Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention is directed to drying and adjusting a portion of sample grains brought in individually or by each person at a communal drying and conditioning facility to a desired finished moisture content. The present invention relates to a method for drying sample grains in a drying facility and an apparatus for drying sample grains in a drying facility, in which the sample grains are quickly finished and dried to a desired value, and the sales proceeds to producers are accurately distributed according to the share of the grains brought in.

``Conventional technology'' Previously, in a joint drying and conditioning facility, it was possible to dry a wide variety of sample grains brought in at the same time. A grain sample drying device that facilitates the treatment of dry exhaust air containing dust discharged from the device is known as described in Japanese Patent Publication No. 63-23471 before the present application, the contents of which are described in Fig. 2. explain.

That is, a rectangular drying frame 1 extending in the horizontal direction is partitioned into an upper air passage 3 and a lower air passage 4 by horizontally placing a drying rack 2 therein. A plurality of storage containers 7 are provided which can be freely accessed and removed through a plurality of opening windows 6 provided in the front side wall 5, and each of these storage containers 57 is provided with a bottom wall 9 having a ventilation hole 8. A plurality of boxes 10 are removably placed on top of each other, and the upper air passage 3 communicates with the hot air generator 1) provided on one side of the machine frame 1 in the lateral direction, and the lower air passage 4Fi communicates with the other side of the machine frame 1 in the lateral direction. The air heated by the hot air generator 1) is communicated with the provided exhaust fan 12, and the air heated by the hot air generator 1) is transferred from the upper air passage 3 to each drying box 10 by the suction force generated by the rotation of the exhaust fan 12.・The sample grains are dried by flowing through them and being discharged from the lower air passage 4 to the outside of the machine frame 1.

[Problem to be solved by the invention] By the way, in the conventional grain sample drying apparatus of this type,
Not only do the initial moisture values of the grains brought in by individuals or people differ, but the time they are brought in also varies, so the sample grains of each grain brought in are finished and dried so that they have the same moisture value. This may require the operator to constantly monitor the drying state, but the drying time (approximately 24 hours) may be due to the fact that the sample grains are dried using hot drying air.
(Not only that, but if there are many tube openings, the number of storage containers will naturally be large.As a result, the grain sample drying device will also inevitably be large, requiring a large installation area, etc.). There was a problem.

The present invention has been made in view of the above-mentioned problems of the conventional technology, and its purpose is to calculate the average moisture content of grains fed into four receiving weighing machines and the moisture content extracted from the received grains. A detection signal indicating the input weight of some sample grains put into a dryer equipped with a weight measuring device is sent to the dryer control device to dry the sample grains, and the desired moisture value of the sample grains is determined by the control operation of the dryer control device. It is an object of the present invention to provide a method for drying sample grains in a drying facility and an apparatus for drying sample grains in a drying facility, which can continuously obtain sample grains that have been dried to a weight of .

Means for Solving Problem F" In order to achieve the above object, the method for drying sample grains in a drying facility according to the present invention is based on a method for drying sample grains in a drying facility. Grain is put into a dryer equipped with a weight measuring device, the weight of the feed is measured, drying is started, and the sample grain is continuously or over time controlled by a dryer control device that operates based on the measured average moisture value and the weight of the feed. The sample grains are dried until the weight reaches the desired moisture value while measuring the weight of each sample grain at A cargo receiver equipped with a moisture meter that can send moisture to the control device, and a receiver IJ
A part of the sample grains extracted from the grains put into the dryer is fed to the dryer equipped with a weight measuring device, and the average moisture value of each measured moisture value sent from the moisture meter is sent to the dryer control device. A control device that starts and stops the sample grain, measures the weight of the sample grain that has not been added, and measures the layers of the sample grain continuously or over time during the drying process so that the weight reaches the desired moisture value. This dryer is equipped with a weight measuring device that stops drying by controlling the dryer control device when the dryer reaches a certain weight.

``Function'' Now, the grains brought in by individuals or people at Tsutsuguchi are put into the receiving weighing machine one after another and their weight is measured one after another.At the same time, the moisture value of each grain put in is measured by the moisture meter. Sends a moisture value signal to the control device. Therefore, depending on the amount of grain brought in, for example, if the number of times the grain is fed into the receiving machine is six times, the number of moisture measurements by the moisture meter will be six times, and the amount of grain A will be measured six times, and the dispute is measured.

