Description

【0001】
【産業上の利用分野】
この発明は、乾燥調製施設等荷受け穀物の自主検定装置に供給する前にサンプル穀物を乾燥するサンプル穀物乾燥装置に関する。
【0002】
【従来技術及び発明が解決しようとする課題】
従来、サンプル穀物乾燥装置として、例えば特開平2−157048号公報に記載の構成が公知である。この構成は、サンプル乾燥機本体機枠の正面縦横複数に形成した空間部に、サンプル穀物を収容したサンプル箱を格納し、これらサンプル箱の夫々に対応すべくヒータ及び吸引ファンを個々に構成して、必要な乾燥サンプルに対して該ヒータ及び吸引ファンを作動してサンプル乾燥する構成である。
【0003】
上記の構成では、個別にヒータを備える構成であるから、コストが上昇し、ひいてはサンプル乾燥機本体前後長さが長くなり占有面積の拡大等を余儀なくさせる。また、外気を導入してヒータ通電によって乾燥風を発生させる構成であるから、外気温度の影響を直接受け、乾燥時間が一様となり難い欠点を有する。とりわけ、外気温度が低い場合にはヒータによる加熱が不十分となりがちで乾燥温度が上昇せず、乾燥も不十分であった。
【0004】
【課題を解決するための手段】
この発明は上記に鑑み、小型で廉価なサンプル乾燥装置を実現しようとし、次の技術的手段を講じた。即ち、機枠の正面側には縦方向及び横方向に複数のサンプル箱格納空間を有し、該空間にサンプル箱に収容したサンプル穀物を所定に乾燥するサンプル穀物乾燥装置において、該乾燥装置の機枠内であって上記格納されたサンプル箱の背面側に乾燥風循環経路を形成し、該乾燥風循環経路に各サンプル箱への個別導入経路をのぞませると共に、当該個別導入経路の入り口部には乾燥風導入又は非導入に切り替える切替手段を設け、乾燥風循環経路の通気前後側をサンプル箱の背面側空間に開放したダクト部材と、ヒータ,除湿器等の乾燥風調整機器と、循環用ファンとを設け、該循環用ファンの作動によりダクト内外を循環通風する構成とする。
【0005】
【0006】
【0007】
【発明の作用及び効果】
この発明は以上の構成であるから、常時乾燥風循環経路が形成され、乾燥風が循環するものであるから、外気変動等による温度変動の影響を受け難く、もってサンプル穀物の乾燥処理時間の予測が立て易く精度向上がはかれる。また、サンプル箱を格納する格納空間毎にヒータを設ける必要がなくなり、コストダウンに寄与しうる。
【0008】
【0009】
【発明の実施の形態】
この発明の一実施例を図面に基づいて説明する。図1はサンプル乾燥から自主検定を経てサンプルを袋詰するサンプルパックまでを一連に自動化した装置の概要であり、1はサンプル乾燥機、2は自主検定装置、3はサンプルパック機、4は制御部である。
【0010】
上記のうち、サンプル乾燥機1は、サンプル収容すべきサンプル箱5,5…にサンプルを投入ないし排出するサンプル投入排出部6と、機枠の正面側に複数のサンプルを格納しうる格納空間(図例では縦10列横12列で計120口)7,7…を形成したサンプル箱格納部8と、サンプル箱を所定の格納部7位置にて搬入出するサンプル搬入出部9と、上記機枠内にあって乾燥に必要な乾燥風調整機器を内蔵した乾燥風循環部10等からなる。
【0011】
上記サンプル投入排出部6には、サンプル箱5を、正面側に荷受けサンプル投入位置イ、水分測定のための水分測定サンプル投入位置ロ、同じく水分測定サンプル受け位置ハ、及び乾燥終了後のサンプル排出位置ニ、の夫々に対応すべくサンプル箱5挿入口11,12,13及び14を開口している。図外荷受け計量器より600gから1000gの範囲でサンプリングされた穀物は、適宜案内ダクト15を介してサイクロン16内に送られ、該サイクロン16の下部に接続する案内シュート17の下端部を上記荷受けサンプル投入位置イにのぞませる。
【0012】
上記の水分測定のための水分測定サンプル投入位置ロと水分測定サンプル受け位置ハとを接続する流下路には水分計18を設け、サンプルの更に一部を受けて単粒毎に水分測定しながら平均水分を算出しうる構成である。また、前記乾燥終了後のサンプル排出位置ニは後記の自主検定装置2の入り口部に供給案内するシュート19上端側をのぞませている。
