Poultry Rooms Run Wet: Absorbent Pads for Carcass and Portion Thawing

A poultry room asks more of an absorbent pad than a chiller tray ever will. The ambient sits at 8 to 12 °C, the washdown hose runs twice a shift, and crates are stacked, dragged and tipped rather than lifted. Pads that behave perfectly in a 2 °C still room can fail here inside four hours, and the failure rarely looks dramatic — it looks like a wet crate base and a puddle under the pallet. Specifying for this environment starts with what comes out of the bird, not with what the catalogue promises.

Poultry drip is heavier and stickier than red-meat drip

Chilled poultry releases more surface moisture than beef or lamb because much of it leaves the processor wet, and it keeps releasing as the product warms. Plan on 2 to 4 percent of carcass weight as exudate across a full thaw, plus whatever chill water sits in the bag when a vac pack is opened. A crate holding twelve 2 kg birds is 24 kg of product and somewhere between 0.6 and 1.0 litre of liquid, with most of it arriving in the first six hours.

The liquid itself behaves differently. Poultry exudate is protein-rich and foams slightly as it moves across the pad; the foam dries into a thin skin that slows wicking from the third hour onwards. A pad tested on tap water can look spent at hour four while half its capacity is still unused. Look for an open non-woven top sheet that does not collapse under load, SAP loading around 400 to 500 g/m², and a PE back that stops strike-through onto the crate base. A three-ply build with a spunbond top holds up better than a two-ply pad that delaminates when a wet crate is dragged across it.

Size to the crate, not to the gastronorm tray

Most poultry rooms work in 600 × 400 mm stackable crates rather than GN pans. A 580 × 380 mm pad leaves the 10 mm wicking margin on all four sides, sits flat under load, and still leaves the crate’s drainage slots clear. Two smaller pads laid side by side look neater but create a seam down the middle where liquid pools and the base stays wet all shift.

For portion work — thighs, drumsticks, breast fillets in 5 kg bags — a 400 × 300 mm pad under a single layer is usually enough, provided the pieces are spaced 20 mm apart. Stacking is where poultry rooms get into trouble: two layers means the upper layer drips onto the lower one, and the lower pieces sit in a pool the pad never reaches. If throughput demands stacking, a racked draining trolley is the right tool and the pad is not.

Swap intervals track room temperature more closely than pad grade. At 8 to 10 °C, change every four hours and treat the fifth as borrowed time. In a dedicated 2 to 4 °C thaw room, six to eight hours is realistic for a single layer. Put that interval on the wall board as well as in the HACCP file, because the person changing pads is seldom the person who wrote the plan.

Washdown, stacking and keeping the bag closed

Pads are not part of the washdown routine. A bag left open on a prep bench picks up room humidity within a day, the outer sheets cockle, and the first pad of the next shift wicks poorly. Keep opened bags in a lidded bin in the dry store and pull only the day’s count. Never stack a loaded crate on top of product sitting on a pad: the weight squeezes liquid sideways out of the pad and onto the floor, and the upper crate then drips onto the lower one.

Colour coding earns its keep in a mixed room. Blue for raw poultry, white for cooked or ready-to-eat product, and no pad at all in a crate headed straight for the fryer line. Pads should also leave the crate before the crate leaves the room; a pad that travels to the kitchen stuck to the base becomes a drip tray on someone else’s floor, and nobody will own it.

Building a pad specification across a poultry operation means matching grammage, size and swap interval to each room rather than buying one SKU for the whole site. The SAP absorbent pad formats at florpoly.com list the sheet sizes and loadings that suit crate-based thawing, and are worth reading before the next tender goes out.
