摘要
利用传热学理论对双孢蘑菇预冷过程进行分析,通过集总参数模型对其预冷时间进行预测,并对该数学模型进行了试验验证。结果表明:该数学模型可以用于预测双孢蘑菇在预冷过程中的温度变化,可预测不同条件下双孢蘑菇降温过程;冷却速率随着风速的增加而增加,二者符合幂函数关系。拟合不同风速下蘑菇中心温降曲线,得到其拟合曲线方程。
The pre-cooling process of Agaricus bisporus by using heat transfer theory was analyzed. The cooling time was predicted with the lumped parameter model, and the performance of the mathematical model was checked using experimental data. It was turned out that the model could be used to predict the temperature change during the pre-cooling process of Agaricus bisporus, and it could be used to predict different conditions on pre-cooling. At the same time, the increase in cooling air velocity beyond the above values did not affect the cooling rate significantly. The pre-cooling rate was increased with the increase of the air velocity, and fitted the power function. The equation of the fitting curves between the air velocity and central temperature was obtained.
