Palm kernel oil is a white to yellowish oil of vegetable origin which is solid at normal temperatures and is obtained from the kernels of the oil palm. Palm kernel oil is different from palm oil, which is obtained from the flesh of the fruit.
Four products namely palm kernel oil, palm kernel cake, palm kernel sludge and palm kernel shell which is used as a bio fuel can be gotten from palm kernel nuts. Palm kernel oil is processed to yield edible fats, soaps and candles and is used in the confectionery, pharmaceutical and perfume industries.
Firstly, the wet fiber and wet nut enter the cake breaker conveyor to be cracked, and mostly of the fiber should be separated by pneumatic fiber depericarper system. The nut, little fiber and big impurity will be further separated by the polishing drum. The separated nut should be sent to nut hopper through the pneumatic nut transport system, and then adopt the ripple mill to crack the nut, after cracking, most of the shell and kernel will be separated by cracked mixture separating system, and the rest of mixture of kernel & shell enter to the special clay bath separating system to separate them, after this processing, we could get pure kernel(The shell content in kernel <6%), which should be conveyed to the kernel silo to dry. After dried moisture as 7%, the kernel will be conveyed to kernel storage bin for storage, Usually the dry kernel’s capacity ratio is 4%. So it should be collected until enough quantity, and then be sent to the palm kernel oil mill, For the separated shell, it should be conveyed to shell temporary bin as the spare boiler fuel.
