Hydraulic oil press machine / oil extractor / oil press machine

Hydraulic oil press machine

Hydraulic oil press machine is used to extract oil from peanut, soybeans, sesame, sunflower seeds,walnut, pine nut, almond etc, and boast high oil yield. With easy operation and various models, this oil press machines have been exported to many countries, greatly improving working efficiency compared with manual operating. This small hydraulic oil press machine press little materials per time(2-7kg) and the pressing time is short(8-12min) so it’s popular in large and medium cities.

In addition, different models have different pressing time(8-12min).It has the characteristic of simple process and easy maintain. This machine can make pure oil without seepage. The hydraulic oil press machine is mainly composed of a barrel, cylinder, handle, hydraulic handle, pressure relief valve, grease nipple, etc. Hydraulic oil press machine is made of high-quality metal materials to improve machine performance and ensure component service life.

Structure of oil press machine

Oil extractor consists of three parts, that is, driving part, electrical control, and main body.

The main body is composed of the based plate, vertical shaft, top plate, pressing chamber, oil pan, screw nut, etc. The cylinder can push the raw material that lies in the screw chamber to press. Finally, the oil flows out from the chamber and enter the container.

Driving hydraulic part is the main power driving source with advanced hydraulic pump. It consists of a driving shaft, worm gear, worm, gear pump, high-pressure pump, overflow valve, hand control valve, cylinder assembly, conduit couple, etc.

The electrical control part is composed of engineer, voltmeter, temperature control, and adjusting table, pressure gauge, power insurance, etc.

Advantage of the hydraulic oil press machine

  1. oil press machinery is equipped with faster pressing speed, and it can press oil by a short time.
  2. Machine isis able to bear high temperature without any cooling device even the oil temperature is above 65C.
  3. Lownoise, lightweight, small volume, low power consumption(can save at least 30% power compared with double plunger pump), and energy-saving.
  4. Due to the hydraulic device(high pressure), automatic control system and preheating temperature control, sunflower oil pressing machine has high oil yield with high quality.

5. Wide application

Hot press material: Sesame, flax, peanut, rapeseed, wheat germ, corn germ, etc.,

Cold press material: Walnut kernels, pine nuts, almonds, olives, macadamia nuts, camellia seeds, etc.,

Condiments: Pepper, mustard seed, etc.,

6.Good oil quality

Pure physical pressing with high oil yield. It will not produce temperature during cold pressing, therefore the organic components of the oil will not be destroyed. It has the characteristics of good oil quality, low impurity, and wide application range.

7.Easy to operate and high efficiency: Mechatronics design with a w failure rate. The high degree of automation, it needs 8-10 minutes for one time pressing. It has Beautiful appearance and is easy to operate. One can operate 3-4 sets.

Use of the machine hydraulic oil press machine:

  1. Turn on the power and check that the indicator is working properly. When using the machine for the first time, the pump station lever is placed in a horizontal position. Continuously turn on and turn off the machine ten times to evacuate the gas in the pump station. Turn off the machine and turn on the thermostat switch.
  2. Put the level to the vertical position, turn on the power. When the piston in the barrel is raised until the platen can be taken out, turned off the switch immediately.

Note: Do not raise the piston too high. Remove the pressure plate and do not move any other parts in the barrel.

  1. Open the top cover, put a cotton pad, then pour the fried material(or not fried material)into the barrel. Put another cotton pad and the pressure plate, then close the top cover. Finally, put the level to the vertical position, start the switch, and start the oil press.
  2. Under normal circumstances, the machine will automatically stop when gauge pressure reaches 55 ( 50 ) MPa, and it will automatically work when gauge pressure reaches 40MPa. Repeat 2-3 times. Turn off the switch. Put the level to the horizontal position for about 20 seconds and then re-position it to the vertical position. Open the top cover and the main switch. Take out the oil cake and put the level to the horizontal position. The machine can continue work when the piston declines to the bottom.

Note: The hose on the back of the machine is connected to the back pipe and pump station on the back of the main unit, which is to prevent the hydraulic oil from flowing out when the piston is raised too high.

Preoccupation of oil press machine

  1. Voltage is 220v or 380v.
  2. Users should have grounding protection measures.
  3. The hydraulic pressure is 55 MPa.
  4. The oilseed is with smoke will trigger the gas explosion.

5. If the sump gets blocked, the customer should use a thin blade or needle to clean it.

The hydraulic oil needs to be changed once a year, and hydraulic oil press machine should be off if you do not use for a long time.

Successful case of oil press machine

We delivered 4 sets hydraulic oil press machine to Austria last week, and he bought the model 6YZ-180. The following is the packing details.
