Edible Oilseed Pre-Treatment and Conditioning

Efficient design of equipment has direct influence on the quality and yields of oil and meals, as well as ensuring efficient functioning and maintenance of extraction equipment. Our government recognised in house R&D Centre has developed optimal treatment systems tailored to the individual characteristics of the oilseed to be processed.

These developments have been put to use in actual production conditions under the philosophy of “maximum profitability and quality at minimum cost”, making them one of the best available in the international market.

Our pretreatment equipment comprises efficient seed cleaning units, hullers, hull separators, cracking roller mills, crushers, flaking roller mills, automatic cookers, screw presses, expanders and oil clarification equipment.
pretreatment for oil processing The first stage in the raw material handling line is the removal of all dust, lints, sticks, stems, leaves, sand, stones and other impurities. Tramp iron pieces are removed by magnetic separators. When foreign particles like stones having the same size as the seeds need to be removed, special destoning machines are incorporated in the cleaning line.

Hulls are removed from the seeds to increase the protein content of the meal, to reduce its fibre content and to increase the effective capacity of the extraction equipment. Special decorticating and hull separating equipment is selected according to the type and nature of raw material to be decorticated. Low oil residue in the separated hulls is assured.

The organic impurities include the stem leaf, cord, chemical fibers, velveteen and their seeds. The inorganic impurities, however, sometimes mean soil, dinas and metal.The vegetable oil processing industry involves the extraction and processing of oils and fats from vegetable sources. The preparation of raw materials includes husking, cleaning, crushing, and conditioning.

Oil Frame Filter Press

The oil frame filter press is mainly used for filtering the crude oil pressed out by screw type oil press. The serial oil filter presses of frame typed oil filtering machine are ideal equipments for edible oil plant and individual oil processing house.

Frame Filter Press Oil frame filter press always be used as a oil purifier in the oil plants for edible oil or biodiesel. This model filter is suitable for filter crude oil and refined oil, and it is also can be used to filter bleaching oil in the refining workshop.

Crude (freshly extracted) oil contains moisture, and fiber, resins, colors etc. from the plant material, which make it darker and more opaque. These materials are removed by clarification – either by letting the oil stands undisturbed for a few days and then separating the upper layer, or by using an oil frame filter press. The oil is filtered through a cloth and heated briefly to 100°C to boil off any remaining traces of moisture. This is usually sufficient to meet the quality needs of customers and give a shelf life of several months when correctly packaged. However, the oil requires additional refining stages of de-gumming, neutralising and de-colouring to have a similar quality to commercially refined oils, and these stages are difficult to complete at a small scale.

Our oil frame filter press is characterized by convinient operation, stable technical effect, high capacity and low impurity.

What is Oilseed Processing?

Oilseed processing is the process of removing oil from oilseed.

Oilseed processing begins with the harvesting of oilseed on the farm where its grown, and continues through oilseed extraction where the oil in the oilseed is extracted, clarification, packaging, storage and shipping of the final oilseed oil.  Oilseed processing depends on several variables including the type of oilseed as well as the location, could be fully automated, or may require people to hand pick the oilseeds or nuts.
oilseed processing

Small-scale oilseed processing is of interest as a potential on-farm or community enterprise that can increase income and employment in rural areas. Many seeds, nuts and kernels contain oil, a vegetable oil, which can be used after it’s removed, in the following uses:

  • cooking
  • as an ingredient in other foods
  • as a nutritional supplement
  • as a raw material for the manufacture of soap, body and hair oils, detergents and paints

Some of these oils may also be used to replace certain petroleum-based lubricants and fuels. Small-scale oil extraction is more common in India, because there have more oilseeds to do oilseed processing.

Oil Refining Process Overview

Oil refining is the procedure of processing pure vegetable oils into edible bakery fats and oils, and the procedure contains three basic processes at the very least.

The first process is neutralization, which involves neutralizing the oil to remove free fatty acids by adding caustic soda. The oil and caustic soda mixture is heated up and stirred to induce a chemical reaction between the two that causes soap stock to form oil refinery plant . The mixture is then left for the soap stock to settle at the bottom of the neutraliser from where it is taken out into a soap pan.

The second process is bleaching, where the neutralized oil is drawn from the neutraliser to a bleacher. The bleaching process is done under a vacuum and it removes the colour from the oil with chemicals like carbon black and bleaching earth. The oil is once again heated up to a higher temperature by thermic fluid coils and stirred to speed up the chemical reaction.

The last process is called deodorizing, which is the process of removing the smell from the oil under high vacuum. The bleached oil and chemicals are separated from each other in a filter press and clean, colourless oil is drawn into the deodorizer. The clean oil is then heated through thermic fluid coils while live steam is injected into the oil through steam nozzles at the bottom of the deodorizer. The temperature of the oil is raised even higher and the odour of the oil is removed.

