title: [Research and application of far-infrared rays to drying Chinese medicinal herbs in small pieces].
abstract: OBJECTIVE
  To introduce a far-infrared ray dryings device.
  
  
  METHODS
  The research background, work tenets, structure, function, technical parameters and tentative application of the device were reported. Chinese medicinal herbs in small pieces which contain volatile oils were dried by far-infrared rays and airing. The two drying methods were compared.
  
  
  CONCLUSIONS
  Not degrading the quality of medicinal herbs in small pieces, the device can be used to dry various kinds of medicinal herb pieces and thus deserves popularization.
