Product Description

The tunnel-type infrared drying furnace is a device used to accelerate the drying of ink after pad printing and screen printing:

Structural composition

• Tunnel-type furnace body: provides a closed space for drying, generally a long channel structure, made of metal material, with multiple layers of reflective plates inside to reflect infrared light and improve the utilization rate of light energy.

• Infrared heating system: is the core part, including infrared heating tubes. Infrared heating tubes can emit infrared rays, which can be absorbed by solvent molecules in ink, causing them to quickly heat up and evaporate to achieve the purpose of drying. The heating tubes are distributed on the top, bottom or both sides of the tunnel furnace to ensure uniform heating.

• Conveyor system: mainly composed of conveyor belts and drive motors. Conveyor belts are generally made of high-temperature resistant materials, such as Teflon conveyor belts, for conveying printed products. The drive motor controls the speed of the conveyor belt to adjust the drying time of the printed product in the furnace.

• Ventilation system: includes air inlet and exhaust port, the air inlet introduces fresh air, and the exhaust port discharges air containing solvent vapor to ensure air circulation in the furnace, which is conducive to the volatilization of solvents and the improvement of drying efficiency.

• Control system: controlled by PLC or intelligent temperature controller, it can set and adjust parameters such as temperature and conveyor belt speed, monitor equipment status, and have fault alarm and other functions.

Working principle

The printed product enters the tunnel drying furnace through the conveyor belt, and the infrared heating system emits infrared rays, which penetrate the ink layer. The solvent in the ink absorbs the infrared energy and the temperature rises, and it evaporates quickly. The ventilation system discharges the air containing solvent vapor and introduces fresh air at the same time. As the conveyor belt moves, the printed product completes the drying process and is output from the outlet.

Features and advantages

• Efficient drying: Infrared heating can quickly dry the ink, greatly shorten the drying time, improve production efficiency, and is suitable for mass production.

• Good drying quality: Uniform heating can effectively avoid the situation where the ink surface is dry but the inside is not dry, ensure the drying quality of the printed product, and reduce problems such as ink fading and adhesion.

• Wide range of applications: It can be used for drying various pad printing and screen printing inks, and can dry printed products of different materials, such as plastics, paper, metal, etc.

• Energy saving and consumption reduction: Infrared heating directly acts on solvent molecules, with high energy utilization rate, which is more energy-efficient than traditional heating methods.

• High degree of automation: It can be used with pad printers, screen printers and other equipment to achieve automated continuous production and reduce manual intervention.

Application︰
In the printing process, the process of the final drying of the ink to the printed matter is very important. We have a variety of means to accelerate the drying of the ink. For example, solvent-based inks can be dried by a tunnel drying oven, and UV inks can be dried by a UV curing machine. dry.
The tunnel drying oven uses a heating tube to generate infrared rays. The infrared rays irradiate the surface of the ink to cause the volatilization of the solvent and the curing of the connecting material. This drying method is very common in pad printing, silk screen printing, especially textile printing. The principle of the tunnel oven dryer is simple, and the structure is not complicated. It has a significant printing and drying effect for plastic printing, toys, gifts, handicrafts and even daily necessities.
