Still machine setters set up, operate or tend continuous flow or vat-type equipment; filter presses; shaker screens; centrifuges; condenser tubes; precipitating, fermenting or evaporating tanks; scrubbing towers; or batch stills. These machines extract, sort or separate liquids, gases or solids from other materials to recover a refined product. Within this category, this report looks at dairy processing equipment operators only.
Three states require a license to work as a dairy equipment still machine setter: California, Oregon and Washington. California and Oregon both require two exams, while Washington requires none. Oregon also sets a minimum age of 18 years. None of the states requires any education or experience. The three states require an average of $67 in fees. These requirements are the 89th most burdensome of the 102 occupations studied here. Also, because so few states license the occupation, it ranks as the 92nd most widely and onerously licensed.
