Advantages and precautions of automated three-dimensional cold storage
With the increasing demand for cold chain across the country, the construction of large-scale cold storage has begun to adopt high-rise building automated three-dimensional cold storage solutions. The traditional multi-layer cold storage that relies on manual and elevator transportation can no longer meet the needs of cold storage in the food low-temperature cold chain circulation system. It should have the functions of warehousing, sorting and packaging, and logistics and distribution. Automated three-dimensional cold storage, equipped with four-way shuttle, stacker, hoist, WMS storage management system, intelligent operation, reducing personnel working in the cold storage, here are some of the advantages and precautions of the cold storage:
Advantages of automated three-dimensional cold storage
1.The loading and unloading of the cold storage is managed by automatic equipment, and the operation of the refrigeration equipment is fully automated. There is no need for any operators in the warehouse, which saves labor costs.
2. It can ensure the first-in, first-out management of commodities, suitable for large-volume logistics warehousing, and can intelligently manage the commodities in the cold storage to reduce the loss rate in the warehousing process.
3. The automatic loading and unloading volume is large, the operation is fast, and the loading and unloading can be performed 24 hours a day, which overcomes the artificial physiological factors.
4. Computer management is adopted, and all data is stored in the computer, which is convenient for later management and maintenance.
5. Since no one enters and exits the three-dimensional cold storage, the opening and closing door is a double door setting. The size of the door is much smaller than that of the traditional cold storage. The opening and closing time of the door is reduced to about 30%, which greatly guarantees the stability and reliability of the temperature of the cold storage. Guarantee the quality of goods.
6. The three-dimensional fully automatic cold storage solves the problem of land cost, and is especially suitable for areas with scarce land resources, saving construction costs.
Other points for attention in automated three-dimensional cold storage
1. The initial investment cost is relatively large, and the technical level of operation and management personnel is relatively high. However, with the introduction and absorption of foreign technology, most of my country's low-temperature logistics facilities and equipment have been domestically produced, reducing the cost. The construction cost of the automated three-dimensional cold storage is greatly reduced, and the construction period is shortened.
2. Execution equipment such as racks, stackers, shuttles, conveyors and other equipment must adapt to the special requirements of the cold environment, avoid low temperature and cold brittleness, and ensure the reliability of cold starting and braking and cold operation.
3. The safety and reliability of electrical components under low temperature conditions are very important. The selection of components and the installation process will directly affect the use effect.
4. The heat convection caused by the entry and exit of the goods needs to be considered. There are many forms of heat loss when a three-dimensional cold storage is used: such as the intrusion of heat caused by the input of goods, the breathing of the goods, the lighting in the warehouse, the opening and closing of the warehouse door, and the circulation of heat formed by the entrance and exit passages, which will bring the temperature in the warehouse. The impact of changes, these factors must be considered in the cold storage design stage, and the size of the refrigeration model should be selected.
Automatic three-dimensional cold storage structure
Most of this type of cold storage is single-layer, with multi-layer metal shelves installed in the warehouse. The goods are stored in pallets and the pallets are loaded and unloaded by automatic tunnel cranes. According to the instructions of the electronic computer, they can be taken out of the specified shelves or put into the pallets of goods.
In the single-layer cold storage with prefabricated heat-insulating enclosure structure, there are multi-layer high shelves made of light steel, which are used for pallets for storing goods. They can be taken out of the specified cargo compartment or put into the pallet, and transported on a plane. With automatic operation of goods in and out of the warehouse.
The cold storage is equipped with an air cooler, which forms a low-temperature air layer in the upper space of the storage room, which is cooled by convection to maintain the set temperature in the storage.
