Full Cashew Nut Processing Line Vietnam – From Raw Nuts to Vacuum-Packed Kernels

Vietnam is one of the world’s leading countries in cashew nut processing, known for its advanced technology, high productivity, and consistent quality. In this article, we introduce a complete overview of the full cashew nut processing line in Vietnam, covering every stage from raw cashew nuts to final vacuum-packed products ready for export.

🔹 1. Raw Cashew Nut Receiving and Size Grading

The process begins with receiving raw cashew nuts, usually imported or collected locally. These nuts are fed into an automatic size grading machine to classify them into different sizes (typically A+, A, B, C, D). Accurate grading ensures better shelling efficiency in later stages.

🔹 2. Steam Cooking (Steaming)

Graded cashew nuts are then transferred into steam cookers or cashew nut boilers. Steam softens the shell, making it easier to crack without damaging the kernel inside. Proper steaming also reduces kernel breakage during shelling.

🔹 3. Shell Cutting (Shelling)

Once steamed, cashews go through the automatic shelling machine, where sharp blades open the shell and extract the nut. Modern Vietnamese factories use multi-blade shelling machines, which significantly improve capacity and reduce labor costs.

👉 This is one of the most critical stages in the entire cashew processing line. The efficiency and precision of the shelling step directly affect the overall productivity of the factory. If the machine is not well calibrated or the shelling process is not optimized, it can lead to a high breakage rate or uncut nuts, which reduces kernel value and increases manual labor requirements.

At TTQ, we offer automatic shelling machines with adjustable blades and customizable cutting mechanisms, helping factories maintain a shelling rate of over 95% while keeping the kernel breakage rate under 6%. Choosing the right shelling technology ensures stable output and high-quality kernels that meet export standards.

🔹 4. Drying Process

After shelling, the extracted cashew kernels are dried to reduce moisture content and prepare them for peeling. Hot air or calorifier dryers are commonly used, ensuring the product reaches optimal humidity for easy skin removal.

🔹 5. Peeling (Removing the Testa)

Once dried, the kernels go through a steam humidifier before being processed by automatic peeling machines. These machines remove the thin brown skin (testa) from the kernel while maintaining its whole shape and appearance.

🔹 6. Kernel Grading and Quality Sorting

Kernels are then classified by size, color, and quality. This stage involves vibrating sieves, color sorting machines, and manual inspection. It ensures only high-quality cashews proceed to the final packaging stage.

🔹 7. Vacuum Packing

In the final step, the clean kernels are weighed, filled into bags, and packed using vacuum packaging machines. This method ensures long shelf life and protects the product from oxidation, moisture, and pests during shipping.
