置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention allows harvested paddy with a high moisture content to be dried slowly without causing any rotting or deterioration phenomena, so that it can withstand long-term storage, and also allows paddy that has been left to stand still to be dried. The present invention relates to a storage drying device that can quickly and accurately discharge air using fresh air.
収穫した高含水率の籾を仕上がり水分まで連続的に或は
断続的に乾燥する所謂一段乾燥方式は循環乾燥方式或は
テンパリング乾燥方式としてよく知られている。The so-called one-stage drying method in which harvested paddy with a high moisture content is continuously or intermittently dried to the finished moisture content is well known as a circulation drying method or a tempering drying method.
そして上記の乾燥方式によれば仕様書に示されている1
日当りの最大処理量が持ち込まれた時には籾を速かに乾

。And according to the above drying method, 1
When the maximum amount of paddy processed per day is brought in, the paddy can be quickly dried, but once the amount of high moisture raw paddy that exceeds the maximum amount processed per day is brought in, the amount of raw paddy that exceeds the fixed amount will be stored. It is also well known that if the method is not used properly, it will generate heat, deteriorate in quality within half a day, and cause discoloration and peeling.
一般に収穫機等によって収穫された生籾は略25%〜2
75位の含有水分を保有しており、この様な高水分の生
籾を変質、着色なしに乾燥させたり或は貯蔵しておくた

に高温多湿でない限り常温の付近で1ヵ月近く貯留する
ことができることは実験によって立証されている。Generally, raw paddy harvested by harvesting machines etc. is approximately 25% to 2%.
It has a moisture content of 75%, and in order to dry or store such high moisture raw rice without deterioration or coloring, it is necessary to dry the high moisture raw rice in an appropriate pre-dryer. Approximately 18
It has been proven through experiments that if it is dried down to about 1.5%, it can be stored for about a month at room temperature even if it is deposited without ventilation, unless it is particularly hot and humid.
そこで近年能率的な収穫機により一時に大量に収穫され
た生籾が乾燥施設に持ち込まれた場合にあっても変質や
着色現象を起さず、貯留しながら乾燥作業を営ませる目
的をもった貯蔵乾燥方式が注目されて来た。Therefore, even if raw paddy, which has been harvested in large quantities at one time using efficient harvesting machines in recent years, is brought to a drying facility, it does not cause any deterioration or discoloration, and the purpose is to allow the drying process to be carried out while it is stored. Storage and drying methods have been attracting attention.
上記の貯蔵乾燥方式は一般に収穫した生籾をグレン、サ
イロ又はビン内に投入し、これに原則として常温の空気
を送って仕上り水分に乾減するまで静置式の通風乾燥を
行い、その後は籾をそのままビン内に貯蔵して置くこと
を建前としているものである。The storage drying method described above generally involves putting the harvested raw paddy into a grain, silo, or bin, and, in principle, blowing room-temperature air through it and allowing it to air dry in a stationary manner until the finished moisture is reduced.After that, the paddy is The idea is to store it as is in the bottle.
従って上述の乾燥施設を採用して高水分の生籾を乾燥せ
しめた際には乾燥速度が緩慢で厚積すると1〜2ヵ月を
要し甚だ不能率となる許りか、籾は時間の経過とともに
ゆっくりと排気側に及ぶので静置式通風乾燥の欠点であ
る「むら乾燥」を起すことになる。Therefore, when drying high-moisture raw paddy using the above-mentioned drying facility, the drying speed is slow and it takes 1 to 2 months if the paddy is piled up thickly, resulting in a severe failure rate. Since it slowly reaches the exhaust side, it causes "uneven drying" which is a drawback of stationary ventilation drying.

質、着色現象も起さず貯蔵乾燥せしめることに成功した
ものである。Therefore, in order to improve the drying efficiency, the present inventor first dried the harvested raw paddy with high moisture content using one or more pre-dryers to quickly reduce the drying content to approximately 18%. Then, if the reduced paddy is dried using one or more finishing dryers while slowly accumulating the finished moisture, it is possible to not only improve drying efficiency but also perform appropriate rotation. "Uneven dryness"
As a result, even if a large amount of raw rice is brought to a drying facility at once, it can be stored and dried without causing deterioration or discoloration.
