Example Embodiment

[0020] Example 1:

[0021] The packed bed cell bioreactor without stirring device includes: a reaction tank body 110, the reaction tank body is connected to the shaker 50 through an eccentric shaking plate 58, and the shaker shakes the eccentric shaking plate to make the reaction tank body Rotate eccentrically. The upper part of the reaction tank body 110 is a circular truncated shape 100, and the lower part is a cylindrical shape 113. The upper part of the truncated truncated shape is equipped with a guide pipe 130, and the inlet 131 of the guide pipe is close to the reaction tank tank. The inner wall of the body, the outlet 133 of the guide pipe enters the central funnel 160 along the tangential direction of the central funnel, and the reaction tank body has a tank with an air inlet, an air outlet, a liquid inlet, and a liquid outlet. The lid 140 has a packed bed 120 inside the reaction tank.

Example Embodiment

[0022] Example 2:

[0023] In the packed bed cell bioreactor without stirring device according to Example 1, the packed bed includes an upper orifice plate 125 , a lower orifice plate 122 and an empty casing 124 . The inner wall of the inner cylinder 113 of the reaction tank body 110 is connected to the lower orifice plate 122 and the empty casing 124, the upper end of the empty casing 124 is connected to the upper orifice plate 125, the upper orifice plate 125, the empty casing 124 The lower orifice plate 122 constitutes a packed bed 120, and the sheet-like microcarriers 26 are filled between the lower orifice plate and the upper orifice plate. The packed bed 120 is consistent with the centerline of the reaction tank body 110 . The reaction tank has a base 114, the reaction tank 110 and the shaking plate 58 are connected through the base 114, and the reaction tank body 110 and the tank cover 140 are connected by bolts.

Abstract

The invention discloses a packed bed type cell bioreactor without a stirrer and a method for cultivating animal cells. To meet the requirements for large-scaled high-density animal cell cultivation, the cell bioreactor is required to amplify and strengthen functions thereof. The packed bed type cell bioreactor without the stirrer consists of a reactor body (110), wherein the reactor body is connected with a shaker (50) through an eccentric wobble plate (58); and the shaker shakes the eccentric wobble plate to make the reactor body rotate eccentrically. The upper part of the reactor body is shaped as a round table (100), and the lower part of the reactor body is a cylinder (113); a flow guide tube (130) is arranged on the upper part of the round table, an inlet (131) of the flow guide tubeis close to the inner wall of the reactor body, an outlet (133) of the round table enters a central hopper (160) along the tangential direction of the central hopper; the reactor body has a reactor lid (140) with an air inlet, an air outlet, a liquid inlet and a liquid outlet; and a packed bed (120) is arranged in the reactor body (120). The packed bed type cell bioreactor without the stirrer provides a good environment for cell cultivation.

Description

Technical field: [0001] The invention relates to a cell bioreactor, in particular to a method for cultivating animal cells in a packed bed cell reactor without a mechanical stirring device for culturing animal cells. Background technique: [0002] At present, the world's biotechnology pharmaceutical industry is developing rapidly and has made great achievements. The expression and production of various diagnostic and therapeutic monoclonal antibodies, vaccines, growth factors and other biologically active proteins through in vitro culture of animal cells has a very broad market application prospect. Therefore, cell bioreactors used for large-scale high-density cultivation of animal cells have become the most important equipment in the biotechnology pharmaceutical industry. It largely determines the product cost, production scale and product category of biotechnology pharmaceutical companies. The existing reactor adopts mechanical agitation inserted into the tank. The struc...
