Cyclone bioreactors

Laderach, Widmer, and Einsele, 1978 the cyclone reactor, Dawson, 1974 the cycle tube cyclone reactor, Liepe et al., 1978). The plunging jet reactor developed by Vogelbusch, Vienna, in collaboration with the Engineering Center, Bohlen G., East Germany, is another type of special design that works with a two-phase pump and a foam-like gas/liquid mixture (Schreier, 1975 Steiner et al., 1977). The last type of bioreactor to be mentioned is the thin-film type. Here the liquid and/or solid phase is in the form of a thin layer, and this promotes the reaction. 

No doubt additional effort is needed in the kinetic analysis of a process to optimize a laboratory-scale bioreactor using the criteria listed in Table 4.3. The results, however, should justify the effort. Figure 4.11 illustrates this problem showing that biokinetics seems to be dependent from the type of bioreactor. Productivity is plotted for a stirred tank with increasing rotational speed n and is compared with that in the cycle tube cyclone reactor (Ringpfeil, 1980).
