What are the production requirements for small automatic block ice machines?The production of small automatic block ice machines must meet ten core requirements: sealing, electrical safety, energy efficiency, hygiene, automated control, modular design, environmental adaptability, materials and processes, ice removal efficiency, and noise control. A detailed analysis is provided below:
Sealing Requirements
Refrigeration System Sealing: The refrigeration system must be highly sealed, with an airtightness test pressure of no less than 2.5 MPa, to prevent refrigerant leakage and ensure efficient ice production.
Water System Sealing: The water system must be leak-proof and ensure smooth water circulation to prevent equipment damage or reduced ice production efficiency caused by leaks.
Electrical Safety Requirements
Leakage Current: Leakage current must not exceed 30 mA to ensure safe operation.
Ground Resistance: Ground resistance must be less than 0.1 Ω to prevent safety incidents caused by electrical failures.
Insulation Resistance: Insulation resistance must be greater than 2 MΩ to ensure good insulation performance of the equipment’s electrical components
Energy Efficiency Requirements
Energy-Saving Design: Direct heat exchange between the evaporator and the refrigerant is employed to improve heat transfer efficiency and reduce energy consumption. For example, using a special aluminum plate evaporator can achieve a heat transfer efficiency three times that of steel, saving 30% energy
Energy Efficiency Labeling: Equipment must be labeled with its energy efficiency rating to facilitate user selection of energy-saving products
Hygiene Requirements
Food-Grade Materials: Components in contact with water must be made of food-grade materials. For example, the surface roughness of aluminum alloy evaporators must be controlled to Ra ≤ 1.6μm to prevent bacterial growth and ensure ice hygiene
Microbial Limit Testing: The equipment must pass microbial limit testing to ensure that the ice-making process meets hygiene standards
Automation Control Requirements
Fully Automatic Ice Making/Defrosting: The equipment must have fully automatic ice making and defrosting functions to reduce manual operation and improve production efficiency
Remote Monitoring and Fault Self-Diagnosis: Equipped with a remote monitoring system and fault self-diagnosis functions, users can monitor the equipment’s operating status in real time and address any issues promptly
Modular Design Requirements
Modular Structure: The equipment must adopt a modular design for ease of installation, maintenance, and upgrades
Containerized Structure: Containerized structures have become the mainstream design. Each unit occupies a small footprint and supports modular installation, saving space.
Environmental Adaptability Requirements
Temperature Range: The equipment must adapt to varying ambient temperatures. For example, in industrial applications, the minimum operating temperature is required to be -25°C.
Humidity Control: The equipment must possess a certain degree of moisture resistance to withstand high humidity environments
Material and Process Requirements
High-quality Materials: Select high-quality materials that are corrosion-resistant, wear-resistant, and heat-resistant to ensure the equipment’s service life
Precision Processing: Utilize precision machining to ensure tight fit and stable operation of all equipment components
Deicing Efficiency Requirements
Fast Deicing: Under standard operating conditions, deicing time should not exceed 30 minutes, improving production efficiency. For example, companies like Botai Refrigeration have reduced their equipment deicing time to 25 minutes.
Uniform Deicing: Ensure that ice cubes are evenly detached to prevent breakage or residual ice
Noise Control Requirements
Low-noise design: The equipment must adopt a low-noise design, such as using a low-noise compressor and optimizing the air duct design, to ensure low operating noise and not affect the user experience
