Several aspects of the tablet machine to be improved

The tablet press is mainly used for the tablet technology research of the pharmaceutical industry. With the development of science and technology and the improvement of people's living standards, tablet medicines are more and more preferred by patients because of their advantages such as simple taking and convenient carrying, and tablet presses will also receive more and more attention from the market. With the improvement of manufacturing process technology, 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 was composed of a pair of dies, and later developed into an electric flower basket type tablet press. The working principle of these two types of tablet presses is unidirectional tabletting based on manual die-pressing, that is, the tablet is fixed under the punch and only presses up. In this tableting method, due to the inconsistent force on the top and bottom, the density inside the tablet is uneven, and problems such as splitting are likely to occur.

In view of the shortcomings of the unidirectional tablet press, a rotary multi-punch bidirectional tablet press was born. The tablet press is punched up and down while being evenly pressurized, so that the air in the drug particles has enough time to escape from the die hole, which improves the uniformity of the tablet density and reduces the phenomenon of splitting. In addition, the rotary tablet press has the advantages of low machine vibration, low noise, low energy consumption, high efficiency and accurate tablet weight. With the development of automation technology, the production of automatic high-speed tablet press has won the favor of the market.

With the development of market demand, the scope of application of tablet presses is becoming wider and wider. It is no longer limited to the compression of Chinese and Western medicine tablets, but can also be widely used to suppress health foods, veterinary medicine tablets, chemical tablets: such as camphor pills Hygienic balls, washing blocks, smurf blocks, fine powder, pesticide tablets, etc. Food tablets: chicken essence blocks, Banlangen blocks, Divine Comedy tea blocks, compressed biscuits, etc.

Industry sources said that the speed of the tablet press has a direct impact on the machine life, tablet weight, and tablet quality. Due to the different nature of particles, viscosity, water content, particle size distribution, particle size, and pressure, it is impossible to make a unified law, which can only be determined according to the actual situation 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, shaped tablets, etc. Generally can provide molds of various shapes according to customer requirements.

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

Compared with foreign advanced technology, China's tablet press industry still has a big gap. 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, rather than adopt the "imitation" strategy; it needs to deeply digest advanced foreign technology, rather than blindly copy; 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 treatment methods have not been produced. At present, there are many kinds of tablet presses on the Chinese market. These tablet presses generally use special vacuum cleaners in the production of dust Provide negative pressure to eliminate suction. However, due to the limited level of existing technology, the sealing effect of most tablet press equipment in China is not ideal, and some dust still leaks to the purification area. In addition, the dust generated in the process of material transportation or tablet reordering may also be directly leaked from the relevant joints to the purification area, causing cross-contamination to the final produced tablets or affecting the safety of drugs.

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