for 30 minutes. It is important that equipment of ample capacity to 

 handle the maximum output of the plant be selected. However, the 

 pasteurizers should not be so large that they will wear out and de- 

 preciate before the business is developed to the point that large- 

 capacity equipment is required. 



For small plants the work must be so arranged that men can be 

 shifted from one kind of work to another, while in larger plants more 

 specialization in the plant operations can be maintained. For this 

 reason the equipment in small plants must be large enough to permit 

 the pasteurizing and bottling to be done in from two to four hours, 

 leaving the remainder of the day for other work. 



LISTS OF EQUIPMENT. 



Below are lists of the principal equipment required for milk plants, 

 grouped as follows: (1) Small plants, less than 250 gallons daily; 

 (2) medium-sized plants, 250 to 1,000 gallons daily; and (3) large 

 plants, over 1,000 gallons daily. 



(1) Equipment for small plants (less than 250 gallons) : 



Platform scale (double beam). 



Temperature recorder. 



Pasteurizing vat (100 to 300 gallons capacity). 



Tubular cooler (if milk is cooled in the vat, cooler may be eliminated). 



Small bottle filler ,( a filler designed to fill four bottles at a time is satis- 

 factory). 



Bottle washer (consisting of a turbine brush with rinser and steamer). 



Bottle cases (about two sets of cases will be required). 



Cans (cans for delivery of milk to wholesale trade; farmers should pro- 

 vide cans for bringing the milk to the plant). 



10 to 15 horsepower boiler. 



3 to 5 horsepo^Yer motor. 



Brine tank. 



Can wash sink with steam jet. 



Small separator (about 2,000 poimds per hour). 



Small churn (100 pounds butter capacity). 



Milk storage room (a room of about 6 by 8 feet provides enough space 

 to store one day's supply of bottled milk). 



Babcock tester (12-bottle size). 



Steam and water hose with fittings. 



Steam and water piping. 



Milk pump (if gravity is used no pump is required). 



Sanitary milk piping and fittings. 



Belting, shafting, pulleys, hangers, etc. 



A supply of bottles, caps, washing powder, coal, etc. 



(2) Equipment for medium-sized plants (250 to 1,000 gallons) : 



5-beam platform scale or a dial scale. 

 2-compartment weigh can. 

 Receiving vat (200 to 400 gallons capacity). 

 Sanitary milk pump (capacity 6,000 pounds per hour).
