  • Filling cheese moulds with a curd portion
    Patent number: 3988090
    Abstract: An apparatus for filling cheese moulds with curd portions issuing from vertical sieve cylinders with a feed for a whey/curd mixture at their top, the cylinders cooperate with the upperside of a table having an aperture. Under the table a conveyor is advancing moulds each consisting of a sleeve with a separate bottom movable in vertical direction by means of a cam surface. At least a part of said cam surface is displaceable for altering the vertical travel of said supporting bottoms so as to change the length of the curd portions.
