The microwave drying of Weikang Capsule is dry in the hot air circulation drying room, the drying period is long, and the quality of the product after drying is not high.
After purchasing vacuum microwave equipment in our hospital, we want to improve the drying process by vacuum microwave method. However, due to the excessive amount of jaundice in the prescription, the dried extract contains more saponins, which makes it easy to foam during vacuum microwave drying. As a result, the drying operation cannot be performed or even the overflow of the extract is lost.
