The cashew nut processing plant is also called cashew nut shelling line and cashew nut peeling line. The production line applies mainly to shell and peel cashew nuts and finally get peeled cashew nuts. The production line composes semi-automatic cashew nut processing machines. Therefore, the nut processing line is called a small cashew nut production line. The small cashew nut processing plant mainly includes a hoist – grading machine – steam cooker- cashew shelling machine – shell kernel screening machine – cashew nut drying machine-cashew nut peeling machine-cashew nut sorting machine.
Small cashew nut processing plant introduction
Cashew nut is rich in nutritional value and is one of the world’s four major dried fruit. It can be processed into many flavors of cashew. The cashew processing line is a series of equipment specially designed for processing cashew nuts. It will get the peeled cashew nuts after processing. All cashew nut processing machines are designed to replace manual labor according to the requirements of the food processing industry. This production line is easy to operate and can avoid environmental pollution. It is fully in line with food processing standards with low energy consumption and high efficiency.
Cashew nut manufacturing process
This is the first step in the cashew nut processing plant. Put the raw material into the hopper, and the hoist deliveries the material to the cashew nut grading machine for nut grading. It will reduce manpower input and more efficiently. The motor adopts a speed regulation motor. You can adjust the speed of the hoist according to actual needs.
Cashew nut grading machine
It is a very important step in the cashew nut peeling processing line. Put the raw cashew nut into the grading inlet. Adjust the hopper quantitative gate to control the feed amount of raw materials. Raw material falls into the sieve. Grading the cashew nut in the rotation of different aperture screens. Due to the size of the cashew is different, so it will improve the cashew integrity when shelling after grading. Generally, it can divide cashews into 3 – 5 levels( or customize according to customer’s requirements). The level is divided into four according to the cashew width: under 20 mm, 20–23 mm, 23–26 mm, more than 26 mm. This machine composes transmission structure, hierarchical structure, frame, and other parts.
The cashew nut cooking machine applies for steaming cashew nuts. After cooking, the shell and kernel of the cashew nut will have gaps, it can achieve a better shelling effect. The heating method of the cashew cooking machine includes electric heating and steam heating.
Cashew cooking machine usage method
Electric heating machine
First, fill the water tank to preheat. After the water in the water tank boils to produce steam, disconnect the power supply. Then slowly open the door lock to reduce the high-temperature steam in the rice cooker. Then open the door, close the door and lock the food to steam, and continue heating.
Steam heating machine
Connect the steam source to the “steam input port”. Slowly open the steam valve and observe if the pressure in the pressure gauge meets the requirements. Ensure that the input steam pressure does not exceed 0.02MPA. Start to preheat, preparing steamed food after the steam is discharged. Close the steam valve and slowly opens the door lock before putting food into it. After releasing the high-temperature steam in the rice cooker, open the door and put in the food to steam.
Cashew shelling machine
This machine is one of the key steps in the small cashew nut processing plant. To get the ideal shelling effect, it needs to grade the cashews first. When cracking the shell, needs the same size cashew nuts. It can adjust the gap of the feed hopper in a certain range. You can adjust the height of the blade according to the cracking situation.
Shell kernel screening machine
After cracking the cashew nut shells, it needs a shell kernel screening machine to separate the cashew nut shells and kernels. This can reduce manual labor and increase production efficiency. The machine has the characteristics of low energy consumption, high output, simple structure, and convenient maintenance.
It is easier to peel cashew nut after drying, so in order to get a higher peeling rate, needs a cashew nut dryer to dry cashew nuts.
When the wind is blown out by the circulating fan, it passes through the air duct and encounters the radiating pipe. Then the hot gas heats the cold air., and the hot gas heats the raw material. After heating, material moisture will evaporate due to heat. Then the gas containing a certain amount of water is brought back by the circulation fan and then repeat the work. But some of the water will be automatically drained through the drain. This recycling work to achieve the purpose and requirements of drying. The temperature of the dried cashew nuts is about 80 degrees Celsius, and it takes about 3 hours at a time.
The peeling machine generally equips with an air compressor. Use the thermo-pneumatic principle to remove and separate the cashew skin. No damage to cashew nuts. It has the characteristics of time-saving, labor-saving, and high efficiency. Dry peeling has no pollution to the environment. The peeling rate is 95-98%. It does not rust and meets the requirements of the food industry.
Cashew kernel sorting machine
The cashew nut grading machine applies for grading various sizes of cashew nuts. The machine can classify cashew nuts into multiple grades.
You can adjust the gap between the rollers according to the size of the cashew nut. The machine mainly uses different sizes of meshes at different levels to classify cashew nuts of different sizes. The largest cashew kernels are separated from the first level, while the smallest cashew kernels are sieved from the last level. Adjust the clearance by loosening the bolts on both ends of the roller shaft. Nuts evenly enter the roller. Adjusting the vibration amplitude of the material placing the machine in the controller of the stepped electric control box. Vibration amplitude becomes larger when clockwise, and the vibration amplitude becomes smaller when counterclockwise.
The cashew nut processing line already has a very mature technology. The cashew peeling line is the first step for the deep processing of cashew nuts. We can customize the machine according to the specific requirements of customers. The production line has high production efficiency. Peeled cashews can be further processed into various foods. Cashew food has good prospects in the food industry with fast recycling and high returns, which are worth investing in.
