Abstract
Solar drying is implemented in the agricultural sector since the stone ages. But as the commercialization of the agricultural sector took place and the production has increased at a tremendous rate. Due to this phenomenon, efficient and fast solar drying techniques are needed by the farmers to dry a lot of crops, fruits and vegetables. The efficient solar drying techniques has been found out and implemented by using different shapes of dryer, using different materials etc. The change in vacuum pressure of the air present inside the dryer also facilitates the enhanced drying of the products by removing moisture at higher rate. This research work deals with the analysis of solar dryer and effect of change in vacuum pressure of the air inside the dryer on the drying speed and quality. In this a grape dryer is used which is connected to the vacuum pump, and the vacuum is changed using this pump while grapes are dried up to 25% moisture content. The results obtained show that the vacuum pressure does have a positive impact on the drying performance and as vacuum pressure increases drying time decreases.
