ABSTRACT:
Freshly cut green-chopped alfalfa is fed into an elongated lightproof dryer, conveyed on successively slower moving perforated conveyor belts in successively thicker layers through successive regions through which decreasing amounts of air heated to respective constant temperatures in the range from roughly 150.degree. F.-600.degree. F. are moved. During daytime operations, a very large solar collector preheats the air, and natural gas powered burner units bring the preheated air up to the respective constant temperatures. At the outlet end of the dryer dehydrated alfalfa is dropped into a first chute which feeds a layer of dehydrated alfalfa through a first crushing system including a pair of high pressure rollers, which crush it, fracturing and breaking the leaves of the alfalfa. This alfalfa then is fed into a second chute which mixes it and feeds it between another pair of high pressure rollers that further break the brittle leaf pieces. The alfalfa then is conveyed to the top of a first separator system that separates the stem pieces from the leaf pieces.
