Subtopic: Drying and milling of cereals, pulses and oilseeds
Question Statement:
During test milling of $100\text{ kg}$ of rough rice (paddy), the following milling fractions were obtained: $20\text{ kg}$ husk, $8\text{ kg}$ bran, $54\text{ kg}$ head rice (whole kernels), and $18\text{ kg}$ broken rice. The Head Rice Recovery ($HRR$) in percentage is ________ (answer in integer).
Answer Key:
54
Step-by-Step Solution & Explanation
Head Rice Recovery ($HRR$) is defined as the weight percentage of whole milled kernels obtained from the initial paddy weight:
$HRR = \frac{\text{Weight of head rice}}{\text{Weight of rough paddy}} \times 100 = \frac{54\text{ kg}}{100\text{ kg}} \times 100 = 54\%$
