What is the difference between refined and unrefined palm oil and which one is preferable for consumption?

No matter refined palm oil or unrefined palm oil all is extracted from the palm fruit. The big difference between refined and unrefined palm oil is the way in which the oil is extracted and how it's subsequently processed. Another big difference between refined and unrefined palm oil is the oil quality, including the solid impurities content, oil color, acid value, flavour.  

Major difference 1: palm oil extraction way

Unrefined palm oil refers to extract palm oil out from palm fruit. The most widely used palm oil machine is palm oil press machine.

 Hot sale small scale palm oil press machine

The refined palm oil processing process is complex compared with unrefined palm oil. Firstly, we need to use palm oil press machine or palm oil processing machine extracts palm oil out. After get crude palm oil, we need to use palm oil refining machine to refine crude palm oil. After palm oil refining process, we can get refined palm oil.

 

Major difference 2: the oil quality

Compared with unrefined palm oil, the refined palm oil flavor is more better, color and smell of palm oil is improved, the stability is improved which is good for long time storage.

But i need to tell you is that refining is not remove all the impurities in crude palm oil, but selectively remove impurities. For example, moisture not only affects the transparency of the oil but also promotes the rancidity of the oil; FFA affects flavor and promotes oil bad; and so on. Thus, cooking oil refining processing line is necessary for most kinds of cooking oil production process.

As for which one palm oil is preferable for consumption? I think the answer is not the only. When we visit Nigeria, we see there are some people eat palm oil straightly after pressing and no refining. And not only Nigerian, but lots of people in Africa do not refining for palm oil.

But with the improvement of people's living standard, i believe more and more people will pay attention to better quality palm oil.

How about our 1-5tph palm oil making process?

Due to the difference in production capacity, palm oil making processes will be slightly different, the standard 1-5tph palm oil making process roughly includes: raw material reception, sterilizing, threshing, digesting, pressing and filtering. Doing Company has a rich experience in the palm oil making equipment manufacturing and palm oil plant installation, today, let me introduce you the specific palm oil making process. For the making process with small processing capacity, you can refer to: How to extract palm oil at home?

5tph small scale palm oil mill

Firstly, we should receive the palm fruit bunches timely. As we all know, fresh oil palm had better to being processed in the 48 hours after harvesting. So, it is necessary to install a raw material receive station to ensure the unity of material freshness. And it is also helpful to calculate palm oil yield by weighing the materials on this station.

Secondly, we can use the sterilizer to sterilize the oil palm fruit. In this step, sterilizer aims to make palm fruit bunches softer, which is convenient for subsequent processing. At the same time, sterilization can destroying enzymes in the flesh to prevent the free fatty acid content in the oil from rising.

Thirdly, we can use the drum type thresher to separate the palm fruits and the empty palm fruit bunches. Then we can transform the palm fruits to the following pressing station.

Fourthly, we usually use the digester and the palm oil press machine mashed the whole palm fruit into palm fruit pulp, and then palm oil is squeezed from the fruit pulp by the external mechanical force of the palm oil press machine. This step is also the most important step in the whole palm oil making process and the palm oil press machine is also the core equipment of all palm oil making machines. Lastly, we may filter the crude palm oil by plate and frame filter to remove the impurities in the crude palm oil.

How to obtain bleaching palm oil? What process do we need?

We all know that if we want to get palm oil, we need to conduct several steps of sterilizing, threshing, pressing, filtering and drying. But at this time, the palm oil we obtained is red crude oil. If we want to get bleaching palm oil, we need to refine crude palm oil.

Generally speaking, bleaching is a part of palm oil refining. Only after refining, we will get odourless, yellow and easy to preserve palm oil. Refining requires the following steps.

1. Degumming: We generally have two methods: hydrating degumming and dry degumming. Because palm oil has less gum, we usually use dry degumming. Dry degumming is to add phosphoric acid, stir well and let it react with the gum in crude palm oil, and then discharge the gum.

2. Deacidification: Deacidification can remove free fatty acids in palm oil. We generally use sodium hydroxide or high-temperature steam for deacidification. The deacidified oil tastes better, and the preservation.

