Investigation of Flow Field in Cold Store of Cold Storage Chain

The development of Chinese cold storage chain logistics is relatively backward which affects the food industry. Cold store is the key part of cold storage chain. The flow field is an important technological parameter in cold store. A three dimensional mathematical model was established to study the flow of field distribution inside a cold store. The results are testified by experiments. Some rules are discovered. It is revealed that the optimal inlet air velocity is in the range of 3–5m/s for a cold store. The results will provide an important help on the technical development of the cold storage chain logistics in China.
