Application of Rotary Tablet Press Machine in Production

Rotary tablet press, also known as a multi-station tablet press, is an advanced tablet compression machine designed to address the limitations of traditional single-punch tablet presses, particularly issues such as uneven tablet density, friability, and inefficiency. The machine compresses tablets simultaneously from both the top and bottom, expelling the air from the die cavity to ensure uniform tablet density. Additionally, rotary tablet presses offer advantages including low machine vibration, reduced noise, energy efficiency, high productivity, and precise tablet weight control.

The Prospect of Tablet Press

According to the report “Tablet Processing and Packaging Equipment Market – Global Opportunity Analysis and Industry Forecast (2017-2022)”, the global tablet processing and packaging equipment market is expected to grow at a compound annual growth rate (CAGR) of 8.8%, reaching $5.2688 billion by 2022. This growth is driven by factors such as an aging population, rising prevalence of chronic and infectious diseases, and advancements in pharmaceutical technology.

Faced with intensifying competition and the growing threat of antibiotic resistance, pharmaceutical companies are under pressure to rapidly develop new drugs. Additionally, the global demand for medications continues to rise due to demographic shifts and increasing rates of chronic diseases, further compelling pharmaceutical firms to enhance production output.

This has led to a surge in demand for pharmaceutical processing equipment, as it streamlines various stages of tablet production and addresses labor-intensive challenges inherent in traditional methods, which contribute to extended manufacturing times and higher production costs. Consequently, the adoption of automated equipment across different stages of tablet manufacturing is increasing to significantly reduce errors and manual operations, while improving the efficiency of tablet processing and manufacturing.

The Working Process of the Tablet Press

The working process of the tablet press can be divided into the following steps:

Working process of a tablet press machine.png

  1. The punch position of the down punch (its working position is upward) extends from the lower end of the middle mold hole into the middle mold hole to seal the bottom of the middle mold hole
  2. Use a feeder to fill the middle mold hole with medicine
  3. The punch part of the upper punch (its working position facing downwards) falls from the upper end of the middle die hole into the middle die hole, and goes down a certain stroke to compress the powder into tablets
  4. The upper punch lifts out the hole. The downward punching and rising will push the tablets out of the middle die hole to complete a tablet pressing process
  5. The undershoot drops to the original position, ready for the next filling

Applications of Rotary Tablet Press

1. Raw Material Compatibility

Rotary tablet presses are ideal for granular powders and materials with good flowability. However, they are not recommended for:

  • Sticky or semi-solid materials
  • High-moisture or heat-sensitive substances
  • Non-granular powders

2. Diversity in Shape and Size

Rotary tablet presses can compress powders or granules into tablets of various shapes, including round, oval, square, or customized designs. They support single or double-sided engraving and are suitable for:

  • Candy tablets
  • Calcium tablets
  • Double-sided imprinted tablets
