  • Patent number: 10239958
    Abstract: A process for modifying starch comprises atomising an aqueous slurry of non-pregelatinised starch into an internal chamber in a bi-fluid nozzle of a spray dryer and treating the atomized slurry, in the internal chamber, with superheated steam to cause partial gelatinisation of the starch. The aqueous slurry containing partially gelatinised starch is discharged through an outlet in the internal chamber into a reactor where the droplets containing the partially gelatinised starch are subjected to further treatment with superheated steam, resulting in the completion of the gelatinisation of the starch in the reactor. Also disclosed is a bi-fluid nozzle for use in spray drying starch which comprises a nozzle body, a nozzle cap and an internal chamber located between the nozzle body and the nozzle cap.

  • 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.

    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.

In the process a starch slurry is continuously moved through a confined tubular preheat zone where heat is very rapidly transferred to the slurry, whereby the slurry passes through a gelation stage and forms into a hot free flowing liquid. The heat transfer is from superatmospheric steam surrounding at least part of the tubular heating zone, the temperature of the steam and the cross-sectional area of each tubular preheat zone being selected to rapidly transfer heat from the steam throughout the slurry and minimize the magnitude of the zone of high viscosity gel formed during the gelation stage. The hot liquid formed is immediately forced through a restrictive opening and into a confined tubular reaction zone accompanied by a sudden decrease in pressure whereby the starch is made highly reactive.

  • Patent number: 4230503
    Abstract: A process and apparatus for producing modified starch products. A slurry of starch is continuously moved at elevated temperature and pressure through a tubular heating zone and the hot fluid mass emerging from the heating zone is forced through a flow restricting zone within which the fluid mass is highly compressed. This highly compressed fluid material emerges from the confining zone into a tubular reaction zone with a sudden release of energy in the form of a fine spray or mist. The compressive forces followed by the sudden energy release act on the starch molecules to temporarily greatly increase the reactivity of the starch within the reaction zone, whereby modified starch products are quickly formed.

  • Patent number: 4221609
    Abstract: A continuous process for the production of starch hydrolysates, such as corn syrup. The process comprises continuously moving an aqueous acidic starch slurry feed through a confined preheat zone at a pressure of at least 300 psi to raise the temperature of the slurry to at least 100.degree. C., continuously forcing the hot fluid mass emerging from the preheat zone through an elongated compressing zone, continuously receiving the fluid material emerging from the compressing zone in the form of a fine spray or mist including water vapor in a confined zone of reduced pressure and continuously collecting from said reduced pressure zone a homogeneous starch syrup having a higher solids content than the starch slurry feed. The temperature and pressure of the hot fluid mass entering the elongated compressing zone and the acidity of the feed slurry can be controlled to selectively provide syrup products having a wide range of DE values.

  • Patent number: 4201596
    Abstract: A continuous process for effecting the acid hydrolysis of cellulosic waste materials, at high solids and in a most economically desirable manner. The process may be controlled to produce, as primary products, glucose, furfural and/or xylose. By appropriate control of water and temperature, through the use of direct steam injection, high solids feedstocks may quickly be converted, in good yields, to valuable products, thus making the process very attractive from a practical commercial standpoint.

  • Patent number: 4137094
    Abstract: A continuous process for the production of starch hydrolysates, such as corn syrup. The process comprises continuously moving an aqueous acidic starch slurry feed containing at least about 35% by weight starch solids through a confined preheat zone at a pressure of at least 300 psi to raise the temperature of the slurry to at least 140.degree. C, continuously forcing the hot fluid mass emerging from the preheat zone through an elongated compressing zone, continuously receiving the fluid material emerging from the compressing zone in the form of a fine spray or mist including water vapor in a confined zone of reduced pressure and continuously collecting from said reduced pressure zone a homogeneous starch syrup having a higher solids content than the starch slurry feed. The temperature and pressure within the elongated compressing zone can be controlled to selectively provide syrup products having a wide range of DE values.
