Kvasny Prum. 1969; 15(2): 29-33 | DOI: 10.18832/kp1969004 
The situation in the bottling rooms in the majority of the food industry plants is far from being satisfactory, as the noise level is there extremely high. The author suggests some measures which can reduce it, as e. g. usage of containers made of plastics, modifications in the construction of some machines, installation of sound damping screens etc.(In Czech, English summary only)

The efficiency of sedimentation in a 300 hl whirlpool tanks has been studied to ascertain the settling of sludge on the bottom of the tank and relation between the flow velocity of incoming wort, consistency of sludge and clarification efficiency. The tank was fitted with cocks for taking samples from various points of the tank. The following criteria were applied to evaluate the process: clarity of wort, sludge separation rate (for coarse sludge) and losses of extract in settled sludge. To obtain satisfactory clarity the sedimentation process must last 40 minutes. Gradual settling continues some 60 minutes more. The intake velocity was controlled...
Phenolic substances in barley.Peer-reviewed article
M. ČERVINKA
Kvasny Prum. 1969; 15(2): 38-40 | DOI: 10.18832/kp1969006
Taking as a base reports published abroad in literature the author has developed a new method for the determination of derivatives of benzoic and cinnamic acids in barley. The method permits to study the metabolism of the mentioned compounds in the final stages of the barley vegetative cycle, expecially their concentration in corns. The participation of phenolic substances in non - biological turbidity of beer can be also reliably assessed by panlying the discussed method.Taking as a base reports published abroad in literature the author has developed a new method for the determination of derivatives of benzoic and cinnamic acids in barley.
