Consistent size grading is essential for getting the best price for cashew kernels. The TPG-KG400 Cashew Kernel Grading Machine is an automatic grader that sorts kernels into 3 to 5 different sizes with precise separation, high output, and zero damage. It processes 400 kg per hour, making it a dependable choice for factories specializing in cashew processing.
Overview
The TPG-KG400 automates the entire grading process, from feed intake and sundries removal to stuff promotion (lifting) and screening. Kernels are loaded, cleaned of foreign matter, lifted to the grading section, and separated by size, so operators can handle the whole process with minimal effort.

How It Works
The machine uses three layers of rollers:
- Upper layer: separates out the big kernels
- Middle layer: separates out the medium kernels
- Lower layer: separates out the small kernels
The size of each grade is set by adjusting the gap between the rollers on each layer, so the machine can be tuned easily to different kernel sizes and grading requirements.
Key Advantages
Exact grading. Adjustable roller gaps allow precise size separation into 3 to 5 grades.
Zero damage. The roller grading method handles kernels gently, protecting whole kernels and preserving their value.
