Document Type and Number:
Japanese Patent JP2018151122
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To solve a problem that a detection error occurs if a threshold for abnormality detection is uniformly applied, since the inner pressure of a dust discharge device fluctuates depending on the kind of grain and a circulation condition.SOLUTION: A grain dryer according to the present invention comprises a storage chamber (2) that stores grain and a drying chamber (5) that circulates and dries grain, each disposed in a box body (1), and includes: a dust discharge fan (21) that sucks and discharges dust in the storage chamber (2) to the outside of the dryer; a pressure sensor (29) that detects the pressure of sucked air flowing through a dust discharge device (24); determination means of determining whether a value of a pressure detected by the pressure sensor (29) is abnormal or not; and means of changing a threshold for determining abnormality of a detected value according to the kind of grain.SELECTED DRAWING: Figure 8
