The Formulae of Aeration and Ventilation for Storage Room of Farm Products

Abstract

1) The formulae were derived for the estimation of the air flow rate of aeration and ventilation to control both the maximum temperature of the storage products and the gas concentration of carbon dioxide in the aeration system containing the products in storage room equipped with ventilator.
2) The Gore's equation on the temperture rise and the respiration rate of the fruits was extended that not only added the effect of the moisture content but also adapted to the cereal grains.
3) The respiration properties of rough rice was measured, and the six respiration coefficients, which chracterized the extended equation and was necessary for the practical use of the formulae, were obtained by the least squre method from both the measured data and the published data of several farm products.
4) An example was showed for design calculation.
