Recent research has shown that heat pump drying is an efficient method of drying for drying industries. Applications of heat pump dryers provide high energy efficiency with controllable air flow, air humidity, temperature, and have significant energy-saving potential. They deliver more heat energy during the drying process than the work input to the compressor. There are many traditional methods of drying agricultural produce such as direct or indirect sunlight, wood burning, electrical heating, fossil fuel burning, and diesel engine heating. The heat pump drying method is more advanced than the traditional Nigeria’s industrial and agricultural drying methods. As a result of high increases in fossil fuel prices, failed electricity projects, in Nigeria resulting from the political problems associated with crude oil production, as well as the problem of environmental pollution due to emissions, green energy, energy saving and energy efficiency are imperative.
