More About 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.

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.

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.

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.

Many types of these machines exists, these includes single-punch press and Rotary Tablet Press machines. The rotary press offer very high speeds and can hold many punches for mass production and time saving benefits. Dyes and punches are designed specifically for every job meaning the shapes and sizes are unique to a customer's needs. The process monitoring is automated and the components of these machines are of very high quality. When buying one for pharmaceutical use, consider choosing one with a closed system so as to avoid cross-contamination. The amount of tablets it can produce in a specified time should also be considered in addition to its ability to change the charging and compression modules easily. For the best in production, always go for the high performance machines and you will not be disappointed.
