Abstract: Rice yield in this
market are still drained manually by using the power of the Sun and dryingprocess
is done in a long time. Moisture content of the product is not uniform, and the
resultingdried grain capacity is limited, because it requires a big place in
the drying process. Rice dryersavailable on the market have not been
manufactured with quality drying is not good because of theuneven results of
drying and drying inefficient. With the above background, the dryer can bedesigned
to work in continuous material and product is can occur at any time. Equipment
dryersare equipped with commutator so that drying can take place constantly.
Testing is done is to take asample of every 1 kg of rice and measured levels of
moisture content. Drying characteristics of optimization testing is to control
the speed of the stirrer shaft, and evaluate the results of testing the uniformity
of drying is to divide the result of drying to 8 mass fraction is then weighed
their respective weight. Tests using rice dryer drum drying with a stirring
mechanism, it can beconcluded that the decrease in moisture content and degree
of drying and drying time is affected bythe speed of rotation of the agitator
shaft is linear. Testing is done by varying the agitator rotation rpm 30, 35
and 40 rpm rpm. On lap 40 rpm going very fast drying results in the material to
becracked. In this study, drying time is used for drying rice as much as 8 kg
with a level of 24% to 14% is 30 minutes with stirring speed 35 rpm,and the
uniformity of drying results 86.6%.
