First, the heat balance Continuous dryer heat balance are based on the unit time. Intermittent drying equipment is based on a dry cycle. In calorie accounting, various possibilities should be considered. The actual drying process can be simplified according to the actual situation. In the theoretical drying, the gas has a constant enthalpy. The drying process in theoretical drying is an isenthalpic process.
Second, the quality of (material) in the drying machine dryer belt to maintain a constant value for the amount of wet air flow in the amount of dry air, and dry and dry material out of the dryer quality. The moisture content of the continuous dryer is equal due to the entry and discharge.
