When it comes to improving productivity and kernel quality in cashew processing, a high-performance cashew nut grading machine is essential. Designed for precision and durability, our Cashew Grading Machine (Model: HQT-100 / HQT-200) offers consistent sizing, reduced labour costs, and improved downstream processing efficiency—making it an ideal choice for processors across South Africa and wider African markets.
Machine Introduction
The cashew nut grading machine is designed to separate cashew kernels into uniform sizes for improved product quality and export standards. It is widely used in modern cashew processing plants after the peeling stage to achieve consistent grading results such as W180, W240, W320, and other commercial grades.
This machine delivers stable operation, high grading accuracy, and efficient continuous processing for small, medium, and large-scale cashew factories.
Machine Features
- High grading accuracy for uniform kernel sizing
- Multi-layer grading system supporting 3–6 grades
- Low kernel breakage rate during sorting
- Food-grade stainless steel contact parts
- Stable vibration structure for continuous operation
- Adjustable grading screens for different kernel sizes
- Compact machine design with easy maintenance
- Suitable for manual and automatic processing lines
The machine is engineered to improve grading consistency while reducing labour intensity and processing losses.
Technical Specifications
| Model | Capacity (kg/h) | Power (kW) | Grading Levels |
|---|---|---|---|
| G300 | 300–400 | 1.5 | 3–4 grades |
| G500 | 400–600 | 2.2 | 4–5 grades |
| G800 | 600–800 | 3.0 | 5–6 grades |
Machine size and grading configurations can be customised according to factory requirements.
Application
The cashew grading machine is suitable for:
- Cashew kernel processing factories
- Export-oriented cashew plants
- Medium and large-scale processing lines
- Cashew packaging and sorting facilities
It can operate independently or integrate into a complete cashew processing production line.
Processing Advantages
Using a professional cashew grading machine helps processors achieve:
- Improved export-grade consistency
- Higher product value and market acceptance
- Faster sorting efficiency compared to manual grading
- Reduced labour costs
- Better downstream colour sorting performance
- Stable production output for commercial processing
Uniform kernel grading is essential for meeting international market requirements and improving final packaging quality.
Cashew Processing
The grading machine is commonly installed after peeling and before colour sorting in the processing workflow:
Raw Cashew Cleaning → Steaming → Shelling → Drying → Peeling → Grading → Colour Sorting → Packing
Proper grading improves the efficiency of later processing stages and helps maintain consistent finished product standards.
Recommended Processing Equipment
- Cashew Shelling Machine
- Cashew Peeling Machine
- Colour Sorting Machine
- Cashew Dryer
- Our cashew grading machine can integrate with colour sorting systems and other cashew processing equipment for improved production efficiency.
Machine Construction
The machine is manufactured using durable industrial materials for long-term operation.
