In this study, drying tests on fresh cheeses were carried out in a cold store equipped with a Munters MG90 dehumidifier that controls the humidity of the room air. In this system, the condensation/drainage stage is omitted since the humid room air is directed out of the cold store (process air) and the dried air is introduced by the dehumidifier inside the cold store. Eight air temperature probes were introduced in the store; two probes (HOBO U12-012, 1) HOBO – Onset Computer Corporation, Cape Cod, MA, USA) were also introduced and used to measure relative humidity and temperature together with an anemometer to analyse any changes in thermal and fluid dynamics in the cell environment. COMSOL multiphysics software (Comsol Group, Stockolm, Sweden) was used to simulate the store environment based on the finite elements method. This allowed us to compare and discuss the experimental data collected and the results obtained by the thermo- fluid-dynamic simulation.
