Corn Shrinkage Calculator

The Corn Shrinkage Calculator determines the weight loss of corn during the drying process, accounting for the reduction in moisture content and handling losses. Shrinkage calculations are essential for farmers, grain handlers, and buyers to estimate post-drying weights accurately, helping in storage planning, sales pricing, and profit analysis.

The calculator uses industry-standard formulas to provide precise estimates of shrinkage, ensuring transparency in corn transactions and efficient crop management.

Formula of Corn Shrinkage Calculator

Shrinkage Percentage:

Shrinkage (%) = [(Initial Moisture – Final Moisture) × Shrink Factor] + Handling Loss

Weight After Shrinkage:

Weight After Shrinkage = Initial Weight × (1 – Shrinkage / 100)

Detailed Formula Components:

1. Initial Moisture:
   The starting moisture content of the corn, expressed as a percentage.
2. Final Moisture:
   The target moisture content after drying, expressed as a percentage.
3. Shrink Factor:
   A standard factor used to estimate weight loss due to moisture removal. For corn, this is typically 1.18.
4. Handling Loss:
   An additional percentage to account for mechanical losses during drying, usually between 0.5% and 1%.
5. Shrinkage (%):
   The total percentage of weight lost during drying, combining moisture removal and handling losses.
6. Weight After Shrinkage:
   The remaining weight of the corn after accounting for shrinkage.

Key Notes:

• Accurate moisture readings are critical for precise calculations.
• Handling loss varies depending on the drying equipment and conditions.

Example of Corn Shrinkage Calculator

Scenario:

A farmer starts with 10,000 pounds of corn at 25% moisture and plans to dry it to 15% moisture. The shrink factor is 1.18, and handling loss is estimated at 0.5%.

Step-by-Step Solution:

1. Calculate Shrinkage Percentage:
   Shrinkage (%) = [(Initial Moisture – Final Moisture) × Shrink Factor] + Handling Loss
   Shrinkage (%) = [(25 – 15) × 1.18] + 0.5
   Shrinkage (%) = (10 × 1.18) + 0.5
   Shrinkage (%) = 11.8 + 0.5
   Shrinkage (%) = 12.3
2. Calculate Weight After Shrinkage:
   Weight After Shrinkage = Initial Weight × (1 – Shrinkage / 100)
   Weight After Shrinkage = 10,000 × (1 – 12.3 / 100)
   Weight After Shrinkage = 10,000 × 0.877
   Weight After Shrinkage = 8,770 pounds

Result:

After drying, the corn weighs approximately 8,770 pounds.
