With the rapid development of e-commerce, online shopping has become an indispensable part of people's lives. Every aspect of clothing, food, housing, and transportation starts to depend on various B2B websites. Almost everything can be bought, even frozen foods such as seafood, dairy products, and fruits and vegetables are easily corrupted. In order to better refrigerate this type of fresh-keeping product, a refrigerated car came into being. Nowadays, the types of refrigerated trucks can be varied, but the total can be classified roughly according to the type of vehicle and according to the cooling method of refrigeration equipment. According to the model, it is small, medium, and large. According to the refrigeration method of the refrigeration device, it is classified into a mechanical refrigerated truck, a frozen-plate refrigerated automobile, a liquid nitrogen refrigerated automobile, a dry ice refrigerated truck, and the like. Each refrigerated truck has different advantages and disadvantages that can be selected according to their own needs. 1, mechanical refrigerated truck: the car is equipped with compression refrigeration unit, the car temperature to achieve automatic control, it is suitable for short, medium, long-distance or special refrigerated cargo transportation. The car has good heat insulation, reduces the temperature inside the outside car, and the refrigeration device occupies less space, is light in weight, safe and reliable, and is not easy to fail. 2, liquid nitrogen refrigerated truck: the device is simple, the initial investment is small, the cooling rate is fast, can better maintain the quality of food, no noise, compared with the mechanical refrigeration device, the weight is greatly reduced. Disadvantages: High liquid nitrogen costs, liquid nitrogen supply difficulties during transportation, long-distance transport must be equipped with large liquid nitrogen containers, reducing the effective load. 3, Refrigerated plate refrigerator: It is the use of frozen plates with a certain cooling capacity for cooling. Refrigerated plate refrigerated truck has the characteristics of stable temperature inside the car, no noise during refrigeration, less malfunction, simple structure and low investment cost. However, its cooling time is limited and it is only applicable to medium and short-distance road transport. The frozen plates of refrigerated cars are often used to transport various fresh foods such as precious fruits and fresh seafood. 4, dry ice refrigerator: equipment is simple, low investment costs, low failure rate, maintenance costs, no noise. Disadvantages: The temperature in the compartment is not uniform enough, the cooling rate is slow, the time is long, and the cost of dry ice is high. In recent years, the refrigerated truck market has become a new hot spot for consumers. Some manufacturers have discovered this business opportunity and started to produce refrigerated trucks. Recommend several famous brands such as Dongfeng, Jianghuai, Jiangling, Liberation, Isuzu and others. Here is an example of the Jiangling brand refrigerated truck. The reason why it has become the leader in refrigerated trucks is that it has unique advantages and high-quality services. It is not only cheap but also cost-effective. Streamlined design - aerodynamic principles, streamline modeling, a sense of speed, saving energy and effort. FRP rigid box board - with glass fiber reinforced composite panels for the panel, the whole assembly, no cold bridge design, the body is persevering. Classic chassis structure - a composite structure made of a variety of materials pressed together to improve the chassis cold air convection and impact strength and waterproof performance. Import refrigeration unit - the first dual air conditioning system. These personalized transformations have made Jiangling a brand more powerful and a leader in the industry. It is really worthwhile. Whether it is hot summer or cold winter, with a refrigerated truck, no longer afraid to eat less fresh things. The seller must purchase a vehicle that meets the same function according to his own needs. Hope that the above information can help you.
Spray Dryer Equipment:
The spray dryer is widely used in chemical, food, pharmaceutical industries. It can convert the liquid, suspension, emulsion into powder product. It can keep the product color, flavor and quality. The heat source can be electric, steam, natural gas, coal and diesel.

The spray drying is the widest used technology in the liquid shaping technology and in the drying industry. It is most suitable for producing powder, particle, or block solid products from materials of solution, emulsion, soliquid and pumpable paste states. Therefore, when the particle size and distribution of the final products, their residual water contents, the stocking density and the particle shape meet the precision standards, the spray drying is one of the most desired technologies.
Spray dryer features
1, High speed of drying. After the spraying of he material liquid, the surface area of the material will be increased greatly. In the hot-air flow, 95%-98% of water can be evaporated at a moment. The time of completing the drying needs only several seconds.
2, It is especially suitable for drying the heat sensitive materials. It`s final products own the good uniformity, mobility, dissolving capacity. And the final products are high in purity and good in quality.
3, The production procedure is simple and the operational control is easy. The liquid with the moisture contents 40-60%(for special materials, the contents may reach 90%) can be dried into power or particle products once a time. After the drying, there is no need for smashing of sorting, so as to reduce the operation procedures in the production and enhance the purity. The product particle diameter, looseness and water contents can be adjusted through changing the operation condition in a certain scope.
