Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is a method for finishing and drying a portion of each grain brought in by individuals and consignees to a constant moisture value under the same drying conditions in a communal drying facility. At the very least, the present invention relates to a sample grain dryer that can accurately allocate producer sales proceeds according to the share of grain brought in.

Conventional technology Conventionally, in a communal drying facility, a portion of each grain brought in by individuals and consignees was finished and dried to a constant moisture level under the same drying conditions, and the grains brought in were divided into portions of the grain brought in. A sample grain dryer is used to allocate producer sales proceeds accordingly;
As a representative example, before this application was filed, for example,
Those described in JP-A No. 56-124883 and JP-A-56-146976 are known. and,
The known sample grain dryer described in the first part above is
A heat generator is housed inside one side of the dryer frame, and the inside of the other side is divided into an upper air passage connected to the heat generator with a drying shelf installed as a border, and a lower air passage equipped with a suction exhaust fan on one side. The storage containers that are partitioned and inserted into and inserted into the dryer frame so that they can be inserted and removed freely through the opening window opened on the front side of the dryer frame are placed in parallel on the drying rack, and one or more drying boxes containing grains are taken out from the storage container. In addition, the sample grain dryer in the latter stage does not use the storage container in the former stage, and the drying box is formed with both side walls and the bottom wall in the same shape, and the front side of the dryer frame is The drying boxes are arranged side by side on a drying shelf so that they can be freely put in and taken out from an opening window opened on the drying rack,
The hot air generated in the heat generator is circulated from the upper air passage through the drying box to the lower air passage by the negative pressure action of the suction exhaust fan, thereby quickly drying the grains stored in the drying box. When the drying box is turned over, hot air can be blocked from flowing inside the drying box, and the state of the blocking can be confirmed from the outside.

Problems to be Solved by the Invention Incidentally, in all of the above-mentioned known sample grain dryers, during the operation in which grains are stored in a storage container or a drying box and dried by the circulation action of hot air, In this system, the hot air obtained by one heat generator was distributed to multiple storage containers or drying boxes at the same time, so it was necessary to distribute the hot air of uniform temperature and air volume to each of them. The grains stored in the storage containers or drying boxes cannot be uniformly sprayed, and uneven temperature and air volume are likely to occur, resulting in differences in the drying speed in each storage container or drying box. As a result, the drying end times are different, and some storage containers or drying boxes are dried quickly while others are dried slowly. A problem arose that could not be resolved.

Therefore, the present invention aims to distribute all of the sample grains housed in a plurality of sample boxes that are inserted into and removed from the main body of the dryer using the distribution action of drying air generated by a dedicated hot air generator. When the sample box is inserted into the main body of the dryer, the moisture measuring section detects the moisture content of the moisture sensor inserted into the sample grain storage chamber to ensure accurate and uniform drying so that the final moisture value is always reached. In order to prevent, as much as possible, a part of the sample grain stored in the sample grain storage chamber from leaking into the dryer main body from the moisture sensor insertion part when the sample box is inserted into and removed from the moisture sensor. Even if a part of the sample grain leaks out from one insertion part, the spilled sample grain is stored in the spilled sample grain storage chamber located next to the sample grain storage chamber to ensure that no spilled sample grain is contained. This eliminates all leakage into the dryer body, improves drying performance, and eliminates the need to clean the inside of the dryer body by eliminating sample grain leakage even when a moisture sensor is used. The above problem has been solved by providing a sample grain dryer that can be used.

Means for Solving the Problem Therefore, the technical problem of the present invention is to solve the problem by controlling the distribution of dry air obtained by a dedicated hot air generator and the moisture sensor to move sample grains housed in a plurality of sample boxes. The purpose is to accurately dry the sample grain to a predetermined moisture value by the detection action, and also to completely prevent a part of the sample grain from leaking from the sample box into the main body of the dryer even when a moisture sensor is used.

In order to solve this technical problem, the structure of the invention described in item 1 is applied to a plurality of sample grain storage chambers each having a sample grain storage chamber through which drying air obtained by a dedicated hot air generator can freely flow. The box is inserted into the dryer main body so that it can be inserted and removed freely, and when the sample box is inserted into the dryer main body at the rear of each of the sample boxes mentioned above, the waterside measurement section is inserted through the insertion part provided on the rear wall of the sample box. A sample grain dryer characterized in that a moisture sensor is disposed to be inserted into a sample grain storage chamber, and the insertion portion is closed by a pair of leak prevention bodies attached to a sample box so that their free ends are overlapped with each other. None, or the configuration of the invention described in item 2 is made up of a plurality of chambers whose interiors are divided into a sample grain storage chamber and a spilled sample grain storage chamber through which drying air obtained by a dedicated hot air generator can freely circulate. The sample box is fitted into the dryer main body so that it can be inserted and removed freely, and at the rear of each of the above sample boxes, when the sample box is inserted into the dryer main body, a moisture measuring section is installed on the back wall of the spilled paddy storage chamber. A moisture sensor is arranged to be inserted into the sample grain storage chamber through an insertion portion provided on the rear wall of the sample grain storage chamber, and the free ends of the insertion portions of the sample grain storage chamber overlap each other. The sample grain dryer is characterized in that the sample box is closed by a pair of leakage prevention bodies attached to the sample box.

