Working principle of grapefruit oil grinder: Jingjiang Weineng machinery when grapefruit enters the hopper, Under the effect of uniform fruit turning claw, it evenly enters into the oil grinding bin, and under the effect of several spiny oil grinding rods, it rolls and conflicts with the oil cells on the surface of grapefruit, and together under the effect of spiny hollow screw, it is transported to the discharge port; moreover, the machine is equipped with a spray pipe above the hollow screw, which can reduce the viscosity between grapefruit and grapefruit after the oil on orange is washed away by the water from the spray pipe It is convenient for grapefruit to roll and oil can flow into the oil collecting bucket smoothly. In order to avoid the spray hole blocking, stainless steel wire brush is installed in the spray pipe to dredge the spray hole in time.
