Drum dryers in grain and oil engineering application is relatively common kaolin dryer, with the expansion of production scale, large-scale trends drum dryer obvious fertilizer dryer, which highlights some of the problems and shortcomings of domestic dryer. In this paper, a number of important issues tumble dryer needed to solve large-scale process were analyzed and discussed, and engineering, for example corn oil sauce dryer, drum dryer design and application of the typical problems of practical significance is proposed to solve programs and proposals. About the drum dryer maintenance and repair work we have said before now many, many of which are also on-site technical expertise instance, no matter what kind of protection method is to help users in the proper use of the drum dryer equipment, let maximize productivity, reduce operating costs while ensuring device performance and quality of the premise, to get more revenue. But also can improve the use of the value of the drum dryer equipment, reduce maintenance costs and related expenses.
