Automatic Cashew Nut Sheller Machine

The cashew nut sheller machine is one of the key machines in a cashew nut processing plant. It is mainly used to shell cashew nuts after proper pre-treatment. With a stable mechanical shelling process, the machine achieves a high shelling rate and good kernel integrity, making it suitable for medium- to large-scale continuous cashew processing operations.

In practical production, raw cashew nuts are normally graded and steamed before shelling. This process softens the shell, improves shelling efficiency, and prepares the kernels for the subsequent peeling process.

Standard Pre-Treatment Before Cashew Shelling

To achieve stable shelling performance, the cashew nut shelling machine is usually operated together with the following upstream processes:

• Raw cashew nut grading to ensure uniform size
• Steaming treatment to soften the shell and reduce kernel breakage
• Cooling and temporary storage to ensure consistent material condition before shelling

Proper pre-treatment significantly improves shelling efficiency and reduces kernel damage.

Working Principle of the Cashew Nut Sheller Machine

The cashew nut sheller machine uses an adjustable shelling structure to crack graded cashew nuts accurately.
By adjusting the shelling gap, the machine can process different cashew sizes effectively.

Under normal operating conditions:

• Shelling rate: up to 95%
• Whole kernel rate: approximately 85%

These performance levels are well suited for industrial cashew processing.

Multi-Head Design for Different Capacity Requirements

We design and manufacture automatic cashew nut sheller machines with 4 to 12 shelling heads, suitable for different production capacities.

• 4-head model: shells 4 cashew nuts simultaneously
• 6 / 8 / 10 / 12-head models: increased output accordingly
• Each model corresponds to a different hourly capacity

Customers can select the appropriate model based on their target output. We also provide model recommendations according to actual production requirements.
