Berikut kami berikan contoh perhitungan mencari MI mixing.
contoh:
1. Diketahui:
X1 = 7 zak = 175 kg
X2 = 3 zak = 75 kg
MI1 = 0.26 gr/10min
MI2 = 0.76 gr/10min
2. Ditanyakan berapa MI mix?
3. Jawab:
X1 + X2 = X mix
175 kg + 75kg =250 kg
log 0.26 = - 0.5850
log 0.76 = - 0.1192
Rumus: Xmix . log MI mix = X1. log MI1 + X2. log MI2
250 . Log MI mix = 175 . log 0,26 + 75 . Log 0,76
250 . Log MI mix = 175 . (-0,5850) + 75 . (-0,1192)
250 . Log MI mix = (-102,38) + (-8,9390)
250 . Log MI mix = (-111,319)
Log MI mix = (-111,319)/250 = (-0.4453)
MI mix = 0.36
Jadi MI mix akhir = 0.36 gr/10 min
