Industrial Block Ice Making Machine: Emergency Handling and Preventive Maintenance

In the realm of industrial cold chain logistics, food processing, and chemical production, the industrial block ice making machine plays a critical role. However, unexpected malfunctions may occur during operation due to equipment wear, environmental changes, or operational errors. Timely and proper response not only ensures production safety but also extends the service life of the equipment. In this article, we will detail common emergency scenarios and countermeasures for large ice block production systems, along with preventive maintenance recommendations.

Whether it's a 10 tons ice block making machine or a 15 tons industrial big block ice maker machine, the principle of making block ice relies on efficient refrigeration systems and stable mechanical operation. The direct cooling ice block machine, in particular, demands higher stability and maintenance. Understanding how to address emergencies can significantly reduce downtime and economic losses.

Common Emergencies and Immediate Responses

No Ice Formation or Abnormal Freezing

Causes: Refrigerant leakage, poor condenser heat dissipation, scaling in the water system (e.g., clogged filters), high ambient temperature, or insufficient refrigerant.

Response:

• Immediately shut down the machine and inspect refrigerant pressure. If leakage is detected, contact professional technicians for repair and refill.
• Clean dust and debris from the condenser vents to ensure proper airflow. Regularly descale water filters to prevent blockages.
• Adjust the installation location to avoid heat sources and direct sunlight. The recommended ambient temperature range is 10°C–35°C.

Failure in Automatic Ice Release

Causes: Malfunction of the de-icing solenoid valve, ice thickness sensor failure, heating system abnormality, or control circuit issues.

Response:

• Manually initiate the de-icing cycle. If the ice block does not release, check the solenoid valve’s power supply and coil for damage.
• Recalibrate or replace the ice thickness sensor to ensure accurate signal transmission. Test the heating element’s resistance and replace it if abnormal.
• Restart the equipment to resolve temporary circuit glitches. If problems persist, inspect the control board.

Overheating or High-Pressure Alarm

Causes: Fan failure, clogged condenser, overcharged refrigerant, or insufficient cooling water flow.

Response:

• Emergency shutdown. After the machine cools down, clean the condenser fins with compressed air or a soft brush.
• Check the fan motor for proper operation. Replace bearings or the motor if there is unusual noise or obstruction.
• Release excess refrigerant to restore standard pressure. For water-cooled models, inspect the water pump and pipelines for blockages.

Refrigerant Leakage

Causes: Pipe corrosion, cracked weld points, or aged seals.

Response:

• Shut down the system immediately and ventilate the area. Use a leak detector to locate the source.
• Temporarily seal minor leaks and arrange for professional repair, including pipe replacement or rewelding.

Electrical Failures

Causes: Aged wiring, insulation failure due to humidity, or overload.

Response:

• Cut off the main power supply. Use insulated tools to check for damaged circuits. Install dehumidifiers in humid environments.
• Measure the insulation resistance of motors and compressors. Replace components if necessary.

Preventive Maintenance Recommendations

To minimize emergencies, regular maintenance is essential:

1. Daily Cleaning: Keep the condenser, evaporator, and water filtration system clean. Remove dust, scale, and other contaminants to maintain heat exchange efficiency.
2. Periodic Inspection: Check refrigerant levels, electrical connections, and sensor accuracy every 1–3 months. Record operational data for trend analysis.
3. Environmental Management: Ensure the machine is installed in a well-ventilated, low-humidity area. Avoid exposure to high temperatures or corrosive substances.

Detail Maintenance Ensures Longevity of Block Ice Machine

An efficient industrial block ice making machine is the backbone of many industries. By understanding common issues such as refrigeration faults, electrical errors, and mechanical failures, operators can respond swiftly and effectively. Regular maintenance not only prevents emergencies but also enhances the longevity and performance of your large ice block maker machine.
