Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for storing and drying cereals. 2. Description of the Related Art Conventionally, so-called storage bins for receiving received grains have a drying and ventilation function for the purpose of temporary storage for preventing stuffiness due to moisture. Separate silos need to be installed, and the storage silos thereafter. For this reason, in large-scale dry preparation and storage facilities, construction costs increase, and reduction of this is required. SUMMARY OF THE INVENTION The present invention seeks to solve the above-mentioned drawbacks, and is intended to solve the above-mentioned drawbacks.
Are arranged to supply drying air to the bottles 11, and each of the bottles is provided with a stirrer 21, 21 so that the grains supplied sequentially are dried or dried. Cumulative mixed dry that mixes with cereals and dries slowly
In 燥方method, the consignee the amount of grain to meet in this before facility operations know the early paddy sliding shipments in the grain consignee of the period
As drying is mainly applied to multiple bottles with thin layers, drying proceeds
And grouped into bins 11 of a number smaller than the plurality of bins
And continue drying, and add the dried grain to any bottle
Advance and stored collectively in 1, sequentially rice sliding ship short storage <br/> grain within the bin 11, consignee grains exceeding the early paddy sliding shipments to finish the water of the accumulated mixture dried scheduled After reaching, dry grain storage method for long term storage. [0004] In facilities that ship hulling during the receiving period, prior to the operation of the facility, the amount of early hulling during the period of receiving the grain is known, and the corresponding receiving amount is a thin layer, mainly of drying. Grain filling and drying of paddy to be shipped at the initial stage of receipt,
At this time, dry rice is secured by using unused drying bottles to the maximum extent. As the drying progresses, the number of bottles
Assemble in a new bottle and continue drying. The dried grain is collected in an arbitrary bin 11 and stored ,
Correspond to shipment. Subsequent received grains are sequentially deposited at a flow rate that can maintain the quality of the grains until the bottle capacity is full, deposited, mixed and dried, and stored as they are after drying. [0005] Conventionally, the number of bins 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 more than the shipping amount. Expenses were high. In addition, the so-called cumulative mixing drying method cannot be shipped at an early stage, and thus requires a dryer having a capacity corresponding to the shipping amount. However, the operation method of the present invention and
The number of empty bins at the initial stage of receiving cargo.
For a short time in a thin layer,
Allow continuous or finished dry storage.
And without waiting for the drying finish by stirring and mixing drying,
To allow shipment of early rice, tighten if required the finishing dryer, to reduce the construction cost. An embodiment of the present invention will be described with reference to the drawings. The receiving place 2 including the receiving hoppers 1, 1,... Is separated from other main equipment groups so as to form a passage on both sides of the receiving hoppers 1, 1,. . [0007] A roughing machine 3 and a receiving and weighing machine 4 for receiving and weighing grains are connected to the receiving hopper 1 via a transport mechanism.
These are installed close to each other together with a screening machine 5 and a hulling plant 6 for receiving and drying the dried grains.
It is configured in the same building 10 as the independent inspection room 8, the product storage 9, and the like. Bin 1 for storage and drying in series with the building 10
1, 11,... Are arranged. In this embodiment, one 50 t bottle is divided into two series of left and right × 10 bins, and the left and right houses 12a, 12
b, each having a total of 40 bins. [0008] As shown in FIG.
A rectangular bottle is used, and the outer wall 11a is made of glass wool or the like as a heat insulating material.
1b and 11c use a normal wall material. The bottom of the bottle 11 is in the form of a flat sweep floor 13, and below it forms a ventilation space 14. On the upper side of the building 12 of the bin 11, there are provided conveyors 15, 15 in the form of a flight conveyor in parallel, and the space above the bin in which these conveyors 15 are disposed forms spaces in the center and left and right in cross section. Sealing bulkheads 16 and 16 are provided by a heat insulating material, and a floor material 18 is stretched in a central compartment 17 formed thereby so as to coincide with the upper end surface of the bottle 11. The compartment 17 is used for inspection. It is a configuration that can be used as a passage.
The sealing bulkheads 16, 16 are provided with insertion chutes 19, 19,. Reference numeral 20 denotes a dust exhaust fan. Each of the bottles 11, 11,... Is provided with two stirring screws 21, 21, respectively. These screws 21 and 21 are examples of a stirrer, and are provided with drive motors 22 and 22, respectively, and the 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 bin 11. This support frame 2
It is configured to reciprocate while keeping the left and right screw intervals in the direction along 3, and the entire surface can be agitated while moving the square bin in a zigzag manner by dividing it into left and right parts (Fig. 5 (a), (b)). And The number of the stirring screws 21 and 21 may be one for each bin. For example, as shown in FIG. 6, each side is divided into a plurality of sections, and the corners are formed by zigzag lines drawn while connecting points A to P in order. It is good also as composition which can be stirred over a part. 25 and 25 are discharge conveyors for discharge and rotation, which are in the form of a belt conveyor, and are provided for each system in a discharge chamber 22 provided between the left and right ventilation spaces 14 and 14. A blower room 26 is provided so as to be connected to the bins 11 and the houses 12a and 12b, and blowers 27 are connected to the entrance of the ventilation space 14 for each system. 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 includes an operation control unit, and includes an operation control mechanism for each unit and a setting input mechanism. For example, the bottles 11, 11,.
