China Suppliers ZXG Tube Bundle Dryer Factory - Safe & Efficient Indirect Steam Drying for Industrial Applications
Description
Jiangsu Zongheng's ZXG Tube bundle dryers are a safe and reliable product due to their method of operation. The steam-heated tube bundle slowly rotates in an immobile housing and conveys the product to be dried axially through the dryer. 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.

Tube bundle heat exchangers are employed in a wide range of applications as dryers, conditioners or desolventisers. Both granular as well 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 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 etc., are selected and adjusted to an optimum. We also may provide auxiliary equipment (fan, cyclone) to fulfil process requirement.

Frequently Asked Questions
❓ How does the ZXG Tube Bundle Dryer work?
The ZXG Tube Bundle Dryer operates by slowly rotating a steam-heated tube bundle inside an immobile housing. The product is conveyed axially through the dryer, elevated by shovels along the circumference, and then trickles back through the tube bundle into the discharging trough. Drying is achieved through direct contact with the heated tubes and by convection.
❓ What heating sources are compatible with the ZXG Tube Bundle Dryer?
The ZXG Tube Bundle Dryer supports saturated steam at 6 bar as the primary heating source. Gas heating sources are also available as an alternative, offering flexibility for different plant configurations and energy supply conditions.
❓ What types of materials can be dried in the ZXG Tube Bundle Dryer?
The ZXG Tube Bundle Dryer is suitable for drying a wide range of granular and slightly adhesive materials, including maize germs, maize fibres, maize gluten, rapeseed, spent grains, potato fibre, bone meal, feedstuff yeast, wood chips, and various chemical granulates, among others.
