Spiral Oil Press Operation Precautions

1. When the screw press is running, the treated preforms are squeezed from the hopper into the oil press. Under the action of the screw thread rotation, the feeding end is gradually pushed toward the cake end. The volume of each section in the squeezing is gradually reduced;

2. Because the screw thread continuously pushes the blank into the press, the pressure of the product is pushed forward, the embryo is compressed, and the oil is squeezed out. The common faulty material is squeaking in the squeeze cage of the low-pressure press, causing the entire oil press to vibrate;

3. The cake can not be broken into pieces and is dark brown with focal spots;

4. The power motor load current is higher than 30 amps;

5. The oil discharge position is moved to the direction of the cake, and the cake outlet is green smoke, the oil is reduced, and the oil color is dark brown.

If the above phenomenon lasts for too long, it will cause major mechanical damage. At this time, it is necessary to immediately reduce the steam pressure, increase the direct steam injection amount in the upper steaming cylinder, close the small material discharge door, reduce the feeding to the squeeze cage, increase the thickness of the cake, and gradually reduce the load of the press, and then add Adjust to return to normal working condition.
