In the peanut deep-processing industry, peeling and cutting peanuts into half-kernels is a crucial step for factories producing peanut butter, roasted, coated peanuts, peanut snacks, and oil extraction products. One of the most efficient devices for this purpose is the peanut peeling and cutting machine.
But how does this machine remove red skin cleanly and split peanuts evenly into halves? Why is it much more stable and efficient than manual operation?
What Is the Main Function of a Peanut Peeling and Cutting Machine?
A Peanut peeling and cutting machine (also called a peanut half-splitting machine or a peanut skin-removing machine) performs two major tasks:
Peel the skin off the raw peanuts
Friction, centrifugal motion, and abrasion remove skins gently without breaking kernels.
Splits peanuts into uniform half kernels
A rotating cutting disc guarantees a standardized size suitable for further production.
Application fields:
Peanut butter production, bakery ingredients, deep-fried coated peanuts, oil extraction, food processing plants, and snack factories.
Working Principle of a Peanut Peeling and Cutting Machine
Feeding — peanuts enter the abrasive peeling chamber
Nuts fall into the friction area through the inlet. Abrasive rollers and belts rub the surface, loosening the skins without damaging kernels.
Peeling — red skins removed by centrifugal airflow
A built-in fan blows the loosened skin away instantly, leaving kernels clean and smooth for the next stage.
Half-splitting — knife disc cuts kernels into two halves
The cutting blades rotate at a stable speed. Peanuts are split naturally into halves, and the cutting angle keeps breakage low.
Grading — whole kernels and unpeeled nuts re-circulated
A screening system separates half kernels from incomplete materials, ensuring high yield and uniform quality.
Complete workflow:
Feeding → Abrasive peeling → Air separation → Blade cutting → Half-kernel output → Reprocessing if needed
Why Choose a Peanut Peeling and Cutting Machine Over Manual Work?
| Comparison | Manual Processing | Peanut Peeling and Cutting Machine |
|---|---|---|
| Capacity | Low | 100–2000 kg/h (customizable) |
| Peeling rate | Unstable | Up to 95% and efficiency |
| Half-kernel quality | Hard to control | Even size, low breakage |
| Labor cost | High | Up to 95% efficiency |
| Continuity | Easily affected | Stable continuous operation |
Mechanical processing is the trend — stable, fast, clean, and profitable.
