The application of Ceramic membrane on sugar-free industry

With the gradual improvement of consumers' health awareness, more and more enterprises set foot in the field of sugar free. According to the investigation, some sugar free beverages mainly contain erythritol, while some sugar free products contain artificial sugar substitutes. In China's sugar production, most sugar enterprises use the traditional sulfite method to produce white granulated sugar. In the production process, chemical additives such as Cao, SO2 and polyacrylamide (PAM) need to be added, which increases the processing cost of sugar, and there will be trace residues in the finished sugar. In order to achieve high-quality clarification effect, ceramic membrane separation is gradually used as the core clarification technology.

Ceramic membrane is used to remove impurities and clarify saccharification solution

Long service life: compared with organic membrane, ceramic membrane has 3 ~ 5 times longer service life in many applications, and the separation performance remains stable, which reduces the production cost。

Narrow pore size distribution, high separation accuracy: ceramic membrane filtration level can reach nanometer level, realize high concentration. It can be separated and concentrated in a closed environment at room temperature to keep the activity of the product.

Good chemical stability, acid and alkali resistance and corrosion resistance: the ceramic membrane has strong anti microbial ability and can withstand the erosion of various media for a long time. It is suitable for the extraction and separation of various pharmaceutical components in hydrocarbons and various solvents.

Good thermal stability, easy to clean: ceramic membrane cleaning, disinfection is very convenient, not easy to make the separated system polluted, can meet the requirements of clean and sterile production in the pharmaceutical process.

The results show that the ceramic membrane has a good removal effect on protein and other impurities, reduces the pollution of ion exchange resin in the follow-up process, and reduces the amount of cleaning agent in the process of resin regeneration.

The saccharified liquid after saccharification was used as raw material, and ceramic membranes with different pore diameters were used to remove impurities and clarify saccharified liquid with different protein content, so as to improve the light transmittance and protein removal rate of clear liquid after ceramic membrane filtration, reduce the use of filter aids and the treatment of waste residue, obtain stable and high-quality sugar, and reuse the waste residue to make protein feed.
