About Innovator :

Having gone through a lot of struggle in life, he has come up a long way in his life. His technical knowledge deeply impressed a professor from MIT during a workshop of grassroots innovators at IIMA. Maximum international queries have been received for his technology at NIF and GIAN West. But being an incorrigible improviser, he is never satisfied and thus delays in delivery are a rule rather than exception. This affects the real demand of his technology. He has developed a lot of other machines for construction industry and other related industries.

Description :

Conventional oil expeller machines using screw press mechanism require more maintenance, space and energy than the design that he has developed.  This oil expeller, which can crush all kinds of seeds, uses planetary gear system coupled with screw press, saves power by 40 per cent when compared to the conventional oil expellers of the same capacity. It has higher production efficiency, which has been achieved by providing an improved and energy efficient transmission mechanism in a very compact design. Occupying just a third of the space of a conventional expeller, this machine is low on maintenance too. 

Advantages :
  • Saves space by 60% and electricity by 40% and thereby  reduce the operating expenses.
  • Perfect crushing ensures high quality cake without damaging its nutritive properties.
  • This machine contains 3 parallel crushing chambers driven by only one 50 HP motor.
  • The machine is made from special alloy steel which also reduces 20 to 30 % wear & tear compared to other conventional oil expeller.
  • Crushing chamber & other oil handling parts are made from special food grade steel.
  • The production of various dry oil seeds is given in following table
    Type of Seed HP of Motor Production in Metric Tons per 24 hour Oil Content in Residual Cake
    Mustard, Copra, Sunflower & Seasam 50 28-32 5 to 7
    Castor, Jatropha 50 28-32 5 to 7
    Cotton Seed 50 18-21 5 to 7
    Ground Nuts 50 23-26 5 to 7
    Palm Kernel 50 23-26 5 to 7
  • Above crushing capacity are calculated only for dry oil seeds and only single crushing.
