ABSTRACT:
A device and method are disclosed for treating compressible materials, such as hay or other fibrous materials, with a treating substance, preferably anhydrous ammonia, as a preservative for the treated compressible material. The treating substance is preferably introduced into a treating area as a gas, but may be introduced in aqueous or liquid form to establish a fog of treating substance in the treating area.
The compressible material to be treated is introduced into the treating area which preferably has air locks, established by a pair of pressure rollers, at both the compressible material inlet and outlet to maintain the treating substance within the treating area.
Within the treating area, a path is established for continuous movement of the compressible materials from the inlet to the outlet rollers. This path is shown to be established by a pair of endless conveyor belts forming an arcuate path through which the compressible material is conveyed by the belts, by spaced arcuate guides having spikes extending therethrough to cause movement of the compressible material along the path established by the guides, and by spaced straight bars extending downwardly at an angle from inlet to outlet so that compressible material moves under the force of gravity from the inlet to the outlet.
The treating substance introduced into the treating area is maintained under constant circulation by a fan so that the compressible material is entirely and uniformly contacted while in the treating area.
