A six-bay serve-over counter moving 60 to 80 kg of display meat a day will give up roughly 1.5 to 3 litres of purge before the lunch trade is finished. On a flat steel tray that liquid pools under the product, climbs the cut edges by capillary action and dulls the bloom by mid-afternoon. A thawing pad changes the geometry of the problem: exudate is pulled down into a gel layer and held there until the pad is swapped. Here is how one mid-sized butcher shop runs pads across a ten-hour trading day, from the 06:30 setup to the 17:00 close.
The mistake we see most often on butcher counters is buying pads by product weight. A 400 × 600 mm stainless display tray with a 25 mm lip takes a 380 × 580 mm pad; anything smaller leaves a 30 mm bare channel around the edge where purge collects and eventually spills over the lip onto the counter. The shop in this example standardised on three sizes: 200 × 300 mm for offal and trim trays, 300 × 400 mm for the chicken and mince bays, and 400 × 600 mm for the two beef display trays. Grammage matters as much as footprint. At 0.8 to 1.2 L/m² of retained exudate, a 400 × 600 mm pad holds between 190 and 290 mL, which covers a 20 kg tray of whole-muscle beef at 1 to 2 percent purge but not a tray of pork shoulder at 3 to 4 percent.
Two practical rules sit above all of this. First, the pad has to carry a food-contact declaration for the film side that touches product; a pad sold for under-tray drip in transport is not automatically the same article. Second, the tray goes into the chiller at 0 to 4 °C, and the pad does not change that requirement. It manages liquid. It does not cool anything.
Counter staff are not going to run tests mid-queue, so the checks have to be visual and fast.
In practice this shop swaps the chicken and mince bays at 11:00 and 14:30, and the beef trays once at 13:00. Four hours is a sensible default interval for a busy counter; the pork tray, with its higher drip, sometimes needs a third change on a warm Saturday.
The most useful number in the whole routine comes at 17:00. Weigh a used pad against a dry one from the same pack. A 400 × 600 mm pad that started at 42 g and comes back at 240 g has taken on roughly 200 mL, which is a little over 1 percent of the 18 kg of beef it sat under. Log that figure for a fortnight and the pattern becomes obvious: Tuesday and Friday are heavier, the pork bay always runs hottest, and the 60 g/m² pad is undersized for the shoulder tray. That is the evidence you need to move up a grammage rather than guess.
Used pads go straight into general waste, not the drain, and never back into a clean tray. Two bays, one bin liner, end of shift.
If you are specifying pads for a counter rather than just buying what the wholesaler stocks, start with the pad range at florpoly.com SAP absorbent pads and match grammage to the drip load you have actually measured, not the one on the label.
