2. Freeze in Place - The ability to freeze products inside the chamber has its benefits especially for liquid products however this can add up to 6 hrs to the production cycle.
Another benefit is the ability to cool the shelves down to the same temperature as the product when loading from the freezer which eliminates the start of thawing of the of the product before a vacuum is established. The main reason to freeze products solid is to make sure the ice crystals are in a stable form before lowering the pressure in the chamber. If the water molecules are not stable when a vacuum is achieved then they may cause foaming or expansion of products. See this post for more details.
Turn around time from unloading, defrosting and loading a large Cuddon dryer can be as quick as 2 hrs including bring the shelf temperature below 0C.
3. Removable Modules - Although not required every time for cleaning, easily
4. Easy Clean - Requirements from industries sees better design for cleaning of the shelves. The Cuddon module has a flat plate both top and bottom with a gylcol running through the inside. It is easy to use a high pressure hose or water blaster when cleaning the shelves and as everything in the chamber is made from stainless steel, using a cleaning agent or chemical is perfectly fine.
