China Suppliers Factory: Jiangsu Zongheng ZXG Tube Bundle Dryer for Safe, Efficient 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.

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 (FAQ)
Q What is the working principle of the ZXG Tube Bundle Dryer?
The ZXG Tube Bundle Dryer uses an indirect heating method. The steam-heated tube bundle slowly rotates inside a stationary housing, conveying material axially through the dryer. Shovels lift the product along the circumference, and the material trickles through the tube bundle, getting dried by contact with the heated tubes and by convection.
Q What heating sources are compatible with the ZXG Tube Bundle Dryer?
The ZXG Tube Bundle Dryer is designed to work with saturated steam at 6 bar as the primary heating source. Gas heating is also an available option, providing flexibility for different plant configurations and energy requirements.
Q What types of materials can be processed in a ZXG Tube Bundle Dryer?
The ZXG Tube Bundle Dryer can handle a wide range of materials, including granular products and slightly adhesive materials. Typical applications include maize germs, maize fibres, maize gluten, rapeseed, potato fibre, spent grains, bone meal, feedstuff yeast, wood chips, and various chemical granulates.
Q 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 customers requiring North American standards.
Q What drying area range is available for the ZXG Tube Bundle Dryer series?
The ZXG Tube Bundle Dryer series offers a wide range of drying areas from 80 m² (ZXG-80) up to 1,500 m² (ZXG-1500), with main motor power ranging from 7.5 kW to 160 kW, making it suitable for small to very large-scale industrial drying operations.
Q Can the ZXG Tube Bundle Dryer be customized for specific applications?
Yes. Each ZXG Tube Bundle Dryer is customized according to the specific application requirements. Parameters such as tube spacing, tube diameters, shovel positions, and shovel angle steels are all optimized individually. Auxiliary equipment such as fans and cyclones can also be provided to meet specific process requirements.
