Slurry Ice Machine: Injecting New Vitality Into Cold Chain Logistics

Slurry ice is made up of millions of ice “microcrystals.” Compared to other types of ice, ice particles are smaller in size and have a larger heat transfer area, so they cool faster. It is commonly used in a variety of industries such as the cooling and storage of fish, produce, poultry and other perishable products.

The principle of the slurry ice machine is to quickly cool and convert liquid water into tiny ice crystals through a specific refrigeration system and process, and mix them with a small amount of aqueous solution to form the unique form of liquid ice. Here are the detailed steps on how a slurry ice machine works:

Refrigerant cycle: The compressor in the refrigeration system sucks in low-temperature and low-pressure refrigerant gas and compresses it into high-temperature and high-pressure gas.
Condenser cooling: The high-temperature and high-pressure refrigerant gas enters the condenser, and through contact with the external cooling medium (such as water or air), a condensation process occurs, dissipating heat to the cooling medium, thereby cooling the refrigerant into a high-pressure liquid.
Expansion valve throttling: High-pressure liquid refrigerant enters the evaporator through the expansion valve. Under the throttling effect of the expansion valve, the pressure of the liquid refrigerant drops sharply, and the temperature also decreases.
Evaporative refrigeration: In the evaporator, the refrigerant liquid absorbs heat from an external heat source (such as water) and evaporates, thereby reducing the temperature around the evaporator. At the same time, water and refrigerant are mixed through mechanical stirring or other methods to form a fluid ice suspension.
Suspension circulation: After the fluid ice suspension is cooled by the evaporator, it is pumped back to the refrigerator for recirculation, thereby achieving a continuous refrigeration effect.

In this way, the slurry ice machine can quickly convert liquid water into slurry ice. This slurry ice has good fluidity and cooling effect, and is especially suitable for scenarios that require rapid cooling and preservation, such as food refrigeration and fishery. Preservation, etc. At the same time, the ice crystal particles of slurry ice are tiny and will not cause damage to the surface of the cooled object.

Characteristics of slurry ice machine
Cools quickly. Slurry ice is a blend of 25% flake ice and 75% water, a combination that provides superior cooling for valuable and perishable cargo, allowing them to cool down faster.
Strong wrapping properties. Liquid ice provides excellent product coverage and flows like water, allowing it to easily get into tight spaces and crevices. This feature ensures that all exposed areas of the product are cooled evenly and efficiently, and heat is quickly dissipated, resulting in faster cooling rates.
Low salinity. The liquid ice machine we produce adopts a low-salinity design, and the salinity of seawater liquid ice is only 2.5%. This innovation eliminates the brine replenishment tank required by traditional liquid ice systems, further simplifying operations.
Food grade material. When it comes to food safety, our liquid ice machines feature the same high-quality stainless steel components as our flake ice machines, ensuring you can easily meet all food safety standards.
Energy saving and environmental protection. Compared with traditional refrigeration technology, the liquid ice machine consumes less energy, reduces energy consumption, reduces carbon emissions, and meets the requirements of sustainable development.

As the application of slurry ice machines in the field of cold chain logistics continues to expand, it will bring new vitality and development opportunities to the cold chain logistics industry. Its high-efficiency and energy-saving features will further improve the efficiency and quality of cold chain logistics, and provide reliable technical support for ensuring food safety and quality. It is foreseeable that the slurry ice machine will become the mainstream technology in the cold chain logistics industry in the future and promote the sustainable development and progress of the industry.
