Safety Requirements for Using Direct Cooling Block Ice Machines in Ice Block Factories

At BAOCHARM, we not only sell high-quality big block ice machines, but we also provide comprehensive information to facilitate a safe and efficient operation. This article delves into the safety requirements for using a direct cooling block ice machine in an ice block factory, as stipulated by various GB/T standards.

General Requirements

Every block ice machine should comply with the safety requirements outlined in GB/T 5226.1. This ensures the machine's efficient operation and the safety of its operators.

Refrigeration System Safety

The safety performance of the refrigeration system of a block ice machine should meet the stipulations of GB/T9237. This guarantees that the cooling process is safe and reliable, contributing to the overall efficiency of the ice block manufacturing process.

Mechanical Safety

• The block ice machine's design should ensure reliable stability during normal transportation, installation, and usage. It should possess adequate mechanical strength.
• The machine should have protective covers or nets over parts that can be touched during normal operation and high-temperature components. This provides protection to operators, preventing contact with dangerous operating parts and high-temperature components during testing.

Electrical Safety

• Protection Against Electric Shock: The block ice machine's protection against electric shock should meet the requirements stipulated in GB/T5226.1.
• Temperature Limit: The temperature of the motor coil, measured using the resistance method when the block ice machine is supplied with the most unfavorable voltage within 90%~110% of the rated voltage range under the stipulated high-temperature operation conditions, should not exceed the temperature specified by the insulation level of the motor. The temperature of parts and shells that may be touched should not exceed 70℃, and other parts should not have abnormal temperature rises.
• Leakage Current: The leakage current of the exposed metal parts and power cord of the block ice machine should not exceed 0.75 mA as tested according to GB 4706.13.
• Electrical Strength: The block ice machine should not have puncture or flashover when a specified voltage is applied between live parts and the protective grounding circuit according to GB/T5226.1.
• Insulation Resistance: When a DC voltage of 500V is applied between the power circuit conductor and the protective grounding circuit of the block ice machine according to GB/T5226.1, the measured insulation resistance should not be less than 2MΩ.
• Grounding Resistance: The block ice machine should have a reliable grounding device and clear marking. It should meet the relevant regulations when tested according to GB/T5226.1.
• Safety Markings: The block ice machine should mark safety symbols (such as grounding symbol, neutral line symbol, warning symbol, etc.) in a conspicuous place in a way that is not easy to disappear.

Conclusion:

Understanding these safety requirements is crucial for any ice block factory utilizing a direct cooling block ice machine. Adherence to these standards ensures the safety of operators and the efficient running of the machine.
