Embodiment 1
[0038] The preparation method of the pharmaceutical excipient of microcrystalline cellulose and guar gum compound chewable tablet comprises the following steps:
[0039] Add 500 kg of medical deionized water, then add 12.5 kg of pharmaceutical grade guar gum dry product, use SWFS-400 type high-speed disperser to stir, and the stirring rate is 100 rpm;
[0040] After guar gum dissolves completely, add 100 kilograms of microcrystalline cellulose (water content is 45%, polymerization degree is less than 350, and pH is 6.0); Improve stirring to 450 rpm, continue to stir for 25 minutes;
[0041] Then the resulting mixture slurry is dried with a spray drying tower, and the air inlet temperature is set to 200°C, the outlet air temperature is 130°C, the atomization speed is 50HZ, the feed flow rate is 0.5 cubic meters per hour, and the negative pressure is 300 Pa , dried, and the obtained solid powder was sieved to have a particle size d50 of 200 microns. The particle size was detecte...
