The "Standard 9 Bolt Expeller" is a bolt-type oil expeller with a 33"X7" chamber, rated at 200 kg/hour crushing capacity on 35 horse power at 28 RPM. It mainly presses mustard, flax, coconut, sesame, sunflower, peanut, canola, neem and camellia seeds, the screw squeezing oil from the seed inside the barred pressing chamber. The frame is painted bright green, with a round feed hopper and side feed chute on top, a bar-type pressing cage between square end posts and tie rods, a shaft extension at the drive end and Hindi lettering along the frame. It comes from a maker producing oil expellers since 1985.
