Title: Improvements relating to the drying of starch
Inventor: SMITH NORMAN LESLIE
IPC: C08B30/06
Filed: 1956-02-27
Abstract: Dry starch is produced by mixing a starch cream with dry starch to form a solid cake containing 30-45 per cent moisture and then drying this in a drying machine, a proportion of the dry starch so produced being used for mixing back with further quantities of starch cream. The mixing may be effected in any suitable mixing machine by a batchwise or continuous process.  In a particular application, the starch-bearing liquor from the wheat, flour, or gluten washing process is passed continuously through a centrifugal and/or cyclonic type separator to produce a cream of preferably about 50 per cent moisture by weight.  The cream flows into a mixing machine where it is mixed with a continuous feed of dry starch.  The rate of feed of dry starch is so related to the rate of flow of starch cream that the resulting mixture contains preferably less than 43 per cent moisture by weight.  The mixing machine may be of the worm conveyer type, or of a similar type. The starch cake so produced passes through a drying machine of the tunnel type or rotating kiln type or of a type in which a rapidly moving stream of warm air carries the starch round a circuit from which it is continuously discharged when it reaches a suitably low moisture content.
