Embodiment Construction

[0026] The 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. Under the condition that the temperature of the steam in the kettle reaches 140 °C, let the cornstarch be fully stirred in the kettle to make it heated evenly. Stir for about 50 minutes. At this time, the starch in the kettle has been matured, and the properties of its own original starch have fundamentally changed (this link is commonly known as the frying process).

[0029] 2. Feeding

[0030] Take out the neutralized (fried) starch from the reactor, put it in a 1000-liter stainless steel reaction tank, pour water and stir, so that the starch is soaked fully, evenly without particles, and the liquid starch concentration is about 60% (or The Baume degree of starch solution is about 60°).

[0031] 3. Precipitation

[0032] Suction out the completely dissolved liq...

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 technology for deep processing of starch. Background technique [0002] High-strength modified starch is an important part of starch deep-processing products. High-strength modified starch is based on native starch (also known as natural starch) as the main raw material, and is modified by chemical, physical or biological methods to change the physical properties of raw starch. , chemical properties. [0003] High-strength modified starch is a novel raw material for many industrial sectors. For example, in the textile industry, high-strength modified starch is used to replace vinyl pulp to form a new pulp 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 inter...
