Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for drying grain, and more particularly, to a method for drying grain from initial drying to storage after finishing drying by using a plurality of bins (square bottles) having a common drying air blow duct. An improved grain drying process suitable for performing.

[0002]

2. Description of the Related Art In the case of rice, for example, the harvested rice received is dried by heating to a water content of usually from 24% to 17% (this 24% is determined by the Ministry of Agriculture, Forestry and Fisheries). Is 24%, and 17%
This is because the Ministry of Agriculture, Forestry and Fisheries has set a standard for safe storage of primary storage for a short period of time, with no ventilation at 17% or less and storage within 35 days. In this specification, "semi-dry moisture"
Means a water state of 17% or less in the above sense) and is stored in the primary storage tank. The harvested rice stored first is then subjected to a final moisture drying
Finished and dried to ~ 14.5% or less, weighed after careful selection and stored in silos.

[0003] In this treatment method by thermal drying, in the thermal drying step, the moisture is dried at a stretch from 24% to 17%, and some of the harvested rice may be overdried and cracked. Moreover, the grain temperature rises due to the heating, and the quality may decrease. Japanese Patent Application Laid-Open No. 3-122484 discloses a solution to the above disadvantages of thermal drying.
The publication discloses a number of drying tanks, a number of storage bins, and a processing device such as a rice huller. The drying tank is supplied with dehumidified air dehumidified by an air conditioner to dehumidify and dry the grains carried into the drying tank. At the same time, it has been proposed to store dried cereals in storage bins, take out the cereals stored in storage bins as necessary, process them such as hulling, and then pack them and ship them. .

[0004] Although this drying method is intended to solve the disadvantages of the conventional thermal drying, in order to eliminate uneven drying in the drying tank, a replacement tank is provided separately from the drying tank, and one drying tank is used. When the dehumidifying drying process has been completed, the grains are replaced from one of the drying tanks into a rotation tank, the grains in the other drying tanks are transferred to the empty drying tank, and finally the empty drying tank is moved to the empty drying tank. The so-called rotation operation of transferring the grains in the rotation tank, that is, the well-dried grains in the lower layer and the poorly-dried grains in the upper layer are mixed, and then dehumidification and drying are performed again to obtain uniform moisture.

[0005] This processing facility requires a storage tank and a rotation tank in addition to the drying tank, which not only increases the facility cost, but also in a large facility with many drying tanks, the rotation work requires a large amount of work. The rotation capacity depends on the discharge capacity by wind from one bin, but the discharge capacity in a normal drying treatment facility is 20-30 tons per hour, and it takes 2-3 hours to empty one 50 ton bottle. Become. For example, in the case of a facility having 10 bins, only one day is required for this rotation work.

[0006] As one proposal for solving the inconvenience,
As shown in FIG. 7, a number of storage bins A (A1 to A10)
Of the storage bins A, a take-out conveyor 10 for transferring from a storage bin (for example, A1) into which grains are loaded to an empty storage bin (for example, A2), and an input elevator 1
1, a replacement device including a charging conveyor 12 and the like, rotation instruction means for sequentially designating empty storage bins as arrival bins, and instructing transfer from the storage bins into which the grain has been transported to empty storage bins, The apparatus is provided with a rotation control mechanism having an output unit for sequentially outputting operation commands. In the storage bins A (A1 to A10), drying and necessary rotation are performed, and storage until shipment is performed there. A known processing facility is known (see JP-A-5-79759).

In FIG. 7, reference numeral 1 denotes a receiving hopper for collecting grains, 2 denotes a loading / unloading machine, 4 denotes a roughing machine, and 5 denotes a weighing machine. After being weighed every 300 kg), it is charged into necessary storage bins by the charging elevator 11 and the charging conveyor 12. Grains stored after the necessary drying treatment are carried out from the take-out conveyor 10 as necessary, and are controlled from the discharge elevator 13 by the adjusting tank 6, the hulling machine 7, the rocking sorter 8, and the shipping tank. 9 is carried out of the system via a grain carrying-out section provided with the cereals 9.

