Description:

The purpose of the bioreactor in a microbiological process is the establishment of optimal conditions for the life it cultivated cells or microorganisms. In the bioreactor occurs microbiological synthesis, enzymatic processes, and also cultivates a culture of cells or micro-organisms. In biotechnology bioreactor is one of the Central links of the main technological process.

The bioreactor is a heterogeneous system of components, consisting of a suspension of cells, and gas. In such a system needs to be ways of transferring heat and mass between the phases with the aim of creating optimal conditions for the growth of producer and biosynthesis of the target product, under the conditions of sterility and efficiency of the process.

A method of transferring heat and mass between environments largely determines the type of the bioreactor and, ultimately, the cost of the final product. Gas-vortex bioreactors in efficiency significantly superior to other types of existing bioreactors.

Gas-vortex bioreactors is different from conventional machines by the fact that the mixing is realized with swirl (without the “stirrer” in the fluid), due to the differential pressure above the liquid surface and friction of the air flow about its surface.

As a result, in a liquid medium creates a well-organized three-dimensional movement with a vertical component. The absence of a “stirrer” in the fluid provides energy, gentle but very effective 3D-mixing of fluids, including viscous, without foaming, water hammers, cavitation, high turbulent, stagnant zones and micro-watersheds with a high temperature.

Using universal gas-vortex bioreactors, it is possible to quickly move production from one type of producer strain to another. The company may, without large costs to respond quickly to the latest developments in the field of biotechnology and to modify or expand the range of products.

In the implementation of many laboratory developments in manufacturing there is a problem with the scaling of the result – the impossibility of reproducing in an industrial scale laboratory process. Often, especially for sensitive cells (hybrid, embryonic, etc.), to play it extremely difficult, and sometimes impossible. A substantial part of promising developments and remains not implemented due to the impossibility to reproduce the obtained results with increasing volumes of cultivation. This is due to the fact that the hydrodynamics of the mixing process when zooming in the existing types of bioreactors significantly varies with increase of the apparatus. Due to the vortex mixing mode no such problems.

 


Advantages:

– high efficiency,

is a versatile equipment used in microbiological processes

– provides a gentle but very effective 3D-mixing of fluids

has a high rate of mass transfer across the phase interface, which ensures the absence of problems of cell damage by bubbles of air,

– low power consumption – 0.1 W/l, which is significantly less than that of bioreactors with mechanical agitators, that determines the prospects of its use in largescale production,

works without changing its characteristics when filling 10 to 90% by volume, which allows the industrial production of clean intermediate “executable” bioreactors,

– ensures good mixing of viscous liquids and liquids with changes in process viscosity

gas vortex is an effective antifoam,

– hydrodynamics of the bioreactor depends little on the level of the liquid therein, the bioreactor is easy scales,

the possibility of the successful cultivation of virtually all cell types (including sensitive and stem) and microorganisms

full reproducibility (scalability) of laboratory results in industrial application,

reducing the number of procurement of laboratory bioreactors with a single universal gas-vortex bioreactor instead of a few highly specialized types of cells and microorganisms

the exception, of chemical antifoam essentially complicated and high cost further purification process and the final product,

simplification and reduction scheme communication pipelines

– reduction in total production costs (electricity, water, steam, detergents, squares, payroll),

reduce consumption of resources (water, electricity, etc.) and reduce waste,

– financial stability of the enterprise due to the possibility of quick and low-cost changes or expansion of product range,

significant reduction in the cost of production.
