Abstract: In successive cycles of movement of packing panel means in a hopper, refuse is stuffed at high pressures into a progressively narrowed throat in the hopper and is churned, fragmented and compacted during such stuffing operation. At positions beyond the throat, the refuse is directed at reduced pressures through the passage into a storage body. When the pressure of the refuse in the passage reaches a particular value, a servo obtains the movement of an ejection panel in a direction to relieve such pressure. A retainer panel is movable, in accordance with the cyclic movement of the packing panel means through the hopper, between a first position opening the passage and a second position closing the passage and is disposed in the first position to define an extension of the passage. A distance accommodating human fingers is provided between the edge on the packing panel means and a curved inner surface in the hopper at a point adjacent to a sill in the hopper.
