Using the Infrared Heat for Better Drying and Curing


Want to reduce energy costs, increase productivity and improve product quality? Here are 4 things you can do with infrared to improve the drying process.

A clear drying of the product can only happen with clear temperature control. In this control and user interface for the electronic infrared dryer, the thermocouple control circuits use SCR control components to ensure accuracy.

Drying of coatings or saturating preparations on substrates is considered a common heating method. The uncomplicated process of removing water or other solvents from a coating can consume a large amount of energy. Furthermore, the speed at which the coating dries on the product during its preparation is often a decisive factor in determining how quickly a production line can operate; similarly, product quality is often guided by how smoothly or painstakingly the coating dries. As a consequence, every improvement of the drying process can reduce energy costs, increase productivity and improve product quality. One of the methods of improving the drying process is considered to be the addition or introduction of infrared energy industrial infrared heating systems .

For the process of heating, infrared energy can be generated by electronic or gas-fired infrared heaters or radiators. Each energy source has its own outstanding qualities and defects. Gas infrared systems are usually more expensive to purchase, because of the fact that they insist on security control and gas handling equipment, but they are often more profitable to operate because gas is usually more profitable than electricity. Gas infrared is often considered a good choice for applications that require a lot of energy. Naturally, the product to be heated must be able to withstand heavy steam. These products, like nonwovens and textiles, are examples where gas is often considered a good choice. Vis-a-vis, the electron infrared radiation is probably more suitable than anything else for sensitive substrates such as films and some fabrics, and where « gentle heat » is needed.

Finally, the first thing you can do to increase your infrared drying performance is to make sure that you have selected the right energy key for your application, taking into account the cheapest utility bills for you and the serious investment. There are numerous types of electric and gas infrared heaters, from which it is possible to select the ones that will most likely satisfy your needs. In the process of making a decision to take into account not only the technical properties of equipment and calculations of the thermal load but also how these technological heaters work with your particular product. This is why it is important to do some feasibility studies on the supplier’s pilot lines before making a purchase decision. There is nothing like getting some samples of your actual product to help you decide among the many possibilities.

For efficient drying with infrared radiation than anything else, it is best to put the infrared heaters in an insulated oven shell as in this 8.25-inch dryer. The reflective inner lobe redirects energy to the product where it’s needed, and integrated support legs allow the dryer to settle on the tent frame. Controlled air inlet and outlet speeds drying of aqua-based adhesives on the canvas.
