Product Profile of Rotary Vacuum Paddle Dryer

Rotary Vacuum Paddle Dryer is a cylindrical jacketed vessel with a central agitator having specially designed blades. The Paddle Dryer offers large heat transfer area on the wide paddles and hollow shaft that enable maximum heat transfer efficiency to the product. The Rotary Vacuum Paddle Dryer is provided with a hollow rotating agitator shaft which imparts heat to the product and scrapes the shell wall tumbles. Rotary Vacuum Paddle Dryer is suitable for drying materials which are heat sensitive, as low temperature for drying can be maintained by high vacuum.

Ravi International is the manufacturer of Rotary Vacuum Paddle Dryer. Ravi International offers wide range of equipments for pharmaceutical, bulk drug, cosmetic, chemical, food-beverage and allied industries. Ravi International is an ISO 9001:2000 certified company.

Key Features of Rotary Vacuum Paddle Dryer

• Drying optimization is a process that is carried out by means of external and internal heating
• The large heat transfer area available on the wide paddles and hollow shaft enable maximum heat transfer efficiency to the product
• External heating is generated through jacket or limpet coils, while internal heating through a hollow shaft, along with a set of hollow paddles
• These hollow paddles are equipped with scrapers that have very low gap from wall in order to maximize heat transfer
• There is a hollow rotating agitator shaft that imparts heat to the product and scrapes the shell wall tumbles. This facilitates for maximum heat transfer and discharge product whenever required
• Mechanical seals at shell ends or stuffing box
• The vessel is designed to take temperature stresses in the process of vacuum drying
• Thereby, there is low power consumption with the use of helical bevel gear box
• Special floating bearing design to combat temperature stresses
• User friendly discharge valve design provides vacuum tight closing when the material is processed
• The quick opening facility lever facilities filling of bags when material discharge and packed
• Breaker bars are incorporated in the RVPD to break the lumps when the product forms lumps at some stage in drying process
• Insulation with Cladding will provide on heating jacket or limpet coil
• Suitable for drying materials which are heat sensitive, as low temperature for drying can be maintained by high vacuum
• Low energy consumption compared to any other batch type dryer due to higher differential temperatures
• Higher thermal efficiency
• Almost 100% recovery of solvents
• Heating Temp.: From 30 Degree C to 300 Degree C.
• Limpet coil can be provided instead of jacket if the heating media is fluid.
• Breaker bars of approximately same length as dryer shell can be provided if lump formation is expected during drying
