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 requirements.

❓Frequently Asked Questions
Q1 How does the ZXG Tube Bundle Dryer work?
The ZXG Tube Bundle Dryer operates by slowly rotating a steam-heated tube bundle inside a stationary housing. The product is conveyed axially through the dryer, elevated by shovels along the circumference, and then trickles through the tube bundle back into the discharging trough. Drying is achieved through direct contact with the heated tubes and by convection.
Q2 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 germs, maize fibres, maize gluten, spent grains, rapeseed, potato fibre, bone meal, feedstuff yeast, wood chips, chemical granulates, and other granular or slightly adhesive products.
Q3 What heating sources are compatible with the ZXG Tube Bundle Dryer?
The ZXG Tube Bundle Dryer supports saturated steam at 6 bar as well as gas heating sources. The indirect heating design ensures no direct contact between the product and the heating medium, making it safe and efficient.
Q4 What certifications does the ZXG Tube Bundle Dryer hold?
The ZXG Tube Bundle Dryer is CE certified in compliance with the Machinery Directive, Low-voltage Directive, and Pressure Directive. ASME design and manufacture are also available upon request to meet international project requirements.
Q5 Can the ZXG Tube Bundle Dryer handle adhesive or sticky products?
Yes. For slightly adhesive products, the dryer is equipped with a specially developed recirculation system. Each dryer can also be customized — including tube spacing, tube diameters, shovel positions, and shovel angle steels — to achieve optimal performance for specific product characteristics.
Q6 What is the available size range for the ZXG Tube Bundle Dryer?
The ZXG Tube Bundle Dryer is available in models ranging from ZXG-80 (80 m² drying area, 7.5 kW motor) up to ZXG-1500 (1500 m² drying area, 160 kW motor), covering a wide range of production capacities. Custom configurations are also available to meet specific process requirements.
