The infrared heating tube used in pre-dryer has the following advantages:
1. High efficiency and energy saving
– The infrared rays emitted by the infrared heating tube can be directly absorbed by the material and converted into heat energy, with high heating efficiency. Compared with the traditional heating method, it can reduce the loss of heat in the transfer process, effectively shorten the drying time, and thus reduce energy consumption.
– Its heating method is selective heating, which only heats the materials that absorb infrared rays, and heats less other non-absorbent materials such as the surrounding air, so that energy can be concentrated on material drying, improving energy utilization.
2. Good drying quality
– The infrared heating tube can make the inside and surface of the material absorb infrared energy and generate heat at the same time, realizing simultaneous heating inside and outside, avoiding the situation that the traditional heating method may cause the surface of the material to be overheated and the internal drying to be insufficient, so that the material is dried evenly and the drying quality is guaranteed.
– Due to the fast heating speed and short drying time, it can effectively reduce the problems of deterioration and discoloration of the material due to long-term heating, and better maintain the original quality of the material.
3. Compact equipment
– The infrared heating tube has a relatively simple structure and a small size. It is easy to install in the pre-dryer and can be flexibly arranged according to the spatial layout of the dryer, which can effectively save equipment space and make the structure of the pre-dryer more compact.
4. Environmentally friendly
– The infrared heating tube does not produce harmful gases, dust and other pollutants during operation, does not pollute the environment, and meets environmental protection requirements.
– Compared with some drying equipment that uses steam or fuel as a heat source, the pre-dryer using infrared heating tubes has less impact on the environment and is more conducive to sustainable development.
5. Accurate temperature control
– The heating power of the infrared heating tube can be accurately controlled by adjusting the power supply voltage or controlling the heating time, so that the drying temperature of the material can be accurately controlled.
– This precise temperature control helps to meet the specific requirements of different materials for drying temperature, improve the stability and repeatability of the drying process, and ensure the consistency of product quality.
