MILK SURVEY OF THE CITY OF ROCHESTER

TABLE NO. 55 

 APPARATUS WASHING 



From Table No. 55 it appears that the present Rochester costs are 

 .000680 per quart, or a daily cost of $20,359.70. An inspection of the 

 number of quarts per man hour for which the apparatus is washed in 

 these different companies shows four companies with over 1,200 quarts 

 per man hour, and one of these with over 3,000 quarts per man hour. If 

 we assume that 2,000 quarts per man hour is a fair estimate for effective 

 washing of apparatus, this would be only % of the efficiency of the best 

 company, and but 40% more than the efficiency" of 2 others in the list. 

 If we apply the Rochester wage scale for apparatus washing of .427 to 

 2,000 quarts per man hour, the cost per quart for washing apparatus 

 under a centralized system would be .000213, and a yearly cost for the 

 entire Rochester milk supply of $6,395.90. This would effect a saving of 

 .000467 per quart, and $13,963.80 per year. 



PASTEURIZING AND COOLING 



The figures for pasteurizing and cooling for Rochester must be 

 divided into two parts, for the reason that while many of the large dealers 

 operate both pasteurizing machines and milk coolers, the majority of 

 small dealers do not operate pasteurizers, but only operate a cooling ap- 

 paratus, consequently in presenting these figures we have listed separately 

 the figures for those dealers who operate both pasteurizers and coolers 

 and those who operate only coolers. The volume of milk which is pas- 

 teurized and cooled was 47,373 quarts daily, and by these dealers there 

 were employed 37 men for 79.7 man hours who pasteurized and cooled 

 milk at the rate of 594.4 quarts per hour at a cost of .000841 per quart.
