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

⚠️ Common Mistakes and Solutions

1
Issue: Flour gets too hot
Solution: Slow down the crank speed
2
Issue: Irregular texture
Solution: Retighten burr bolts
3
Issue: Loose crank handle
Solution: Check locking pin
4

Maintenance and Cleaning

Objective: Extend the equipment's lifespan and preserve food safety.

🧽 Daily Cleaning

✓
Use a dry stiff-bristled brush on stones and hopper
✓
Lightly damp cloth on exterior; dry immediately

🛠️ Lubrication and Wear Parts

Component Product Frequency
Main shaft Food-grade mineral oil Every 40 hours of use
Rubber gasket Food-grade talc Monthly
Corundum burrs Recondition with whetstone Annually

🔧 Structural Inspection

⚠️
Critical points:
• Cracks in casing → stop use and replace
• Bearing looseness → tighten opposing nut

⚠️ Common Mistakes and Solutions

1
Issue: Using liquid detergent
Solution: Damages burrs; clean dry
2
Issue: Ignoring metallic noises
Solution: Check alignment immediately
3
Issue: Storing while damp
Solution: Rust risk; apply protective oil
5

Rotation and Storage

Objective: Ensure a stable and high-quality supply throughout the year.

📊 Family Needs Calculation

Family of 4 people, daily bread
14 oz flour/day → 320 lbs grain/year
Add 10% strategic buffer: 350 lbs

🔄 Simplified FIFO Method

Label each bucket with filling date (MM-YYYY)
Always consume the oldest first
Replenish quarterly

🌡️ Optimal Storage Conditions

°F
Temperature: 50–65 °F
%
Relative humidity: ≤ 60%
💧
Passive dehumidifier: calcium chloride in tray
🚨
Signs of deterioration:
• Rancid or musty smell
• Presence of moths or webs
• Dull or discolored appearance

⚠️ Common Errors and Solutions

1
Issue: Mixing different harvests
Solution: Affects baking; separate by batch
2
Issue: Storing directly on concrete floor
Solution: Use wooden pallets
3
Issue: Not checking O₂ absorbers
Solution: Weigh every 6 months (≤ 5% weight gain)

📊 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)
Example: 26 oz loaf (≃ 15.9 oz flour) → factor 1.5
35 oz grain yields 2 loaves of 26 oz
