Cashew shelling machine is one of the cashew nut processing machines that contributes to improving the position of Vietnam's cashew industry. In addition to the above name, they also have another name, cashew nut splitting machine. If you want you can learn the type of cashew nut separator in English, they are called cutting machines (or shelling machines). In addition to machine separation, cashews are also separated by the following methods:

Manual: use pliers to separate cashews.
Semi-manual: use a manual cashew nut cutter or a mini cashew nut splitter or a manual cashew nut splitter.
How does the cashew nut separator work?
Raw cashews will be poured into the top feeding hopper of the cashew separator. Then the seeds will be transferred to 4 material dividers. Corresponding to 4 split pipes are 4 split machines. Raw cashews are placed vertically for easy splitting. The cashew kernel will then be sorted out of the cashew shell. Cashew shells are separated to serve the hull coating industry. For broken or unsplit seeds, this process will be repeated.

In general, the productivity of cashew nut shelling ranges from 40 kg/hour to 2 tons/hour. It is very important to sort raw cashews before they are put into shelling. Therefore, our advice is that you should buy a cashew nut sorter and splitter from the same manufacturer. To get the "uniformity" in the operation of the two machines. Avoid the situation of "the drum blows forward, the trumpet blows backwards". With factories building a closed processing model, they often have a skilled technical maintenance team.

The method of separating hard shells with cashew nut pliers and manual cashew nut cutting table.

The manual cashew nut cutting table requires the coordination of the worker's hands and feet. Raw cashews are first sorted and steamed. The purpose is to neutralize the acid in the cashew shell. Another reason is because fresh raw cashew nuts often have very hard shells, which are difficult to pry, so when pry, the percentage of broken seeds is high.

Shellers need to wear gloves carefully. The reason is to avoid the remaining plastic layer of cashew nuts eating into the skin of the hands. Another requirement is that the gloves must be close to the hand to facilitate manipulation. In addition, the ploughman often wraps his thumb because if he is not careful, his hand will be cut.
Your whole body needs to be covered to prevent the resin from getting in. In case of a lot of stickiness, it will be very painful, difficult to heal, even leaving scars. In case cashew resin gets into eyes, it should be washed immediately with eyes because it will be very painful.
After fully wearing "armor", the next step is to put the cashews in the split knife. Be sure to use your left thumb to hold the top of the bead. Use your middle and index fingers under the split knife to lift. Note that the back of the grain is facing the splitter.
The next step is to gently step on the bottom pedal to let the blade cut the hard shell.
Then use the right hand to pry the kernel out.
Repeat the above 5 steps with other beads.
The productivity of the manual cashew nut cutting table depends on the worker's ability and the number of workers per shift. The productivity of Vietnamese plowmen is usually 3 to 5 kg/day. Small kernels are about 3 kg / day because the difficulty level is higher. According to cashew organizations, the productivity of African workers ranges from 35 to 40 / worker / shift. Vietnam-made manual cashew nut cutting table is rated as the most productive.

Cashew pliers are often used to check the cashew recovery rate. Andy already has an article on how to use pliers to split cashews, so please don't mention it here.

Cashew splitter provided by Danielmachine: Machine dimensions are 8.2 m(length) * 5.3 m(width) * 3.5 m(height). Machine weight is about 2.5 tons. Cashew splitter uses 380V (3 phase) power. Energy consumption 10 kW/h. The percentage of seeds announced by Danielmachine will range from 2-4%. While the percentage of particles that have to be trusted is below 7%. The capacity and ratio of granules tank varies according to the type of granules. Specifically:

If split grade A, the capacity is from 140-160 kg / set of 4 split heads / hour. The percentage of broken seeds is from 2-4%.
If split type B, the capacity is from 110-130 kg / set of 4 split heads / hour. The percentage of broken seeds is 3-5%.
If split grade C, the capacity is from 90 to 110 kg/unit/hour. The percentage of broken seeds is from 4-6%.
