Efficient and versatile design of a tray type solid state fermentation bioreactor

Fermenteur industriel à plateaux pour les cultures en milieu solide

  • Chapter
Advances in Solid State Fermentation

Summary

The most popular type of bioreactor, industrially used for solid state fermentation (SSF), is the static tray system. It is essential that oxygen availability is ensured at all points in the substrate bed and heat generated can be removed efficiently, simultaneously with control of water activity at desired level, irrespective of the conditions in the external atmosphere. This requires a careful design of the bioreactor. This paper deals with the development of a versatile design of an industrial tray-type SSF bioreactor, with a number of desirable features, such as efficient mixing and uniform circulation of filtered air, control of relative humidity and temperature under varying external atmospheric conditions.

Resume

Le bioreacteur le plus communément utilisé en industrie pour les fermentations en milieu solide est le fermenteur statique de type “à plateaux”. Au cours des FMS, il est indispensable que l’oxygène soit disponible en tout point du milieu de culture et que la chaleur produite soit évacuée. De même, l’activité de l’eau doit être contrôlée à chaque niveau du bioréacteur, quelques soient les conditions atmosphériques externes. La conception d’un bioréacteur doit donc tenir compte de ces problèmes particuliers. Cet article présente la mise au point d’un fermenteur industriel FMS adaptable de type “à plateaux “. Il dispose d’un dispositif d’homogénéisation du milieu, permet la circulation uniforme de l’air filtré, un contrôle de l’humidité relative et de la température pour différentes conditions atmosphèriques externes, etc.
