ABSTRACT:
Tablets, pills or like discrete products are fed into the upper section of an upright conduit to descend into a vessel under the action of gravity. Excessive acceleration of descending products is opposed by an air stream which is induced by a pump and flows in the conduit counter to the direction of advancement of the products. The vessel contains one or more partitions which have outwardly and downwardly sloping upper sides and central openings for the conduit. The outlet of the conduit discharges products first onto the bottom wall of the vessel and thereupon at a level above the lowermost partition which latter causes the products to slide outwardly toward the sidewall of the vessel. When the space between the bottom wall and the lowermost partition is filled, the lowermost partition prevents crushing of products below it under the weight of products which gather above the lowermost partition. The next higher partition performs the same function by preventing crushing of products which gather between the two lowermost partitions, and so forth. The vessel and the conduit can define a sealed endless path for the flow of a continuous air stream.
