Yankee Hood System | Tissue Paper Machine
ZhengDing is a professional manufacturer of Yankee Hood Systems for tissue paper machines, providing customized drying solutions for new production lines and existing machine upgrades. Our Yankee Hood System combines high-velocity hot air impingement drying with Yankee cylinder contact drying to improve drying efficiency, increase production capacity, and reduce energy consumption. With optimized airflow distribution, precise temperature control, and efficient heat recovery, the system ensures stable drying performance and consistent tissue paper quality. ZhengDing provides complete Yankee Hood solutions, including engineering design, equipment manufacturing, installation, commissioning, and technical support.
Technical Advantages of ZhengDing Yankee Hood System
1. High Drying Efficiency
The optimized impingement hole arrangement maximizes drying capacity and ensures uniform moisture distribution across the paper web, improving drying performance for high-speed tissue paper machines.
2. Energy Efficiency and Heat Recovery.
Advanced heat recovery system design improves thermal energy utilization, reduces steam consumption, and helps lower carbon emissions and operating costs.
Exhaust Air Control System
The Yankee Hood System incorporates an optimized hot air circulation and heat recovery design to improve thermal efficiency. By recovering waste heat and reducing unnecessary energy losses, the system helps lower steam consumption, energy costs, and carbon emissions.
3. Optimized Exhaust Air Control
The specially designed exhaust air management system maintains balanced airflow and stable operating conditions around the Yankee dryer. Effective control of hot, moist exhaust air helps improve drying consistency and reduce air disturbance.
4. Reliable Structure and Easy Maintenance
The robust hood structure is designed to withstand continuous high-temperature operation and repeated thermal cycles. Its practical, accessible design facilitates routine inspection, cleaning, and maintenance, ensuring reliable long-term performance.

Product Introduction
Zhengding Environment Hot Air Drying Box features a double-layer stainless steel shell filled with 100～150 mm rock wool / aluminum silicate insulation. The temperature rise of the outer shell ≤ ambient temperature +15 ℃. Two types available: 1. Impingement Nozzle Type: Staggered upper and lower nozzles with high heat transfer coefficient, suitable for medium and high basis weight paper. 2. Air Cushion Type: Non-contact support, ideal for thin paper, film and release paper, preventing scratches and sheet fluttering. Applicable width: ≤6600 mm, operating speed: 100～1200 m/min. It delivers uniform drying and stable coating quality. With CFD-optimized nozzle layout and plenum chamber design, the transverse temperature difference is small, effectively eliminating streaks, orange peel defects, color difference and "wet-dry edge" issues.
It is mainly used for water-based or solvent-based coatings applied on the surface of paper, paperboard, film or substrates. By hot air with controllable temperature, wind speed, humidity and airflow organization, convective heat transfer is carried out to rapidly evaporate water or solvents, so as to finally form continuous, flat and firmly adhered coatings.
It supports zoned regulation on demand, featuring remarkable energy saving, strong adaptability, reliable operation and easy maintenance.
