3. Position the oil collection bowl with the filter underneath the oil outlet.
4. Ensure the residue outlet is clear and can discharge into a suitable container or bag.
5. Connect the power cord to the machine and then to a grounded 110V power outlet.

6. Operation

6.1 Preparing Raw Materials

• Ensure all materials are dry. If materials are damp or have high moisture content, it is recommended to lightly fry or microwave them for a short period before pressing to improve oil yield.
• For nuts, please remove the shell before squeezing.
• The machine is suitable for pressing mustard seeds, rapeseed, crushed peanuts, almonds, white/black sesame seeds, sunflower seeds, flaxseed, walnut seeds, perilla seeds, tea seeds, and more.

6.2 Preheating the Machine

Whether using cold pressing or hot pressing mode, the machine must be preheated first. The preheating time is typically 8-10 minutes.

1. Turn on the machine.
2. Set the desired temperature using the control panel (refer to Section 6.4 for temperature control).
3. Allow the machine to preheat until the set temperature is reached.

6.3 Cold Pressing and Hot Pressing Modes

This machine offers both cold and hot pressing modes. Choose the mode based on your raw material and desired oil characteristics.

Image 7: A visual comparison of Hot Pressing and Cold Pressing modes. Hot Pressing is shown to yield higher oil and be natural & pure, while Cold Pressing directly presses for natural flavor.

6.3.1 Cold Pressing

Cold pressing retains the natural flavor and maximum nutrients of the oil. It is suitable for materials where heat might degrade sensitive compounds.

1. After preheating, ensure the temperature is set appropriately for cold pressing (lower end of the range, typically 40-80℃).
2. Slowly feed the prepared raw materials into the hopper.
3. The machine will begin extracting oil. Collect the oil in the designated bowl.

6.3.2 Hot Pressing

Hot pressing maximizes oil yield and is ideal for many types of seeds. The machine utilizes high-temperature hot pressing for efficient extraction.

1. After preheating, set the temperature for hot pressing (higher end of the range, typically 100-210℃, depending on material).
2. Slowly feed the prepared raw materials into the hopper.
3. Collect the extracted oil.

6.4 Intelligent Temperature Control

The machine is equipped with an intelligent temperature control system to accurately maintain temperatures between 40-210℃ (104-410℉).

A graph above shows the temperature range from 104°F to 410°F suitable for various ingredients.

• Preset Temperature (1): Displays the temperature you have set.
• Current Temperature (2): Shows the actual temperature inside the pressing chamber.
• Set Up (3): Press to enter temperature setting mode.
• Pause/Start (4): Controls the operation of the pressing mechanism.
• Temp Down (5) / Temp Up (6): Adjusts the desired temperature.

6.5 Unsuitable Materials

Certain materials are not suitable for this oil press machine due to their hardness, low oil content, or consistency. Using these materials may damage the machine or yield poor results.

Image 9: A warning graphic indicating materials that are NOT FOR use in the oil press, specifically materials with high hardness or powder form. Examples include olive pulp, olive pits, coconut shreds, coffee beans, grape seeds, and castor seeds.

DO NOT use the machine for:

• Olive pulp
• Olive pits
• Coconut shreds
• Coffee beans
• Grape seeds
• Rice
• Castor seeds
• Any materials with extremely high hardness or very low oil content.

Additionally, the new machine should not first squeeze materials with hard texture and low oil content. Start with easier-to-press materials.

7. Maintenance and Cleaning

Regular cleaning and maintenance will ensure the longevity and optimal performance of your oil press machine.

7.1 Daily Cleaning

1. After squeezing oil, press the reverse button to reverse the screw for five seconds. This helps clear residual material from the chamber and rod.
2. Unplug the machine and allow it to cool down completely.
3. Remove the pressing chamber and screw.
4. Clean the chamber and rod with clean water or a mild detergent and the provided cleaning brush. Ensure all oil residue is removed.
5. Wipe down the exterior of the machine with a damp cloth.
6. Dry all components thoroughly before reassembling or storing.

7.2 Important Cleaning Notes

• DO NOT wash the main machine host with water. This can cause electrical damage.
• Only the removable parts (chamber, screw, hopper, bowl, filter) should be washed with water.
• Avoid using abrasive cleaners or scouring pads that could scratch the stainless steel surface.
