ABSTRACT:
An ice cream preparation apparatus having a cold storage container with a hole through its bottom in which a supporting member is disposed. A rotating screw in the hole through the supporting member moves material through that hole and out the bottom of the container. A covering plate is selectively openable and closable over the hole. A first rotatable blade is inclined downwardly along the inner surface of the cold storage container moves material off the wall. A second blade rotates around the bottom of the container. A second screw type rotary member extends along the radial direction parallel to the second blade and is rotated for moving material toward the supporting member. A third blade is upstanding in the container.
