Frequently Asked Questions

What are the steps in groundnut processing?


Groundnut processing involves several key stages to achieve 99.99% purity and food-grade quality. The steps include raw material intake, pre-cleaning to remove dust and debris, de-stoning to eliminate heavy contaminants, shelling and dehulling to separate the kernel from the shell, polishing and grading based on size and density, optical sorting to remove defective nuts, optional seed treatment or coating, and final packaging for distribution.



How do you remove the skin from groundnuts?


The skin or husk of groundnuts is removed during the shelling and dehulling stages using specialized groundnut shelling machines. These machines apply controlled pressure and friction to crack the shells without damaging the kernels. Further skin removal can be achieved through blanching or polishing, depending on the desired product quality.



What is a groundnut shelling machine?


A groundnut shelling machine is a mechanical unit designed to efficiently remove the outer shell of peanuts or groundnuts. It uses rotating drums, screens, and air suction systems to separate the shell from the kernel with minimal breakage. MMCTECH offers shelling machines integrated into a fully automated processing line with SCADA and PLC control for precision and efficiency.



How are shelled peanuts processed?


After shelling, peanuts go through grading to sort them by size and density, followed by polishing to enhance their appearance. Optical color sorters remove discolored or damaged kernels. If required, peanuts can undergo seed treatment or coating for added value. The final step involves automated packaging into bags or bulk containers, making them ready for storage or market distribution.
