Embodiment Construction

[0026] Production process of high-strength modified starch:

[0027] 1. Neutralization reaction:

[0028] Pour 400 kg of cornstarch into the enamel reaction kettle and inject steam while stirring with a motor. When the steam temperature in the reaction kettle reaches 140°C, let the cornstarch be fully stirred in the kettle so that it can be heated evenly. Stir for about 50 minutes. At this time, the starch in the kettle has matured, and the properties of the original starch itself have fundamentally changed (this link is commonly called the frying process).

[0029] 2. Feeding

[0030] Take out the starch that has been neutralized (fried) from the reaction kettle, put it in a 1000 liter stainless steel reaction tank, fill it with water and stir, let the starch soak fully, evenly and without particles, so that the concentration of liquid starch is about 60% (or called The Baume degree of starch solution is about 60°).

[0031] 3. Precipitation

[0032] Suck out the complete...

Abstract

The present invention provides a method for producing high intensity modified starch, including a neutralization reaction, casting stock and precipitating; a clarified starch solution is sucked into a reaction tank, aqueous vapor is injected into the reaction tank, then the clarified starch solution is heated until 65 DEG C, during which agitating the solution continually to play a function of conditioning and high-temperature enzyme extinguishing, the heating and agitating time is from 20 to 40 minutes; then wood carbon dust is added to discolor and desludge; a clear starch solution will be obtained after filtering by a compressor; the impurity in the starch is removed step by step by steps of concentrating, batching and high speed centrifugation, the technique is reasonable, the high intensity modified starch has high purity and adequate quality, and the product grade is improved.

Description

technical field [0001] The invention belongs to the technical field of deep processing of agricultural products, in particular to a starch deep processing technology. Background technique [0002] High-strength modified starch is an important part of starch deep-processing products. High-strength modified starch uses raw starch (also known as native starch) as the main raw material, and is denatured by chemical, physical or biological methods to change the physical properties of the original starch. , Chemical properties. [0003] High-strength modified starch is a new type of raw material in many industrial sectors. For example, in the textile industry, high-strength modified starch is used to replace vinyl size to form a new type of size that does not pollute the environment and is harmless to the human body. Another example is the papermaking and paper products industry, using high-strength modified starch as various additives, sizing agents, and binders can improve the...
