The experiment was carried out at Department of Renewable Energy Engineering, College of Technology and Engineering, Maharana Pratap University of Agriculture and Technology, Udaipur to study drying of aloe vera gel (Aloe vera barbadensis miller) in solar cabinet dryer. In the present investigation, aloe vera dried in solar cabinet dryer and compared with open sun drying method. Results showed that moisture content, average drying rate in aloe vera gel as 98.45 per cent (wb) to 8.82 per cent (wb) and 1.47, 1.34 and 1.19 g/100g dm/ h to 3.96, 2.7 and 2 g/100g dm/ h in solar cabinet dryer and in open sun, respectively. The moisture diffusivity varied in the range of 1.59×109m²/s to 1.54×109 m2/s in open sun drying and 1.88×109 m2/s to 2.56×109 m2/s in solar cabinet drying of aloe vera samples. Among the twelve thin layer drying model, best-ranked model applicable to the variation of moisture ratio with drying time of aloe vera samples in open sun drying were two-term model whereas in cabinet drying was diffusion approach model.