This does not require the provision of a drying tank and a storage bin as in conventional facilities, and does not require a special rotation tank, which can reduce equipment costs and increase the number of workers. Each time you make a transfer,
There is an advantage that processing without drying unevenness can be performed by a simple operation without having to specify the departure and arrival bins.

[0009] However, since the treatment facility using this method moves the grains during the drying process anyway, a storage bin for rotation is necessary, and an operator is required to monitor the rotation. Need to watch the entire system. Further, when drying is performed in a high pile to increase the storage efficiency, a moisture difference may occur between the upper and lower portions, and finishing drying may be difficult. Japanese Patent Application Laid-Open No. 7-103648 discloses a further improved grain drying treatment apparatus having a large number of storage bins, which does not cause drying unevenness without rotating the grain between storage bins as shown in FIG. A grain drying apparatus capable of performing a drying process has been proposed.

[0010] In this grain drying treatment apparatus, the receiving section and the grain discharging section may be the same as those shown in FIG.
The received grain is weighed by a predetermined amount, and then is weighed from the bin input elevator E via the top conveyor TC into predetermined bins (rows A1 to A7 and rows B1 to B7) with the same thickness. A lower part of each bin row forms a supply path (dry air blowing duct) P for dehumidified air, and the supply path P is connected to a conventionally known air conditioner 20 and a blower 21 to provide dehumidified air. Is supplied to dry the grain in each bottle. Below the bin rows A1 to A7 and B1 to B7, a bottom conveyor BC is provided, and the processed grain is sent from the bottom conveyor BC to the bin input elevator E, and from the upper portion thereof, a regulating tank is provided via a switching valve. 6 and then sequentially pass through the grain discharge section to be transported outside the facility.

The above structure is almost the same as that of the processing facility described above with reference to FIG. 7, but in this processing facility, the grains to be stored in the bins (A1 to A7 and B1 to B7) are arranged at least in the vertical direction. Stirrer 100 capable of stirring
Is different from that of FIG.
In this grain drying processing apparatus, the grains in each storage bin are always subjected to at least the vertical stirring by the stirring apparatus, and without performing the so-called rotation work as in the conventional drying processing facility, the supply of the dehumidified air is performed. The desired drying treatment can be completed without causing uneven drying of the grains in the bottle in the drying process. In addition, the grains after the drying process can be stored in the bottles as they are, and idle bottles can be eliminated, resulting in a reduction in facility and maintenance costs as a whole.

[0012]

As described above, a drying processing apparatus having a storage bin provided with a stirring device has many advantages, but on the other hand, in a processing facility having a large number of bins, all of the drying processing apparatuses have an advantage. Since the bins are provided with the stirring device, the installation cost of the facility is increased, and the amount of electric power for driving the stirring device is increased, so that the operating cost of the facility must be increased.

[0013] The most efficient operation is to carry out drying treatment by ventilation in a state where grains are deposited at the same height as all the bins. In order to carry out the receiving operation, bins having different pile heights tend to be generated in the same series of drying units, and there may be a case where bins for which a safe air volume ratio cannot be ensured are generated. In addition, for this reason, drying time tends to be high piled-up drying in a small number of bottles, grain resistance at the time of blowing increases, and there is a possibility that a situation occurs in which the amount of air generated by the blower decreases and drying efficiency decreases. .

An object of the present invention is to eliminate the above-mentioned disadvantages of a drying treatment facility having a storage bin equipped with a stirring device, and more specifically, to set up and operate the grain drying treatment facility. It is an object of the present invention to provide a grain drying treatment method which can reduce both the volumetric efficiency of a bottle and the drying efficiency by air blowing while reducing both of them, and can greatly reduce the work load of an operator.

