Advantages of infrared heating in drying tunnels:
Efficient heating speed:infrared halogen heating heat bulb lamp can directly transfer heat to the material without heat conduction or convection through an intermediate medium. This allows the material to absorb heat quickly and the water evaporates faster. For example, in food drying tunnels, for some vegetables with high water content, such as cucumber slices, infrared heating can shorten the drying time from several hours in traditional heating methods to tens of minutes, greatly improving the drying efficiency.
Uniform heating effect: By reasonably arranging infrared heat element, relatively uniform heating can be achieved in the drying tunnel. The position, number and angle of the heating lamps can be adjusted according to the shape, size and drying requirements of the material. For example, in a wood drying tunnel, for wood of different lengths and thicknesses, by optimizing the layout of the ir infrared heater heat lamp, all parts of the wood can receive uniform infrared radiation, avoiding local overheating or uneven drying, thereby improving the drying quality.
Good energy utilization efficiency: Since Infrared Quartz Heating Halogen Lamp is direct radiation heating, heat loss is relatively small. Compared with traditional hot air drying tunnels, infrared heating drying tunnels have obvious advantages in energy utilization. In some industrial drying applications, infrared heating drying tunnels can save 30% – 50% of energy and reduce production costs.
Protection of material quality: Infrared heating temperature rises quickly, but if properly controlled, it can avoid long-term high temperature damage to material quality. For heat-sensitive materials, such as certain pharmaceutical raw materials and fine chemicals, the application of infrared heating in drying tunnels can complete drying in a shorter time, reducing the composition changes and color changes caused by long heating time, which is conducive to maintaining the original quality of the material.
Application Cases
Food Drying Tunnel: In the food processing industry, many foods need to be dried, such as dried fruits, dried vegetables, and dried meat. Taking the production of dried apples as an example, the cut apple slices are placed on the conveyor belt of the infrared heating drying tunnel. As the conveyor belt moves, the apple slices pass through the heating zone in turn. The infrared rays emitted by the halogen glass replacement parts evaporate the water in the apple slices quickly, while retaining the nutrients and flavor of the apples. Moreover, the continuous operation mode of the drying tunnel can achieve large-scale production and improve production efficiency.
Ceramic green body drying tunnel: In ceramic production, ceramic green bodies need to be dried after forming to prevent problems such as cracking during the firing process. Infrared heating drying tunnels can provide a fast and uniform drying environment for ceramic green bodies. By adjusting the power and position of the infrared halogen heating heat bulb lamp, the moisture inside and outside the green body can be ensured to evaporate evenly according to the size and shape of the ceramic green body. In this way, the quality and yield rate of ceramic products will be improved in the subsequent firing process.
Textile drying tunnel: In the textile printing and dyeing industry, fabrics need to be dried after printing and dyeing. The infrared heating drying tunnel can quickly dry the fabric without causing wrinkles in the fabric. The fabric passes through the infrared heating zone at a uniform speed on the conveyor belt in the tunnel, and the infrared rays emitted by the infrared quartz glass halogen bulbs evaporate the moisture in the fabric quickly. Due to the radiation heating, the fabric fibers are not impacted by strong airflow, and the flatness and softness of the fabric can be maintained.
