A rotary disk displaces longitudinally in a reciprocating and revolving manner along the threads of a screw rod so that the whip passes through holes in the rotary disk. Blades on the rotary disk rotate clockwisely and counter-clockwisely to generate a water current which speeds up the mixing of the dairy product and the water in a consistent manner to form a finer whip.

  • Patent number: 5906436
    Abstract: A composting system for promoting maximum aerobic microbial activity in a composting bed. The system includes at least one composting bay for receiving composting material and an agitator for aerating and displacing composting material as it travels through the composting bay. The agitator has at least one structural frame member, and a conveyor, a feeder, and at least one bridge breaker that are mounted to the structural frame member. As the agitator travels through the bay, the feeder takes composting material from the bay and feeds it to the conveyor which discharges the composting material rearwardly into the bay behind the agitator. The bridge breaker displaces the composting material above the feeder causing the material to fall substantially evenly onto the feeder, thereby preventing large amounts of composting material from suddenly collapsing onto the feeder which can result in overload conditions on the feeder drive system.

  • Patent number: 5829875
    Abstract: The present invention provides an apparatus for first separating and later mixing a of materials stored in a cylindrical container. The apparatus of the present invention serves as an effective barrier during storage of the materials. It also serves as an apparatus for thoroughly mixing the materials when they are ready to be used.The apparatus of the present invention consists of: a mixing member formed with one or more mixing spokes for stirring the materials; a sealing member that releasably attaches to the mixing member and together with the mixing member forms a barrier when the two are joined, but separated from the mixing member allows for the combining of the materials within the container; and a mixing rod that attaches to the mixing member and is long enough to protrude from the container to allow the user to manipulate the mixing member. The apparatus of the present invention is formed so it is difficult for the mixing member and the sealing to reattach once they have separated.
