Precision Controlled Natural Gas Drying Oven for High-Quality Pulp Molded Products
Composition of Production Line:
This advanced system features a multi-zone insulated structure, high-efficiency natural gas burners with modulating valves, precision PID temperature controllers, industrial humidity sensors, variable frequency drives on all fans, a heat recovery unit, and a sophisticated PLC with data logging for full process traceability.
Product Description:
This precision natural gas drying oven offers unparalleled control over the drying environment. It precisely manages both temperature and humidity levels throughout the drying tunnel, preventing case-hardening (surface crusting) and ensuring moisture is gently and uniformly removed from the inside out. This results in superior product quality, reduced warping, and higher yields for premium products.

Application:
Perfect for premium and high-value pulp molded products where consistent quality and precise moisture content are critical, such as premium food service packaging, medical packaging, and products with complex geometries prone to warping.
Customization:
The system is highly customizable. The control logic, sensor placement, data reporting format, and level of automation can be tailored to integrate with your factory's quality control protocols and MES system.
Feature:
- Precision Humidity Management: Actively controls the drying rate by managing humidity levels, which is critical for product integrity.
- Modulating Burners: Provide smooth, precise heat input, improving temperature stability and fuel efficiency.
- Process Traceability: Records all drying parameters (temp, humidity, speed) for each batch for quality assurance and troubleshooting.
- Superior Product Quality: Minimizes defects like warping, cracking, and inconsistent curing.
- Support and Services:
Dedicated process engineering support to develop drying profiles, remote system health monitoring, software updates, and advanced training for your technical staff.
Packing and Shipping:
All components are packed to international standards. Sensitive control instruments and valves are shipped in separate, protective packaging.
FAQ:
- Q: Why is humidity control important in drying pulp molding?
- A: If the air is too dry and hot, the surface of the product dries too quickly, forming a hard shell that traps moisture inside (case-hardening). This can later lead to blistering, delamination, or mold growth. Precise control allows for a customized drying curve that gently removes moisture throughout the product.
- Q: Can we access the drying data remotely?
- A: Yes, that is a core feature of this system. You can view real-time performance and historical reports from anywhere, providing invaluable data for process optimization and quality audits.
