Loose palm fruits are fed to the cooking kettle. Palm fruits are cooked properly in the cooking kettle by means of steam which comes from boiler. Cooking kettle has jacketed bottom which is heated by the steam in the jacket. So palm fruits are properly heated. Moreover, some direct steam is added into the kettle which gets mixed with the palm fruits. So palm fruits are properly cooked in such a way that all cells of the palm fruits become ready to liberate the oil. Thus separate sterlisation process is not necessary in TINYTECH technology. In fact, sterlization process is done in the cooking kettle. Properly cooked palm fruits go to the crushing chamber cage of the palm expeller just below the cooking kettle. Cooking kettle is mounted on the palm oil expeller itself and is driven from the expeller shaft.
Worm shaft of the oil expeller pushes cooked palm fruits with the force into the crushing chamber which is a cage with thin long gaps all around the cage. Oil is liberated immediately due to crushing action and oil flows through the thin gaps and falls down into the bottom tank. Mixture of palm nuts and fibres is ejected from the side. Expeller runs on 7.5 HP electric motor through the reduction gear arrangement. It has capacity of crushing of 400 kg. loose palm fruits per hour.
