PALM FRUIT STRIPPER : Palm oil mills receive the palm fruits in the form of palm fruit bunches of 10 to 30 kg. weight. So first operation is to separate the palm fruits from the palm bunches. Separation of palm fruits by hand is very big drugery. But TINYTECH palm fruit stripper separates palm fruits from the bunches by easy mechanical process. Stripping operation is done by the beaters welded on all the four sides of revolving heavy square shaft of the stripper. When bunch is thrown on the revolving beater shaft, due to the action of beater, entire bunch is thrown up and is allowed to fall again and again on the revolving beaters. Thus palm fruits are separated and fall down through the screen which are collected by the bottom conveyor and is taken out from the outlet. Empty bunches are automatically pushed on the other end of the palm fruit stripper machine. TINYTECH stripper is capable of stripping off sterilised fruits as well as non sterilised fruits effectively. Stripping capacity is 2 to 3 tonnes per hour. So one stripper can provide separated palm fruits to two palm oil expellers.
NUT FIBRE SEPARATOR :
The mixture of the palm nuts and fibres is obtained as by product of the palm fruit expeller. It is essential to separate palm nuts from the fibres. It is done in the hand operated machine called nut fibre separator. It is inclined cylindrical type revolving machine heaving all around suitable size screen from which fibres can escape but palm nuts can not escape. So while travelling the mixture from upper end to lower end of the machine, all the fibres escape from the cylindrical screen while palm nuts are collected from the lower end of the nut fibre separator. Fibres are used in the boiler as fuel. Palm nuts are sold out to the palm kernel mills where they crack the palm nuts, get the palm kernels, crush the palm kernels and get the palm kernel oil.
OIL CLARIFIER :
Palm oil which we get from palm oil expeller is in fact in the slurry form having a lot of solid particles of sludge which is very difficult to separate from the oil. Many scientific methods have been used by the scientists. But the easiest way to separate the sludge from the oil is by adding a lot of water in the oil. As water is heavier and oil is lighter, oil comes upward on the top and thus clear oil is drained. For this purpose, equipment of two simple cylindrical vessels, one inside the another, has been devised. Crude oil is filled up in the bigger cylinder and smaller cylinder inside the bigger cylinder remains empty. After some hours, the oil comes upwards on the top. When further crude oil is added through the funnel which extends near to bottom, level of oil increases. So the clarified oil on the top falls into a smaller (i.e. inner) cylinder from the upper edges of the smaller cylinder which is of smaller height than outer cylinder. Then clarified oil collected into the smaller cylinder is taken out from the bottom. This oil is heated to remove the moisture and you get crude palm oil (CPO).
PALM OIL EXPELLER AND COOKING KETTLE :
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.
