Abstract:
This paper is the outcome of students'project guided by the author. An attempt has been made to design and develop a solar still for rose production in India. This unit has the following features:i) possibility of tilt adjustments to suit different altitudes of sun,ii) specially designed steep basin for conveniently keeping the rose petals and water in an inclined position and iii)cover which can be opened to facilitate the cleaning operations. This unit supplied 3.7 litres of rose water in three days during winter in Madras, in India. The sunshine and solar radiation particulars of Botswana are shown to indicate that a better climatic conditions prevail here for a higher production rate.
