Abstract (en)

[origin: US2002116770A1] Laundry items washed and, if necessary, aftertreated in the tunnel washing machine (10) are, upon leaving the tunnel washing machine (10), freed from a portion of the liquid clinging to them (bound liquor) in a hydroextraction press (21). The remaining portion of the bound liquor is removed from the laundry items by subsequent drying, a process which consumes much time and energy. The invention proposes to treat the laundry items in a last treatment zone of the tunnel washing machine (10) with a liquid which has a higher temperature than the liquid of the preceding treatment zone. As a result, the liquid of the bound liquor has a higher temperature. This makes it possible to remove a greater portion of the bound liquor from the laundry items in the hydroextraction press (21), so that the laundry items leaving the hydroextraction press (21) have only a slight residual moisture which still has to be removed by drying. This shortens the drying process and above all requires less energy.
