A Groundnut Peeler is an agricultural and food processing machine used to remove the outer skin (shell or red husk) from groundnuts (peanuts) after drying or roasting. It is commonly used in farms, small industries, and food processing units to improve the quality and appearance of groundnuts for consumption or further processing such as oil extraction or peanut butter production. The machine typically consists of a feeding hopper, peeling chamber, rubber rollers or abrasive surfaces, a blower or fan, a motor, and separate outlets for peeled nuts and husks.

In operation, dried or roasted groundnuts are fed into the hopper and directed into the peeling chamber. The motor drives the rollers or abrasive mechanism, which gently rubs and loosens the outer skins from the kernels without damaging them. As the peanuts pass through, the skins are detached. A blower then creates airflow to separate the lighter husks from the heavier peeled nuts—blowing the skins away while the clean kernels fall through a separate outlet. Some machines also include a grading system to separate broken and whole nuts. The process is fast, efficient, and helps produce clean, high-quality groundnuts suitable for consumption or further processing.
