  一、按干燥设备操作压力分:
  1. According to the operating pressure of drying equipment:
  可分为常压式和真空式两类干燥设备。常压干燥设备的传热可以采用任何一种或几种型式同时传热,而真空干燥设备的特点是以传导传热和辐射传热居多,而且多数以间歇生产 方式为主,真空干燥设备主要处理热敏性物料和有溶剂回收的物料。
  It can be divided into two types of drying equipment: atmospheric pressure drying equipment and vacuum drying equipment. Atmospheric drying equipment can use any or several types of heat transfer at the same time. The characteristics of vacuum drying equipment are conduction heat transfer and radiation heat transfer, and most of them are intermittent production. Vacuum drying equipment mainly deals with heat sensitive materials and materials recovered from solvent.
  二、按干燥设备操作方式分类:
  2. Classification according to operation mode of drying equipment:
  按干燥设备操作方式可分为间歇操作和连续操作两类。
  According to the operation mode of drying equipment, it can be divided into intermittent operation and continuous operation.
  三、按被干燥物料的状态分类:
  Classification according to the state of the dried material:
  可以分为块状物料、带状物料、粒状物料、膏状物料、溶液或浆状物料干燥等,在许多情况下,物料的原始状态决定选择干燥器的型式。
  It can be divided into block material, strip material, granular material, paste material, solution or slurry material drying, etc. In many cases, the original state of the material determines the type of dryer.
  四、按干燥设备给热量方式分类:
  4. Classify according to the way of heat supply of drying equipment:
  按干燥设备给热方式可以分为对流加热干燥设备、传导加热干燥设备、其它(辐射加热、高频加热)以及多种传热方式的干燥设备等。
  According to the heating mode of drying equipment, it can be divided into convection heating drying equipment, conduction heating drying equipment, other drying equipment (radiation heating, high frequency heating) and a variety of heat transfer methods.
  五、按干燥设备的结构分类:
  Fifth, according to the structure of drying equipment:
  按干燥设备的结构可以分为喷雾干燥设备、流化床干燥设备、气流干燥设备、回转圆筒干燥设备、滚筒干燥设备、各种箱式干燥设备、带式干燥设备等。
  According to the structure of drying equipment, it can be divided into spray drying equipment, fluidized bed drying equipment, air drying equipment, rotary cylinder drying equipment, roller drying equipment, various box drying equipment, belt drying equipment and so on.
  六、按使用干燥介质的种类分类:
  6. According to the types of drying media used:
  对流换热可以分为空气、烟道气、过热蒸汽、惰性气体为干燥介质的干燥设备。传导传热可分为导热油、热水、蒸汽等。

  Convection heat transfer can be divided into air, flue gas, superheated steam, inert gas as drying medium drying equipment. Conduction and heat transfer can be divided into heat conducting oil, hot water, steam, etc.
  干燥设备的适用范围
  Scope of application of drying equipment
  所谓干燥就是通过给物料施加一定的能量使湿分(通常指水分)汽化、蒸发,从而除去湿分。干燥是一种传热与传质同时发生的分离过程。
  The so-called drying is to vaporize and evaporate moisture (usually water) by applying a certain amount of energy to the material, so as to remove moisture. Drying is a separation process in which heat and mass transfer occur simultaneously.
  被干燥物料及物料的状态、物理物性各不相同,至今还没有能够适应所有物料的干燥设备。因此选择干燥设备时重要的一点是要根据具体条件综合考虑选择想对合适的干燥设备,选取有利且可行的型式与运转条件。
  The state and physical properties of the dried materials and materials are different. So far, there is no drying equipment suitable for all materials. Therefore, when selecting drying equipment, it is important to select the most suitable drying equipment and the most favorable and feasible type and operation conditions according to the specific conditions.
  目前,工业用的干燥机按传热方法分类有对流、传导、辐射等型式。
  At present, industrial dryers are classified into convection, conduction and radiation according to heat transfer methods.
