Embodiment 1
[0020] Using corn starch as raw material, take a certain amount of corn starch, add water to make 16-20Be' starch milk, add β-amylase, adjust the pH value to 6.0-6.4, import it into a water heater for hydrolysis and liquefaction, and adjust the water heater The upper material enters the distance, controls the pressure difference between the inlet and outlet materials to 0.20MPa, adjusts the pressure and temperature of the steam introduced into the water heater, and controls the primary cooking temperature to 120°C. The clear liquid of the lower layer of the hydrolyzed liquefied product liquefied liquid is pumped to the flash tank for flash evaporation, and the protein slag flocculated in the upper layer is extracted and removed. The material after flash evaporation is then introduced into the saccharification tank for saccharification, and then undergoes decolorization, ion exchange and concentration to obtain a kind of maltose.
Embodiment 2
[0022] Using cornstarch as raw material, take a certain amount of cornstarch, add water to prepare 16-20Be' starch milk, add glucoamylase, adjust the pH value to 6.0-6.4, import it into the water heater for hydrolysis and liquefaction, and adjust the temperature of the water heater. The material enters the distance, controls the pressure difference between the inlet and outlet materials to 0.18MPa, adjusts the pressure and temperature of the steam introduced into the water heater, and controls the primary cooking temperature to 125°C. The clear liquid of the lower layer of the hydrolyzed liquefied product liquefied liquid is pumped to the flash tank for flash evaporation, and the protein slag flocculated in the upper layer is extracted and removed. The material after flash evaporation is then introduced into the saccharification tank for saccharification, and then undergoes decolorization, ion exchange and concentration to obtain a kind of glucose.
Embodiment 3
[0024] Using corn starch as raw material, take a certain amount of corn starch, add water to make 16-20Be' starch milk, add isomerized glucose enzyme, adjust the pH value to 6.0-6.4, import it into the water heater for hydrolysis and liquefaction, and adjust the water heater The upper material enters the distance, controls the pressure difference between the inlet and outlet materials to 0.16MPa, adjusts the pressure and temperature of the steam introduced into the water heater, and controls the primary cooking temperature to 130°C. The clear liquid of the lower layer of the hydrolyzed liquefied product liquefied liquid is pumped to the flash tank for flash evaporation, and the protein slag flocculated in the upper layer is extracted and removed. The material after flash evaporation is then introduced into the saccharification tank for saccharification, and then undergoes decolorization, ion exchange and concentration to obtain a kind of fructose.