[0015]

In the grain drying method according to the present invention, a plurality of bins are basically used as a drying processing apparatus so as to share an input transfer device and a drying air blowing duct. The plurality of bottles are provided with a stirrer for stirring the grains in the bottles at least in the up-down direction, and a drying unit having no stirrer is used.

In the present invention, the received grain is put into a bin equipped with the stirring device by a feeding conveyor, where it is dried to half-dry moisture, which can be stored semi-dry while performing necessary stirring by the stirring device. Thereafter, the process of transferring the semi-dried cereal to the bottle without the stirring device using the feeding conveyor is repeated until the bottle without the stirring device becomes full. The semi-dried cereal stored in the bottle without a stirrer is semi-dry storage without ventilating until the end of receiving the cargo, and is stored as it is until shipment.

After the bottles without the stirring device are full, the loaded grains are sequentially loaded into the bins with the stirring device by the loading conveyor, and the necessary stirring is performed by the stirring device there. And drying to finish moisture. The dried grain is then stored as it is until shipment. In another embodiment of the grain drying treatment method according to the present invention, the process is repeated until the bottle without the stirrer is full in the same manner as described above, and after the bottle without the stirrer is full, The received grain is put into a bin equipped with the stirrer by a feeding carrier,
Therefore, the process of drying the semi-dried grains into a part of the bottle provided with the stirrer after drying the semi-dry grain to the semi-dry moisture that can be semi-dried and stored while performing the necessary stirring with the stirrer Repeat until is full. The expired semi-dried cereal is subjected to a process of drying it to finish moisture, and the dried cereal is stored as it is until shipment.

After a part of the bottles provided with the stirring device for stacking the grains dried to the semi-dry moisture becomes full, the remaining grain is provided by the carrier for feeding the received grains. The bottles are sequentially charged, and a process of drying to the finish moisture while performing necessary stirring by a stirrer is performed. The dried grain is stored there as it is until shipment.

In the grain drying method according to the present invention, as a treatment facility, a plurality of bottles in one drying unit are provided with a stirrer for stirring the grains in the bottles at least in the vertical direction, and Since the apparatus is configured without the above, the costs related to the installation of the stirrer can be reduced as compared with the conventional facility, and the installation cost of the entire facility is reduced. In addition, as the number of the stirring devices is small, the operation cost is reduced.

According to the grain drying treatment method of the present invention,
While using a processing facility that can be installed and operated at a low cost as described above, with a drying efficiency equivalent to or higher than when grain is dried by a processing facility equipped with a stirrer in every bottle. Thus, the grain can be dried.

That is, at the end of the receiving of the grains, the grains can be stored in all the bins (drying bins) provided with the stirrer and the bins (storage bins) having no stirrer, and the storage efficiency can be increased. In addition, although it is necessary to perform a so-called rotation operation, the operation can be performed only once from the drying bin to the receiving bin or from the drying bin to another drying bin until the end of the receiving operation. It is a movement within the area, and automatic driving becomes possible. In addition, the operation cost is reduced because the air flow loss due to the rotation and the power consumption due to the conveyance are reduced.

Further, a cumulative stirring, mixing and drying process in the drying bottle in a period from the start of receiving the cargo to a later stage of receiving the cargo, that is, a process of sequentially feeding the receiving grains and drying to the finish moisture while performing necessary stirring with a stirring device is performed. Until
Even when a plurality of types of goods are received, high-load drying can be avoided, and drying with high drying efficiency can be achieved, and both drying time and operating cost can be reduced. The present invention further has a plurality of the drying units described above, has a common receiving unit for each drying unit series, and the grains put into each drying unit series from the receiving unit are described above in the drying unit series. Also disclosed is a grain drying treatment method characterized in that the grain drying treatment method is performed until finish drying.

The stirrer 100 is arbitrary as long as it can stir the grains in the storage tank substantially uniformly in the vertical direction. For example, a stirrer as described in Japanese Patent No. 2677946 is particularly effectively used. .

