The "Young 9 Bolt Expeller" is a bolt-type oil expeller with a 30"X5.5" chamber, rated at 100 kg/hour crushing capacity on 15 horse power at 28 RPM; its size is also given as 30x5.5. 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 machine is painted dark green, with a large flywheel pulley, a feed hopper on top, a bar-type pressing cage between square end posts and tie rods, splayed stand legs and Hindi lettering along the frame. It comes from a maker producing oil expellers since 1985.
