Prospecção tecnológica: secador solar

Abstract

The increasing population growth associated with increased food production brings with it the concern with the environment. Fruit residue enriched and dried can be reused for various purposes, such as feed supplements. There are several drying processes, many can be highly polluting, what else would cause a problem to the environment. In this sphere arise solar dryers, simple and ecological technology. The objective of the research is to make a technological prospecting and raise the number of patents related to these dryers, to discuss the distribution of the product. The methodology used was to perform patent searches on specific databases. After data analysis, it was found that the evolution of solar dryers of patent applications has increased in recent years, possibly following the noticeable increase in global environmental awareness. However, this technology is not yet well developed, probably due to the structural simplicity of such a product and process. It is necessary investment in the development and improvement of dryers, as their importance.
