The drying process requires a lot of thermal energy, in order to save energy, some material having high wet content, a suspension or solution containing a solid substance, which is generally mechanically dehydrated or heated, and then dried in the dryer to give dry solid. Q35 China Feed Industry Information Network – Based on Feed, Service Animal Husbandry
In the drying process, the transfer of heat and quality (moist) is required, ensuring that the surface wet steam partial pressure of the material ( The concentration) is higher than the moisture steam partial pressure in the outer space, ensuring that the heat source temperature is higher than the material temperature. Q35 China Feed Industry Information Network – Based on Feed, Service Animal Husbandry
The heat is passed from the high temperature heat source to the wet material in a variety of ways, so that the material surface moist is moist and evaporated. Thereby the difference in wet content in the surface of the material surface and the interior. The internal moistosis is diffused and vaporized, so that the material wet content continues to decrease, and the overall amount of the material is gradually completed. Q35 China Feed Industry Information Network – Based on Feed, Service Animal Husbandry
Depending on the rate of diffusion rate of surface vaporization rate and internal moisture. Usually, the dry rate of the previous period is controlled by the surface vaporization rate; then, as long as the dry external conditions are unchanged, the drying rate of the material and the surface temperature are stable, and this stage is referred to as a constant speed drying stage; when the material wet content is lowered to some The degree, the diffusion rate of the internal moistosis surface is reduced, and when the surface vaporization rate is reduced, the drying rate is mainly determined by the internal diffusion rate, and the decrease in the amount of wet content is continuously reduced, and this stage is referred to as a reduction drying stage.
