More About 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 earlier days, tablets were placed on conveyor belts where they were compressed and packed by the use of foils. This resulted in high production costs and great material wastage. Additionally, the use of human hands to do the work exposed the drugs to transfer of infections like bacteria. The current methods are majorly automated and require minimal human contact if at all.

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.

Two punches combine in action with a punching dye to create the desired shape and size of tablet. The powder fills the specific dyes which are then closed then a high pressure roller comes in to compress the material. The dyes then give way to release the tablet as a final product.

There are many benefits of using the machine. Their cost ratio of ownership is very good. Cleaning them is quite simple and they come with easy operation procedures hence high yields. One can change the format fast and easily assemble the parts resulting in shortened cleaning time.

Their in-built dust extraction works to make the head section dust free all the time when working. The vacuum regulation and optional large format window display makes the press a wonderful machine for tablet production. They are accurate and maintain this even under thermal and static stress. The machines will work safely and the maintenance interval is extended.

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.
