Cashew Nut Shell Liquid Extraction Plant

Cashew Nut Shell Liquid (CNSL) is a versatile by-product retrieved from the Cashew Processing Plant. Cashew Shells are the outer shell of the Cashew Nuts which are part of the Cashewnut Fruit along with Cashew Apples. This shell contains viscous liquid, which is released on steaming of raw cashew nuts. This Cashew Nut Liquid is used to produce phenols after undergoing a De-carboxilation process.

Cashew Nut Shell Liquid Extraction Plant

CNSL resins have been used for many years in the manufcature of friction materials, contributing to the binding of the Constituents as well as friction enhancers in the form of dust obtained from the cured resin.

The shell of the nut is approximately 1/8th inch thick. Cashew nut shell liquid is the pericarp fluid of the cashew nut.

Natural CNSL is a mixture of phenolic compounds with aliphatic side chains and these are 70% anacardic acidm 5% cardonal and 18% cardol. CNSL is typically treated with high temperatures, which decarboxylates anacardic acid, yielding cardonal, additional distillation of CNSL rmeoves cardol leaving cardonal as the primary component in CNSL.

Different types of machines required in setting up a efficiently Cashew Nut Shell Liquid Extraction Plant (CNSL)

  • Shell Pressalso called as Expeller
  • Bucket Elevatorand Conveyor
  • Reaction Vessel
  • Wood Fired Steam Boiler
  • Screw Conveyor
  • Storage tanksfor liquid
  • Control Panel


This is mechical extraction process done using an Expeller, where cashew shells are fed via elevator to the expeller, which are crushed under force to release the liquid inside with strong force and de-oiled cashew cakes removed from other end.

This shell liquid is highly toxic and contains lot of impurities and also sulphur. It needs to be settled so the impurities are collected the bottom and liquid can be made ready for next process.
