一种逆流浸出装置
一种逆流浸出装置,属于动植物提取设备
技术介绍
动植物原料浸出是指采用适当的溶剂或方法,从动植物原料(全部或者某一部分)中提取加工获得有效成分(有效成分能溶于溶剂)。在现有工业大规模生产中,动植物原料中有效成分的提取方式,多采用将动植物原料干燥、压片获得片状原料,将片状原料喷淋溶剂,获得提取液,然后进行分离精制(如萃取、蒸馏)。申请人在研究中发现,现有的浸出装置存在以下问题:首先,现有的浸出装置有效成分的收率低、提取效率低,在对有效成分提取时,提取原料通常沉积在溶剂底部,从而导致原料无法与溶剂充分接触,导致原料的有效成分浸出效率低,需要很长时间才能将原料中的有效成分充分提取,大大提高了时间成本。
