- If the machine malfunctions, switch it off immediately and unplug it. Do not attempt to repair it yourself.
3. Product Overview
The YUEWO Electric Automatic Oil Press Machine is constructed from 304 food-grade stainless steel, designed for efficient oil extraction from various seeds and nuts.
Figure 2: Key features of the YUEWO Oil Press Machine. This image highlights the 304 stainless steel squeezer for high oil yield, a full copper core coil with alloy transmission gear for continuous pressing, and quick installation for ease of use.
Main Components:
- Hopper: For feeding seeds into the machine.
- Pressing Rod/Auger: The internal component that crushes and presses the seeds.
- Pressing Chamber: Where the oil extraction occurs.
- Oil Outlet: Where the extracted oil flows out.
- Slag Outlet: Where the pressed pulp (slag) is expelled.
- Control Panel: Features a red button for pre-heating and a black button for squeezing/reverse.
- Collection Cup & Strainer: For collecting the extracted oil.
4. Setup
- Unpack: Carefully remove all components from the packaging.
- Clean: Wash all removable parts (hopper, pressing rod, pressing chamber, collection cup, strainer) with warm, soapy water. Rinse thoroughly and dry completely before assembly.
- Assemble the Pressing Mechanism:
- Insert the pressing rod into the pressing chamber.
- Attach the assembled pressing chamber to the main unit.
- Secure the pressing chamber with the provided pin. Ensure it is firmly in place to prevent the auger from dislodging during operation.
- Attach Hopper: Place the hopper securely on top of the main unit, aligning it with the opening for the pressing mechanism.
- Position Collection Containers: Place the oil collection cup with the strainer under the oil outlet and a separate container under the slag outlet.
- Power Connection: Plug the power cord into a grounded 110V electrical outlet.

5. Operating Instructions
The machine supports both hot and cold pressing methods. Hot pressing generally yields more oil and is recommended for most seeds.
Figure 3: Step-by-step guide for the oil extraction process. It illustrates preheating, adding seeds/nuts to the hopper, and pressing the squeeze button to initiate oil extraction.
Control Panel Functions:
- Red Button (Pre-heat): Press "-" to activate pre-heating. Press "o" to turn off.
- Black Button (Squeeze/Reverse): Press "-" to start squeezing. Press "o" to turn off. Press "=" for reverse and clean up.
Operating Steps:
- Pre-heat the Machine: Press the red button to the "-" position to start pre-heating. Allow approximately 8 minutes for the machine to reach the optimal temperature. The maximum temperature can reach 752°F.
- Prepare Seeds: Ensure seeds are dry and clean. For some larger nuts like peanuts, it may be beneficial to lightly roast them or remove their skins for better oil yield.
- Start Pressing: After pre-heating, press the black button to the "-" position to begin the squeezing process.
- Feed Seeds: Slowly add the prepared seeds into the hopper. The machine will automatically process them.
- Collect Oil and Slag: Oil will flow from the oil outlet into the collection cup, and the residual slag will be expelled from the slag outlet.
- Completion: Once all seeds have been processed and oil flow stops, press both the red and black buttons to the "o" position to turn off the machine.
Figure 4: This graphic provides estimated times for oil extraction: 8 minutes for prep heat, 30 seconds for cook time, and 60 minutes for continuous work time, applicable for 20 different types of seeds.
Recommended Seeds and Oil Yield:
The machine is suitable for a variety of seeds, including but not limited to:
- Sunflower seeds, Walnut, White/Black sesame
- Almonds, Camellia seed oil, Olive kernels
- Flax seeds, Linseed, Tea seed, Sunflower kernels
- Peanuts, Rapeseed, Perilla seeds, Pumpkin seeds
- Soybean
Oil extraction rates vary by seed type, typically up to 60% for some seeds. For example, peanuts can yield 40-42%, black sesame 48%, walnuts 60%, and flaxseed 40%.
6. Maintenance and Cleaning
Regular cleaning ensures optimal performance and longevity of your oil press machine. Always unplug the machine before cleaning.
- Cool Down: Allow the machine to cool completely after use before attempting to clean. The pressing chamber can remain hot for a significant period.
- Disassemble: Remove the hopper, pressing chamber, pressing rod, and collection cup.
- Clean Components: Wash all removable parts with warm, soapy water. Use the provided cleaning brush to remove any residual oil or seed pulp from the pressing rod and chamber. Rinse thoroughly.
- Clean Main Unit: Wipe the main unit with a damp cloth. Do not immerse the main unit in water.
- Dry Thoroughly: Ensure all parts are completely dry before reassembling or storing to prevent rust and bacterial growth.
- Reverse Function: The black button's "=" setting can be used for a brief reverse action to help clear minor clogs before full disassembly for cleaning.
Product Care Instructions: Hand Wash Only for removable parts.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Machine does not start. | Not plugged in; power switch off; power outage. | Check power connection; ensure switches are in the correct position; check circuit breaker. |
| No oil or very low oil yield. | Seeds are too wet; insufficient pre-heating; incorrect seed type; machine clogged. | Ensure seeds are completely dry; pre-heat for the recommended 8 minutes; verify seed suitability; clean the pressing chamber and auger. |
| Loud screeching noise during operation. | Auger not properly lubricated; initial dry run. | This can occur during the initial stages of pressing. Ensure some oil is present to lubricate the auger. If persistent, check for blockages. |
| Auger comes out during operation. | Retaining pin not inserted or improperly secured. | Ensure the retaining pin is fully inserted through the pressing chamber and main unit to secure the auger. |
| Machine stops unexpectedly. | Overheating (motor protection activated); severe clog. | Allow the machine to cool down for at least 15-30 minutes. Clear any blockages. |
| Oil contains too much particulate. | Strainer mesh too large; fine particles from seeds. | Use a finer mesh strainer or allow the oil to settle in a tall, narrow container for several hours, then decant the clear oil. |
