China Zongheng ZXG Tube Bundle Dryer - Efficient Indirect Steam Heating | Reliable Suppliers & Factory 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.

Versatile Application: 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.
Customized Optimization: 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
Q What is the working principle of the ZXG Tube Bundle Dryer?
The ZXG Tube Bundle Dryer uses indirect heating: a steam-heated tube bundle slowly rotates inside an immobile housing, conveying the product axially through the dryer. Shovels lift the product along the circumference, and it trickles back through the tube bundle into the discharging trough, being dried by contact with the tubes and by convection.
Q What materials can be processed with the ZXG Tube Bundle Dryer?
The ZXG 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 other granular or slightly adhesive products across industries such as brewing, starch, extraction, chemical, and wood processing.
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 international markets.
Q Can the ZXG Tube Bundle Dryer handle adhesive or sticky products?
Yes. To handle slightly adhesive products, the ZXG dryer is equipped with a specially developed recirculation system, ensuring smooth and efficient drying without clogging or product degradation.
Q Is the ZXG Tube Bundle Dryer customizable for specific process requirements?
Absolutely. Each dryer is individually customized to achieve optimal performance. Parameters such as tube spacing, tube diameters, shovel positions, and shovel angle steels are carefully selected and adjusted. Auxiliary equipment such as fans and cyclones can also be provided to meet specific process requirements.
Q What are the available model sizes and what is the maximum drying area?
The ZXG series offers models ranging from ZXG-80 (80 m² drying area) up to ZXG-1500 (1,500 m² drying area), covering a wide spectrum of production capacities. All models operate with a saturated steam pressure of 0.6 MPa and a calculated heat consumption of 1.4 kg steam/kg H₂O.
