INVESTIGATION OF HEAT TRANSFER CONDITIONS IN SCRAPED SURFACE HEAT EXCHANGER

Scraped surface heat exchangers are widely used in the food industry and in the developing aseptic technology to guarantee products of high quality. In the literature review the flow and heat transfer conditions of these heat exchangers are analysed. An experimental station supplied with data acquisition system has been built, which makes possible to vary testing parameters. Heat transfer equations required for dimensioning scraped surface heat exchangers were determined at different operational parameters
