The Raw Cashew Cleaning and Calibration Machine is designed to clean and grade raw cashew nuts with high accuracy. Available in configurations from simple to fully automatic, it suits processing lines that shell cashews by hand or by machine. The machine classifies raw cashew nuts by size within a range of 18 to 30 millimeters.
The machine is controlled by an advanced electronic system that automates the entire process, from feeding and cleaning to stone removal and size grading. The finished raw cashew nuts show high uniformity and precise classification, making them suitable for both roasting and steaming technologies.

All key parts, including the motor, chain, and electrical components, are imported from the EU or meet CE standards, ensuring reliable and long-lasting performance. The machine can operate independently or be connected with other machines to form a high-performance automatic production line. It is easy to operate and maintain.
