Tannic acid extraction and concentration device

The utility model relates to a tannic acid extracting and concentrating device which comprises a top cover, a reactor, a circulating pipeline, a pressure pump, a pressure gauge and a supporting column, a plate frame is arranged, a motor provides driving force for a rotating block, the conical plate frame rotates in a reaction chamber and strengthens stirring acting force for substances in the reaction chamber, and due to the structural property of rotating beads, the tannic acid is extracted and concentrated. The auxiliary conical plate frame swings at a certain angle, the elasticity of the telescopic arc rod is matched with the elasticity of the spring, so that the arc frame can enter and exit from the two side ends of the sleeve plate back and forth, the tough rod is driven to continuously act between substances which react with each other, liquid substances are stirred, and the extraction and concentration reaction efficiency is improved. 本实用新型涉及单宁酸提取浓缩装置，包括顶盖、反应器、循环管道、压力泵、压力表和支撑柱，通过设置了板架，电机为带转块提供驱动力，锥形板架在
