We have observed in Ghana that quality of oil through mechanical press is far better than oil from expeller. In mechanical press, only static pressure is given without any crushing and without any movement of material. So clean oil is recovered. While in expeller, a lot of rubbing and crushing movement takes place and hence a lot of sludge is created and it gets mixed with oil which becomes headache to separate. So entire clarification process is developed for mass production which is again water polluting process as 150% water is added in clarification process rendering entire water quantity polluted. In mechanical screw press, you can avoid clarification altogether. Expeller technology is simply for mass production which is mainly used for huge palm oil mills. For small scale production, mechanical screw press gives better results. But it is manual process. We should come out of the craze of automation. In fact our cooking kettle works very fine for sterilizing also. It consumes less power also.
Process in brief is as under :-
1. Palm fruits bunches is fed to stripper machine where palm fruits will be separated out and will be collected at bottom conveyor. Empties will come out at the opposite end which is excellent fuel for boiler.
2. This palm fruits will be cooked in steam cooking cum sterilizing kettle.
3. From kettle, it will be fed to Mechanical screw press where oil will be squeezed and you can get very clear red palm oil.
4. Oil thus produced will be filtered through a pump and thus you get very clear palm oil from filter press.
5. From mechanical screw press, you get mixture of nut and fiber which is to be dried under sun.
6. Then nuts and fibers can be separated out in nut fiber separator.Again fibers will be excellent fuel.
7. One steam engine of 30 hp will drive complete plant by belts, pulleys and counter shaft and also alternator 10KVA for electricity for any type of use for lighting, water pumping or selling to neighbours.
8. We have not offered expeller which produces mixture of sludge + oil and afterwards separation is a big headache. In big palm oil mills, separation is done by adding 150% water, but it is too much polluting process. One of our customer from Ghana (West Africa) informed us that he is very happy with mechanical screw press and he does not use expeller anymore. So based on his practical experience, we strongly suggest that above is a perfect offer to you.
PRODUCE YOUR OWN POWER FROM PALM WASTE & SELL IT
(Highly suitable for rural electrification by green power)
Tiny palm oil mill with sterilizing cum cooking kettles and mechanical screw press powered by steam is ideal combination. As a lot of fuel is generated in the process it self - about 23% empty palm bunches, 15% fibres and 6% palm nut shells, totally 44% fuel. If you process 10 tonnes a day, palm waste is generated up to 4.4 tonnes which is very much valuable fuel. If you use steam power, you will hardly consume 40kg fuel per hour. So at the most 1000kg in 24 hours. Thus you will have large surplus fuel almost 3.4 tonnes for generating extra power for rural electrification. If you want to run power house of 30hp engine, 20KVA alternator and boiler, it will consume one tonne palm waste in 24 hours. So you can run 3 such power houses round the clock from surplus fuel generated from your tiny palm oil mill. One such power house can give lights to 300 families for 6 hours at night and you can use power house for running industry such as maize milling, rice milling, water pumping etc for 18 hours. This much power production will be from free of cost fuel. So tiny palm oil mill is really blessing to the people.

NUT FIBRE SEPARATOR
If required, this crude palm oil can be filtered in TINYTECH oil filter press for better quality of CPO. For this purpose, oil pump is connected as integral part of the oil expeller with non return valves on both the sides. This oil pump sucks the oil from the oil tank and pushes to the filter press with heavy force. So oil is filtered in the filter press and you can get very clean filtered palm oil.
People in Africa, traditionally extract palm oil with simple hand opeated oil press. They separate the palm fruits by hand from the bunches and they carry to the traditional palm oil mill. Palm fruits are traditionally heated with water and sterilized into the asphalt drums by firing under the asphalt drum.
