Özet

A heat pump system based on the liquid-to-liquid principle was designed in order both to heat to the pasteurization temperature (at 69-degrees-C) and cool to the inoculation temperature (at 32-degrees-C). The quantities of energy needed for the pasteurization and inoculation cycles for both the present system and the classical system were experimentally obtained and compared with the quantities of energy used. Some experiments were carried out to define how microbiological and chemical properties of milk changed during the pasteurization and inoculation cycle. The present results were compared with the properties of milk pasteurized in the classical system.
