Monitoring a vial freeze-drying process without interfering with product dynamics is a challengin...g issue. This paper presents a novel device constituted by an IR camera designed to be placed inside the drying chamber, able to monitor the temperature of the vials, very close to that of the product inside.
Infrared imaging sensors were proposed in the past years for the real-time monitoring and control... of the Vacuum Freeze Drying (VFD) process. In order to extract reliable, real-time, and quantitative features from images collected by these sensors, a robust and automated image processing pipeline is required.
The atmospheric freeze-drying process can be significantly accelerated using power ultrasound. Th...is paper aims to investigate the effects of this technology on the global energy consumption of the process and its environmental impact.
The Vacuum Freeze Drying (VFD) process is a low temperature drying technique that can be used for... food preservation. The aim of this work is to evaluate how VFD operating conditions affect the amount of some nutritional compounds of eggplants (Solanum melongena L.).
