Abstract
Abstract An apparatus for the continuous matting and milling of cheese curd. The apparatus includes a housing which houses an upper, water-permeable, endless conveyor belt and a lower endless conveyor belt which operates in the opposite direction to that of the first belt. A mixture of cheese curd and whey is deposited as a layer on the upper belt and the whey is drained through the belt and is discharged through the lower end of the housing. The matted curd is transferred from the upper belt to the lower belt and as a result is inverted, and is subsequently discharged to a curd milling unit which acts to cut the mat of curd into cube-like chunks.
