Abstract
There is here disclosed a resin pellet store device including a silo () in which resin pellets are stored; an discharge route for ON-SPEC products () through which resin pellets having a low content of foreign substances stored above the vicinity of the lowermost part in the silo () are discharged as ON-SPEC products from the silo (); and another discharge route for OFF-SPEC products () through which resin pellets having a high content of foreign substances accumulated in the vicinity of the lowermost part in the silo () are discharged as OFF-SPEC products from the silo (). In consequence, the resin pellets having a high content of foreign substances to be treated as the OFF-SPEC products are clearly sorted out in the silo and discharged therefrom to reduce the content of the foreign substances in the ON-SPEC products. Moreover, the OFF-SPEC products are discharged through another route to avoid the contamination of a downstream facility.
