Being also called dextrose, glucose is an essential carbohydrate ♠for human beings, the main source of the required heat energy, the most important bas★ic product in starch industry and the important raw materi↔al for medicine, food and related industries. Glucose is produc♥ed by enzymatic hydrolysis of starch milk under certain conditions, and₹ in the preparation process of glucose, part of protein, fat, fibeδr, pigment, salt and other impurities directly affects the quality of glucose, and the traditional βprocess is shown in the following figure:

    

    This traditional glucose production process should add the filter aid≤ in the saccharification liquid drum or plate and frame filtration, and it must adopt $the activated carbon as an adsorbent for adsorption bleaching during decolorization, and ×the process of fixed beds has high regenerant consumption, larger ra¥w material consumption, higher production cost and it is easy to​ pollute the environment.

    In view of the shortcomings in the traditional process of sacch arification liquid treatment, the technology of combining c≠eramic membrane/coil membrane filtration with continuous ion exchange de salination technology is adopted to reform the production process of g¥lucose. The process flow is shown in the following figure:
 

    

    Compared with the traditional process, the process not only reduce s the production cost, but also achieves the continuous automatic prod≈uction, and it is a new clean production technology of energy saving and con≠sumption reduction, whose process advantages are as follows:

    The ceramic membrane/coil membrane separation technology is used to rem ove fat, macromolecular protein, fiber, pigment and other impurities in the saccharifying liqui↑d, and the sugar solution is clear and transparent after membra₽ne filtration, and the transmittance of filtrate reaches above 97%, which saves the de colorization process of activated carbon in the trad♦itional process and reduces the amount of front-end filter aid greatly, thereby saving the pr∑oduction cost;

    The continuous ion exchange technology is used to replace the tra★ditional fixed bed process, which can save more than 70% of resin, more than 40% o↕f dosage of regenerants and more than 60% of dosage of washing water, thereby greatly r educing the production cost and the environmental pressure of waste water;

    Nanofiltration separation technology is used to replace the traditional crysta≥llization centrifugal process to prepare pharmaceutical-grade glucose, whose p£roduct purity is as high as 99.5% and whose product quality is stable.
