5. What are the steps in the edible oil refining process?
The edible oil refining process typically consists of four main stages:
1) Degumming – removal of phospholipids and gums using water or acid.
2) Neutralization (Deacidification) – elimination of free fatty acids through caustic soda treatment.
3) Bleaching (Decolorization) – adsorption of pigments and impurities using bleaching earth.
4) Deodorization – removal of volatile compounds and odors through steam distillation under high temperature and vacuum.
Different oils may require additional specialized steps such as winterization or wax removal. Our refining equipment is available in both batch and continuous configurations to meet various production needs.
6. What is the difference between chemical and physical refining?
The main difference lies in how free fatty acids (FFA) are removed:
Chemical Refining
Uses alkaline solution (NaOH) to neutralize FFAs, creating soapstock that is separated by centrifugation.
Suitable for oils with high FFA content (up to 5-6%) and those containing impurities that are difficult to remove physically.
Typically requires more steps and generates more wastewater.
Physical Refining
Removes FFAs through steam distillation under high temperature and vacuum.
Requires effective pre-treatment (degumming and bleaching) and is best for oils with low FFA content (<2%).
Offers higher oil yield, less chemical consumption, and reduced environmental impact.
We can help you determine the optimal method for your specific oilseeds and production goals.
7. How does a screw oil press machine work?
A screw oil press operates through continuous mechanical compression: Raw materials are fed into the press chamber where a rotating screw shaft conveys them forward.
As the material moves through progressively narrower spaces, tremendous pressure and heat are generated, rupturing oil cells and releasing oil.
The oil drains through gaps in the cage bars while the compressed cake is discharged from the outlet.
Our advanced screw presses feature adjustable pressure control, temperature monitoring, and automated operation for optimal oil extraction efficiency with minimal residual oil in cake.
8. What is the oil yield from soybeans/peanuts/sunflower seeds using your machine?
Oil yield varies depending on seed quality, moisture content, and processing conditions. With our optimized equipment, typical yields are:
Soybeans: 16-20% (using prepress solvent extraction) or 10-12% (mechanical pressing only)
Peanuts: 40-46% (for high-quality shelled kernels)
Sunflower seeds: 28-32% (for dehulled seeds)
We achieve these industry-leading yields through precise temperature control, adjustable pressure settings, and optimized screw design.
Actual results can be verified through material testing at our facility.
9. What is the function of a decolorization tank in oil refining?
The decolorization tank (or bleaching vessel) serves two primary functions:
1) It provides thorough mixing of oil with bleaching earth/clay to adsorb pigments, oxidation products, and residual impurities.
2) It maintains optimal temperature (90-110°C) and vacuum conditions to prevent oxidation and facilitate efficient contact between oil and adsorbent.
Our vertical and horizontal decolorization tanks feature special agitator designs, heating systems, and automatic bleaching earth dosing for maximum efficiency and consistent oil quality.
10. How to maintain a screw oil press machine?
Proper maintenance ensures longevity and consistent performance:
1) Regularly check and adjust screw worm and cage bar wear (replace when necessary).
2) Lubricate bearings according to manufacturer specifications.
3) Clean residual oil cake from press chambers after operation.
4) Monitor motor current and temperature to prevent overload.
5) Inspect seals for leaks.
6) Calibrate temperature sensors periodically. We provide detailed maintenance manuals, video tutorials, and readily available spare parts to minimize downtime. Schedule professional servicing annually for optimal performance.
11. What are the spare parts needed for an oil extraction machine?
Essential spare parts include: pressing cages/worm shafts, gearboxes, bearings, sealing elements, electrical components (sensors, heaters), screens/filters, and wear plates.
The exact requirements depend on your specific equipment configuration.
We recommend maintaining an inventory of critical wear parts to minimize production interruptions.
As your original equipment manufacturer, we offer genuine spare parts kits with guaranteed compatibility and performance.

17. What is the difference between olive oil press and other oil presses?
Olive oil extraction requires specialized equipment to preserve delicate flavors and qualify for “extra virgin” classification:
1) Temperature control must be precise and minimal (cold pressing below 27°C)
2) Processing must be completed quickly after harvesting to prevent oxidation
3) Equipment must avoid excessive pressure that could generate off-flavors
4) Materials must be food-grade stainless steel throughout.
While our standard presses handle various seeds, we offer dedicated olive oil presses meeting these specific requirements for quality-conscious producers.
