Abstract
An apparatus is offered for controlling the discharge of granular or pelletized material from a tank, consisting of a movable grate (35) between two perforated stationary grates (27, 31), the openings (30, 34) of which are not in alignment. A plurality of scrapers (36) driven back and forth in essentially opposite directions scrapes off the material that has passed through the openings (30) of the first grate (27) and accumulated on the second grate (31) for its controlled discharge while permitting the complete emptying of the tank for easy and rapid cleaning.
