Embodiment 1
[0040] Feeding amount is shown in Table 1 (unit: kg)
[0041]
[0042] Prepare penicillin V potassium tablets according to the following preparation method from prescription 1 to prescription 6
[0043] Preparation Process:
[0044] (1) Preparation of adhesive: according to the weight ratio of povidone K30 and purified water is 11:28, add the povidone K30 of prescription quantity into purified water, stir while adding, place until it is completely dissolved, Pass through 120 mesh sieve;
[0045] (2) Granulation: Add penicillin V potassium into the tank mixer, mix for 2 minutes, add the adhesive, and stir for 3 minutes to make a soft material that can be held in a ball and disperse when lightly pressed. Granulate in a swinging granulator with a 22-mesh nylon screen to obtain wet granules;
[0046] (3) Drying: Pour the wet granules into a boiling dryer for drying at a temperature of 45°C for 35 minutes, and when the moisture content of the granules is controlled below 2.0%...
