1. Sudden shutdown, the screw shaft is stuck
In the initial stage of pressing, the pressing chamber is not heated by a large amount of feed. Hot oil seeds (dry cakes with heated water) can be used to feed slowly, and the mill can be repeatedly milled to increase the temperature.
During the squeezing process, the squeezing chamber is broken, and then a large amount of material is fed, resulting in poor discharge and blockage of the squeezing chamber with oil. Therefore, the feeding should be continuous and even, and the cake should not be too thin. In the event of a failure, immediately turn off the power supply, insert the feeding regulating plate, stop feeding, open the discharge plate, reverse the screw shaft, and make it exit. Then remove the oil in the chamber and press again.
The oil has not been cleaned, and hard foreign objects such as stones and metals have entered the press chamber.
2. The oil press does not produce oil or the oil output rate is too low
Raw materials are not wet or too dry, damp and moldy, the seed material is not full, and it is caused by too much impurities. The oil must be re-cleaned and the moisture of the oil must be improved at a high speed.
The oil drain joint is blocked by oil residue or the pressing rod is assembled too tightly. The tightness of the sliver should be adjusted according to the oil content.
In the early stage of pressing, the temperature of the press chamber of the oil press is low, the output cake is too thin or too thick, and the parts are worn out, which will cause no oil or low oil output.
3. Too much scum
Individual slivers are bent or the gap is too large. At this time, you can remove the sliver, use gauze or whetstone to polish the three-convex square of the A-shaped sliver, straighten the sliver, and reinstall it. If necessary, pad some thin iron sheets to keep the gap within the range of 0.05-0.08 mm.
The plasticity of the oil is not good and it is difficult to produce the cake, which increases the pressure in the chamber. At this time, the oil should be mixed with water in an appropriate amount and milled to increase the temperature of the oil press to increase the plasticity of the oil.
The oil cake is too thin. The thickness of the cake should be appropriately increased according to the instructions.
4. The cake is not smooth
One of the reasons is that the thickness of the cake is not suitable, and the thickness of the cake should be adjusted; the second is because there are hard foreign objects such as dry cake, stones, iron, etc. entering the chamber of the machine, the machine should be shut down immediately, and the oil press should be squeezed out, and the cake should be inspected and removed. Dry cakes and sundries in the ring and the chamber. And according to the wear of the cake ring, repair or replace with new parts.
5. Oil return
It may be caused by blockage of the oil cracks of the oil press or the oil cracks are too small and the surface is not smooth. The former should be removed for cleaning, the latter should adjust the gap between the press and polish the oil seams with oilstone.
6. The oil press does not feed
If the oil has too much moisture, it should be sun-dried or fried.
The surface of the snail is not polished, so use emery cloth to polish the snail shaft or use dry residue to polish it. The sliver of the oil press is worn out, and the polygon of the sliver is destroyed, and the sliver can be turned over or damaged.
