  • Patent number: 6254914
    Abstract: A method of recovering corn coarse fiber by flotation, which features the use of a hydrocyclone, or other separating machinery, in which the specific gravity of the slurry contained therein has been increased to approximately 12-14 Baumé so that the corn coarse fiber is of a lighter density than the remainder of the slurry. Therefore, the corn coarse fiber can be separated from the remainder of the slurry because it floats to the top of the slurry. If the present pericarp recovery process is added to a modified dry-grind ethanol production line, a high value co-product (the pericarp) is added to the other co-products and the end-product of ethanol, which can all be sold, and the economic efficiency of the plant is increased.

  • Patent number: 5942271
    Abstract: This invention describes a method for removing the skins of fruits and vegetables by explosive vaporization of the moisture in the fruit or vegetable under the skin. The fruit or vegetable is placed in a peeling vessel, and the pressure in the vessel is rapidly lowered, below atmospheric pressure, so as to cause explosive vaporization of the moisture. Some of the air in the peeling vessel may be removed prior to explosive vaporization, so that it can be carried out by mere condensation of water vapour present in the peeling chamber (without the aid of a vacuum pump or other vacuum device, for instance). In addition, the fruit or vegetable may be cooled prior to explosive vaporization, so that it can be carried out at a lower temperature than without such cooling, which is favorable to preserving the physical consistency and other qualities of some fruits and vegetables.

    Abstract: A finish topper for bulb crops having a plurality of longitudinal, parallel, generally horizontal, spaced-apart moving belts for conveying bulbs through the apparatus. Adjacent belts are driven at different linear speeds. In a preferred embodiment, alternate belts are replaced by stationary rails to maximize the speed differential. Below and adjustably close to the belts is a driven rotating blade for cutting the bulb stems and also exerting a downwards draft of air through the belts. Onions introduced onto the belts are conveyed through the apparatus by the belts, and the differential in speed between the moving belts and stationary rails causes the bulbs to rotate and gyrate randomly as they are being conveyed. Because the belts are spaced apart, the bulbs assume momentarily an attitude to permit the uncut stems of bulbs to extend downwardly between the belts. The bulbs are retained on their shoulders on the belts in inverted posture.

  • Patent number: 5705618
    Abstract: A process is described for extracting lignans from flaxseed which comprises contacting a substantially oil-free flaxseed meal with an aliphatic alcohol solvent, e.g. a mixture of methanol or ethanol with water, to extract lignans into the alcohol solvent and separating residual solids from the lignan-rich alcohol solvent. The lignan-rich alcohol solvent is concentrated by removing solvent therefrom and the lignan concentrate obtained is subjected to a base-catalyzed hydrolysis to liberate lignans therefrom in a non-complexed form. Thereafter, the hydrolyzed concentrate is subjected to either a liquid/liquid partition, e.g. by an ethyl acetate/water system, or anion exchange to further enrich the lignans and the lignan-enriched solution thus obtained is subjected to chromatographic separation to isolate lignans at a purity of greater than 90 percent. The lignan, secoisolariciresinol diglucoside, was found in amounts of up to 20 mg per gram of defatted flaxseed.

  • Patent number: 5616360
    Abstract: A method for processing melons provides greatly enhanced shelf life and maintains excellent quality of melon products so that they are suitable for human consumption. The harvested fresh melons are cooled to a temperature of approximately 36.degree. F. before they are graded and selected for further processing. The melons are then cut along their apexes to form melon halves. The seeds and soft tissue are removed from the melon halves, which are then cut to form melon segments. The finds are removed from the melon segments, which are then washed in a chilled chlorinated bath. The melon segments are then inspected and graded. Those melon segments that pass the inspection and grading process are then cut to form melon cubes that are washed in a chilled chlorinated water bath. The melon cubes are drained to remove chlorinated water, and the melon cubes are washed in a chilled citric acid and tribasic calcium phosphate bath.
