Units

A unit is any vessel that can hold or process materials. Some units have no processing capabilities, such as bulk storage vessels, manual add stations, and hold tanks. Other units have significant processing capabilities, such as reactors, blenders, mixers, dryers, retorts, and washers. Examples of processing capabilities are agitating, mixing, heating, cooling, blending, and packaging. Other examples of units are storage tanks, silos, ovens, fillers, washers, retorts, molders, bottlers, wrappers, cartoners, and palletizers.
