Process and Product Analysis of the Village-Scale Processing of Sweetpotato in the Philippines OAK
TAN, Daniel Leslie S.; MIYAMOTO, Keiji; ISHIBASHI, Ken-ichi; MATSUDA, Kiyoaki; SATOW, Tadatoshi; タン, D. L. S.; 宮本, 啓二; 石橋, 憲一; 松田, 清明; 佐藤, 禎稔.
Village level root crop processing system in the Philippines was evaluated using sweetpotato (cv. Kogane sengan and Shiro satsuma) as materials. The PRCRTC chipper/grater had more pronounced power fluctuation in grating than in chipping and peaking during the loading of the roots. The grinder had the highest energy requirement than the other machines,but the power fluctuation was relatively stable regardless of the amount of materials loaded. The finisher had a stable power fluctuation,and its power increased as either the loading rate or rpm was increased. Size and weight of chips and fineness modulus of grates were affected by the rpm of the blades. Percent recoveries of dried chips,fine flour and dried grates for Kogane sengan,at 12% moisture content,...

ナガイモ掘取り機の収穫作業体系と作業性能および負担面積 OAK
松田, 清明; 宮本, 啓二; 佐藤, 禎稔; MATSUDA, Kiyoaki; MlYAMOTO, Keiji; SATOW, Tadatoshi.
近年,連続的にナガイモ掘取りを行う機種が開発 され,利用され始めている.今回,従来から使用さ れているバックホー方式(K機)と掘取り方式の異なる3機種(A,SおよびT機)の掘取り機について, 作業性能を明らかにするとともに,各掘取り機の負 担面積や利用経費について検討した. 1)収穫作業に携わる作業者数は6-12人と供試機 により異なるが,概して能率の高い機種ほど作業 者は多い. 2 )各供試機の作業能率は, K機が2.2a/hであるのに 対して, A機が5.8a/h, S機は3.8a/h, T機が3.7a/h といずれも高能率である.10a当り投下労働量は, それぞれ27.8-32.4,20.8,21.0,21.9人・時である. 3 )各供試機の作業精度は,無傷の本数割合がいず れも98%以上と高く,損傷や掘残しの割合は極め て低い. 4 )各供試機の負担面積は, A機が4ha,K機は1.5ha, S機とT機が2.5haであり,その時のha当り機械利 用経費は,それぞれ556千円, 1,113 -1,173千円, 687千円, 699干円となる.各供試機の導入が不利 となる下限面積は, K機を他作業に利用するとい ずれも0.49-0.56haの範囲である. 従って, A機は高能率であるが多くの労働力や 前後処理に他の作業機を必要とし,大規模農家向 きである.また, K機は作業能率が低いが,少人 数でも作業が可能なことから小規模農家に適し,S機やT機は中規模農家に適している. Diggers of the backhoe type, the trencher type, and the plow type have been mainly used to harvest Chinese yams until...

三次元視覚センサによるキャベツ結球の形状計測と収穫適期判定 OAK
佐藤, 禎稔; 宮本, 啓二; 松田, 清明; SATOW, Tadatoshi; MIYAMOTO, Keiji; MATSUDA, Kiyoaki.
キャベツ選択収穫機のための収穫適期判定を目的とし, レーザ距離センサによる三次元視覚センサを開発した。三次元視覚センサは, 外葉を含めたキャベツ結球全体の三次元形状を非接触で検出し, また結球頂部の半展開葉の状態も計測できた。「アーリーボール」の場合, 計測波形をもとに球径と半展開葉の有無で判定すると収穫適期のランク3では77%のキャベツが収穫適と判定され, 適期前のランク2では8%の誤判定が見られた。さらに, 圧縮法の硬さを組み合わせた場合, ランク2の誤判定とランク3の判定精度は, それぞれ8%, 95%であった。また,「金系201号」では球径のみの判定法で, それぞれ7%, 91%の値を示した。 Three-D vision sensor to determine the harvest maturity of cabbage heads was developed for use in selective cabbage harvester. The sensor measured a 3-D image of the entire head formation including the outside leaf of the cabbage and the condition of curled leaf. For Early ball,using the sensor based on head size and curled leaf,77% of the cabbage heads were judged as the best cabbage to harvest in rank 3 while 8% were misjudged in rank 2 (immature...

圧縮法によるキャベツ収穫適期判定の基礎的研究 OAK
佐藤, 禎稔; 宮本, 啓二; 松田, 清明; SATOW, Tadatoshi; MIYAMOTO, Keiji; MATSUDA, Kiyoaki.
近年, キャベツ収穫には一斉方式の収穫機が導入されているが, 実際には生育差が大きいために生産者からは3回程度に分けて選択収穫することが望まれている。本研究は選択収穫機のための適期判定装置の開発を目的とし, 結球頂部を2段階圧縮して変位と荷重の関係から適期判定する方法について検討した。結球は, 熟度が進むほど変位荷重曲線の傾きは大きくなり, 収穫適期となるランク3で最も変位が小さく硬くなる。本判定法の荷重35~40Nの場合, 未熟なランク2では「アーリーボール」で16%,「金系201号」で8%のキャベツを収穫適と誤判定したものの, 収穫適となるランク3では両品種とも81%の精度で適期判定した。 Presently,cabbage harvesting is done manually by selectively picking up cabbage heads directly from the field three times per harvest season. However,researches are being conducted that will lead to the development of simultaneous harvester. In this research,the system that determines the maturity of the cabbage head was developed for selective harvesting. The system determined the maturity by the relationship of the displacement and load of the cabbage head...
