Experimental studies of some properties influencing cracking and separation of palm kernel from the shell was conducted in a palm kernel dual processing machine. A mechanical cracking cum ...
Abstract. The separation of palm kernel from the shell is an important process in the recovery of the kernel for use in vegetable oil production. The inherent …
The separation of shell from kernel of two varieties of oil palm in Nigeria was investigated in a laboratory inclined plane separator. Four angles of projection of 25, 30, 35, 40 and 45˚were45˚were used and three structural surfaces namely mild steel, galvanised steel and plywood were used for the separation experiment.
Processing of palm kernels into palm kernel oil involves the cracking of palm nuts, separation of the palm kernel shells from the cracked mixture (Kernels and Shells), washing, cleaning, crushing ...
Palm kernel shells were used as lightweight coarse aggregate in PKSC and granite was used as aggregates for the normal concrete. The study was conducted in accordance with the British Standards ...

The relative density of palm kernel is about 1.07 and that of the shell ranges from 1.15 to 1.20. Clay- bath and hydro-cyclones are two methods devised for cracked mixture separations based on ...
Adewale and Koya (2014) evaluated a rotary drum separator for the dry mixture of palm kernel and shell. Ojolo et al., (2015) developed a variable size nut cracker.
Ripple Mills are used to crack the Palm nuts. The nuts enter from top of the mill and are impacted several times between the stationary plates and turning rotor. The impact from the rotor cracks the nuts. The output from the Ripple Mill is a mixture of kernels and Shells. After cracking, next step is the separation of Palm Kernels and Shells.
Fig. 1. Top producers of palm oil in thousand metric tonnes in 2021/2022 ( Shahbandeh, 2022 ). Due to the processing of palm oil from the palm fruits, high …
A dry separation system is used to separate a mixture of kernels and shells (cracked mixture) derived from the oil palm nuts after cracking. The dry separation system …
material [3]. Removal of palm kernel from its shell basically, involves cracking and separation processes. The separation of palm kernels from the shells is an important process in the recovery of the kernels for extraction of PKO. The technique for this separation is of two types: the wet and the dry methods. The dry
of the kernels and shells in the sample were separately measured. The percentage weight or volume of the kernel or shell fraction was then calculated using the following equations 6 and 7: PW f = (W f
Adejuyigbe et al. [8] designed an improved palm kernel shelling and sorting machine which can be used to crack various sizes of palm kernel with an incorporated sorting unit for separation. The ...
3.1.4 Digestion of the fruit. Digestion is the process of releasing the palm oil in the fruit through the rupture or breaking down of the oil-bearing cells. The digester commonly used consists of a steam-heated cylindrical vessel fitted with a central rotating shaft carrying a number of beater (stirring) arms.
2. To construct the palm kernel cracking machine 3. To evaluate the performance of the palm kernel cracker 1.4 Justification of the study This project work seeks to proffer solution to the teeming population of local palm kernel and medium scale industries involved in palm kernel business in their quest for a convenient,
kernels. The kernels were then cracked with a palm kernel cracking machine available at the College of Engineering of the University. The moisture content of the shell and kernel were determined by oven drying method and was found to be 4.5% and 5.0% w.b. for dura shell and kernel while for tenera it was 5.1% and 4.5%. w.b. respectively.
The kernel purity, kernel recovery, shell purity, shell recovery and separation efficiencies of improved palm kernel dual processing machine are …
... The evaluation parameters include kernel purity, shell purity, kernel recovery, shell recovery and separation efficiencies. …
The conventional separation system for the recovery of palm kernel from its palm shell–kernel mixture using water as process media generates a considerable amount of waste effluent that harms the environment. The aim of this study is to develop a dry separation process for the recovery of palm kernel by using winnowing columns. A …
Based on relevant physical properties of palm kernels and shells, a separator was designed to remove the palm kernels from the shells. The separator has two sections: one to remove and collect the ...
Kernel Oil (PKO) leaving the palm kernel meal as residue, is a significant step that usually affects the quality of thekernel. Hence, thepreservation of this fragile kernel embedded in the palm nut is very important and depends, among other things, on efficient nut-cracking, which enhances effective kernel-shell separation as well as the ...
hydro-cyclones in palm nut cracked-mixture separation to small–scale oil palm processing industry especially in the rural areas where grid electricity is absent. Specifically, this study sets out to: Critically analyze the innovations already available for the separation of cracked mixture containing shells and kernels.
The physical characteristics of palm kernel that need to be taken into account include: Size of palm kernel nut, hell and kernel, mass of palm kernel and coefficient of friction for shell and kernel with respect to steel (Gbadamosi [9], Manuwa, S. I. [10], Olakanmi et al. [11]). 2.2 Size of Palm Kernel Nut, Shell and Kernel
Plate 1: Experimental facility for investigating the dispatch angle of kernel and shell in a rotating drum Dried palm nuts (at 13.4% moisture content, wet basis) were cracked, and the mixture was screened using a set of standard BS 410 sieves (Endecotts Ltd., London), to obtain kernels and shells of the same size grade for the
The manual method of palm nut processing is the traditional way of cracking and separating palm kernel. It is a typical business venture for local youths and old women in the …
