Oil Pretreatment and Press Line Process

Feeding

Automated feeding systems ensure a consistent and efficient supply of raw materials to the processing line.

Shelling

By shelling machine remove the outer husks from seeds to protect machinery and improve the final oil’s purity and flavor.

Cleaning

Oil cleaning machine to raw materials are thoroughly cleaned to eliminate all impurities like dirt, sand, and plant debris.

Stone Removal

This destoner machine step removes heavier contaminants like stones and metals to safeguard our crushers and presses.

Magnetic Separation

Magnetic separator powerful magnets extract fine ferrous metal particles, ensuring metal-free, safe oil and protecting equipment.

Crushing

Crush machine grains are crushed to break their cell walls, optimizing oil yield for the pressing stage.

Clean Grain Storage

Processed grains are stored in hygienic silos to preserve freshness for continuous oil production.

Cooker

Cooker machine conditions the meal, adjusting its moisture to prepare for pressing and enhance oil release.

Oil Cleaning Machine

High-efficiency oil cleaning machine removes dust and metals etc, for smooth downstream processing.

Layered Steaming and Wok-frying Pan

Cooker Machine

For oilseeds such as rapeseed and sunflower seeds, multi-layer steam stir-frying is performed to soften the oil and adjust the moisture temperature.

Air Separation Stone Remover

Oilseed Destoner Machine

The wind and vibration are used to screen and remove stones and dirt from the grains.

Product Advantages

1. Boosts Oil Yield: Crushing into uniform particles plus optimized steaming enhances raw material contact with screw oil press, directly improving final oil output. 

2. Ensures Oil Purity: Multi-stage impurity removal (cleaning, stone/magnetic separation) eliminates contaminants, meeting food safety standards. 

3. Flexible Material Adaptation: Tailored shelling, crushing, and steaming fits various oilseeds (soybean, peanut, sunflower), no need for extra equipment. 

4. Reduces Waste: Temporary clean storage prevents raw material spoilage, minimizing loss before pressing. 

5. Smooth Process Flow: Logical step connection (feeding→prep→press ready) cuts downtime, boosting daily production efficiency. 

6. Easy Operation: Integrated steps simplify workflow, reducing training time for workers and lowering operational errors.
