The cashew nuts are highly sought after for their rich nutritional value and widespread market demand. However, traditional cashew nut processing methods are time-consuming, labor-intensive, inefficient, and difficult to maintain consistent product quality. With the continuous advancement of food mechanization and intelligent processing, cashew nut processing lines have become an ideal choice for many processing plants and investors. They not only ensure high-quality cashew nuts and yield but also reduce labor costs and improve overall production efficiency. Contact us for inquiries! WhatsApp/Phone: +86 13838385752.
Production Line of Cashew Description
This cashew nut processing line is centered around automation, standardization, and intelligence. Combining advanced processes and high-performance machinery, it enables comprehensive cashew nut processing, from raw nut grading to finished product packaging. The modular design enables flexible configuration tailored to business needs. This makes it suitable for both large and medium-sized processing plants.
The entire line encompasses steps such as raw nut grading, steaming, cooling, shelling, screening, drying, peeling, color sorting, and vacuum packaging. This minimizes manual intervention and enhances product quality and safety.

Production Process of Cashew Nut Processing Line
The entire cashew nut production line has a clear process flow, primarily divided into the following steps:
- Raw Material Grading: Cashew nuts of different sizes are graded using a grader to ensure that subsequent processes are compatible with shelling equipment of varying nut diameters.
- Steaming and Natural Cooling: Graded cashew nuts are steamed to soften the shells. They are then naturally cooled for easier shelling.
- Automatic Shelling: The raw nuts are fed into an automatic shelling machine, using different models of shellers for different nut sizes. Adjustable gaps ensure efficient shelling.
- Shell-Kernel Separation: After shelling, the kernels are separated from the shells by screening and wind separation equipment. The shells can be further extracted for oil. While the kernels are fed to the next process.
- Secondary Shelling and Manual Sorting: Nuts that have not been fully shelled or whose shells are stuck to the kernels undergo secondary processing using centrifuges and screening machines, supplemented by manual sorting.
- Kernel Drying and Humidification: After drying, the kernels are treated in a humidifier to facilitate peeling.
- Peeling and Color Sorting: Kernels that remain partially shelled are sorted again by color sorting machines or by hand to obtain clean, white kernels.
- Secondary Roasting and Seasoning: Cashew kernels can be further roasted or seasoned to create a variety of flavors.
- Packaging: Finally, they are packaged in a vacuum packaging machine to ensure product freshness and safety.
