Wet type peanut skin peeling machine is a special equipment for removing the soaked peanut’s red outer skin. Wet peeling is a common method for peeling peanuts. The surface of the peanut after peeling is smooth and without damage. It is widely used in the early peeling treatment of peanut food.
This commercial wet type peanut skin peeling machine can peel not only peanuts but also almonds, broad beans, mung beans, soybeans, and more. It features a peeling rate of 92%–95%, a whole kernel rate of about 90%, and a breakage rate below 2%, making it a versatile and highly efficient machine.
This machine has a capacity of 250 kg/h. The parts in contact with the materials are made of 304 stainless steel, ensuring high output, no contamination, corrosion resistance, and easy cleaning.
Here is a video of the machine in action, giving you a general idea of how it works.
What is wet type peanut skin peeling？
In fact, there are two methods to remove peanut skins: wet peeling and dry peeling.
Wet peeling involves soaking peanuts in hot water for 3–5 minutes, then pouring them into a hopper. The peanuts enter a rotating rubber drum, where friction with rubber rings removes the red skins. The peeled peanuts are then discharged through different outlets.

Advantages of a peanut skin peeling machine
High Peeling Rate with Low Breakage
The machine adopts an efficient rubber friction peeling system, achieving a peeling rate of 92–95% and a whole kernel rate of up to 90%.
The breakage rate is below 2%, ensuring that peanuts remain intact and reducing raw material loss.
High Productivity and Labor Saving
With an output capacity of 250 kg per hour, this model is 8–10 times more efficient than manual peeling.
It is ideal for small and medium-scale food processing plants, peanut butter production lines, and almond or soybean beverage preparation.
Compact and User-Friendly Design
The machine measures 118 × 85 × 110 cm, featuring a compact structure that saves space and fits easily into production lines.
It is made of high-quality stainless steel with durable rubber rings, ensuring food safety, corrosion resistance, and easy cleaning.
Automatic Separation System
Equipped with an automatic kernel and skin separation device, the machine discharges skins and kernels separately after peeling.
This eliminates manual sorting, improves efficiency, and keeps the working area clean.
Superior Product Quality
The peeled peanuts or almonds have a clean, bright surface without browning, while protein activity remains unchanged.
The final products are ideal for further processing into almond milk, canned almonds, peanut paste, and other food or beverage items.
Energy Efficient and Stable Performance
Driven by a 0.75 kW high-efficiency motor, the machine runs smoothly with low noise and low power consumption.
Its energy usage is only 70–80% of similar models, offering both high productivity and cost savings.

Structure of the wet peanut skin peeler
Feeding hopper
Used to put soaked peanuts or almonds into the machine evenly. The hopper design prevents material blockage and ensures smooth feeding.
Peeling unit
The core part of the machine, made up of rubber rollers, friction rings, and a driving shaft.
Through soft rubber friction, the red skin is gently removed without breaking the kernels.
Separation system
Includes a wind or centrifugal separator that automatically separates the skins from the kernels.
The peeled peanuts come out from one outlet, and the skins are discharged from another.
Transmission system
Powered by a 0.75 kW motor with belts, chains, and bearings.
It provides stable power, low noise, and long continuous working hours.
Machine frame and body
Made of high-quality stainless steel, strong, durable, and corrosion-resistant.
The smooth surface is easy to clean and meets food hygiene standards.
Control system
Equipped with a simple control panel for easy start, stop, and speed adjustment.
Safe and convenient for operators.
How does the wet type peanut skin peeling machine works？
The wet peanut peeling machine works by using the friction of rubber rollers to remove the red skin from the peanuts.
First, the peanuts are soaked in warm water for 3–5 minutes to soften the skins. Then, they are evenly poured into the feeding hopper. When the machine starts, the rotating rubber rollers gently rub the peanuts, quickly removing the red skins without damaging the kernels.
After peeling, the separation system automatically divides the skins and kernels through different outlets. The peeling rate reaches 92–95%, and the whole kernel rate is about 90%.
The peeled peanuts are white, smooth, and non-browning, ready for further processing into peanut butter, peanut milk, and other food products. It is an efficient, energy-saving, and hygienic peeling solution.
Common machine problems and solutions
Question 1: The discharge outlet discharged more peanuts without peeling
Answer: may be due to the uneven size of the peanuts, resulting in some of them not peeling. Peanuts can be graded before they are treated, which will greatly increase the rate of peeling.
Question 2: After peeling, the crushing rate of peanuts was higher
- Answer 1: The space between cots is too small, causing some peanuts to crush as they pass through the rollers. The clearance of cots can be adjusted appropriately.
- Answer 2: Peanuts soak for too long. It is necessary to strictly follow the treatment procedure and treat the material according to the appropriate soaking time.
Detailed applications of the wet type peanut skin peeler
Peanut butter and peanut paste production
In peanut butter or peanut paste production, the raw peanuts must be peeled to ensure a smooth texture and uniform color. The wet peeling machine efficiently removes red skins while keeping kernels intact and preserving protein activity. This provides high-quality raw materials for grinding, improving product quality and added value.
Almond and peanut beverage processing
For almond milk, peanut milk, and other plant-based beverages, raw materials need to be clean and free of skins. The wet peeling machine quickly removes skins, ensuring smooth texture and natural color in the beverage. It also reduces the need for further filtration or purification, increasing production efficiency.
Snack and confectionery production
For baked nuts, candies, roasted peanuts, and other snacks, peeled peanuts offer better taste and allow for even coating with sugar or seasoning. The machine can process large volumes, providing clean, white, and whole kernels that improve product appearance and consistency.
Canned nut processing
Canned peanuts, almonds, or mixed nuts require raw materials that are clean and visually appealing. Peeled kernels can be directly roasted, seasoned, or canned without secondary sorting, reducing production steps and labor costs while enhancing market competitiveness.
Food raw material preprocessing
The wet peeling machine can be used for preprocessing various food raw materials in beverage factories, snack manufacturers, and bakery plants. Peeled raw materials are clean, uniform, and hygienic, ready for grinding, mixing, roasting, or seasoning, ensuring product quality and processing efficiency.
Peanut further processing
