Small Palm Oil Mill Plant

Small palm oil mill plant mean a reduction in capacity, working capital and operating costs. However, it doesn’t necessarily mean large efficiency decrease. Small-scale mills are processing units that can handle a maximum capacity of 2 tones of fruit bunches that are freshly cut in a period of one hour. Processing units that process a minimum of 3 tones and a maximum of 8 tones of freshly cut palm fruit per hour are called as medium scale mills. Large industrial mills are the largest mills and can process 10 tones and more per hour.

How to Build A Small Palm Oil Mill

The following are some factors need to be considered before build a small palm oil mill:

Small mills are constructed in the local communities this is to ensure limited transportation of raw materials. Poor road networks in the rural areas affect transportation of raw materials from the farms to the processing plants. Placement of processing plants near the farms reduces postharvest losses that may occur through fruit spoilage.

The prime power mover should also be put into consideration. Most villages rely on diesel-powered engines as the main source of power. The diesel-powered engines may be used to produce electricity to run different operation units in the processing plant. The number of units of operation relies on the power sources to run them.

Process of Small Palm Oil Mill Plant

There is a wide range of techniques used for processing palm oil fruits into edible oil. These techniques are categorized according to the complexity degree of the machinery being used in the operational unit. This category includes use of traditional methods and industrial mills categorized as large industrial palm oil mills and medium scale mills and small scale mills. There has been adequate literature about various traditional technologies, large and medium scale processing mills. Limited information about the small-processing units has been shared. The following is some experiances in starting a small scale palm oil pressing plant.

01. Bunch Reception

Processing of palm oil fruits starts by bunch reception. Bunch reception involves receiving freshly cut fruits from the field. The fruits may be in form of bunches or at times loose fruits. At the bunch reception point the fruits are carefully emptied into wooden boxes which help in weighing on a weighing scale .The use of weighbridges make work easier and efficient especially if the fruits are carried in trucks and in large installations.

The fruit bunches received are then threshed manually by removing the spikelets which are fruit-laden from the bunch stem. The spikelets are cut from the bunch stem with a machete then the fruits are separated by hand.

02. Sterilization

Sterilization of the threshed fruits is done by cooking the fruits in water. This is mostly done in small-scale processing mills which can not generate their own steam. During the cooking process most of the water is absorbed by the whole bunches .While heating the bunches, high-pressure steam heating is recommended because it is reduces water loss. Sterilization using high-pressure system usually thresh the bunches after fruits are cooked. On the other hand, operations that are small scale, the fruits are threshed prior being cooked.

03. Digestion

Digestion of the fruit comes after sterilization. Digestion is a process involving rupture of cells that are responsible for bearing oil. The digester that is commonly used for this stage is coupled with a shaft enclosed in a cylindrical vessel that is steam heated. The shaft has stirring arms that ensure proper pounding of the fruit. Steam injections and heat insulations, which help in maintaining contents in the digesters during elevated temperatures are not fitted in small scale digesters due to maintenance and cost issues.

04. Oil Extracion (Small Palm Oil Screw Press)

Extraction of the oil is then done after digestion of the fruits. Extraction can be done using two methods that are the 'dry' method and 'wet' method. The dry method involves the use of mechanical presses while the wet method uses hot water, which leaches oil out.

05. Clarification

The process of clarification follows extraction. This process involves separation of the impurities from the pure oil. The extract is comprised of water, debris and other fibrous material. Wastewater is achieved from the clarifier as waste and is later led into a nearby sludge pit. In small mills the sludge that accumulates is not treated, it is collected in buckets and used as a herbicides to kill weeds around the area where processing takes place.

06. Storage

Storage of the processed oil is the final step of the process. In this step, the small scale mills pack the oil that has dried in used plastic drums and stored in warm temperature.

The final quality of palm oil manufactured by small palm oil mill is key especially when determining the price. The quality of palm oil extracted is influenced by different factors. Some of the factors affecting the composition and quality of palm oil may be genetic make up of the plant, environmental conditions, the technique of harvesting and transportation and fruit handling.

  • Please send me quotation of 30 ton per day palm oil mill plant.
  • Hi, dear, thanks for your inquiry about our product. Is your raw material kernel or fruit? Since there are little difference between its pressing process. So we can design for you accordingly.
  • Is it possible to have a complete palm oil  mill plant that an also refine the crude palm oil into deodorized edible oil and crack the nuts as well to produce palm kernel oil and lastly process the kernel cake into animal feed at the same time.how much will that cost and how long will it take your company to manufacture it.
  • Yes, it's turn-key project from seeds to edible oil. Pls kindly inform us more info, will design and quote for you accordingly.
  • We are willing to built palm oil mill plant 80ton per hour. For our plantation in West Kalimantan. Please advise.
  • Thanks for your inquiry. Please help to advise below information before quoting you the most suitable solution.
    1. Your raw material is palm friut, right?  And the capacity is 80TPH?
    2. May I know how many palm trees do you have in your plantation now? How do you handle the plam fruit before?
    3. Do you have any available factory to set up the plant now? How about the size and distance from the palm plantation? How about the water and electricity situation nearby?
  • I would like to visit your factory to arrange for a 20 ton daily capacity crude palm oil degumming and deodorizing plant.I live in the USA but this plant will be installed in Africa.So as soon as you can set up a date for me to visit your factory, I will be there.
  • Thanks for your enquiry to our products.
    As for your request, could you kindly advise the following questions
    1. which country does the project locate in Africa?
    2. As for refinery, it includes degumming, deacidification, decoloring and deodorization and fractionation process.
        Pls double confirm you just need degumming and deodorization process...?
    3. How many people and when will you come, we'll arrange for you accordingly soon.
    4. What's your contact info, such cell, skype, whatsapp... so we could talk directly.
