  • Patent number: 6105490
    Abstract: A vacuum meat marinating machine for products requiring a short vacuum massage cycle, comprising a substantially horizontal cylindrical vessel having a large opening at the top for rapid loading of product, said opening covered by a sealed vacuum cover during operation, and further having a hollow outer wall comprising a jacket for the circulation of liquid refrigerant. A paddle agitator is located within the vessel, having a hollow shaft running longitudinally within the vessel. Affixed at an angle to the shaft are a plurality of hollow triangular-shaped paddles, which paddles push product horizontally during operation. Liquid refrigerant circulates through the hollow wall of the vessel, as well as the hollow agitator shaft and paddles. The agitator shaft is connected to a reversible motor that periodically reverses the direction of rotation, thereby maximizing heat exchange between product and liquid refrigerant.

    Abstract: An aerated mixture of unflavored ice cream, yogurt or other food base mix is applied to one end of the interior of an elongated freezing chamber and is advanced along the chamber by a rotating screw or auger. As the mix is advanced within the chamber, it is cooled and worked to form a semi-solid product. Prior to discharge from the remote end of the chamber, flavor is injected and mixed into the product. The free volume in the system from chamber inlet to the discharge point is carefully limited to a minimum amount so that most of the product is cleared from the system during each individual serving. The result is the availability of individual servings of a fresh, high-quality frozen food product.

  • Patent number: 5383725
    Abstract: A closed, pressurized apparatus for introducing aggregate dust and rubber into a stream of liquid asphalt is provided. Aggregate dust and rubber are dispensed through a valve from a receiving chamber into a mixing housing. The aggregate dust and rubber enter the mixing housing at an intermediate location therein. The liquid asphalt is introduced into the mixing housing through a separate conduit at a location thereon above the point of entry of the aggregate dust and rubber. The liquid asphalt, the aggregate and the rubber combine within the mixing housing to form a slurry composition. A heating jacket substantially surrounds the mixing housing and a system for preventing liquid asphalt from backing up into the receiving chamber is also provided. The apparatus is particularly useful in an asphalt plant using a bag house.

  • Patent number: 5363747
    Abstract: Apparatus for preparing a product by the controlled metering of additive constituents into a base constituent includes a processing vessel having mixing and heating and/or cooling capability to produce a base constituent for discharge into the metering stage of a metering/mixing auger assembly. The metering stage of the auger assembly includes a screw type auger surrounded by a heating or cooling jacket and is operative to convey product from the processing vessel at a uniform rate to an auger mixing stage wherein the auger has increased pitch and is exposed to an open trough through which one or more additive constituents can be metered into the base constituent for mixing therewith. The auger mixing stage accommodates expansion of the mixed constituents. The metering/mixing auger and trough assembly may be readily disassembled for cleaning without need for tools.

  • Patent number: 5327818
    Abstract: The apparatus comprises a vat having a lateral wall and a bottom for pasteurizing, maturing and maintaining a product. A cover adjacent to the lateral wall and to the bottom controls the temperature of the product present in the vat. A first heat-exchange circuit is defined by the cover and by the vat. A heat-exchange fluid circulates in the first heat-exchange circuit. The first heat-exchange circuit includes a heat generator for the heating of the heat-exchange fluid and includes a first heat exchanger for the cooling of the heat-exchange fluid. A second heat-exchange circuit has a tank. A diathermic liquid circulates in the second heat-exchange circuit. A second heat-exchanger is disposed in the tank, and a refrigeration group is connected, in a heat-exchange relationship, to the second heat-exchanger. The second heat-exchange circuit is connected to the first heat-exchanger by a by-pass conduit parallel to the first heat-exchanger.

  • Patent number: 5302019
    Abstract: The invention provides an apparatus for mixing and kneading materials comprising a housing defining a mixing and kneading chamber, a jacket member enclosing the mixing and kneading chamber and a mixing and kneading member located in the interior of the mixing and kneading chamber. The mixing and kneading member is driven to a rotating and/or oscillating motion. For supporting the mixing and kneading operation, projection members are provided protruding from the jacket member into the interior of the mixing and kneading chamber. In order to simplify the design of the apparatus and, particularly, to improve the heating and cooling of the mixing and kneading chamber, at least some of the projection members are connected directly to the jacket member, or at least some of the projection members are integrally formed with the jacket member thus constituting a common jacket member/projection member unit.

  • Patent number: 5275484
    Abstract: An apparatus (10) with a central shaft (32) equipped with single or multiple-mixing elements (36) projecting perpendicularly from the shaft. Multiple processing zones (14-18) have adjustable openings (24) for introducing the product through adjacent processing zones for thermal treatment or conducting thermal reactions. A heating or cooling jackets (63 and 129) permits thermal control of the processing within the chamber. Additional thermal treatment can be achieved with micro-wave, infrared, hot gas or other available heating or cooling sources. The chamber is closed during vacuum or pressure processing by using rotary locks or double valving. A controlled dwell time in the chamber is accomplished with the adjustment of the opening of the weirs. The rotational velocity of the elements plays a major role in maintaining the material in the desired processing zone or causing advancement between adjacent zones.

  • Patent number: 5275485
    Abstract: A device for moving solid particles, especially one designed as cooling mixer, has a substantially horizontal jacketed tank (11), in which a shaft (14) is seated for rotation. The shaft (14) is equipped with mixing tools. Bulk material can be introduced into the tank (11) through a charging opening (23), and the processed material can be extracted from the tank (11) through a discharge opening (26). The product space of the tank (11) is equipped with partition walls which subdivide the product space into processing zones. The solid-particle mixer (10) is particularly well suited for quasi-continuous operation. Processing of the bulk material is carried out in the pile and product feeding toward the discharge opening (26) is effected in the state of a mechanically generated fluidized bed, or a product toroid.
