Title:
PRODUCTION EQUIPMENT AND PRODUCTION METHOD FOR SUCROSE-6-ESTER
Document Type and Number:
WIPO Patent Application WO/2022/155947
Kind Code:
A1
Abstract:
Production equipment and a production method for sucrose-6-ester, wherein the equipment comprises a housing, a film scraping device, and a base. The film scraping device is disposed on the base, and the housing covers the outer sides of the film scraping device and the base. The housing is provided with a reaction liquid feeding port and a condensed water outlet. The base is provided with a carboxylic ester feeding pipe, a reaction product discharging pipe, and a reaction channel connected to the carboxylic ester feeding pipe. The film scraping device comprises a temperature control device, a rotating pipe, and a plurality of scraping blades disposed on the inner wall of the rotating pipe. The outer edges of the scraping blades abut against the outer wall of the temperature control device. The rotating pipe can rotate around the temperature control device, so that the scraping blades can scrape a reaction liquid that enters from the reaction liquid feeding port and flows down along the outer wall of the temperature control device into a liquid film on the outer wall of the temperature control device, and separate the liquid film into an evaporation residue and water vapor. According to the equipment, the integrated design of a separation device and a reaction device is realized, the volume of the production equipment is reduced, floor space is saved, the yield of sucrose-6-ester is improved, and the production cost is greatly reduced.
