HEAT RECOVERY IN FARM MILK TANKS.

RECUPERATION DE CHALEUR SUR TANK A LAIT.

Type of article: Article

Summary

A SERIES OF TESTS WERE CARRIED OUT ON A REFRIGERATED FARM MILK TANK (1,200 L CAPACITY, COOLED BY DIRECT EXPANSION) PROVIDED WITH A HEAT-RECOVERY UNIT. MEASUREMENTS WERE MADE OF THE MAJOR OPERATIONAL PARAMETERS, INCLUDING ENERGY CONSUMPTION OF THE COMPRESSOR AND OF CONDENSER FAN, TEMP. OF THE MILK AND OF WATER HEATED IN THE RECOVERY UNIT, ENERGY RECOVERED, AND MILK COOLING TIMES. THE RESULTS ARE PRESENTED IN TABLES AND GRAPHS. MAJOR FINDINGS WERE THAT THE USE OF THE HEAT-RECOVERY UNIT HAD LITTLE EFFECT ON THE DURATION OF MILK REFRIGERATION, ENERGY CONSUMPTION BY THE COMPRESSOR AND ELECTRICITY REQUIREMENTS FOR THE COOLING OF THE MILK. THE AMOUNT OF ENERGY RECOVERED DURING COOLING OF THE MILK FROM THE FIRST AND SECOND MILKING WAS ABOUT 7-8 KWH, THIS BEING ONLY SLIGHTLY DIFFERENT FROM THE AMOUNT OF ENERGY ABSORBED BY THE COMPRESSOR AND THE FAN OF THE REFRIGERATION PLANT. THE AV. WATER TEMP. WAS ABOUT 323 K (50.C), BUT IT IS (DAIRY SCI. ABSTR., GB., N.10, 1980, 728, 6237.).
