Palm kernel expeller machines - to extract palm oil & palm kernel cake effectively

What is Palm Kernel Expeller?

Palm kernel expeller sometimes also referred as palm kernel cake (PKC) is a by-product obtained from the crushing and expelling of oil from the palm kernel via the mechanical process.

Palm kernel expeller is known to be an important ingredient in the formulation of animal feeds and is considered to be excellent for ruminats such as cows, horses, poultry and sheep. This by-product contains magnesium, iron, zinc protein, high fibre, good level of residual oil and is high in palmitic acid.

Production of Palm kernel cake or palm kernel expeller:

The production of palm kernel cake involves several steps including:

Kernel pre-treatment (cleaning)
Grinding or size reduction
Flaking
Steam Conditioning
Screw Pressing

During the screw pressing stage, the raw palm kernel oil is diverted for oil clarification to remove solid impurities. The residual palm kernel cake is cooled and stored. There are three variations in the process of palm kernel oil extraction i.e. direct screw-pressing, partial pre-treatment, and complete pre-treatment.

Direct screw-pressing

Some mills crush the palm kernels directly in the presses without doing any pre-treatment on the seeds. Double pressing is usually done in such cases to ensure efficient oil extraction. The screw-presses used normally are less than 10 tonnes per unit per day.

Partial pre-treatment

Prior to screw pressing, the kernels are first broken down to smaller fragments by grinding. In some cases, cooking of kernels is also done.

Complete pre-treatment

Complete pre-treatment includes cleaning, grinding, flaking and steam conditioning before screw pressing the palm kernels. Plants with larger capacities choose complete pre-treatment.

I am Virendra Verma writing on Seed Processing Machinery from last few years on regular basis to aware about Industrial Oil Mill Machinery Tools & Equipments to web users and define how they are important & beneficials for us & what’s role they play in our machinery Industry.

Solvent Extraction - procedures and steps involved in the process

What is Solvent Extraction?

Solvent Extraction, as the name suggests is a process to extract oil from oil bearing materials by means of a solvent. Generally, Hexane (a petroleum by-product) is used as the solvent.

What are Solvent Extraction Plants?

Solvent Extraction Plants are used to extract oil by using chemicals. These plants use cake as the raw material, which is obtained from the oil press section. An organic solvent is used to dissolve the cake's or seed's oil content after the process of dipping or spraying, which ensures that the oil content is in close contact with the feeding material. After this, the solvent is vaporized out and the oil is collected. In these plants, the vaporized solvent is recycled.

There are many Solvent Extraction Plants manufacturers, who use the quality assured materials and latest technology in the fabrication process. Generally, these plants are designed especially for extracting oil directly from oilseeds that contain less than 20% oil such as Soybean after the process of flaking. Pre-pressed or fully pressed seed cake that contain over 20% oil such as cotton seed, palm kernel, sunflower, copra, Castor, peanuts, and others.

Most of the edible oil manufacturers now-a-days use the horizontal extractors that operate on the principle of counter current, moving bed. It has varying height of bed and varying speed mechanism that allows absolute extraction by perfect penetration & percolation of the solvent.

Procedures followed in the solvent extraction process:

Dip oil-rich flake or pre-pressed cake into solvent
Dissolve vegetable oil into chemical solvent
Filter solid material
Evaporate oil mixed solvent to separate oil and solvent
Cool and recycle solvent
Further process oil and cake.

The best attribute of the solvent extraction plant is that it offers simple change-over of the process materials. These plants also find usage in the extraction of various useful solvents in assorted industries.

Salient features of the standard solvent extraction plants:

Available in solid - liquid and liquid - liquid extraction systems
Uses various solvents polar or non polar or a combination of both
Versatility to process all types of seeds, bran or oil cakes
