PNEUMATIC TRANSPORTING DEVICE FOR POWDER IN FLOUR MILLING ROLL MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a pneumatic transporting device for powder in a flour milling roll machine, having good followability to a sudden change in flow rate of powder and also estimating a future change in the flow rate of the powder.;SOLUTION: A stock level gage 35 is disposed in the vertical direction in the cylindrical supply part 16 of a supply hopper. The measured value of the stock level gage 35 is input to a control means 34, and the rotational frequencies of feed rolls 19, 20 are controlled to increase and decrease according to the stock level, and the air quantity of a pneumatic pipe 26 is controlled to increase and decrease according to the stock level.;COPYRIGHT: (C)2011,JPO&INPIT