3. Bleaching: Bleaching is to turn red crude palm oil into yellow. To get bleaching oil, we need to add white clay to absorb the pigments and impurities in the palm oil. Then, the white clay is separated by a leaf filter.

4. Deodorization: Deodorization can remove the peculiar smell in the oil, improve the smoke point of the oil, and improve the flavor of the palm oil. Generally, we inlet high-temperature steam into the palm oil, and use the method of distillation to volatilize the smelly substances in the palm oil.

After the above four processes, we can get bleaching and refining palm oil. Whether you already have your own palm oil press plant or plan to buy palm crude oil to refine, Henan Doing company can recommend the appropriate capacity and refining machine for you. If you have any needs, please contact us.

How to achieve maximum oil from sunflower seeds oil processing?

Depending on the same quantities raw materials and capacity, the more sunflower oil you can produce the more profits you will make for your sunflower oil plant. The different processing steps and machines can achieve maximum oil from sunflower seeds.

The biggest issue is the extraction methods of the sunflower seeds. There are two types technology of sunflower oil extraction, one is pressing plant, another is solvent extraction plant. The oil yield of them has 6% difference. Pressing plant uses the physical pressing method to press the oil from sunflower seeds, the oil residual ratio is 6-7%. The solvent extraction plant uses the chemical of solvent to extraction the oil, the oil residual ratio will be less than 1%. If the capacity is more than 20-30 tons per day, you can consider to use the solvent extraction method.

The second method which you can increase the oil yield is shelling. The shells will absorb some oil when pressing, so removing the shells of the sunflower seeds will decrease the oil residual ratio and increase the oil yield.

Except for the shelling, cooking will also help to extract more oil from the seeds. Cooking is adjusting the temperature and moisture to make the the sunflower seeds to reach the best conditions for extracting oil.

After cooking, it will go to the flaking processing. Flaking is making the seeds into small pieces, which will break down the inner structure of the sunflower seeds, and make is easier to extract oil.

Presser will also influence the oil yield. In the market, there are different models and capacities sunflower oil presser. The smaller capacity will be better to produce more oil. If is it possible can use several smaller presser to instead of the one big capacity.

By these measures you will achieve maximum oil yield for your sunflower oil plant.

The palm kernel crusher and separator from HenanDoing Company

Palm kernel oil (PKO) is a lucrative product from palm oil fruit. After palm oil is produced, the palm kernel remains. Processing the kernels provides an additional source of revenue. Traditionally, palm kernel nuts were cracked by hand. This tedious and inefficient method was then replaced by a palm kernel cracking machine, which could crack the nuts, but separation of nuts and shells still had to be done manually. This new technology palm kernel crusher and separator can crack the nut and then separate the nuts from the cracked shell. This is efficient and helps the processor avoid impurities.
 

Features of palm kernel crusher and separator
1. This palm kernel crusher and separator professional use for broken the hard shell of palm nut.
2. This palm kernel crusher and separator can be customized according to the customer requirements.
Palm kernel shell mainly contains fiber and cellulose, which can absorb oil and reduce oil yield. Therefore it is necessary to use palm kernel oil crusher and separator to get rid of palm kernel shell.
Background:
It is time-consuming and laborious to crush palm kernel shell and separate the shell and kernel manually. Manual method will cause palm shell to absorb more palm oil and reduce oil output. Therefore, palm kernel crusher and separator gradually replaced the manual method.、

Working Principle:
Palm kernel nuts are classified according to their size and are put into different crusher. After crushing, the mixture of palm kernel and palm kernel shell will be transported to separator, in which the cyclone will attract the shell to the shell outlet. The palm kernels are heavy and fall directly to the kernel outlet below. After separating, the palm kernel in shell rate is less than 5%, and the shell in kernel rate is also less than 5%.
Advantages:
(1)The shell of palm kernel was removed before pressing, which reduced the loss of palm kernel oil.
(2)High degree of automation, saving labor costs.
(3)High husking and separating rate, more than 95%.
(4)Integration of screening, crushing and separating， fully equipped.
 

