Continuous methods in fermentation industry.Peer-reviewed article
J. DYR
Kvasny Prum. 1961; 7(2): 25-30 | DOI: 10.18832/kp1961005 
The article deals with some problems of continuous fermenting processes and conditions for their application in various branches of fermentation industry. The author explains the characteristic features of typical processes and differences between them. Some of them are aimed at obtaining maximum amount of metabolite, this being the case of distilleries, the results of others is production of biologic substance, as it is in yeast plants. Several other fermenting processes are briefly mentioned, as e.g. production of vinegar, glycerine, organic acids etc. Much attention is paid to continuous brewing. The author underlines the complexity of problem,...
Manufacturing yeast albumins without waste water.Peer-reviewed article

Kvasny Prum. 1961; 7(2): 31-32 | DOI: 10.18832/kp1961006
The article deals with a new technology of producing feed yeast, the main feature of which is elimination of waste water. The main difference, as compared with orthodox technology, is in returning fermented mash after centrifuging back into technologic cycle, instead of diluting it with water. After the desired concentration of dry matter has been achieved the recirculating mash is condensed in a multi-stage evaporator. The product can be further treated is the same way as molasses residues at distilleries processing molasses, through far better ways may be soon introduced. The described method has been successfully introduced by several plants and...
Effect of agitation on oxygen transfer in yeast production.Peer-reviewed article

The article presents the results of experiments aimed at improving the technology of yeast production by introducing agitation synchronized with aeration. The authors have measured the oxygen consumption in the course of fermentation and studied the influence of water temperature, height of liquid column undergoing aeration, number of agitator revolutions etc. Their conclusions indicate, that by synchronous agitation and aeration very substantial savings can be achieved, as the amount of air can be reduced by as much as 50 %. Further savings result from reduced consumption of defoaming substances and other chemicals.(In Slovak, English summary only)
Combined evaporators of waste water at torula plants.Peer-reviewed article
V. SÁZAVSKÝ
Kvasny Prum. 1961; 7(2): 36-37 | DOI: 10.18832/kp1961008
To reduce the steam consumption necessary for treating waste water at torula plants the author suggests to combine evaporators with torula drying drums. The scheme is based upon detailed calculations indicating its advantages, though some difficulties must be taken in the picture, too.(In Czech, English summary only)
Intensifying fermentation by introducing mould activators.Peer-reviewed article
J. KOLEK
Kvasny Prum. 1961; 7(2): 37-38 | DOI: 10.18832/kp1961009
The article deals with the results of experiments aimed at determining the possibilities of intensified fermentation of fruit wine by introducing into it mould activators prepared from the mycellium of the mould fungus Aspergillus nige. This mycellium is obtained from the waste products of plants manufacturing citric acid by fermentation. The fermentation of wine with mould activator added was faster and alcohol content higher. Since the quality of wine was better, the author recommends to introduce the method on a large scale.(In Czech, English summary only)
