ABSTRACT:
A method is provided for filling seed trays particularly tobacco seed trays, with growing filler material whereby dry pockets are prevented from forming in the seed trays. The method includes partially filling an upright loading device with the filler material in a manner so that the surface plane of the filler material is at an inclined angle of repose with respect to horizontal. A leading edge of the filler material is established and maintained from the front end of the loading device. A seed tray is passed below the loading device so that the forward edge of the seed tray initially passes below the leading edge of the filler material so that the filler material cascades down into the individual pockets of the seed tray at a controlled rate. In practicing this method, the individual pockets of the seed tray are generally completely filled from the bottom up with the filler material before being conveyed under the bulk portion of the filler material, thereby minimizing the occurrence of dry pockets.
