Variable milk sampling device - has Pitot tube in flow line with throttle piston movable into tube end to control sample size

摘要

Variable sampling device of partial quantities from milk line prevents adjustment of Pitot nozzle during acceptance process. For the examination of a partial quantity, milk is passed through a delivery tube to a sample container. During the acceptance process the delivery tube is blocked in a predetermined position of the throttle. It is not released until the acceptance process has been completed. The delivery outlet (6) is brought to the predetermined position of the throttle by means of a throttle piston (1) via interchangeable adjusting pieces (3, 4). During the acceptance process the adjusting pieces (3, 4) are blocked and released later.