Palm kernel crusher and separator plays an important role in improving palm kernel processing efficiency and quality. If you are interested in it, feel free to contact us for further details.

How does peanut oil refining machine work? What is the refining process of peanut oil?

The pressed peanut oil and the extracted peanut oil contain impurities, free fatty acids, waxes, unpleasant smell, pigments, a small amount of water, etc., which are harmful to human health and storage and affect the quality of peanut oil. Therefore, the peanut oil refining machine is very important.  Someone may ask how does the peanut oil refining machine work? What is the refining process of peanut oil? Let's discuss it in detail.

Refining principle of peanut oil refining machine:

 Peanut oil refining machine is mainly through hydration degumming, alkalization deacidification, clay adsorption decolorization, high temperature deodorization and other process to remove the impurities in crude peanut oil to get high quality cooking oil.

Refining process of peanut oil:

(1)Degumming:

  Peanut oil is mostly degummed by hydration, that is, hot water or electrolyte solutions such as dilute alkali, salt and phosphoric acid are added into peanut oil by using the hydrophilicity of colloidal impurities such as phospholipids to make the colloidal impurities absorb water and condense, and then settle and separate from the oil.

(2) Deacidification:

  Chemical deacidification is often used, that is, adding alkali liquor into peanut oil to neutralize with free fatty acids, so as to achieve the effect of deacidification. Deacidification is carried out in deacidification tower.

(3) Decolorizition:

  Generally, adsorption decolorization is a better choice for peanut crude oil. Adsorption decolorization is a process in which pigment and other impurities in peanut oil are adsorbed by clay with strong adsorption. After decolorization, the waste clay in crude oil needs to be filtered by a blade filter. The process of decolorization and filtration should be repeated 2-3 times to ensure good decolorization effect.

(4) Deodorization:

  Deodorization is a process of deodorization in crude oil by introducing direct steam under high temperature and high vacuum conditions. This process uses a deodorizer. Due to the high reaction temperature, the deodorization tower is mostly made of stainless steel.

Refining process of peanut oil

  After refining, you can get high quality peanut oil which meets the national standard and is edible. You can pump it into a tank, fill it and sell it.

Henan Glory Oils & Fats Engineering Co., Ltd is a comprehensive cooking oil refining machine manufacturing enterprise, integrating process design, technology research and development, manufacturing, sales and after-sales service. We can supply three types peanut oil refining machine for people to choose, they are: 1-20tpd batch type peanut oil refining machine, 20-50tpd semi- continuous peanut oil refining machine and 50-600tpd fully continuous peanut oil refining machine. No matter what kind of refining equipment you need, we can provide you with the suitable equipment.

The comparison of coconut oil chemical refining and physical refining technology

 No matter what kind of crude vegetable oil to be refined, there are two methods to choose: chemical refining technology and physical refining technology. For coconut oil, which refining technology is more suitable? Let's discuss it today.

The characteristic of coconut oil chemical refining technology:

Coconut oil chmical refining process flow chart

As the above picture shows that coconut oil chemical refining process contains four steps: degumming, neutralization, bleaching, deodorization.

Actually, there is no big difference between coconut oil and other crude vegetable oil chemical refining technology, such as soybean oil, canola oil. The only difference is that it doesn't need water degumming technology, because it has very low content of colloidal impurities, which is like crude palm oil. Another point worth to pay attention to is that coconut oil is very easily saponified, so if alkali refining process is improperly controlled, it will increase neutral oil loss. If you choose chemical refining technology to refine coconut oil, engineers' commissioning is very important, which can make sure that your coconut oil refinery plant have best effect, and the production consumption is low.

The characteristic of coconut oil physical refining technology:

Coconut oil physical refining process flow chart

The coconut oil physical refining process is a little different from chemical refining process. The deacidification process uses distillation method instead of neutralization method, and can obtain pure free fatty acid.

The biggest advantage of coconut oil physical refining technology is to avoid the environmental pollution of waste water produced in chemical refining process. Coconut oil physical refining technology uses distillation method to remove the free fatty acid and odors. You can get pure free fatty acid and sell them at good price. In addition, the crude coconut oil usually has high acid value, using physical refining technology can obtain better quality RBD coconut oil.

