Embodiment 1

[0047]A device suitable for high-temperature drying corn to prepare starch sugar, including a starch milk separation unit disc separator for separating crude starch milk, a starch lotion unit, a solid-phase separation unit for separating liquefied liquid after starch lotion, and a saccharification flocculation unit for saccharification and protein flocculation.

[0048] The solid phase separation unit for separating liquefied liquid after starch lotion includes a primary cooling device, a horizontal screw centrifuge connected with the primary cooling device and a secondary cooling device connected with the liquid phase separation port of the horizontal screw centrifuge. After the primary cooling, the liquefied liquid is separated from the light phase and the heavy phase by the horizontal screw centrifuge, and the light phase enters the saccharification flocculation unit for saccharification after the secondary cooling. Protein drying device 4 connected to the solid phase separatio...

Embodiment 2

[0062] (1) The crude starch milk processed by high-temperature drying corn is separated by a disc separator to obtain gluten water and starch milk. The feed concentration of crude starch milk in the main separation disc separator is 10.0b é. After separation by the separator, the underflow concentration is 17.7b é and the top stream dry matter content is 2.5%;

[0063] (2) After liquefaction, the liquefied liquid with a temperature of 95 ℃ enters the plate heat exchanger for primary cooling, and the temperature of the liquefied liquid is reduced from 95 ℃ to 80 ℃ by adjusting the cooling water flow of the plate heat exchanger;

[0064] (3) The liquefied liquid after primary cooling enters the horizontal screw centrifuge for separation, and the feed flow is 13m 3 / h. The solid content in the feed is 1.2%, and the parameters of horizontal screw centrifuge are differential speed 10rpm and separation factor 3000. After separation by horizontal screw centrifuge, it is separated into so...

Abstract

The invention relates to a device and method suitable for preparing starch sugar by drying corn at high temperature. The method is as follows: increasing the feed concentration of coarse starch milk obtained by corn processing, separating it through a disk separator to obtain starch milk with reduced gluten water and modified starch content, and then emulsifying and separating the starch to obtain Starch milk light phase, the starch milk light phase is saccharified, and the saccharification solution after saccharification is subjected to protein flocculation, and post-processing to obtain starch sugar. It can reduce the content of modified starch in starch milk, greatly improve the effect of liquefaction and saccharification, and the overall production effect is significantly improved.

Description

technical field [0001] The invention relates to a device and method suitable for preparing starch sugar, in particular to a device and method for preparing starch sugar with high-temperature dried corn as raw material. Background technology [0002] As a sweetener, starch sugar is widely used in food, beverage and other industries. Corn starch is the main raw material for the production of starch sugar. The general preparation process of producing starch sugar from corn starch is as follows: firstly, the corn is processed into corn starch or starch milk through the traditional wet processing process, and then the starch or starch milk is processed into starch sugar through a series of processing processes such as slurry mixing and liquefaction. [0003] As a kind of crop, due to the difference of planting area, climate and other conditions, the moisture content of corn grain is different after maturity. In order to facilitate long-term storage, the moisture content needs to be re...
