Project Overview
- Asia-Pacific Saide Li is a benchmark enterprise in the high-end cellulose and household paper sectors. This project is being delivered as a turnkey solution by Baotuo Paper Machine. To establish a high-speed, high-quality, low-energy‑consumption household paper production line, the customer has launched a new project to supply the associated hood and hot‑air systems for the paper machine, setting stringent requirements for equipment dryness uniformity, operational stability, thermal efficiency, high-speed compatibility, and long-term reliability.
- The project’s paper machine has a web width of 2,850 mm and a design speed of 1,600 m/min. It is configured to produce high‑grade household tissue, operating under high‑speed conditions that place extremely stringent demands on the system’s compatibility and stability.
- The project achieved a successful first-time startup, with the equipment operating stably and meeting all performance specifications. Drying efficiency, energy consumption metrics, and operational stability all fully satisfy the customer’s stringent requirements.
Scope of Supply
- Zhengding Environment provides project‑specific Yankee hood systems and a complete set of core equipment for hot‑air drying systems, tailored to the operating conditions of a 2,850 mm‑wide, 1,600 m/min high‑speed household paper production line.
- We provide a complete set of system‑specific piping and valve components to ensure unobstructed flow and precise control in the air‑shroud and hot‑air systems, seamlessly adapting to the overall production conditions.
- Equipped with a dedicated control system, it enables precise regulation of the entire equipment’s operating parameters, ensuring automated and stable system operation.
- We offer end-to-end, one-stop services—including equipment installation and commissioning, as well as on-site startup support—to ensure the project is successfully implemented and achieves stable, reliable production.
Core technology
- Based on the paper machine’s web width, operating speed, cylinder diameter, and drying process profile, the air hood outlet temperature, air velocity, and airflow rate are optimized to ensure stable and controllable drying efficiency and final paper moisture content.
- By integrating on-site steam‑heat source parameters with energy‑consumption control objectives, the hot‑air circulation and waste‑heat recovery system is optimized to enhance thermal efficiency, reduce steam consumption, and achieve high‑efficiency, energy‑saving operation.
- Based on the workshop layout, installation conditions, and production environment requirements, the hood sealing, structural integrity, and safety safeguards have been optimized to ensure reliable system operation, convenient maintenance, and long-term stability.
