Road refrigerated trucks can be divided into three levels of D, E and F according to the matching requirements of the used car body and the mechanical refrigeration unit. The fundamental difference is the adjustable temperature. According to the difference in the adjustable temperature, the transportation products of refrigerated transport vehicles of type F can generally be divided into several major categories. The first type of frozen foods are frozen meats, aquatic products, quick-frozen foods, and some foods that are not easily preserved. The storage temperature required for these foods is generally below -18 degrees, and can be stored for a long time in such environments. Similar to this type of item, it is not necessary to strictly control the temperature during transportation, and it is only necessary to maintain the temperature at -18 degrees. The second category refrigerated food, cold meat, aquatic products, poultry eggs and so on. Such foods only need to ensure that the food is not frozen, the temperature is low and good, you can also use F refrigerated trucks to participate in transport. The third category is fruits and vegetables. The requirements for transportation of such foods are relatively high and the temperature requirements are constant. At the same time, it is necessary to reduce or organize the respiration of vegetables through cold, to prevent the decay of vegetables. At the same time, we must also pay attention to the refrigeration system of refrigerated trucks. For example, ice, salt, ice, salt, and ice are liable to dissolve and erode the compartments, making the properties of the cargo wet. Ice cooling system. Dry ice is a commonly used physical cooling substance, which occupies a small space, which can reduce the burden on the vehicle body and reduce fuel consumption. Dry ice cooling slows down and prevents oxidation reactions and prevents deterioration of items. It is mostly used for short-distance transportation of fresh fruits and vegetables. Although this type of product is not particularly stringent for low temperature requirements, F-type refrigerated trucks are occasionally used. The F-type refrigerated trucks have a wide range of applications, good heat insulation and good refrigerating performance. They quickly win a large sales market for such refrigerated trucks. Due to better refrigeration, the actual space available for this type of vehicle has traditionally been smaller, but with the continuous improvement of core technologies for manufacturing and refrigeration, the space available for Type F refrigerators is constantly expanding, with traditional bread-type refrigerated trucks. The main shift to semi-hanging refrigerators. The domestic introduction of new technologies has continued, and this category of refrigerated trucks has also been monopolized by foreign countries to autonomous production, which has greatly reduced the price of F-type refrigerated trucks. China's current production technology is mature, such as Jianghuai and Tibetan brands have a good response. The intrinsic advantages of F-type refrigerated trucks make them applicable to a wide range of applications. Besides the basic functions of A, B, C, and D refrigerated trucks, they have good insulation effects. Stronger features lead to higher prices, and it will also lead the way in the development of refrigerated trucks.
Perilla seed powder has the functions and effects of clearing away heat and dispersing cold, antibacterial and antiviral. Perilla seed powder is rich in nutritional value and is a plant that can be used both as medicine and food. After consumption, it can supplement the nutritional needs of the body. Perilla seed powder has a certain effect on improving symptoms caused by colds and symptoms such as edema and numbness of the lower limbs caused by dampness. In addition, perilla seed powder can also improve memory, enhance brain development and brain nerve function.
