药材水提真空浓缩装置

Abstract

本实用新型公开了药材水提真空浓缩装置，包括浓缩釜、真空泵和集水箱。有益效果：本实用新型采用了冷凝器和气水分离器，在进行药材水提过程中，可将药材和提取液放入到浓缩釜中，随后启动加热器和真空泵，并将冷凝器接通工业冷水机，真空泵依次通过第二连接管、第三连接管和第一连接管抽出浓缩釜内部的气体，降低浓缩釜内部的气压，从而降低浓缩釜内部提取液的沸点，加速水分蒸发，避免温度过高导致药材成分失效，同时，显著提高了浓缩速度和工作效率，同时，被抽出的蒸汽首先进入到冷凝器中，经过冷凝器冷凝后形成水，较为干燥的气体进入到气水分离器中，进一步气水分离，干燥的空气经过真空泵的抽取后排出，避免水汽进入到真空泵中。
