Drying equipment how to run efficiently work

Abstracts:

Drying equipment is also known as dryers and driers. The purpose of drying is for material use or further processing needs. Such as wood in the production of wood molds, wood before the drying can prevent product deformation, ceramic blanks in the calcination of two drying equipment before the drying can prevent the finished product cracked. In addition, the dried material is also easy to transport and storage, such as the harvested grain dried to a certain moisture content below, in order to prevent mold and mildew. …

Drying equipment is also known as dryers and driers. The purpose of drying is for material use or further processing needs. Such as wood in the production of wood molds, wood before the drying can prevent product deformation, ceramic blanks in the calcination of two drying equipment before the drying can prevent the finished product cracked. In addition, after drying the material is also convenient for transportation and storage, such as the harvested grain drying to a certain moisture content below, in order to prevent mold and mildew. As the natural drying is far from being able to meet the needs of production development, a variety of mechanized dryer is more and more widely used.

  Drying process needs to consume a lot of thermal energy, in order to save energy, some materials with high moisture content, containing solids suspension or solution is generally first by mechanical dehydration or heating evaporation, and then dry in the dryer, in order to get dry solid.

  In the drying process needs to be completed at the same time the transfer of heat and mass (moisture), to ensure that the partial pressure of moisture vapor (concentration) on the surface of the material is higher than the partial pressure of moisture vapor in the external space, to ensure that the temperature of the heat source is higher than the temperature of the material.
  Heat from the high-temperature heat source in a variety of ways to the wet material, so that the material surface moisture vaporization and escape to the external space, so that the material surface and the internal moisture content difference. Internal moisture to the surface of the diffusion and vaporization, so that the moisture content of the material continues to reduce, and gradually complete the drying of the material as a whole.
