原文：vacuum shelf dryer vacuum shelf dryers are extensively used for efficient drying in the pharmaceutical, chemical & food process industries. they are very useful for drying temperature sensitive, easily oxidisable, toxic, hygroscopic and expensive dusty materials. the vacuum shelf dryers comprises of the following: vacuum enabled drying chamber with internal hollow shelves. solvent extraction system (optional) with shell & tube type heat exhanger and reciever. vacuum pump with interconnecting pipelines and valves. heating system with water / oil boiler, expansion tank, circulation pump and interconnecting pipelines and valves.
working principle the product laden trays are placed on the shelves provided in the chamber. after which the door is locked. the chamber is vacuumised. heating system is also started. the hot oil / water starts circulating inside the shelves in a serpentine manner. due to this configuration, the heat transfer from the shelves to the trays is quite fast. the heat is transferred to the product from the shelf on which it is placed due to conduction and from the shelf above due to radiation. the boiling point of the product is brought down considerably due to vacuum. vacuum shelf dryers are available in sizes ranging from 6 trays to 96 trays. double door loading for larger models plc based controls for automatic mode.
