The invention relates to a process for producing erythritol by utilizing Yarrowia lipolytica strains, belonging to the technical field of fermentation engineering. In the process, artificial breeding and reproduction is carried out on Yarrowia lipolytica screed in nature so as to produce erythritol, wherein the steps of strain culture of Yarrowia lipolytica and production of erythritol with the strains comprise: strain preparation, primary and secondary seed culture, fermentation to obtain fermentation broth, ceramic membrane filtration, nanofiltration, evaporation and concentration, activated carbon decolorization, ion exchange, vacuum crystallization, auxiliary crystallization, centrifugation, drying, screening and package. In the invention, a mother liquid obtained by centrifugation reaches the standard of ceramic membrane filtrate after being subjected to nano filtration and purification, thus the ceramic membrane filtrate can be mixed and enters into the next process, thereby greatly improving the yield of the product; and the purity of the finished product is more than 99.5%, and the moisture of the finished product is about 0.16%. The process has the advantages of low production cost, short fermentation period, high production efficiency and the like.
