The causes of the rise of cold storage
The cold storage door refers to the phenomenon that the cold storage door cannot be closed or opened smoothly due to various reasons, and its causes mainly include the following aspects:
1. Thermal expansion and contraction of frozen items: When the volume expansion of frozen items occurs during the freezing process, it will produce a thrust on the cold storage door, resulting in the phenomenon of expanding the door.
2. Temperature change of cold storage: When the temperature difference between the inside and outside of the cold storage is large, it is easy to cause the deformation of door frames, door bodies and other materials due to thermal expansion and contraction, which affects the normal opening and closing of the door.
3. Equipment failure: such as the failure of equipment such as ground wheels and door hinges, it may also lead to the failure of the cold storage door to open and close normally.

The impact of the cold storage door
The cold storage door not only affects the appearance and normal use of the cold storage, but also may bring the following effects:
1. Energy waste: The cold storage door cannot be closed tightly, which will lead to the loss of cold energy, and more energy needs to be consumed in order to maintain the internal temperature of the cold storage.
2. Damage to the quality of goods: The phenomenon of rising doors may lead to temperature fluctuations in the cold storage, which will affect the quality of stored items.
3. Safety risk: If the phenomenon of rising door is serious, it may lead to injury and property loss.

Strategies to deal with the rise in cold storage
In view of the causes and effects of the cold storage door increase, we can deal with it from two aspects: management and technology:
1. Management strategy:
(1) Strengthen daily maintenance: regularly inspect cold storage equipment and facilities, find and solve problems in time, and prevent the occurrence of door increases.
(2) Optimize inventory management: Arrange inventory reasonably to avoid excessive or too close accumulation of frozen items, so as to reduce the phenomenon of rising doors caused by thermal expansion and contraction of items.
(3) Establish an emergency plan: formulate an emergency plan for the possible phenomenon of rising doors to ensure that it can be dealt with quickly in an emergency.
2. Technical strategy:
(1) Improve the design of the door: use materials that adapt to the temperature difference, optimize the design of the door, and improve the sealing and deformation resistance of the door.
(2) Install temperature control equipment: install temperature control equipment on the cold storage door, monitor the temperature change and the opening and closing status of the door in real time, and take timely measures to prevent the occurrence of the phenomenon of rising doors.
(3) Application of intelligent system: the use of the Internet of Things, artificial intelligence and other technologies to achieve intelligent management of cold storage, improve the operation efficiency and safety of cold storage equipment.

Case study
A food processing plant in the use of cold storage process, there is a phenomenon of rising door, after analysis, the main reason is the thermal expansion and contraction of frozen items and cold storage temperature changes caused, in response to this problem, the factory has taken the following measures: strengthen daily maintenance, regular inspection of equipment and facilities; Optimize inventory management and reasonably arrange the stacking of frozen items; Improve the design of the door, improve the sealing and anti-deformation ability of the door, install temperature control equipment and apply intelligent systems, real-time monitoring of temperature changes and the opening and closing status of the door, after the implementation of these measures, the phenomenon of rising doors has been effectively solved, and the operation efficiency and safety of cold storage have been significantly improved.
Cold storage door is a common phenomenon in the process of cold storage operation, the operation and management of cold storage has brought a lot of challenges, this paper through the analysis of the causes and effects of cold storage door, put forward management strategies and technical strategies to deal with this problem, practice shows that by strengthening management and technological innovation, can effectively solve the problem of cold storage door increase, improve the operation efficiency and safety of cold storage.
