Radiation drying apparatus based on a dry target absorption spectrum

Abstract

This invention discloses a radiation drying device based on the absorption spectrum of a drying target. The device includes a radiation source, a housing, and a power supply. The radiation source generates radiation. The housing includes a back plate, side plates, and a support; the side plates have air vents. The support secures the radiation source. The power supply powers the radiation source and controls the switching of individual radiation sources. The design method involves: selecting a suitable radiation source based on the absorption spectrum of the drying target; calculating the required radiation source power and quantity based on the required radiation power density, radiation area, and reflectivity of existing reflectors; designing the housing based on the radiation area and the side length of the radiation target surface; designing the radiation source arrangement; and controlling the switching of the radiation sources via the power supply to change the radiation intensity. This invention enables precise drying of targets and achieves a uniformity greater than 90% and a radiation power density greater than 20 W / cm² for large targets. 2 The radiation distribution is improved, energy consumption is reduced, and drying efficiency is increased.
