The present invention relates to an improvement in a dryer used for drying grains such as rice and wheat. For example, a dryer used for drying rice uses hot air to blow up the rice and causes the rice to collide with a metal plate at the top, and as the collided rice falls down, it separates the rice that has been sufficiently dried from the rice that has not been sufficiently dried. The method used is to divide it into However, since the grains are hard, the part of the dryer that collides with the grains wears out quickly, and the impact noise is large, so there was a desire to reduce these. Therefore, the present inventor has devised an idea to eliminate the above two drawbacks at once by making the following improvements. That is, the present invention uses an annealed iron-based corrosion-resistant alloy on the grain collision surface of a grain dryer. With this configuration, the life of the dryer can be extended and the noise generated from the dryer can be reduced. The reason is as follows. Grain contains a lot of water, and since this is dried with hot air, the inside of the dryer creates a hot air atmosphere with high temperature and humidity. Therefore, corrosion resistance is required. The grain should be hard and its impact surface should not become punctured even after long-term use. Therefore, by using an annealed iron-based corrosion-resistant alloy, it can withstand long-term use without holes. Annealed iron-based corrosion-resistant alloys have high vibration damping ability and are effective in reducing noise. The iron-based corrosion-resistant alloy used in the present invention preferably has the following composition for the reasons mentioned above. (The following % indicates weight %.) Fe-2~15%Mo, Fe-3~20% WFe-2~
10%Al, Fe-13~30%Cr, Fe-1~30%Cr-0.1
~8%Si, Fe-1~30%Cr-0.1~10%Al, Fe-
1~30%Cr-0.5~15%Mo, Fe-1~30%Cr-
0.5 to 20% W, the present invention is applied to the top grain colliding surface of the grain dryer and parts for sorting insufficiently dried grains from sufficiently dried grains. Good to apply. The drawing schematically shows the dryer of the present invention, (1)
is the surface on which the grains blown up by the hot air collide, and (2) is the plate that sorts out the grains as they descend. The grains also hit this board. It is better to carry out the annealing treatment in an oxidizing atmosphere such as air. The reason for this is that an oxide film of an additive such as aluminum is formed on the surface of the alloy plate, and this oxide further improves the wear resistance of the impact surface. Note that the annealing treatment is preferably performed at 950 to 1200°C, as shown in the following examples. Examples and Comparative Examples Various materials were used to construct the grain collision surface of the dryer, and their effects were investigated. The results are shown in the table.
