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 be 
‘apacity 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 smail 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.

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).

Sanitary milk piping and fittings. 
Belting, shafting, pulleys, hangers, ete. 
A supply of bottles, caps, washing powder, coal, ete. 
(2) Equipment for medium-sized plants (250 to 1,000 gallons) : 
5-beam platform scale or a dial scale.
