Tablet presses are getting more and more attention from the market

It is understood that the earliest press machine consists of a pair of die, and later developed into electric basket type tablet press. The operating principle of these two types of tablet presses is a one-way tablet pressing based on a manual stamper, that is, when the tablet is pressed and fixed under the punch, only the upper punch pressurizes. This tableting method, due to inconsistent forces on the top and bottom, results in uneven density inside the tablet, and is prone to problems such as splitting.

For the shortcomings of the unidirectional tablet press, a rotary multi-punch bidirectional tablet press was born. The tableting machine presses up and down at the same time and pressurizes uniformly, so that the air in the drug particles has ample time to escape the die hole, which improves the uniformity of the tablet density and reduces the phenomenon of cracks. In addition, the rotary tablet press also has the advantages of small machine vibration, low noise, low energy consumption, high efficiency and accurate tablet weight. With the development of automation technology, automatic high-speed tablet press has won the favor of the market.

With the development of market demand, the application range of tablet presses is becoming wider and wider. It is no longer confined to the suppression of Chinese and western medicine tablets, but it can also be widely used to suppress health foods, veterinary medicine tablets, and chemical tablets: such as mothballs. Sanitary balls, washing blocks, blue spirits blocks, art powder cakes, pesticides tablets, etc., food tablets: chicken essence pieces, Banlangen pieces, Shenqu tea pieces, compressed biscuits, etc.

According to industry insiders, the speed of tablet presses has a direct impact on machine life, tablet weight, and tablet quality. Because of the nature of the particles, viscosity, water content, particle size distribution, and size of the particles, the pressure is different. Therefore, a unified law cannot be established. It can only be determined based on actual conditions and experience of technicians. The tablet press can press all kinds of granular raw materials into round discs, suitable for laboratory trial production or small batch production of various tablets, sugar tablets, calcium tablets, special-shaped tablets and so on. Generally can provide various shapes of mold according to customer requirements.

Judging from the current situation, China's tablet press industry has a low technological content and lacks technical innovation. Although new products are introduced every year in China, there are few varieties with high real technical level and large added value. In addition, the repeated development of products is serious. Some small-scale pharmaceutical equipment companies not only adopt "imitation-type" strategies in technological innovation, but also some manufacturers almost rely on plagiarism of others as their own technological "innovation." What's more, in order to compete for orders, they often resort to price cuts.

Compared with foreign advanced technologies, China's tablet press industry still has a large gap. How to narrow the gap is an issue that companies need to consider. In the face of an increasingly fierce market competition environment, China's tablet press industry needs to continuously strengthen independent innovation, instead of adopting a "imitation-type" strategy; it needs to deeply digest foreign advanced technologies, not just plagiarism; it needs a pragmatic attitude rather than a big fight." Price war."

In addition, the author has learned that dust is the most troublesome problem in the tablet press industry, but currently effective treatment methods have not been produced. At present, there are various types of tablet presses on the market in China. These tablet presses are used in the production of dust. A vacuum cleaner is generally used to provide negative pressure to remove the suction. However, due to the limited level of the existing technology, the sealing effect of most tablet presses in China is not ideal, and some dust is still leaked to the purification zone. In addition, the dust generated during the process of material transfer or tablet transfer may also be directly leaked from the connection point to the decontamination zone, causing cross-contamination of the final produced tablets or affecting the safety of the drug.

Therefore, while improving the equipment technology and innovation, tablet machine manufacturers need to consider the dust problems of the tablet press as appropriate, so that the equipment can achieve true green production and energy-saving production.
