RANCANG BANGUN ALAT PENGGILING BIJI KOPI TIPE FLAT BURR MILL
ABSTRAK: Milling was done to
refine food materials to be powder with a certain sieve size in order to be
more easily processed into other products. The purpose of coffee beans milling
was to refine the beans into coffee powder with a certain sieve size in order
to be easily brewed and gives the more optimal sensation of taste and aroma.
This research was aimed to design, make, and evaluate the flat burr mill type
of bean grinder on robusta cofee bean. The bean quality evaluated was the effective capacity
of grinder mill, lost bean
persentage, and economical
analysis. The results showed
the effective capacity of flatt
burr type grinder was 5,00 kg/hr and the
lost bean persentage
was 1,112%. Based on economical analysis, the cost of robusta
coffee bean milling was Rp.1.074,25/kg, break even point 2.748,9 kg/year, net
present value (NPV) 16% was Rp.6.147,25 ,NPV 20% was Rp.5.397.751,98, and
Internal Rate of Return (IRR) was 52.81%.
