Title: METHOD AND APPARATUS AND CONTAINER FOR FREEZE-DRYING
Abstract:
A method of drying (sublimation or desorption) a frozen product stored in a container (703), comprising: a) capturing (1401) a thermal IR image of the container wall using a thermal IR camera (701); b) processing (1402) the thermal IR image by calculating temperature values of points located on the outer surface of the container wall; c) calculating (1403) a maximum temperature of the product in the container using a mathematical model that models heat flow and that models progress of the drying process; d) controlling an amount of power supplied to the container based on the calculated maximum product temperature (Tprod_max) and on a temperature safety_margin (Tsm). A freeze drying apparatus for performing said method. A container having a specific shape for use in such a process.