Each moisture value measured by the moisture meter is sent as a signal each time to the control device, and then the control device sends a signal of the average moisture value W, (for example, 25%) to the dryer control device. sent to.

On the other hand, a part of the grains fed into the receiving and weighing machine are extracted by the control operation of the control device, become sample grains, and are fed into a dryer equipped with a weighing device, and immediately the weight of the sample grains fi'W+
(for example 120.9) is measured and the signal is sent to the dryer controller. Therefore, drying is started by the control operation of the dryer control device, and as the drying of the sample grain progresses, the weight of the sample grain is measured continuously or over time by a weighing device, and the measured value is used to control the dryer. It is sent as a signal to the device.

By the way, in the dryer control device, there is a desired finished moisture value W= (
For example, the formula for calculating the weight wt (15%) is pre-installed, so the weight can be calculated immediately.

That is, in the method and apparatus of the present invention, the average moisture value w is 25%, the amount of sample grain fed into the dryer is 120g, the desired finished moisture content is Since the value Wfi is 15%, the weight W that gives the desired finished moisture value is as follows by bending, and it is only necessary to dry 120 g of sample grain to reduce the weight to 1059. .

Therefore, if drying is continued by the control operation of the dryer control device and drying is stopped when the weight ffiwz of the sample grain reaches 105I, the sample grain with the desired finished moisture value (for example, 15%) will be easily obtained.

Therefore, grains with different moisture values brought in at different times by individuals or by both parties can be dried to a desired finished moisture value by the same operation as described above.

"Real example" A practical example will be explained with reference to the drawings.

In FIG. 1, 101 is a receiving and weighing machine for weighing the amount of grain brought in by individual or by both parties,
The cargo receiver i@101 has an open upper surface and two upper and lower hoppers 102 and 103, each having drop ports 104 and 105 that can be opened and closed at the bottom, respectively, and are erected at appropriate intervals. . Then, on one side of the lower hopper 102, the moisture value of the received grain is measured, and the measured moisture value is transferred to the receiving weighing machine 102.
Moisture meter 10 for sending a signal to the control device 106 of 1
7 is attached. Therefore, if the number of times of weighing with the receiving weighing machine 101 is six, the number of times of moisture measurement with the moisture meter 107 will also be six, and the moisture measurement value will be sent to the control device 106 each time.

Incidentally, the amount of grain can also be measured by the receiving weighing machine 101.

106 averages a plurality of measured values sent from the moisture meter 107 to control the operation of the cargo receiving meter 31 101, and outputs the average moisture value W to the dryer control device 10.
It is a control device that can be sent as a signal to 9.

108 is a dryer equipped with a weight measuring device for finishing and drying some of the sample grains extracted from the grains loaded into the receiving machine t)elol to a desired finished moisture value (for example, 15%), The dryer 108 is equipped with a weight measuring device 1)0 for measuring the weight of sample grains fed therein continuously or over time. The measured weight W of the sample grain is sequentially sent as a signal to the dryer control device e109. The dryer control device 109 described above can control the start and stop of the dryer 108, and the control device 106
Based on the average moisture value w1 sent from the dryer 108 and the frfiW+ of the sample grains that were not put into the dryer 108, dry the sample grains until the desired finished ice content wt (for example, 15%) is reached. Control equipment to allow work to continue has not been installed.

Therefore, the drying mode control device 109 has 0O-WI. W,=W,X- 100-w2 Contains arithmetic expressions.

Therefore, the average moisture value W1...25% The weight of the sample grain fiW+...120F! When the desired finished moisture value W is set to 15%, the drying stop weight W of the sample grain becomes the above formula %, and in order to make the sample grain the desired finished moisture value 15%, the sample grain The weight of the grain is 105. ! It turns out that it is sufficient to set it to i+.

[Effects of the Invention] Since the present invention is configured as described above, it produces effects as described below.

The device that measures the average moisture content of the grains fed into the receiving weigher and the weight extracted from the received grains sends detection signals to the dryer control device, respectively, from the sample grain cans fed into the dryer. At the same time, the sample grains can be sent to the drying facility for drying, and can also be dried to a weight with a desired moisture content by the control operation of the dryer control device. By uniformly drying some sample grains to a desired finished moisture value, producers can accurately allocate sales proceeds according to their share of the grains brought in.
