Description

Chinese yam-based saponin extraction equipment Technical Field The invention relates to the technical field of yam saponin extraction, in particular to yam-based saponin extraction equipment. Background The yam is used as a traditional crop with homology of medicine and food, is rich in various bioactive components, wherein the saponin compounds have been proved by modern researches to have obvious physiological functions of resisting inflammation, regulating immunity, resisting tumor, reducing blood fat, protecting cardiovascular and the like; the traditional saponin extraction process usually adopts solvent extraction methods, such as hot water extraction, alcohol extraction (such as methanol and ethanol) or water-alcohol mixed solution extraction, and utilizes the dissolution characteristics of the saponins in solvents with different polarities to carry out mixed extraction on the pretreated yam raw materials and the solvents at a controllable temperature, and the extraction and purification of the saponins from plant cells and tissues are promoted by means of auxiliary heating, stirring and the like; in the specific extraction process, the crushed yam materials and the solvent are mixed in an extraction tank, heated by a jacket or a coil pipe and continuously moved by means of a stirrer, wherein the process aims at destroying the plant cell structure and promoting the intracellular saponin components to be fully released to the solvent phase; However, in the middle and later stages of saponin extraction, along with continuous dissolution of saponin molecules and other co-solvents (such as polysaccharide, protein and the like), the extraction liquid system tends to have complex physicochemical property changes, the saponin has surface activity and amphipathy, which easily causes liquid to generate foam, and possibly interacts with other components to form colloid or complex, so that the viscosity of the system is obviously increased, and the system exhibits non-Newtonian fluid behavior, the change often causes serious phase separation and mass transfer barriers in an extraction tank, namely, insoluble residues and fibrous tissues with higher density are settled at the bottom of the tank under the action of gravity to form a compact 'sediment layer', the dissolved saponin, colloid and certain hydrophilic components are easy to float upwards or aggregate near the liquid level due to the viscosity increase and the surface activity effect, so that a viscous 'enriched layer' or stable emulsion area is formed, the effective solid-liquid mass transfer area is limited in a limited middle space, the solvent is difficult to effectively permeate into the bottom sediment layer, and the upper effective components cannot be fully exchanged with fresh solvent, the result is often shown as 'residue on the bottom of the tank' and oversaturated 'can be separated from the bottom of the tank', and the energy consumption of extraction equipment is reduced only because of the subsequent extraction and the energy consumption is reduced.
