Abstract: Corn (Zea mays L.)
is one of the important world food crops, other than wheat and rice. Because
corn is an important role as a source of food and medicine, the post-harvest
handling is very important because it determines
the quality of the corn for the next use. Drying process by adsorption is an
option to replace conventional corn drying systems. In our study, the zeolite
as adsorbent was mixed with corn in campfire the fluidized with air at 30-50oC.
The air will evaporate water from the corn, and at the same time, the zeolite
will absorb the water from the air, so the humidity will be maintained low.
Thus heat consumption can be lowered and drying will become faster. Required
materials in this study are corn and zeolite. Research conducted using fixed
variable sampling time (15 minutes). Incoming air temperature(room temp, 30oC,
40oC, 50oC) and ratio between corn and zeolite drying the corn, characterization
must do first. The dried corn tested the water, protein, fat contains and the
colors. The results from this research show the best variable is variable with
ratio between corn and zeolite (1:0, 1:3, 1:1, 3:1) are used as changing
variables. Before appropriate with SNI standard for dried food ( 14 % ) is
variable using incoming air temperature 40oC and 50oC
with ratio between corn and zeolite 1 : 3 and using incoming air temperature
50oC. The suitable variable andappropriate with SNI standard for dried food (
14 % ) is variable using incoming air temperature 40oC and 50oC with ratio
between corn and zeolite 1 : 3.
