Tablet presses in Europe and the United States appeared earlier, with a history of nearly 100 years. And in China to 1949, Shanghai's Tianxiang Huaji iron factory imitation into the British-style 33 punch tablet press; 1951, according to the U.S. 16 punch tablet press converted into domestic 18 punch tablet press, which is the earliest domestic manufacturing of pharmaceutical machinery; 1957, designed and manufactured ZP25-4 tablet press; 1960, designed and manufactured their own successful 60-30 type tablet press, with automatic rotation and The function of pressing tablets, pressing varieties of tablets, sugar tablets, calcium tablets, coffee tablets, etc.. The same year also designed and manufactured the ZP33, ZP19 type tablet presses.
In the 1970s, Shanghai First Pharmaceutical Machinery Factory (the predecessor of Shanghai Tianxiang) and Shandong Medical Equipment Factory started to produce ZP series tablet presses in large quantities as the designated manufacturers of tablet presses. During the "Seventh Five-Year Plan", the Ministry of Aeronautics and Astronautics 206 HZP26 high-speed tablet press was successfully developed. 1980, Shanghai First Pharmaceutical Machinery Factory designed and manufactured the ZP-21W tablet press, which reached the international advanced level in the early 1980s and was the first product in China. 1987, the introduction of the Federal German Fette In 1987, Shanghai First Pharmaceutical Machinery Factory designed and manufactured the P3100-37 rotary tablet press, which has the functions of automatic control of tablet weight and pressure, automatic tablet counting, automatic rejection of waste tablets, etc. The closed structure is tight and the degree of purification meets GMP requirements. tablet presses.
In the 21st century, with the deepening of GMP certification, ZP series rotary tablet presses that fully comply with GMP have appeared one after another: ZP35A in Shanghai, ZP35D in Liaocheng, Shandong, etc. High-speed rotary tablet presses have made great development in terms of output, pressure signal acquisition and waste picking technology, and the highest output is generally greater than 300,000 tablets/hour, with a maximum pre-pressure of 20kN and a maximum main pressure of 80kN or 100kN or more. For example, the GZPLS-620 series high-speed rotary tablet press of Beijing Sinopharm Longli Technology Co., Ltd, the GZPK3000 series high-speed rotary tablet press of Shanghai Tianxiang Jiantai Pharmaceutical Machinery Co.
With the improvement of manufacturing and processing technology, automation control technology and the different special needs of tablet press manufacturers, various special-purpose tablet presses have emerged one after another. For example, ZP5 rotary tablet press for laboratory use, dry powder rotary tablet press for dry powder pressing, explosion-proof ZPYG51 series rotary tablet press for gunpowder tablets, etc.
