Development and Evaluation of an Infra-Red Dryer for Grape Drying

Abstract

The main objective of the present work was to develop and evaluate a small scale industrial portable grape dryer using infrared radiation heating mechanism with capacity of 150 kg fresh grapes ( type Thompson seedless grapes) suitable for small farms and  rural areas. The dryer was developed, manufactured and tested. A standard dip emulsion pretreatment was used, this pretreatment increases drying rate because of cracks developed on the pretreated grape's surface. The quality evaluation tests showed the advantages of the developed dryer in giving high quality raisin based on the Egyptian Standard of dried grapes (Raisins) No., 285/2005 and in the International standard ISO 21527 (2008). The results also show that, drying grapes with infra-red drying method gives raisin with high safety in terms of microbial infection.