Though the coconut oil physical refining technology has better effect, its price is expensive, too. If your budget is not enough, small scale coconut oil chemical refining machine is also a good choice. Latter, you can also expand the production scale when having economic power.

How many tons of palm kernel does it need to produce 1 ton of palm kernel oil？

Generally speaking, the oil content of palm kernels is 50-55%. When the residual oil ratio is less than 7%, 0.43-0.48 tons of palm kernel oil can be obtained by pressing 1 ton of palm kernels. Conversely, one ton of palm kernel oil needs to press 2-2.3 tons of palm kernels.In theory, this should be the case, but there are other factors that can affect this result.Let's explore these factors together.

First of all, the oil content of palm kernels varies slightly depending on the place of origin.Therefore, the place of origin must be determined first.

The second factor is equipment. The quality of the equipment directly determines the oil output of palm kernels. Palm kernels are harder. If they are pressed with a conventional oil press, it will reduce the oil yield and cause equipment wear. Therefore, it is necessary to use a special oil press for pressing palm kernels. For small scale palm kernel oil pressing machine, the best-selling is 500kg/h palm kernel oil expeller, which is designed by our company to process palm kernels especially. As the palm kernel is harder, it requires higher hardness of the equipment and also requires stronger pressure. Therefore the pressure of the chamber is further increased, so as to achieve the efficiency of oil extraction and reduce the dry cake oil residue rate. Also the vulnerable parts are made of high-quality alloy steel, which can meet the hardness requirements and significantly improve the machine working life. Besides, our machine has been tested for many times, and the residual oil rate is less than 7%. The low residual oil rate guarantees the interests of customers.

Palm kernel oil pressing machine

The last is auxiliary equipment. In order to increase the oil yield, some auxiliary equipment needs to be used to make the palm kernel reach the best pressing state before pressing. Auxiliary equipment includes nut grading machine, cracker, crusher and cooker. Taking the cooker as an example, the cooker can adjust the temperature and moisture, increase the oil yield of palm kernels, improve the quality of oil and reduce equipment wear.

Palm kernel oil processing process

In order to increase the oil yield of palm kernels, all the above factors should be taken into consideration. If you want to know more about palm kernel oil press and auxiliary equipment, please contact Henan Glory Company. Our company is not only professional in making palm kernel oil machinery, but also in palm kernel oil mill plant, installation, technical consultation, etc..

How much oil can be extracted from 1kg soybean？

  The oil content of soybean is 18%-20%. If you process 1kg soybean, the amount of soybean oil you can get is different, based on different processing method. Using soybean pretreatment and pressing method, you will get about 130g soybean oil. If you use solvent extraction method to extract soybean oil, you will get about 190g soybean oil.

  You may be curious why the amount of soybean oil you can get is so different when using different technical processing? And what is the difference between the two technical processing methods?

  Soybean pretreatment and pressing method is using physical extrusion method. Use soybean oil press machine to extract oil from soybean which has been pretreated.Finally, the oil residue in the cakes is about 7%-8%.
Soybean oil olvent extraction method is acturally called soybean pretreatment and solvent extraction method, which is to use solvent to extract soybean oil from soybean that has been pretreated. The solvent often used is n-hexane, which can be recycled in soybean oil solvent extraction plant. Finally, the oil residue in soybean meal is less than 1%.

  So the amount of soybean oil you get depends on the residual oil rate of each technical processing method. Besides the difference, there is similarity of the two technical processing methods. It is soybean pretreatment section. Whatever using pressing or solvent extraction method, before processing, the soybean should be adjusted into the best condition to increase the oil yield.

  However, whether you can use solvent extraction method to extract soybean oil depends on how many tons soybeans you have  If the input capacity is large than 30 tons per day, soybean oil solvent extraction plant is the best choice for you. If the input capacity is less than 30 tons per day, soybean oil pressing plant is better.
  

  Henan Doing Mechanical Equipment Co., Ltd is a professional manufacturer of soybean oil extraction machine. And we can customized the soybean oil processing plant according to your requirement. Welcome to contact us.
