UJI BERBAGAI TINGKATAN KECEPATAN PUTARAN PADA ALAT PENYANGRAI KOPI TIPE ROTARI TERHADAP KUALITAS HASIL
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
Juni – September
2012 with using
factorial randomized block
design with one factor i.e 10, 35,5 and 61 revolution per
minute. Parameters observed were organoleptic test, yield, process capacity and
water content. The results showed that the RPM had no effect on the
organoleptic test, yield and process capacity, and had highly significantly
effect on the water content.
Key words: Coffee roaster
machine, RPM test, Coffee quality
