Abstract: Solar drying is regarded as the most convenient technique of conservation in the preservation field. This paper aims at studying the impact of drying parameters on the dandelion root as well as analysing the interactions between the factors based on factorial experiments, statistical calculations, and ANOVA analysis. The drying of the dandelion plant process was carried out in an indirect solar dryer with a separate solar collector and a drying unit. The outcome is a model that helps to analyse the impact of drying parameters on the response, which is the time of drying. Determining the factors that affect the response is a prerequisite step so that we can analyse their influence on the drying time and on the quality of the sample.

Keywords: solar energy; dandelion root; drying parameters; semi-empirical models; analysis of variance; ANOVA; full factorial design.
