Plant extracts (such as traditional Chinese medicine, tobacco, natural flavors and fragrances) are enriched by enrichment through solvent extraction. The wiped film evaporation concentration system has a high degree of vacuum, thereby reducing the evaporation temperature of the material; At the same time, the residence time of the material in the wiped film evaporator is short, which can reduce or avoid the influence of heat on the material for a long time. Through years of research, our company can provide customers with mature plant extract low temperature concentration system solutions.
