Description

Technical Field

[0001] The utility model relates to supporting equipment for a bioreactor, in particular to a supporting device for a disposable bioreactor. Background Art

[0002] In the production and manufacturing process of biological products, the use of bioreactors is indispensable. Generally, bioreactors are divided into reusable and disposable systems. Reusable bioreactors are generally divided into small and micro glass bioreactors used in product development and process optimization and stainless steel bioreactors used in pilot and large-scale production. Reusable bioreactors need to be fully sterilized before use, and the reactor system needs to be cleaned after batch culture. Especially in the production and development of food and drugs, strict cleaning verification of equipment cleaning is required, which is time-consuming and labor-intensive. This method of sterilizing the reactor before use and cleaning and verification after use not only increases a lot of labor costs, but also prolongs the entire product development cycle, so it is not necessarily cost-effective to calculate the cost as a whole.

[0003] There are many disposable bioreactors on the market, such as disposable oscillating cell bags for cell culture. Due to the limitation of their mass transfer method, their cell density is difficult to compare with that of stirred bioreactors. In addition, this structure is also difficult to achieve scale-up production. There are also bag-type disposable stirred bioreactors, which are limited by their structural pressure tolerance and ventilation mode, and their mass transfer performance is not very good, and cannot meet the cultivation needs of cells / microorganisms with high oxygen demand.

[0004] Therefore, developing a support device for a disposable bioreactor has become an urgent problem to be solved by those skilled in the art. Summary of the invention

[0014] Furthermore, a pipeline bracket is connected to the stirring connection bridge reinforcement plate through a pipeline bracket fixing piece, and an exhaust gas filter bracket is installed on the left stirring connection bridge and the right stirring connection bridge through screws. The exhaust gas filter bracket can float up and down with the stirring motor, and can also move left and right through screws.
