Understanding 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.

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.

By use of hardened steel plates, the powder id highly compressed. This calls for programming the entire process so as to produce precisely sized tabled with the desired weight so as not to overdose or under dose the consumers. The machines are also used in the manufacture of cleaning products and some cosmetics other than pharmaceuticals.

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.

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.

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.

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.
