Problems solved by technology

However, the current sugar companies use pure water throughout the entire cycle of production process. During the production process, the evaporated water is used to wash the starch without introducing natural water, resulting in low calcium ion content, and calcium ion is used as an activator to increase the speed of enzymatic reactions. The efficacy is greatly reduced, which directly affects the quality of starch liquefaction
Long-term recycling will lead to low calcium ions in the system, which will affect the light transmission and liquefaction degree of starch
In order to solve this problem, in the prior art, calcium chloride was added to the starch, and it was found that the effect was remarkable, the light transmittance of the liquefied liquid was greatly improved, the filtration rate was obviously accelerated, and the protein flocculation was better. However, due to the large amount of calcium chloride added Chloride ions cannot be removed in subsequent production, resulting in a high content of chloride ions in the product, which seriously affects the quality index of the product

Abstract

Belonging to the technical field of edible sugar production, the invention specifically relates to a liquefaction technology in an edible sugar production process. According to the liquefaction technology, calcium hydroxide is added into a starch slurry, wherein the starch dry basis and calcium hydroxide are in a weight ratio of (12500-25000):1. The liquefaction technology can significantly improve the light transmission of liquefied liquid, and reduce amylase dosage, greatly lower auxiliary material consumption, and reduce edible sugar production cost.

Description

technical field [0001] The invention belongs to the technical field of edible sugar production, and in particular relates to a liquefaction process in the edible sugar production process. Background technique [0002] In the edible sugar production process, α-amylase needs to be added in the liquefaction process to meet the liquefaction process of edible sugar production, and it is sprayed and liquefied at high temperature. However, if α-amylase is directly used in the liquefaction process of edible sugar production, the amount of amylase used is 0.6L / T (that is, 0.7-0.8 liters of amylase is required to liquefy one ton of cornstarch on a dry basis). If 2 million tons of corn starch are processed every year, the amount of amylase used is at least 1.4 million liters, the price of starch is 25.12 yuan / L, and the annual cost of amylase is 35.168 million yuan. This shows that enzyme consumption is too large in the production process, and the production cost is too high. [0003...