【0013】
サンプル箱5は、上面5aが開放され底部5bは通気網部に構成されており、その正面側には断面よりもやや大きい形状の密閉兼用の正面板5cを有し、サンプル仕切り5dが、この正面板5cとは適宜間隔離れて設けられている。このような構成の各サンプル箱5,5…は、機枠正面の前記格納空間7,7…に略水平状態で出入りさせることができる。該格納空間7,7…は、サンプル箱5の受け面に通気網面積に見合うような通気開口7aを有し、後面下方から該通気開口7aに亘り乾燥風を導入する斜め方向の導入経路7bを形成している。7cはサンプル穀物を通過した乾燥排風の排風口である。
【0014】
上記サンプル箱5,5…の格納空間7,7…への搬入,排出、及びサンプル投入排出部6間への移動は、サンプル搬入出部9の搬入出ロボット20が司る。この搬入出ロボット20は、機枠前面上部と機枠下面のベース部材21とに設ける横レール22,23,23に沿って横移動可能に設ける縦連結枠24に、上下移動可能に装着されるもので、以下の構成である。縦連結枠24に沿って上下移動する移動枠25に、左右一対のレール26,26を設け、該レール26,26に沿ってサンプル箱を前後に搬入出する吸着ハンド28を備える搬入出体29を設けてなる。なお、吸着ハンド28のレール26,26に沿う前進は正逆転モータ27の正転により、逆の後進は該モータ27の逆転による。
【0015】
吸着ハンド28は、その先端部に通電により吸着作用し、かつ正逆転モータ30の作用にて上下反転する電磁石体28a、該電磁石体28aに一体の上下一対の突起部28b,28bからなり、前記サンプル箱5の正面板5cを吸着し併せて該正面板5cに形成する上下対称の反転用孔5e,5eに上記突起部28b,28bを係合して保持しうるもので、電磁石体28aの反転回動により、サンプル箱5の開放上面5aが上向く標準姿勢と、底部5bが上向く反転姿勢とに姿勢変更作動する構成である。31は縦連結枠25を左右方向に移動させる横移動モータ、32は移動枠26を上下縦移動させる縦移動モータである。33はサンプル箱5を吸着保持状態で格納空間から搬出した状態時にサンプル箱5の有無を検出しうる光学センサで、仕上搬送や中間の水分確認処理の際の搬出時にサンプル箱5が正規に吸着されているか否かを検知できる構成である。また、正規状態ではサンプル箱5を吸着保持しない動作(例えばサンプル箱搬出動作)にも関わらず当該センサがサンプル箱5検知するときは異常であることを警報しうる。
【0016】
前記サンプル乾燥機1の機枠内背面部において、乾燥風循環部10を構成している。多数のサンプル箱5,5…格納空間7,7…の背面側に、前後幅を適宜に狭く構成した空間を形成し、この空間部を隔てて観音開きの開閉扉34,34を設ける。開閉扉34の裏面側には、上下に長い断面矩形の一対のダクト35,35を構成する。なお該ダクト35の上下側は開放し、これらダクト途中にはヒータ36を設けると共に上面開放部側近傍には吸引ファン37を配設している。38は吸引ファン37近傍の機枠壁部に形成した外気導入口である。該ダクト35の下方出口には、温度センサ39を配設している。ヒータ36をオンし、吸引ファン37を作動すると、ダクト35内には上方から下方に抜ける通気状態となり、その間でヒータ36で温められ乾燥風となってダクト35の外側を上昇し、再び外気と混合しながらダクト35内を抜けて乾燥風を循環しうるもので、温度センサ39が検出する乾燥風温度が予め設定した乾燥風温度に達するとヒータ36の通電をオフし、再び当該設定温度以下に至ると通電オンしながら、循環する乾燥風温度を制御する構成である。
【0017】
従ってダクト35の内部を上方から下方に流通しながら乾燥風となり、ダクト35から出て上昇する乾燥風とで乾燥風循環経路10aが形成される。該乾燥風循環経路10aの上昇側経路には、前記サンプル箱格納空間7の各乾燥風導入経路7b,7b…がのぞみ、これら各導入経路7b,7b…入り口側に設ける導入ファン40,40…のオン作動によって乾燥風の一部が所定の乾燥風導入経路7bに導入される構成である。
