The FrostWave team has just started working on the concept of a new device!

The first changes will concern the cooling system. A major step will be to switch from the current synthetic refrigerant with a relatively high GWP (Global Warming Potential) to a natural working fluid. Thanks to the analysis carried out by the NTNU team, two potential substitutes for the currently used refrigerant were identified, namely R290 (propane) and R1270 (propylene).

On October 27, part of the SUT team visited the Zespół Szkół Łączności im. prof. Stanisława Fryzego in Gliwice. The purpose of the visit was to familiarize high school students with what research groups operating at the Silesian University of Technology do, and thus what they themselves would have the opportunity to do in the near future by joining our ranks. As part of the promotional presentation, prof. Jacek Smołka and MSc.

On Saturday, October 9, 2021, we had the pleasure to participate in the 16th edition of the Scientists' Night of the Silesian University of Technology. During the visit to the SUT laboratory, our guests could learn a bit about the freeze-drying of food and get acquainted with our experimental rig. Thank you for visiting us and we hope to meet you next year at the next edition of the Scientists' Night!

We are pleased to announce that the freeze dryer has been successfully equipped with high-class Endress + Hauser sensors. Additional equipment allows for accurate measurement of pressure and flow of the working fluid in the cooling system. Due to the dimensions of the sensors, the SUT team prepared a special table on which they were placed. In addition, the data acquisition system has been expanded with additional modules that support the devices described above.

After a series of successful experiments conducted in SUT laboratory, in the next step, the lyophilisator will be equipped with high-quality pressure and flow sensors for comprehensive monitoring of the refrigeration cycle. For that reason, the device left SUT laboratory and will be modified at FrostX workshop, where high-class Endress+Hauser sensors will be installed in the refrigeration cycle.
