2. 1. Some Fluid Dynamic Characteristics in the Scale-up of Rushton Turbine-Agitated Tanks

   Author : Eva Ståhl Wernersson; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chemical technology and engineering; Livsmedelsteknik; Food and drink technology; Rushton turbine; turbulent kinetic energy; geometry; local energy dissipation rate; power input; scale-up; anemometry measurements; agitated tanks; turbulence; Kemiteknik och kemisk teknologi;

   Abstract : Turbine-agitated tanks are used in chemical and biochemical applications to increase mixing which, in turn, affects the yield, productivity and product quality. The purpose of this work was to study the hydrodynamic influence on the scale-up of turbine-agitated tanks, commonly used in fermentation. READ MORE

4. 2. A Particle Image Velocimetry Study of Bubbly Gas-Liquid Flow

   Author : Xiaoyun Tu; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulent dispersion; Food and drink technology; Livsmedelsteknik; turbulence; Rushton turbine; stirred tank; slip velocity; bubbly gas liquid two-phase flow; coherent structure; CCD camera; PIV; POD;

   Abstract : The aim of this work is to build a framework that can be used for characterizing the bubbly gas liquid turbulent flow in the stirred bioreactor tank. To this end we have developed and modified techniques with which to measure the velocity of both dispersed gas and carrier liquid phases by the optical measurement technique, a 2-CCD camera Particle Image Velocimetry (PIV) system; and to characterize the turbulence by the wavelets tool, Proper Orthogonal Decomposition (POD).

5. 3. Membrane emulsification: modelling interfacial and geometric effects on droplet size

   Author : Marilyn Rayner; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pore geometry; membrane emulsification; Gases; Surface Evolver; fluid dynamics; plasmas; Gaser; fluiddynamik; plasma; Chemical technology and engineering; Kemiteknik och kemisk teknologi; Food and drink technology; modelling; Livsmedelsteknik;

   Abstract : Emulsification is an important unit operation used in the pharmaceutical, food, and cosmetic industry. Membrane emulsification is a relatively new membrane technology which allows the production of emulsion droplets under controlled conditions with a narrow droplet size distribution. READ MORE

6. 4. Heat-Induced Cell Membrane Injury of Vegetable Tissues -An applied study on potatoes

   Author : Gerardo Gonzalez-M; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; PME; active transport; Cell membrane injury; potatoes;

   Abstract : Heat processing of vegetables involves the use of temperatures above the physiological limit which affect the cellular structures of the tissue and induce a series of events at cell level that will in turn be reflected in the transport properties of the tissue. One of the most important cellular structures from the mass transport point of view is the cell membrane since it represents the physical barrier to the transport of nutrients into and out of the cell.

7. 5. Optimisation and modelling of aroma recovery by pervaporation

   Author : Jenny Olsson; Livsmedelsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; optimisation; mass transfer; modelling; pervaporation; aroma recovery; Livsmedelsteknik;

   Abstract : During production of concentrated fruit juices, both physical and chemical losses of aroma compounds occur due to heat treatment such as pasteurisation and evaporation. This leads to an inferior quality of the final product. READ MORE
