Product Overview – What Is a Hot Press Oil Press Machine?

The Vos hot press oil press machine is a thermally enhanced screw press designed for high-efficiency oil extraction. Through controlled heating before and during the pressing process, the machine improves oil flow, reduces viscosity, and breaks down cellular structures in oilseeds more effectively. It’s particularly suitable for peanut, soybean, rapeseed, sunflower seed, and other medium- and high-oil-content materials.

This equipment is widely used in medium to large-scale oil mills, commercial edible oil plants, and industrial oil production facilities seeking consistent output and high oil recovery.

How Hot Oil Pressing Works

Seed Heating: Raw oilseeds are preheated using a separate cooker or built-in electric heating to soften cell walls and initiate oil release.

Mechanical Pressing: Heated seeds are gradually compressed inside a screw press chamber under high pressure and temperature.

Oil Discharge: Extracted oil passes through filter gaps while the residual press cake is discharged for byproduct processing or further extraction.

Advantages of Hot Press Oil Extraction

Vos hot press oil press machines are installed in countries including India, Nigeria, Uzbekistan, Ghana, and Bangladesh, where bulk edible oil production is critical for domestic and export markets. These machines are often deployed as part of complete turnkey systems, including cookers, conveyors, filtration systems, and oil storage tanks. It also have such advantages :

Higher Oil Yield: Heat softens cell structures, increasing oil recovery rate by 5–10% compared to cold press.

Faster Throughput: Reduced viscosity allows quicker oil release and higher daily capacity.

Better Oil Flow: Heated oil flows more smoothly, reducing blockage and wear.

Strong Flavor & Aroma: Resulting oil often has a distinctive roasted flavor (for edible markets).

Stable Cake Discharge: Drier and firmer press cake suitable for use in feed or extraction by solvent.

Frequently Asked Questions (FAQ)

1. What’s the difference between hot and cold oil pressing?

Hot pressing uses heat to improve oil yield and flow, making it ideal for large-scale production. Cold pressing retains more nutrients but yields less oil.

2. Is hot-pressed oil safe for consumption?

Yes, hot-pressed oil is widely consumed, though it often requires refining to improve clarity and shelf stability.

3. Can the same machine be used for different materials?

Absolutely. Vos hot press machines are suitable for soybeans, rapeseed, peanuts, cottonseed, and more. Pre-treatment may vary slightly depending on the material.

4. Do I need a separate cooker?

Smaller models can use electric heating; larger models typically come with integrated cookers for continuous preheating.

5. Does Vos support turnkey solutions?

Yes. Vos provides full-process solutions including design, production, installation, and after-sales service for hot oil press lines.
