The dose of the tablet press is to be strictly controlled
The working principle of the tablet press is still one-way tablet compression based on manual compression molding, that is, the lower punch is fixed during tablet compression, and only the upper punch moves to pressurize. Due to the inconsistency of the upper and lower forces in this tablet pressing method, the density inside the tablet is not uniform, and problems such as splits are prone to occur. This kind of tablet press presses up and down uniformly at the same time, so that the air in the drug particles has enough time to escape the die hole, which improves the uniformity of the tablet density and reduces the phenomenon of splitting. It is no longer simply limited to pressing Chinese and Western medicine tablets, but can also widely press health food, veterinary drug tablets, and chemical tablets. &
In clean area management and quality control, laminar flow interference testing has received much attention, and whether it is only applicable to Class A laminar flow remains to be considered.
