Quantification Model for Estimating Temperature Field Distributions of Apple Fruit
Abstract : A quantification model of transient heat conduction
was provided to simulate apple fruit temperature distribution in the
cooling process. The model was based on the energy variation of apple
fruit of different points. It took into account, heat exchange of
representative elemental volume, metabolism heat and external heat. The
following conclusions could be obtained: first, the quantification model
can satisfactorily describe the tendency of apple fruit temperature
distribution in the cooling process. Then there was obvious difference
between apple fruit temperature and environment temperature. Compared to
the change of environment temperature, a long hysteresis phenomenon
happened to the temperature of apple fruit body. That is to say, there
was a significant temperature change of apple fruit body in a period of
time after environment temperature dropping. And then the change of
temerature of apple fruit body in the cooling process became slower and
slower. This can explain the time delay phenomenon of biology. After
that, the temperature differences of every layer increased from centre
to surface of apple fruit gradually. That is to say, the minimum
temperature differences closed to centre of apple fruit body and the
maximum temperature differences closed to the surface of apple fruit
body. Finally, the temperature of every part of apple fruit body will
tend to consistent and be near to the environment temperature in the
cooling process. It was related to the metabolism heat of plant body at
any time.
