METHOD AND APPARATUS FOR PNEUMATIC CONVEYING ARTICLES

摘要

Live chickens are conveyed through a conduit including a suction intake section connected to a pressure discharge section by an intermediate section having an air suction port, a pivotable door, and an air pressure port within each end portion. Air is alternately sucked through the suction ports and is alternately blown through the pressure ports by operation of a valve system actuated in response to a device which sense the presence of each chicken within the conduit. The pressure within the discharge conduit section is sensed for controlling the flow rate of the air blown through the discharge section to assure that the chickens flow at a substantially uniform rate through the duct.
