This utility model relates to the field of reaction vessel technology, and in particular to a reaction vessel for the production of glyceryl citrate stearate. It includes a fixed ring, inside which the reaction vessel body is fixedly installed. A protective cover is fixedly installed on the top of the reaction vessel body, and a stirring structure is provided on the top of the protective cover. Simultaneous driving of two electric push rods on both sides causes the telescopic rods to move the mounting plate downwards, thereby causing two second inclined plates to move downwards. Since the inclined edges of the two second inclined plates are in contact with the inclined edges of the first inclined plate, the downward movement of the second inclined plates causes the first inclined plate to extend its telescopic rod from the side rod, thereby causing the polytetrafluoroethylene scrapers on both sides to expand outwards and contact the inner wall of the reaction vessel body. At this point, the servo motor is restarted, causing the rotating rod to drive the polytetrafluoroethylene scrapers to rotate, thus scraping off the deposits on the inner wall of the reaction vessel body. Afterwards, the vessel can be rinsed with clean water, thus achieving the purpose of scraping off deposits on the inner wall after the reaction.
