Classification of tablet press: Models can be divided into single punch tablet press, rotary tablet press, sub-high speed rotary tablet press, automatic high speed tablet press and rotary core tablet press.
The sheet shape pressed by the tablet press is initially flat circular, and later developed into shallow circular arc and deep circular arc on both sides, which is for the need of coating. With the development of special-shaped tablet press, oval, triangle, oblong, square, diamond, circular ring tablets followed. In addition, with the continuous development of preparations, due to the requirements of compound preparations and timed release preparations, special tablets such as double layer, triple layer and core coating are made, which need to be completed on special tablet press.
Rotary tablet press is a machine which is made of several pairs of die distributed on the turntable to make a circular lifting movement according to a certain track and press the granular material into tablet through the press wheel. And the stamping rod with the rotary table rotating speed ≥60m/min line press is called high-speed rotary tablet press, this high-speed rotary tablet press has a forced feeding mechanism, the machine is controlled by PLC, has the automatic adjustment of pressure, control the weight of the piece, eliminate the waste piece, print data, display fault shutdown and other functions, in addition to the control of the weight difference within a certain range, Quality problems such as missing Angle and loose lobe can be automatically identified and eliminated.
With the development of market demand, the scope of application of tablet press is more and more wide, no longer simply limited to the suppression of Chinese and Western medicine tablets, more widely suppressed health food, veterinary medicine tablets, chemical tablets: such as mothballs, washing blocks, smurf blocks, art powder, pesticide tablets, food tablets: chicken essence block, isatis root block, divine Qu tea block, compressed biscuits.

The large-scale cryogenic technology in the liquid hydrogen temperature zone is a major key technology that has long affected China's aerospace industry and the forefront of scientific development, especially the large-scale low-temperature refrigeration technology required for aerospace engineering. The developed countries have always imposed a technical blockade on China.
In order to break the long-term passive situation, the researchers of the Chinese Academy of Sciences have adhered to the path of independent innovation on the basis of decades of accumulated low-temperature technology. Through more than four years of hard work, China has achieved a low-temperature cooling capacity of 10,000 watts in the liquid hydrogen temperature zone. Zero breakthrough in equipment development. Researchers have broken through five key technologies such as high-speed gas bearings, turboexpanders, and established five basic test platforms, and formed core technologies and technological packages with independent intellectual property rights. The comprehensive performance of equipment has reached the international advanced level.
The large-scale low-temperature refrigeration equipment developed by Chinese scientists in the liquid hydrogen temperature zone has broad application prospects in aerospace, large-scale scientific projects, clean energy and other fields. Related equipment has been successfully applied to aerospace product performance testing, and has enhanced the research and development capabilities of aerospace products.
At the acceptance meeting, experts agreed that the completion of the project has broken the monopoly of large-scale low-temperature refrigeration technology in the liquid hydrogen temperature zone in developed countries and laid the foundation for independent development of serialized products. It is a major scientific research with strong integration and engineering. Equip with independent innovation and industrialization model has accumulated valuable experience.
At present, the Chinese Academy of Sciences has started the second phase of the development of large-scale cryogenic refrigeration equipment. It will develop large-scale low-temperature equipment (liquid helium/superfluid helium) and promote the continuous development of large-scale cryogenic refrigeration technology.
The National Large Scientific Research Equipment "Development of Large-scale Low-temperature Refrigeration Equipment" supported by the Ministry of Finance and the Institute of Physical and Chemical Technology of the Chinese Academy of Sciences passed the acceptance on the 29th. It is reported that this equipment can not only meet the needs of the national strategic high-tech development of large scientific projects, aerospace engineering and other large-scale refrigeration equipment in the liquid hydrogen temperature zone, but will also promote the development of advanced technologies in related fields.
