Definitions

  • the removal of the unit and ice-cream batch is performed by pulling a centrally arranged stem which is secured to the dashermember and bottom plate unit.
  • the above-mentioned disadvantages are overcome by forming the refrigerating can from the bottom towards the top thereof with a slight outward conicity. With a can so constructed it is found that a relatively moderate force is sufficient to remove the dasher member and plate unit carrying an ice-cream batch from the can.
  • compensation for wear may be obtained by lowering the bottom plate relative to the can.
  • the conical mantle l of the ice-cream machine has the bottom thereof closed by a bottom plate 2 that has a depending annular rim, said plate being provided with an axial bore through which passes the lower end of a hub 3 which drives an agitator dasher member 4.
  • the hub 3 is fitted to a coupling member 7 rotatably driven by a motor (not shown).
  • the hub 3 is also secured to a stem 5 provided with a handgrip knob 6, which permits the bottom plate 2 that is provided with a rim 201 and the dasher member 4 to be removed as a unit from the can 1. It will be observed that the rim 201 is supported within the machine by a bearing surface 101, as shown.
  • A is a generatrix of the wall of can I
  • B is a generatrix of a cylinder, whose diameter corresponds to the diameter of the bottom end of the can 1.
  • the can or conical mantle l is formed from the bottomtowards the top thereof with a slight outward conicity of the order of l to l5 mm per thousand millimetres height of the can, thus providing a difference between the minor and major diameters of thecan of about I mm.
  • the conicity may be between 2 and 4 mm per thousand millimetres height of the mantle and for a can whose height is about mm the conicity is of the order of about 3 mm per thousand. This extent of conicity as above described ensures that the dasher member and bottom plate unit, together with an ice-cream batch, can be readily and easily removed from the can without too great an effort.
  • a small capacity automatic ice-cream machine comprising a refrigerated conical mantle open at both ends and having an outward conicity from its bottom end toward its top end; bearing support means for the bottom end of said mantle, centrally apertured bottom plate means adapted to close the bottom end of said mantle, drive coupling means including a hub extending through said apertured plate means, means associated with said hub means arranged to support dasher means and means in axial alignment with said coupling means for lifting the dasher means and bottom plate means from the open end of said mantle.
  • bottom plate means includes a depending annular rim arranged to cooperate with the bearing support means.
