Abstract

The water content of a starch slurry is lowered to a level of 33-45% when the slurry is dewatered, by adding to the slurry a minor proportion of an oxyalkalene-containing compound having surface-active properties, which compound has the property of reducing the water content of the slurry below that which results from dewatering the slurry without the use of such a compound; and dewatering the slurry. The preferred amount of the compound is 0,1%, but from 0,02% may be added. The starch may be that derived from corn, wheat, potato, tapioca, sago or cassava and may be in the form of raw starch, lightly treated oxidized starch, heavily treated oxidized starch or thin boiling starches. The compounds may be divided into 12 groups in which the following substances are specified:-Group (1) Polyoxyethylene-dilaurate, -monolaurate, -monostearate, and polyoxyethylene esters of mixed fatty and resin acids; (2) Polyoxyethylene sorbitol-pentalaurate, -hexalaurate, -4,5 oleate, -tetraoleate, -tetra-tall oil, and -dilaurate; (3) Polyoxyethylene sorbitan-monostearate, -dilaurate, -trioleate, and -monolaurate; (4) Sorbitan monolaurate and mono-oleate; (5) Diethylene glycol monolaurate; (6) Glyceryl-monolaurate, -oleostearate,-monostearate, or-monoricinoleate; (7) Polyoxypropylene stearate; (8) Polyoxyethylene lauryl ether; (9) Polyxyethylene lauric acid laurate; (10) Glycerol mannitan laurate; (11) A condensation product of polyoxypropylene and polyoxyethylene; (12) Nonyl phenoxypolyoxyethanol.ALSO:The water content of a starch slurry is lowered to a level of 33-45% when the slurry is dewatered, by adding to the slurry a minor proportion of an oxyalkylene-containing compound having surface active properties, which compound has the property of reducing the water content of the slurry below that which results from dewatering the slurry without the use of such a compound; and dewatering the slurry.
