Abstract
The invention discloses a method for producing oxidized starch. The method comprises the following steps that: (1) 0.5 to 5 weight portion of sodium percarbonate and catalyst are dissolved with 10 to 15 weight portion of water; (2) 1000 weight portion of starch is added to be mixed perfectly; (3) the mixture is dried to ensure that the liquid water content of the starch is less than 15 percent; (4) the starch is added into a reaction jug, the temperature is adjusted between 100 and 120 DEG C, the reaction lasts 0.5 to 1 hour; (5) the step of discharging is realized, after wind cooling, the liquid water content is adjusted ranging from 11 to 14 percent; (6) the mixture is screened and bagged then. The dry method is adopted to produce oxidized starch to replace the wet method. The method for producing oxidized starch solves the problem that the waste water of the wet method for producing oxidized starch is difficult to dispose due to the high content of SO4<2->. The method has simple steps, protects the environment and has wide potential applications.
Description
Technical field
The present invention relates to Sumstar 190, specifically, relate to a kind of production method of Sumstar 190.
Background technology
Sumstar 190 has another name called treated starch or modified starch.The production method of existing Sumstar 190 generally adopts wet production, it is to add oxygenant and catalyzer in starch, high temperature down reaction generates Sumstar 190, by regulating amount, temperature of reaction and the time of oxygenant and catalyzer, thereby produces the Sumstar 190 of required viscosity.But SO in the waste water of wet production Sumstar 190
4 2-Too high levels is difficult to handle, and environmental pollution is bigger.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the existing Sumstar 190 production method, provide a kind of and can not produce waste water, the production method of the Sumstar 190 of environmental protection.
To achieve these goals, the present invention adopts following technical scheme:
The present invention adopts the dry production Sumstar 190, and it comprises the steps:
(1) with the SPC-D of 0.5～5 weight part and KBr water dissolution with 10～15 weight parts;
(2) the starch thorough mixing of adding 1000 weight parts;
(3) drying makes the starch water content less than 15%;
(4) starch is added in the retort, attemperation is 100～120 ℃, reacts 0.5～1 hour;
(5) discharging, air-cooled back re-adjustment moisture content is 11～14%;
(6) sieve back pack.
Compared with prior art, the present invention adopts following technical scheme: the present invention adopts the dry production Sumstar 190 to replace the wet production Sumstar 190, it is by the mixing ratio of control material and the temperature and time of reaction, and the waste water that has solved the wet production Sumstar 190 is because of SO
4 2-Content is high-leveled and difficult in the problem of handling.Simple and the environmental protection of method steps of the present invention has a extensive future.
Embodiment:
