Pasta Cooler Operation Procedures and Safety Guidelines
Pasta coolers (面食冷却器) are essential equipment in pasta production lines, designed to rapidly reduce product temperature after cooking or drying, bringing it to the desired packaging temperature. Proper operation ensures product quality, prevents mold growth, and maintains food safety standards.
Pre-Operation Equipment Checks
- Before starting, check whether the fans and cooling pipes are functioning normally.
- Set the cooling temperature (room temperature ±5°C) and wind speed appropriately to avoid noodle breakage or uneven cooling.
- Verify that the cooling water supply is sufficient and the water temperature is appropriate for the cooling process.
- Open the cooling machine's water inlet and outlet switches to ensure smooth water flow.
- Adjust the cooling water flow to achieve the desired cooling effect.
- Check all electrical connections and emergency stop buttons for proper function.
Cooling Operation
- Transfer the fried or dried pasta products into the cooler and adjust the conveyor belt speed so that the cooling time is controlled at 5–10 minutes.
- Ensure the product center temperature drops below 30°C to prevent mold formation after packaging.
- Observe the cooling effect during operation; if the temperature remains too high, check whether the fans are running properly or whether the cooling system is blocked, and address the issue promptly.
- Monitor the conveyor belt for smooth operation and ensure products are evenly distributed across the belt width for uniform cooling.
Cooling System Features
- Conveyor system: Equipped with a conveyor belt that transports the product while the ventilation system simultaneously cools it.
- Ventilation system: Consists of a Freon/glycol water heat exchanger and fans. The fans are controlled by an inverter for precise air cooling regulation.
- Accumulation capability: Features a collection surface that can accumulate up to 20 minutes of production time, keeping the product in a constant temperature and clean environment inside the cooler.
- Energy optimization: Consistently optimizes processing time to maximize energy utilization efficiency.
Cleaning and Maintenance
- Regularly clean dust and residual noodle debris inside the cooler.
- Check and clean fan filter screens to maintain optimal airflow.
- Cooling pipes require regular descaling to ensure cooling efficiency.
- The stainless steel structure with flushing ramps simplifies the cleaning process and reduces cleaning time.
- The bottom plate is tilted on the sides to facilitate discharge of washing water.
- Hinged, openable side panels facilitate easy operation and access for thorough cleaning.
Safety Precautions
- Operators must wear appropriate personal protective equipment when working near the cooler.
- Never reach into the machine while the conveyor belt or fans are in operation.
- When performing maintenance, always disconnect the power supply first and follow lockout/tagout procedures.
- Keep the area around the cooler clean and free of obstructions to ensure proper ventilation.
- Monitor for any unusual sounds or vibrations during operation, and stop the machine immediately if abnormalities are detected.
