What equipment is needed to dry the bean dregs? It is preferred to know the initial water content of the bean dregs and the water content of the dry bean dregs. If the water content of the dry bean dregs is about 60%, then a bean dregs belt dewatering machine can be realized, but the dry bean dregs water content is about 12%, generally, a complete set of special machines for drying bean dregs is used.
The deep dehydration of the bean dregs requires high-temperature and strong drying. The wet bean dregs passing through the belt dewatering machine enters the paddle-type stirring bean drier tumble dryer under the action of the loose feed conveyor, and the stirring blade device and the shock cleaning device are arranged. In the drum, the wet potato slag is spirally advancing, heat exchange with the heat medium in the raised area with a larger heating area, and rapid evaporation, reaching the pulverizer at a state of 35% water, reaching a particle size of 1 mm. The state enters the pulse airflow drying process, thereby achieving the moisture content of the dry potato slag by about 12%, completing the entire drying process.The moisture content of dry bean dregs can reach about 12%, effectively extending the shelf life.
The bean dregs dryer has a special type, mainly because the starch content of the bean dregs is high. In the environment with large moisture, it is easy to bond and stick to the wall, so that the ordinary tumble dryer is easy to paste and stick walls, and damage the bean dregs dryer, reduces the drying efficiency and quality of the bean dregs. Therefore, the dispersing and cleaning devices are mainly for high-humidity materials such as bean dregs with a large amount of water and starch.
