Electric Dairy Cold Storage

given to lis and dcliverefl at our door, we could hardly handle it to 

 the cold storage for what our daily electric cost is for the sanie job." 



The third owner's conclusion is, "I wovdd not consider disposing of 

 such equipment on any grounds." 



On Farm No. 1 the ice method was develojied with considerably less 

 innnediate outlay than the electric, and this may be quite a factor 

 with some farmers. If the latter is arranged for on a time payment 

 basis, it may be a point of less consequence. 



Summary. Table 14 summarizes the results of the two methods as 

 used on a total cost basis, in units of cubic feet of storage and total 

 contents, 100 cjts. of milk for a year or the period the machine was 

 run, and per cow per year. Maximum and minimum values are given 

 followed by the average in bold type. 



With the values used and this method of computing the results the 

 electric method effects an economy in obtaining refrigeration, as com- 

 pared to ice, of a considerable amount. From this it appears that when 

 operating with ice the range in costs varied from 45% to 156% more 

 than with the electric method. Ice ran from 79% to 98% with an av- 

 erage of 91% more cost per cu. ft. of either total or storage contents, 

 94% to 112% more per 100 qts. of milk averaging 98% for the year or 

 103% more for the time the machine was run, and 100% more per cow 

 per year and in total expense. Results obtained will vary with differ- 

 ent values which may be placed on farm labor by different farmers, and 

 this is the imi)ortant point in arriving at a result for any given case. 

 With the percentages noted it would appear, however, that electric re- 

 frigeration should be practical and successful on many farms of the 

 business-like type already referred to. 



Ficj. 14. A cliore now eliminated where the electric dairy cold 

 storage ha^ been installed. An ingenious labor saving arrange- 

 ment to facilitate the getting in of ice on one of the test 

 farms before the advent of electricity.
