Analysis of steel shelf structure configuration for fresh-keeping storage of refrigerated storage fruits and vegetables
Storage equipment such as shelves has an important impact on the preservation of fruits and vegetables. When constructing a cold chain storage environment suitable for fresh-keeping storage of fruits and vegetables, it is necessary to construct standardized storage units for the category categories and unitized size series of storage items, reserve appropriate physical layout space for air convection, logistics, etc., and analyze the height of the building floor in the storage area. Factors such as the weight of the building floor and the uneven settlement of the ground, the construction and operation costs, the operating efficiency of the storage and handling equipment and its reliability configuration, etc., and the steel shelf structure size, node form, and component configuration are reasonably determined.
At the beginning of the steel shelf structure design and planning, the characteristics of the steel rack manufacturing materials, surface treatment process, load characteristics, structural influence factors and other details are selected, and the design selection and calibration evaluation are carried out according to the corresponding steel shelf design specifications and standards. Carry out the necessary test verification and evaluation without the design basis principle, reasonably design the structural connection nodes and components, ensure the strength, rigidity and stability of the steel shelf structure, and evaluate the design optimization and detail adjustment of the steel shelf structure. In order to meet the applicability of customer use.
The cold chain shelf for fresh-keeping storage of fruits and vegetables is generally based on the driving-in shelves and tray-type shelves, and then carefully built according to the characteristics of the fresh-keeping storage and storage of fruits and vegetables; the steel shelves must be able to withstand the low temperature and humid environment. Commonly used cold storage shelves include: drive-in shelves, press-in shelves, tray-type shelves (narrow roadway shelves), laminate shelves, electric mobile shelves, shuttle shelves, automated stereo libraries, and so on.
According to the functional division and layout of the fruit and vegetable storage area, the characteristics of the storage unit, etc., reasonably plan the shelf category, logistics direction, storage efficiency, and test and evaluate according to the temperature and humidity conditions of the actual application environment, and implement rational layout. And space adjustment, reasonable simulation and analysis of the consistency of fruit and vegetable storage in the steel shelf structure and the distribution of cold air flow, convection uniformity and temperature fluctuations should be as small as possible, to provide customers with cost-effective solutions and systems.
