PRODUCTION APPARATUS AND PRODUCTION METHOD FOR SUCROSE-6-ESTER
Document Type and Number:
WIPO Patent Application WO/2022/174382
Kind Code:
A1
Abstract:
A production apparatus and production method for sucrose-6-ester; said apparatus comprises a tank body, a heating pipe, an annular cooling device, and a motor; the annular cooling device and the heating pipe are sequentially nested in the tank body from inside to outside; the annular cooling device comprises a condensation inner wall, condensation pipes and a condensation outer wall which are sequentially nested from inside to outside; the heating pipe and the tank body form a distillation cavity, the heating pipe and the condensation outer wall form a condensation cavity, and the hollow portion of the condensation inner wall is a reaction cavity; the motor is electrically connected to the heating pipe and the condensation inner wall and can drive the heating pipe and the condensation inner wall to rotate, so that a reaction liquid is separated into water vapour and distillation residue; and a vapour outlet is provided on the heating pipe, so that the water vapour can enter the condensation cavity from the distillation cavity; a distillation residue channel is provided at the end of the heating pipe away from a feeding port; and the distillation residue channel is arranged not in contact with the annular cooling device and is in communication with the reaction cavity. Said apparatus allows for the continuous production of sucrose-6-ester, greatly shortening a production period.
