Abstract
This paper deals with milk processing with emphasis on pasteurization. The heat treatment of milk is important in terms of product quality and health safety. The goal of this paper is determination of heat consumption, inactivation effect and Pasteur criterion, by which pasteurization effectiveness is evaluated. The methodical part contains calculations, which were used for estimation of results and description of a pasteurization station used for milk processing. Results obtained in usual working time confirmed that necessary heating and cooling performance were achieved for guarantee of high-quality milk production. Real specific heat consumption was 51.69 kJ/kg. It was achieved by use of regeneration sections in the pasteurizer. These sections allow for a repeated use of 82 % of heat used for heating of raw milk in pasteurization.
