Apparatus for the continuous gelatinisation of starch and starch derivatives

Apparatus for the continuous gelatinization of starch, partly degraded starch or starch derivatives by means of steam or a chemical solution, comprises a tube having at least one construction through which a starch suspension is passed, and having in the tube wall, beyond <PICT:0995660/C3/1> <PICT:0995660/C3/2> <PICT:0995660/C3/3> the constriction in the transition region to full cross-section, one or more inlet orifices for the steam or chemical solution. The constriction in the tube, e.g. a diaphragm with one or more passages or a nozzle, may be followed by a gradual widening of the tube cross-section.

Direct steam injection heater with integrated reactor and boiler

Disclosed is an apparatus for heating a viscuous liquid slurry by direct steam injection in small scale installations. A process tube, through which the slurry flows, is surrounded by a pressure vessel. The pressure vessel acts as a high pressure steam boiler tank, heating the process tube. The process tube, having a length to accommodate mixing of the slurry within, act as a reaction chamber, into which steam is injected via a direct steam injection assembly. The integration of the injector, reactor, and boiler avoids the need for an external boiler and associated plumbing.

Process and apparatus for producing starch products

1528851 Modified starch CELLCOR CORP OF CANADA Ltd 8 June 1976 [10 June 1975] 23535/76 Heading C3U [Also in Division B1] Modified starch is obtained by continuously mixing a slurry of starch into a tubular heating zone at a pressure of at least 20 kg./cm.<SP>2</SP> and at a temperature sufficient to cause the starch slurry to at least partially gelatinize and thereafter form into a hot starch liquid while moving through the heating zone; continuously passing the pressurized hot starch liquid from the heating zone through an elongated restricting zone and into a tubular reaction zone at a pressure below that of the starch liquid entering the restricting zone, whereby a highly reactive starch liquid emerges from the restricting zone into the tubular reaction zone in the form of a fine spray or mist; and continuously moving the highly reactive starch liquid through the tubular reaction zone to form a homogeneous liquid modified starch product. In the apparatus used the starch slurry feed is held in tank 10 (Fig. 1) and is fed from the outlet 11 to a pump 12 from which it is pumped at high pressure through line 13 to a diverter valve 14 and inlet 16 to reactor 17. The reactor is a closed, insulated vessel filled with heat exchange fluid and the reactor tube 18, 20 and 22 is made up of stainless steel. Coil 18 is the heating zone, coil 20 is the first reaction zone and coil 22 is the second reaction zone. The restriction zones 19 and 21 have the appearance shown in Fig. 2 where 18 and 20 are the tubes previously defined and 30 represents the elongated restriction zone.

Process and apparatus for producing modified starch products

A process and apparatus are described for producing modified starch products. In the method of the invention, 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.

Process and apparatus for producing modified starch products

Abstract of the Disclosure A process and apparatus are described for producing modified starch products. In the method of the invention, 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 confining zone within which the fluid mass is highly compressed and from the confining zone into a tubular reaction zone maintained at an elevated pressure substantially below the pressure of the starch liquid in the confining zone. A highly reactive starch liquid emerges from the confining zone into the tubular reaction zone in the form of a fine spray or mist with a sudden release of energy and contin-uously moves through the tubular reaction zone to form into a homogeneous liquid modified starch product.

Dissolving method

In a method for preparing a starch solution, particles containing starch are mixed with cold water and subjected to shear forces, such that any agglomerates formed are broken up, and each individual particle is wetted, whereupon the mixture is heated to at least about 60°C and maintained in the heated state until the viscosity maximum of the solution has passed. The wetting and the heating take place before a viscosity that is unacceptable from the point of view of handling has been reached. A device for implementing the method, a starch solution prepared in accordance with the method, and the use of such a starch solution for making paper are also disclosed.
