The oil extraction machine uses a purely physical pressing method, which can cold-press sesame seeds and corns as well as hot-press walnuts, olives, and macadamia nuts. The machine operates at up to 60 MPa, efficiently extracting oil while preserving nutrients and flavor.
Its hourly output varies from 12 to 180 kg depending on the model, with a controllable heating temperature between 70℃ and 90℃. The cold-press oil machine is easy to operate with a simple instruction manual. One person can operate 3-4 units at the same time.

Key advantages of the oil extraction machine
- Taizy oil press machine has a high oil extraction rate: 43%–47% for sesame seeds and 50%–60% for walnuts.
- The oil quality is excellent, using a cold-pressing process to maximize the preservation of natural nutrients and active compounds. It produces low-impurity, clear oil and high-value oil cakes.
- Equipped with an ultra-high-pressure system, its maximum pressure can reach 60 MPa, providing a continuous and stable pressing force, suitable for hard and soft oily materials.
- It can simultaneously perform both hot and cold pressing with a wide range of applications.
- This oil extraction machine uses a mechatronics design, has a low failure rate, a high degree of automation, and can be operated by one person.
Working principle of the oil extraction machine
This oil extraction machine operates based on the liquid static pressure transmission principle. Using Hydraulic oil as the pressure transmission medium, an ultra-high-pressure hydraulic system applies uniform pressure to the oil materials
Oilseeds are extracted through pure physical pressing, maximizing the extraction of natural oils without the addition of any chemical additives.
The entire system consists of a hydraulic power unit and a sealed pressing chamber, forming a closed-loop hydraulic circuit. This ensures that the hydraulic oil circulates continuously within the system, significantly extending the machine’s lifespan.
This system allows the machine to automatically control pressure during operation. When the pressure reaches 55–60 MPa, the machine automatically stops. After the pressure drops, the machine automatically restarts, ensuring efficient and safe oil extraction.
How to use the oil press machine?
Step 1: Turn on the power and check the indicator lights. (For first-time use, turn the machine on and off 10 times to purge air from the hydraulic system and set the heating temperature to 50–60°C.)
Step 2: Carefully lift the piston (do not exceed the safe height) and place a cotton filter pad at the bottom.
Add the roasted oil and place another cotton pad and the pressure plate.
Step 3: Start the machine and begin pressing. After 2–3 pressure cycles, remove the oil cake and slowly release the pressure.
Note: Before starting the next cycle, fully lower the piston. The oil filter bag usually needs to be replaced after a few uses.

| Possible cause | Solution |
|---|---|
| Foreign matter enters the pump, preventing the steel ball in the inlet valve from returning to its original position | The oil seal inside the hydraulic cylinder is damaged |
| Clean foreign matter inside the pump and replace it with clean hydraulic oil | Disassemble the manual valve on the pump station and clean the manual valve |
| The piston is severely worn | Replace with a new oil seal |
| Oil pipe joints are leaking, and the sealing is not tight | Replace sealing components and tighten bolts securely |
| The pressure gauge is damaged and the needle does not move | Replace with a new piston |
| The pressure gauge is damaged, and the needle does not move | Replace with a new pressure gauge |
