Coconut Shell Flour


Coconut Shell Flour is made from the most versatile part of the coconut – the shell which is organic in nature. Since it has good durability characteristics, high toughness and abrasion resistant properties, it is suitable for long standing use. The shell is similar to hard woods in chemical composition though lignin content is higher and cellulose content is lower.

To manufacture coconut shell flour, the shells of fully matured nuts are first cleaned of the adhering pithy matter and broken down into small pieces. These pieces are then subjected to repeat grinding in grinding mills and the ground mass, after passing through cyclones and vibratory sieves fitted with phosphor-bronze mesh, are finally drawn out in different mesh sizes.
