The influence of solar radiation intensity and slime thickness is investigated on the drying process. The greater the solar radiation intensity (SRI) is, the faster the drying indoor air and coal slime are heated, and the faster the drying efficiency is.
The greater the solar radiation intensity (SRI) is,the faster the drying indoor air and coal slime are heated, and the faster the drying efficiency is. As the slime becomes thinner, the internal water diffusion resistance becomes smaller and the drying efficiency correspondingly becomes faster.
For the solar drying technology, the goal is to maximize the use of solar energy and evaporate water at the greatest rate under a certain amount of solar light.
In the realm of materials for solar drying, attention shifts to collectors and other critical components that significantly enhance the efficiency of solar dryers. Performance-enhancing materials and innovative designs are evaluated to assess their impact on drying effectiveness .
