ることが困難であった。By the way, in the method of measuring the initial moisture value in the conventional dryer described above, the initial moisture value of the entire grain to be dried loaded in the dryer is determined by measuring the moisture of a very small amount of sample grain. However, the moisture value of the grain to be dried that is loaded into the dryer varies, and the moisture value varies greatly between storage bags or even within a single storage bag, so a small amount of sample grain is extracted after loading is completed. Even if the moisture value is measured, it is not possible to obtain an accurate initial moisture value.
In the conventional method, it was difficult to properly automatically dry the 5# grain to be dried without causing problems such as under-drying, over-drying, or cracking of the grain.

。Therefore, in order to eliminate the drawbacks of the conventional methods as described above, the present invention has been developed to measure the initial amount of the entire grain to be dried loaded in the dryer by measuring an amount that can represent the entire amount at relatively short intervals. Accurately measure the moisture value and its standard deviation, and even during circulation drying, accurately measure the average moisture value and its standard deviation of the whole grain using the same measurement method as above, and control drying and simmering by using these all 5 circles. The purpose of this invention is to obtain a grain drying method that can be carried out properly at all times.

乾燥製品を得ることができる効果を奏する。In view of the foregoing, in order to achieve the above object, the present invention includes a method for extracting sample grains from grains to be dried during drying in a dryer many times, and measuring the total water content of each of these extracted sample grains. The grain drying method is characterized in that the average initial moisture value and the standard deviation of each moisture value are determined, and the drying control is performed using the average initial moisture value and the standard deviation. According to this grain drying method, even if the moisture content of the grain to be dried loaded in the dryer varies depending on the storage bag, for example, the exact initial moisture content of the entire grain to be dried loaded in the dryer can be determined. If it is calculated that the width of the moisture value distribution of the population is too large compared to the average moisture value, the average moisture value can be calculated from the accurately determined initial moisture value and standard deviation. The drying air temperature is controlled to be slightly colder (for example, air at a temperature 5°C lower) than the drying air temperature that is appropriate for drying grains with a moisture content, and the drying temperature is This has the effect that it is possible to always obtain a high-quality dried product without causing cracks or over-drying.

All controls such as heating of drying air are carried out according to the ratio of the width of moisture value S of the population to the average moisture value from the standard deviation of moisture values measured many times, and the shell cracking of grains to be dried is performed. It is also possible to completely prevent disadvantages such as occurrence of C and retraction (C), and to control drying so as to dry efficiently.

せることができる。Now, when drying grains using a dryer, grains to be dried are loaded into the dryer one after another, but sample grains are extracted at regular intervals from the grains being loaded, and their moisture values are calculated based on the moisture content. Measured by sensor 1. The measurement results are added by the arithmetic circuit 4, and an average value is calculated by the arithmetic circuit 7, and the average moisture value is displayed on the moisture indicator 8. Furthermore, the standard deviation is calculated by 11, and this and the average moisture value calculated by the average moisture value calculation circuit are sent to the comparison circuit 12 for calculation comparison. Since the moisture content measurement using the water molecule sample 1 is carried out many times during the drying process, the moisture content of the dried grains may vary depending on the storage bag, etc. It is possible to determine the accurate initial moisture value and standard deviation of the moisture content of the whole grain to be dried.Therefore, using this accurate initial moisture value and standard deviation, it is possible not only to correctly set the drying time, etc. The drying loss rate with respect to moisture can also be set correctly taking into account moisture unevenness, and drying discount 1r can be performed accurately without causing shell cracks, etc.Moreover, even during circulation drying, moisture can be measured multiple times in the same way as above. The average moisture value and standard deviation can be obtained by using these values, and the control at the initial stage of drying can be corrected and the control can be changed to a more accurate one.
