Notizen:
Calculations have been made with the aim of utilizing the waste heat released at constant rates in the large-scale production of fooder yeast in the G.D.R. and as yet unused, for thermally concentration of fermentation products. The following results were obtained, based on left-handded thermodynamic cycles and corresponding with the largest production plants working in the G.D.R.There is the prospect of integrated heat pump systems with direct exposure of evaporator and condenser surfaces and steam-driven compressors supersending conventional, steam-heated concentration systems. There is, however, a major hazard in the form of possible breakthroughs of refrigerants into the biosuspension. Processes involving what is known as vaporization cooling and operating without specific refrigeration cycles can presently not compete with conventional systems.None of the two versions can make full use of the waste heat from fermenters for thermal processing. Recovering between 20 and 30% would be an economical proposition.
