[Advantages and Effects of the Invention] In a facility where hulls are shipped during the receiving period, the rice that is to be shipped is dried at the initial stage of receiving the goods. To do. Subsequent load of paddy will be accumulated until the bottle capacity is full with an amount of air that can maintain the quality of the paddy, and stored as it is after drying.

Conventionally, the number of bins tends to increase in the form of a bin for drying raw rice to a semi-dry state and a bin for temporarily storing a larger amount than the shipping amount, resulting in a large equipment cost. Was there. Further, since the so-called cumulative mixing drying method cannot be shipped at an early stage, a dryer having a capacity commensurate with the shipping amount is required. However, in the above operation method, by adding the stirring device and the storage function to the bottle, it becomes possible to ship the rice at an early stage, the finishing dryer is not required, and the above-mentioned drawbacks are eliminated.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. The cargo receiving field 2 including the cargo receiving hoppers 1, 1 ... Is configured separately from other main equipment groups so as to form passages on both sides of the cargo receiving hoppers 1, 1 ... so that the transport truck can easily enter and leave. .

The rough hopper 3 and the load receiving and weighing machine 4 for receiving and weighing the grain are connected to the load receiving hopper 1 through a transport mechanism.
These are installed in close proximity to each other along with a selection machine 5 and a hulling plant 6 which receive dried grains and select them, and an operating room 7,
It is constructed in the same building 10 as the voluntary inspection room 8, product storage space 9, and the like. Storage and drying bottle 1 in series with the building 10
1, 11, ... Are arranged. In the present embodiment, one bottle of about 50 tons has two left and right series, and 10 bottles have left and right buildings 12a, 12
Each of them is accommodated in b and has a total of 40 bins.

The bins 11, 11, ... As shown in FIG.
A square bottle is used, and the outer wall 11a is made of glass wool or the like as a heat insulating material.
Normal wall materials are used for 1b and 11c. The bottom of the bottle 11 has a flat sweep floor 13 shape, and a ventilation space 14 is formed below the bottom. On the upper side of the building 12 of the bin 11, there are provided flight conveyor-type stake conveyors 15 and 15 in parallel, and the space above the bin in which these conveyors 15 are arranged forms a space in the center and left and right in cross section. A partition wall 16 for sealing is provided by a heat insulating material, and a floor material 18 is stretched in the central compartment 17 formed by this so as to match the upper end surface of the bottle 11, and the compartment 17 is for inspection. It is a structure that can be used as a passage.
The sealing partition walls 16 and 16 are provided with tension chutes 19 and 19 for the respective bins 11 and 11. 20 is a dust exhaust fan.

Two agitating screws 21, 21 are provided in each of the bottles 11, 11 ,. These screws 21 and 21 are an example of a stirring device, and drive motors 22 and 22 are separately provided, and a support frame 23 of the screws 21 and 21 reciprocates back and forth along rails 24 and 24 provided at the upper end of the bottle 11. The support frame 2
It is configured to reciprocate while maintaining the left and right screw intervals in the direction along 3, and it is possible to stir the entire surface while dividing the square bottle into left and right and moving in a zigzag shape (Figs. 5A and 5B). I am trying.

The number of the stirring screws 21 and 21 may be one for each bottle. For example, as shown in FIG. 6, each side is divided into a plurality of parts and the points A to P are sequentially connected to draw a zigzag line. It may be configured such that stirring can be carried out over all parts. Denoted at 25 and 25 are discharge conveyors for rotation and rotation, which are in the form of belt conveyors and are provided for each series in the discharge chamber 22 provided between the left and right ventilation spaces 14, 14.

A blower chamber 26 is provided in a state of being connected to the bins 11 and 11 for houses 12a and 12b, and blowers 27, 27, ... Reference numerals 28 and 28 denote heating devices, and the blower 27 can supply hot air to the ventilation space 14 by operating the heating devices. The operation room 7 is provided with an operation control section, and each section has an operation control mechanism and a setting input mechanism. For example, the bins 11, 11, ...
In the case of receiving information from the receiving and weighing machine 4,
The amount of each stake is set so that it can be arbitrarily set by the supply time or the detection of the stake. In these bottles 11, a mode in which the amount of swelling is made into a thin layer and is mainly used for drying, a mode in which the grains that have been dried or have reached the finishing moisture content or have been approaching this and agitation are mixed and stirred to promote drying, In addition, the dry finished grain can be stored and stored in a short-term storage or long-term storage until hull shipment.

