[0024] The preparation method of the present invention includes: extracting traditional Chinese medicine, drying the extract into extract, selecting excipients, mixing extract and excipients, spray granulation, and compressing tablets. Among them, the temperature of the material after the step of mixing the extract and the excipient is 60-80°C; in the spray granulation step, the atomization pressure I is 0.05-0.1MPa, the atomization pressure II is 0.05-1Mpa, and the spray speed It is 10-20r / min.
[0025] The reason for choosing the above material temperature: when the material temperature is lower than 60℃, the extract is sprayed with excipients to form particles and the drying is not timely enough to cause material adhesion and wall hanging, and the atomization pressure and spray speed cannot be adjusted greatly. , Which directly affects the granulation of the particles, and the particle diameters obtained are smaller. When the temperature of the material is about 60-80℃, the m...

[0036] Example 1 Hedan preparation extract tablet
[0037] (1) Extract Chinese medicine:
[0038] Hedan extract was prepared and extracted according to the method of loading Dan tablets in the pharmacopoeia. The Chinese medicine prescription is a prescription for Hedan tablets, including lotus leaf, hawthorn, salvia, senna, and psoralen.
[0039] (2) Dry extract into extract:
[0040] The extract is concentrated to an extract with a relative density of 1.22-1.26 (measured at 80°C), and the water content of the extract is 42.3%.
[0041] (3) Select excipients:
[0042] The dextrin, starch, and disintegrant are taken to form excipients in a mass ratio of 2.5:5:1.5, and the disintegrant is preferably sodium carboxymethyl starch.
[0043] (4) Mixed extract and excipients:
[0044] Use 75% ethanol to disinfect and dry the inner wall of the equipment mainframe. After the equipment is dry, add 0.9 kg of excipients into the multifunctional granulator, push into the host, and pour 2.25 kg of extr...

[0049] Example 2 Preparation of Jiangzhiling Tablets
[0050] (1) Extract Chinese medicine:
[0051] Take 2.22 kg of Polygonum multiflorum, 2.22 kg of wolfberry, 2.96 kg of Polygonatum, 1.48 kg of hawthorn, and 0.44 kg of cassia seed, and extract the extract according to the preparation method of Jiangzhiling tablets recorded in the 2010 Chinese Pharmacopoeia.
[0052] (2) Dry extract into extract:
[0053] The extract is concentrated to the extract for later use, and the water content of the extract is 45%.
[0054] (3) Select excipients:
[0055] Dextrin, starch, and disintegrant are taken to form excipients in a mass ratio of 2:10:1, wherein the disintegrant is preferably low-substituted hydroxypropyl cellulose.
[0056] (4) Mixed extract and excipients:
[0057] Use 75% ethanol to disinfect and dry the inner wall of the equipment mainframe. After the equipment is dry, add 1.77kg of excipients into the multifunctional granulator, push it into the host, and pour 2.66kg of extract into t...