Next, in the case where the grain drying treatment method according to the present invention is carried out using a grain drying treatment apparatus of the above type,
An example will be described with reference to FIGS. In this example,
The receiving form is three kinds of receiving of A, B and C, and it is assumed that there is a one-day receiving suspension day after receiving three consecutive days. Here, a case will be described in which the grain from the receiving section is thrown into the drying unit in row A via the loading elevator E and the top conveyor TC, and the drying is performed there until the drying is performed. It is clear that the same treatment can be performed in the drying unit of
Description is omitted.

On the first day, the cereal (type A—water content 24%) received in two bins (A1, A2), one third of the six bins, is evenly charged, and stirred and blown. The drying process is performed while performing (FIG. 3A). On the second day, the drying process in the two bins (A1, A2) (water content 20.5%) on the first day is continued, and two empty bins (A
3, A4) (A variety-moisture content 24)
%), And drying is performed while stirring and blowing (FIG. 3B).

On the third day, two bottles (A1, A2) on the first day
(Water content 17.5%) and 2 bottles on day 2 (A3-A
4) The drying treatment at (moisture content 20.5%) is continued, and the cereal (A type-moisture content 24%) received in two empty drying bins (A5, A6) is evenly charged. ,
The drying process is performed while stirring and blowing (FIG. 3B).
The fourth day is a day without receiving the cargo, and the 6 bottles (A1 to A6) into which the cereals are charged on the first, second, and third days continue the drying process as it is. If the receiving grain (A1, A2 bottle) on the first day has been dried to semi-dry moisture (water content of 17% or less) (to be dried to semi-dry moisture in the blast drying process of 3 to 4 days, It is normal to set the blowing conditions), the drying is stopped by shutting off the blowing air to these two bins, and if there is enough time, the grains of the A1 and A2 bins are stored in the storage bins A7 to
Move (rotate) to one of A12.

The fifth day is the fourth day of receiving the A type.
If the cereals on the first day are not transferred to the storage bins on the fourth day, the cereals on the first day (the cereals in the A1 and A2 bins) are stored in any one of the storage bins A7 to A12 (just before the start of receiving). In the example, the process moves to A12). The dried bins (A1, A2) that were emptied thereby received the grains on the 5th day (24 moisture content).
%), And drying is performed while stirring and blowing (FIG. 3d). From day 6 onwards, storage bins (A7-
Until A12) becomes full, the same operation as on the fifth day is performed on a day with a receipt and the same operation on the fourth day on a day without a receipt.

FIG. 4a shows a state where the receiving of the type A is completed and the receiving of the type B is carried out on the first day, and the storage bins A12 and A11 are filled with the type A which has been dried to semi-dry moisture. The storage bin A10 is almost full. FIG. 4B shows the state of receipt of the B type on the second day. At this time, the A type remains only in the drying bins A5 and A6. Fig. 4c shows the state of receipt of the third day of the B type, at this time, four storage bins (A9 to A9).
12) is full with A-type cereals. FIG.
d indicates the state of receipt of the B-type on the fourth day. At this point, the received amount of the B-type on the first day is already in a dry state to semi-dry moisture and has been moved to the storage bin A8 (FIG. 4).
d).

Hereinafter, the receiving of the B type is continued, and when it is completed, the receiving of the C type starts. FIG.
In this example, the receiving state of the varieties on the first day is shown. In this example, the B varieties in the middle of drying remain in the four bins of the drying bins A3 to A6, and the B varieties that have become less than semi-dry moisture are stored in the storage bin A8. , And more than half of the last storage bin, bin A7. FIG. 5B shows the state of receipt of the C-type on the second day, in which B is less than semi-dry moisture.
The varieties received the day before the last day (A3, A4) are moved to the last storage bin A7, but before the entire amount is moved, the storage bin A7 becomes full. At that time, all the storage bins (A7 to A1)
2) is full. Then, the last day of the B type, which has become less than the remaining semi-dry moisture, is still undried.
It is moved above the final goods receipt (A5, A6) where it is stirred and dried.

