It stands to reason that any and all of these ice coolers 

 are not doing their best work unless there is some provision 

 for stirring or moving the iced water, and while they may 

 be used with water alone, they will be less effective, and it 

 may be laid down as a rule that ice or a refrigerator machine 

 is a necessity if pasteurizing is to be successful, unless indeed 

 a flowing well of 48 or less is available.
