When oil presser machine operation, good handling material from the hopper into the embryo virgin bore. In the next rotation of the pressing screw thread, and gradually the feed end to the cake side direction forward. So that within each segment volume virgin bore gradually narrowing; because of pressing screw thread continuously pressing the parison is pushed into the chamber, so that the front barrier pushed back to product pressure, compressed feed embryo, squeeze the oil out.
Before using the oil presser machine, first of all should be ready assistive devices and containers, check and adjust the belt tightness. Then start the motor, the machine idling about 15min, check the speed of pressing screw shaft. Usually the speed should be around 33dmin. Do you want to pay attention to the idling gear box gear meshing and sound normal, each bearing location and whether the motor is normal. Oil presser machine when idling, the motor current should be around 3A. The current is too high, should be immediately stopped to check and adjust after boot.
After Oil presser machine load properly, prepare about 50kg rapeseed or soybeans, ready to put into the hopper. Note: at the beginning of the press can not feed too fast, otherwise the juice inside bore a sudden increase in pressure, pressing screw shaft rotation does not move, causing blockage virgin bore, and even squeeze cage rupture, a major accident. So at the beginning of the compression, the feed should be evenly slowly put into the hopper, so that oil presser machine were running together. So repeatedly, continuous 3 ~ 4h or more, so that oil presser machine temperature gradually increased, and even risk of smoke (this is normal). When the press began to squeeze the chamber temperature is low, slowly twist the handle withered section studs, increasing the thickness of the cake, while increasing billet into juice moisture, temperature bore to be squeezed. It rose to about 90 ℃, after oil presser machine normal operation, the cake thickness can be adjusted to 1.5 ~ 2.5mm, and tighten the nut tightened.
After Oil presser machine functioning, high oil content of fuel oil are mostly concentrated in the bar at the front row and row round group. Article drain oil at 60% of the total amount of oil out of the front row at the group round about 30%; and the end of the drain oil is small, not a drip line, oil color is very clear. Repeatedly pressed two or three times to the best of Resources rapeseed or soybeans, during which can be uniformly doped materials embryos squeeze more oil diesel. To maintain uniformity when cutting, avoid erratic, otherwise it will affect the life of the oil press and oil yield.
Oil presser machine during operation should always check out the press cake cases and controls water blanks are neither too high nor too low. The cake should be a normal flaky, pressed by the screw shaft side smooth, the other side has a lot of hair pattern. As the cake loose weakness, or a shapeless cake, darker color, hand pinch Serve fragments, suggesting the billet add little water; as a cake weak, increased Cheng flake, or oil foam, Minga said that too much water. Under normal circumstances, no slag discharge between a round or rarely slag, slag in the bar at the discharge, such as slag was fine flaky described more water, the less water then the powder residue. In addition, the oil change position to see whether the water squeezed out of the right, when pressed into the water is too high or too low, the oil positions were moved back.
