Description

Technical Field

[0001] This utility model relates to the field of isoliquiritin preparation technology, specifically to a separation device for low-energy isoliquiritin preparation. Background Technology

[0002] Isoliquiritin, a flavonoid compound with significant pharmacological activity found in licorice, has long been a focus of research in the field of natural product separation due to its extraction and preparation processes. Traditional isoliquiritin extraction methods typically rely on organic solvent extraction, acid hydrolysis, or enzymatic hydrolysis. Solvent extraction methods often use ethanol, methanol, or aqueous solutions of alcohols in varying proportions as the extraction medium, dissolving the target component from the licorice raw material through methods such as heating and reflux or percolation. Acid hydrolysis utilizes acidic conditions to convert precursors such as glycyrrhizin into isoliquiritin, followed by separation and purification. While these methods have some application in industrial production, the entire extraction process involves multiple unit operations, including raw material pretreatment, extraction, filtration, concentration, and purification. The process is relatively lengthy, and the control of process parameters at each stage directly affects the yield and purity of the final product.

[0003] Existing technologies still have many shortcomings in practical applications that urgently need improvement. On the one hand, conventional pulverization pretreatment methods often fail to fully disrupt the cell walls of licorice plants, resulting in high dissolution resistance and low mass transfer efficiency of isoglycyrrhizin during subsequent extraction. This not only prolongs the extraction time but also increases solvent and energy consumption. On the other hand, temperature control during the extraction process is not precise enough. Local overheating can easily cause degradation or isomerization of heat-sensitive isoglycyrrhizin, affecting product activity. Therefore, we propose a low-energy separation device for isoglycyrrhizin preparation. Utility Model Content

[0016] The working principle of the low-energy separation device for isoglycyrrhizin preparation provided by this utility model is as follows: First, licorice raw material enters the connecting tank 11 through the feeding frame 6, and is efficiently crushed by the crushing component 2.
