Description

Technical Field

[0001] The invention relates to the field of saponin extraction, in particular to an extraction device for effective components in plants and a use method thereof. Background Art

[0002] Saponins are a class of compounds widely found in plants. They have a variety of biological activities, such as antibacterial, anti-inflammatory, and lipid-lowering. Therefore, they are widely used in medicine, health products, and cosmetics. However, the process of extracting and separating saponins from plants is a complex and diverse process.

[0003] At present, the extraction methods of saponins in plants mainly include water extraction, organic solvent extraction and ultrasonic extraction. Among them, the water extraction method is simple to operate and low in cost, but the extraction efficiency is low and the purity of the obtained saponins is relatively low. The organic solvent extraction method uses organic solvents such as alcohol and ethyl acetate to contact plant materials to separate saponins. The extraction efficiency is high and the purity is high, but the operation is cumbersome, and the use of organic solvents may cause environmental pollution problems. The ultrasonic extraction method improves the extraction efficiency through the vibration of ultrasonic waves. The operation is simple and fast, but the equipment is expensive.

[0004] In terms of separation methods, ion exchange chromatography, countercurrent chromatography and thin layer chromatography are several commonly used methods. Among them, ion exchange chromatography uses ion exchange resin to separate the target substance, and has the characteristics of good selectivity and stable separation effect, but the equipment is expensive and the operation is complicated. Countercurrent chromatography uses the separation effect of chromatographic columns, and the separation effect is stable and reproducible, but it requires professional equipment and technical support. Thin layer chromatography has low cost and a wide range of applications, but the separation effect is poor;

[0036] It should be noted that the paddle plate 19 is in an arc shape that is inclined upward. During the rotation of the paddle plate 19, it will not only scrape the inner wall of the crushing barrel 6, but its inclined upward arc shape can also support the plant material upward during rotation, so that the plant material can be fully crushed by the cutter head 18, thereby improving the crushing efficiency.
