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.

In the former days, manufacturers of pharmaceutical products had to place the material on conveyor belts where they were then compressed and packaged by the use of foils. A process that was prone to biological contaminants like bacterial transfer from the humans handling the drugs. The process was also very expensive in terms of production costs to the manufacturers. Currently the processes are automated requiring very limited human contact.

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.

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.

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.

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.

There are two types of press machines, the single-punch and the Rotary Tablet Press machines. The second one is preferable since it has many cost saving benefits to the manufacturer. It can hold several punches meaning more output per specific timeframe. The dyes and punches for this machine are designed to custom for the production requirements. Monitoring the process is automated so the mass production is a fact while ensuring quality of the products. Consider buying a closed system so as to prevent cross-contamination with other products especially when working with drugs. Work with the high performance machines and you will never regret it.