Refining palm oil includes an additional process named fractionation. This involves scientifically cooling the refined palm oil by chilling plant to separate palm olene and palm sterene. A crystallizing vessel with chilling pipe coils is used to cool the oil, which cause palm sterene crystals to form. Pure palm olene liquid is then filtered from the filter press and the palm sterene cake is retained click here to know more information.

Once these basic processes are complete, the oil goes to a cooler where water circulating coils reduce the heat until the oil is completely cooled. Again it goes to a second filter press where the completely refined, colourless and odourless oil is obtained and ready for packaging.

How To Invest In Oil Palm Production ?

Oil palm is native to West Africa. Nigeria used to be the world’s largest producer of oil palm before the crude oil boom era. Malaysia has now taken the leading position.  Oil palm plantation and allied industries is now the main stay of Malaysian economy. Malaysia came to Nigeria in the 70s to obtain oil palm seeds and seedlings. Oil palm can be used in various ways; the leaves are used in making brooms and as roofing materials (in the rural areas). The bark of the fond can be peeled and woven into baskets.

oil palm production

The main trunk can be split like sawn timbers and used as part of building materials. Palm wine can be obtained from oil palm, red palm oil is readily obtainable from the fresh fruit bunches. When the fruit is processed the residue obtained can be used as fuel (for cooking and fertilizer to improve soil nutrient).  Red palm oil is used in cooking, making soap, candle and margarine. Palm kernel oil can be extracted from the nut.
The residue obtainable in the process of palm kernel oil extraction otherwise called palm kernel cake is used as livestock feed. Palm kernel oil is used in vegetable oil and soap making.  Palm Kernel shells are also useful as energy source and industrial raw materials such as mosquito coils.

The uses to which oil palm can be made seem non exhaustive. This clearly indicates that investment made in the establishment of oil palm plantation is nothing but a wise one. The market is guaranteed for all the products of oil palm plantation in this era of global food crisis.

Technical information
oil palmTo establish oil palm plantation, it involves getting a good site where rich, well drained acidic soils are abundant. The soil should have adequate quantities of potassium, magnesium and nitrogen. Soil tests should therefore be carried out to determine the nutrient status of the land.It is usually better to use the early maturing variety called tenera, which bears fruits as from the fourth year.

Other requirements include seedlings procurement; this can be obtained from reputable nurseries. Prospective investors must engage the services of Agricultural experts in the course of establishing this project.Other cultural practices are planting, regular weeding, pruning and fertilizer application. Serious minded investors will be guided accordingly in the implementation of this project.

Income analysis
A matured plantation will start to give investor five 5 tons per hectare of red palm oil annually from the fourth year per hectare. 100 metric tons of oil can be obtained annually from 20 hectare plantation. A ton of red palm oil is a minimum of N150,000. Gross revenue of N15 million is obtained from red palm oil.

We can also get three metric tons of palm kernel per hectare. This gives us 60 tons from 20 hectares. This translates to annual income of N4.2 million. Total income realisable is about N19.2 million while the annual operating expense is put at N5.8 million.

This leaves us with net income N13.4 million annually for the investor for the rest of his/her live. There are still other sources of income such as palm fronds and palm kernel shells. Serious minded investors can be assisted in the realisation of this worth while investment.

What You Should Do Before the Oil Making at Home

Food making machines are developed at a high level now, small oil press for home use is one of them, as food safety issues and accidents happened from time to time, some people start to produce the food by themselves, including the edible oil, wheat flour, maize flour, nut powder, etc.

While now the processes of oil production in large oil mill plant are very complicated, there are more than a dozens of process to produce the edible oil with the modern quality standard. A lot of people might think that it is impossible to produce edible oil with the same level of quality in the oil mill plants, in fact it is not exactly true, oil making at home are usually at small quantities, that means the oilseeds quality and process is much more easier to control than in the oil mill plant, with the proper maintained small oil press and a clean oil production environment, you surely can have the fresh and safe edible oil produced at home, the following are some tips for you, it might not be perfect, you can have your own ideas later.

First, the oilseeds has to be processed to fit in the oil press, the hull and skin has to be removed, then the seed kernel shall be dried in certain degree for the proper water content; normally the frying part can be skipped for it is not easy to control at home, if you really want to do that, then you shall do it slowly and carefully. Generally speaking, no impurities in the oilseeds is the first and most important aspect to consider.

When you are processing different oilseeds, the method might be different, you can search for the oilseeds characteristics first for your new ideas on the oilseed preparation.

How To Produce Neem Oil for Plants

neem oilNeem oil has a weighty advantage to farmers, other people in other fields too can require it but in comparatively minor situations. It is a valuable insecticide and pesticide, fungal diseases on crops and chewing insects find themselves outside the garden boundaries when a farmer applies it. It as well protects people and animals from biting bugs. In some nations, especially in the western world, the most popular use of neem oil is the spraying on crops and animals for protection against pests, insects and fungal diseases.

