Container Freezer Room for Ice Cream

The real challenge in transporting ice cream lies not in simply lowering the temperature to a very low level, but in avoiding repeated temperature increases throughout the entire process, from loading, closing the container, long-distance transportation to transfer. After significant temperature fluctuations occur, the ice crystals inside the ice cream may change, ultimately resulting in a coarser texture and altered structure. Therefore, when designing Container Freezer Room for Ice Cream, we not only consider the lowest temperature of the refrigeration unit, but also take into account the insulation of the container body, the sealing of the door, the air flow organization, the stacking of goods, and temperature monitoring for an overall design.

core temperature

The operating range of the equipment is from -22℃ to -25℃, and the temperature control accuracy can reach ±1℃. Compared with merely focusing on "how low the temperature can be reduced", we place greater emphasis on the stability during the low-temperature operation process. The high-precision variable-frequency refrigeration unit, in conjunction with the PLC control system, adjusts the operating status according to the changes in the box temperature, reducing frequent startups and significant temperature fluctuations. For long-distance transportation, it can also be equipped with full-process temperature recording and IoT remote monitoring, allowing for data to be available for checking the temperature changes during the transportation process.

cooling Capacity Maintaining

Sufficient cooling capacity does not mean that the inside of the container can always remain at a low temperature. If the insulation layer and the door seal are not well made, external heat will continuously enter, and the refrigeration system will need to constantly make up for it. Therefore, the container adopts ≥100mm high-density PU integral foaming insulation board with a thermal conductivity of ≤0.024 W/(m·K), and the door adopts a double-sealing structure, and a flexible door seal can be added. This structure is particularly suitable for cold chain scenarios with frequent loading and unloading, as it can reduce the impact on the container's temperature caused by the entry of hot air during door opening.

air current circulation

Ice cream is not as simple as just filling the container with the goods and then cooling them down. If the goods are stacked too densely, the stacking height is unreasonable, or if they directly block the air flow, local temperature differences may occur. Therefore, we will adjust the air flow organization inside the container according to the size of the goods packaging and the loading method. For non-standard projects, CFD air flow simulation and actual operation tests can be combined to optimize the air ducts, reducing local insufficient cooling and air flow dead zones.

Prevent recrystallization

"Anti-re-crystallization" cannot be achieved merely by lowering the set temperature. The re-crystallization of ice cream is also influenced by factors such as product formula, production freezing, packaging, and temperature changes during storage and transportation. Container refrigeration equipment mainly controls the temperature environment during the storage and transportation stage, with the focus being on reducing the occurrence of repeated heating-cooling cycles. At the same time, we can add internal structures such as anti-squeezing partitions and buffering supports based on the packaging form to reduce collisions and squeezes during long-distance transportation.

technical parameters

ex-factory test

After the equipment is manufactured, a 72-hour continuous operation test is conducted, simulating full-load conditions and large temperature differences both inside and outside. The focus is on observing the low-temperature operation state and temperature stability. At the same time, the airtightness and waterproofing of the box are inspected, and the cold air distribution inside the box is verified through CFD simulation and actual airflow tests.

Applications

Applicable to frozen foods such as ice cream and ice lollies: production factory → long-distance transportation → port transfer → cold chain storage → supermarket distribution. the container cold storage can be used as transportation equipment and, according to project requirements, can also serve as temporary mobile frozen storage space.
