ABSTRACT:
The drying apparatus for crop materials particularly alfalfa includes a press with a main press roller and a plurality of subsidiary press rollers which is fed using an additional guide roller cooperating with the transportation belt and guide fingers in the main roller to direct the bulky crop into the nip between the rollers for extracting juice and providing a partially dried crop. The partially dried crop is supplied to a drying apparatus including a tumbling cylinder into which is injected heated air from a ceramic tube heat exchanger fed by a co-generation gas turbine. The gas turbine is used to generate electric power for motors in the apparatus and generates a flow of highly heated air which is passed over the ceramic tubes to heat air drawn into the tumbling cylinder for drying of the crop material.
