Experiment on the Effect of Water Jet upon the Melting Process of an Ice Sphere in a Cylindrical Bath

Abstract

Investigation on mass transfer from foods such as pig bones to water contained in a cylindrical vessel of extraction processes has been carried out based on a model experiment. The water bath is agitated by a water jet injected from a centered bottom nozzle. The mass transfer coefficient is estimated from the heat transfer coefficient for an ice sphere because analogy between mass transfer and heat transfer holds under turbulent flow conditions. An estimation method of the mass transfer coefficient is proposed.
