Peanut oil refining equipment

September 18, 2021


Peanut oil refining equipment will make peanut oil have low fatty acid content, tasteless, odorless, good color, transparent and free of impurities. For the pressed peanut oil obtained from fine peanut kernels, the refining process should be minimized to retain the natural flavor of peanut oil. According to different oil materials, different crude oil preparation processes, different customer requirements for finished products, different processing capacity and different refining methods, our company's peanut oil refining equipment is divided into three types: batch refining equipment, semi-continuous refining equipment Refining equipment, full continuous refining equipment.


Advantages of peanut oil refining equipment:


1. Through dephosphorization, decolorization, deacidification, deodorization and other processes, the peanut oil refining equipment can make the crude oil meet the national standard of oil quality.


2. Peanut oil refining equipment has small investment and quick return, suitable for users of small-scale production and processing.


3. Small footprint, flexible equipment operation, and labor saving.


4. Peanut oil refining equipment is suitable for refining a variety of oils, which is conducive to the expansion of users' business.


5. The refining process that combines chemical and physical methods greatly accelerates the quality of refined oil.


6. Each refining stage of peanut oil refining equipment is designed separately, which is conducive to the later expansion of production scale.


Refining process of peanut oil refining equipment:


The oil press method to produce fragrant peanut oil requires the use of fine, freshly harvested peanuts to peel the kernels and remove impurities thoroughly. The fragrant peanut oil is usually not refined and processed, but directly used as edible oil after solid impurities have been removed. If the fragrant peanut oil obtained is of poor quality, it should be refined, but the aroma of the refined oil will be greatly reduced at this time. For pressed peanut oil obtained from fine peanut kernels, the refining process should be minimized to preserve the natural flavor of peanut oil. The crude peanut oil obtained by solvent leaching of peanut cake should be fully refined. The process of refining the leached peanut crude oil into ordinary peanut oil is the same as that of ordinary soybean oil.


The refining process of peanut advanced cooking oil and salad oil is as follows:


Low quality

Peanut oil → hydration and degumming → alkali refining and deacidification → decolorization → deodorization → winterization and dewaxing → solid wax

What are the characteristics of peanut oil refined by peanut oil refining equipment?


1. Color: The oil refined by the peanut refining equipment is crystal clear, while the crude oil is turbid in color.


2. Odor: Peanut refined oil has a light oily fragrance and no peculiar smell. Crude oil has peculiar smells such as fishy smell, grass smell, rust smell and so on.


3. Health: through peanut refining equipment, remove the unhealthy magazines from peanut crude oil that are harmful to food and storage to obtain refined oil that meets national quality standards. The moisture, impurities, acid value, and peroxide value in the oil all meet the national quality standards, and are not easy to rancidity and deterioration, but are conducive to storage, do not produce a large amount of oily smoke during cooking, and maintain the flavor of the oil. Crude oil refers to the primary oil that is made from animals or plants and has not been refined. Because of the simple processing technology, crude oil contains many impurities and is easy to oxidize and deteriorate. It is not suitable for long-term storage, may have problems such as residual pesticides, heavy metal pollution, and contains harmful substances. Another characteristic of crude oil is that it has a lot of foam, peculiar smell and heavy oily smoke when cooking and heating, which obviously affects the smell and taste of cooking food.