Effect The above technical means acts as follows (see drawing).

Now, some of the multiple types of grain brought in by individuals and consignees are dried to a certain finished moisture value under the same drying conditions, and the producer sales price is calculated according to the grain ownership. When trying to obtain sample grains for accurate allocation, first extract some of the different types of grains brought in by individuals and consignees, use this as sample grains, and use this as sample grains. A plurality of sample boxes 3... are accommodated in a sample grain storage chamber 7 provided therein, and then these sample boxes 3... are inserted into the dryer main body 1 from the front side of the dryer main body 1 and placed thereon. .

Then, the multiple sample boxes 3 inserted and placed...
... are set in such a state that drying air generated by a dedicated hot air generator 19 ... is freely distributed in the sample grain storage chamber 7, and the same number of sample boxes 3 as the number of sample boxes 3 are stored in the dryer main body 1 in advance. Moisture sensor 11 arranged
The moisture measuring section 12 is inserted into the sample grain storage chamber 7 through the insertion sections 13 and 14 of the rear walls 9 and 10 provided in two stages on the rear side of the sample box 3.

Therefore, each hot air generator 19 is operated,
The generated drying air is passed through the sample grain storage chamber 7 to dry the sample grains contained therein. When the moisture sensor 11 detects that the sample grain has reached a predetermined finished moisture value (for example, 14.5%) through the drying process, the operation of the hot air generator 19 is stopped based on this detection signal, and the drying process is completed. finish.

Therefore, even if the initial moisture values of sample grains housed in a plurality of sample boxes 3 are different, the detected moisture values of the respective moisture sensors 11 are selected to be the same, for example, 14.5%. As long as the temperature of the drying air is controlled, it is possible to dry each sample grain sequentially and uniformly to a predetermined final finished moisture value without causing uneven drying by the distribution action of the drying air. It is possible to eliminate unevenness and unevenness in air volume.

Then, the sample grains dried to a predetermined finished moisture value are taken out from the dryer main body 1 by pulling out the sample box 3, and may be supplied one after another to the next self-testing machine.

By the way, when the sample box 3 containing the sample grains is inserted into and removed from the dryer main body 1 as described above, the moisture measuring part 12 of the moisture sensor 11 installed in advance is detected by the spilled sample grains. Since it is inserted into the sample grain storage chamber 7 through the insertion portions 13 and 14 provided on the rear wall 10 of the chamber 8 and the rear wall 9 of the sample grain storage chamber 7, respectively, the sample box 3 is inserted and removed repeatedly. A portion of the sample grains contained therein tends to leak into the dryer main body 1 through the insertion portions 13 and 14.

However, the insertion part 13 provided in the rear part 9 of the sample grain storage chamber 7 has its proximal end closed by a pair of leak prevention bodies 15, 15 attached to the sample box 3 so that the free ends overlap each other. Therefore, no matter how the sample box 3 is inserted or removed, the sample grains are blocked by the leak prevention bodies 15, 15, and leakage is prevented as much as possible. In addition, even if a part of the sample grain leaks out from the insertion part 13, since the spilled sample storage chamber 8 is provided next to the sample grain storage chamber 7, the spilled sample will be removed. The grain is reliably stored in the spilled sample grain storage chamber 8, and is prevented from leaking and falling into the dryer main body 1,
All sample grains can be fed to the next self-testing machine.

Embodiment The configuration of a sample grain dryer according to the present invention will be described with reference to a preferred embodiment shown in the accompanying drawings.

