(under the class definition) Device including means to raise or lower the temperature of milk products or closely allied animal products, such as lard, shortening, etc. to such a degree that a significant change is produced (e.g.
sterilization or pasteurization, etc.), means to subject such food to a gaseous treatment, or means to provide for a food manipulating treatment that changes the character of the food (e.g. separating, coagulating, etc.).
(1) Note. The foodstuffs that are prepared and treated are predominantly those commonly known as "dairy" foods, including milk, butter, cheese and other products derived from the mammary fluid of domestic animals.
