<p>PCT No. PCT/FR87/00496 Sec. 371 Date Aug. 10, 1988 Sec. 102(e) Date Aug. 10, 1988 PCT Filed Dec. 11, 1987 PCT Pub. No. WO88/04141 PCT Pub. Date Jun. 16, 1988.The object of the present invention is the treatment of a curd (5) obtained from milk (1) which had been subjected to a pretreatment aimed at coagulating the milk casein and precipitating the whey protein through a microfiltration loop (30) comprising at least one cartridge (34) with ceramic tubes (36), so as to separate the cheese from the whey. The device comprises a means for a sequential unclogging under high pressure (39, 43, 44) by reverse permeation for a short period of time without interrupting the continuous microfiltration. Advantages: increased useful life, no clogging, cleaning and sterilization with all the acid and alkaline products used in a dairy plant, insensitiveness to pH, preservation of the quality of the product, low pressure drop across the membrane, high yield.</p> |
