The invention provides a bean dreg
drying device. The technical key point of the bean dreg
drying device is that the bean dreg
drying device comprises a material feeder, a multi-ring roller dryer and a multi-set
cyclone material
receiver; the material feeding end of the multi-ring roller dryer is connected with the material feeder, the material discharging end of the multi-ring roller dryer is connected with the material feeding end of the multi-set
cyclone material
receiver, and the material discharging end of the multi-set
cyclone material
receiver is connected with a material discharging and sorting
machine; one end of a heat exchanging
pipe of the multi-ring roller dryer is connected with a
smoke feeding
pipe, and the other end of the heat exchanging
pipe of the multi-ring roller dryer is connected with a first
smoke discharging pipe; the
smoke feeding pipe is connected with a smoke discharging pipe of a boiler, a smoke deduster is installed on the smoke feeding pipe, and a drying inlet
butterfly valve is installed on the position, in front of the smoke deduster, of the smoke feeding pipe; the first smoke discharging pipe is connected with the inlet end of the heat exchanging pipe of the multi-set cyclone material receiver, the outlet end of the heat exchanging pipe of the multi-set cyclone material receiver is connected with a second smoke discharging pipe, and an induced draft fan is installed on the second smoke discharging pipe; and a drying outlet
butterfly valve is installed on the position, behind the induced draft fan, of the second smoke discharging pipe. According to the bean dreg drying device,
moisture in bean dregs can be effectively and quickly removed, and the phenomenon that due to the
water content of the bean dregs is overlarge, the bean dregs are extremely prone to going bad is avoided.
