Abstract: A system for cooling cooked product by means of a shower achieves particularly efficient cooling through intermittent operation of the shower and is provided with a showering cabinet having separation of contaminated and uncontamined shower coolant. The floor of the cabinet is provided with a perforated upper surface which has imperforate troughs for receiving the wheels of a product-containing rack. In addition, at least one walkway extends along the floor and is adapted to be covered entirely by a removeable, vaulted walkway cover. Coolant passing through the perforated upper surface is accumulated and recirculated for use by the shower. However, contaminated coolant which accumulates in the troughs, is routed to a drain for disposal. The vaulted cover shields the contaminated walkway, prevents coolant from being contaminated by the walkway and directs the coolant to the perforated upper surface for recirculation.
