Problems solved by technology

This process requires a large amount of resin, and the waste water generated by resin regeneration is large, and the investment and land occupation are large, and a large number of operators are required, and there are defects such as low work efficiency and low process yield.
The applicant's previous patented technology "a method for separating and extracting glucose from starch saccharification liquid" overcomes the above defects, and at the same time provides a new type of decolorization flocculant, which has a good effect of adsorption and removal of impurities, but the flocculant is easily broken after high-temperature calcination , the regeneration ability is poor, and it will carry a certain amount of sugar molecules, resulting in a decrease in sugar yield

[0026] Step 1) Preparation of adsorbent:

[0027] Mix nano-silica, glass fiber, and deionized water in a mass ratio of 3:1:10, stir at 300rpm for 5 minutes, then add vinyltriethoxysilane accounting for 10% by mass of nano-silica, and heat up to 60°C. Ultrasonic treatment for 30 minutes to obtain a mixed material liquid; the frequency of the ultrasonic wave is 20KHz, and the power is 1000W; the mixed material liquid and polypropylene balls are mixed according to the mass ratio of 1:2, and then added to the granulator, and then added with polypropylene 10% of the mass of the ball is made of polyvinyl alcohol aqueous solution with a concentration of 7wt% to make a spherical object with a particle size of 1000um; the spherical object is dried in an oven at 80°C for 60 minutes, and then put into a sintering furnace for sintering, and the sintering temperature is 650°C , keep it warm for 30min, tak...

Embodiment 2

[0039] A separation and purification process for glucose, comprising the steps of:

[0040] Step 1) Preparation of adsorbent:

[0041] Mix nano-silica, glass fiber and deionized water according to the mass ratio of 5:2:20, stir at 300rpm for 5min, then add vinyltriethoxysilane accounting for 10% by mass of nano-silica, and heat up to 60°C. Ultrasonic treatment for 30 minutes to obtain a mixed material liquid; the frequency of the ultrasonic wave is 20KHz, and the power is 1000W; the mixed material liquid and polypropylene balls are mixed according to the mass ratio of 1:2, and then added to the granulator, and then added with polypropylene 10% of the mass of the ball is made of polyvinyl alcohol aqueous solution with a concentration of 7wt% to make a spherical object with a particle size of 500um; the spherical object is dried in an oven at 80°C for 60 minutes, and then put into a sintering furnace for sintering, and the sintering temperature is 650°C , keep it warm for 30min...

Embodiment 3

[0053] Soak the used adsorbent in water at 50-60°C for 30 minutes, take it out, and calcinate it at 400-500°C for 3 minutes to remove the adsorbate, cool it naturally, and then use it again. The regeneration of the adsorbent is achieved, and the adsorption effect is not good. obvious change.
