Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a grain drying method in which the moisture value of the grain to be dried that is being loaded into a dryer is measured many times and drying is controlled based on the initial moisture value obtained by averaging the measured moisture values. Regarding.

Conventionally, when drying a tI material using a dryer, or
For example, Japanese Patent Application Laid-open No. 150475/1982 or "Suction dryer 151B+, 1" published by the applicant in 1982
As described in page 4 of the instruction manual for Model 81B4, after loading a predetermined amount of grain to be dried into the dryer, sample grains are extracted from the loaded grains to be dried (2). After determining the moisture content at 71111 and determining the moisture value at the start of drying, that is, the initial moisture value, this initial moisture value was used to perform drying control such as setting the drying time. The method of taking out the amount and determining the moisture value of 471+1 is described in Japanese Patent Publication No. 16305/1983 and was known before the filing of this application.

By the way, in the method of measuring the initial moisture value in the conventional dryer described above, a very small amount of the moisture of the sample grain is
By adding, the cloth stuck in the dryer *f#4
Although this is the initial moisture value of the whole R product, the moisture value of the grain to be dried that is loaded into the dryer varies, and in particular, the moisture value varies greatly depending on the storage bag, so the sample grain is extracted after loading is completed. Even if moisture 1@wo is measured, it is not possible to obtain an accurate initial moisture value.For this reason, conventional methods do not allow drying of grains to be properly automated without under-drying or over-drying. It was difficult to dry.

Therefore, in order to eliminate the drawbacks of the conventional methods as described above, the present invention accurately measures the initial moisture value of the entire grain to be dried loaded in a dryer, and uses this to ensure proper drying control at all times. The purpose of this invention is to obtain a method for drying d-products that can be carried out.

In view of the above, in order to achieve the above object, the present invention includes a method in which sample grains are extracted multiple times from grains to be dried that are being put in a dryer, and the moisture content of each of these extracted sample forged grains is measured. At the same time, the average value is calculated to determine the initial moisture value of the grain to be dried, and this initial moisture value is used to perform drying control. According to this method, it is possible to accurately determine the average initial moisture value of the entire dried grain loaded in the dryer, even if the moisture value of the dried grain loaded in the dryer varies greatly depending on the storage bag, etc. Then, using this accurately determined initial moisture content of 1 liter, drying can be controlled so that a high-quality dried product can always be obtained without causing cracking of the grain to be dried or causing insufficient dryness or overdrying. It has the effect that it can.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an apparatus for carrying out the grain drying method according to the present invention will be described below as illustrated in the drawings.

1 is a moisture sensor; 2 is a measurement drive circuit; the moisture sensor 1 receives a command signal from the measurement drive circuit 2, extracts a sample grain from the grain to be dried that is being loaded into a dryer; It is crushed to determine its air resistance.

Reference numeral 3 denotes a moisture value/voltage conversion path, and the moisture value/vehicle pressure conversion circuit 3 receives a signal from the moisture sensor 1 and sends out a heavy pressure output signal corresponding to the moisture content of the sample grain. 4 is operation Ic
IIJ path, the arithmetic circuit 4 receives a signal obtained by converting the output of the moisture value voltage conversion circuit 3 into a digital signal by the A-D conversion circuit 5, and sequentially adds the moisture values measured by the moisture sensor 1. do. It performs calculations. 6 is a measurement number counter that counts the number of operations of the constant drive circuit 2; T is an arithmetic circuit; The average moisture value is calculated by dividing by a fixed number of times. Then, the average moisture value is displayed on the moisture display 8 based on the output signal from the arithmetic circuit T.

Further, the drying automatic Φ1 motor control is performed by the output signal of the arithmetic circuit 1.

9-digit timer; 10 is a measurement command circuit; the measurement command circuit 10 receives a time signal from the timer 9;
The circuit 2 sends a signal to drive the pivot circuit 2 at fixed time intervals.The above-mentioned interval drive circuit 2 can also be operated by a manual switch.

Next, its effect will be explained.

Now, when drying grains using a dryer, the grains to be dried are loaded into the dryer one after another, but a sample i is extracted from the grains being loaded at regular intervals, and the moisture plane or moisture sensor 1 is extracted from the grains being loaded. 1ll11 is added by. Then, the determined result is multiplied by the circuit 4, and the average value is calculated by the circuit T, and the average moisture value is displayed on the water table 8. Moisture sensor 1 above
Since the moisture content is measured many times during the drying process, the average value of the whole drying grains can be calculated even if the moisture content varies depending on the storage bag. Therefore, it is possible to determine a more accurate initial moisture value of the grain to be dried.Therefore, it is possible to use this accurate initial moisture value to set the drying time, etc. correctly. The grain size can be set correctly, and drying control such as accurate drying loss rate and grain temperature control of the grain to be dried can be carried out accurately.In addition, moisture measurement can be performed automatically at fixed intervals. , the −11 constant command χ may be manually performed for each storage bag of dried grains to be loaded.
In this case as well, the average moisture value can be obtained in the same manner as above.
