Notes:
A static heat exchanger was used to study the extent of heat induced fouling in the device due to passage of cow, buffalo, double toned and reconstituted milk for a period of one hour. The static heat exchanger was developed to simulate the flow condition of an actual indirect type heat exchanger employed in the processing plant. Flow rate of 2x10-7 m3 s-1 was selected as this gave the same 1.052x10-3 m3 m-2 flow rate/surface area ratio as applicable to indirect double tube heat exchangers used in the industry. Both milk with fat and with fat removed by centrifugal separation were used. Fresh and recycled milk were the other two factors used in the study of fouling. It was found that there was no significant difference in fouling deposit formation between fresh and recycled milk, but significant difference existed between milk with fat and milk with fat removed. Reconstituted milk was found to have significantly lower deposit compared to cow, buffalo and double toned milk.
