[0039] Step 7.3, preparation of ion-free water: use tap water 5 times the volume of the resin to flow through the anion and cation exchange columns from top to bottom, and measure the conductivity of the water with a conductivity meter for many times. Put it into the ion-free water tank for standby; when the conductivity of the effluent water rises to 50mn / cm 2 , that is, when the resistance is lower than 20,000 ohms, stop making ion-free water and wait for regeneration; the anion and cation resins are soaked and washed with 5% concentration of alkali and acid respectively, and then rinse the cation resin with deionized water to PH=4. Resin to PH=9, Yin and Yang resin columns are washed in series until the conductivity of the effluent reaches 50mn / cm 2 The following is standby when the resistance is more than 20,000 ohms;
[0040] Step 7.4: Perform ion exchange treatment on the saccharification solution: After the sugar solution is cooled to below 60°C by a plate heat exchang...

[0062] The beer brewing syrup production method based on corn direct method comprises the following steps:
[0063] Step 1, peeling and degerming the corn to prepare corn flour; the dehulling and degerming process is a conventional technology, and the indicators of the obtained corn flour are: all 40 meshes of fineness pass, 60 meshes 80% pass; germ, skin yield <18%; corn flour yield ≥ 80%; soil, rocks, weeds ≤ 1%; corn flour fat content < 0.1%; corn flour moisture < 15%.
[0064] Step 2. Slurry the corn flour; add a certain amount of food-grade water into the slurry tank; add steam to raise the temperature to 58°C; add CaCl at a mass concentration of 0.3% 2 After starting the stirring of the slurry mixing tank, corn flour is continuously added into the pond by the material warehouse, and the mass percentage of corn flour and food-grade water is 39%. After adjusting the pH between 5.8-6.0, add α-amylase, which adds The amount is 6υ / g, stir evenly.

[0077] The beer brewing syrup production method based on corn direct method comprises the following steps:
[0078] Step 1, peeling and degerming the corn to prepare corn flour; the dehulling and degerming process is a conventional technology, and the indicators of the obtained corn flour are: all 40 meshes of fineness pass, 60 meshes 80% pass; germ, skin yield <18%; corn flour yield ≥ 80%; soil, rocks, weeds ≤ 1%; corn flour fat content < 0.1%; corn flour moisture < 15%.
[0079] Step 2. Slurry the corn flour; add a certain amount of food-grade water into the slurry tank; add steam to raise the temperature to 56°C; add CaCl at a mass concentration of 0.1% 2 After starting the stirring of the mixing tank, continuously add corn flour into the tank from the material bin, the mass percentage of corn flour and food-grade water is 38%, after adding the amount of flour according to the production requirements, adjust the pH between 5.8-6.0 After a while, add α-amylase in an amount ...
