Embodiments Next, embodiments will be described in detail with reference to the drawings. Figure 1
The whole grain dryer A which implements the means of this invention is a perspective view, and FIG. 2 shows the longitudinal front view of the grain dryer A same as the above.

In FIG. 1 and FIG. 2, the grain dryer A is an elevator 2 which stands on the front surface of a box-shaped machine body 1.
Operation, the rotary shutter 10 and the elevator 2 and the rotary shutter 1 installed on the bottom side of the machine body 1 with a predetermined amount of the grain stored in the grain storage portion 1a of the machine body 1 are operated.
0 By the operation of the grain feeding means such as the lower discharge conveyor 11, it is carried out from the storage section 1a through the lower drying section 1b to the discharge trough 12 below the rotary shutter 10 to the outside of the machine, and again by the elevator 2. It is circulated so as to return to the storage section 1a in the machine body 1, and during this period, it is generated by the burner device 3 for generating hot air mounted on the front surface of the machine body 1 and by the operation of the blower 4,
The grain dryer is of a circulation type in which the grains are exposed to the hot air sent to the drying unit 1b for drying.

In this grain dryer A, the hot air supplied to the circulating grain is generated by the operation of the burner device 3 provided on the front side of the machine body 1 described above, and the hot air is generated on the rear side of the machine body 1. Blower 4 attached to the exhaust duct 13 provided in the
2, the hot air guide passage 14 is passed across the grain flow-down passage 15 to the exhaust passage 16 as shown by the double-lined arrow in FIG. In the suction form in which the blower 4 discharges the air from the above-mentioned exhaust duct 13 through the exhaust port 17 which is opened in the air passage, while the hot air flowing in this way crosses the grain downflow path 15, The grains are fed to the grains flowing down the grain flow path 15.

The burner unit 3 for generating the hot air, the blower 4 for guiding the generated hot air, and the grain feeding means such as the elevator 2, the rotary shutter 10 and the discharge conveyor 11 for circulating the grain are operated by the body 1.

[0044]

As described above, the grain moisture value display device in the grain dryer according to the present invention is provided with the grain dryer A.
Is being operated to perform the drying operation of the grain, the grain being dried which is detected by the grain moisture value measuring device 6 equipped in the grain dryer A so as to operate every predetermined time. To display the water content f of a grain, use letters, numbers,
A screen display a that can freely draw a picture on the screen is used, and the moisture values f of the grain detected by the grain moisture value measuring device 6 at predetermined time intervals are arranged on the coordinate points sequentially in time series. Is displayed as a graph 81, the moisture value f at each detected time is displayed, and the state of change in the detected moisture value can be known at a glance. When there is a turbulence in the change of No., it becomes information indicating that the moisture value f of the dried grain has many variations and many unripe rice, and the allowance such as the rest drying can be effectively performed. If the moisture content changes slowly with time, the information will indicate the condition to switch to high-speed drying at high temperature. Conversely, if the moisture content changes rapidly with time, low-speed drying at low temperature is recommended. This is information that indicates the state to be switched. For this reason, the moisture value of the displayed grain can be effectively used to dry it up to a high quality grain.

Further, in addition to the moisture value of the grain detected by the grain moisture value measuring device 6, the detected value of the hot air temperature detected by the temperature sensor Se is graphed as coordinate points sequentially arranged in parallel with time. When it is displayed, if there is a turbulence in the change over time of the hot air temperature value displayed in the graphic, the window of the air exhaust path 16 of the machine 1 of the grain dryer A is open, or This is information such as a failure in the burner device 3 or the temperature sensor Se.
