HEAT FLUXES AND OPTIMAL THICKNESSES OF WALL INSULATION OF INCUBATION CHAMBERS OF THE DAIRIES.

Author(s) : DJAKOVIC B.

Summary

IN AN INCUBATION CHAMBER, YOGURT IS MAINTAINED 2 TO 3 HRS AT AN ALMOST CONSTANT TEMPERATURE, 315 K (42 DEG C), THEN IT IS COOLED TO ABOUT 288 K (15 DEG C) WITHIN 40 TO 60 MIN. HEAT FLUX VARIATIONS ARE DUE TO CHANGES IN TEMPERATURE DISTRIBUTION IN TRANSIENT STATE. THIS STUDY GIVES MATHEMATICAL EXPRESSIONS OF TEMPERATURE GRADIENTS AND HEAT FLUXES DURING HEATING TIMES. THESE EXPRESSIONS MADE IT POSSIBLE TO DETERMINE THE OPTIMUM INSULANT THICKNESS REQUIRED FOR INCUBATION CHAMBERS, WITH CONSIDERABLE SAVINGS. THE GRAPHICAL SOLUTION OF A SPECIFIC CASE GIVES THE OPTIMUM POLYURETHANE THICKNESS.
