Palm kernel cake is a high-fibre, medium-grade protein feed best suited to ruminants. [ 3 ] [ 4 ] Among other similar fodders , palm kernel cake is ranked a little higher than copra cake and cocoa pod husk, [ 5 ] but lower than fish meal and groundnut cake , especially in its protein value.
It is related to two other edible oils: palm oil, extracted from the fruit pulp of the oil palm, and coconut oil, extracted from the kernel of the coconut. [2] Palm kernel oil, palm oil, and coconut oil are three of the few highly saturated vegetable fats; these oils give the name to the 16-carbon saturated fatty acid palmitic acid that they ...
An expeller press is a screw-type machine that mainly presses oil seeds through a caged barrel-like cavity. Some other materials used with an expeller press include meat by-products, synthetic rubber and animal feeds. Raw materials enter one side of the press and waste products exit the other side.
Palm oil block showing the lighter color that results from boiling. Palm oil is an edible vegetable oil derived from the mesocarp (reddish pulp) of the fruit of oil palms. [1] The oil is used in food manufacturing, in beauty products, and as biofuel. Palm oil accounted for about 36% of global oils produced from oil crops in 2014. [2]
Palm oil formed the basis of soap products, such as Lever Brothers' (now Unilever) "Sunlight", and B. J. Johnson Company's (now Colgate-Palmolive) "Palmolive," [8] and by around 1870, palm oil constituted the primary export of some West African countries. [9] In 1780, Carl Wilhelm Scheele demonstrated that fats were derived from glycerol.
De Zoeker (The Seeker), an oil windmill in the Zaanse Schans, in the Netherlands. An oil mill is a grinding mill designed to crush or bruise oil-bearing seeds, such as linseed or peanuts, or other oil-rich vegetable material, such as olives or the fruit of the oil palm, which can then be pressed to extract vegetable oils, which may be used as foods or for cooking, as oleochemical feedstocks ...
Breaking it down to its simplest formulation, the process that oilseed presses carry out appears is quite simple. Oilseed presses essentially extrude or ‘press’ vegetable oil from oil-bearing seeds, which include soybean, sunflower, peanut, safflower, canola, sesame, niger, castor bean, linseed, mustard, coconut, olive, and oil palm.

The kernels are dried by agitating them in a layer 4–5 feet deep under the sun in a godown. The kernel is broken up to 6–7 mm size and crushed through an expeller; 8-9% oil is recovered from the seed, then the oil cake is processed by solvent extraction to yield the remaining oil from the oil cake.
