Have you ever wondered how those delicious, crunchy, crispy peanuts are made in factories? Behind every perfectly coated peanut is a complete, crispy peanut production line — a highly automated system that turns raw peanuts into a ready-to-eat, marketable snack.
Let’s take a closer look at the main equipment and working principles of this line to understand how crispy peanuts are processed from start to finish.
Overview of the Crispy Peanut Production Line
This line integrates multiple machines — from roasting and peeling to coating, frying, and seasoning — ensuring consistent quality, high efficiency, and minimal labor requirements.
The crispy peanut production line is designed for mass production of coated peanuts, a popular snack in Asia, the Middle East, Russia, and beyond.
Crispy Peanut Processing Plant Working Process
Roasting – moisture reduction and flavor activation
The process begins with a peanut roasting machine, which evenly heats raw peanuts using hot air circulation. This step reduces the moisture content, enhances aroma, and prepares peanuts for easier peeling.
Temperature and time can be precisely controlled to maintain uniform roasting results.
Peeling – removing the red skin
Once roasted, peanuts are fed into a peanut peeling machine, where rubber rollers or friction blades gently remove the outer red skin. The peeled peanuts appear clean and smooth, ready for coating.
Automatic peeling ensures high efficiency and low breakage rates.
Coating – creating the crispy shell
The peanut coating machine (also known as a peanut coating pan) is the key to forming that signature crispy layer. Peanuts are rotated in a drum while a mixture of flour, starch, and seasonings is evenly sprayed.
Layer by layer, the coating builds up until each peanut is perfectly covered. This step determines the texture and crunchiness of the final product.
Swing roasting – perfecting the texture
Next, the coated peanuts enter a swing roasting oven, which uses continuous hot air to bake the coated surface until golden and crispy. The swing motion ensures that each peanut receives even heating, preventing burnt spots or uneven coloring.
This step locks in the crisp texture that defines high-quality coated peanuts.
Cooling – stabilizing the structure
After roasting, peanuts must cool quickly to maintain their shape and prevent sogginess. A cooling cart or cooling conveyor blows cold air to reduce the temperature uniformly, improving shelf stability and preserving crunchiness.
Seasoning – flavor enhancement
The cooled peanuts move into an octagonal seasoning machine, where flavor powders (such as BBQ, honey, spicy, or cheese) are evenly distributed. The octagonal design ensures all peanuts are tumbled gently, allowing seasoning to adhere perfectly to the surface.
Packaging – final presentation
Finally, the flavored peanuts are packed using an automatic granule packaging machine. This equipment handles accurate weighing, filling, and sealing — ensuring every bag maintains freshness, hygiene, and visual appeal for retail sales.
