PROFITS FROM MANUFACTURE OF ICE CREAM 2OQ 



of disadvantage, for the reason that homogenized cream cannot 

 be churned. 



A. Its Value in Ice Cream Making. In ice cream making 

 this treatment of the cream has the advantages that the cream 

 acquires a firmer and smoother body so that a 20 per cent 

 homogenized cream will produce an ice cream of a similar 

 consistency as ice cream made from a richer cream. Ice cream 

 made from homogenized cream possesses better keeping quali- 

 ties and will yield more services per gallon than that made 

 from cream which has not been so treated. It is furthermore 

 entirely free from butter particles which are so readily formed 

 in untreated cream during the process of freezing. 



Since the introduction of the homogenizer it has been learned 

 that by heating skim milk to a high temperature and then add- 

 ing melted butter in definite quantities and homogenizing, it is 

 possible to produce a cream which in appearance is identical 

 with normal cream. This system has the disadvantages: First, 

 that it discourages the production of sweet cream, which 

 means much to the dairy states, as it is well known that the 

 ice cream manufacturer is recognized to be the principal edu- 

 cator for quality; second, it discriminates against the smaller 

 ice cream manufacturer, as he cannot afford to install a homog- 

 enizer and is therefore compelled to buy more expensive cream; 

 and third, if butter from sour cream is used then it becomes 

 nothing less than a renovating process. 



The production of artificial cream in places where dairying 

 is not well enough developed should not be discouraged, for if 

 the cream has to be shipped a great distance it is more economi- 

 cal and fully as sanitary to produce the cream from butter made 

 from sweet cream, from a practically sterilized milk powder, and 

 from sterilized water. 



B. Cost of Homogenization. The machine after it has 

 been started requires but little attention. One man's time 

 while the homogenizer is operated is sufficient. In addition to 

 that the main cost is the cost of power and the interest on the 

 investment. A homogenizer of sixty gallons' capacity per hour 

 requires 3 horse power, By installing a larger homogenizer
