Problems solved by technology

However, after slicing, the epidermis is destroyed, and the contact surface area between the internal tissue and the external space increases, which instead increases the loss, damage and deterioration of the active ingredients in Danshen during processing.

[0006] In addition, vacuum drying, infrared drying, microwave drying and other methods are also used in the prior art. When the whole ginseng is dried, the disadvantages of uneven water content inside and outside the dry product and loss of active ingredients still exist, and the drying effect is still not ideal. poor overall effect

Moreover, the processing process is complicated, the equipment configuration requirements and cost are high, and it is not suitable for popularization and application.
