Abstract
An apparatus and method for measuring predetermined amounts of liquid additives, such as a detergent, acid, and/or a sanitizer which may then be automatically dispensed during a cleaning cycle of the dairy pipeline cleansing system. The apparatus includes metering chambers for each of the liquid additives which are connected by a supply line to respective bulk containers. A vacuum source is connected to the metering chambers through an intermediate trap chamber. A valve assembly is provided within each of the metering chambers to block off the vacuum source once the chambers are filled to the desired level. Valves are provided in each of the metering chambers for dumping the respective liquid additive into the cleaning system tank at a selected time.
