What is the difference between cold chain logistics and general logistics management?

The applications of cold chain logistics include:Primary agricultural products:vegetables, fruits; meat, poultry and eggs; aquatic products, floral products. Processed food:Frozen food, poultry, meat, aquatic products and other packaged cooked food, ice cream, dairy products, chocolate; fast food ingredients. Special commodities:Pharmaceuticals, so it is a huge system engineering than the general room temperature logistics system is more demanding, more complex, and the construction investment is much larger. Due to the timeliness of perishable food requires high organization and coordination of all parts of the cold chain, the operation of the food cold chain is always related to the cost of energy consumption.

Compared with room temperature logistics, the main difference of cold chain logistics is that it needs to keep low temperature and the whole cold chain, which involves more disciplines, more complicated management and higher cost.

cold chain logistics has special requirements on time, quality, temperature, humidity, hygienic environment, complicated operation and three main features:.

1. Timeliness

As the product design carried by cold chain logistics is generally perishable or not easy to store, so we require cold chain logistics development must be able to quickly complete an operation to ensure the timeliness.

2、Complexity

Compared with room temperature logistics, cold chain logistics involves refrigeration technology, heat preservation technology, temperature and humidity detection, information system and product change mechanism research, some products even involve the constraints of laws and regulations, and each product is carried out in accordance with its corresponding temperature, humidity and storage time requirements, once the chain enterprise's efforts in the early stage go down the drain, it will greatly increase the complexity of cold chain logistics.

3、High cost

The cost of cold chain logistics is much higher than room temperature logistics. First of all, the cost of equipment is high. The cost of cold chain logistics center warehouses and cold chain delivery is generally several times that of room temperature warehouses and vehicles, and because it involves food and other special facilities and equipment, it requires a large amount of capital investment. Secondly, the operating cost of cold chain logistics is high. Cold warehouses require continuous refrigeration to ensure that the temperature is at a constant state, resulting in high power cost of cold warehouses; refrigerated vehicles also require uninterrupted cooling to ensure constant temperature of the products, which requires more fuel cost. Cold chain logistics has a long capital payback period, which is not affordable for general enterprises.

Tell us more about the application of our industry in the refrigerated part of the shelf equipment. Currently on the market more mature high-density storage racking technology are: insertion type racking, drive type racking, intelligent frame, electric mobile racking, shuttle truck racking.

These five types of shelves have their own advantages and disadvantages. The following analysis from the form of operation, unit cost of shelves, cargo depth of three aspects of a comprehensive comparison and description:.

1. Press-in rack management is also called backward racking, suitable for multiple varieties of goods in small batches for access. The operation design mode as well as the first in and the last out, the depth of learning of cargo information is usually ≤ 5.

2. The utility model is suitable for small varieties, large quantities of goods access. Using advanced access methods, in the side against the wall, the installation of rear beams and rear pull, conveying depth ≤ 6. In the middle of the region without the installation of rear beams, rear pull, goods in and out of the first-in-first-out or first-in-first-out cargo depth ≤ 12.

3. skillful fixing, suitable for small cold storage and irregular cold storage. The ingenious frame has its own characteristics:it can be stacked and assembled with each other, and it can be stacked up to four storeys high. Due to its flexibility, it can be placed at will with a forklift, and the warehouse can be used in one area without regard to the first-in-first-out of goods.

Four. Electric mobile racking is divided into two kinds of railroad racking and random racking, access to goods can be 100% random, the diversity of goods batch and variety of sizes both compatible. There are about 16 cargo spaces, including electric rail racks of the track laying needs to be carried out twice to the ground construction, the overall installation time is longer, the seismic capacity is also higher, the cost of the unit of cargo space is 750-1000 yuan, excluding the cost of the ground construction, the overall carrying capacity of the trackless electric rail racks is somewhat weak, relying on the magnetic guide rods to do the guiding. Electric shelves are used in cold storage, the electric control box, bearings, wires, etc. must be specially treated;.

5. The access mode of shuttle rack is the same as that of drive-in rack, the middle area can be FIFO or FIFO, and the wall can be FIFO. It is suitable for accessing goods with few varieties and large quantities, and the depth of the cargo compartment can be up to 30 compartments. Shuttle set of light, machine, electricity in one. Whether the quality of its own products is excellent is very important to the customer's future logistics work. Whether the electronic components in the car have enough anti-interference ability to the light, noise, temperature and vibration generated by the reciprocating motion of the warehouse is an important factor in the price of the shuttle car.

Different owners should be based on the student's own funds, cargo characteristics, logistics development state information to analyze a variety of racking trade-offs there is no one necessary to blindly follow the trend.

In the choice of shelf refrigeration materials, although Q235 is also feasible, but the choice of small stress, good toughness of the material, as close as possible to the theoretical performance of Q235. In the shelf surface treatment, the need to use double protection, anti-rust layer and anti-freeze layer, the industry is currently providing this special plastic powder, as long as the quality on line.

How does a shuttle racking system work properly in a cold storage environment? (Pictured above is a Hercules shuttle in a factory trial run.)

In a low temperature cold storage environment, the design of the shuttle racking system will be improved from the design of the traditional shuttle racking system. Adopting shuttle racking system in cold storage and other warehouses, or cooperating with automatic stacker cranes to realize automatic three-dimensional storage, can greatly improve the utilization rate of warehouse space.

Low-temperature cold storage environment of the ferry design should be considered, including: the body, axles and other steel structural components of the material selection and structural design avoidance, as well as low-temperature environment of the electrical components and their components of the performance of the impact and selection of the considerations, in order to reduce the design of low-temperature environment of the hidden safety hazards, improve the low-temperature environment of the ferry operation of the stability and reliability. Due to the fact that it involves the selection of various materials and electronic components, the handling of processing technology, the installation and commissioning of products as well as the lack of product standards for low-temperature use and the support of test data, the analysis of the reliability of the operation of shuttle buses under low temperatures appears to be very urgent and difficult. It is necessary to continuously analyze the operation test data and customer application experience report under low temperature environment, and explore the improvement of design theory and standard comparability test and its standard.

Those who do not have obscure and difficult to understand the principle and design to explain, I here we will not say.

In conclusion, China's cold chain logistics industry has been developing well, which inevitably has some problems. With the rapid development of cold chain logistics of agricultural products in China, the state must formulate and implement scientific and effective macro policies as soon as possible. The requirements of cold chain logistics are relatively high, and the corresponding management and capital investment are also larger than that of ordinary room temperature logistics. Emphasizing "cold", the management certainly emphasizes "cold".
