Understanding Rotary Tablet Press Machines

By Harriett Crosby


May do not know this, but in the manufacture of pharmaceuticals a press machine is required in the final stages of the process. Some firms use single phase machines while some use the more advanced Rotary Tablet Press machines. These are used to create the tablet medicines that are commonly swallowed. As time progresses so does technology in all the fields of science.

Before the invention of the press machines, the granulated medicine was placed on a conveyor belt and compressed in foils by hand. The production costs using this method were very high hence the high cost of medicine. In addition, the exposure of the drugs to human contamination was high. The machines in use now have very limited or no human contact hence lowered chances of bacterial contamination.

The medicinal powder is compressed under very high pressure between hardened steel plates. This process is programmed to produce solid tablets of specific weights so as to conform to dosage requirements of patients. Other than their use in pharmaceuticals manufacturing, these press machines are also used in cosmetics an even cleaning products manufacture.

These machines basically involve flow, compression and ejection of completed product. In the flow stage, the powdered medicine is directed into the machine where it fills the punches and is compressed into the desired shapes. After this it is then ejected then collected for packaging and sold to the market.

In the second stage, an upper and lower punch together with the chosen dye prepares the powder then it is subjected to the rollers with high pressure. The punches then open to release the tablet which is then ejected. This whole process is repeated again and again as may be required.

These press machines comes with several benefits. Owning one has great cost benefit ratio. Cleaning one is a simple process and is easy to operate hence very high yields. For one to change the format no much skill is required and the parts are easy to reassemble therefore the short cleaning time.

They come with in-built dust extraction making the head section dust free. They have vacuum regulation and if one desire, a window display for large format indication. They come with very good accuracy even under stress like thermal and static. Their working safety is known to be very good and comes with long maintenance intervals.

The available types of press machines are the single-punch and Rotary Tablet Press machines. The high performer is the second one with performance suitable mass production. Its speed of tablet production is high hence cost saving to the manufacturer of drugs. It can hold many punches thereby saving time and overhead costs when producing tablets of any kind. It allows for custom designing of the dyes so as to press any desired shape and size of tablet. The process has automated monitoring therefore it can handle high speed pressing producing more as compared to human monitoring that is much slower. Buy a machine that has a closed system that will keep the components separate to avoid cross-contamination that is bad in the case of pharmaceuticals. Consider the amount of tablets it can produce over a given time frame.
