1.SCRAPERS –Either manual or electric scrapers are used in domestic level while electric scrapers are used in medium or large scale industries .The function is scraping coconut to very minute shreds without addition of bran.
2.DEHYDRATORS- Drum Type Rotary Dehydrator.
Fuel is saw dust and combustion occur here.Water is sent through a pipe system in the boiler and saw dust is packed inside and subjected to combustion.Then water inside is boiled with no direct contact with saw dust preventing addition of impurities.Then the steam produced is sent through drum shaped rotary and coconut scraping are made to agitate and moisture is removed. Then remnant coconut scraping is obtained separately.
- · Domestic Machine-It can extract oil of only one coconut per once.Thus it is not efficient.
- · Medium Scale Machine 1-It can extract oil of 5/6 coconuts at once.It is suitable for medium scale industries.It is worth Rs 19 000.00 Capacity is 750g of scraped coconut.
- · Medium Scale Machine 2 –It can extract oil of 18 coconuts ,(2.2kg).It also is suitable for medium scale industry.It is Rs 85000.00 worth.It can be operatd by a hydrolic jak.
It runs by single phase current.It can extract oil of capacity of 700 coconuts a day.It needs an input of 15 kg scraped coconuts a day. It is operated by a motor.
4.DOUBLE BOILER-This is used for heating the scraped for 10-15 minutes.
