Automatic Oil Mill Plant

For Best Extraction, It Is Essential To Crush Oilseeds Twice.
First Crushing
During first crushing more steam heating is required. The residual oil content in the pre-pressed cake is about 12%-15%. After first crushing cake of about 10 mm thickness is sent to the second expeller machine where the second crushing takes place. You get about 80% oil during first crushing.

Second Crushing
Second crushing is done with more pressure by pressing cake discharge cone. Cake is thinner say 3 mm thickness. Residue in the cake is around 7% only. Now you get 20% oil. So full extraction is done after second crushing.

It is important for viewers to understand meaning of automation.

When process starts for seeds processing till feeding into the multiple expellers human labor was involved as human-being is best elevator and conveyer. If you have only have 1 decorticator and 1 expeller (MINI OIL MILL PLANT) two persons can handle this but when capacity of oil mill plant increase by more no. of expellers, it was remarkable that labors started exhausted due to monotonous work. So to give them relief conveyers and elevators were introduced for material handling and shifting from 1 equipment to the next equipment and so on. Thus, automatic plants came into action and started becoming popular.
