a blending mixer

Abstract

A blender. It is mainly used in container equipment used in cell culture in biological fermentation, pharmaceutical and other process fields. It consists of a stirring paddle system composed of blades, connecting rods, and shaft sleeves, a motor, and a stirring shaft. The blades that make up the stirring paddle system are "ten" windmills, and the ends of the blades each have a tilt with an acute angle of 45 degrees, and the tilt is parallel to the same "ten" connecting the bisector of the top angle. Due to the use of such a blade structure, when the motor drives the stirring shaft and the stirring paddle system to run clockwise, the blades also rotate clockwise and gently touch the cells in the mixture under the action of the liquid's stress, so as to achieve uniform stirring and make cells from damage. One set of stirring paddles has two sets of left and right symmetrical blades. In order to further achieve the effect of stirring evenly, the agitator has two sets of stirring paddles up and down.

Description

Technical field: [0001] The invention is a blending type agitator. It is mainly used in container equipment used in cell culture in biological fermentation, pharmaceutical and other process fields. It is used to achieve uniform stirring of the fluid medium and can effectively avoid damage to the cell wall of the cells to be cultured. Background technique: [0002] In the process of some cell culture in the fields of bio-fermentation and pharmaceuticals, it is required to stir the culture medium or other fluid media with a certain frequency and intensity. Most of the agitators currently used are driven by a motor to rotate one or more helical blades to achieve agitation of the culture solution or fluid medium. However, the defect of the original stirring device is that the performance of achieving uniform distribution of oxygen and uniform heating and cooling effects is not good, especially the original stirring paddle such as rotary knife stirring will cause serious damage...

AI Technical Summary

Problems solved by technology

However, the defect of the original stirring device is that the performance of achieving uniform distribution of oxygen and uniform heating and cooling effects is not good, especially the original stirring paddle such as rotary knife stirring will cause serious damage to the cell wall of the cells to be cultivated. Destruction to the point of low cell survival rate or culture failure is also a major factor restricting the development of domestic animal protein production industry
