[0032] First, the first stage of drying is hot air drying at a temperature of 60°C for 1 hour;

[0033] Then adjust the temperature to 75℃ and carry out the second stage of drying, hot air drying for 40min;

[0034] Then the product was subjected to microwave drying treatment and the third drying step was performed, and the drying time was 10 min;

[0035] Finally, hot air drying is carried out at 60°C for 55 minutes to complete the fourth drying process.

[0036] As a further technical solution: the power of the microwave drying process is 500W.

[0037] As a further technical solution: the dried Pueraria slices are crushed as follows:

[0038] It is divided into three levels of crushing, and each level of crushing is screened;

[0039] The aperture of the first-stage filter screen is 1.25 mm;

[0040] The aperture of the secondary filter screen is 0.5 mm;

[0041] The space of the third-stage filter screen is 0.05mm.
