Several aspects of tablet press to be improved

The tablet press is mainly used for tablet technology research in the pharmaceutical industry. With the development of science and technology and the improvement of people's living standards, tablet drugs are becoming more and more favored by patients due to their advantages such as easy to take and convenient to carry. Tablet presses will also receive more and more attention from the market. With the improvement of manufacturing process level, automation control technology and various special needs of tablet press manufacturers, various special purpose tablet presses have also appeared one after another.

It is understood that the earliest tablet press consisted of a pair of dies, which later developed into an electric flower basket tablet press. The working principle of these two tablet presses is a one-way compression based on manual compression molds, that is, the lower punch is fixed and only the upper punch moves for pressure. Due to the inconsistency of the upper and lower forces in this method of tablet compression, the density inside the tablet is uneven, and problems such as splitting are prone to occur.

　　 In response to this shortcoming of the unidirectional tablet press, a rotary multi-punch bidirectional tablet press was born. The tablet press presses up and down at the same time uniformly, so that the air in the drug particles has ample time to escape the die hole, improves the uniformity of the tablet density, and reduces the phenomenon of splitting. 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, the emergence of automatic high-speed tablet presses has won the favor of the market.

With the development of market demand, the scope of application of tablet presses has become wider and wider. It is no longer simply limited to compressing Chinese and Western medicine tablets, but can also be widely used to compress health food, veterinary medicine tablets, and chemical tablets: such as camphor pills. Sanitary ball, washing block, Smurf block, art powder cake, pesticide tablet, etc., food tablet: chicken essence block, isatis root block, divine song tea block, compressed biscuits, etc.

　　 Insiders said that the speed of the tablet press has a direct impact on the service life of the machine, tablet weight, and tablet quality. Due to the difference in particle properties, viscosity, water content, particle size distribution and sheet diameter, and pressure, a unified law cannot be made and can only be determined based on actual conditions and the experience of technical personnel. The tablet press can press various granular raw materials into round tablets, which is suitable for laboratory trial production or small batch production of various tablets, sugar tablets, calcium tablets, special-shaped tablets, etc. Generally, molds of various shapes can be provided according to customer requirements.

　　 From the current point of view, my country's tablet press industry has low technological content and insufficient technological innovation. Although new products are continuously introduced every year in our country, there are very few products with high technical level and great added value. In addition, repeated product development is serious. Some small-scale pharmaceutical equipment companies not only adopt an "imitation" strategy in technological innovation, but some manufacturers almost rely on copying other people's technology as their own technological "innovation". What's more, in order to compete for orders, prices are often reduced.

　　 Compared with foreign advanced technology, there is still a big gap in my country's tablet press industry. How to narrow the gap is what companies need to consider. Facing the increasingly fierce market competition environment, China’s tablet press industry needs to continuously strengthen independent innovation instead of adopting an "imitative" strategy; it needs to deeply digest foreign advanced technology instead of blindly copying; it needs a pragmatic attitude, not a big fight. Price war".

In addition, dust is the most troublesome problem in the tablet press industry, but the current effective solutions have not been produced. At present, there are various tablet presses on the market in China. These tablet presses generally use special vacuum cleaners in the dust produced. Provide negative pressure to suck it out. However, due to the limited level of existing technology, most of the tablet press equipment in our country has an unsatisfactory sealing effect, and some dust still leaks to the purification area. In addition, the dust generated in the process of material transportation or tablet reversal may also leak directly from the relevant connection to the purification area, which may cause cross-contamination of the final produced tablets and affect the safety of the medicine.

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