  • Patent number: 8695905
    Abstract: An electrically-powered food processor apparatus with special features to aid in the processing of foodstuffs, particularly for Latin American recipes comprises a central hopper with a large open top. A top mounted central crank turns a blade disc located on the bottom inside surface of the hopper. The cutting design of the blade disc is such that the foodstuffs that are cut are the ideal size for use in recipes such as pasteles and alcapurrias. The blade disc can be interchangeable for other blade discs that allow for thinner foodstuffs, thicker foodstuffs, or special serrated designs.

  • Patent number: 8602337
    Abstract: A circulating processor includes a base, a container, a cutlery and a pressurizing mechanism. An operating motor is disposed in the base and is disposed with a mandrel therein. The container is disposed above the base, where a space is formed on its bottom part, and a reflux opening is formed on its upper half part and in communication with the space. The cutlery is positioned on the container's bottom part and connected to the mandrel. Thereby, when the operating motor operates, the mandrel and the cutlery are enabled to rotate synchronously, to mash food, vegetables and fruits in the container. The pressurizing mechanism is in communication with the space of the container. Through the pressurizing effect of the pressurizing mechanism, the mashed food, vegetables and fruits can be transferred into the container via the reflux opening, so as to perform circulating mashing treatment.

  • Patent number: 7798436
    Abstract: A portable chipper apparatus having a chipping disc with front and rear faces and a series of slots extending through the disc. A knife is arranged on the front face of the disc in proximate relation relative to each slot. At least two shredder/detanglers are secured to the rear face of the disc. Each shredder/detangler includes a base and at least three generally planar and substantially identical paddles arranged in spaced and generally parallel relation relative to each other. The paddles extend from the base at an angle and projects away from the rear face of the chipping disc. The paddles on each shredder/detangler have a continuous elongated linear cutting edge for impacting with and further reducing and cutting the size of the chipped material engaged by the paddles. Each shredder/detangler further includes an impeller at a distal end of the base.

  • Patent number: 7780102
    Abstract: The present disclosure relates to a wood chipper that has a feed roller driven by a hydraulic motor. Hydraulic fluid under pressure is provided to the motor through a two-stage pump, providing separate flows of fluid under pressure. The flows of the pump stages are combined for normal operation of the chipper. A bypass that will bypass the flow from one pump stage when the pressure of the fluid under pressure driving the motor exceeds a pre-selected level from increased load on the feed roller is provided. When the bypass is open the feed roller is slowed to reduce the feed rate of material into the chipper, and when the feed roller loads reduce, the flows will again be combined to speed up the feed roller.

  • Patent number: 7744025
    Abstract: An orifice plate with an outer grinding section and an inner grinding section is disclosed. The outer grinding section is the main grinding section leading to the main material collection stream, and an additional grinding section is present in the inner section of the orifice plate to remove useable material from material swept toward the center of the plate by the action of a rotating knife assembly on the plate. The useable material obtained at the inner section is also led to the main material collection stream.

  • Patent number: 7735762
    Abstract: A knife system of a disc chipper, the knife in said system being clamped to its operation position between a wear plate and a press block. The wear plate is supported to the knife disc adjustably for the inclination with respect to the surface of the knife disc. The adjustability is provided by means of a hinge and an adjustment strip. The hinge strip is located adjacent a knife and the adjustment strip is located at the next chip opening. A convergent space is provided for the adjustment strip. The adjustment strip is correspondingly wedge-shaped and has a position adjustable and locking means.

  • Publication number: 20100127107
    Abstract: A wood chipper includes a housing having an inlet opening and a discharge outlet with a chipper disk rotatably mounted in the housing and having a chipper knife mounted on a front face thereof adjacent a chipper slot extending through the disk. A plurality of fins are mounted on the back face of the chipper disk. An inlet hopper is connected to the inlet opening and a blow back shield is mounted in the upper end portion of the hopper with the shield including an outer layer of clear synthetic material extending across the hopper and an inner layer of synthetic material extending part way underneath the length of the layer of clear synthetic material. The inner layer may be provided with a safety warning thereon which is visible through the outer layer of clear synthetic material. A discharge chute is connected to the discharge outlet which has inwardly angled plates around part thereof. Vent holes are provided in a wall of the housing which add air flow to the wood chipper when it is being operated.

  • Patent number: 7721981
    Abstract: A mechanical control mechanism for the feed of a brush chipper is disclosed. The feed control bar has four positions: (1) forward or feed, (2) neutral, (3) reverse, and (4) stop. The hydraulic control valve has the three usual positions: (1) forward or feed, (2) neutral, (3) reverse. A function of the feed control bar is to provide the three function of the hydraulic control valve, plus the fourth in a fashion amenable to emergency situations. To these ends, the control bar has an extreme rearward position wherein the feed mechanism is stopped. The only permissible change to the stopped condition of the feed mechanism is to reverse the feed. Until a reset lever is manipulated, the hydraulic control valve cannot be put into a forward feed position.

  • Patent number: 7690592
    Abstract: The invention provides an interlock system whereby operation of a domestic appliance such as a food processor containing an electric motor capable of driving a bladed or similar processing tool at relatively high speed is inhibited unless a vessel having a first or a second base configuration is securely mounted to the appliance so as to contain the tool; the vessel having a lid or cover intended to be in place for safe operation when the processing tool is driven by the motor. A vessel-supporting surface of the appliance carries several up-standing latches, each of which is formed with features capable of co-operating with vessels having either of the base configurations to temporarily latch either type of vessel operationally to the appliance.
