High-efficiency copra oil extraction and refining process solutions

Copra oil (also known as coconut oil) is a natural, stable, and versatile vegetable oil widely used in the food, daily chemical, pharmaceutical, and industrial sectors. With the continued growth in international demand for high-quality refined coconut oil, investing in an efficient, energy-saving, and automated copra oil production line has become a strategic choice for many oil processing companies.

So, how can dried coconut meat be efficiently converted into high-quality coconut oil? This depends not only on high-quality raw materials, but more importantly on a systematic processing technology design. Today, we'll delve into this scientific journey "from coconut to oil."

I. Detailed Explanation of the Extraction Process of Coconut Oil

The first step in producing high-quality copra oil is the scientific processing of raw materials. The ideal moisture content for copra is between 7% and 10%; too high a moisture content makes it prone to mold, while too low a moisture content affects the oil yield.

• ✅Raw material pretreatment : Through steps such as magnetic separation to remove iron, crushing and screening, softening and steaming, the coconut meat particles are heated evenly, creating the best conditions for subsequent oil release.
• ✅Double -helix pressing + solvent extraction : First, mechanical pressing is used to remove most of the oil, and then hexane solvent extraction is used to reduce the residual oil rate to below 0.8%, significantly improving the overall efficiency.
• ✅Crude oil purification : triple purification of sedimentation, filtration and centrifugation ensures that the crude oil is clear and transparent, laying a solid foundation for subsequent refining.

II. Coconut Oil Refining Process

Many customers mistakenly believe that "refining = destroying nutrients," but that is not the case! QIE Group uses a fully continuous physical refining process with no chemical additives throughout, which preserves the natural stability of coconut oil and meets European and American food safety standards.

III. Cold pressing vs. hot pressing? Physical vs. chemical refining? How to choose without making a mistake?

Different processes determine the positioning and value of the final product. Let us help you clarify your thinking:

V. FAQ

Q1: How to increase the oil yield of copra oil?

It is recommended to use a combination of "pre-pressing + solvent extraction" process, which can reduce the residual oil content of the oil cake to below 0.8%. At the same time, controlling the moisture content of the copra at 7%–10% and optimizing the steaming and roasting temperature and pressing pressure can significantly improve the oil yield.

Q2: What are the key steps in refining copra oil?

The main steps include degumming, deacidification, decolorization, and deodorization to ensure that the product has a clear color, no odor, and high stability.

Q3: Is physical refining more expensive than chemical refining?

Physical refining requires a slightly higher initial investment, but has lower long-term operating costs, no wastewater treatment fees, less oil loss, and better overall economic benefits.

Q4: Can QIE Group's production lines be customized?

We can provide full-process customization from 10 tons/day to 3000 tons/day, including process design, equipment selection and plant layout, to meet the investment and capacity needs of different customers.
