Abstract: 1,041,409. Cheese making. PAASCH & SILKEBORG MASKINFABRIKKER A/S. Dec. 10, 1963 [Dec. 15, 1962], No. 48671/63. Heading A2B. In cheese making, milk prepared for coagulation is passed into a moving mould, at one end thereof, to assume the form of a wide layer of a depth corresponding to the thickness of the curd particles on coagulation, and at the other end of the mould allowing the curds and whey to fall from the mould, such fall being assisted if desired by supplying whey from a previous run, in readiness for the operation of curd and whey separation. Instead of forming a wide continuous layer of prepared milk, the coagulating mould preferably comprises a large number of closely spaced moulds to form a discontinuous layer. As shown in Fig. 4, treated milk is distributed by perforated pipe 21 in a thin layer across the width of conveyer band 8. The band 8 has zig-zag partition strips (Fig. 2) running across its width. The enclosed cells so formed receive the treated milk which coagulates into curd. As the band passes over tensioning roller 11, the strips separate and the curd falls out on to conveyer 23. The curd may be positively ejected by providing each cell with a piston 34, Fig. 7, the piston being raised by a cam surface 36 actuating piston rods 35. In a modification, Figs. 8 and 9, treated milk is distributed by pipe 54 on to a slowly rotating disc comprising an open frame defined by radial arms 43 and periphery 44 forming sectors filled by open cellular plates 46, sealed across the bottom by hinged plates 47. The treated milk fed into the cellular structure coagulates whilst the disc rotates until each sector reaches a point where the hinged bottom plate, which is normally maintained horizontally by its depending arm 51 bearing on cam 51, is allowed to drop as shown on the left, so that the curd falls out on to conveyer 57. Ejection of the curd may be assisted by spraying with whey from a second distributer pipe 55.
