Tube bundle dryers are a safe and reliable product due to their mthod of operation.The steam heated tube bundle slowly rotates in an immobile housing and conveys the product to be dried axially through the dyyer.Shovels elevate the product along the circumference,and then the product trickles,through the tube bundle back into the discharging trough.It gets dried by contact with the tubes and by convection.
Special Features:
Indirect heating,no contact between product and heating medium
Saturated steam of 6 bar/g as heating source
Low xygen drying
Compact construction
Tube bundle constructin made of mild steel or stainless steel
Housing and vapour extraction of stainless steel
CE certification with Machinery Directive, Low-voltage Directive,Pessure Directive
ASME design and manufacture is possible
Tube bundle heat exchangers are employed in a wide range of applications as dryers,conditioners or desolventisers.Both granular as well as slightly adhesive proucts can be dried in a tube bundle dryer.To be able to dry slightly adhesive products,the dryer is equipped with a specially developed recirculation system.
To achieve an optimal operating behaviour,each dryer is customized, such as the spaces between tubes , tube diameters, the position of shovel and shovel angle steels inside the housing ect, are selected and adjusted to an optimum. We also may provde auxiliary equipment ( fan, cyclone) to fulfil process requirement.
