4. Setup

Follow these steps to set up your Rkazes Oil Press Machine before first use:

1. Unpack: Carefully remove all components from the packaging.
2. Clean: Wash the press chamber, press rod, hopper, oil cup, and filter screen with warm water and mild detergent. Ensure all parts are thoroughly dry before assembly.
3. Assemble:
   • Install the press bar and cover the top.
   • Insert the oil residue pipe into its designated slot.
   • Place the oil cup with the filter screen underneath the oil outlet.
   • Ensure the press chamber and rod are securely in place using the snap ring mechanism.
4. Placement: Position the machine on a stable, flat, and heat-resistant surface with adequate ventilation. Ensure there is enough space around the machine for safe operation and heat dissipation.
5. Power Connection: Plug the power cord into a standard 110V electrical outlet.

5.1 Preparing Raw Materials

Proper preparation of raw materials is crucial for optimal oil extraction.

• Dryness: Ensure all raw materials are thoroughly dry. High moisture content can affect oil yield and machine performance.
• Shell Removal: For materials like camellia seeds or olive seeds, remove hard outer shells before pressing.
• Crushing: For large materials such as walnuts, crush them into smaller pieces to facilitate pressing.
• Incompatible Materials: Do not attempt to press cocoa beans, spices, flowers, herbs, or coffee beans. The machine is not designed for these materials.

5.2 Hot Pressing vs. Cold Pressing

Your Rkazes Oil Press Machine offers two primary modes:

• Hot Pressing: For this method, materials are heated before or during pressing. This typically results in a higher oil yield and a richer aroma. The machine will preheat the press chamber to the set temperature.
• Cold Pressing: In cold pressing, raw materials are pressed directly without significant heating. This method helps retain the natural flavor and nutritional integrity of the oil, though the yield may be slightly lower.

Figure 7: Hot and Cold Pressing. This image visually explains the two pressing methods: Hot Pressing (heating first for rich aroma and high yield) and Cold Pressing (pressing raw materials directly to retain natural flavor).

5.3 Operating Steps

1. Power On and Set Temperature: Press the 'POWER' switch. Use the 'TEMP. ↑' and 'TEMP. ↓' buttons on the intelligent control panel to set the desired pressing temperature (range: 104-464 °F / 40-240 °C). The first line on the left display shows the real-time temperature, and the second line shows the set temperature.
2. Preheating: The machine will begin to preheat. The countdown display on the right will show the remaining preheating time. For optimal results, allow the machine to preheat for approximately 8 minutes (110V 850W). Do not add raw material to the hopper during preheating.
3. Start Pressing: Once preheating is complete and the countdown finishes, press the 'PRESS/STOP' button to start the pressing process.
4. Feed Material: Gradually add the prepared raw materials into the hopper. Observe the oil and residue output. Once a normal flow is established, you can continue to add more material.
5. Monitoring: The intelligent panel allows real-time monitoring of the current temperature. Adjust as needed for different materials.
6. Stopping Operation: To stop the machine, press the 'PRESS/STOP' button. If material remains in the press chamber, you can press the 'Rever' (Reverse) switch for a few seconds to reverse the press rod and clear any blockages, then press 'PRESS/STOP' again to stop.
7. Oil Collection: The extracted oil will flow into the oil cup. Freshly pressed oil may appear turbid due to protein content. It is advisable to let the oil settle for 8-10 hours to allow the oil and impurities to separate before use.

6. Cleaning and Maintenance

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

1. Cool Down: After use, press the 'CLEAR' button several times to clear residual material. Turn off the power and unplug the machine. Allow the press chamber and rod to cool completely before handling.
2. Disassembly: Once cool, take out the hopper and open the front cover. Remove the press rod and press chamber.
3. Cleaning: Hand wash the press rod, press chamber, hopper, oil cup, and filter screen with warm water and the provided cleaning brush. Use mild detergent if necessary.
4. Drying: Ensure all parts are thoroughly dried before reassembling or storing to prevent rust.
5. Storage: Store the machine in a dry, well-ventilated place away from direct sunlight.

Caution: The main unit is NOT dishwasher safe. Only hand wash removable components.

7. Troubleshooting

If you encounter issues with your Rkazes Oil Press Machine, refer to the following common troubleshooting tips:

• Machine Not Starting:
  • Check if the power cord is securely plugged into a working outlet.
  • Ensure the 'POWER' switch is turned on.
  • Verify that all components (press chamber, rod, hopper) are correctly assembled.
• Low Oil Yield:
  • Ensure raw materials are completely dry. High moisture content reduces yield.
  • Check if the correct temperature setting is used for the specific material. Hot pressing generally yields more oil.
  • Verify that the raw materials are compatible with the machine and properly prepared (e.g., crushed if large).
• Oil Not Flowing / Blockage:
  • Press the 'Rever' (Reverse) switch for a few seconds to clear any blockages in the press chamber.
  • Ensure the oil residue pipe is not clogged.
  • Clean the press chamber and rod thoroughly after each use to prevent residue buildup.
• Unusual Noise:
  • Stop the machine immediately.
  • Check for any foreign objects in the press chamber or hopper.
  • Ensure all parts are correctly assembled and tightened.
