The cashew nut production line is mainly designed to process unshelled cashews into peeled cashew kernels and complete vacuum packaging. The complete line includes grading, cooking, drying, shelling, screening, secondary drying, peeling, kernel grading, roasting, and vacuum packing. With a peeling rate of over 98%, it is highly suitable for cashew processing plants of all sizes.
This cashew klernel production line has a capacity of 100–800 kg/h. According to your production requirements, you can choose between a fully automatic cashew processing line or a semi-automatic cashew processing line. Feel free to contact us for more details and professional consultation.

Process flow of Cashew Nut Production Line
This cashew production line is a complete technological process, which is the preliminary comprehensive processing of cashew after picking. The whole production line adopts semi-automatic operation, compared with the traditional manual processing, the efficiency will be higher, at the same time cashew damage rate will be greatly reduced.
The processing technology of the cashew nut production line requires the following machines:
Cashew Nut Grading Machine
First of all, the initial grading of cashews is to facilitate the subsequent opening of the shell. Because the size of cashews varies, the shelling machine uses the distance between the blades to open the shell. So before opening the shell need to ensure that the size of the cashews is uniform.
The size of cashew nuts is generally divided into 16, 18, 20, 22, and 24mm. The grading machine realises the grading processing of cashew nuts through screens with different pore diameters. Customers can choose the number of grades that should be divided according to actual requirements.
Cashew Cooking Machine
The graded cashews are put into the cooking box . According to the size of cashews, the cooking time is different. The cooking time of cashews with smaller volumes is longer, and the cooking time of cashews with smaller volumes is vice versa.
The main purpose of cooking is to use the principle of heat expansion and cold contraction. So as to separate the shell from the cashew peel and reduce the damage to the cashew nut when the shell opens.
Note: After cooking the cashews, the cashews should be placed in a ventilated place for 2-3 days.
Cashew Nut Sheller And Kernel Separator
The shelling machine is divided into the semi-automatic type and automatic type . With a high rate of shellers, the characteristics of small damage to nuts, which is the automatic type of cashew sheller, are the first choice of most customers. The operation principle of these shellers is also very simple.
After the cashews are sent into the feed mouth, the roller will initially clean the cashews and remove the impurities, such as stones mixed into them. Then the cashew nuts will be evenly placed in the shell opening mould and transported to the shell opening device. After the action of the pushing device, the cashew nuts will be cut by the blade, and the cashew nuts will be opened.
After opening, the cashew shell has not been completely separated from the nuts, so it is necessary to use the shell separator to separate the shell and nuts completely.
Cashew Drying Machine
The cashew drying machine is used to remove excess moisture from cashews after cooking or shelling, ensuring stable quality and easier peeling.
It features uniform hot-air circulation for even drying, stable operation, and adjustable temperature and time.
This machine helps improve kernel integrity, reduce breakage, and is suitable for small, medium, and large cashew processing lines.
Cashew Kernel Peeling Machine
The cashew kernel peeling machine efficiently removes the thin skin from cashew kernels while keeping them intact. It has a high peeling rate, reduces breakage, and is suitable for small, medium, and large cashew processing lines
Cashew Kernel Grading Machine
The cashew kernel grading machine is used to sort peeled cashew kernels by size and quality. It ensures uniform grading, improves processing efficiency, and helps maintain consistent product quality. Suitable for small, medium, and large cashew processing lines.
Cashew Kernel Vacuum Packing Machine
The cashew kernel vacuum packing machine is used to vacuum-seal peeled cashew kernels, effectively extending shelf life and protecting them from moisture and oxidation. It keeps the kernels fresh and intact, operates easily, and offers fast packaging speed, suitable for small, medium, and large cashew processing plants.
