の穀粒水分で乾燥制御が行なわれる方式であった。Conventional technology Conventionally, in a grain dryer equipped with a moisture sensor that controls drying while detecting the moisture in the grains being dried, when this moisture sensor detects moisture in green rice and grains other than fine grains, In this method, the water content of these green rice and grains was cut off, and drying was controlled using only the grain water content of fine grains.

て穀粒の乾燥が停止される。Problems to be Solved by the Invention A part of the grains being dried is loaded one by one, for example, 50 grains, at predetermined time intervals using a moisture sensor, and at the same time, the grains are crushed under pressure. Detects moisture in crushed grains,
During this moisture detection, if an abnormally high moisture content is detected, the moisture content of the green rice is detected and the process is cut, and if an abnormally low moisture content is detected, the coarse grains are detected and the cut process is performed. The average calculated value is used as the detected grain moisture. When this detected grain moisture becomes the same as the set finishing target moisture, the grain dryer is automatically stopped and the drying of the grain is stopped. Ru.

ことがあった。Since the grains with this green rice mixed in are detected as grain moisture at the time of delivery, green rice has a higher moisture content than fine grains than the grain moisture of only fine grains during drying. As a result, the moisture content of the grains is often high due to the amount of green rice mixed in, and this results in a difference between the moisture content of the grains at the end of drying and the moisture content of the grains after hulling. In some cases, the grains had a moisture content higher than the limit moisture content and could not be delivered.

乾燥が停止される。Means for Solving the Problems This invention is a grain dryer equipped with a moisture sensor (1) that controls drying while detecting the moisture content of grains during drying. By specifying this, the detected moisture content is automatically corrected based on the designated green rice mixing ratio to perform drying control. The sensor (1) greens grains one by one at predetermined time intervals, for example, 50 grains.
At the same time as the grains are crushed under pressure, the moisture content of the crushed grains is detected, and when detecting the moisture content, the proportion of green rice mixed into the refined grains is specified, and the specified green rice proportion is set to 10%. If it is specified that there is an abnormally high moisture content in the grain, it will be assumed that moisture in green rice has been detected, and 90% of the detected number of detected green rice grains will be cut. When low moisture is detected, coarse grains are detected and processed to be cut, and an average value is calculated from these 50 fine grains and 10% green rice of the number of detected grains, and this average value is calculated as the detected grain. When the moisture sensor (1) detects grain moisture equal to the finishing target moisture, the dryer is automatically stopped and the drying of the grains is stopped.

水分不良による供出不能が発生することがなくなった。Effects of the Invention According to this invention, when the mixing ratio of green rice to be mixed into fine grain after hulling is specified and the water content of green rice is detected during moisture detection, the water content of old rice within this specified mixing ratio is determined. By incorporating it into fine grains and calculating the average value, it is possible to determine the mixing ratio of green rice that would have been mixed in the grains during drying, and the mixing ratio of green rice that was set when the grains were hulled. By removing green rice up to 100%, the mixing ratio of green rice mixed into fine grain after hulling becomes the same, and the grain moisture detected at the time of offering after hulling and the grain moisture at the end of drying. The moisture content of the grains detected at the time is the same because the mixed ratio of green rice is the same, and therefore, the failure to supply due to insufficient moisture no longer occurs.

It is a systemized device that performs a series of drying work, hulling work, and weighing work using a weighing machine that weighs grains, and when the green rice mixing ratio is specified to the weighing machine, this specified value is transferred to the dryer (2) side. Automatically reads the detected green rice moisture in the same amount as the green rice mixing ratio of this reading into the detected fine grain moisture, and calculates the grain moisture based on this detected green rice moisture and this detected fine grain moisture. death,
The moisture obtained by this calculation is used as the detected grain moisture to control the drying of the grain. As a result, the ratio of green rice mixed in the grains detected during drying and the ratio of green rice mixed in after paddy WI become the same value, so that the grain moisture at the end of drying and this grain Since the grain moisture is the same as when the rice is hulled to a predetermined green rice mixing ratio, problems will not occur in the grain moisture after hulling.
