Milk quality depends primarily on microbial load. Fresh raw milk temperature on milking will be around 37 °C. The milk at this temperature is ideal food for microbial growth which affects its quality and shelf life. Thus, immediate cooling of milk is crucial to control the microbial growth. Milk cooling is practiced through various system which are not feasible to cool small quantity of milk. Major milk production is from millions of small farmers. In this context, the development of suitable and feasible cooling vessel for milk cooling at production is considered. Milk cooling vessel was made from SS 304 series and performance evaluation was carried out using antifreeze solutions. To carry out performance evaluation, 15, 20 and 25 per cent calcium chloride solution; 20 and 25 per cent propylene glycol solution was selected. Optimization of antifreeze solution was based on the rate of cooling.EnglishThesis
