Screw oil pressing plant is suitable for both small and large palm kernel oil extraction plant. Screw oil pressing is a kind of mechanical oil extraction process which mainly includes:

The following the three different processes of palm kernle oil extraction plant.

There are three variations of mechanical kernel oil extracting procedure: direct screw pressing, partial pretreatment and complete pretreatment.

• Direct screw-pressing: Some small palm kernel oil mills is designed without any pre-treatment machines. The kernel is fed directly into the oil presses, crushed and compressed at the same time in the oil pressing machine. Double pressing is suggested to achieve higher oil extraction rate. Direct screw-pressing is suitable for small scale oil mill with capacity less than 10 tonnes per day.
• Partial pre-treatment: The kernels are crushed to small fragments before oil expelling. Cooking is also carried out in some cases.
• Complete pre-treatment: The full pre-treatment processes including cleaning, crushing, flaking and cooking are carried out before oil pressing. Large oil mill plant with capacities between 50 ~ 500 tonnes per day choose this kind of kernel oil processing procedure. Palm kernel oil combined with fresh palm oil mill plant adopts complete pretreatment procedure.

 Kernel Pre-treatment Section

The pretreatment section greatly affect the oil extraction efficiency and production cost. Before feeding into oil expeller (oil press), the palm kernels must be cleaning to remove impurities, otherwise they may damage the expeller, increase maintenance costs and reduce the quality of final oil product.

• Magnetic separator is used to remove metal debris;
• Vibrating screen is used to remove stones and sand;
• Break roller or winging hammer grinder is used to break the palm kernels into small pieces.
• Flaking machine is used to pressing the kernel fragments into flakes (0.25 to 0.4 mm thick).
• Cooker is used to adjust the moisture content of the palm kernel flakers to optimum level through steam conditioning. Besides, cooking process can also help reducing viscosity of oil, rupturing cell walls, coagulating the protein and facilitating separation of oil from protein materials. In the palm kernel oil pressing process, the meals are generally cooked to a moisture content of 3 % at 104-110°C.

 Screw-pressing Section

Oil expeller or screw press is the standard oil processing machine in the modern oil milling industry worldwide.

After properly pretreatment, the meal is then fed into palm kernel oil press (screw press), which is mainly composed of a revolving worm and a stationary perforated cylinder called barrel or cage. With the worm revolving, the meal is forced through the cage. The volume axially displaced by the worm diminishes from the feeding end to the discharge end, thus compressing the meal as it passes through the barrel. While the palm kernel expeller or cake is discharged from an annular orifice, the expelled oil will flow out from the barrel of screw oil press. For cold oil pressing process, a circulating water system is added to cool the worm-shaft and manufacturer high quality cold pressing oil product.

 Oil Clarification Section

The expelled oil discharged from the palm kernel oil press is then drained to a reservoir. The crude palm kernel oil inevitably contains unwanted impurities and foots, which must be removed to produce clear oil prior to storage.

• Revolving coarse screen or decanter is used to remove large solid impurities;
• Filter press is used to remove the remaining solids and fines;

Palm kernel is an important kind of by-product from palm oil extraction plant. About 45%~48% of palm nut is kernel. The kernels contain about 47%~50% by weight of oil. Palm kernel oil is quite different from palm oil in both characteristics and properties. However, it is more similar to coconut oil.

Full pressing, solvent extraction and pre-pressing solvent extraction is the three main oil extraction methods of palm kernel.

 Mechanical Oil Extraction Plant (full pressing)

Basic Section

• Palm Kernel Crushing
• Cooking
• Oil Pressing (expelling)
• Oil Filtering (crude palm kernel oil)

Full pressing extraction is also called single pressing, which is a physical extraction method that squeezing oil out under high pressure by use of mechanical screw oil press. The typical process of screw oil pressing plant is: palm kernel crushing, flaking, steam conditioning, mechanical oil expelling and oil filtering. Production cost depends mainly on mechanical wear and tear, electricity and maintenance expenses. Below is some of our Palm Kernel Oil Pressing projects.

Small Oil Mill Plant

Large Oil Mill Plant

Full pressing method is suitable for both small and large palm kernel oil mill plant, while solvent extraction method is generally applied to large scale oil mill plant. If you are planning to start palm kernel oil extract business, ensure your capital investment and your daily capacity before deciding the oil production process.

