Common Problems and Solutions for Dry Ice Makers (Part 1)

Common problems and solutions for dry ice making machines are as follows:

1. Insufficient dry ice production output

Insufficient dry ice production output is a common problem for dry ice makers. This is often related to the properties of CO2: only cryogenic liquid CO2 can be converted into solid CO2 (dry ice). Most cases of insufficient output occur because some of the cryogenic liquid CO2 vaporizes into gaseous CO2 in the transmission pipeline, while the gaseous CO2 can’t be converted into solid CO2, resulting in insufficient output for dry ice machines. The cryogenic liquid CO2 supply pipeline should be insulated with good insulation materials or replaced with professional vacuum insulation pipeline. This is an effective measure to prevent vaporization during CO2 transportation, ensuring that the cryogenic liquid CO2 is effectively converted into a solid state upon entering the dry ice maker's solid-liquid separation chamber, producing a large amount of dry ice.

Also, the cryogenic liquid CO2 supply pressure is an influencing factor. This is related to the pressure of the CO2 storage tank and the size and layout of the CO2 supply pipeline. When arranging the CO2 pipeline, users can provide a site layout diagram and consult with the professional dry ice machine manufacturer for a scientific and effective CO2 pipeline layout.

2. Abnormal noise from the dry ice production machine

Abnormal noise from the dry ice production machine can occur for a variety of reasons. It could be a malfunction or leak in the CO2 solenoid control valve, which could cause explosions and the emission of large amounts of white smoke from the dry ice machine's ice outlet. The user can replace the CO2 solenoid control valve promptly. Alternatively, the hydraulic oil could contain impurities or deteriorate, causing abnormal wear on the dry ice machine's moving parts and causing abnormal noise. The hydraulic oil in the dry ice making machine should be clean, free of impurities and moisture. After the dry ice maker machine's initial operation, the hydraulic oil should be drained, clarified, and filtered. The hydraulic oil should be replaced after the dry ice machine has been running for 1500 hours.
