  • Patent number: 4142460
    Abstract: A method and an apparatus is described for preparing a crunchy food topping of random sized pieces or granules of cooked dough in which the dough is mixed, subdivided to random sized pieces or granules, baked, allowed to cool, sized and packed. The granules can then be applied to a food product, e.g., a dessert such as pie, cake, pudding, etc., by hand. The random sized pieces or granules are prepared within a dough-containing trough or hopper having a rotating cutting or comminuting device, e.g., wires near its bottom end. These wires are supported upon spokes which are mounted rigidly upon a rotating drive axle near the bottom of the hopper. The hopper has an outlet at the bottom through which the granules exit to a conveyor used for transporting them to a baking oven.

  • Patent number: 4128074
    Abstract: Chopped food such as ground beef or ground pork or sauce is cooked and maintained at an elevated temperature. An agitator is provided to stir up and dispense solid food pieces uniformly in the liquid phase. A pump connected to the agitator expells the uniform dispersion at a constant rate to a vibrating tray feeder. The feeder advances the food product as a fluid sheet which is allowed to fall from the edge of the feeder as a uniform continuously descending curtain onto the food base. Material that falls beyond the edges of the food base is recycled.

  • Patent number: 4093073
    Abstract: A dough package is described that comprises a fiber can containing dough in which the can wall is composed of a body layer of kraft paper having a helically disposed butt joint defined by its mating side edges to which is releasably bonded a relatively thin lightweight label. The label is releasably bonded to the underlying kraft paper by means of a peelable adhesive layer which functions in one of two ways. In the first, the adhesive functions as a releasable layer interposed between the body layer and the unexposed surface of the label. This layer is released from the label and remains in place when the label is peeled back. In the second method the peelable adhesive layer ruptures or splits as the label is lifted although a small fraction e.g. 10% of the surface kraft fibers may be pulled out when the label is removed. The term "peelable adhesive" herein refers both to adhesives that split and those that separate from the label when the label is lifted.

  • Patent number: 4084013
    Abstract: A continuous process is described for forming simulated nut-like food products by providing a mixing vessel or a plurality of vessels which include mixing zone portions distributed along the flow path of the material being prepared with one or more fluid inlets between the portions of the mixer. An edible hydratable film former and a fat in liquid form are introduced and mixed continuously in one portion of the mixer. Water is introduced continuously through the inlet at a point intermediate the ends of the mixer and the mixture thus formed is continuously agitated to produce an aqueous dispersion in which the film forming substance is hydrated by the added water to form a stable dispersion which is then molded or otherwise formed and dried to a moisture content of 10% or less.

  • Patent number: 4006025
    Abstract: Colloidally stable dispersions of a spectral sensitizing dye are formed directly in water without the use of an organic solvent. The process of the invention involves mixing the dye particles with water to form a slurry and then homogenizing or milling the slurry at an elevated temperature in the presence of a surfactant to form finely divided particles uniformly dispersed in the water.

  • Patent number: 3958016
    Abstract: Disclosed herein is a method for processing wheat in an aqueous medium to separate the endosperm from the husk wherein the starch granules of the endosperm are maintained in an intact, ungelatinized form and the gluten protein of the endosperm is maintained in a dispersible and substantially undenatured state. The aqueous medium is innoculated with a harmless micro-organism which selectively grows in each of the processing steps and thereby excludes the growth of pathogenic organisms in the system. The endosperm obtained from this process can be used as a baking ingredient after concentration or drying or it can be separated into its starch and gluten components.