Just like the production of castor oil requires investing in the best oil mill, so does the production of neem oil too. Therefore, you will need to choose the best brand name, one that is highly reputed in the market. While  the press plants could be going into business, the in thing today is the oil mill which is widely used for the commercial production of neem and castor oils, to name but just a few of them. If you are going into the small-scale production of oil, then you will need to invest in a full press mill where the seeds are double pressed for maximum production of oil

oil milling platIn the large-scale production of neem oil, the first step is the mechanical pressing for the extraction of initial oil. Later, the pre-pressed neem cake is sent to the solvent extraction chamber for further oil extraction. The choice of the oil mill depends on the budget and the business objective. Choosing the appropriate brand name is important so that you can also find the spare parts easily.

Helpful information on Coconut Oil Production

Coconut oil is extracted from the pressing the coconut fruit using many techniques. Coconut oil has many health benefits to the body. It is used as a moisturizer for the skin and the hair and it produces good results of the appearance. Coconut is also used as cooking oil since it has a heat tolerating component. There are many ways of extracting coconut oil and the major classification is dry and wet coconut oil production.

coconut oil plantThe dry coconut oil production entails removing the fleshy part from the fruit and letting it to dry. The drying options can either be using direct sunlight, heat from the fire or in the furnaces. The dried coconut material is known as copra. The copra is then pressed in the composition of other solvents to come up with coconut oil with high fiber and protein content. It is hard to split the protein from the oil and the unclean drying procedures make it unfit for consumption by humans. For further refinery to make the coconut oil usable by humans it is put through high temperatures and sieving processes. This processes uses sodium hydroxide to get rid of fatty acids in the coconut oil. Other chemicals like bleach agents are added in the filtration process. The outcome gives a different taste and aroma from the original coconut.
The success of the coconut oil production venture actually depends on the type of equipment that one uses. Luckily, there are many such in the market. There are some renowned brand names from China, which make easy work. Ok, at the start, this will require an initial investment of a hefty sum of money but once the production is under way, the result will be well worth it. When you invest in a good oil mill from a renowned company, they will send engineers to do the initial installation. You can also be assured of getting the spare parts easily whenever the need for them arises.

How to make a home oil press

The production of oil does not have to be done in an oil milling plant especially if the amount is minimal or the person going to use it does not want the extraction to be done using solvents or even pressure. When oil from a variety of seeds is extracted using solvents there may be some residue of the chemicals left in the oil which may be harmful to the health of those consuming it. It is for this reason that some people resort to making their own oil using a home oil press. This simple machine is used to produce oil from a variety of seeds through pressing them in ram or screw presses.
home oil pressmini home oil press machine
To be able to make homemade oil requires an oil press that can easily be constructed in the comfort of the home. The materials that are needed can be found locally from stores that auto parts and other stores as well. Some of the materials needed include metal cylinder, piston and a floor jack that weighs three tons. The bottom of the metal cylinder at the bottom is closed off using the piston, while the floor jack provides the pressure needed for the extraction of the oil from seeds.

For oil to be pressed from the ground seeds using the home oil press, they are placed in the metal cylinder which has holes drilled onto it at the bottom. The piston is then placed into the cylinder with a pipe welded onto it so that it fits into its centre with two other pipes fixed onto it for contraption and for the oil to flow through as well.  Finally, the floor jack is placed on the cylinder and then pumped using the hand so that the pressure produced pushes oil out the holes.

General features of an edible oil filling machine

Edible oil processing is mostly done at a refinery plant that eventually packs the oil that has been refined for sale. The process of edible oil production is quite extensive and begins from the preparation of seeds to the last step where the crude oil is refined. To be able to package edible oils properly, many oil milling plants have invested in an edible oil filling machine. The machine which is manufactured by a number of companies is essential in ensuring that the filling is done up to standard and there is no wastage through spillage.

edible oil filling machine The edible oil filling machines that have been made available by manufacturers are used to pack a variety of oils which are sometimes not even edible. However, for edible oils the oil is poured into containers such as metal containers, glass and plastic bottles. The features of an edible oil filling machine include diving nozzles that are used to dispense the oil into the containers with minimal spillage if any. The filling machines are also made of stainless steel which ensures that they do not rust as this may contaminate the oil that is being poured into various containers.

Oil Filling MachineThe filling lever which is adjustable depending on the size of the container is another feature found in edible oil filling machine. The lever is used to regulate the level at which the oil is to reach, and it is done automatically. In addition, a stopper arrangement for the bottles is also a feature found in filling machines which ensures that the containers are filled one at a time. Lastly, most of these edible oil filling machines are easy to operate after some training which is done by the company so as to ensure the filling process is always done well.
