ABSTRACT
Food preservation is very essential for human survival, since most food items are perishable and as such can get damaged if they are not properly preserved. There are different ways of preserving food items such as processing the food to a finished food and package it, putting the food items in the fridge, drying either slowly or quickly using fire or smoking. Sun has been utilized for some time now for different applications including cooking, heating, power generation as well as drying of food items. The research is to fabricate a multipurpose solar drier, so as to reduce the issue of wastage of food products through decay and attack by animals. This will go a long way to eradicating or reducing the wastage the farmers normally encounter when fresh food is to be kept for more than two days. The component has the capacity to rapidly eliminate moisture contents from fresh Agricultural produce in order to save them from damage. The result of the fabrication show that the starting temperature of the atmosphere was 38oC, while in the direct chamber was 45oC and 40oC in the indirect chamber and the end temperature was 40oC for the atmosphere, 45oC for the indirect chamber and 52oC for direct chamber. The highest temperature is 45oC for atmosphere and 63oC and 74oC for the indirect and direct chamber respectively. The weight of the content outside reduced from 20kg to 15.70kg with efficiency of 21.5%, in the direct chamber it reduced from 20kg to 10.40kg with efficiency of 48%, while in indirect chamber it reduced from 20kg to 12.20kg.
