In the cold chain transportation of drugs, it is necessary to stack the goods on double boards to avoid obstructing the active circulation of air in the goods; The method of product quality during cold chain transportation introduced in cold chain transportation is usually used for aluminum iron floor ventilation; But there are also some refrigerator cars that do not have aluminum rails, and the use of flat anti slip flooring also has this effect. Below is a detailed introduction on how to ensure the quality of products during the cold chain transportation of drugs?
1. Ensure circulation of cold air
Due to the defrosting plan of the refrigeration unit for refrigerated transportation, the air can freeze. When the product and the outlet are too close to the evaporator coil, rapid frost (or ice) can affect the product, and the air induction switch can quickly defrost. When the temperature of the coil returns to the standard temperature, defrosting is immediately completed, resulting in an operating cycle that leads to a decrease in the loading body temperature. Everyone's intuitive feeling is that defrosting equipment is always frequently replaced, which is actually not the case. Doing so will only add refrigeration and transportation cost standards. It is necessary to pay attention to the use of double-sided boards during loading and unloading to ensure circulation of cold air on the surface.
2. Keep the carriage clean
It is necessary to keep the interior of refrigerated transportation clean and free from packaging paper and ground paper scraps, as debris can prevent air circulation. When using a refrigerated vehicle, it should be kept clean. Due to the function of the evaporator fan, air circulation can allow many impurities to enter the evaporator coil, thereby affecting the refrigeration effect of the refrigeration equipment. The decrease in heat transfer rate of the coil due to impurities surrounding it. So after using refrigerated trucks for a few years, they may feel that the refrigeration effect is not as good as the beginning, except for their own reasons, it only needs to be cleaned due to the coil being too dirty.
In summary, to ensure the quality of products during refrigerated transportation, it is first necessary to ensure the circulation of cold air, and then to keep the carriages clean. In order to ensure the cleanliness of the transportation floor, the key is to ensure the normal operation of the refrigeration equipment for refrigerated transportation. Therefore, it is necessary to minimize the time when opening the door and use window cloth as much as possible. To ensure that goods with different temperatures are transported in the same vehicle space, it is strictly prohibited. The correct operation and use of refrigerated trucks are key to ensuring the quality of temperature controlled goods and ensuring the normal operation of refrigeration equipment.
