Milling Procedure
Objective: Safely and consistently transform clean grain into ready-to-use flour.
🔍 Selection and Pre-check
Visually inspect 1 lb of grain; discard broken kernels, stones, and foreign seeds
Wash if dusty; air dry for 24 hours
⚙️ Disk Adjustment
Set dial to level 2 for standard bread flour
Ensure free turning with no metal-on-metal contact
🌾 Milling Process
First pass: grind 10 oz continuously (≈8 min)
Sift through mesh 50; collect fine flour
Second pass: regrind coarse fraction; adjust to level 1 for full whole wheat texture
No-electricity safety tips:
• Cotton gloves with non-slip grip
• Keep children at least 3 ft away
• Pause every 10 minutes to prevent overheating

📊 Grain-Flour-Bread Conversion Chart
| Whole Grain (oz) | Flour Yield (oz) | 1 lb Loaves (approx.) |
|---|---|---|
| 17.6 | 16.6 | 1 |
| 35.3 | 33.5 | 3 |
| 70.5 | 66.9 | 6 |
| 176.4 | 167.4 | 15 |
| 352.7 | 334.8 | 30 |
🧮 Scaling Adjustment
For larger or smaller loaves:
Multiply the flour column by
(desired flour weight in oz ÷ 10.6)
(desired flour weight in oz ÷ 10.6)
Example: 26 oz loaf (≃ 15.9 oz flour) → factor 1.5
35 oz grain yields 2 loaves of 26 oz
35 oz grain yields 2 loaves of 26 oz
