PERHITUNGAN NERACA MASSA KRISTALISASI pada PROSES PRODUKSI GULA

PERHITUNGAN NERACA MASSA KRISTALISASI

Brix bahan:
BLQ         = 62%
WHM         =76%
Foundan     = 82%
Brix produk:
W masequite pan 4W = 89,88%
W masequite pan 5W = 90,71%
W masequite pan 6W = 92,26%

1.    Pembuatan bibit pada pan 5W
Bahan masuk:     -WHM = 210 HL
            - BLQ = 190 HL
            -foundan = 2 L
Perhitungan brix bibit:
In = out
(Brix BLQ x jumlah BLQ) + (Brix WHM x jumlah WHM) + (brix foundan x jumlah foundan) = brix bibit x jumlah bibit
(62% x 19000L) + (76% x 21000L) + (82% x 2L) = brix bibit x 37000
11780L + 15960L + 1,64L = brix bibit x 37000L
Brix bibit= 27741,64L / 37000L
            = 75%
Bibit akan dialirkan ke pan 4W sebanyak 150HL dan pan 6W 120 HL, sedangkan sisanya 100 HL digunakan untuk masakan 5W

2.    Neraca massa masakan 5W
Bahan masuk: -WHM = 100 HL
        - BLQ = 130 HL
        - Bibit = 100 HL
In = out
(Brix BLQ x jumlah BLQ) + (Brix WHM x jumlah WHM) + (brix bibit x jumlah bibit) = brix W masequite x jumlah W masequite
(62% x 13000L) + (76% x 10000L) + (75% x 10000L) = 90,71% x P
8600L + 7600L + 7500L = 90,71% x P
            P = 23700 L / 90,71%
            P = 26127 L
Air teruapkan = 33000L – 26127L= 6872 L

3.    Neraca massa masakan 6W
Bahan masuk: -WHM = 80 HL
        - BLQ = 160 HL
        - Bibit = 120 HL
In = out
(Brix BLQ x jumlah BLQ) + (Brix WHM x jumlah WHM) + (brix bibit x jumlah bibit) = brix W masequite x jumlah W masequite
(62% x 16000L) + (76% x 8000L) + (75% x 12000L) = 92,26% x P
9920 L + 6080 L + 9000 L = 92,26% x P
            P =  25000 L / 92,26%
            P = 27097 L
Air teruapkan = 36000L – 27097L= 8902 L

4.    Neraca massa masakan 4W
Bahan masuk: -WHM = 70 HL
        - BLQ = 110 HL
        - Bibit = 150 HL
In = out
(Brix BLQ x jumlah BLQ) + (Brix WHM x jumlah WHM) + (brix bibit x jumlah bibit) = brix W masequite x jumlah W masequite
(62% x 11000L) + (76% x 7000L) + (75% x 15000L) = 89,88% x P
6820 L + 5320 L + 11250 L = 89,88%x P
            P = 23390 L / 89,88%
            P = 26023 L
Air teruapkan = 33000L – 26023L= 6976 L
