MILK SURVEY OF THE CITY OF ROCHESTER 



The dealers who were cooling milk only did not all of them report cool- 

 ing charges. The number reporting cooling charges were handling 33,266 

 quarts with 118 men employed for a total of 64.3 man hours at the rate 

 of 517 quarts per man hour, at a cost per quart of .000790. These figures 

 are tabulated in Table No. 56. 



TABLE NO. 56 

 PASTEURIZING AND COOLING 



If we apply these figures to the volume of milk mentioned at the 

 Rochester rate of .50 per man hour, the present cost for companies both 

 pasteurizing and cooling amounts to $14,541.60 per year, and for the 

 companies cooling only $9,595.85 per year, or a total of $24,137.45 per 

 year for the quantity of milk reported. Under a centralized system milk 

 can be pasteurized by large sized machinery. The manufacturing com- 

 panies many of them build machines capable of pasteurizing 12,000 Ibs. 

 of milk per hour, which is at the rate of more than 5,500 quarts per 

 hour. 



It will be noted in the table that one large company handling 64,800 

 quarts daily pasteurizes at the rate of 6,480 quarts per hour. Assuming 

 under a centralized system that Rochester could pasteurize milk with ap- 

 paratus which would handle 5,500 quarts per hour the cost would be 

 .000091 per quart, or $2,723.40 per year. In presenting these figures it is 

 necessary to bear in mind that in the tabulation above only 47,373 quarts