【0018】
上記の実施例では、開閉扉34,34の裏面側にダクト35,35を構成したから、内部点検のために開閉扉34,34を開放すると、サンプル箱5の格納空間部背面が露出してこれら周辺の点検作業が容易である。なお、ダクト35内に乾燥風調整機器としてのヒータ36を設けたが、外部であっても良く、また、乾燥風調整機器としてはヒータのほか除湿器などがある。
【0019】
また、各乾燥風導入経路7b,7b…には導入ファン40,40…に代え、又は加えて開閉弁41,41…形態としてもよい。開閉弁41,41…は、個別にリレー(図示せず)で開閉制御される構成であり、同時に導入ファン40,40…をオン,オフ制御してもよい。42,42…は、機枠上面に設けた排気ファンで、上下に連設する格納空間7,7…の排風口に接続されていて、サンプル箱5に収容されたサンプル穀物中を通過した乾燥風を集合して排気しうる構成である。
【0020】
ついで自主検定装置2の構成について説明する。籾の自主検定装置は、籾を脱ぷ処理して後、整粒玄米と屑米とに篩い選別し、それらの比率を算出して荷受け籾の歩留まりを求め、籾持込み農家個々の金額換算の根拠とするものである。自主検定装置2の入り口ホッパ50に前記シュート19の排出口をのぞませ、サンプル乾燥完了後の籾を受入れ可能に構成している。該入り口ホッパ50は下方の計量ホッパ51に連通しており、該計量ホッパ51内投入待機状態で計量器52による計量が実行できる構成である。なお入り口ホッパ50には所定容積を越える過剰部分が案内シュート53を経由してスロワ54に直接供給される。
【0021】
一方計量ホッパ51内籾はゲートが開くとスロワ55を経由して機枠上部に設けられ、一対の脱ぷロール56,56を有する脱ぷ部57に供給される構成である。58は排塵ファン,59は排塵筒である。脱ぷ部57の下方には単一の回転選別筒60を設ける。該選別筒60には脱ぷ済の玄米が供給され、篩孔から漏下する屑米と選別筒内に残る整玄米とに選別する構成である。これら選別分離された屑米と整玄米とは順序を前後して上記計量ホッパ51に供給される構成であり、各別に計量されるものである。
【0022】
上記の計量された屑米,整玄米は前記過剰籾を受け入れるスロワ54に供給される。上記スロワ54の排出口は、サイクロン61を経由してサンプルパック機3に供給され、先にスロワ54に供給された籾・屑米・整玄米の順に袋詰めされる。即ち、サンプルパック機3は左右のロールから帯状フィルムが順次繰り出されるよう構成され、縦・横溶着機構の作動により袋状に成形されたフィルムに、先ず籾サンプルが供給され、自主検定作業の終了と共に屑米・整玄米の順で包装処理される。整玄米サンプルには、荷受けデータや計量検査データが印字された伝票が同封される。62は伝票出力印字機である。
【0023】
前記サンプル乾燥機1,自主検定装置2,サンプルパック機3の各運転制御及び各装置間の関連制御は制御部4が司る。例えば制御部4には、荷受日,穀物持込み者氏名,品種等の荷受データ入力部を備え、該入力データは、荷受計量機からサンプル籾を乾燥するサンプル乾燥機におけるサンプル箱5の状況、自主検定装置2による検定結果等を一元的に管理する指標となっている。
【0024】
上記制御部4は、サンプル乾燥機1の搬入出ロボット20の作動、水分計データの入力と関連出力、乾燥風循環部10のヒータ36のオンオフ制御、自主検定装置2の運転制御と各種計量信号の入出力処理、サンプルパック機3のシール機構の制御や伝票印字出力、封入出力など一連の動作を司っている。上例の作用について説明する。
【0025】
