烘干机的烘干能力与物料的干湿程度有关,不是说任何物质在相等的时间里都可以达到很好的效果。它也与热源的选择有关。高湿的物料,如果烘干不充分,烘干出来的物料就会略带潮湿,而热源的选择,也是很关键的。
  The drying capacity of the dryer is related to the drying and wetting degree of the material, not that any material can achieve good results in the same time. It is also related to the choice of heat sources. If the drying of high humidity material is not enough, the material will be slightly humid, and the choice of heat source is also critical.
  选择热源很重要,作为烘干设备配套的热源设备很多,通常是按消耗的燃料来分类,有燃煤、燃油、燃气、电力等,按换热情况又可分为干燥介质直接加热和间接加热。如锅炉加热水形成水蒸汽,水蒸汽再通过散热器加热干燥介质,这就是两次间接加热,这种方式总的热效率很低,仅40%左右,在某些工厂生产中有多处用热点,为便于集中供热和管理,采用较多。
  Choosing heat source is very important. There are many heat source equipments for drying equipment. They are usually classified according to the fuel consumed. They are coal-fired, oil-fired, gas-fired, electric power and so on. According to the heat transfer situation, they can be divided into direct heating and indirect heating of drying medium. For example, the boiler heates water to form water vapor, and then the water vapor heates the drying medium through the radiator, which is two indirect heating. The total thermal efficiency of this method is very low, only about 40%. In some factories, there are many hot spots in production. In order to facilitate the centralized heating and management, it is more used.

  从工业环保的角度来讲,烘干机是极其有利于我国环保的可持续发展。在选购烘干机的过程中一定要明白自己的需求,如果设备功率不够,物料就会出现烘干不理想的状态,达不到烘干要求。所以在选择烘干机的时候,要明确的得知烘干的产量,物料的初始含水量,终含水量,来计算需要多少热能,然后计算需要多少的耗电量等等。
  From the perspective of industrial environmental protection, dryer is extremely conducive to the sustainable development of environmental protection in China. In the process of choosing and purchasing dryers, we must understand our own needs. If the power of the equipment is not enough, the material will be in an unsatisfactory state of drying, which can not meet the drying requirements. So when choosing the dryer, we should know clearly the drying output, the initial moisture content of the material, the final moisture content, to calculate how much heat energy is needed, and then calculate how much power consumption is needed and so on.
