oil pressing machine

Brief introduction of oil extractor

It is a stainless steel oil extractor with one screw. The raw material can be soybeans, peanut, cotton seeds, rapeseed, olives, sunflower seeds, etc. Before the machine works, you should preheat the machine for about 20 minutes, and the temperature of the pressed peanuts is about 180℃. The thickness of the oil residue with a round shape can be adjusted. There are two pressing ways including hot pressing and cold pressing. Hot pressing means that operator fries the raw material in a pan before pressing oil. (High oil yield). Cold pressing means that the operator places the raw material into the oil pressing machine directly.

Oil pressing machine is equipped with two oil filters to simply filter impurities and fried residues, so the pressed oil can be eaten directly.

The structure of oil extractor

oil pressing machine mainly consists of five parts such as electric control part, the heating and pressing part, the adjusting part, the transmission part, and the vacuum filter oi part.

  1. The electric control part is composed of an air switch, AC contactor, temperature, control instrument, circuit automatic protection device.
  2. The heating and pressing part is composed of a heater, a pressing screwand the body.
  3. The transmission part is composed of the main shaft and the gearbox, the pulley, the motor wheel, etc.
  4. The speed adjusting part is composed of an adjusting screw, a regulating nut, a handle, and a locking nut, etc.
  5. The vacuum filter oil part is composed of the vacuum pump. oil filter tube and other assembly components.

Advantage of oil pressing machine

  1. High oil press rate.
  2. The final oil is very clean without any residue. Two oil filters can enable the cleanness of the final oil.
  3. Special screw structure is able to press oil with high efficiency.
  4. The oil screw press is suitable for different raw materials such as soybeans, peanut, cotton seeds, rapeseed, olives, sunflower seeds

How to install oil pressing machine?

  1. The oil pressing machine should be installed in enough space.
  2. Place the machine and oil filter horizontally.
  3. After installation, the 0.5-1m ground wire should be connected to the machine, and the gap between is 3-5m.

How to operate oil extractor? (1)

1. Carefully read the manual before working.

2. Before starting the machine, a comprehensive inspection should be conducted such as not loose fasteners, flexible rotation of the handle, rotating pulley by hand. All working parts should be normal, and then add lubricating oil to the gearbox.

3. Operator loosens the lock nut, and counterclockwise rotates adjustment screw, enabling that the conical surface of screw and oil residue shall be close. Then you can clockwise rotate the adjustment screw to 2-3mm and then rotates the locking nutso as to start the oil press machinery.

4. Open the door of the electric box. switch on the air switch (placed in a reasonable position) in the box, that is, the power of the whole machine is switched on.

5. Adjust the temperature of oil extractor to 150200 ℃(it is different according to different raw material ), and open the total heating switch to heat the machine, and the green light of the temperature controller is on at this time. The red light is on when the temperature of the machine reaches to the required one. Machine temperature is set automatically and keeps within set range.

6. It is necessary to keep the feeding evenly. The thickness of the oil residue is normally controlled at 0.5-2mm. The oil residue should be smooth, ensuring that the low-pressure section basically is no slag. A small amount of oil slag can exit in the high-pressure section, but the proportion of slag in the oil is not more than 10%. The temperature inside the pressing part can reach 105200℃, and the green smoke at the oil residue outlet should be discharged through the shield. The oil residue should be spread out in time. When the working time is long and the machine temperature is too high, the fan should be used to cool down(the heater can stop working when the screw oil press works continuously).

7. Press the forward button and the main unit starts to run. The rotation direction of the screw shaft should be counterclockwise.

8. When the squeezed oil flows on the filter oil, you should first check whether the vacuum pump motor rotates correctly. The vacuum pump starts to run when pressing the vacuum pump button. The air in the filter oil tank is drawn out, and negative pressure is formed in the barrel. The oil naturally flows into the filter drum, and the oil residue is isolated on the filter cloth. After the pressing is completed, the vacuum pump is stopped. the venting valve of the filter oil is opened, and the dry slag is formed on the filter cloth. The dry is removed by using a scraper to scrape off (can not scrape off if the negative pressure is formed in the barrel).

9. Prohibitfeeding before stopping the machine, and adjust the gap of oil residue. After the waste material is drained, the oil residue is no longer discharged. The adjusting screw is screwed out 1-3 rounds smoothly. Finally cut off the power.

The FAQ of oil extractor

  1. What’s the raw material?    The raw material can be soybeans, peanut, cotton seeds, rapeseed, olives, sunflower seeds
  2. can hot pressing press more oil?

Yes, of course, compared with cold pressing, hot pressing can get more oil.

  1. Does the finally contain much residues?

No, the oil pressing machine is equipped with two oil filter that can filter the impurities in the oil.
