  • 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: 7794548
    Abstract: A process for preparing a starch-containing biomass particle stream having a significant percentage of fiber for processing into ethanol comprises the first step of: mixing the particle stream with a liquid solvent to dissolve at least a portion of the starch in the carbohydrate particle stream to form a carbohydrate slurry stream containing starch dissolved in the liquid solvent. This first step removes a portion of the fiber from the carbohydrate slurry stream. In a second step, the carbohydrate slurry stream is held in a settling tank to remove a further portion of the fiber. An enhancement to the process is suitable for use with shell corn or other biomass having an oil-containing germ portion and a non-germ portion comprising mainly carbohydrates and fiber. This enhancement includes the step of grinding the corn to particles of a size suitable for separating the germ particles from the non-germ particles. The germ particles are processed first to remove the oil and then to remove the carbohydrates.

    Abstract: A stable and non-separable composition comprised of starch and a water-immiscible material can be prepared in the absence of external emulsifying or dispersing agents by thoroughly solubilizing an aqueous dispersion of the starch at elevated temperatures and incorporating the water-immiscible material into the non-retrograded starch under conditions of high turbulence. The resulting dispersions form soft gels that can be easily converted to pourable fluids by the application of heat. Upon drying, these dispersions yield solid compositions that are easily redispersed in water to form smooth, stable dispersions. These compositions are useful as thickening agents, suspending agents, waterproof coating materials, adhesives, fat substitutes, and seed coatings. They are receptive to the addition of a variety of other water-immiscible materials, such as volatile and essential oils, food flavorants, medicinals, waxes, agricultural chemicals, and the like.

    Abstract: Chemically modified RS.sub.4 starches are provided which have a high degree of resistance to .alpha.-amylase digestion and can serve as low calorie food additives in products such as breads or crackers as a source of dietary fiber. The starches of the invention can be prepared from any type of starting starch (e.g., wheat, corn, oat, rice, tapioca, mung bean, potato or high amylose starches) and are preferably formed as phosphorylated distarch phosphodiesters. The preferred phosphorylating agent is a mixture of sodium trimetaphosphate (STMP) and sodium tripolyphosphate (STPP) in the presence of sodium chloride or sulfate. The starches are advantageously prepared in an aqueous slurry reaction at basic pH and moderate heating.

  • Patent number: 5720822
    Abstract: Thermally-inhibited, pregelatinized non-granular starches and flours are prepared by pregelatinizing the starch or flour and thermally inhibiting the starch or flour by dehydrating the starch or flour to anhydrous or substantially anhydrous and then heat treating the dehydrated starch. The pregelatinization may be carried out prior to or after the thermal inhibition using known methods which disrupt the granular structure such by drum drying or jet cooking and spray-drying. Preferably the starch or flour is adjusted to a pH above 7.0 prior to the thermal inhibition. The starch may be dehydrated by heating the starch in a suitable heating apparatus, by extracting the water from the starch using a solvent such as ethanol, or by freeze drying the starch. Preferably the starch or flour is treated with a solvent to remove proteins and/or lipids and thus prevent off flavors.

  • Patent number: 5718770
    Abstract: Pregelatinized granular starches and flours are thermally inhibited by dehydrating a starch to anhydrous or substantially anhydrous and then heat treating the dehydrated starch at a temperature and for a time sufficient to inhibit the starch. The starch may be pregelatinized prior to or after the thermal inhibition using methods known in the art which retain the granular integrity. Preferably, the pH of the starch or flour is raised to 7.0 or above prior to the thermal inhibition steps. The dehydration step may be carried out by directly heating the starch, by extracting the starch with a solvent, or by freeze drying the starch. Preferably protein and/or lipids are removed prior to or after the thermal inhibition.

  • Patent number: 5674322
    Abstract: In the process, a starch-containing suspension 1 is divided at admixture of washing liquid 5 in a centrifuge "A" into starch-containing concentrate 2, a first liquid phase 3 with primarily dissolved substances and a second liquid phase 4 with primarily undissolved substances. The first liquid phase 3 is especially suitable as washing liquid in counterflow washing processes as it contains no obstructive undissolved substances. Also, the disposal of this liquid phase is simpler. The second liquid phase 4 with the undissolved substances is generated in higher concentration compared to conventional processes so that the processing of this phase is less cumbersome.
