The process is
Colleccting pith
The coir fibre pith comes as a by-product when coconut husks are processed for the extraction of the long fibres from the husk. Coco peat is the binding material that comes from the fibre fraction of the coconut husk. Good quality pith is collected from the fiber factories and stored in a storage yard to ensure availablity of raw material throughout the year. Every batch of raw material is checked for EC and PH values and a database is maintained for further.
WAashing
Raw material is washed properly with clean water and EC is checked at every level of washing. Even level of washing on the raw material is another important factor which is kept in mind during the process.
Washed material is sent for drying only after it confirms with all the required parameters set by the Quality Control Department. It is at this step that extreme care is taken to ensure that the quality is as per expectation.
DRying
The washed material is spread for drying in the cement yards. Moisture is tested at this stage to ensure it is below the required level and that the material will be suitable for compression after screening.
Screening and customisation
The dried material is then processed on different machines to ensure that there are no foreign particles, stones and fine dust. The process involves using a sieving machine, and a winnowing machine to remove unwanted particles. It is at this stage that customer's specific requirements with regards to sieve size and fiber size are complied with. Regular testing is done at this stage for confirming the quality of the material.
