OIL PRESS RAW MATERIALS GUIDE
Best seeds and nuts for extraction
Introduction
Selecting the right raw material is crucial for successful oil production. Different seeds and nuts have varying oil content, processing requirements, and market values.
Choosing the right raw material can significantly impact production efficiency and product quality. Understanding each material's characteristics is key to maximizing yield.
Understanding Raw Material Characteristics
Key Characteristics
Oil Content
Higher oil content = higher yield per kg
Moisture Content
Critical for optimal extraction (too dry = reduced yield, too wet = emulsification)
Seed Size & Shape
Affects grinding efficiency
Hardness
Determines required press pressure
Market Value
Premium oil = higher profit margins
Common Oil Materials
Sesame Seeds
Peanuts
Rapeseeds
Walnuts
Almonds
Coconut
Soybeans
Material Preparation Best Practices
Seed Cleaning
Remove debris (stones, metal, dust)
Separate damaged and broken seeds
Target: < 0.5% debris
Moisture Adjustment
Too dry: Add water with spray humidifier
Too wet: Dry with hot air dryer or sun drying
Roasting (Hot Press)
Sesame: 160-180°C, 25-30 min
Peanut: 165-185°C, 30-35 min
Rapeseed: 150-170°C, 20-25 min
Grinding
Optimal particle size: 2-4 mm for most materials
3-5 mm for nuts
Storage and Handling
Storage Conditions
Temperature
15-25°C
Humidity
< 65% relative humidity
Duration
< 6 months for best quality
Pest Control
Use rodent-proof containers, regular inspection
