China Suppliers - Jiangsu Zongheng ZXG Tube Bundle Dryer | Factory-Direct 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
❓ What is the working principle of the ZXG Tube Bundle Dryer?
The ZXG Tube Bundle Dryer operates by rotating a steam-heated tube bundle slowly inside a stationary housing. The product is conveyed axially through the dryer while shovels lift and distribute it across the tube surfaces. Drying is achieved through direct contact with the heated tubes as well as convection.
❓ What heating sources are compatible with the ZXG Tube Bundle Dryer?
The ZXG Tube Bundle Dryer supports saturated steam at 6 bar as the primary heating source. Gas heating is also available as an alternative, offering flexibility for different industrial setups and energy supply conditions.
❓ Can the ZXG Tube Bundle Dryer handle adhesive or sticky products?
Yes. For slightly adhesive products, the ZXG Tube Bundle Dryer is equipped with a specially developed recirculation system that prevents material from sticking to the tubes, ensuring consistent and efficient drying performance.
❓ What industries and materials are suitable for the ZXG Tube Bundle Dryer?
The ZXG Tube Bundle Dryer is widely applied across the brewing industry (spent grains), chemical and plastics industry (granulates), extraction industry (soya beans, rapeseed, sunflower seeds), wood processing industry (wood chips), and starch industry (maize germs, maize fibres, maize gluten, etc.).
❓ 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 manufacturing are also available upon request, making it suitable for international markets.
❓ What is the available size range for the ZXG Tube Bundle Dryer, and can it be customized?
The ZXG series ranges from ZXG-80 (80 m² drying area) to ZXG-1500 (1500 m² drying area), with main motor power from 7.5 kW to 160 kW. Each dryer is customized to the specific process requirements, including tube spacing, tube diameters, shovel positions, and shovel angles, to achieve optimal drying performance. Auxiliary equipment such as fans and cyclones can also be provided.
