  • Patent number: 7815741
    Abstract: A reactor for hydrolytic splitting of cellulose under high pressure and heat has an inlet and outlet each with a cross-sectional area smaller than the cross-sectional area of the reactor. The pressure and heat in the reactor forms a cellulose plug within the inlet and the outlet. The inlet plug stops cellulose from escaping out the inlet. Cellulose begins to breakdown under heat, pressure, and if required an acid or a lubricant. The outlet plug slows downstream movement of cooking cellulose. Cellulose may be pre-treated by the addition of water, a weak acid, a lubricant, or a combination of the foregoing. The outer surface of the plug cooks faster than the inner core of the plug, becomes a liquefied slurry, and slides faster towards the outlet than the inner core.

  • Patent number: 7815876
    Abstract: The reactor pump for hydrolytic splitting of cellulose is configured to pump cellulose, under high pressure, with low availability of sugar into a reactor. The reactor has an upstream transition segment connected to a downstream reaction chamber. The transition segment has an inlet that is smaller than the outlet. The inner walls taper outward. The chamber has an inlet that is larger than the discharge outlet. The inner walls taper inward. The transition segment outlet has an area that is substantially the same as the area of the chamber inlet. Back pressure in the chamber forms a cellulose plug within the inlet of the transition segment. The plug stops cellulose from escaping out the inlet. High pressure pumping forms a cellulose plug within the discharge outlet of the chamber. The plug slows downstream movement of the cooking cellulose giving the cellulose time to cook. Cooking cellulose begins to breakdown under heat and the injection of acid, if required.

  • Patent number: 5034421
    Abstract: A spun product from a combination of a saccharide and a hydrophobic ingredient is hydrophilic with low concentrations of such ingredient but becomes increasingly hydrophobic as the concentration of the hydrophobic ingredient is increased, although the end product nevertheless acts hydrophilically when the water temperature is elevated. Larger ratios of hydrophobic substance-to-saccharide yields a spun fibrous product that has increased stability. Similar stabilization can be attained by adding either beeswax or a petrolatum to the saccharide either in the presence of or absence of a separate active ingredient. Examples are given for masking the taste of unpalatable medicaments or other ingestible substances. Delayed release burn or wound dressings are also described. Control with beeswax can also provide a time release tablet or the like when swallowed.

  • Patent number: 4416701
    Abstract: The method for the production of starch from grain or ground grain products by the wet process comprises a brief steeping of the raw material during which the morphological structures are not broken down by chemical or microbiological processes, and of a comminution of the steeped raw material in a high-pressure apparatus equipped with a splitter head. In this high-pressure apparatus, the steeped raw material is subjected to a pressure of at least 10 bar, fragmented under the action of high shear forces, and exposed to the atmosphere, thus causing the necessary structural breakdown between the starch grains and the protein. For shelled corn after the addition of process water, the shelled corn is fed to a heated pressure steeping apparatus. After a maximum of three hours at a pressure of 10 to 15 bar, the necessary moisture absorption is achieved. Excess water is fed to an evaporator. A pressure reducing apparatus at the output of the steeping apparatus produces a preliminary fragmentation of the corn grains.
