The size of a freeze dryer is rated in size by the capacity of the condenser to hold ice that is produced in a 24 hour drying cycle (i.e. water from the sample). As a minimum, the condenser capacity must be adequate to handle the total amount of sample volumes in a single batch before de-icing is required.
Vapor collect condenser is one of the key components in a freeze drying system, designed to collect and condense vapors that come from raw product. As per freeze dryer appliion fields, its temperature can be -25C to -80C. The Function As known, freeze drying is a water removing process, fundamental is sublimation.
The freeze-dryer comprises the drying chaer and a condenser where the water vapour is sublimated on some cold surfaces in order to decrease the volumetric flow-rate arriving to the vacuum pump. The pressure in the chaer can be modified either by acting on a valve placed on pump discharge, or using the so called “controlled leakage”, i.e

The gases flow through the vacuum pump but water vapours condense on the coils forming ice layer on coils. The condenser performance is the single most critical factor affecting the efficiency of a freeze-dryer. The efficiency of freeze-dryers is studied by using CFD techniques.
The driving force of freeze drying is the vapour pressure differential between condenser and the product in the drying chaer, not simply the pressure or the flow of gas created by a vacuum pump. Refrigerating systems such as freeze dryers work best if they are run regularly as the refrigerants and system lubricants will pool and settle if
