一、Process Flow

二、Process Description

(1) Adjustment of starch milk: adjust the concentration of starch in the starch factory to 17-19Be with water, and adjust the pH value and temperature.

(2) Liquefaction: Transfer the starch milk to the buffer tank, add the appropriate amount of enzyme preparation, and use the ejector to heat and mix to keep warm and liquefy.

(3) Saccharification: lower the temperature of the liquefied liquid to a certain temperature, adjust the pH value, add an appropriate amount of enzyme preparation, and deliver it to the saccharification tank, saccharify to the required maltose content within a specified time, and then kill the enzyme to discharge.

(4) Filtration and decolorization: The maltose syrup passes through the filter to remove protein and other impurities, then add activated carbon at the appropriate temperature to decolorize within a specified time, and then send it to the filter to remove the activated carbon, and the clear liquid is sent to the next process.

(5) Ion exchange: At a certain temperature, the maltose solution enters the cation resin and anion resin exchangers to remove inorganic salts and pigments and other organic impurities to obtain refined filtrate.

(6) Evaporation: The maltose liquid is sent to the evaporator through a precision filter for concentration to achieve the desired product concentration.

(7) Finished product packaging: maltose products are filled and weighed, and packed and stored in the warehouse.