サンプル乾燥機1の搬入出ロボット20は、空のサンプル箱5を吸着ハンド28で吸着保持して、荷受サンプル投入位置イに挿入して待機する。荷受計量機からのサンプル穀物としての籾が搬送されてきて、その排出口からサンプル箱5内に投入される。搬入出ロボット20は予め設定された空きの格納空間7に向け、縦横に移動し、サンプル箱5はその正面に達する。続いてモータ27'の正転に伴い移動枠26毎前方に移動して、サンプル箱5を格納空間7に挿入するものである。ここで吸着ハンド28の通電を解くと、サンプル箱5は格納空間7に挿入維持されることとなる。移動枠26は退避動して次のサンプル箱搬入出に携わる。サンプル箱5が格納空間7に挿入保持されると、対応する導入ファン40を作動し、乾燥風循環部10の循環経路10aから乾燥風の一部を導入しつつサンプル籾に作用させて乾燥させる。上記荷受計量機で予め水分測定しているからそのデータを元に予測される乾減率で除して必要乾燥時間t1を算出し、t1−α(時間)経過したとき(α>0)、一旦サンプル箱5を搬出して水分測定サンプル投入位置ロに移動して挿入される。この位置で正逆転モータ30が逆転し、吸着ハンド28先端の電磁石体28aを反転回動させ、サンプル籾を排出する。この電磁石体28aは直ちに正転してサンプル箱5を標準姿勢に戻し、水分測定サンプル投入位置ロから水分サンプル受け位置ハに移動して待機する。一方排出された籾は漸次待機の後、シャッタ手段が開いて下方に流下し、その一部サンプルが水分計18に入り、単粒毎に所定粒が水分測定される。測定されずにそのまま流下したサンプル籾は下方で待機する上記サンプル箱5で受けられ、再び元の格納空間7に移動し搬入される。上記の測定水分に応じて残りの乾燥時間t2が算出され、タイマはこの時間を管理し、これが経過すると乾燥終了し、導入ファン40をオフする。もって乾燥風の供給は停止される。
【0026】
乾燥終了したサンプル箱5のサンプル籾は、サンプル排出位置ニにおいて、吸着ハンド28先端の電磁石体28aの反転により、シュート19に移される。この乾燥済サンプル籾は、自主検定装置2の入り口ホッパ50に至り、所定容積の籾が確保され、自主検定工程処理を受ける。余りの籾はそのままサンプルパック機3に投入されて袋詰めされ、残りの検定サンプルの投入を待つ。
【0027】
さて、自主検定装置2に入った籾は、先ず計量ホッパ51に入り、計量器52で計量される。その計量データは制御部4の所定記憶手段に記憶される。計量後直ちにスロワ55を経由して脱ぷ部57に供給される。一対の脱ぷロール56,56で脱ぷされた後、玄米は回転選別筒60に入って選別処理を受ける。予め設定された所定時間回転選別作用を受け、篩孔から漏下する屑米が先に計量ホッパ51に供給されて計量され、次いで整玄米が計量ホッパ51に排出されて計量される。これらの計量データも籾計量データと同様に出力され記憶される。なお、制御部4では、整玄米の歩留まりが計算される。
【0028】
計量ホッパ51での計量が完了すると直ちにスロワ55でサンプルパック機3に投入され屑米と整玄米とが別々に袋詰めされる。整玄米サンプルが投入される際には前記荷受データや上記計量データ,算出歩留まり等が印字された伝票が挿入され、一緒に封入される。上記実施例におけるサンプル箱5は、正面板5cに電磁石体28aが吸着する構成であるが、残留磁気による連れ出し、即ち、電磁石体28a非通電状態になってからもなお、吸着力が残存するための不具合を防止するため、突起部28b,28bには突き離し用のスプリング28c,28cを嵌入している。更に、サンプル箱5の左右側壁部には切欠段部5f,5fを形成し、サンプル箱5を挿入時には該格納空間7入口の下縁7aを係合して容易に抜き出し得ない構成とすることにより上記残留磁気の影響を無くすることができる。尚、サンプル箱5を格納空間7から搬出するときは、搬入出体29は吸着後僅かに上昇移動して、上記下縁7aから切欠段部5f,5fを離し、その後ゆっくりと水平搬出方向に移動する構成としている(図4)。

[0001]
[Industrial application fields]
The present invention relates to a sample grain drying apparatus that dries sample grains before being supplied to a self-assessment apparatus for receiving grains such as a drying preparation facility.
