Palm Kernel Expeller (PKE)

Palm Kernel Expeller, An Introduction.

The inner palm kernel is where the Palm Kernel Expeller comes from. The inner nut, the kernel, is sent to the expeller factories where it is expelled twice to produce a higher quality oil, palmolein. The kernels are centrifugally cracked in a drum machine and milled. The residue left after oil extraction from palm kernels is Palm Kernel Expeller (PKE). Palm Kernal Expeller is a good animal feed.It can also be used as a biofuel in certain cases.


Palm Kernel Expeller is a brown powder, mostly with 1-5 mm size of the particles. Moisture of the product is on the level of 9-10%. Ash content is 3,7-4%. Chlorine is 0,15%. Sulphur 0,28% . Net calorific value is 16,8-17 GJ per mt. PKE is a good biomass: ash is rather low, it does not have strong smell, net calorific value is rather high. Big quantities of Palm Kernel Expeller has been sold to UK power stations where it was used mostly for co firing with coal.


How do we make it?

Palm kernels produced during the milling process of palm fruits of the oil palm (Elaeis Guineensis) contain approximately 50% oil that can be extracted commercially via two methods i.e. mechanical expression and solvent extraction. Palm Kernel Expeller (PKE) is the by-product of the oil extraction process. It is the residue from the extraction of kernel oil using mechanical screwpresses. The main usage of this product is as an ingredient for compounding animal feed. It has high fiber content and thus is usually used in foods for ruminants such as cattle. PKE is of vegetable source and every precaution shall be taken to avoid contact with material from animal origin. They pose no hazard to the health of human and animals.


A high quality source of energy which contains vast amount of Metabolisable Energy (ME) and Crude Fibre (CF) which is an excellent choice of animal feed. It is free of aflatoxin, heavy metals, toxic chemicals, dioxins and pesticides thus is safe for animal feeding.


High dry-matter content inherent in PKE discourages the growth of mirco organisms and optimizes growth performance.
