Solar Dryers: A Brief Review
Аннотация
The rapid increase in global energy demand and the limited availability of traditional energy resources require the development of renewable energy sources. Solar energy is one of the renewable energy sources with a very high potential for use. Accordingly, solar dryers are one of the areas of use of solar energy, which is relevant in issues such as ensuring food security, preventing crop losses, and reducing greenhouse gas emissions. This work provides a short review of research published in the journal Applied Solar Energy (English translation of Geliotekhnika) on solar dryers. A total of 41 articles from 2007 to 2025 (as of May 1, 2025) were found and downloaded in Applied Solar Energy (English translation of Geliotekhnika). After analyzing the annotations of these articles, it was found that 20 articles presented the results of scientific research on solar dryers designed for drying agricultural products based on solar energy. The full text of these articles was analyzed and the main data and experimental results were summarized. The main parameters of solar dryers, such as thermal efficiency, drying efficiency, activation energy, product loading volume, and thin drying model for drying speed, were studied.