In, the information from the receiving and weighing machine 4 is obtained and each bin 11
It is provided such that the amount of insertion can be set arbitrarily by the supply time or the amount of insertion. In these bottles 11, a form in which the filling amount is made into a thin layer and mainly made to dry, or a form in which drying progresses to mix and agitate a grain that has reached or approached the finish moisture and a new received grain to promote drying, In addition, it is configured to be able to arbitrarily set and execute a form in which short-term storage or long-term storage and storage of dried finished grain until hulling shipment is performed. The form of drying, storage / storage, and hulling after receiving the goods and the processing amount thereof will be described below. Figure 3 shows the amount of paddy received,
Grain processing weight indicating the relationship between the amount of dry finishing, the amount of hulling shipment, etc.
It is an elapsed days relationship graph. In the early stage of receiving the goods, it is possible to carry out the hulling at an early stage as a drying-based bin filling, and thereafter, transfer to the above-mentioned cumulative mixing and drying, where the raw unhulled goods are mixed with the dried grains and dried, and the required amount of hulling is shipped The final dried grain is stored. Average received quantity 237 t / day, hulling shipment quantity 36
t / day, the received water content is 24% and the finished water content is 16% or less. The operation will be described below with reference to FIGS. Since early shipment of hulling is required, 237t of the first day's unloading is distributed to 20 bins and spread into thin layers, and drying starts at a high drying loss rate of 0.25% / hour. On the second day, the remaining 18 bins are left with one or two rotation bins, and the remaining 18 bins are padded with a thin layer of paddy paddy. The drying loss rate at this time is 0.15%
/ Time and slightly decrease. On the third day, the first day,
On the second day, the number of bottles is reduced to 12 for each paddy, but the batch processing is continued. The new paddy is padded into 14 bottles and dried. Here, the paddy on the first day's receipt is 16% or less, and finishes drying. [0015] The paddy that has been received on the first day has a dried finish, and is supplied for shipping. Batch processing will continue, including new unloading paddy. Use 9 bins for receiving paddy on the second day, 10 bins for 3 days, and 14 bins for receiving on the day. Four bins are used for storage of the dried paddy after hulling. On the fifth day, no cargo is received (assuming a clear sky rate of 70%). The hulling shipment continues, and the water value of the paddy paddy in each bin decreases. 2nd day unloading paddy (9 bottles;
Except during the finish drying process), the whole, including the newly received paddy, 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 second day, the received paddy is dried and stored. The new paddy paddy is mixed as above (32 bins) and gradually dried. Thereafter, the filling is continued in the same manner until 12 days, and the mixing and drying are continued thereafter. On the 14th day, since the amount of stored paddy is small and it is not possible to handle hulling shipment, the drying is promoted by switching the paddy in one predetermined bin to a thin layer of about 3 bins. In this way, it corresponds to the hulling shipment, and thereafter, it is dried and finished while gradually cutting and thinning similarly. From the 18th day on, only dry-finished paddy is stored. During that period, paddy will be stored as government-sold paddy. As described above, in facilities that ship hulling during the receiving period, the paddy to be shipped is dried in the initial stage of receiving, but at this time, unused dry bins are used to the maximum to secure dried paddy. Subsequent unloading paddy is deposited until the bottle capacity is full with an air volume that can maintain the quality of the paddy, and stored as it is after drying is completed. Conventionally, the number of bins has tended to be large in a configuration composed of a receiving bin that dries raw rice to a semi-dry state and a bin that temporarily stores more than the amount of shipment, resulting in a large equipment cost. In addition, the so-called cumulative mixing drying method cannot be shipped at an early stage, and thus requires a dryer having a capacity corresponding to the shipping amount. However, in the above-mentioned operation method, by adding a stirrer and a storage function to the bottle, rice can be shipped at an early stage, and a finish dryer is not required. In the above embodiment, since the bottom portion of the bottle is formed on the sweep floor, the discharge property of the grain is good and the residue is small, so that grains of different varieties and grades can be filled in each bin. Although the bin is formed with a flat sweep floor, an inclined floor plate as disclosed in Japanese Patent Application Laid-Open No. 59-183282 may be formed.
