1. DRYING
● For two days without sun exposure until dry and then the dried nuts are stored in storage.
● the loss of the sun brightness due to DRYING reaches 7% - 8%.
● This increases the cost of RAW cashews.
● Sunlight changes the color of the cashew nut and turns brown.
● Once the color has changed, the cashew is known to be dry, this is done to remove the oil content from the shell.
● The units are then not bagged and returned to the warehouse until the next process begins.
● This can be one or two days depending on stock.
2. ROASTING
■ Makes the cell brittle and facilitates grain removal.
Open pan for roasting.
■ 1 kg of walnuts is stored in an iron silo pan or clay pot or heated over low heat.
■ rotated quickly to avoid burning.
■ large amount of cellular liquid and irrigation effect with smoke splashes and lesions on the skin of the person involved.
■ Roasted nuts: they are removed and thrown on the ground.
■ then covered with soil, to absorb the liquid from the cells and cool them.
■ The child can also roast it for 2 or 3 days.
Drum roasting method
♢ The roasting of raw cashews takes place through the steam roasting process.
♢ This process runs for 20 minutes at 90 degrees Celsius.
♢ Wood is used here for the steam generation process to roast the cashew nut.
♢ In this process, 4 boxes of 80 kg each are placed in a container and a lot of steam is released.
♢ The 10 minutes of steam we released will come out of the container door.
♢ After 8-10 minutes we must stop the steam and the door must be open.
♢ These raw roasted cashews.
Oil bath process
♢ The nuts are stored on the baking tray.
♢ Go through a cashew cell oil bath maintained at 202 degrees Celsius. Even roasting and eliminates the exchange of beans.
♢ 50% liquid shell can be obtained.
Steaming
♢ Raw walnuts - steamed at 100-110 kg per square cm for 15 minutes.
♢ Spread out on the floor to cool.
♢ Peel the next day, the whole grain looks better.
♢ 75% of the CSNL is extracted.
3. COOLING
Once roasted, the raw nuts are taken to a separate room and sprinkled on the floor.
⊙ They are stored here for 2 or 3 days to cool down.
⊙ Once cooled, they are transferred to the next process.
4. CUT
☆ The whole cutting process is responsible for working women.
☆ Women work in a machine and can process 8 to 10 kg of cashew nuts per day.
☆ These banknotes are then fed into the manual cutting machine to separate the beans from the shells.
5. DISCOVERY
• It is a cashew shell, it opens and the cashew nut inside is removed immediately by hand.
• • Bombing is a technique that can be easily learned over and over again.
• No force is required to break the shells.
• The most important thing is the correct positioning of the nut and the ability to hit the one that is not in the correct position to allow it to break.
• • Therefore, quality control and inspection are essential to ensure that cells produce the highest quality beans.
• During the shelling process, the worker uses castor oil to keep their hands safe.
6. HOT CHAMBERS/BORMA DRYING

▪▪ The cashews that are cut are taken to a hot chamber for drying on the mat.
▪Borma which looks like a rectangular box each containing 60 aluminum trays (480 trays).
▪ 4 kg of cashew nuts are being loaded into a tray (total input tray 1920 kg) and the door is closed.
▪ Raw cashew nut sales cake is used as fuel.
the door locks and the heat is generated at 81 degrees centigrade and released into the borma box for 8 continuous hours.
▪After that, the cashew kernels are taken to a separate room to cool them for storage, this process continues for a whole day.
7. PEELING
○ So, most of the employees are working on the process. the average peel for an employee is 10 kg.
○ Here the worker removes the cashew shell with the help of a small knife.
○ These are transferred to the evaluation section the next day.
8. EVALUATION
□ This process in which cashews are classified and assigned to different grades.
□ Depending on the grades, the taxes are established.
□ Degree different from our total 120, integer 144 and 180, integer 240 integer 300 integer 350 and integer 440.
9. CLEANING
♤ In this process, the cashew nut is passed to a machine where the dust is removed.
♤ Once this is done, the clean dice go through the metal detector.
♤ This is done to ensure that there are no unwanted particles.
♤ This is the final process before packing.
10. WEIGHING
♧ This is done for the purpose of packaging. Here the nuts are placed in containers, sacks and bags as per the requirement.
♧ Once this is done, the containment containers move on to the next process.
11. PACKAGING
● Packaging is an important activity as it contains the final product.
■ Packaging should be made in a way that is convenient and attracts the customer to purchase the product.

1. Cashew nut shell liquid
■ Has some medicinal and industrial uses.
■ CNSL is one of the few natural resins with high heat resistance and is used for the braking system and for the production of the final paint.
■ Contains a compound known as cashew which is used to treat dermatological disorders.
■ Used as raw material for phenolic resin and friction powder for the automotive industry (brake linings and clutch discs).
■ In the drum brake lining compound, cashew resin is used as a filler and can also be used as a binder.
■ In the disc pad, the role of cashew shavings is limited to the use of friction powder as a filler. The advantage of cashew resin over synthetic phenolic resins is that they are cheaper and produce a softer material, which provides a quieter braking action.
■ CNSL is also used in the molding of acid resistant paints, casting resins, paints, enamels and black lacquers for the decoration of vases and as an insecticide and fungicide.
■ In tropical medicine, CNSL has been used to treat leprosy, elephantiasis, PSORIASIS, ringworm, warts and corns.
2. Cashew shell
■ The sale of cashew nuts can be combined to provide heat for the decorating operation.
■ Can be used in the manufacture of particle board.
■ Together with the head, it can be used both in the production of dyes and to give durability to hammocks and fishing lines..
