New small peanut oil press equipment operation manual

1.1 The new small peanut oil press can press soybean, rapeseed, cottonseed, sunflower seed and other oil crops. (peanut oil press equipment operation manual)

1.2 Before using the new peanut oil press, it is necessary to read the instructions carefully and be familiar with the performance characteristics and operation method of the machine.

2. Requirements for raw materials （peanut oil press equipment operation manual）

2.1 Oil and grease should be dried and purified before being pressed by peanut oil press. Raw materials should be absolutely dried and carefully selected.

2.2 The dust in the oil without careful selection will block the oil path of peanut oil pressing, and the sand will accelerate the wear of the parts and shorten the service life of the screw, rod and cake outlet.

2.3 Before pressing, pay attention to the treatment of the new flower oil pressing oil can get twice the result with half the effort, which is conducive to improving the oil yield and reducing the residual oil rate in the cake.

3. Operation and use steps (peanut oil press equipment operation manual)

3.1 Before Startup

3.1.1 Conduct a comprehensive inspection on the new florets oil press. All fasteners shall not be loose, and the handle shall rotate flexibly. When the pulley is rotated by hand, the moving parts should be normal without abnormal noise.

3.1.2 Loosen the locking nut of the new small peanut oil press, turn the adjusting screw counterclockwise, so that the cone of the extrusion screw is close to the cone of the cake outlet, and then turn the adjusting screw 2-3 mm clockwise, and then tighten the locking nut.

3.1.3 Connect the three-phase and four-wire power supply to the machine. After power on, the spindle should be counterclockwise rotation. In any case, the machine must be well grounded, otherwise it will not start.

3.1.4 Adjust the temperature controller to the required pressing temperature of 120℃-180℃(depending on the oil), and turn the heating switch to the heating position of the main engine to heat the machine. At this time, the green light on the thermostat goes out, but when the temperature rises to the set temperature, the red light goes out, and the machine temperature is automatically controlled and maintained at the set temperature. When the temperature is low in winter, turn on the heating switch of all heating positions of the main engine to heat the oil.

3.1.5 Press the button of the main motor (turn the main switch to the positive position), and the main engine will start to run. The direction of rotation should be counterclockwise.

3.2 Run-in

After the new oil press is installed, grind and squeeze for 4-8h. The method is to slowly feed the dry cake from the hopper and press back repeatedly to smooth the press chamber. Remember not to directly pour the material into the hopper at the beginning of grinding extrusion, but feed it by hand to prevent the extrusion screw shaft from getting stuck. If excessive feeding occurs, abnormal noise occurs in the extrusion chamber, or the extrusion screw shaft becomes stuck, stop immediately to remove the blockage, or start grinding after reassembly. It is strictly prohibited to pull by force.

3.3 After Startup

3.3.1 When pressing oil normally, the feed must be kept even, and too much or too little or idling must not be cut off. At this time, the machine load is normal, the operation is smooth, the sound is rhythmic. The cake is discharged smoothly and there is no residue in the low pressure section. There is a small amount of oil residue in the high-pressure section, but the proportion of oil residue in the oil is not more than 10%. The temperature in the press room can reach 150-200℃. The green smoke from the pie outlet should be discharged through the smoke pipe and through the shield. Hot cakes should be spread out in time, do not rush to pile or transport, otherwise there will be natural phenomena. When the continuous working time is long and the machine temperature is too high, cooling measures such as fan blowing should be taken.

3.3.2 When the pressed oil flows into the oil filter, press the vacuum pump button, the vacuum pump starts to operate, and the air in the oil filter will be withdrawn. The oil in the filter barrel of the oil press will be naturally pumped into the oil filter, and the oil residue will be isolated on the press cloth. After the press is completed and the oil is extracted, open the valve on the oil filter and stop the vacuum pump. Dry slag will form on the filter cloth. Use a scraper.

3.4 After the Shutdown

3.4.1 Stop feeding before shutdown, and then put a small amount of cake crumbs into the machine. Stop the machine when the remaining materials in the press room are exhausted and the cake outlet is no longer available. After shutdown, turn the adjusting screw clockwise for 1-3 turns, and then disconnect the power supply.

3.4.2 When the cooling lag of the pressing chamber cover occurs, the fritters will be hard as stones and difficult to clean. There are four ways to deal with residues:

To remove the oil residue from the new peanut oil press, slowly turn the handle and the oil cake will slowly come out of the press chamber.

Then use a knife to clean up the internal residue of the oil pressing machine parts, pay attention not to let the knife scratch the thread, which will cause the instability of the screw shaft. Then, clean the internal threads of the new small oil press equipment with hot water.

After cleaning, soak in hot water to soften naturally, and brush some tiny cake residue.
