    Abstract: A method and system are provided for pasteurizing a fluid product. Heated fluid product flows through a passageway to a directional flow valve for directing the heated fluid product through either a primary flow path or a divert flow path. A temperature sensor senses temperature of the heated fluid product at a location in the passageway spaced from the valve so that change in temperature of a portion of the heated fluid product is sensed before that portion of the heated fluid product flows to the valve. The valve directs flow of the heated fluid product from the passageway to the divert flow path when the sensed temperature is below a predetermined temperature for pasteurization of the fluid product, and continues to direct the flow to the diverting flow path at least until the sensed temperature is at or above the predetermined temperature for a predetermined period of time.

    Abstract: Heat is applied to a solid or semi-solid material in a cylindrical container in such a way that a precise, predetermined amount of heat is transferred to a horizontal layer of the material until it softens sufficiently to allow the heating element to sink into the material where it will heat the next layer. The container is rotated about a vertical axis, and a horizontally-oriented heating element is lowered into contact with the material to apply heat to a horizontal layer. The heating element is lowered through the material in a controlled manner to heat progressively lower layers within the container, until the whole container has been heated. The heating element may be heated by pumping hot water therethrough, or by other means. A container of hot liquid may be cooled in a similar fashion, by gradually raising a cooling element from the bottom of the container.

  • Patent number: 5288471
    Abstract: The method includes the steps of: preheating a selected volume of product to a temperature proximate to the maximum temperature of the treatment; irradiating the product with an alternating electromagnetic field in order to heat the product to approximately 50.degree. C.; maintaining the product at a substantially constant temperature for a set time; cooling the product to a temperature close to the packaging temperature. An apparatus for performing the above method includes a pair of facing emitting surfaces connected to the terminals of an oscillator operating below 1 GHz and set to heat the product to a maximum temperature of approximately 50.degree. C. The apparatus also includes a thermally insulated region to maintain the product at the maximum temperature of the treatment for a selected time adapted to ensure the complete destruction of the bacterial and sporal loads.

  • Patent number: 5228394
    Abstract: A pressure processing method and processing apparatus for sterilization, denaturation, etc. of food materials include a free piston fitted in a pressure container so that the free piston is slidable in an axial direction of the container, the pressure container being partitioned by the free piston into two chambers to prevent mixing and contact between a material to be processed and a pressure medium. The material to be processed filled in and supplied to one chamber is pressure-processed by the sliding movement of the piston caused by supplying the pressure medium to the other chamber. Three or more pressure containers, in each of which is fitted a free piston, are provided, and a series of processing operations including pressurizing and holding, discharge and supply of the material to be processed are carried out in a batch continuous manner in the same time zone.

  • Patent number: 5228396
    Abstract: An incubator apparatus (10) for preparing an aerobically cultured plant material, such as a soyfood substrate (11), inoculated with a beneficial microorganism to form a cultured food, such as Tempeh, is described. The incubator apparatus is comprised of a water tray (13), which provides a water bath (15) for heating the inoculated soyfood substrate loaded in shallow metal trays (45), preferably stainless steel trays. The trays are then supported on tray racks (43) that are mounted in the water bath so that the trays are partially immersed in the water bath. The trays holding the inoculated soyfood substrate are then sealed in the water bath by a cover (61). The cover mounts over the tray racks and is partially immersed in the water bath to seal the cover over and around the trays filled with the inoculated soyfood substrate.

  • Patent number: 5226353
    Abstract: A machine for automatically shaving a large bar of chocolate for forming a thin chocolate shaving that curls into a spiral, for use for decorative purposes. The machine has cutters that will cut an end of a chocolate bar in three separate spirals, on each stroke of the cutter. The chocolate bar is moved a desired distance for new cuts. The knives are partly curved in cross section and have cutting edges that are angled to insure a smooth separation of a thin shaving to form the curl around the curvature of the individual knife. The chocolate temperature is important in cutting, and generally is maintained in the range of 88 to 90 degrees Fahrenheit. The machine itself can be placed in a suitable environment or chamber to maintain that temperature.
