Embodiment 1
[0018] Weigh 0.255-0.260 g of gardenia formula granule dry cream powder, put it into the tableting mold of an infrared tablet machine, press 15 MPa, pressurize for 15-20 seconds, hold for 5 seconds, and take out the tablet core.
[0019] Usually, pharmaceutical production uses a rotary tablet press to prepare tablets, but the actual production maximum pressure of the rotary tablet press is usually below 3MPa, and high-pressure tablet compression cannot be performed. The production of traditional Chinese medicine formula granules usually uses a dry granulator, and the actual maximum production pressure of the roller is above 20MPa, so the rotary tablet press cannot simulate the preparation of the tablet samples of the dry granulator. The infrared tablet machine is an accessory of the infrared spectrometer, not a commonly used tablet pressing equipment. The actual maximum pressure for preparing tablet cores exceeds 25MPa, and the effective pressure range is basically the same as ...
Embodiment 2
[0022] Weigh 0.255-0.260g dry paste powder of drynaria formula granules, put it into the tabletting mold of an infrared tablet machine, press 15MPa, pressurize for 15-20 seconds, hold for 5 seconds, take out the core, and use the tablet The hardness tester measures the core hardness, and the result is 117N. It is predicted that the moldability of drynaria dry paste powder of this batch belongs to a good range. The parameters for determining the dry granulation molding are pressure: 10-15MPa, and the production speed of the equipment is set at a medium speed (roller speed 12-15r / min).
Embodiment 3
[0024] Weigh 0.255-0.260g of rhubarb formula granule dry cream powder, put it into the tableting mold of an infrared tablet machine, press 15MPa, increase the pressure for 15-20 seconds, hold the pressure for 5 seconds, take out the tablet core, and test it with a tablet hardness tester The core hardness was measured and found to be 165N. It is predicted that the moldability of this batch of rhubarb dry paste powder belongs to a very good range. The parameters for determining the dry granulation molding are pressure: 5-10MPa, and the production speed of the equipment is set at high speed (roller speed 18-20r / min).
