Traditional angelica drying processes use processes such as shade drying, sun drying, and oven drying for dehydration. This traditional drying method processes the entire angelica product in batches during the drying process. This will result in different sizes of angelica having different dehydration speeds. In order to ensure that all angelica in the batch meet the drying moisture content standard, all angelica will be dried according to the maximum dehydration time.