In the drawings, reference numeral 1 denotes the dryer body of the sample grain dryer, and the dryer body 1 has a hollow interior.
Adjacent to one side is a control room 2 housing various control devices. On the front wall side of the dryer main body 1, a plurality of loading/unloading windows 4 are opened at equal intervals over a plurality of stages for allowing the sample box 3 to be freely inserted into and removed from the dryer main body 1. At the same time, an outside air intake window 5 is provided on the rear wall side. As shown in FIGS. 4 to 6, the sample box 3 described above is
The top surface is open, the bottom surface is closed with a wall board 6 that allows ventilation, and the other surface is surrounded by blind walls, and the entire sample box 3 is formed into a rectangular cube box shape, and the inside of the sample box 3 is used to store sample grains. It is divided into a chamber 7 and a spill sample grain chamber 8. The rear wall 9 of the sample grain storage chamber 7 and the rear wall 10 of the spilled sample grain storage chamber 8 are provided with insertion sections 13 and 14, respectively, into which a moisture measuring section 12 of a moisture sensor 11, which will be described later, is inserted.
The proximal end of one of the insertion sections 13 is closed by a pair of leak prevention bodies 15, 15 made of an elastic material and attached to the rear wall 9 so that the free ends overlap with each other. In addition, if the other insertion portion 14 is also closed with a suitable leakage prevention body 16 made of the same leakage prevention body as described above or a brush, etc., the grains stored in the sample grain storage chamber 7 can be removed when the sample box 3 is inserted or taken out. This prevents the sample grains from leaking out of the insertion section 13, and even if some of the sample grains should leak out of the insertion section 13, the spilled sample grains can be stored in the adjacent spilled sample grains. The sample grains are housed in the chamber 8 to prevent them from leaking and being deposited inside the dryer main body 1.

Inlet/outlet windows 4 opened in parallel over multiple stages
Inside the dryer main body 1 at a position facing . The boxes 3... are placed opposite each other at intervals that allow them to be inserted and removed freely, and the walls of the ventilation housing 17 and suction/exhaust housing 18 on the side facing the sample box 3 are formed in an open shape. ing. A hot air generator 19 formed by incorporating a blower 20 and a heater 21 inside is connected to one side of each of the air blower casings 17.
The intake ports 22 of 9 are respectively opened in the dryer main body 1 to cause the generated drying air to flow from the ventilation housing 17 through the sample grain storage chamber 7 to the suction and exhaust housing 18 to finish the stored sample grains to a predetermined finish. Dry to moisture level.

A moisture sensor 11 is installed in each sample box 3 to automatically stop the operation of the hot air generator 19 when the sample grain reaches a predetermined final moisture value (for example, 14.5%) due to the distribution of drying air. The moisture measuring part 12 is fixed inside the dryer main body 1 on the rear side of ... and extends from the moisture sensor 11 toward the sample box 3 side. It is formed in such a length that it is located within the sample grain storage chamber 7.

Each suction/exhaust case 1 installed horizontally over multiple stages
8. On one side of the suction/exhaust fan 23... is provided, and on the discharge side of the suction/exhaust fan 23..., there is a single exhaust duct whose exhaust part is located outside the dryer main body 1. 24 so that the exhaust air after being used for drying is concentratedly exhausted outside the dryer main body 1.

Therefore, according to the sample grain drying according to the present invention,
Since the drying air was generated by the same number of hot air generators 19 as the sample boxes 3, the temperature and air volume of the drying air were always uniform, and the sample grain was heated to a predetermined finished moisture value without uneven temperature or air volume. The sample box 3 can be dried in the dryer body 1.
It goes without saying that even if the sample grains stored in the sample grain storage chamber 7 are operated repeatedly so that they can be freely inserted and removed from the sample grain storage chamber 7, it can be prevented as much as possible from leaking out from the insertion section 13. Even if a part of the sample grain leaks out, the spilled sample grain is stored in the spilled sample grain storage chamber 8 provided next to the sample grain storage chamber 7, so that it does not fall into the dryer main body 1. In addition to being able to reliably prevent this, if the dried sample grains are not taken out from the dryer body 1 even after drying is completed, the cold air flowing through the sample grain storage chamber 7 due to the suction action of the suction exhaust fan 23 will By allowing the product to cool slowly, it is possible to prevent skin chafing during self-inspection work.

Effects of the Invention In short, since the present invention has the above-described configuration, even when sample grain is dried using a plurality of sample boxes 3, drying air with uniform temperature and air volume can be used. The multiple sample boxes 3... When ... is inserted into the dryer main body 1, the moisture measuring part 12 of the moisture sensor 11
Even if the operation of positioning the sample grain in the sample grain storage chamber 7 through the holes 3 and 14 is repeated, the insertion portion 13 is closed by the pair of leak prevention bodies 15 and 15, so that accidental leakage is prevented as much as possible. In addition, even if a part of the sample grain leaks from the insertion part 13, the spilled sample grain can be stored in the spilled sample grain storage chamber 8 provided next to the sample grain storage chamber 7. This ensures that no part of the sample grains leaks out and accumulates inside the dryer body 1, and not only allows all the sample grains to be collected, but also eliminates the need to clean the inside of the dryer body 1. This has the effect of preventing the occurrence of harmful accidents and always achieving sanitary and efficient drying work.