FIG. 5C shows the state of receipt of the C type on the third day. At this time, the B type in the drying bins A5 and A6 has less than half-dry moisture. The bins (bin A6 in this example) are put together, and the C varieties loaded into A1 to A4 are transferred so as to have a uniform thickness including the empty dry bin A5. After that, the received C type on the third day is thrown into the drying bottles A1 to A5 in a uniform thickness, and the drying process is performed while stirring and blowing.

On the fourth day of receiving the varieties of the C varieties, the received cereals are put into the drying bins A1 to A5 in a uniform thickness, and a drying process is performed while stirring and blowing (FIG. 5d). At this time, since the B type stored in the drying bin A6 has less than half-dry moisture, stirring with a stirring device is unnecessary, and the semi-dry storage is performed without ventilating until the end of receiving the cargo. After the fifth day of receiving the C type, the processing on the fourth day of the receiving is performed until the receiving of the C type is completed (or the drying bottles (A1 to A5)).
(Until is full) (FIG. 5e). This drying process in the drying bottles (A1 to A5) is referred to as cumulative stirring mixing drying process. When the grains in the drying bottles (A1 to A5) have a moisture content equal to or less than the semi-dry moisture, the operation of the stirrer is stopped, and the semi-dry storage is not performed until ventilation is completed.

Thereafter, all the bins, that is, the drying bins A1 to A6 and the storage bins A7 to A12 are dried to finish moisture while being blown as necessary, and the dried grain is left as it is at the time of shipment. Stored up to.
Hereinafter, similarly to the conventional facilities, the processed grains are sent from the bottom conveyor BC to the bin loading elevator E, and are transported from above to the regulating tank 6 via the switching valve, and then sequentially pass through the grain discharge section. It is carried outside the facility.

The above description is of a preferred embodiment of the grain drying treatment method according to the present invention, and may take many other forms. For example, some drying bottles (eg,
The above-mentioned cumulative stirring, mixing and drying process is performed simultaneously in all the drying bins A1 to A6 without taking an operation method in which the drying bin A6) in the above example performs both functions of the drying bin and the storage bin. You can also drive.
Also, what is the total number of bins in one drying unit,
The number of stirrers and the number of drying units are set as appropriate depending on the grain receiving environment of the facility, and the ones shown in the drawings are merely examples. Absent.

Furthermore, if there is room in the capacity of each bin, the state shown in FIG. 5E, that is, after all the receiving grains have been dried to semi-dry moisture, the five drying bins A1 to A5 As shown in FIG. 6, the C varieties put in the hoppers are transferred to the four dry bins A1 to A4, and empty varieties are secured to replace the C varieties with the A and B varieties.
Finish the semi-dry paddy of B varieties in a drying bottle and perform the selection work. Alternatively, it is also possible to perform rotation by a conventional method using the empty bin as a rotation bin.

[0038]

As can be seen from the above description, according to the grain drying treatment method according to the present invention, the stirring device is used at the end of receiving the cargo while using the grain drying treatment device which can be installed and operated at low cost. Grains can be stored in all of the attached bottles (drying bottles) and the bottles without it (storage bottles), and the storage efficiency can be increased. In addition, although it is necessary to perform a so-called rotation operation, the operation can be performed only once from the drying bin to the storage bin or from the drying bin to another drying bin until the end of receiving the cargo. It is a movement within the area, and automatic driving becomes possible. In addition, the operation cost is reduced because the air flow loss due to the rotation and the power consumption due to the conveyance are reduced. Furthermore, during the period from the start of receiving the cargo to the stage of cumulative stirring and mixing and drying in the drying bin in the latter stage of receiving the cargo, it is possible to avoid high-load drying even when receiving multiple varieties, resulting in drying with high drying efficiency. In addition, both drying time and operating cost can be reduced.

Further, even when a plurality of drying units are provided in parallel, it is possible to directly feed the drying units from the common receiving unit to all the drying units. As a result, labor saving in the drying process can be achieved.
