4. Setup and Assembly
The Reber N.3 10900N is designed for easy assembly. Follow these steps to prepare your tomato press for use:
- Unpack Components: Carefully remove all parts from the packaging. Verify that all components listed in Section 3 are present and undamaged.
- Clean Parts: Before first use, wash all parts that will come into contact with food (funnel, cone filter, propeller, drainer, splash guard) with warm soapy water. Rinse thoroughly and dry completely.
- Attach Body to Motor Unit: Securely attach the cast iron body to the motor unit according to the manufacturer's instructions. Ensure it is firmly locked in place.
- Insert Propeller: Carefully insert the acetal resin propeller into the cast iron body.
- Position Cone Filter: Place the stainless steel cone filter over the propeller.
- Attach Funnel and Drainer: Mount the funnel onto the top of the body and position the drainer/collection tray underneath the filter outlet.
- Install Splash Guard: Attach the splash guard to the funnel to prevent splattering.
- Placement: Place the assembled unit on a stable, flat, and clean surface.
5. Operating Instructions
Follow these steps for efficient tomato processing:
- Prepare Tomatoes: Wash fresh tomatoes thoroughly. For best results, you may blanch and peel tomatoes, and cut larger ones into smaller pieces to fit the funnel. Remove any hard cores.
- Connect Power: Plug the appliance into a suitable 220V grounded electrical outlet.
- Start Operation: Turn on the tomato press. The motor will begin to run, and the propeller will rotate.
- Feed Tomatoes: Carefully feed the prepared tomatoes into the funnel. Do not force tomatoes into the opening; allow the propeller to draw them in naturally.
- Collect Puree: The machine will separate the pulp from the seeds and skins. The smooth tomato puree will exit through the drainer, while the waste (skins and seeds) will be expelled from the end of the cone filter.
- Continuous Processing: Continue feeding tomatoes until all are processed. The machine can handle 70-140 kg per hour.
- Finish: Once processing is complete, turn off the appliance and unplug it from the power outlet.
Note: For optimal performance and to prevent motor strain, avoid overloading the machine. If the machine jams, turn it off immediately, unplug it, and clear the obstruction before restarting.
6. Maintenance and Cleaning
Proper maintenance ensures the longevity and hygienic operation of your Reber N.3 10900N Electric Tomato Press.
- Unplug: Always unplug the appliance before cleaning or performing any maintenance.
- Disassemble: Disassemble the parts in reverse order of assembly (splash guard, funnel, drainer, cone filter, propeller, cast iron body).
- Wash Food-Contact Parts: All stainless steel and resin parts (cone filter, funnel, drainer, splash guard, propeller) are dishwasher safe. Alternatively, wash them by hand with warm soapy water. Rinse thoroughly and dry immediately to prevent water spots or mineral buildup.
- Clean Motor Unit and Cast Iron Body: Wipe the motor unit and the varnished cast iron body with a damp cloth. Do not immerse the motor unit in water. Avoid abrasive detergents, as they can damage the finish.
- Protect Metal Surfaces: To protect metal surfaces from rust, ensure all parts are completely dry before storage. Applying a thin layer of food-grade mineral oil to stainless steel parts before long-term storage can also help.
- Storage: Store the clean, dry appliance in a cool, dry place, away from direct sunlight and moisture.
7. Troubleshooting
If you encounter issues with your Reber N.3 10900N Electric Tomato Press, refer to the following common problems and solutions:
- Appliance does not turn on:
- Check if the power cord is securely plugged into a working electrical outlet.
- Verify that the power switch is in the "ON" position.
- Ensure there is power to the outlet by testing with another appliance.
- Motor runs but tomatoes are not processed:
- Ensure the propeller is correctly installed and engaged.
- Check for any blockages in the funnel or cone filter. Turn off and unplug the unit before inspecting.
- Verify that the tomatoes are cut to an appropriate size and not too hard.
- Excessive noise or vibration:
- Ensure all parts are correctly assembled and tightened.
- Check for any foreign objects or blockages within the machine.
- Ensure the appliance is on a stable, flat surface.
- Poor separation of pulp from seeds/skins:
- Ensure the cone filter is clean and not clogged.
- The quality of tomatoes can affect separation; very soft or overripe tomatoes might yield different results.
