Design and Analysis of Absorbing plate of Hybrid Type Solar Dryer for drying Ginger and Tomato

Abstract

The solar drying technology is a quick and easy process of drying of food product in a
hygienic way. The present investigation represents a development of hybrid type of solar dryer
which can be used both in day and night time. The main objective of this research to do
simulation for Steady state thermal analysis of absorbing plate (corrugated Aluminium sheet, 5
mm thickness) and various results obtained like temperature variation, total heat flux, directional
heat flux by using Ansys software. The maximum range of temperature, total heat flux variation,
directional heat flux generated were 96.83°C, 0.14 W/mm2 and 0.081605 W/mm2 respectively
.The boundary condition such as the amount of heat flow conducted i.e. 10660 watt in the bottom
face of absorbing plate and convective heat transfer coefficient as 100 W/mm2 0C were assigned.
The food products such as ginger and potato were tested for drying and temperature profile at
various point were obtained.
