Development history of tablet press

Tablet computers appeared earlier in Europe and America, with a history of nearly a hundred years. In China, from 65438 to 0949, Shanghai Tian Xiang Ji Hua Iron Works copied the British 33 punch; 195 1 year was transformed into a domestic 18 punching machine according to the American 16 punching machine, which was the earliest pharmaceutical machinery manufactured in China. 1957 designed and manufactured ZP25-4 tablet press. 1960, 60-30 tablet press was successfully designed and manufactured by itself, with automatic rotary tablet pressing function. The pressed varieties are tablets, sugar tablets, calcium tablets, coffee tablets and so on. In the same year, ZP33 and ZP 19 tablet press were also designed and manufactured.

In 1970s, Shanghai No.1 Pharmaceutical Machinery Factory (the predecessor of Shanghai Tian Xiang) and Shandong Medical Instrument Factory, as designated manufacturers of tablet presses, began to mass-produce ZP series tablet presses. During the "Seventh Five-Year Plan" period, 206 HZP26 high-speed tablet presses were successfully developed by the Ministry of Aeronautics and Astronautics. 1980, Shanghai No.1 pharmaceutical machinery factory designed and manufactured ZP-2 1W tablet press, which reached the international advanced level in the early 1980s and was the first product in China. 1987 introduced the microcomputer control technology of Fette company of the Federal Republic of Germany, and designed and manufactured P3 100-37 rotary tablet press, which has the functions of automatically controlling the weight and pressure of tablets, automatically counting, and automatically eliminating waste tablets. The closed structure is tight, and the purification degree meets GMP requirements. 1997, Tian Xiang jiantai pharmaceutical machinery co., ltd developed ZP 100 series rotary tablet press and GZPK 100 series high-speed rotary tablet press.

2 1 century, with the deepening of GMP certification, ZP series rotary tablet presses which are completely in line with GMP appeared one after another: ZP35A in Shanghai, ZP35D in Liaocheng, Shandong, etc. High-speed rotary tablet press has made great progress in the technology of output, pressure signal acquisition and waste removal. Generally, the maximum output is above 300,000 tablets/hour, the maximum pre-pressure is 20kN, and the maximum main pressure is above 80kN or 100kN. For example, GZPLS-620 series high-speed rotary tablet press of Beijing Sinopharm Longli Technology Co., Ltd., GZPK3000 series high-speed rotary tablet press of Shanghai Tian Xiang Jiantai Pharmaceutical Machinery Co., Ltd., PG50 series high-speed rotary tablet press of Beijing Institute of Aeronautical Manufacturing Engineering, etc.

With the improvement of manufacturing technology and automatic control technology and the different special needs of tablet press manufacturers, various special tablet presses have appeared one after another. Such as laboratory ZP5 rotary tablet press, dry powder rotary tablet press for dry powder tablet press, explosion-proof ZPYG5 1 series rotary tablet press for powder tablet press, etc.
