The invention relates to a method for continuously producing alkyl glucoside. According to the method, anhydrous glucose or glucose monohydrate and fatty alcohol carry out reactions continuously; then the reaction product is subjected to a continuous three grade vacuum distillation alcohol removing treatment, which comprises primary scraping plate evaporation, secondary short term evaporation, and tertiary short term evaporation, to remove fatty alcohol, and finally the reaction product is subjected to a continuous three-grade counter current discoloring treatment, which adopts ozone as the discoloring agent, so as to produce colorless, transparent, high purity and high quality alkyl glucoside. The obtained alkyl glucoside is colorless, transparent, and tasteless, and has the advantages of stable quality, high surface activity, good ecological safety, good intermiscibility, and low production cost. At the same time, the invention also relates to a production device capable of producing alkyl glucoside continuously, and has the advantages of high automation degree, short procedure, and suitability for large scale industrial production.
