How Does A Rotary Tablet Press Produce High Quality Tablets(part 1)

The tablet press, for nowadays, are widely applied in many fields, no matter for the single punch tablet press or the rotary tablet making machine. People are more likely to accept daily things in the form of tablet, like the nutraceutical tablets, candies, milk tablets, detergents, salt block, etc. Therefore, the tablet press machine appeared to meet this demand. Based on the size, thickness, and hardness of the tablets, tablet press selection is a quite professional work. To make most use of machine and for financial consideration, the single punch tablet press should be applied to small batch production or lab use, while the rotary tablet press including the medium-high speed and high speed press are more suitable to be used for mass production.

Whatever fields the tablet press devote in, quality control will always be the most concerned. Compared with the manual pill press and the single punch tablet presser, the rotary tablet press is a mature machine to make high quality tablets, on which professional design and accurate components are equipped. So what makes the rotary tablet press stand out? And how does it secure tablet quality? As summarized, there are 5 possible reasons.


Rotary TabletI Feeding System

On a rotary tablet press, the feeding system consists of hopper and feeder. The hopper is erectly installed, from where the granules pour in and flow down along its inwall. Excellent fluidity guarantees constant weight and also effectively improve the quality and appearance f tablets. The clearance between feeder and surface of turret can be adjusted based on the size of granules as well as its fluidity, so as to reach an optimized consequence. However, the force feeder is optional on the machine.


II Guide Rails

The guide rails are composed of upper guide rail and lower guide rail, which forms the cylindrical cam and planar cam. The guide rails are equipped above the rotary table where the dies are set in, and the punches including the upper punches and lower punches run up and down along the rail so as to finish the compression course. When the upper punch goes down towards the middle die, the lower punch also goes up. Subjected the pressure from both sides, the granules are compressed in the middle die.
