Palm fruit or palm kernel for edible oil has been processed in Africa for thousands of years, and the oil produced, highly colored and fragrant, is an essential ingredient in one of the traditional African cuisine. Mechanical extraction processes are suitable for both small, medium and large capacity operations. The basic steps are :
How are palm kernels processed?
An inbuilt stirrer is used to homogenize the solution. After separation, the kernels are wet and hence need to be dried before being sent to the pressing unit. For this, we use hot Air driers that run either on manual burning of firewood / shells in a furnace or using a steam boiler. The palm kernels are subjected to cleaning in a seed cleaner.
How does a palm kernel oil expeller work?
The cleaned Kernels are fed to a palm kernel oil expeller machine, which consists of a main shaft and worms, which rotates within a stationary perforated cylinder called a cage or barrel. As the main shaft turns, there is a decrease in volume resulting in pressure in the cage.
What are the basic steps in palm oil extraction?
The basic steps are : Palm Nut is one of the byproduct of Palm Oil Extraction Plants. These Nuts comprise of about 50% Palm Kernel. Proper Separation Technique is necessary to recover the kernels from these nuts. Ripple Mills are used to crack the Palm nuts.