 Palm Kernel Solvent Extraction Plant

Basic Section

• Crushing
• Solvent Extraction
• Separating the solvent from miscella
• Separating solvent from wet meal
• Recycling of solvent

Solvent extraction plant separate the oil by mixing solvent in the material. Production cost depends mainly on solvent loss and energy used in solvent recovery. Compared with screw pressing, the oil recovery of solvent extraction plant is more complete.

 Pre-pressing & Solvent Extraction Plant

Pre-pressing & solvent extraction is another popular palm kernel oil production method.

After oil pressing or extracting, the oil then requires clarification in a filter press or by sedimentation. To ensure premium quality of final oil and by-products, palm oil mill should have strict quality control from fresh palm bunch processing to kernel oil extraction. Build palm kernel oil extraction plant with professional oil production process is the very first step to the success of your business. QI’E Group offer turnkey palm oil mill plant solutions from design, manufacture to installation, with competitive price.

Palm Kernel Oil Extraction

Generally, palm kernel extraction is separated from palm oil extraction. Most small and medium palm oil mills are not designed with palm kernel processing unit, but selling the kernel to other oilseeds extraction plant (such as copra, shea nuts, cottonseeds, coconut seeds, rapeseed, groundnuts and so on).

Palm kernel production in increasing steadily over the years. Both full press extraction and solvent extraction is available for palm kernel oil extraction plant.

Processing of Refined Palm Oil or Kernel Oil: To get high grade oil products, the crude palm oil can be further processed in palm oil refinery equipment.
The small scale palm oil refining plant makes an appealing business venture for investors and the like looking into creating palm oil processing business. It has proved rather advantageous in the booming market of palm oil production.

The Prospects of Small Scale Palm Oil Refinery

Our oil refining equipment unit for small scale production has all the bells and whistles including decreased land usage requirements and investment capital. Due to the small size of the equipment set, it is also easy to install and maintain. There are several types of crude oils you can choose to work with including palm oil (CPO), palm kernel oil (PKO) and other types of vegetable oil such as sunflower oil, fish oil, peanut oil, etc.

Crude Palm Oil: Each fresh fruit bunches (FFBs) consist many of these individual fruits. Crude palm oil is extracted from the flesh of these small fruits. The central nut or kernel can be separated and applied for extracting palm kernel oil.

Palm Kernel Oil: The palm kernel getting from the extraction of palm oil will be collected for making palm kernel oil. Palm kernel expeller or cake is the main by-product of palm kernel processing line.

Refining Process of Crude Palm Oil (3 Types)

You have the opportunity to carefully select which type refining process you want to specialize in. There are three common types of edible oil refining process: batch oil, semi-continuous oil, and continuous oil. Each type of refining process can determine the exact size and detailing process of the refinery plant.

Batch Oil Refining Process (1~30 ton/day)

This line of an oil refinery is perfect as a mini or small-scale palm oil mill plant. It requires low investment capital and a smaller occupation of land. You are able to refine almost every type of crude edible oil. The primary refinery process includes three stages which are de-gumming, neutralizing, bleaching, and deodorizing. This process eliminates all the impurities which make the oil inedible.

The refining process also includes making the oil palatable and rancid-resistant if and when it is stored for long periods of time. Batch oil refining holds a capacity of 1TPT to 30TPD.

Semi-Continuous Oil Refining Process (10~50 ton/day)

This line is suitable for medium-scale palm oil refining factory which are efficient in accommodating clients requests. You are able to refine different types of crude oils as well as plant and animal oils. It has a capacity of 10TPD to 50TPD.

Continuous Oil Refining Process (over 30 ton/day)

This line is specifically for large-scale palm oil refinery. It operates automatically with the refinement of the oils with the utmost efficacy. lts daily capacity stands at over 30TPD.

Palm Oil Fractionation

To separate solid phases (Stearine) and liquid phases (Olein), the refined palm oil should go through fractionation process. It is achieved by thermo-mechanical means.

Setting up a palm oil mill plant isn’t easy because a lot of factors such as accessibility and equipment have to be considered. An interesting thing about the global palm oil market is that it needs mini and small palm oil mill plants in order for its marketing operations to be successful.

Normally, a mini scale plant usually produces between 1-10 tonnes of palm oil daily while a small scale plant can process between 10-20 tonnes per day. If you are wondering how a palm oil factory can be set up and how the red palm oil is produced, below is a comprehensive information guide of how a small scale palm oil processing plant can be set up and the production processes involved.

How to Start Small Palm Oil Mill Business?

