一种乳酸链球菌素检测取样装置

Abstract

本实用新型公开了一种乳酸链球菌素检测取样装置，包括发酵罐，所述发酵罐侧面安装有与其内腔连通的取样管，所述取样管内滑动设置有活塞，且取样管侧面设置有驱动活塞移动的驱动组件，所述取样管上安装有取样阀，所述取样管外侧靠近取样阀的位置安装有与其内腔连通的排放管，且排放管上安装有排放阀。本乳酸链球菌素检测取样装置，设置有与发酵罐连通的取样管，取样管的单次取样量由设置在其内部的活塞控制，通过控制活塞滑动距离调控溶液单次取样量，提高溶液取样精度，避免单次取样过多造成浪费，取样管取样完成后关闭取样阀，切断取样管与发酵罐的连接后再将取样的溶液排出，减少外部杂菌进入发酵罐的风险。
