Air circulation

Air circulation in the cold storage of Chinese herbal medicines is also one of the factors to be considered in the cooling process. Good air circulation can evenly distribute the temperature and avoid temperature differences inside the cold storage. In addition, good air circulation can also reduce humidity build-up and prevent the growth of mould and bacteria.

Packaging and Storage
