* The Freeze Dryer also has a better heat transfer rate due to the continuous mixing of the product, resulting in shortening the drying process. | * The Freeze Dryer also has a better heat transfer rate due to the continuous mixing of the product, resulting in shortening the drying process. | ||
* The freezing dryer follows such a freezing step that is simplified because it can be done in the same vessel instead of having a separate freezing unit, which results in easy handling of the product compared to it's predecessor tray dryer equipment. | * The freezing dryer follows such a freezing step that is simplified because it can be done in the same vessel instead of having a separate freezing unit, which results in easy handling of the product compared to it's predecessor tray dryer equipment. | ||
