COMPLETE PEANUT OIL PRESSING GUIDE
Comprehensive guide to peanut oil production from raw materials to finished oil
Why Peanut Oil Pressing Rewards Good Preparation
Peanut oil is one of the most popular cooking oils in the world, known for its high smoke point, neutral taste, and nutritional benefits. This comprehensive guide covers all aspects of peanut oil production, from raw material selection to pressing and finished oil.
Whether you are setting up a small-scale production facility or a large commercial factory, this guide provides technical parameters and best practices to achieve high-quality peanut oil with maximum yield.
Preparing Peanuts for Pressing
Understanding Peanut Types
| Peanut Type | Characteristics | Best For |
|---|---|---|
| Runner | Medium size, uniform seeds | General oil production |
| Virginia | Large seeds, high quality | Premium oil, export |
| Spanish | Small seeds, high oil content | High yield production |
| Valencia | Multiple seeds per pod | Niche market |
Raw Material Requirements
Moisture Content
7-9% for cold pressing, 5-7% for hot pressing
Oil Content
45-55% (good quality peanuts)
Impurity Level
Less than 0.5%
Aflatoxin Level
AFB1 โค 20 ฮผg/kg (retail compliance)
Peanut Oil Pressing, Step by Step
Shelling
Required for all peanut oil production
Target: Shelling rate > 95%
Equipment: Disc dehuller or hammer mill
Cleaning
Remove stones, metal, and other hard impurities
Magnetic separation for metal contaminants
Gravity separation for light impurities
Sorting
Visual inspection for moldy or damaged seeds
Optional: Optical sorting by color and quality
Hot Pressing Process
Hot pressing is the most common method for peanut oil production, offering higher yield and faster processing time.
Equipment Configuration
Complete Hot Pressing Line:
- 5 x Electric Heating Flat Pans (100 kg/batch)
