Mixing pharmaceutical materials machines

Example 2 In a Pet Tabs (pet vitamin tablets) production, the pharmaceutical manufacturer is using milling and micronizing machines to pulverize raw materials into fine particles. These finished particles are combined and processed further in mixing machines. The mixed ingredients are then pressed into tablets, dried, and sealed in packages. A normally distributed quality characteristic, moisture content, is monitored. Samples of n = 4 tablets are taken from the manufacturing process every hour. The data after 25 samples have been collected are shown in Table 5. 

As mentioned before, these requirements can be met only if the feed has been granulated after mixing. Today, most of the granulation methods used in the pharmaceutical industry are carried out to produce materials suitable for feeding tabletting machines.
