How to improve the capacity of cold chain storage

Cold chain storage is the act of using temperature control facilities to create a suitable temperature and humidity environment and store and preserve goods. It is also a low-temperature storage process based on refrigeration technology and refrigeration technology. If the control of the cold chain warehousing process is not accurate enough, it will lead to a decrease in product quality, changes in organizational structure, damage during collision and compression, and microbial proliferation. Therefore, it is necessary to improve cold chain warehousing solutions, so that enterprises can find the best balance between operating costs and quality control, in order to fully guarantee product quality and create sustained value growth for customers.

Unitization and standardization of cold chain warehousing

The cold chain warehousing system mainly includes unit appliances such as pallets, various shelves, handling equipment, temperature and humidity monitoring systems, and management information systems. Standardizing the loading unit and integration unit of cold chain warehousing, including the packaging unit size of shelves, pallet size, and other supporting facilities, is the basis for determining the entire cold chain standard.

Cold chain warehousing has high requirements for storage equipment and environment. When planning and designing cold chain warehousing systems, the non-standard and customized loading and integration units of cold chain warehousing are directly related to the technical dimensions of all cold chain docking facilities.

They are one of the basic technical data sources for the design and planning of cold chain warehousing facilities, which directly affects the establishment, planning, design, and optimization of warehousing system solutions, the capacity of storage equipment warehouses, and the operational efficiency of their handling equipment. They are also not conducive to warehouse management and operation services between third-party cold chain enterprises. Therefore, achieving unitization and standardization of cold chain warehousing can achieve optimal resource allocation, allowing the cold chain warehousing system to provide satisfactory services to customers while reducing the total cost of logistics systems and achieving the best economic benefits.

Control elements in cold chain warehousing environment

The control elements in the cold chain warehousing environment include product characteristics, cold chain warehousing equipment, processing technology, and operation management

1. The control elements in terms of product characteristics include raw material quality and storage resistance. There may be differences in storage temperature conditions, cooling methods, and unit packaging requirements for different raw materials. The quality change of refrigerated products mainly depends on the adjustable range of temperature controlled by the thermometer, the temperature influence of stored items, and even the temperature gradient between the surface temperature and the internal temperature of stored items can affect their quality. There is evidence to suggest that food exposed to room temperature for 1 hour may experience quality loss equivalent to half a year of storage at -20 ℃.

2. The control elements of cold chain storage equipment include: the quantity, quality, layout and control management mode of cold chain storage equipment in the warehouse, temperature and humidity monitoring system and management operation platform, low-temperature environment, and preservation storage and transportation tools. Select suitable cold chain storage equipment for refrigeration and freezing methods and processes to ensure that the cold chain storage environment meets environmental temperature, humidity, gas composition, hygiene and other requirements.

3. The control elements for processing process conditions include: the process level of cold chain warehousing, packaging conditions, and cleanliness and hygiene level.

4. The control elements of human factors include management mode, express delivery operation, and care for food.

5. The factors that affect the refrigeration or freezing effect also include the biochemical characteristics of stored items, cooling methods, and refrigeration process conditions. For example, manually adjusting the ratio of oxygen and carbon dioxide in the cold chain storage environment can slow down the physiological effects and biochemical reactions of fresh products, and extend the shelf life of stored items.

Among them, some factors are interdependent, such as the conditions of cold chain storage equipment, which directly affect the processing technology, management, and operation process.

 Design and Planning of Steel Structures for Cold Chain Storage Shelves

Through the design and planning of the shelf structure in the cold chain storage environment, analyzing the focus of equipment design and planning related to cold chain storage, strictly controlling each influencing factor, fully leveraging the performance advantages of each equipment, and utilizing the characteristics of different equipment to complement each other, from the perspective of the overall cold chain storage system, optimizing, rational layout and management, achieving the best operational efficiency of cold chain storage, and serving the entire cold chain system.

1. Determine the specific type, size, connection, structure, etc. of the shelf steel structure;

2. Identify the structural influencing factors at the beginning of the steel shelf structure design and planning;

3. The design and planning of cold chain steel shelf structures should have a systematic and developmental perspective;

4. Other details of the design and planning of the cold chain steel shelf structure.

Based on the confirmed cold chain storage steel shelf structure planning scheme, reasonably layout temperature and humidity monitoring nodes, signal feedback wiring, lighting system, handling system, etc., establish a complete operation monitoring system and management operation platform, reasonably allocate storage and freight, establish a reasonable storage operation environment, inbound and outbound frequency and sequence, and ensure the quality and efficiency of cold chain storage.

How to choose a cold chain warehousing solution

The main business of a normal temperature cold chain logistics center includes warehousing and storage, preliminary processing, product display, etc. The operational functional areas include tally area, temporary storage area, normal temperature area, cool area, refrigerated area, low-temperature freezing area, display area, circulation processing area, picking area, waste concentration area, business area, etc. It is necessary to analyze the functional areas, equipment layout, logistics direction, and operation process of the cold chain logistics center. Based on the logistics data analysis between each functional area, identify areas with frequent internal logistics and areas with relatively less logistics, determine the closeness of each operational functional area, and combine the available area of the operating unit to design a reasonable layout and simulate operation to determine a relatively reasonable cold chain warehousing solution. The steel shelf structure and its type are one of the key application technologies, which directly determine the warehouse storage capacity, the shortest and longest storage period of incoming items, turnover rate, and operational efficiency.

At present, the most common steel shelf structures in cold chain warehousing systems include: entry type shelves, push back type shelves, gravity type shelves, electric mobile shelves, loft type shelves and their logistics platforms, shuttle type shelves, automatic three-dimensional warehouses, and other dense storage systems. In addition, according to the characteristics of stored items, warehouse structure, and operation mode, ground stacking storage, stacking and stacking storage forms, or other low-density storage shelf structures can be adopted, such as tray type shelf structures, cantilever shelf structures, etc. The primary criteria for evaluating cold chain warehousing solutions are suitability, efficiency, and feasibility, meeting customer needs, followed by the economic viability of the cold chain warehousing solutions themselves.

By comparing or reasonably integrating the advantages of various cold chain warehousing solutions, and based on the operational results of actual cases, appropriate evaluation indicators for the solutions are established.
