Sparger effects during the concentration of synthetic fruit juices by direct-contact evaporation
TL;DR: In this paper, the influence of the diameter of the sparger on the performance of a direct-contact evaporator applied in the concentration of synthetic fruit juices was addressed, and experiments were conducted in a bench scale unit using water, a sucrose solution (11.2",wt.%) and an ethyl acetate (1.0",g/L) solution as continuous phases with either a perforated or porous plate as sparger.

A New Route Combining Direct-Contact Evaporation and Vapor Permeation for Obtaining High-Quality Fruit Juice Concentrates. Part II: Modeling and Simulation
TL;DR: In this article, a mathematical framework is presented for simulating each step of the proposed juice-processing route, which combines a transient, well-mixed model for the liquid phase with a detailed model for heat and multicomponent mass transfer in superheated bubbles that was previously developed.

Application of Microbubbles Generated by Fluidic Oscillation in the Upgrading of Bio Fuels
TL;DR: In this paper, the authors used hot micro-bubbles to remove volatile components from the liquid phase and thus minimizing the sensible heat transfer to the liquid by injecting a hot carrier gas in the form of microbubbles.
Journal ArticleDOI
On the estimation of the gas-side mass-transfer coefficient during the formation and ascension of bubbles
TL;DR: Using a recently developed model for the simultaneous heat and multicomponent mass transfer during the formation and ascension of superheated bubbles, concentration profiles within a bubble during the stripping of diluted ethyl acetate solutions were determined and then used in the computation of the corresponding mass-transfer coefficient on the gas side, k G.

Performance evaluation of a baffled rotating contactor for the concentration of fruit juice by air stripping
TL;DR: In this article, a baffled rotating contactor and volumetric mass transfer coefficient determined towards exploring an alternate strategy for the concentration of fruit juice was proposed, based on the stripping of water from fruit juice by an unsaturated gaseous stream.