[0002]
[Prior Art and Problems to be Solved by the Invention]
Conventionally, as a sample grain drying apparatus, for example, a configuration described in Japanese Patent Laid-Open No. 2-1507048 is known. In this configuration, a sample box containing sample grains is stored in a space formed in the front / rear and horizontal sides of the main body frame of the sample dryer, and a heater and a suction fan are individually configured to correspond to each of these sample boxes. The heater and the suction fan are operated to dry the sample with respect to the necessary dry sample.
[0003]
In the above configuration, since the heater is individually provided, the cost increases, and the length of the sample dryer main body is increased in the front-rear direction, which inevitably increases the occupied area. In addition, since the configuration is such that the outside air is introduced and the drying air is generated by energizing the heater, there is a drawback that the drying time is not easily uniform due to the direct influence of the outside air temperature. In particular, when the outside air temperature is low, heating by the heater tends to be insufficient, the drying temperature does not rise, and drying is insufficient.
[0004]
[Means for Solving the Problems]
In view of the above, the present invention has attempted to realize a small and inexpensive sample drying apparatus, and has taken the following technical means. That is, in the sample grain drying apparatus that has a plurality of sample box storage spaces in the vertical and horizontal directions on the front side of the machine frame and that dries the sample grains stored in the sample box in the space, A drying air circulation path is formed on the back side of the stored sample box in the machine frame, and an individual introduction path to each sample box is observed in the drying air circulation path, and an entrance of the individual introduction path The unit is provided with a switching means for switching between introduction and non-introduction of dry air , a duct member in which the front and rear sides of the dry air circulation path are opened to the back side space of the sample box, and a dry air adjusting device such as a heater and a dehumidifier, A circulation fan is provided, and the inside and outside of the duct are circulated and ventilated by the operation of the circulation fan .
[0005]
[0006]
[0007]
[Action and effect of the invention]
Since the present invention is configured as described above, a drying air circulation path is always formed, and the drying air circulates. Therefore, the invention is hardly affected by temperature fluctuations due to fluctuations in the outside air, etc., and thus predicts the drying time of the sample grain. It is easy to stand up and the accuracy is improved. Further, it is not necessary to provide a heater for each storage space for storing the sample box, which can contribute to cost reduction.
[0008]
[0009]

It is the structure which can detect whether it is done. Moreover, when the sensor detects the sample box 5 in spite of an operation (for example, a sample box unloading operation) in which the sample box 5 is not sucked and held in the normal state, an alarm can be given.
[0016]
A drying air circulation unit 10 is formed on the rear side in the machine frame of the sample dryer 1. A space having an appropriately narrow front and rear width is formed on the back side of the large number of sample boxes 5, 5..., The storage spaces 7, 7,. On the back surface side of the opening / closing door 34, a pair of ducts 35, 35 having a rectangular section that is long in the vertical direction are formed. The upper and lower sides of the duct 35 are opened, a heater 36 is provided in the middle of these ducts, and a suction fan 37 is disposed in the vicinity of the upper surface opening portion side. Reference numeral 38 denotes an outside air inlet formed in the machine frame wall near the suction fan 37. A temperature sensor 39 is disposed at the lower outlet of the duct 35. When the heater 36 is turned on and the suction fan 37 is actuated, the duct 35 is ventilated from above to below, and is heated by the heater 36 during that time to become dry air, rises outside the duct 35, and again becomes the outside air. It is possible to circulate the drying air through the duct 35 while mixing. When the drying air temperature detected by the temperature sensor 39 reaches the preset drying air temperature, the heater 36 is turned off and again below the set temperature. In this configuration, the circulating drying air temperature is controlled while energization is turned on.
[0017]
Accordingly, the drying air circulation path 10a is formed by the drying air that flows from the upper side to the lower side of the duct 35 and becomes the drying air rising from the duct 35 and rising. The drying air introduction path 7b, 7b,... Of the sample box storage space 7 is seen in the ascending side path of the drying air circulation path 10a, and the introduction fans 40, 40,. A part of the drying air is introduced into the predetermined drying air introduction path 7b by the on-operation.
