697. All the many kinds of coolers designed for using water 

 require cold water. Some are so arranged that ice may be placed 

 in the water, but this must be stirred as the hot milk warms the 

 water next to the tin. If a constant supply of running water is 

 available, a tank or barrel of water with ice in it may be placed 

 above the cooler and siphoned through the cooler and the tank. 



The Star cooler and others made of rows of coils of pipe are 

 rather expensive, but efficient and satisfactory. If not crowded 

 above their capacity these will cool milk or cream to within a 

 few degrees of the temperature of the water used in the cooler. 



Some of these coolers are so arranged that brine may be 

 pumped through the lower half and a lower temperature than 

 that of the water thus obtained.
