In the past, farmers friends buy corn dryer, will give preference to imported products, compared with domestic corn dryer, imports of technology is more advanced, however, in recent years, more and more people are buying domestic corn dryer, imports are fallen by the wayside. Have two reasons, one is because the performance of domestic corn dryer technology has a great improvement in recent years improved, 2 it is domestic corn dryer price relative to the imported product will be cheaper. Now the domestic corn dryer, the overall performance compared with previous years has made great progress, and has also been gradually narrowing the gap between imports, however, the author thinks that, the performance of domestic corn dryer technology has much room to improve, also needs to solve some problems still exist defects, according to the analysis and prediction of professionals, the direction for the future of domestic corn dryer will present the following trend:
1. The existing domestic corn dryer drying process in the future will be perfect the improvement of the step, at the same time, on the basis of the large-scale, domestic corn dryer will be to develop in the direction of automation, including automatic control, automatic adjustment, automatic analysis, etc.
2. Domestic corn dryer should be to develop in the direction of small, multi-function, mobile convenience, simple operation, less investment and can ensure the quality of corn after baking.
3. Most of the drying equipment with hot air recycling function, in the future, the domestic corn dryer are expected to join the function, to reduce heat consumption, improve the efficiency of heat energy.
4. To design a high moisture corn safe moisture machinery, require precipitation rate more than 10%. Therefore, there are two ways: one is to use combined drying method, namely two or more corn dryer combined into a new drying technology, such as using high temperature rapid corn dryer to wet preheated with low temperature circulation corn dryer drying at low temperature, from the current world corn drying technology development situation, this is a kind of trend; Second is to design efficient corn dryer.
5. Our country existing corn dryer mainly small and medium-sized, should be gradually to standardization, large-scale development. Due to the large corn dryer with low heat consumption and low operation cost, therefore, should focus on developing capacity in more than 50 t/h model, in order to improve production capacity.
6. Study for coal-fired energy model is still the main direction of future domestic corn dryer, and at the same time should also explore new energy available models, such as microwave energy, solar energy, etc.
