Stordworks Tube Bundle Dryer is an indirect steam heated dryer and is well known for its efficient and gentle treatment of products.
By using steam as indirect heating media, customers are flexible in the choice of their energy source to produce steam.
PRINCIPLE OF OPERATION
The steam heated tube bundle rotates in a fixed housing and conveys the product to be dried axially through the dryer. Shovels transport the product along the circumference of the housing, where it falls through the heated tube bundle for each rotation.
The economic and gentle drying is achieved by contact with the tubes and convection. The heating medium is typically saturated steam appr.5-6 barg, solutions with lower steam pressure are available.
BENEFITS OF Tube bundle DRYERS
- 1.Drying with indirect steam and sweep ambient air, means no pollution to your product.
- Low installation costs through modular design and pre-manufacturing.
- Gentle drying not harm the products.
- Low energy consumption in the range of 1,1 to 1.3 lbs of steam/lbs of water evaporation.
- Optimal sealing and insulation secure high wet-bulb temperatures and optimize energy recovery up to 67% in further processes (e.g. evaporator).
- Safe process: minimized oxygen content ensures the lowest explosion and fire risk. ATEX design if required.
- Clean and environmentally friendly: Integrated dust collector to minimize dust emissions to the atmosphere – closed-loop systems are also available.
- Closed gas-tight system as well as design for drying below atmospheric pressure are possible.
FIELDS OF APPLICATION
Tube bundle dryers are used for various products, preferably when steam should be utilized as heating media and lowest temperatures are required.
Stordworks tube bundle heat exchangers are employed in a wide range of applications as dryers, conditioners or desolventisers. Both granular as wells as slightly adhesive products can be dried in a tube bundle dryer. To be able to dry slightly adhesive products, the dryer is equipped with as specially developed recirculation system.
To achieve an optimal operating behavior, each dryer is customized, e.g. the spaces between tube and tube diameters, shovel positions and filling levels inside the housing etc. are selected and adjusted to an optimum.
According to requirements, it may be a useful supplement to run drying tests with the product to be dried - either on the customer’s site or in a lab.
