Development And Evaluation Of A Fire In Tube Boiler For The Dehydration Of Maize Product

ABSTRACT  Majority of farmers in Nigeria harvest a large proportion of maize under conditions of high  humidity, and sadly enough, they lack equipment for drying the grains. The farmers store the  grains at conditions of high moisture and humidity which results in growth of organisms that  cause deterioration. One of the most important operations carried out for the preservation of  maize is dehydration. It helps to reduce the moisture content of the grains to a level in which  spoilage...
