Tablet press: (1) press machine, the dry granular or powder material through the mold pressing into the tablet machinery. (2) single punch tablet press, a tablet press for vertical reciprocating movement of a pair of dies. (3) the rotary press machine consists of a plurality of sub dies which are uniformly distributed on the rotating turntable, and a vertical reciprocating motion press machine is carried out according to a certain trajectory. (4) high speed rotary tablet press, the axis of the die rotates at the same speed as the turntable, and the rotary tablet press is not less than 60m/min.
  On the tablet machine, the earliest in Europe and the United States is making up the test area, has a hundred years of history, the first Department of pharmacy, however Chinese is in 1949 began the introduction of foreign technology, and until now, the domestic tablet machine is generally used by a few decades China's tablet machine technology. But compared with foreign countries, there are still some gaps, such as: General technical content is low, the technology innovation is not enough, China's machine manufacturers in more than 40 or so, but the scanty real strength of the manufacturers, product re development of serious plagiarism rife. In China, the majority of tablet press manufacturers are private enterprises, in terms of technology, equipment, talent and other advantages, so the domestic press machine technology for foreign countries, there is still a certain gap.
  The development direction of foreign tablet press is intelligent, precise and meets the requirements of GMP. The high and new technology content of products is continuously sublimated, and the man-machine interaction is convenient and quick. Then, the domestic press machine design, manufacturing aspects are inadequate, we still need to strive to develop new and high technology, break through all technical bottle diameter, and strive to catch up with the world tablet machine level ranks.
