Infrared radiation shortens the drying process of paper production
New thesis shows that IR technology can be used to achieve higher drying speed and to study the drying behaviour of individual fibres.The drying process is responsible for a great share of energy used in the paper machine, especially when it comes to premium tissue products such as toilet and kitchen towels. The dewatering is then performed by through air drying technique (TAD) which provides better absorption and softness. A new thesis now shows that supplied energy via infrared radiation increases the drying rate and reduces the need for fossil fuels. Consequently, premium products could