You need to search for the right location with ample space. A suitable location should be conveniently located near the palm fruit farms because you need a constant and fresh supply of Fresh Fruit Bunches i.e. the FFB. The location should be big and wide enough to perfectly accommodate many trucks which will be offloading fruits. A bigger space is also essential in the processing because some stages have to be done by hands manually and there has to be enough space for manual workers.

Main Equipment for Small Palm Oil Milling Plant
*Palm Cooking and Sterilizing Pot
*Palm Fruits Thresher
*Palm Fruits Oil Expeller
Most manufacturing processes require water and the processing of palm oil isn’t an exception. The palm oil mill plant should have a constant supply of steaming or boiling water that will be used during sterilization. Also, the surrounding environment has to be clean. If there is no access to treated water, the best alternative is to use borehole water which is cheaper and reliable.

Equipment Required in Small Palm Oil Extraction Mill

The most important equipment that is required in the production of palm oil is the palm oil expeller press or palm oil milling machine. The whole production process revolves around the extraction machine and this include sterilization, threshing, sterilizingas well as oil clarification. However, oil milling machines vary a lot depending on how the plant is going to be mechanized. For Instance, your palm oil milling machine doesn’t need a thresher if the threshing process is going to be done manually by laborers. But the good thing about mechanizing all the processes is that it helps to save time and to improve the plant’s hygiene by reducing the amount of wastes. Machines found in mills are like the palm fruit threshing machine, boiler, digesting machine, conveyor, screw oil press, oil filter and dryer.

When it comes to workers in the palm oil processing factory, if they are not experienced for the job then they have to be first trained on how to handle and operate different machines. However, manual laborers such as those who are responsible for offloading fruit bunches don’t even need extensive training but the plant may need professional members of staff such as a mechanical engineer who will be responsible for maintaining the mill, a chemical engineer responsible for testing and evaluating the oil among others.

* Final Product: Red Palm Oil
* Processing Flow: Palm Fruit Threshing, Digesting & Sterilizing, Oil Pressing, Oil Filtering, Crude Red Palm Oil
* Production Capacity: 300-400 kg/h (5-10 ton/day)
* Floor Space: 15m X 6m X 5m
Main Equipment Included: Palm Fruit Thresher, Digester (include boiler and 4 baskets), Conveying Machine, Palm Oil Press, Oil Storage Tank (with electric heating system) and Plate Filter
For mini palm oil mill plant with 1~10 ton per day production output, the processing flow is relatively simple, including threshing, digesting and sterilizing, oil pressing and oil filtering. One of the reasons why small scale palm oil mill are very common in the global market including Indonesia and Nigeria is that they are affordable and they are enough to produce sufficient amounts of palm oil for local business.

Equipment List for 10TPD Mini Palm Oil Milling Process

For 1-10 ton per day palm oil production, the crane is not equipped in most cases. The crane is used for lifting the palm fruits. In mini scale palm milling factory, this job usually done manually. View the photos below to see what the complete equipment looks like.

A mini production of palm oil mill basically includes belt conveyor, palm fruit thresher, screw conveyor, palm oil press, oil tank, oil filter and oil pump. Attention that not all equipment is necessary except palm oil press and filter. The equipment selection is based on your budget and business plan.

Palm oil mill plant involves the following five processing steps:

• Fruit Reception: Initially, the palm fruit bunch is weighed and offloaded from trucks. Note that the fruits have to be weighed in order to calculate the purchasing costs. The bunches have to be carefully offloaded from the trucks because if they are mishandled their quality may significantly decrease and this will have a negative effect on the final product. Poorly handled palm fruits have high acid levels which not only interfere with the taste but also increase the cost of production because the acid levels have to be decreased to a certain minimum amount.
• Threshing and Sterilizing: After that, the fruits undergo a process called Threshing where they are cut off from the bunch that holds them and they are put in boiling water with very high temperatures in order to “loosen” them. This process is what is known as — Sterilization by Pressurized Cooking. For starters, the threshing process can also be done manually to lower investment cost.
• Palm Oil Extraction: The third step is the extraction of the palm oil in screw palm oil pressing machine. This is step marks the peak of processing and the oil is extracted from the fruits by pulp pressing.
• Oil Filtering: The extracted oil is then Filtered and Purified in order to remove dirt and other remains such as water and fruit shells. After the red palm oil is purified, they can be stored in barrels or gallons before they are transported to the market.

In addition, it has the advantages of low brown core crushing rate, low residual oil of cake residue, no special requirements on raw material moisture content, excellent manufacturing process, compact structure, large output, stable and reliable operation, low maintenance and durability.

