China Suppliers Factory for Jiangsu Zongheng ZXG Tube Bundle Dryer - Efficient Indirect Steam Drying Solutions
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 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 trickles back through the tube bundle. Drying is achieved through direct contact with the heated tubes and by convection.
❓ What materials can be dried using the ZXG Tube Bundle Dryer?
The ZXG dryer is suitable for a wide range of materials including maize germs, maize fibres, maize gluten, spent grains, rapeseed, potato fibre, bone meal, feedstuff yeast, wood chips, granulates, and other granular or slightly adhesive products across brewing, starch, chemical, extraction, and wood processing industries.
❓ What heating sources are compatible with the ZXG Tube Bundle Dryer?
The ZXG Tube Bundle Dryer is compatible with saturated steam at 6 bar as the primary heating source. Gas heating is also available as an alternative, providing flexibility for different industrial setups.
❓ What certifications does the ZXG Tube Bundle Dryer comply with?
The ZXG Tube Bundle Dryer holds CE certification in compliance 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.
