China Suppliers - Jiangsu Zongheng ZXG Tube Bundle Dryer Factory for Efficient Low-Oxygen Indirect Steam Drying
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.

Special Features
- Indirect heating, no contact between product and heating medium
- Saturated steam of 6 bar / gas heating source
- Low oxygen drying
- Compact construction

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 requirements.

Frequently Asked Questions
❓ How does the ZXG Tube Bundle Dryer work?
The ZXG Tube Bundle Dryer uses a steam-heated tube bundle that slowly rotates inside a stationary housing. The product is conveyed axially through the dryer, elevated by shovels along the circumference, and trickled back through the tube bundle into the discharging trough. Drying occurs both by 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 is also available as an alternative, providing flexibility to suit different facility energy configurations.
❓ What types of materials can be dried in a ZXG Tube Bundle Dryer?
The dryer is suitable for a wide range of materials including granular and slightly adhesive products. Typical applications include maize germs, maize fibres, maize gluten, spent grains, rapeseed, potato fibre, bone meal, feedstuff yeast, wood chips, and various chemical granulates.
❓ What certifications does the ZXG Tube Bundle Dryer hold?
The ZXG Tube Bundle Dryer holds CE certification compliant with the Machinery Directive, Low-voltage Directive, and Pressure Directive. ASME design and manufacture are also available upon request for projects requiring North American standards.
❓ What is the available size range for the ZXG Tube Bundle Dryer?
The ZXG series ranges from ZXG-80 (80 m² drying area) up to ZXG-1500 (1500 m² drying area), covering a wide spectrum of production capacities. Each model is customized in tube spacing, tube diameters, and shovel configuration to achieve optimal drying performance.
❓ Can the ZXG Tube Bundle Dryer handle slightly adhesive products?
Yes. The ZXG Tube Bundle Dryer is equipped with a specially developed recirculation system that enables it to effectively dry slightly adhesive products in addition to standard granular materials, making it highly versatile across multiple industries.
