Abstract

The invention discloses a novel granularity-controllable sucrose refining method which comprises the steps: dissolving and decoloring food-grade sucrose to obtain refined filtrate, concentrating and crystallizing the refined filtrate to obtain sucrose crystals, and purifying and drying the sucrose crystals to obtain medicinal-grade sucrose crystal grains. A crystallization method combining seed crystal graining and ultrasonic stimulation assisted graining is creatively adopted; the seed crystal adding time, the seed crystal adding amount, the ultrasonic frequency, the ultrasonic stimulation crystallization time, the stirring speed and other parameters are accurately controlled; the method effectively controls the particle size of the medicinal sucrose crystals, enhances the sucrose crystallization yield, and implements the characteristics of small particle size, favorable flowability and favorable solubility of the medicinal sucrose crystals, thereby satisfying the performance requirements for the medicinal sucrose auxiliary material in the direct-pressure solid preparation.

Description

technical field [0001] The invention relates to the technical field of sucrose refining, in particular to a novel sucrose refining method with controllable particle size. Background technique [0002] Sucrose has been used as a pharmaceutical excipient at home and abroad for hundreds of years, and it has an even longer history as a food. It is used as excipient, flavoring agent, coating agent, granulating agent, suspending agent, sweetener, filler, therapeutic agent, thickening agent, etc. in pharmacy. 85% syrup or aromatic syrup is used as a flavoring agent for oral liquid preparations, 50% to 67% of syrup is used as a binder for wet granulation, sucrose powder can be used as a dry binder, and compressible sucrose can be used as a dry pressing agent. Binder for tablets, filler and sweetener for chewable tablets and lozenges. Therefore, medicinal sucrose is widely used in the production of solid preparations, and is used in large quantities as an important filler and flavo...
