02.2 — Application
Continuous wash-down, solids on the floor.
A line that runs all shift with water on the floor, product on the grate and a cleaning crew that works around the equipment. Here the drain is process equipment, not plumbing.
The floor conditions
- What lands on the floor: wash water, product debris, packaging fragments, cleaning chemistry, and hot water at shift change.
- Flow shape: near-continuous, spiking at wash-down and at CIP discharge.
- Cleaning regime: shift-by-shift, often with foam and a rinse; chemistry varies by plant.
- Who inspects: the plant's own QA against HACCP-based procedures, plus retail audits.
How it fails
- A body with a folded seam: the seam is where the swab comes back positive.
- A grate the cleaning crew cannot lift alone — it stays down, and the channel below it becomes a reservoir.
- 316 quoted as a hygiene measure. It is a corrosion measure; the geometry is what gets cleaned.
What we specify
- Long run under a line → WASH with SS400X rail where a pallet truck crosses.
- Collection point at the low corner → SUMP with high-capacity basket and drive-over grating.
- Cold room, days between washes → TRAP with a dry-trap cartridge, said out loud at quotation.
- Multi-line hall → one outlet per run, not one per hall.
What to send
- Layout with falls and the outlet positions marked
- Pallet truck or racking loads, if any
- Cleaning chemistry and temperature
- Where the floor drains to, and whether it is sampled
Structure only — not published
- Plant photographs — none released yet
- Load class per grate, once tested
