The Sorption of Water in the Agricultural Materials

Takaharu Kameoka; Kazuo Horibe

The attempt at a statistical treatment of water sorption by foods was made, based on an approximate method for deriving the sorption isotherm from the probability density function of adsorption energies. The use of Weibull distribution leads to the Dubinin-Astakhov(DA) equation and it was shown that this isotherm is applied successfully to both the non-porous and porous foods.

Computer Simulated Facility Investment Plan. (Part 2). Cutting Operational Expenses in Mushroom Cultivation Facilities with More Efficient Environmental Controls.

きのこ栽培室の設計にあたり空調機パワーの設定は, 従来では栽培者が経験的に見当をつけ設計していたのでパワー不足や過剰投資が起こった.本報ではより完全な環境制御を目指すため, これまでの研究成果に基づいて我々が開発したシミュレーションソフトを用いて, 最適設備投資計画と実践的制御の方法について検討した結果, 以下の結論を得た.1.栽培瓶数15万本クラスの標準的規模のきのこ栽培室 (長野市) で必要な最適設備投資をT.F.N.で表せば, 換気扇 (0.45, 0.55, 0.65) m3/s, 冷房機 (20.0, 21.0, 22.0) kW, 暖房機 (5.0, 8.0, 11.0) kW, 加湿器 (18.0, 19.0, 20.0) kg/hとなる.このとき, 空調機にインバータ機種を採用すれば, 通常の気温では運転経費を節約でき, 一時的なパワー不足にも対応できる.2.栽培室を常に22℃付近に維持することにこだわらず, 気象条件が特に厳しいときには19~25℃程度にあれば良いとすれば, 設備投資を縮小し冷暖房費を節約することができる.またこの時, 炭酸ガス濃度を4500ppm程度に維持することにこだわらず3000~6000ppmあれば良いと考えれば, 換気量の増減により室温を22℃程度に補正することも可能となる.

本報では, きのこの栽培調整や形状制御を可能とする環境制御のための適正な設備投資を目指し, これまでの研究成果にもとづき, 環境制御状態と空調機稼働状態を示すシミュレーションソフトを開発するとともに, 栽培瓶数15万本クラスの標準的規模のきのこ工場を例にとり, 栽培環境制御の実態を明らかにした.1.現状のきのこ栽培室では, きのこから発生した炭酸ガスを外気で希釈してるので, 外気導入により, 夏季昼下がりはわずか1~2分, 冬季明け方は2~6分で室内環境が不適正になる.したがって, きのこと他の野菜類との同室栽培により炭酸ガス濃度の調整を行い, 設備投資を抑えることが重要な課題である.2.夏季昼下がり, 栽培室は0.5m3/s換気扇, 21kW冷房機により, 炭酸ガス濃度 (4352, 4468, 4585) ppm, 温度 (21.7, 21.9, 22.0) ℃, 湿度 (98.0, 99.3,100.0) %に制御できた.このとき, 実際の幾多の工場で発生しているようなパワー過不足を生じなく適正環境となる.また加湿器は必要なかった.稼働率は換気扇89.2%, 冷房機96.2%であった.冬季明け方, 冷房機を使用しないと温度が目標上限を若干越える (約0.2℃, 3~4min/h).0.5m3/s換気扇, 21kW冷房機, 6kW暖房機, 19kg/h加湿器を使用すれば, 湿度は (67.6, 68.6, 70.0) %になるが, 夏季と同様に適正に制御できた.稼働率は換気扇89.2%, 冷房機5.6%, 暖房機86.4%, 加湿器92.1%であった.

Economic Analyses by the Use of Fuzzy Number on Plant Production Environment Systems. (Part 2). Decision Making of Investment On Mushroom Factories of Hypsizigus marmoreus.

Masahiko Matsuyama; Yasushi Terasawa; Kazuo Horibe

Economic Analyses by the Use of Fuzzy Number On Plant Production Environment Systems (Part 2) Decision Making of Investment on Mushroom Factories of Hypsizigus marmoreus Masahiko MATSUYAMA, Yasushi TERASAWA and Kazuo HORIBE Faculty of Domestic science, Nagoya Women’s University, Mizuho-ku, Nagoya 467, Japan * Nagano Denpa technology center(Co.), Okada Shinonoi, Nagano 381-2225, Japan **Faculty of Bioresource, Mie University, Kamihama, Tsu 524, Japan Abstract The market price of H. marmoreus rose during the first 9 years of its supply to the Market, from 1973 to 1982, and then fell(Fig.1). It sells at a very high price during the autumn season, and at a low price during the summer season(Fig.2). Let Rp be the year of grace, and h be the membership function of fuzzy model, the Fuzzy equation ~X (Rp )predicts the future market price of H. marmoreus by analyzing some data from 1982 to 1992.
