Energy efficient drying of solutions and suspensions by superheated steam spray drying (Bachelor Thesis, Project Work, Master Thesis, starting by arrangement)
Spray drying is a widely used technology in the food industry to remove water from food products and is known for its ability to extend the shelf life of products. Traditionally, spray drying has been carried out in an air atmosphere. One way to increase energy efficiency is to use superheated steam as a drying medium.
With the use of a pilot plant, we are investigating the spray drying process with superheated steam and its applicability to various food materials. With regard to this topic, we offer a Bachelor's or Master's thesis with preceding project work.
Characterization of the swelling of food powders (Bachelor Thesis, Project Work, Master Thesis, starting by arrangement)
Prior to further processing or consumer use, food powders typically have to be rehydrated. During rehydration, swelling often occurs. This can lead to undesired effects, e.g. lump formation and delayed sinking or dispersion. To enable prediction of swelling effects on powder rehydration, swelling of food powders needs to be quantified.
For quantification of swelling, measurement methods shall be evaluated regarding their applicability to different food powder systems. We offer a Bachelor Thesis or a Project Work followed by a Master Thesis in this research area.
