Tablet multiple tools

The simplest type of rotary machines is single sided (one feed location) one tablet is produced from each station (die) per revolution. Therefore, the output of rotary machines depends on the number of stations in the turret (table) and the speed of the turret. It is usually in the region of 300-800 tablets per minute. A further increase in output is possible by using a double-sided machine. In this case the stations are filled twice on opposite sides of the rotating table two compressions are carried out in each die per revolution of the turret. Outputs of up to 3000 tablets per minute can be obtained from the double-sided machine. Still further capacity increases can be obtained by dual or multiple tooling (two or more dies) per station. [Pg.229]

Despite the diligent use of predictive studies, compaction simulation, pilot scale work, the state of the art of tablet scale-up still provide opportunities for problems to arise. The issues typically encountered are those that have multiple factors involved, and are difficult to predict and simulate at smaller scale. Of these problems, tablet mixture flow, including weight uniformity and segregation, and sticking and picking of the tablet mixture to the tools and tablet specks, are common occurrences. [Pg.392]

The basic unit of any tablet press is tooling consisting of two punches and a die, called a station. The upper and lower punches come together in the die that contains the tablet formulation. Principally, two different types of machines are used, the eccentric and the rotary press. The eccentric press produces about 50-130 tablets per minute. The rotary press has a multiplicity of stations arranged on a rotating table with the dies. A few or many thousands of tablets can be produced per minute. There are numerous models of presses, manufactured by a number of companies, ranging in size, speed, and capacity. [Pg.978]
