About Far Infrared: Drying of Small Parts

Introducing a case where various small parts were mixed and fed into a far-infrared drying furnace!

AMK Co., Ltd. is a company that handles industrial far-infrared heaters, heating devices, and drying equipment. Previously, single parts were flowed into the far-infrared drying furnace, but with the shift to small-batch production of various small parts mixed together, we received reports of undercooked and overcooked parts. Upon investigation, it was found that the mixture consisted of parts with diameters of 50 to 10 mm and thicknesses of 10 to 1 mm, which caused differences in heating rates due to variations in material properties (specific heat differences), weight differences, and differences in the area of the light-receiving surface. As a countermeasure, we need to group parts with the same material or group them based on thickness and light-receiving area, and conduct heating tests to adjust either the transport speed or heating temperature. As a result of these measures, while the workload increased, the advantages of far-infrared heating remained superior to other heating methods. *For more details, please refer to the catalog or feel free to contact us.*
