  • Patent number: 4634362
    Abstract: A device for manufacturing annular shaped products is achieved by forming a recess which extends about a plate-shaped part of a slide which is connected with the surrounding part of the slide with the aid of a few connecting ribs. The thickness of the plate-shaped part is at least substantially equal to the thickness of the slide part surrounding the recess and the height of the connecting ribs is less than said thickness. The undersides of the ribs are at a level above that of the underside of the slide part surrounding the recess. An expelling member is provided with hanging limbs separated from one another by slots in a manner such that the hanging limbs fit in the holes between the connecting ribs. The connecting ribs can fit in the slots.

  • Patent number: 4497244
    Abstract: The invention relates to a device for covering foodstuff with granular and/or powdery material comprising a frame, a bunker supported by said frame receiving a supply of granular and/or powdery material and means for displacing the foodstuff along a path extending below an outlet port of the bunker, whereby below the outlet port a sieve plate having a plurality of apertures is arranged and the device comprises means for displacing the material flowing out of the bunker in a direction opposite the direction of displacement of the foodstuff during operation.

  • Patent number: 4298327
    Abstract: A frame comprising crossplates 8 and 13 coupled and spaced apart by coupling rods 10 (FIG. 2) faces, by the crossplates 8 and 13, opposite ends of aligned plunger pairs 7 and 16, there being a plurality of said pairs associated with respective openings, in which they are a close sliding fit, in a housing in which is a supply chamber 2 surmounted by a supply hopper 6. Reciprocation of the frame 8, 10, 13 causes movement of the plungers 7, 16 with there being a movement time lag between the plungers of the pair to provide, when within the supply chamber 2, a space between the confronting ends of said plungers 7, 16, for receiving material from the chamber 2 as an object 18 which can be ejected (e.g. by wire 21) when the said ends are outside the housing 1. This arrangement ensures consistency of shape of the product and of the location at which it engages from the device, facilitating subsequent treatment and/or handling thereof.

  • Patent number: 4254534
    Abstract: Apparatus for use in the manufacture of disc-like products from semi-solid foodstuffs comprises a hopper, a compression chamber (8) communicating with the hopper, a pusher (21) slidable along an associated side wall (2) within the hopper for advancing foodstuff from the hopper into the compression chamber (8), and a plate (19) having at least one aperture (18) for receiving foodstuff from the compression chamber (8) and for forming said foodstuff into disc-like products, the side wall (2) of the hopper being inclined relative to the plate (19) and lying in the same plane as a side wall (7) of the compression chamber.

  • Patent number: 4207654
    Abstract: There is provided a device for preparing coherent materials from deformable foodstuffs, for example, ground meat. Said device comprising a foodstuff bunker and an apertured plate to form the coherent products in the apertures, said bunker culminating at least one pushing member for pushing the foodstuff out of the bunker.
