A cashew raw grader is a specialized machine used in the cashew processing industry. Its primary function is to sort raw cashews based on their size and quality. Graders typically use different mechanisms such as screens with different-sized holes or vibrating trays to separate the different grades.

The grading process is crucial as it helps ensure consistency in the final product. Larger and higher-quality cashew nuts are often segregated for premium markets or specific uses, while smaller or lower-grade nuts may be used in a variety of products or processed differently.

Overall, a cashew raw grader plays a significant role in optimizing the efficiency and quality of cashew processing operations by grading raw cashews according to predetermined standards.
