Abstract

PURPOSE:To enable accurate detection of moisture in grain particles, by providing a controller to correct the moisture value of grain particles to a specified value as detected with a detection roll when a specified time elapses after the start of a burner. CONSTITUTION:A storage chamber 6 is provided up in the wall 5 of a dryer 4, a drying chamber 7 down therein and an operator 10 for controlling the start and stop of a burner 3 and the dryer 4 on the front panel of the wall 5. A grain lift 13 is mounted in front of the front panel of the wall 5 and pro vided with a moisture-measuring device 14 to detect the moisture of a part of grain particles to be supplied into the storage chamber 6. A hot air is generat ed from the burner 3 and the moisture value of the grain particles being detected with the measuring device 14 is corrected after a specified time passes but not when no air is generated from the burner 3. Thus, the moisture value in grain particles can be accurately detected regardless of any difference be tween the temperature of grain particles to be detected and that of a detection roll 2.

Conventional technology Conventionally, grains supplied by a feeding device are crushed by a detection roll under pressure, and at the same time, the moisture content of the crushed grains is detected and a target moisture setting knob is operated. This is a device that stops the grain drying operation when the moisture measuring device detects a grain moisture value that is the same as the finishing target moisture value set by the moisture measuring device. This was a measurement method in which the detected moisture value of grains detected by a roll was corrected by a predetermined value regardless of whether the burner was started or not.

Problems to be Solved by the Invention Grain stored in a dryer is exposed to hot air generated from a burner, and a portion of the grain being dried is supplied to a feeding device,
This feeding device feeds and transfers the supplied grains and supplies them onto a pair of detection rolls, and the supplied grains are crushed under pressure by the detection rolls, and at the same time, the moisture content of the crushed grains is detected. In the grain moisture measurement method, the detected moisture value is corrected by a predetermined value and this corrected value is displayed on the operating device as the detected detected moisture value. Although the grain temperature of the grain to be detected is high, the temperature of the detection roll is low, so unless the detected moisture value is corrected by a predetermined value based on the temperature difference between the two, an accurate grain moisture value will not be obtained. Since the grain temperature has not risen at the start of drying, the detected grain temperature and the temperature of the detection roll are the same at the outside temperature, so correcting the detected moisture value by the predetermined value will not result in an accurate grain moisture value. In some cases, when the drying of the grains is completed and the grains are stored in the dryer for a long time and then when the grains are discharged from the machine, moisture detection is performed for confirmation. Since the temperature of the grain detected in the same manner as described above is the same as the temperature of the detection roll, correcting the detected moisture value by the predetermined value may not result in an accurate grain moisture value.

Effect of the Invention For example, when a moisture measuring device is used in a dryer for drying grains, the grains stored in the dryer flow down from the storage chamber of the dryer into the lower drying chamber. While being circulated and dried while being exposed to hot air generated from the dryer (3), the drying grains are supplied from the dryer to the feeding device (1), which is driven by a pair of rotatably driven grains. The supplied grains are transferred one by one using a supply roll,
The supplied grains are fed onto a pair of detection rolls (2), (2), and are crushed between the outer peripheral surfaces of the detection rolls (2), (2) under pressure. After the hot air is generated from the burner (3), this detected moisture value is set and stored in the control device after a predetermined period of time has elapsed. The predetermined value is corrected, this corrected moisture value is displayed as the detected moisture value on the display window of the operating device, and this moisture content is set to the same grain moisture value as the finishing target moisture value set by operating the target moisture setting knob. When the measuring device detects this, the dryer is automatically stopped by the control device.

In addition, until the predetermined time set and stored in the control device has elapsed, and when the grains are discharged outside the machine without hot air being generated from the heather (3), the moisture is removed. When detecting the moisture content of grains with a measuring device, the detection rolls (2), (
The detected moisture value detected in step 2) is displayed as it is on the display window of the operating device without correcting the predetermined value that is set and stored in the control device.

Effects of the Invention According to this invention, hot air is generated from the burner (3) to increase the temperature of the grains being dried, and only when the moisture of the grains whose grain temperature has increased is detected, the detected moisture value is determined. By correcting, even when there is a difference between the grain temperature of the grain to be detected and the temperature of the detection row, it is possible to accurately detect the moisture content of the grain.
Further, when there is no difference between the grain temperature of the grain to be detected and the temperature of the detection roll, the detected moisture value is not corrected, so that the moisture of the grain can be accurately detected.

A portion of the grain is supplied through the supply roll (27), and the supplied grain is passed through the supply roll (27),
Grains are fed one by one into the spiral groove of (27), transported along this spiral groove, and dropped onto the detection rolls (2), (2) which are driven once, and are fed onto the detection rolls (2), (2). The grains are crushed under pressure between the outer peripheral surfaces of the burner (3), and the electric resistance value at the time of crushing is detected and stored in the control device (52) after hot air is generated from the burner (3). This detected electrical resistance value is replaced with the grain moisture value until a predetermined time.
