Dingsheng Machine | Complete Corn Germ Oil Extraction Solutions (10–6000TPD)
Date:Nov 28th, 2025
Dingsheng Machine specializes in providing complete corn germ oil extraction plants with full turnkey service. Our engineering team delivers customized solutions for capacities ranging from 10 TPD up to 6000 TPD, covering everything from design, manufacturing, installation to commissioning.
Important note:
Corn germ must be available in sufficient quantity—typically 100 tons of corn yield only about 8 tons of corn germ. Since equipment for producing corn germ from corn kernels is highly specialized and costly, Dingsheng Machine does not produce germ-separation machinery. We recommend that customers purchase corn germ directly or own a starch/ethanol plant that generates corn germ as a by-product.

Where corn germ comes from
Corn germ is the oil-rich part separated during corn starch or ethanol production. With proper pretreatment and extraction processes, it becomes a valuable source of edible oil and protein meal.

Three Major Sections of Dingsheng Corn Germ Oil Processing Line
Ⅰ. Pretreatment & Prepressing Section
Process flow:
Corn germ → Cleaning → Conditioning → Flaking/Cooking → Prepressing → Extraction section
This stage determines the efficiency of the entire production line. A well-designed pretreatment system ensures stable operation and maximizes the extraction rate.
Key Features of Our Pretreatment Systems
Establish stable and clean production conditions
Maximize oil yield and protect nutrient components
Ensure high-quality meal for solvent extraction
Reduce processing losses and energy consumption
---
Ⅱ. Solvent Extraction Section
Process flow:
Solvent extraction → Mixed oil → Evaporation → Desolventizing → Stripping → Crude corn germ oil
Our extraction plant adopts an advanced negative-pressure evaporation system, ensuring both safety and superior oil quality.
Advantages of Dingsheng Solvent Extraction Systems
High oil recovery with low residual oil in meal
Low labor intensity with stable automated operation
Clean workshop environment with efficient exhaust treatment
High-quality meal suitable for feed production
Energy-saving layout with multiple heat-recycling options
Technical Highlights
Flexible design adaptable to different raw material conditions
Complete absorption system for solvent gas treatment
Optimized evaporation process improves crude oil quality
---
Ⅲ. Refining & Dewaxing Section
Process flow:
Degumming → Neutralizing → Decolorizing → Deodorizing → Dewaxing → Finished refined corn germ oil
Our refining equipment supports both batch and continuous operation.
Features of Dingsheng Refining Line
Continuous alkali refining minimizes saponification and reduces loss
Combined premix + steam bleaching improves color stability
Negative-pressure bleaching avoids oxidation and protects oil stability
New-type continuous deodorizer ensures excellent flavor and low acid value
Heat-exchange system lowers steam usage and reduces operating costs
The final refined corn germ oil meets international edible oil standards and is suitable for bottling or further fractionation.
---
