Air Dryer of Starch Processing Plant
2016-11-18In the starch processing plant, we often take air flow starch drying machine which also known as rapid drying for the entire process time is completed in a flash.So the starch granules within the water too late gelatinization has been drying, it will not gelatinization or degradation phenomenon.
Air flow starch drying process is a co-current drying process, that is wet powder materials and hot air flow and the process of heat and mass transfer from the two processes. When the wet starch in contact with hot air, the hot air to the heat transfer to the wet starch surface, and then transferred from the surface to the inside, this process is the heat transfer process; At the same time, wet starch moisture from the material within the liquid or gaseous Spread to the starch surface, from the starch surface through the film spread to the hot air to go, this is a mass transfer process. Is to high-temperature airflow and wet starch balance in the drying tube for heat exchange, so that the starch was dry powder, cooled package can be loaded into the library.
(Wet material through the conveyor and heated natural air into the dryer at the same time, the two fully mixed, due to heat exchange area, which in a very short period of time to achieve the purpose of evaporative drying.The dried product from the cyclone Discharge, a small part of the fly ash by the cyclone or bag filter to be recycled.)