Start Your Own Palm Oil Extraction Business

Palm oil extraction business is now a relatively popular and lucrative project, especially in Nigeria, Liberia, Ivory Coast, Cameroon, Malaysia, Indonesia and other countries and regions. Screw palm oil pressing machine is widely used in small and large scale palm oil extraction plant. Why people tend to choose screw palm oil expeller press? The design of palm oil press machine is scientific and has higher oil extraction rate. And, the operation is relatively easy. So, palm oil press is popular in the market. However, the palm oil press machine will definitely calculate dust and residues over time. Then, cleaning can’t be overlooked. Here listed some tips on palm oil press machine cleaning.

Set up a small palm oil milling line with capacity ranging from 1 ton/day to 20 ton/day

Small scale palm oil mill plant generally refers to the palm oil processing production with the capacity below 20 ton per day. We have two small palm fruit processing solutions for your! One is mini palm oil mill plant for 1~10 ton/day factory, and the other one is 10~20 ton/day palm oil milling plant for small and medium-sized factory.

The main equipment for small palm oil mill is palm fruits cooking and sterilizing tank, FFB Stripper and screw palm oil press machine. Click the link to see more details of the related palm processing machines.

Small Scale Crude Palm Oil Milling Process

The main processing flow includes Palm Fruits, Threshing, Digesting, Pressing and Filtering. The basic processing section is shown as below:

Oil pressing plant from palm fruit basically includes: fruit threshing, sterilizing / digesting, oil pressing and filtering. Among all these processing sections, oil pressing and filtering must be done by professional facilities (palm oil extractor and oil filter press), while the other sections can be selected depending on your needs and financial status. It is certainly that a complete palm oil mill has higher automatic degree and needs fewer labor. Only 2~3 worker is needed to run the whole line. Besides, it can also avoid the unstable material feeding caused by manual control.

Process Design of Small Palm Oil Factory

If you are planning to run a small palm oil making factory, here is the factory layout design for your reference:

What output of palm oil mill do I need?

For most first-time palm oil mill businessmen, they have no idea about yield. So here we offer a way to caculate the production output you might need for your business plan. Palm oil is made from palm fruit or palm kernel. But whatever you want to make, the following calculation methods are all applicable.

There are about 140 palm trees planted per hectare land, and about 20 tons fresh fruits can be produced per tree per year.
In most cases, 12.5% of orchard output are defined as the maximum palm fruit consumption each month.
The producing time should be caculated according to 25 days each month and 20 hours one day.
Example: With 2000 hectares plantation, the production output of palm oil mill you need to build is:
2000 x 20 x 12.5% / 25 / 20 = 10 ton/hour

After palm oil pressing process, solids parts (mixtures of palm fibre and nuts) will be discharged out of the screw press. In palm kernel recovery plant, the nuts and fibre will be separated by physical method. The fibre are burned in steam boiler as biomass fuel. The super-heated steam is then used to drive turbines to generate electricity for the to the complete palm oil extraction plant. The nuts are send to crushing system to remove the shell. Palm kernel is another by-product of palm oil mill, which can be further processed in palm kernel processing plant to extract palm kernel oil, while the shells are sold as fuel to other industries.

Palm Kernel Recovery System

After palm oil extraction, the nuts and fiber are recovered from the mash. The mixture of nut and fiber is dried first and then separated from each other in depericarper (nut & fibre separator). As fibers is light in weight, they are carried away by air flow, while nuts are fall into a rotary drum. The separated fibers are used in the boiler as fuel. The nuts are sent to nut silo. By use of cracking machinery, the palm kernel will be recovered from the nuts. The nut shells are collected and feed into boiler with fiber. The kernels are further processed in palm kernel oil extraction plant to produce palm kernel oil (PKO) and palm kernel cake (PKC).

The rate of FFA increase is much faster in broken kernels. So try to keep the kernel breakage as low as possible during the nut crushing processes.

Main section and main machines of 1-5tph complete set palm oil processing machine:

Palm fruit reception station:

Used for loading palm fruit brunch from plantation,transport to sterilizer. Reception station adopt steel structure and concrete structure. Save equipment cost and construction cost.Have hydraulic control system, hydraulic door open/off automatic achieve continuous operation. Reduce operator, operate more easily and improve work efficiency.

Palm fruit station:

In small scale palm oil extraction process, the vertical palm fruit sterilizer is used. The vertical palm fruit sterilizer uses direct steam to process palm fruit, which can reduce activity of the enzyme,prevent the rancidity, ensure the good quality of the crude oil. At the same time, it is good for the threshing process.

