New Type Commercial Sunflower Oil Mill Sunflower Oil Refined

New Type Commercial Sunflower Oil Mill Sunflower Oil Refined is a general term for the removal of solid impurities, free fatty acids, phospholipid, colloid, wax, pigment and odors in vegetable oils. The presence of impurities contained in crude oils not only affects the use value, the safety storage of crude oil, but also cause difficulties for the deep processing crude oils. Edible oil refining is not only removes all the impurities out from the crude oils, but also refines harmful impurities, such as, gossypol, protein, lecithin, mucus, water and more. In this way, the edible oils can have better storage, industrial applications and cooking purpose. However, some beneficial substances, such as tocopherol, sterol and more, will be maintained.

Sunflower seed oil is rich in nutrients. Its unsaturated fatty acid (a nutrient beneficial to human body) accounts for more than 85% of the total fatty acid. Its quality can be comparable to that of virgin olive oil. Therefore, sunflower seed oil has become the preferred edible oil for more and more people who pay attention to dietary health. The market prospects for sunflower seed oil production are very broad.

Sunflower seeds can be divided into two kinds: edible sunflower and oil sunflower. Between them, edible sunflower seeds have large grains, oil content is about 30%, and the shell is black-white striped; oil sunflower seeds have small grains, oil content can reach more than 55%, and the shell is mostly pure black. Customers planning to use sunflower seeds for oil extraction should pay attention to this distinction in order to avoid economic losses for you.

Working principle of sunflower seed oil press machine:

When the oil press machine works, pour the pre-treated oil cake into the chamber from the hopper. When the screw rotates, it continuously pushes the oil cake inward. Through the mutual extrusion of the chamber, the screw and the oil cake, the oil in the oil cake is extruded and discharged from the drainage tank of the oil press.

Advantages of Hongde Grain And Oil Machinery Co., Ltd. sunflower seed oil press machine:

On the basis of summing up production practice experience, we optimized the internal structure of the New type commercial sunflower oil mill.

Comparing with ordinary oil press machines, the pressure inside the chamber of the oil press produced by us is higher and the distance of embryo in the chamber is longer, so the oil extraction efficiency of our oil press is improved and the residual oil rate of oil is reduced to the minimum.

In the fragile parts of the equipment, we use high quality alloy steel to build, which significantly improves the overall service life of the equipment.

Generally speaking, the process of oil extraction is divided into three parts: pretreatment, oil extraction and refining.

Pretreatment refers to the removal of oil shell and impurities in oil seeds by various machines or manual means, which can improve oil extraction efficiency, reduce equipment wear and improve oil quality.

There are two ways to get oil, one is to press oil, the other is to extract oil. We should according to the daily capacity and the different oil seeds, choose a better way of extracting oil. If you have a plan to establish an edible oil extracting company and want to know more about the industry, please contact us. We will arrange professional sales engineers for each customer to solve your problems.

Refining is the removal of impurities from the extracted oil by various physical and chemical means, which makes the oil clear in color, fragrant in smell and has a longer shelf life.

Oil refinery is to selectively separate oil accompaniment from oil by physical and chemical methods. It aims to remove harmful ingredients to human body to enhance oil storage stability, to improve oil flavour and color.

Oil refinery process includes hydration degumming, alkali deacidification,absorption decolorization,high-temperature vacuum deodorization.Our technology is suitable for most oil,such as lard, beef tallow, chicken oil, fish oil, soybean oil, rapeseed oil, sunflower oil, peanut oil, sesame oil,cottonseed oil, rice bran oil, palm oil, peony seed oil, tea seed oil, flaxseed oil, etc

Refinery Process

The process:

Degumming- neutralisation- washing & vacuum drying:

Chemical refining is subject to degumming, neutralization and washing process to remove hydratable, and non-hydratable phosphides, FFA, soap PPM and some coloring bodies from the oil. In this process oil is heated to the suitable de-gumming temperature and water as well phophoric acid is added for de-gumming. Subsequently diluted caustic is mixed with the oil to convert the FFA into soap. Gum and soap is subject to centrifugal separation. Lastly, oil is washed with hot water to remove the last traces of soap PPM.

Pretreatment:

During physical refining, oil is subject to phosphoric acid addition for the phopshotides to react with phosphoric acid. Proper retention ensures phosphoric acid and phopshotides to react with each other properly.

Bleaching:

During physical refining, pretreated oil and during chemical refining, neutral oil is subjected to the bleaching process. Pretreated / neutral oil contains yellow, green and red pigments. This is a physical absorption process where the oil is heated to the required bleaching temperature and then bleaching earth is added which absorb the coloring bodies. This oil passes through pressure leaf filters and then the polishing filter.

De-acidification/Deodorization:

Oil after neutralization, pre-treatment and bleaching contains FFA, few coloring bodies and odoriferous substances. These odoriferous substances impart color and foul smell to the oil and to remove these, oil is subjected to de-acidification / deodorization using high vacuum, open steam with suitable residence time. This oil is then cooled and antioxidants to increase the shelf life of refined oil.
