Embodiment 1
[0033] Add 100ml of water into the sealed tank, and connect the air pump and feeding device to the outside of the sealed tank; sieve the starch and diatomaceous earth so that the starch and diatomite have no agglomeration; gradually add 10g of sieved starch to the sealed tank for hydrolysis, And keep stirring for 30min, and keep the temperature at 55-75°C; after cooling the stirred solution to room temperature, add two-thirds of 750ml sodium hypochlorite solution to the stirred solution and stir for 1h, the stirring speed is 60r / min; Gradually add 176g of crystalline glucose into the sealed tank, and keep stirring for 20 minutes, and keep the temperature at 20-30°C; slowly continue to add the remaining third of the sodium hypochlorite solution to the solution that has been stirred and reacted, and stir for 1 hour; 9 g of diatomaceous earth was added to the solution and stirred for 30 minutes; the stirred solution was left to stand for 24 hours and then filtered, and the sodium ...
