  烘干机热物理方法:人们把烘干机技术采用热物理方法去湿的过程称为“干燥”。其特征是采用加热、降温、减压或其他能量传递的方式使物料中的湿分产生挥发、冷凝、升华等相变过程与物体分离以达到去湿目的。不具备这一特征的去湿方法通常不列入干燥技术的范畴。
  Thermophysical method of dryer: People call the dehumidification process of dryer technology by thermophysical method "drying". It is characterized by the use of heating, cooling, decompression or other energy transfer methods to make the moisture in the material produce volatilization, condensation, sublimation and other phase transformation process and object separation in order to achieve the purpose of dehumidification. Dehumidification methods that do not possess this characteristic are usually not included in the scope of drying technology.
  有的烘干机技术去湿手段,例如液体被加热而浓缩,虽然也具备热物理法去湿的特征,但人们习惯上不认为浓缩属干燥技术。而随着时代的发展,人们却逐渐将一些不属于热物理法的去湿新技术纳入干燥技术的范畴,例如分子筛、超临界流萃取等。所以,干燥技术的定义与范畴是一个约定俗成的,而又在不断拓展的概念。
  Some dryer technology dehumidification means, such as liquid heated and concentrated, although it also has the characteristics of thermophysical dehumidification, but people are not accustomed to consider concentration as a drying technology. However, with the development of the times, some new dehumidification technologies which do not belong to thermophysical methods are gradually included in the drying technology category, such as molecular sieves, supercritical fluid extraction and so on. Therefore, the definition and scope of drying technology is a conventional and expanding concept.

  传统的工业生产烘干机技术普遍采用的干燥技术主要有:厢式干燥、隧道干燥、转筒干燥、转鼓干燥、带式干燥、盘式干燥、桨叶式干燥、流化床干燥、喷动床干燥、喷雾干燥、气流干燥真空冷冻干燥、太阳能干燥、微波和高频干燥、红外热辐射干燥等。这些传统的干燥技术发展历史较长、成熟可靠,在世界及我国已经得到广泛的应用。
  The main drying technologies commonly used in industrial production dryer include: trunk drying, tunnel drying, rotary drum drying, rotary drum drying, belt drying, disc drying, paddle drying, fluidized bed drying, spouted bed drying, spray drying, airflow drying, vacuum freeze drying, solar drying, microwave and high-frequency drying, infrared radiation drying, etc. These traditional drying technologies have a long history of development, maturity and reliability, and have been widely used in the world and China.
  近些年来,涌现出一批新型的烘干机技术,有脉冲燃烧干燥、对撞流干燥、冲击穿透干燥、声波场干燥、超临界流体干燥、过热蒸汽干燥、接触吸附干燥等等,这些新技术相对传统干燥技术在机理上有一定的突破,但在工业化应用方面仍有待于完善目前在我国这些新型的干燥技术还处于前期研究的阶段。
  In recent years, a number of new dryer technologies have emerged, such as pulse combustion drying, impinging stream drying, Impact Penetration drying, acoustic field drying, supercritical fluid drying, superheated steam drying, contact adsorption drying and so on. These new technologies have some breakthroughs in mechanism compared with traditional drying technologies, but still need to be improved in industrial application. The new drying technology is still in the early stage of research.
