Product Profile of Industrial Grade Vacuum Paddle Dryer

Industrial grade Vacuum Paddle Dryer is utilized in varied industries to extract and obtain dry powder either from solutions or wet cake. The Paddle Dryer involves a closed system wherein hot water, steam, or hot fluid is used as a heating medium within the jacket, in the hollow paddle as well as in the hallow shaft. The Paddle Dryer includes vacuum pump, condenser, receiver and dust collection unit. Industrial grade Vacuum Paddle Dryer is provided with a hollow rotating agitator shaft that imparts heat to the product and scrapes the shell wall tumbles.

Key Features of Industrial Grade Vacuum Paddle Dryer

• Common base frame is unique to this system
• Drying optimization is a process that is carried out by means of external and internal heating. External heating is generated through jacket or limpet coils, while internal heating through a hollow shaft, along with a set of hollow paddles. These hallow paddles are equipped with scrapers that have very low gap from wall in order to maximize heat transfer. Scrapers move material to all parts of the dryer and additionally help in discharging the material
• 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
• The large heat transfer area available on the wide paddles and hollow shaft enable and equip maximum heat transfer efficiency to the product
• Mechanical seals at shell ends/ stuffing box
• The vessel is well 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. So as to remove the condensate formed by steam heating in the hallow shaft, special rotary joints are also designed to introduce heating media in the hollow shaft
• Filter is very efficiently used to arrest valuable product carried away with the vapours in a filter bag. The arrested product particles are thrown back into the dryer by reverse flow of pulsating air. Generally, the product filters are heated to avoid condensations of vapours in the filter bag
• 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/ limpet coil
