Simplified model of airflow and heat transfer in a pallet of food product generating heat

 

During storage, pallets of food product generating heat (e.g., cheese, fruit, and vegetable) are exposed to low velocity ventilation. In addition, the boxes have often little perforation. Therefore, airflow is weak inside the boxes located downstream of the pallet; and if the product generates heat, its temperature can rise above the recommended one.

Computational fluid dynamics modeling can predict these phenomena but needs an expertise of numerical fluid flow, a detailed description of product and packaging and leads to expensive computational costs. A simplified model was developed by French Researchers based on a hydraulic network analogy and the results were published in the Journal of Food Process Engineering

Given the vent holes areas of the boxes and the heat generation, it predicts the global air flow (flow through the box faces) and the product temperature. The predictions are in good agreement with experimental data. The software (Matlab executable) is easy to use and needs only some seconds to compute. It can be used to predict temperature evolution along a cold chain and to improve packaging and logistic operating conditions. Practical applications. Based on a on a hydraulic network analogy, a simplified zonal model of airflow and heat transfer in a pallet of food generating heat is built with the Matlab software. It takes into account the vent holes areas of the boxes and the heat generation, and allows predicting the distribution of air fluxes through the box faces and the product temperature. The major advantage of this model is that it is easy to use and needs only some seconds to compute. Therefore, it can be easily used in industrial field.
