ABSTRACT:
A method is provided, along with apparatus for practice of the method, wherein laundry, such as linen or the like, is treated, following a washing operation applied thereto, by applying centrifugal force to extract rinsing liquid from a saturated laundry batch and then applying to the exterior of the laundry batch a pressurized fluid flow as a further treatment step, which is withdrawn from the laundry work batch from a point generally within the batch whereby rinsing liquid is withdrawn in a direction countercurrent to the preceding centrifugal extraction step. A suction may be applied at a point within the batch to either establish or enhance the liquid extraction operation.
The apparatus of the invention includes a perforated spin-drying drum within a housing such that a circumjacent space is defined between the drum and the housing, and a remotely located blower in conduit communication with the housing generates a pressurized flow to the circumjacent space. The same blower may also be utilized to create a suction or negative pressure area within the drum, and the conduit from the blower, which is utilized to establish the suction in the drum, may also serve as a means of transporting laundry from the drum to other stations of the laundry treating system for subsequent treating steps.
