Only as above stated, the chemical extraction system
requiring complex equipments and higher degree of pres-
sure, the steamed Beans cannot be wrapped up in reed in
the manufacturing process, as in the case of round cake,
for fear of geting cut, and a fabric woven with a higher-
priced human hair or camels’ hair will be wanted for the
purpose, raising the producing cost to that extent.
Moreover, bean plate, assuming an oblong shape and
being of a comparatively small thickness, is liable to break-
age while under transportation, and may be conveniently
packed ‘in gunnies. Moreover, the bean oil put out by the
bean plate system containing protein, if it is subject to a
high temperature, will get discoloured black. For this rea-
son, it needs to be subjected to a refining process. The bean
plate system owing to the excellent quality of bean plate
and the higher oil percentage obtainable than by the round
cake system, is regarded as superior to the other. However,
the greater complexity of equipments, that will fix larger
capital, qu'ck damage done to the enveloping fabric, as
mentioned above, and the necessity to refine bean oil all
conspire to raise its price by nob less than 20 per cent at
least over round cake of the same amount. As long as
bean residues are intended chiefly for manures in Japan
proper, this system is somewhat handicapped, but some-
day when it is used as cattle-feed as in the West, this