[0018]
In the above embodiment, the ducts 35, 35 are formed on the back side of the open / close doors 34, 34. Therefore, when the open / close doors 34, 34 are opened for internal inspection, the back of the storage space of the sample box 5 is exposed. These peripheral inspections are easy. In addition, although the heater 36 as a dry-air adjustment apparatus was provided in the duct 35, it may be outside and there exist a dehumidifier other than a heater as a dry-air adjustment apparatus.
[0019]
Moreover, it is good also as a form of on-off valve 41, 41 ... instead of or in addition to the introduction fans 40, 40 ... in each dry wind introduction path 7b, 7b .... The on-off valves 41, 41... Are individually controlled to open / close by relays (not shown), and the introduction fans 40, 40. 42, 42... Are exhaust fans provided on the upper surface of the machine frame, connected to the air outlets of the storage spaces 7, 7... Connected vertically and dried through the sample grain accommodated in the sample box 5. It is a configuration that can collect and exhaust the wind.
[0020]
Next, the configuration of the self-test apparatus 2 will be described. The self-assessment device for cocoons, after removing the cocoons, sifts and sorts the sized unpolished rice and waste rice, calculates the ratio of them and calculates the yield of the receiving potatoes. It is the basis. The outlet of the chute 19 is looked into the entrance hopper 50 of the self-test device 2, and the soot after sample drying is completed can be received. The entrance hopper 50 communicates with the lower weighing hopper 51 and is configured so that weighing by the weighing instrument 52 can be executed in the waiting state in the weighing hopper 51. The excess portion exceeding the predetermined volume is directly supplied to the entrance hopper 50 via the guide chute 53 to the slot 54.
[0021]
On the other hand, the inner tub of the weighing hopper 51 is provided at the upper part of the machine frame via the slot 55 when the gate is opened, and is supplied to the detaching section 57 having a pair of detaching rolls 56, 56. 58 is a dust exhaust fan and 59 is a dust exhaust cylinder. A single rotary sorting cylinder 60 is provided below the removal unit 57. The crushed brown rice is supplied to the sorting cylinder 60, and is classified into waste rice leaking from the sieve hole and conditioned brown rice remaining in the sorting cylinder. The sorted and separated waste rice and conditioned brown rice are supplied to the weighing hopper 51 in order and are weighed separately.
[0022]
The above-mentioned weighed waste rice and brown rice are supplied to a slot 54 that receives the excess rice cake. The outlet of the slot 54 is supplied to the sample pack machine 3 via the cyclone 61 and packed in the order of rice bran, waste rice, and brown rice previously supplied to the slot 54. That is, the sample pack machine 3 is configured so that the belt-like film is sequentially drawn out from the left and right rolls, and the bag sample is first supplied to the film formed into a bag shape by the operation of the vertical and horizontal welding mechanisms, and the self-assessment work is completed. At the same time, it is packaged in the order of waste rice and brown rice. A slip printed with receipt data and weighing inspection data is enclosed with the cooked brown rice sample. 62 is a slip output printing machine.
[0023]
The control unit 4 controls each operation control of the sample dryer 1, the self-test device 2, and the sample pack machine 3 and the related control between the devices. For example, the control unit 4 includes a receiving data input unit such as a receiving date, a name of a grain taker, and a variety, and the input data includes the status of the sample box 5 in the sample dryer for drying the sample basket from the receiving weighing machine, and voluntary. This is an index for centrally managing the test results by the test device 2.
[0024]
The control unit 4 operates the loading / unloading robot 20 of the sample dryer 1, inputs moisture meter data and related outputs, turns on / off the heater 36 of the drying air circulation unit 10, controls the operation of the self-test device 2, and various measurement signals. It controls a series of operations such as input / output processing, control of the sealing mechanism of the sample pack machine 3, slip printing output, and sealed output. The operation of the above example will be described.
