Drying of fruits / vegetables / Papad in open sun is traditional method of preservation. Quality of open sun dried food products are always concern due to contamination of dirt, dis-coloration and attack by pest (birds/ Monkey etc). To improve quality of open sun dried products and to add commercial aspect to it (as cottage scale processing), experiments were conducted at Vigyan ashram in summer(2015). As a result of these experiment, a low cost solar dryer is developed and tested on various traditional open drying products as leafy vegetables / Amla candy , Papad etc.
