Different types of products have different temperature and humidity requirements during transportation, some have higher temperature requirements, some have higher humidity requirements, and some even require specific temperature and humidity environments. For example, medicines, food, cosmetics, etc. are all perishables and need to be stored at a suitable temperature and humidity, otherwise they are easy to deteriorate, rot, and lose their efficacy or taste. For another example, cultural relics and antiques such as rare animal specimens and works of art need to be stored under relatively stable temperature and humidity to prevent deterioration and corrosion.
The influence of temperature and humidity on transported products
Temperature and humidity have different effects on different types of products, let's take a look at them separately.
1. medicine
Medicines have very high requirements on temperature and humidity, because they are often highly sensitive chemical substances, and their efficacy and safety are affected by temperature and humidity. For example, some biologics and protein drugs need to be transported and stored under low temperature conditions, otherwise they will lose their activity. In addition, some chemical agents are easy to decompose or produce harmful substances under high temperature conditions, and easy to get damp or agglomerate under humid conditions. Therefore, in the process of transportation, according to different types of medicines, choose the appropriate transportation method, thermal insulation bag or refrigerator. And through the temperature and humidity monitoring system to monitor and control the transportation process of medicines in real time.
2. Seafood
The freshness period of seafood is very short, and measures need to be taken during transportation to ensure its freshness. Temperature has a great influence on seafood, because if the storage temperature is too high, bacteria in seafood will multiply rapidly, causing seafood to deteriorate and produce peculiar smell. Therefore, when we transport seafood, we need to put it in a fresh-keeping bag, extract the air, and then seal the bag to reduce air contact. In addition, it is also necessary to control the transportation temperature during transportation, such as transporting seafood in ice and keeping it at a low temperature, so as to reduce the spoilage rate and loss of seafood.
3. Fruits and vegetables
Fruits and vegetables also have strict requirements on temperature and humidity. If it is stored in a high temperature and high humidity environment, it will accelerate the ripening and decay of the fruit. Storage in a low temperature, low humidity environment will cause the fruit to lose moisture and become dry and brittle. Therefore, plastic wrap or fresh-keeping bags can be used to control the temperature and humidity of fruits and vegetables during transportation. In addition, for some ripe fruits, such as mango, banana, etc., we need to control the transportation time and speed.
How to monitor the temperature and humidity during transportation
In order to ensure that the temperature and humidity during transportation meet the product requirements, we need to use temperature and humidity recording instruments to monitor the temperature during transportation. Common temperature and humidity recording instruments include usb temperature and humidity data logger, GPRS temperature and humidity data logger, etc. These instruments can record the temperature and humidity data during transportation in real time, and through data analysis and comparison, abnormal situations can be detected and dealt with in time.
In addition, we also need to properly package and label the products before transportation to ensure that the products will not be affected by the external environment during transportation. For example, when transporting medicines, you can use thermal insulation bags or refrigerators to maintain a suitable temperature; when transporting seafood, you can put seafood in sealed fresh-keeping bags, and mark the shelf life and temperature of the product on the outer packaging, so that Monitors monitor and control.
In addition to monitoring temperature and humidity during transportation, we also need to monitor temperature and humidity after the goods arrive at their destination. If there is an abnormal situation during transportation, such as a decrease in drug efficacy due to high storage temperature of the drug, or a shortened shelf life of seafood, it is necessary to take timely measures to deal with it.
