    DEVELOPMENT AND PERFORMANCE STUDY OF A CABINET DRYER
    (HAJEE MOHAMMAD DANESH SCIENCE AND TECHNOLOGY UNIVERSITY, DINAJPUR., 2012-06) ZUBAIR, MD. IMTEAJ; Prof. Dr. Md. Kamal Uddin Sarker
    Moisture content is an important factor in the preservation of grains. If the moisture content is above the safe moisture level at suitable temperature, the grains are in the risk to be attacked by different types of insects and microorganisms and loss of value due to spoilage. Due to the lacking of drying facilities, a huge amount of produced grains are lost every year in Bangladesh particularly in the rainy season. Keeping the problem in mind a cabinet dryer was developed in the Power and Machinery Laboratory, Faculty of Agro-Industrial and Food Process Engineering, Hajee Mohammad Danesh Science and Technology University, Dinajpur. The dimensions of the dryer are 1.52m long, 0.61m wide and 1.52m high. An automatic temperature control system was incorporated in the existing dryer by using thermocouple, temperature controller and magnetic contractor to control the quality of the grain. This system maintains the safe drying temperature level for grain. There are four trays placed one over other inside the dryer. The grain holding capacity of each tray is 10kg of fresh paddy. About 40kg paddy was dried per batch at the temperature 43-44°C in seven hours period from the initial moisture content of 25.2% to final moisture content of 13.6% (wb). The electricity cost for drying per kilogram of paddy was Taka 3.74.
