  • Publication number: 20100068027
    Abstract: An automated build-by-layer rainbow pallet system comprises a layer build track and a layer build cart that carries a layer build robot and a number of positions for building rainbow pallets, for storing emptied supply pallets, and for storing empty half-pallets. On the rail-sides are dozens or hundreds of supply pallet conveyors for pallets of products to be picked-from when building the rainbow pallets. These are placed on one or both sides of the layer build track. The layer build robot can position itself in front of the appropriate supply pallet conveyor for picking. Once in position, half or full layers can be picked from the supply pallets and positioned over the target rainbow pallet to be built. The process of picking and building layers as the layer build cart repositions in front of the appropriate supply pallet conveyor is repeated until all of the on-board rainbow pallets have been built.

  • Publication number: 20080241343
    Abstract: A food making process comprises starting with Lupin legumes with minimum levels of alkaloids, dehulling the Lupin legumes to produce split seed kernels, mixing the split seed kernels with hot water to hydrate them into a slurry, grinding the slurry to blend and smooth it into a product base, cooking the product base to achieve a particular flavor and aroma consistent with a target food product, cooling the product base to stop cooking, and further processing the product base into a target food product like soups and beverages. In particular, the Lupinus Angustifolius variety produces the best results, but other sweet lupin varieties can be used if they have been leached of their bitter tasting alkaloids. The products produced have high levels of protein, vitamins, and other nutritional values. Both batch and continuous processes are possible.

  • Patent number: 6652213
    Abstract: An automated warehouse system for a building has elevators for automatically accepting incoming material on pallets. A rotating forklift mounted inside the elevator extends its forks to reach out and bring in the pallets. Once inside, the rotating forklift spins around to face inside warehouse doors. When the elevator car arrives at a designated level, the rotating forklift deposits the material on the pallet on a temporary shelf just outside the elevator. Each level has an aisle cart that moves along an aisleway for both a loading elevator and an unloading elevator. Each aisleway is intersected by several row rails that are right angles to the aisleway. The aisle cart carries a battery powered row cart that can run back and forth along the rows. The aisle cart is positioned at the appropriate row along the aisleway, and the row cart carries, deposits, and picks up material on pallets. Storage positions are provided along each row, front to rear.

  • Patent number: 5498702
    Abstract: A process for manufacturing a treated polyuronic acid. The process involves heating an aqueous dispersion of a polyuronic acid, such as a pectin, at a temperature above about 100.degree. C. for an amount of time sufficient to obtain a hydrolyzed, or treated, polyuronic acid mixture which separates upon standing and cooling into a clear solution, which is the hydrolyzed polyuronic acid phase, and a precipitate. The hydrolyzed polyuronic acid phase includes at least 25% of the polyuronic acid substance polymers having a degree of polymerization (DP) in the range of about DP1 to about DP20. The hydrolyzed polyuronic acid, or the treated polyuronic acid, then is recovered for use in a food product.

  • Patent number: 4873112
    Abstract: A fruit concentrate sweetener and process of manufacture are disclosed wherein the sweetener is formed from a hydrolyzed starch having a dextrose equivalent of about 5 to 25 and a clear fruit concentrate of at least about 40% soluble solids and about 0% insoluble solids to have about 40 to 65% complex carbohydrates, about 35 to 55% simple sugars from the fruit origin and about 0 to 5% nutritional components. The sweetener may be partially or substantially completely deflavorized and may be dried up to about 96 to 99% soluble solids. Further preferred steps of the process facilitate both deflavorization and drying while also yielding a sweetness level generally similar to sucrose with only about 50% simple sugars, the remainder being nutritionally desirable complex carbohydrates. The sweetener may be included in a variety of sweetened food and beverage products.

  • Patent number: 4564525
    Abstract: Confections produced from flavor powders obtained from powdered roasted syrup of dahlia tubers. These dahlia flavored powders can be used to replace cocoa powder. When milled with a confectioner fat, the dahlia flavored powders produce a confection similar to chocolate. The powders can also be blended with protein, milk solids, fiber, carbohydrates such as starches, bland flours and sugars to produce flavor mixes which may be used as a direct replacement for cocoa powder and which can be ground with cocoa butter or a confection fat to produce chocolate-like confections. Foods incorporating these confections such as beverages, baked goods, desserts, icings, coatings, candies, syrups or ice cream are similar to analogous products made with natural cocoa or chocolate.

  • Patent number: 4285735
    Abstract: A process for making a fructose polymer mixture containing chiefly inulin and inulides with minor amounts of impurities is based on the finding that inulin is in a soluble metastable state at room temperature as it exists in the dahlia tuber. Novel steps in the process are the separation, without the use of heat or adding water, of the water soluble from the ground dahlia tuber within about 10 minutes after grinding, followed by separation by coagulation of protein color and flavor bodies by heating at the boiling temperature from 3 to 10 minutes. No chemical defecating agent, such as lime water is used or required. The resulting clear extract is concentrated to 40% to 70% solids. Dry product is recovered by crystallizing the concentrated extract at 1.degree. to 15.degree. C. The product differs from inulin in that the product, in addition to inulin, also contains inulides, protein, color, flavor bodies, and minerals.
