Subtopic: Drying and milling of cereals, pulses and oilseeds
Question Statement:
In a modern rice mill, $2500\text{ kg}$ of cleaned paddy with $14\%$ moisture content is milled. The milling yields $1750\text{ kg}$ of total milled rice (including brokens), which contains $1400\text{ kg}$ of whole unbroken head rice. The Head Rice Yield ($HRY$) of the paddy expressed as a percentage of the raw paddy feed is ________ % (answer in integer).
Answer Key:
56
Step-by-Step Solution & Explanation
Head Rice Yield ($HRY$) is defined as:
$HRY = \frac{\text{Mass of head rice}}{\text{Mass of rough paddy feed}} \times 100$
$HRY = \frac{1400\text{ kg}}{2500\text{ kg}} \times 100 = 56.0\%$
