<p>PROBLEM TO BE SOLVED: To provide small-sized test equipment which can simulates a manuring procedure under various temperature conditions. SOLUTION: In order to ensure the reproducibility of experiment, a reaction vessel 11 is kept under a fixed temperature for a prescribed time in the temperature holding mode and, thereafter, is subjected to pseudo-thermal insulation in the temperature follow-up mode and the temperature of fermenting substance CO is naturally elevated. In such a case, the initial conditions of the fermenting substance CO is allowed to coincide with each other and the experiment having high reproducibility is made possible. Otherwise, as another experiment, the reaction vessel 11 is preliminarily subjected to pseudo-thermal insulation in the temperature follow-up mode, the temperature of the fermenting substance CO is naturally elevated and the temperature hysteresis at that time is stored. Subsequently, by the exchange, etc., of the fermenting substance CO in the reaction vessel 11, the temperature of the reaction vessel 11 is regulated in the temperature forced mode. In such a experiment, the reproducibility of the initial pseudo-thermal insulation test can be confirmed.</p> |
