  • Patent number: 4994287
    Abstract: The invention concerns a method and apparatus for filling curd into cheese moulds (6). During the cheese production process, milk is separated in a cheese vat (1) into curd and whey (2), both of which are routed to a piping manifold that distributes the curd for the run-off drainage of the whey (8) into cheese moulds (6) placed in a whey drainage vat (7). According to the invention, the manifold comprises a main line (3) exiting from the cheese vat, a plurality of side lines (5) branching from the main line and discharging into the multiple cheese moulds (6), and a return line (9) which forms a continuation of the main line and is routed back to the cheese vat, whereby the discharge of the curd in whey takes place as a continuous process via the main line and the side lines into the cheese moulds, while simultaneously the excess flow is returned at a set rate via the return line back to the pan.

  • Patent number: 4612853
    Abstract: A cheese kettle (1) is used for the separation of whey from the cheese mix and the comminuting of the cheese mix into curd particles takes place. The cheese kettle (1) is composed of two side-by-side, substantially cylindrical parts (3), located so that they partly interpenetrate, and each provided with rotary tools (2) treating the cheese mix. It is essential that the cylindrical parts (3) of the kettle (1) are inclined towards each other so that their interpenetration increases in the upward direction. The kettle bottom (7), includes circular segments substantially at right angles to the axes (4) of the cylindrical parts (3), and slope towards the draining aperture (10) in the center of the bottom, whereby the kettle is emptied without any need to tilt it specifically, and the tools (2) in the kettle can be so shaped that their sides follow, during rotation, the bottom and sides of the kettle, whereby the cheese mix is given a complete mixing and comminuting treatment covering all parts of the kettle.