[0025]
The carry-in / out robot 20 of the sample dryer 1 sucks and holds the empty sample box 5 with the suction hand 28, inserts it into the receiving sample input position a, and stands by. The soot as the sample grain from the load receiving weighing machine is conveyed and is put into the sample box 5 from the discharge port. The loading / unloading robot 20 moves vertically and horizontally toward the empty storage space 7 set in advance, and the sample box 5 reaches the front thereof. Subsequently, as the motor 27 ′ rotates forward, the moving frame 26 moves forward to insert the sample box 5 into the storage space 7. When the energization of the suction hand 28 is released here, the sample box 5 is inserted and maintained in the storage space 7. The moving frame 26 is retracted and engaged in the next sample box loading / unloading. When the sample box 5 is inserted and held in the storage space 7, the corresponding introduction fan 40 is actuated, and a part of the drying air is introduced from the circulation path 10 a of the drying air circulation unit 10 to act on the sample basket and dry. . Since the moisture is measured in advance by the above-mentioned load receiving weighing machine, the necessary drying time t1 is calculated by dividing the data by the predicted drying rate, and when t1−α (time) has elapsed (α> 0), Once the sample box 5 is unloaded, it is moved to the moisture measurement sample loading position B and inserted. At this position, the forward / reverse motor 30 rotates in the reverse direction, rotates the electromagnet body 28a at the tip of the suction hand 28, and discharges the sample basket. The electromagnet 28a immediately rotates forward to return the sample box 5 to the standard posture, moves from the moisture measurement sample loading position B to the moisture sample receiving position C, and stands by. On the other hand, the discharged soot gradually waits, then the shutter means opens and flows downward, a part of the sample enters the moisture meter 18, and moisture is measured for a predetermined grain for each grain. The sample soot that has flowed down without being measured is received by the sample box 5 waiting at the lower side, and again moved to the original storage space 7 and carried in. The remaining drying time t2 is calculated according to the measured moisture, and the timer manages this time. When this time elapses, the drying ends and the introduction fan 40 is turned off. Accordingly, the supply of dry air is stopped.
[0026]
The sample basket in the sample box 5 that has been dried is transferred to the chute 19 by reversing the electromagnet body 28a at the tip of the suction hand 28 at the sample discharge position D. This dried sample basket reaches the entrance hopper 50 of the self-test apparatus 2, a predetermined volume of the kite is secured, and is subjected to a self-test process. The remaining bag is put into the sample pack machine 3 as it is, packed in a bag, and waits for the remaining test samples to be put in.
[0027]
The soot that has entered the self-test device 2 first enters the weighing hopper 51 and is weighed by the weighing instrument 52. The measurement data is stored in a predetermined storage unit of the control unit 4. Immediately after the measurement, it is supplied to the removal unit 57 via the slot 55. After being deflated by the pair of deflation rolls 56, 56, the brown rice enters the rotary sorting cylinder 60 and undergoes a sorting process. The waste rice that has been subjected to the rotational sorting action for a predetermined time set in advance and leaks from the sieve hole is first supplied to the weighing hopper 51 and weighed, and then the conditioned rice is discharged to the weighing hopper 51 and weighed. These weighing data are output and stored in the same manner as the soot weighing data. The control unit 4 calculates the yield of conditioned brown rice.
[0028]
As soon as the weighing with the weighing hopper 51 is completed, the waste packer and the brown rice are separately packed into the sample pack machine 3 by the slot 55. When the brown rice sample is put in, a slip printed with the receipt data, the weighing data, the calculation yield, etc. is inserted and sealed together. The sample box 5 in the above embodiment has a configuration in which the electromagnet body 28a is attracted to the front plate 5c, but the attraction force remains even after being brought out by residual magnetism, that is, even when the electromagnet body 28a is not energized. In order to prevent this problem, the protrusions 28b and 28b are fitted with springs 28c and 28c for separation. Further, notch step portions 5f and 5f are formed on the left and right side wall portions of the sample box 5, and when the sample box 5 is inserted, the lower edge 7a of the entrance of the storage space 7 is engaged and cannot be easily extracted. Thus, the influence of the residual magnetism can be eliminated. When unloading the sample box 5 from the storage space 7, the loading / unloading body 29 moves up slightly after being sucked to release the notch steps 5f and 5f from the lower edge 7a, and then slowly moves in the horizontal unloading direction. It is set as the structure which moves (FIG. 4).
