Evaluation of an on farm press
Publication, American Society of Agricultural Engineers (4-82): 247-251
A farm scale press was evaluated in terms of throughput, oil removal, quality of oil, and effect of seed conditions on throughput and oil quality of rapeseed. The press consists of a driven constant pitch worm inside a cage of 12 triangular shaped plates arranged perpendicularly to the axis of the worm. Preliminary indications are that the press is very reliable. Oil output of 9-10 litres/hr has been attained for seed with an m.c. of 6-7%. Throughput drops off from 25 to 15 kg/hr and oil removal worsens considerably when seed with an m.c. of 9-10% is expelled.
