Decorticating Or Cracking
The process of oilseeds extraction (crushing) is starting from the seeds decorticating or cutting or cracking. Oilseeds are decorticated or cut or cracked for the better quality of oil and cake (by product) as well for more recovery of oil. The groundnut decorticator shells the groundnut or coconut cutter makes the small pieces of coconut or palm nut cracker cracks the palm nut or soybean cracker cracks the soybean before crushing. While generally Sesame, Sunflower, Cottonseeds, Mustards, Rapeseed etc. can be directly crushed in the expeller without any shelling or cracking process.
Cooking The Seeds In Cooking Kettle
Decorticated or cracked oilseeds are fed in the feeding hopper of long cooking kettle for cooking purpose.
Cooking of seeds is necessary for highest recovery and long life of oils. Long cooking kettle is provided for the proper cooking of the oilseeds.
The cooking kettle has given a special shape for maximum heating surface and the better cooking.
The cooked oilseeds will be automatically dropped in the expeller and the expeller extracts (crushes) the cooked oilseeds with the highest extraction pressure and produces the oil and by product (cake).
The extraction chamber of expeller is specially designed for the highest recovery of oils; as well the complete design of expeller is heavy duty for the best performance.
The filter pump is attached with the expeller and it supplies the extracted oil from the oil tank of expeller to filter press with high pressure. The filter press filters the extracted oil by using the micro filter cloths to make it edible.
Filtered oil will be a very cleaned, transparent, fresh, pure and natural in taste without any chemicals and hence there is a big demand of the same oils at everywhere. The filtration chamber of the filter press is specially designed with membranes plates for the best performance.
The husk or any waste wood or any agricultural waste or diesel is used in the boiler for firing as a fuel.
The boiler produces the steam from the water and which is given to the cooking kettle for the cooking of the oilseed. Water feed pump is provided to feed the water in to the boiler.
