| Abstract: | Engineering aspects of solid state processes, design of fermentors, control systems for maintaining parameters are important problems for the research in this area. Laboratory scale reactors (2 kg dry-matter capacity) were constructed to allow control of the temperature and moisture level of the substrate without agitation. Forced aeration is accomplished by means of thermostated air injected at the bottom of the reactor. By bubbling in a waterbath and after heating, the thermostated air allows the regulation of temperature and moisture content of the medium during the cultivation. These reactors have been used for the study of protein enrichment of leached sugar-beet pulp by solid state processes. |
