Gallon size cans recpiire about one degree F. more heat on a 15 minute run of holding than tall-size cans, and tall-size cans require about one degree F. more than family- and baby-size cans. The installation and efficient use of automatic temperature controllers and recorders is of material assistance for securing uniform results of sterilization. These accessories are made use of in numerous factories, and have pro\en to be of valuable help to the manufacturer. Aside from the fact that they actu- ally do facilitate the temperature control, they automaticallv. Tig. 63.

The knowledge of the operator that his work is permanenth- recorded and checked up exerts a beneficial efl:ect on liis performance. The operation of an experimental or pilot sterilizer also has proven a great lielp in the accurate determiiiation of the amount of heat which the exaporated milk of an\- liatch requires, to produce the desired viscosity, body and color and that it will stand without becoming curdx-.
