Instructions of oil press machine
The operation steps of the new oil press can be divided into four parts: before starting, before pressing, pressing, before stopping. It can improve oil rate and quality when you master the use technology of the new oil press machine.
- Before starting the machine: adjust the gap between the screw shaft and the cake at first, so that the axis of the screw is pressed forward to the edge of the cake, and then turns backward 2-3 circles so that the gap is controlled at 0.5-1.0mm.
2.Before pressing: the oil press machine should be rotating for 3-5min without material, then put the oil cake or raw materials into machine slowly evenly, make the machine is heated. When the material is dry, the temperature of the body can be higher, otherwise will lower. The body of machine temperature is 70-80℃ before the oil press machine start work.
3.During the pressing process: The thickness of the oil cake should be adjusted slowly. The material is different, the frequency of presses is also different, and the thickness of the cake should be controlled between 0.25-0.5mm generally. When the machine work is good, you can pull the lever to lock the adjusting nut to increase the quantity of material. If the cake is not smooth or the cake is stopped, should stop put material in oil press machine, the adjustment plate should be taken out, the feeding port should be excluded, and then the spindle should be slowly removed to the blockage in the pressing. When pressing oils with high oil yield such as sesame and peanuts, it can be squeezed in batches two or three times, and each batch is suitable for 5 kg.
4.When machine is working: Every part that needs lubrication should be added oil 2-3 times. wipe off the oil on the surface of the machine every day. After working for about 3 months, the two bushings of the drive shaft should be cleaned, the bearing should be filled with oil, and the concentricity of the screw shaft and the press boring should be adjusted. The screw shaft and the cake ring should be replaced if the wear of the screw shaft is serious; When the wear is up to 2 mm, it can be used for changing the surface. If both sides of the oil press equipment are worn, the strip must be changed.
It is necessary to use a wooden rod to diligently feed the inlet to prevent the material from being blocked, to ensure uniform feeding, and to remove the slag in time, and the recovered oil residue can be put back into the hopper to continue pressing.
5.before the shutdown: should stop feeding new materials, but need to discharge all the residual cake in the squeeze before you can increase the gap between the cake, so that the excess oil residue in the squeeze. After the shutdown, the screw shaft should be pulled out to clean the squeezing and the residue in each gap in time to avoid forming a hard block and affecting the next work.
