Problems solved by technology

[0003] The purpose of the present invention is to provide an improved bioreactor. By setting up an improved liquid feeding pipeline, the method of adding liquid attached to the wall is realized, which solves the problem that the tank top is directly connected to the bottom of the tank in the prior art. There are dead corners inside the tank when the liquid is added to the liquid pipe, residual liquid in the liquid pipe, difficult installation of the pipe, and damage to the cells.

Embodiment Construction

[0009] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0010] In the prior art, the liquid feeding pipeline of the improved bioreactor usually uses a pipe directly extending from the top of the tank to the bottom of the tank. Such a structure will cause many bubbles to cause damage to the cells when adding liquid. It will cause problems such as cleaning dead ends, residual liquid remaining in the pipeline, and installation difficulties.

[0011] The improved bioreactor of the invention can realize the way of adding liquid adhered to the wall and reduce the generation of air bubbles when adding liquid. See figure 1 , the improved bioreactor of the present invention includes a tank body 2 and a liquid-feeding pipeline 1, wherein the liquid-feeding pipeline 1 is fixed on ...

Abstract

An improved bioreactor comprises a tank body and a liquid adding pipeline. The liquid adding pipeline is fixed on the upper portion of the tank body, a liquid inlet of the liquid adding pipeline stretches out of the tank body, and a liquid outlet of the liquid adding pipeline is located in the tank body and faces the inner wall of the tank body; two heating modules are symmetrically arranged in the tank body, the tank body is arranged in a base, and the lower portion of the base is provided with wheels. According to the improved bioreactor, culture liquid can flow to the bottom of the tank body along the inner wall of the tank body when the liquid is added, and therefore bubble generation is effectively reduced; in addition, moving is convenient.

Description

technical field [0001] The invention relates to an improved bioreactor and belongs to the field of biotechnology. Background technique [0002] The liquid feeding pipeline of the bioreactor is used to supplement the culture medium, inoculate cells, etc. into the tank of the bioreactor. The volume of cell culture medium or inoculated cell suspension required in large bioreactors is large, so it is necessary to use pipelines with large inner diameters such as DN25 or DN40. The liquid feeding pipeline of the traditional bioreactor usually uses a pipe directly from the top of the tank to the bottom of the tank. If this traditional liquid feeding method is followed, there may be the following problems: 1) The inside of the tank will increase the amount of dirt that is difficult to clean. 2) After adding liquid, some residual liquid may remain inside the liquid feeding pipe to form a dead area, which cannot effectively fuse with the cells outside the liquid feeding pipe; 3) Due t...
