Benefits Of Rotary Tablet Press Machines

By Harriett Crosby


In the pharmaceutical industry, there are several types of products that are released to the market. Some are in the form of syrup, liquid injections, topically applied creams and ingestible tablets. In the production of tablets, this machine is required to produce the desired shapes and sizes. Currently, manufacturers use the more advanced Rotary Tablet Press machines. Those with little production needs still use the single-punch one which is slower.

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 powdered medicine is first compressed under very high pressure by the hardened steel plates in the press machine. The machine is programmed to produce precisely sized and shaped tablets with measured weights for dosage requirements. This process is also applied in the production of cosmetic products and other cleaning products for the market.

The process basically consists of flow, compression and ejection of the final product. Flow involves passing the powdered material into the press. It is then compressed to compact it into the desired sizes and shapes. The final stage is ejection of the tablet for packaging and release to the market.

Upper and lower punches together with a punching dye concertedly work to bring out the specified weight, size and shape of drug. It is filled into the dye as required then after closing the upper and lower punches; a pressurized roller applies pressure to compress the powder. The two punches with dye the releases the tablet hence ejection.

The press machines have several benefits. They have a good cost ratio of owning one. Their cleaning is very simple and operating them is very easy resulting in high yields. Changing the format is very fast and the parts are easy to assemble hence the short cleaning time.

The in-built dust extraction mechanism continually keeps the head section free of dust as it operates. The vacuum regulation contributes greatly in the smooth functioning of the machine. The accuracy of the machine is impressive even under heat and static stress. It works safely and takes long before it requires maintenance.

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.
