China Suppliers: Jiangsu Zongheng ZXG Tube Bundle Dryer - Efficient Indirect Steam Heating Factory Solution
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 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 an immobile housing. The product is conveyed axially through the dryer while shovels lift it along the circumference, allowing it to trickle through the tube bundle. Drying is achieved by direct contact with the heated tubes and by convection.
❓ What materials can be dried using the ZXG Tube Bundle Dryer?
The ZXG Tube Bundle Dryer is suitable for a wide range of materials including maize germ, maize fibre, maize gluten, rapeseed, potato fibre, spent grains, wood chips, granulates, bone meal, feedstuff yeast, and various other granular or slightly adhesive products.
❓ 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.
❓ What heating sources are compatible with the ZXG Tube Bundle Dryer?
The dryer is compatible with saturated steam at 6 bar pressure as well as gas heating sources. The indirect heating design ensures there is no direct contact between the product and the heating medium, making it safe for sensitive materials.
❓ Can the ZXG Tube Bundle Dryer handle sticky or 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.
❓ Is the ZXG Tube Bundle Dryer customizable for specific applications?
Yes. Each dryer is fully customized to achieve optimal operating performance. Parameters such as tube spacing, tube diameters, shovel positions, and shovel angle steels inside the housing are carefully selected and adjusted. Auxiliary equipment such as fans and cyclones can also be provided to meet specific process requirements.
