Cashew Nut Shell Liquid (CNSL) Extraction Plant
Cashew Nut Shell Liquid (CNSL) is a versatile by-product of the Cashew Processing Plant. The nut has a shell which is a soft honeycomb structure containing a dark reddish brown viscous liquid. It is called cashew nut shell liquid. It is often considered as the better and cheaper material for unsaturated phenols.
We are a prominent manufacturer of untreated CNSL Extraction Plant. CNSL possesses special characteristics for transformation into speciality chemicals and high-value polymers. The chemical transformation provides 100% chemically pure products.
Major Cashew Processing countries are – Vietnam, India, Tanzania, Ghana, Ivory Coast, Benin, Nigeria and Guinea-Bissau.

Machinery & Equipment required to set up a Cashew Nut Shell Liquid (CNSL) Extraction Plant
Here we have listed some of the basic machinery required to set up a Cashew Nut Shell Liquid (CNSL) Extraction Plant
- Oil Expeller / Oil Press
- Reaction Vessel
- Steam Boiler
- Bucket Elevator
- Screw Conveyor
- Oil storage tanks
- Volumetric filling machine
- Control Panel
Cashew Nut Shell Liquid Extraction Plant Process
In the Cashew Nut Shell Liquid (CNSL) Extraction Plant, the Cashew Nut Shell undergoes the following steps: Oil Extraction, Neutralization and Oil Storage.
Oil Expeller / Oil Press
Cashew nut shells contain 20 – 25 % oil content. After pressing, a residual oil of less than 10 – 12 % is left in the oilcake.
The working principle of the Cashew Nut Shell Press is to forcefully push the cashew nut shell through the chamber by the action of the rotating screws. As the shell moves towards the discharge end, the screw pitch reduces thereby causing compression. Due to this increased pressure, the oil is squeezed out from the cashew shells and expelled out through the gaps in the chamber.
Reaction Vessel
The cashew nut shell liquid as extracted has a strong vesicant dramatic action. Before this liquid is utilised for preparation of resins, it requires treatment to get rid of metallic impurities as well as traces of sulphur compounds. Hence, Reaction Vessel is required to treat the extracted CNSL.
The Reaction Vessel is a Cylindrical Reactor with conical bottom consisting of Steam Heating Coils, Open Steam arrangement, Agitator & Drive.
Steam Boiler
The Steam Boiler is a closed vessel that generates Steam. This steam is let out through a pipeline that is directly connected to the Reaction vessel.
We provide both Vertical & Horizontal Multi Tubular Shell Type Smoke Tube Boilers. Our Boilers can be used on a variety of fuels such as coal, shells, husks, wood or other agricultural waste, Furnace Oil, Diesel, Gas, etc.
Bucket Elevator
Bucket elevator is the most suitable equipment to transport cashew nut shells vertically, without damaging them. A bucket elevator consists of a chain of buckets attached to a belt or chain, with pulleys located above and below the unit.
GOYUM designs and manufactures a wide variety of bucket elevators based on bulk raw material characteristics and process requirements.
Screw Conveyor
Screw conveyors are used for conveying raw material in oil mill equipment with the use of rotating helical screw blades also known as augers.
We supply a standard and custom configuration Screw conveyor to meet the needs of your process. MS or SS construction, U-trough type casing with top cover, screw flight welded to the pipe and with the necessary shaft, hanger bearings etc.
Control Panel
Dust and Vermin Proof Electrical Control Panel is powder coated and wired to ensure longer functional life. This Panel is fabricated using a quality grade MS Sheet provided with a MIMIC diagram. This Panel ensures optimum performance in any working condition and is widely used in industrial applications. It includes MCB’s / MCCB, Starters, Internal Wiring, Contactors, Meters, Push Buttons, Overload Relays, Indicators and Hour Counting Meter for Expellers
Cashew Nut Shell Processing Background
Cashew nut shells in Africa today are largely treated as a waste product of cashew processing and are disposed of at an economic and environmental cost. However, the shell can be used to generate energy, providing three layers of influence that increase the profitability and competitiveness of the cashew sector in an inclusive and sustainable manner.
Cashew shell (CNS) and its liquid extracts (CNSL) rich in particularly valuable and functional renewable products have been identified as agro-wastes. The unique structural features of CNSL components provide the possibility for various modifications to suit different applications. The CNSL for use in the production of biochemical, materials and energy as green sources. Methods and applications for the extraction of CNS, CNSL and isolates are discussed. In addition, a literature survey of the current situation and efforts made on the use of these agricultural and food wastes for various applications is well outlined.
Cost for setting up a Complete Cashew Nut Shell Liquid (CNSL) Extraction Plant
The Cashew Nut Shell Liquid (CNSL) Extraction Plant cost will vary depending on several factors. Each of these factors could have major effects on cost:
- What is the required Cashew Nut Shell Processing Capacity in tons of Cashew Nut Shell per hour (TPH)?
- How much Cashew Nut Shell Liquid (CNSL) do you want to produce per day?
Are You Looking to Start a New Cashew Nut Shell Liquid Production Line or Further Expansion?