Palm fruit threshing station:

Palm fruit thresher is used for separate empty fruit bunch and palm fruit. According to the different production scale of palm oil mill plant, we can provide different types of palm fruit thresher machine to meet the production needs, like: simply type palm fruit thresher mahcine and drum type palm fruit thresher machine. In the actual production process of palm oil,Usually we have a spare one, in case one of them not work. When the sterilization process is over, sterilized palm fruit will be convey to next station. The empty fruit bunch came from palm fruit thresher will be conveyed to outside, which can be used as fuel for palm oil mill.

Palm fruit digesting &  station:

Pressing station in 1-5tph new technology palm oil processing machine is include digestor and oil presser.

Sterilized palm fruit will be conveyed to palm fruit digestor.There are blades in digestor, blades will be rolling by motor which is on the top of digestor. Palm fruit peel can be crushed by blades, besides we will fill the steam in digestor for heating. Palm fruit pulp cell can be destroyed under the high temperature condition, after that the palm pulp will be sent to double screw palm oil presser to squeeze out most of palm oil.

Crude palm oil clarification station:

A mixture of oil, water, and solids from the bunch fibres is delivered from the palm oil digesting & pressing station to a clarification tank of palm oil mill equipment machinery. In the conventional process, separation of the oil from the rest of the liquor is achieved by settling tanks based on gravity. The mixture containing the crude oil is diluted with hot water to reduce its viscosity. A vibrating screen helps remove some of the solids. The oil mixture is heated to 85-90°C and allowed to separate in the clarification tank. A settling time of 1-3 h is acceptable. Oil from the top is skimmed off and purified in the centrifuge prior to drying in vacuum dryer. The final crude palm oil is then cooled and stored. The lower layer from the clarification tank is sent to the centrifugal separator where the remaining oil is recovered. The oil is dried in vacuum dryers, cooled and sent to storage tanks.

QI’E Machinery provides a range of palm oil making machines to extract oil from fresh fruit bunches of oil palm. The following is the typical palm oil manufacturing process which might be useful for new investors of palm oil production business.

Main Machinery for Making Palm Oil: Steriliser, digester, stripper machine, screw press, nut/fiber separator and so on.

The manufacture of crude palm oil involves a series of processes starting with harvesting fresh fruit bunches from the plantations and ending with crude palm oil storage. Through sterilizing, threshing, mashing and expelling, crude palm oil will be pressed out in palm oil pressing machine (screw oil press). Each station of palm oil mill uses different methods and machines. After purifying and refining, the refined palm oil can be exported as a popular kind of healthy and edible oil. Browse through the details of palm oil manufacturing in the following:

Plam Fruit Harvesting Process

The initial process in palm oil mill is reaping the palm fruit bunches.

Sterilizing Station

Through fruit reception system (left of the above photos), the palm fruit bunches will be transported to the next process – Sterilizing Station.

The disinfection process utilizes steam or water to sterilize the fresh palm fruits. This process likewise stops enzymatic responses that prompt oxidation and upsets the cells which are found in the mesocarp, so that to improve the oil extraction efficiency and final oil product quality. Dry sterilizing means roasting or smoking the fruits, while wet process means boiling or steaming the fruits. If choose dry process, the palm fruits are separated first, and then sterilized. If use wet process, the fruits are sterilized before threshing.

Threshing Station

Digesting Station

Before extracting oil, the palm fruits need to be crushed in digester machines. To augment oil yield, the fruit pulp is also warmed in this process. The mesocarp and nuts can be squeezed together in palm oil making/pressing machine. But if you plan to make Grade A Palm Oil, the palm nut/kernel should be removed before oil pressing section.

Oil Pressing Station

The pulp is then pressed, which bursts the oil-containing cells, releasing the palm oil. There are several types of oil making machines that may be used to press the fruit pulp, including manual presses, hydraulic presses, and screw presses. The screw press is the most commonly used palm oil making machine in both small and large scale palm oil manufacturing plant due to its high oil extraction rate.

Palm Oil Clarification Station

The purpose of clarification in palm oil manufacturing process is to remove impurities. The final crude palm oil will be storage in bulk in a tank.

Palm Kernel Recovery Plant

After palm oil expelling, the solids parts discharged from the screw press is mixture of fiber and nuts. In palm kernel recovery plant, the nuts and fiber are separated by physical means. The nuts are sent to palm kernel crushing and solvent extraction plant to make palm kernel oil, while the fiber is used as biomass fuel in boiler on-site.
