Quick facts
Tetra Pak® Tall Wide Body Spray Dryer is predominantly used for nutritional powder production, such as a full range of infant formulations and other thermoplastic behaving products.
Capacity
From 0.5 to 10 tonnes of powder output per hour depending on product range and concentrate intake.
Applications
Produces nutritional powders, including a full range of infant formulations and other products with thermoplastic properties.
Produce nutritional powders with a highly flexible spray drying system
- Produce high-quality nutritional powders and optimise for the most demanding powder properties
- Customise the design to suit your exact product needs, benefiting from wide flexibility in product recipes, composition and powder functionality
- Benefit from integration in a full Tetra Pak line solution including wet section, evaporation and powder handling
Features
Straight tube air distributor
Straight tube air distributor (STAD) with integrated high-pressure nozzle assembly
- Single or multi venturi air distributor evenly distributes drying air at relatively low pressure drop, minimising electricity consumption
- Modular design enables multiple venturi deployments as dryer capacity increases, ensuring standardised atomisation conditions
- Chamber roof cooling system minimises powder deposits (bearding) and prevents overheating of any deposits that do form
Swivel adjustable lances
Swivel adjustable lances for improved safety
- Easy and accurate process adjustments and enhanced operator safety through short lances and side-mounted placement
- Each air distributor has integrated high-pressure nozzle assembly and optional fines return capability
- Depending on required functional properties, fines separated from exhaust air can be reintroduced in the atomising zone
Tetra Pak® Shaking Bed
Tetra Pak® Shaking Bed for single- and multi-stage drying
- Single- and multi-stage drying of agglomerated and non-agglomerated products
- Allows gentle after-drying and after-cooling of delicate products
- Shaking motion improves air/solids contact for superior mixing and higher thermal efficiency
- Depending on product type, the product passes through a static bed, a well mix shaking bed and plug-flow drying and/or cooling bed
Tetra Pak® Bag Filter
Optimal powder particle separation with Tetra Pak® Bag Filter
- Separates powder particles in exhaust air of spray drying installation
- Dislodges deposits with compressed air and pulses them into fluidising cone
- Filtered air leaves top of bag filter via clean air side and is discharged via exhaust fan
- Designed for maximum product yield, low emissions and competitive total cost of ownership
Options
Open pressure transport
Open pressure transport system for fines separation
- Separates and collects fines present in exhaust air
- Uses conditioned air to convey and cool the fines before separation in system cyclone
- Reduces fines’ exposure to heat, minimising potential product damage
- MPT system conveys fines to atomising zone for agglomeration or fluid bed for production of non-agglomerated product
Dehumidifier
Dehumidification for greater product stability and quality
- Dehumidifier reduces humidity of main inlet air and helps standardise relative humidity of the process air
- Improves product stability and quality
- Reduces fouling and increases stable capacity for higher operational stability

Multiple feed systems
24/7 production with multiple feed systems
- Multiple concentrate feed systems allow concentrate tanks, heaters and high-pressure pumps to be independently rotated and cleaned
- Supports round-the-clock production if desired
- Changeovers of lines feeding high-pressure pumps are by water flushing the feed system – a setup that eliminates product loss
- Post-production line immediately flushed and cleaned when product diverts to clean high-pressure concentrate line
Spray monitoring system
Spray monitoring system for full control
- Continuously monitors spray pattern of high-pressure nozzles to ensure safe spray drying and prevent nozzle leakage or product build-up on nozzle tips
- Consists of camera system connected by fibre optic cable to a PC monitor
- Supports maximum air inlet temperature of 280˚C
- Camera cooling system at top of drying chamber
