Production method of glucolactone

Abstract

The invention discloses a production method of glucolactone, comprising the following steps: 1. ceramic membrane filtration and impurity removal: fermentation liquid is filtered by ceramic membrane filtration equipment to obtain sodium gluconate dialysate; 2. continuous fluid separation and conversion: the sodium gluconate dialysate enters into a continuous fluid separation device to carry out continuous ion exchange, so as to lead the sodium gluconate to be converted into sodium gluconate solution; 3. antiosmosis concentration: gluconic acid solution flown out from the continuous fluid separation device is contracted by an antiosmosis system to obtain gluconic acid concentrated solution; 4. crystallization: glucolactone inoculating crystal is added in the gluconic acid concentrated solution, so as to obtain the glucolactone. The method utilizes the ceramic membrane filtration to replace filter-bag filtration in the traditional process, adopts continuous fluid separation device to replace fixed bed ion exchange and uses fixed bed ion exchange to concentrate the gluconic acid, so as to improve the production yield of the glucolactone and reduce the production cost; the production method has the characteristics of energy saving and environmental protection.
