UJI KECEPATAN PUTARAN OPTIMAL PADA ALAT PENYANGRAI KOPI TIPE ROTARI TERHADAP KUALITAS HASIL SANGRAI
ABSTRACT: The RPM of coffee
roaster mixer tool is needed to care. The machine RPM will affect the roasting
quality. Various level of PRM were tested
to know the
quality of coffee
produced. Research had
been conducted at
agricultural engineering laboratory,
faculty Agricultural USU in July till October 2013 with using factorial
randomized block design with one factor i.e 15, 25, 35, 45, and 55 revolution
per minute. Parameters observed were organoleptic test, yield, process capacity
and water content. The results showed that the RPM had highly significantly
effect on the organoleptic test, yield, process capacity, and water content.
