Preparation process of pummelo peel tablets

The invention provides a preparation process of exocarpium tablets, and belongs to the technical field of preparation of exocarpium tablets. The preparation process comprises the following steps: preparing pummelo peel beads; preparing pummelo peel slices containing probiotics; preparing a finished product of the pummelo peel tablet. The low-temperature and low-pressure technology is adopted to moisten the dried young fruits of the exocarpium, loss of heat-sensitive effective components can be reduced through low-temperature treatment, it is guaranteed that active substances such as flavonoid compounds and volatile oil in the exocarpium are not degraded or invalid due to high temperature, and the low-pressure environment is beneficial for water to rapidly permeate into medicinal material tissues; the pummelo peel can reach an ideal softening state within a short time, the moistening efficiency and the production speed are improved, the damage to the structure of the pummelo peel caused by too fast or excessiv
