To solve problems in which there is a possibility that granules are clogged in a halfway part of a transfer passage to a discharge port and granules are not transferred to the discharge port when pressure air fed to a pipe is weak and there is a possibility that granules are not fed to the discharge port in adequate state, because granules are reversely made to flow to a feed out port of a granule feed-out part and are not smoothly transferred or granules are vigorously made to collide with each other in the transfer passage to the discharge port and are deformed or granules are discharged in excessively struck state when pressure air fed to the pipe is too strong, in a granule-discharging machine in which a plurality of granule-feed out parts for feeding out granules in a granule storage tank are installed and a plurality of pipes for sucking the pressure air from an air chamber through which air flows are installed and granules fed out from the granule feed out part by the pressure air fed to each pipe are transferred to each discharge port and discharged.
These problems are solved by constituting a projected area of a pressure air inlet 211 of each pipe 80 in flow direction of air of an air chamber so as to be separately changeable in the granule discharge machine.
