Cashew Nut Sieving Machine

Cashew nut sieving machine independently developed by our company is a machine specially designed for cashew grading. It is easy to operate.

Cashew Nut Sieving Machine

In cashew processing plants, grading cashew kernels by size is an essential step before packaging and export. Different kernel sizes such as W180, W240, W320, and W450 require precise classification to meet international market standards. A reliable cashew nut sieving machine helps processors improve product consistency, reduce manual labor, and increase grading efficiency.

Our automatic cashew kernel grading machine is specially designed for sorting whole and broken cashew kernels according to width and size. It is suitable for small, medium, and large-scale cashew processing factories.

What Is a Cashew Kernel Grading Machine?

A cashew nut sieving machine is used to separate cashew kernels into different size grades through adjustable gaps or rotating drum structures. Since cashew kernels naturally vary in size, grading is necessary to ensure uniformity for packaging and export.

The machine can classify kernels into several grades, including:

  • Below 8 mm
  • 8–10 mm
  • 10–12 mm
  • Above 12 mm

The grading levels can also be customized according to customer requirements.

Types of Cashew Kernel Grading Machines

We provide two common types of cashew kernel sorting machines:

Multi-Roller Cashew Nut Grading Machine

The multi-roller type grading machine uses adjustable roller gaps to separate cashew kernels by size. The machine is equipped with upper, middle, and lower grading rollers. By adjusting the distance between rollers, different kernel sizes can be accurately classified.

Features of The Cashew Kernel Size Grading Machine

  • Adjustable grading gap
  • Accurate size sorting
  • Stable operation
  • Easy maintenance
  • Suitable for different cashew kernel grades

This type is ideal for factories requiring flexible grading standards and higher sorting precision.

Drum Type Cashew Kernel Grading Machine

The drum type cashew nut sieving machine uses segmented rotating drums with fixed gaps for continuous grading. It is commonly used for separating broken kernels and sorting kernels into different size categories.

The machine first removes broken kernels and then grades the kernels according to size.

Drum Type Cashew Kernel Sieving Machine Features

  • Compact structure
  • Continuous grading process
  • Large processing capacity
  • Stable conveying performance
  • Simple operation

How Does the Cashew Kernel Sorting Machine Work?

The machine works by feeding cashew kernels into the grading section through the hopper. The kernels move between rollers or rotating drums, where different sizes pass through different gaps.

Large kernels continue forward to the front outlet, while smaller kernels fall through the adjustable gaps into separate discharge hoppers. This process ensures accurate classification without mixing grades.

The machine can continuously process cashew kernels with stable and efficient performance.

Advantages of Using a Cashew Kernel Grader

  • Improve Product Uniformity: Uniform kernel size is important for export standards and retail packaging.
  • Reduce Manual Labor: Compared with manual grading, the machine greatly reduces labor costs and improves efficiency.
  • Increase Processing Efficiency: The automatic grading process can handle hundreds of kilograms per hour.
  • Reduce Kernel Damage: The machine structure is designed to handle kernels gently and reduce breakage.
  • Customizable Grading Standards: Customers can customize grading sizes according to market demand.

Complete Cashew Processing Line Solution

Many customers not only need a single cashew nut sieving machine, but also want to build a complete cashew processing line.

In a standard cashew processing plant, raw cashew nuts are usually processed through several steps, including a raw cashew grading machine for size classification, steam cooking machine for softening the shells, cashew shelling machine for cracking the nuts, shell kernel separating machine for removing shell pieces, drying machine for moisture control, cashew peeling machine for removing the skin, and finally the cashew kernel grading machine for sorting kernels into different grades such as W240 and W320.

After grading, the kernels can be packed by a vacuum packing machine for export and storage. We can provide both single machines and complete cashew processing solutions according to your required capacity.

Applications of Cashew Nut Sieving Machines

This machine is widely used in:

  • Cashew processing plants
  • Cashew export factories
  • Nut processing industries
  • Food processing factories

It is suitable for grading:

  • Whole cashew kernels
  • Broken cashew kernels
  • White cashew kernels
  • Roasted cashew kernels

Why Cashew Kernel Grading Is Important

International buyers usually purchase cashew kernels according to standard grades such as W180, W240, W320, and W450. Accurate grading directly affects product price and export quality.

Using an automatic cashew kernel grading machine helps factories meet international grading standards and improve market competitiveness.
