Abstrakt

Issues of the accurate measurement of heat transfer coefficient for packed bed of vegetables is complicated due to their complex geometry and the necessity to use speed as well as non-invasive method. The paper presents the basis of innovative approach of the measurement of the average heat transfer coefficient using the single blow method for the case of the packed bed of vegetables. The presented results cover heat transfer coefficient measured for carrot stored in packed beds for two various arrangements under conditions of various turbulent intensity at the inlet to the bed from 2 up to 14%. The dimensionless heat transfer correlations were proposed on the basis of the obtained results. It was demonstrated that due to flow laminarisation inside the bed the turbulence intensity has no significant effect on heat transfer inside the bed.
