Hold temperature through the full shift.
A processing room can hold temperature empty at 6am and drift warm by lunch. People, lights, saws, slicers, conveyors, and opening doors all add heat while exposed product is on the floor. We build +50 to +65°F rooms for cutting, portioning, packing, and staging. Load, airflow, washdown, and layout get sized around the actual shift, then serviced for life.
What the room has to carry
| Cold processing room | |
|---|---|
| Operating temp | +50 to +65°F (+10 to +18°C) — staff-tolerable, product-safe |
| Design type | Positive cold room (above freezing) |
| Panel | 100mm high-density PIR standard (75–120mm by ambient) |
| Door | Sliding, forklift-width (example 6.5 × 7.9 ft) or two-way swing between zones |
| Refrigeration | Copeland condensing unit in the +10 to +20°C design band; double-sided-blow air coolers |
| Floor | XPS (250 kPa) + SBS waterproofing + vapor barrier; drains and slope for washdown |
| Controls | Schneider panel — phase, over/under-voltage, overload; remote monitoring standard |
Size it for the busiest hour
- 01Count the working heatMotors, lights, bodies, and door traffic can dominate the load. We calculate the room at 2pm on a full shift, not at 6am before the equipment starts. That's the difference between holding temperature and chasing it. How we size it →
- 02Air without a wind tunnelDouble-sided blowing air coolers spread air softly and evenly. The crew shouldn't work in a constant draft, and exposed product shouldn't dry on one side because an evaporator throws too hard down one aisle.
- 03Built for nightly washdownStainless 304 or color-plate skins, sealed joints, coved corners, sloped drains, and a floor built for pallet jacks and hose-down. The surface choice changes wall by wall, depending on water and product contact. Panel options →
- 04Doors people can useTwo-way swing doors with vision panels fit hands-full movement between processing zones. Sliding doors keep forklift lanes clear. The right door protects temperature because the crew can move through it without hitting it or propping it open. Door types →
The shortest product path usually wins.
Every extra turn between receiving, staging, processing, freezing, storage, and shipping adds handling and time outside temperature control. A drain, a door, or a blast freezer on the wrong side of the room stays wrong for years.
We ran a food plant for 20+ years. We lay out the cold around the process, install everything we sell, and service it for life. The refrigeration matters, but the product path decides whether the room works every day.
Questions we answer every week
What temperature should a cold processing room be?
Most run at +50 to +65°F (+10 to +18°C). That's cold enough to keep product in its working specification and warm enough for a crew to work a full shift. Seafood and poultry generally sit near the low end. Chocolate and butter are set around their handling window. It's a positive cold room above freezing, so it doesn't need a freezer floor or freezer-style defrost. The product specification still decides the final setpoint.
Why does a processing room need more refrigeration than storage?
A storage cooler is driven mainly by the panel envelope, incoming product, and occasional door traffic. A processing room adds saw and slicer motors, conveyors, lighting, a full crew, and doors opening throughout the shift. Size it like storage and it looks fine before production, then drifts warm by lunch. We calculate the occupied shift, equipment schedule, product load, and door cycles together. The room has to hold at its busiest hour, not only overnight.
What wall and floor finishes do I need for washdown?
Stainless 304 where walls get hosed or can touch product. Color-plate steel can work on dry walls. Panel joints and corners have to be sealed and coved so water can't reach the foam. The floor needs proper slope and drains over the XPS insulation and waterproofing build. A washable skin doesn't fix a flat floor or an open joint, so we coordinate the room envelope and the drainage together.
Where should the processing room sit in the product flow?
Product should move in one direction: receiving, cold staging, processing, blast freezing or chilling, walk-in storage, then shipping. The processing room belongs where that path stays short and raw and finished traffic don't cross. Door types follow the movement between zones. This is building-specific; an ideal diagram that ignores columns, drains, docks, and ceiling clearance isn't useful. We map the real building before fixing the walls and openings.
