Nut and Kernel Separation


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.

Palm Nut Fibre Separator

Palm Nut Fibre Separator

The mixture of nut and fibre is dried first and then separated from each other in depericarper (nut & fibre separator). It is essential to separate palm nuts from the fibres. As fibres is light in weight, they are carried away by air flow, while nuts are fall into a rotary drum. The separated fibres are used in the boiler as fuel, the super-heated steam is then used to drive turbines to generate electricity for the mill.

Nut Silo

Nut Silo.

The nuts are sent to nut silo to be dried and then cracked. By use of cracking machinery, the palm kernel will be recovered from the nuts. The nut shells are collected and feed into boiler with fibre.

Ripple Mills

Ripple MillsRipple Mills 2

Ripple mills is for cracking of palm nuts. The advantages of using ripple mills is that, up to 98% of cracking is achievable. It has high wear resistant and interchangeable rods that makes it have longer life span thus lower maintenance cost. It is easy to operate and the maintenance required is minimum. The installation is easy and have less power consumption.