The forms of the drying, storage / storage, and hulling after receiving the cargo and the amount of processing will be described below. Figure 3 shows the amount of paddy received
Grain processing weight, which shows the relationship between the amount of dry finish and the amount of hulled rice shipped −
It is an elapsed days relation graph. In the initial stage of receiving the cargo, it is possible to carry out hull shipment as a dry-loaded bottle at an early stage.After that, the raw rice from the cargo receiving is mixed with the dried grain and dried. The final dry-processed grain is to be stored.

Average load received 237t / day, hull shipment 36
t / day, moisture content of received goods is 24%, and finishing moisture content is 16% or less. The operation will be described below with reference to the above-mentioned explanatory views of the bottle utilization situation in FIGS. 3 and 4. Due to the need for early hull shipment, 23 days of first day receipt
7t is divided into 20 bottles and placed in a thin layer, 0.25%
/ Start drying at a high rate of drying. 1-2 as rotation bottles on the second day
The remaining 18 bins are thinly laid on the concealed paddy in the remaining 18 bins. The drying loss rate at this time is 0.15% / hour, which is slightly low. On the 3rd day, the number of bins on the first day and the 2nd day of the consignment are reduced to 12, respectively, but batch processing is continued. New consignment paddy is placed in 14 bins and dried. Here, the unhulled rice received on the first day is less than 16%, and the finishing drying process begins. The paddy received on the first day will be dried and will be shipped for paddy shipment. Batch processing will continue including the new paddy. 9 bins on the 2nd day, 10 bins on the 3rd day and 14 bins on the day. 4 bins are used for storage of dry-finished paddy after hulling. No cargo will be received on the 5th day (70% clear weather rate). The shipment of paddy continues, and the water content of the paddy paddy in each bottle decreases. On the second day, except for the unhulled paddy (9 bins; the finishing drying process is being performed), the entire new unloaded hull is mixed in 28 bins and gradually dried (cumulative mixed drying). At this time, the stirring screws 21 and 21 are driven to stir the paddy. On the 2nd day, the unhulled rice is dried and stored. Fresh paddy is mixed as above (32 bins) and gradually dried.

In the same manner, the swelling is continued until 12th, and the mixing and drying is continued thereafter. On the 14th day, the amount of stored paddy is small and the paddy cannot be shipped by hulling. Therefore, the paddy in a given 1 bin is switched to a thin layer of about 3 bins to promote drying. In this way, it is possible to handle shipment by hulling, and thereafter, likewise, it is gradually cut into thin layers for dry finishing. After the 18th, only dried rice will be stored and stored. During that period, it will be stored as rice sold by the government.

As described above, in the facility where hulls are shipped during the receiving period, the rice that is to be shipped is dried at the initial stage of receiving the goods. At this time, the unused dry bottle is used to the maximum extent to dry the rice. Secure. Subsequent load of paddy will be accumulated until the bottle capacity is full with an amount of air that can maintain the quality of the paddy, and stored as it is after drying. Conventionally, the number of bottles tends to increase in the form of a receiving bin for drying raw rice to a semi-dry state and a bin for temporarily storing a larger amount than the shipping amount, resulting in a large equipment cost. Further, since the so-called cumulative mixing drying method cannot be shipped at an early stage, a dryer having a capacity commensurate with the shipping amount is required.

However, in the above operating method, by adding the stirring device and the storage function to the bottle, early rice can be shipped, and the finishing dryer is not necessary. In the above-mentioned embodiment, since the bottom of the bottle is formed on the sweep floor, the dischargeability of the grain is good and the amount of the grain remaining is small.

Although the bottle is formed of a flat sweep floor, it is also possible to form an inclined floor plate as shown in Japanese Patent Laid-Open No. 59-183282.
