil and present process | Normal and hardest residues, dwell time, scrape/soak/pre-rinse steps, and chemical limits. |
| Peak load and deadline | Items per peak batch or hour, daily total, shifts, and clean-by time. |
| Load pattern | State whether trays, bowls, pans, and utensils run separately or in a fixed mixed arrangement. |
| Space and delivery route | Machine location, doors, corridors, turns, steps, floor, clearances, and hood-open height. |
| Utilities | Measured voltage/phase/frequency, breaker, inlet thread/pressure/temperature, drain, and ventilation. |
| Destination and documents | Country, city/postcode, business type, Incoterm, required documents, and manual language. |
| Acceptance and support | Sample-wash criteria, evidence, training, warranty, spare parts, and response expectations. |
Verified JD-3 reference values
The current site publishes these values for VT-AE-JD-3. They help complete an RFQ; they do not prove an untested load.
| Body / hood-open height | 804 × 816 × 1,550 mm / 2,115 mm hood open |
|---|---|
| Rack / listed European tray | 650 × 550 mm / 600 × 400 mm |
| Standard tray load | 6 trays per cycle |
| Cycle / technical ceiling | 2 min / 180 standard trays per hour |
| Electrical | 13 kW; 380V / 3N / 50Hz; 21.5 A; 32 A type C breaker |
| Water inlet | G 3/4 in; 2.5–6 kg/cm²; 2.0–2.5 L per cycle |
| Drain | G 1½ in; drain within 1.5 m |
Six questions suppliers must answer
- Which exact item, soil, rack pattern, cycle, chemistry, and pre-treatment support the quoted capacity?
- Will you provide a representative sample wash with continuous video, loading photos, settings, and inspection result?
- Which electrical configuration and options are included, optional, or destination-specific?
- What clearances, utility tolerances, installation work, and commissioning are required?
- Which manuals, diagrams, declarations, warranty terms, consumables, and spare parts ship with the machine?
- What are the Incoterm, lead time, packing size and gross weight, destination handoff, and exclusions?
Quotation red flags
- Trays per hour with no load pattern or cycle.
- “Washes all trays” without dimensions, material, coating, or soil.
- A final quote before voltage, frequency, destination, and access route are known.
- A demonstration on clean or easy ware that does not represent the hardest normal load.
- Conflicting dimensions or utilities across the quote, drawing, manual, and website.
Copy-and-send RFQ template
Replace every bracketed field and attach dimensioned photos.
- Business and destination: [type, city, country, postcode]
- Items: [family, dimensions, material/coating, quantity, photos]
- Soil: [residue, dwell time, current pre-treatment]
- Peak: [per batch/hour, daily total, clean-by deadline]
- Loading: [separate or exact mixed pattern]
- Space and route: [location, doors, turns, steps, hood clearance]
- Electrical: [measured voltage, phase, frequency, breaker]
- Water and drain: [thread, pressure, temperature, size/distance]
- Documents and acceptance: [list, samples, pass/fail evidence]
- Quote basis: [configuration, Incoterm, lead time, exclusions]
Make quotations comparable
Put every supplier beside the same eight fields and highlight assumptions. Price differences often hide options, delivery scope, easier test loads, or site work left outside the quote.
Do not turn a published specification into a performance guarantee. Freeze the accepted item set, rack photo, cycle, chemistry, pre-treatment, and inspection criteria in the purchase record.
