Última Improved process control by surface temperature-controlled drying on the example of sweet potatoes Organic Eprints Bantle, M.; Kopp, C.; Claussen, I.C.. Convective drying of food has a big impact on the quality of the product in terms of sensory quality and energy consumption. The temperature of the product during the drying process is a major parameter since exceeding can cause damages to the product. The surface temperature of the product can be measured non-disruptive and contact-free with IR-sensors and this information is used as input parameter for the dryer control. A convective drying chamber was modified with modern sensors and a smart control system to control the surface temperature during the drying process and evaluate the influences on the product in terms of sensory quality parameters like shrinkage, deformation and colour alternation. The dehydration rate in the first drying period of the... Tipo: Conference paper, poster, etc. Palavras-chave: Food security; Food quality and human health Processing; Packaging and transportation. Ano: 2019 URL: http://orgprints.org/36583/1/PaperEuroDrying11.06.2019_Bantle_PrePrint.pdf Design of a CO2 heat pump drier with dynamic modelling tools Organic Eprints Jokiel, M.; Bantle, M.; Kopp, C.; Claussen, I.C.; Tolstorebrov, I.. Drying is an energy and time intensive process which thermal energy demand is mostly provided by fossil resources. Especially in the food processing industry it is important to increase the energy efficiency of drying processes in terms of organic products and sustainability. The potential of using a heat pump with R744 (CO2) as a working media to provide the thermal energy was investigated for typical food drying temperature of 50 °C at a relative humidity of 20 %. A dynamic heat pumpassisted dryer model has been developed and validated. The model was created with respect to heat transfer, pressure loss and flow requirements. The simulated results showed that a closed-loop heat pump assisted drying process has the potential to reduce the energy demand by...
