Liquefaction process and liquefaction equipment of glucose syrup

Abstract

The invention provides a liquefaction process of glucose syrup. The liquefaction process mainly comprises the following steps: milling, size mixing, gelatinizing, sterilizing and filtering for separating, wherein the milling step comprises directly milling dry raw grains; the size mixing step comprises: firstly stirring and mixing warm water with fine grain powder for size mixing, soaking and stirring for 2-3 hours at a constant temperature condition, and adding a high temperature resistant liquefied enzyme preparation and a protein coagulant. The invention further provides liquefaction equipment of glucose syrup. The equipment comprises a primary flour mill, a primary classifying screen, a soaking tank, a jet tank for gelatinizing, at least two laminar flow tanks, a jet tank for sterilizing, a feed liquid temporary storage tank and a press filter which are serially connected in sequence. Therefore, the liquefaction process and liquefaction device of glucose syrup provided by the invention have the characteristics of simple process, high product extraction rate, reduced raw material waste, low cost, zero emission of wastewater and the like.

Description

technical field [0001] The invention relates to a liquefaction process and equipment for glucose syrup, in particular to a liquefaction process and equipment for directly producing glucose syrup from raw grains. Background technique [0002] The raw material for the conventional production of glucose syrup is "refined starch". Due to the many starch production processes and the large amount of production wastewater. One ton of starch needs to discharge 8 tons of water. Because the country has strict requirements on environmental protection and discharge, the cost of investment in sewage treatment and operation is high, which increases the production cost accordingly. As a result, the price of starch has risen a lot. [0003] The key problem of using raw grains to directly produce syrup is to separate all the proteins in raw grains. The mass fraction of protein in raw grains is generally above 7%, while the mass fraction of proteins in ordinary glucose syrup is also required...

AI Technical Summary

Problems solved by technology

[0004] Therefore, although the existing wet grinding process reduces the production cost, there is still a certain amount of wastewater discharge, which causes the loss of dissolved protein and reduces the extraction rate of the product. At the same time, there are investment and operating costs for sewage treatment facilities.
