In the modern cold chain logistics system, cold chain logistics doors play a crucial role, especially in large-scale warehousing, cold storage distribution centers, and other high-frequency use scenarios, where the number of door openings and closures can be as high as thousands of times a day. In the face of such a high frequency of use, how can we choose a reliable and durable cold chain logistics door to protect the stable operation of the cold chain system? This article will provide you with detailed answers.
Cold chain logistics doors open and close a thousand times a day, reality or challenge?
In the cold chain logistics industry, especially in places involved in fresh food distribution, vaccine transportation, and frozen food turnover, the switching frequency of cold chain doors is extremely high:
Frequent entry and exit of AGVs or manual labor;
Cross-operation in multi-temperature operation areas;
Strong demand for shipment, warehousing, and sorting in multiple bins.
If the cold chain door can not withstand high frequency of opening and closing, it will cause energy loss, temperature instability, and even affect food or drug safety.
Conclusion: Whether the cold chain logistics door can be used at high frequency depends on its structural design and the quality of core parts.
What kind of cold chain logistics door is suitable for high frequency use?
To cope with thousands of high-frequency switches every day, cold chain logistics doors need to have the following key elements:
High-speed switching drive system
High-quality servo motors can realize fast response and precise control, which can greatly improve the running speed of the door, with a common speed of 1.2m/s-2.0m/s, which can effectively reduce the loss of cold air.
Thermal Insulation Structure
Door curtains need to have highly efficient thermal insulation materials. Such as double-layer PVC curtains with filled thermal insulation cores, or use aluminum alloy framed door bodies with a breakaway design to ensure that the temperature is controlled within the set range.
Auto-sensing control system
Adopts geomagnetic induction, radar scanning, remote control, and Bluetooth multiple control modes to enhance the switching efficiency, adapt to the scenarios of pedestrian and vehicle mixing, and avoid the circulation of cold air for too long.
Why is it vital to choose a specialist cold chain logistics door supplier?
With hundreds to thousands of openings and closings per day. It is difficult for ordinary industrial doors to meet the performance requirements. A professional cold chain door supplier can provide a guarantee from the following aspects:
Customized size and structure-enhanced design, adapting to the temperature demand of different industries (food, biomedical, etc.);
High-frequency operation test, such as 500,000 times of trouble-free test, to ensure the long-term stability of the use of the door;
The fast response of after-sales maintenance service, supporting modular parts replacement, reducing the risk of downtime.
Common Cold Chain Logistics Door Usage Scenarios
Refrigerated warehouse: the temperature requirement is below -18℃, and the door body needs to have fast closing and super sealing.
Fresh food processing workshop: the area is frequently separated, high-speed switching is required to avoid air cross-contamination.
Pharmaceutical cold chain center: high GSP standard requirement, low temperature + clean double function door body.
Suggestions for cold chain logistics door selection
To ensure the stable operation of, cold chain, reliable equipment, safety, and energy savings, enterprises need to pay attention to the following points when selecting doors:
Confirm the average daily switching frequency and speed demand;
Account for the energy consumption and heat preservation efficiency of the door;
Select high-performance motors and control systems;
Evaluate the supplier’s technical solutions and service capabilities.
Conclusion: In high-frequency operation scenarios, it is more important to choose the right door for cold chain logistics!
Cold chain logistics door opening and closing thousands of times a day is not a difficult problem. As long as you choose the right products and suppliers, it will not only not be a bottleneck of the system, but also enhance the efficiency of the cold, chain, ensure the safety of the products, and reduce the cost of energy consumption. Whether you are a cold storage operator, a logistics platform, or a food/pharmaceutical factory. We recommend that you choose a high-performance solution that supports servo-motor fast doors, insulated cold storage doors and radar-sensitive fast doors to protect your cold chain logistics system.
