In SSF, the bioreactor provides suitable environment for microorganism growth and biological activity. Bioreactors must be able to hold the media and be sealed well which prevents harmful environment substances entering in to the bioreactor. Important parameters in bioreactor design include temperature, oxygen concentration, moisture gradients as well as mixing/agitation, aeration and heat transfer. SSF bioreactor design can be classified into four groups, which can be separated by aeration and mixing type: | |||
==== Tray bioreactor ==== | * Group 1: unforced aeration, without mixing/agitation (static) | ||
* Group 2: forced aeration, without mixing (static) | |||
* Group 3: unforced aeration, with continuous or intermittent mixing/agitation | |||
* Group 4: forced aeration, with continuous or intermittent mixing/agitation | |||
==== Group 1: Tray bioreactor ==== | |||
"Tray bioreactors consist of a chamber containing individual trays that can be made of different materials, such as wood, bamboo, metal, and plastic. The trays typically have open tops and perforated bottoms, and are stacked one above another with a space in between to increase the availability of air. The trays are static beds that are mixed infrequently or not at all. Air is provided into the chamber and circulated around the trays with controlled humidity and temperature."<ref name=":2">{{Cite book|author=X. Ge, J. Vasco-Correa, Y.
