Essential Equipment Guide for Small Edible Oil Processing Plant Construction: From Raw Material to Refining

2026-08-09
Qi'e Grain and Oil Machinery Co., Ltd. provides a comprehensive guide for enterprises planning to build small edible oil processing plants, detailing equipment requirements for raw material cleaning, pressing, filtering, refining, and packaging processes, helping you clarify equipment scope and process cohesion.

For enterprises planning to establish a small edible oil processing plant, selecting the right equipment configuration is critical to ensuring production efficiency, product quality, and operational profitability. Qi'e Grain and Oil Machinery Co., Ltd., a leading provider of oil processing solutions with equipment exported to over 120 countries, offers this professional guide to help you understand the essential equipment required from raw material handling to finished oil refining.

Key Considerations for Equipment Selection:

  • Raw material type (soybean, palm, sunflower, rapeseed, etc.)
  • Daily production capacity requirements
  • Desired oil quality standards
  • Available investment budget
  • Future expansion plans

Core Equipment Modules for Small Edible Oil Processing Plant

1. Raw Material Cleaning and Preparation Equipment

Effective cleaning removes impurities that could damage equipment or affect oil quality. Essential equipment includes:

  • Destoner Machine – Separates stones and heavy impurities from oilseeds
  • Seed Cleaner – Removes dust, straw, and light impurities using air separation
  • Magnetic Separator – Eliminates metal contaminants
  • Conditioning Equipment – Adjusts moisture content for optimal pressing (varies by raw material)

2. Oil Pressing Equipment

The pressing stage extracts oil from prepared oilseeds. Qi'e Grain and Oil Machinery offers several options suitable for small-scale operations:

Cold Press Oil Machine

Ideal for producing high-quality, nutrient-rich oils without chemical treatment. Suitable for sesame, flaxseed, and walnut oils.

Automatic Oil Press Machine

Features continuous operation with higher efficiency, suitable for most oilseeds including soybean, peanut, and sunflower seeds.

3. Oil Filtration and Purification Equipment

After pressing, crude oil requires filtration to remove residues and impurities:

  • Plate and Frame Filter Press – Removes solid particles from crude oil
  • Centrifugal Filter – Higher efficiency separation for larger production volumes
  • Bag Filter – Cost-effective solution for small-scale operations

4. Oil Refining Equipment (Optional but Recommended)

For edible oil meeting food safety standards, refining equipment is essential. A basic refining line includes:

Refining Process Equipment Required Function
Degumming Degumming Tank Removes phospholipids
Neutralization Neutralization Reactor Reduces free fatty acids
Bleaching Bleaching Tower Removes pigments and impurities
Deodorization Deodorization Kettle Eliminates odors and volatile compounds

Qi'e Grain and Oil Machinery's edible oil refinery machine solutions are specifically designed for small to medium-scale operations, offering modular configurations to meet different purity requirements.

5. Packaging Equipment

Proper packaging preserves oil quality and extends shelf life. Small-scale packaging options include:

  • Semi-automatic filling machines (for bottles and cans)
  • Capping machines
  • Labeling machines
  • Weighing scales

6. Auxiliary Equipment

Supporting equipment ensures smooth operation of the entire production line:

  • Conveying systems (bucket elevators, screw conveyors)
  • Storage tanks (raw material, crude oil, refined oil)
  • Heating systems
  • Electrical control panels
  • Waste treatment equipment

Equipment Configuration Recommendations

Based on production capacity, Qi'e Grain and Oil Machinery recommends the following configurations:

  • Small-scale (1-5 tons/day): Seed cleaner + Cold press oil machine + Plate filter + Semi-automatic filling machine
  • Medium-small scale (5-20 tons/day): Complete cleaning line + Automatic oil press + Centrifugal filter + Basic refining unit + Automatic packaging line

Our technical team can design customized solutions based on your specific raw materials and production goals.
