The Research Of FGJ90Flat Dryer

Agricultural product drying is one of the most complex and important technology in the world. Because this kind of drying is a transfer phenomenon that mass, heat are happen in solid medium at the same time, and it is very difficulty to describe in the method of maths and the results often is invalidate. A.S.Mujumdar who is a famous researcher of drying said that drying is the mixture of science, technology and art.The study of dryer is the main issue in drying process of agricultural product and playing a starring role. The agricultural product itself contains more water, if not removed in time by dry processing, it was easy to cause serious mould. The principle of flat dryers is use high temperature steam through the heat transfer, the heat conduction in low temperature, makes the temperature rise of flat plate, when the material in the drying flat plate for step by step a relative motion, can achieve the purpose of dry material.The existing fuel flat drying machine usually with chain and conveyor belt transmission way, and heat transfer of air heat utilization rate is not high, in the process of the in homogeneity of the heat transfer, etc may have charring phenomenon to appear, and now the technical parameters of the dryer for oil drying no unified standard. In advanced technology at home and abroad on the basis of the dryer, through technical innovation and improvement of process, ameliorate the drying uniformity and drying benefits this paper is mainly for the stability of the transmission oil flat dryer, the dryer efficiency of heat energy, oil in the movement condition climb and heat conduction doubled in the fuel efficiency of heat absorption in analysis and improvement optimization. Improve the flat dryer optimization reliable performance and transmission speed stability, oil of drying, without charring phenomenon, air and heat transfer to energy saving goal, in same heat, the optimization design the dryer heat utilization rate is higher.The improved flat dryer to improve the process and adjust the steam flow velocity and pressure etc, so as to improve the heat transfer efficiency, increase the dehumidifying effect. The dryer This paper, from the perspective of economics, the study of technical and economic benefits from, analysis the dryer to improve the process and design plate after the effect, especially to oil as the research object, and study of90m2flat dryer, lists the improved design improvement for oil, before and after the drying. The experimental results show that FGJ90flat dryer can reduced fully the moisture content of rice bran. The storage time reduced to ensure the moisture content, but also ensures good rice bran and improves the quality rate of oil that refined after the press.
