Embodiment 1

[0027] A new process for purifying saccharification liquid, the steps are as follows, (1) pulping: adjust the Baume degree of cornstarch milk to 17°±0.5Bé with water in the pulping tank, and then add Na with a mass fraction of 5-10% 2 CO 3 The pH of the solution to the slurry mixing tank is 5.5-6.0, and finally the starch milk adjusted in the slurry mixing tank is pumped into the feeding tank;

[0028] (2) Liquefaction: The liquefaction section adopts the process of 2 times of jet liquefaction and 4 times of flash evaporation. One third of the liquefaction enzyme is added for one jet liquefaction, the temperature is maintained at 110°C for 1 minute, and then flashed and cooled to 95°C for 20 minutes; The second jet liquefaction raises the temperature of the starch milk to 135°C and maintains it for 15 seconds, then flashes the temperature to 93°C and adds the remaining two-thirds of the liquefying enzyme, reacts for 90 minutes, and then the liquefied liquid undergoes three fla...

Abstract

The invention belongs to sugar production methods, and particularly relates to a novel process for purifying saccharification liquid. The novel process includes the steps: (1) size mixing; (2) liquefaction; (3) saccharification; (4) discoloration; (5) hybridization; (6) chromatographic pre-evaporation evaporation and concentration; (7) chromatographic separation.

Description

technical field [0001] The application belongs to the production method of sugar, in particular to a new process for purifying saccharification liquid. Background technique [0002] The sugar solution with a DX value of 99.5% and above is obtained by using the traditional method of material crystallization and separator separation, that is, corn starch milk is processed through pulping, liquefaction, saccharification, decolorization, separation, evaporation concentration, crystallization, and separation. Afterwards, the isolated crystals were redissolved in pure water. This traditional method has long period, high energy consumption and low product yield. [0003] This application takes patents CN2017214368200 and CN2017214368215 as priority. Contents of the invention [0004] In order to solve the problems existing in traditional methods, this patent has designed a new process for purifying saccharification liquid, and this application is realized through the following ...
