Steam Heating
Steam enters the preheating cylinder and heats the cylinder from the inside.
Corrugated Cardboard Preheater
Condition the paper before corrugating and bonding.
Prepare the paper for bonding
The corrugated preheater is an important part of a corrugated board production line. It preheats paper and single-faced corrugated board to remove excess moisture. This also helps bring them to a suitable temperature before gluing. This helps improve bonding in the following process.
AGICO PAPER’s corrugated preheater units can be used on 3-ply, 5-ply, and 7-ply corrugated board production lines.
AGICO Corrugator Preheater Unit for Sale
For different-layer corrugator lines, AGICO PAPER provides single-layer, double-layer, and triple-layer preheater units to meet different preheating needs. You can choose the right configuration based on your corrugated board production line structure and preheating requirements.
Single-layer preheater
The single-layer preheater has a single-layer structure and a simple design. It is suitable for production lines with basic preheating requirements.
Double-layer preheater
The double-layer preheater has upper and lower preheating sections. If you need separate preheating for different paper layers, this model is a good choice.
Triple-layer preheater
With three preheating sections, the triple-layer preheater provides a larger heating surface area. It is designed for production lines that require preheating for multiple paper layers.
Working Principle of the Corrugator Preheater Cylinder
The preheating process consists of the following steps:
Heat Transfer to Paper
The paper wraps around the preheating cylinder and absorbs heat from its heated surface. The heat helps remove excess moisture and brings the paper to a suitable temperature for the next process.
Wrap Angle Adjustment
A guide roll adjusts the paper's wrap angle around the preheating cylinder, controlling the preheating area. A larger wrap angle increases the contact area for more intensive preheating.
Why Choose AGICO’s Corrugated Cardboard Pre-Heater
A good preheater can improve the preheating process in corrugated board production. AGICO PAPER’s corrugated preheaters offer the following advantages.
Durable Structural Design
The cylinder surface is finished with hard chrome plating. It can also be fitted with a dished or flat head to help transfer heat more evenly to the paper. The hard chrome surface also helps reduce wear during operation and extend service life.
Flexible Configuration Options
You can choose one or multiple preheating cylinders according to your corrugator line structure and preheating requirements. This allows the preheating setup to adapt to different paper grammages, board layers, and production requirements.
Stable Preheating
The heated cylinder continuously transfers heat to the paper. This helps maintain an even temperature and keep the paper's temperature and moisture content stable. It creates better conditions for the following corrugating and gluing processes.
Precise Preheating Control
The wrap angle can be adjusted electrically. You can adjust it according to the paper condition. This helps control the preheating level and avoid excessive or insufficient preheating.
