FIG. 40. Continuous Ice Cream Freezer. The cream flows 

 into the first compartment from the supply tank and com- 

 ing in contact with the cold disks, in which brine solution is 

 circulating, at once commences to freeze. As the disks re- 

 volve the cream is kept agitated. The metal fingers sus- 

 pended between the disks prevent the cream from freezing 

 on. From the first compartment the partially frozen mix- 

 ture overflows into the second. The latter compartment is 

 deeper than the first, and contains in addition to the freez- 

 ing disks a revolving screw which carries away the cream 

 as fast as the freezing is completed. This conveyor extends 

 about 18 inches from the freezer and discharges into the 

 packing can.
