"Paddy harvests the intensive drying technology and equipment R & D and demonstration" project by Chengdu grain storage Science Institute of the bear, Zhengzhou scientific research and Design Institute, Jiangsu Zhengchang group, Nanjing University of Finances and Economics, Academy of science of national commissariat bureau, China Agricultural University cooperative research and demonstration. Subject integration of high moisture paddy drying technology of two steps, the first step will high moisture paddy rice mechanical drying to about 18% moisture, second steps of in-store drying to safe water; R & D using chimney residual heat recovery technology of high efficiency energy saving drying equipment, research and application of layered ventilation technology, saving drying energy consumption by more than 20%, improves the drying of Cereal Powder quality of paddy of high moisture, for large-scale drying provides solutions. Project development and application of the ventilation of granary wireless control technology, design and development of the control circuit module and a software program, research and development of grain bulk under the special pipe and tube, solves the in-store drying equipment installation labor intensity and moving the inconvenient problem. Subject combination closely, in 13base points to carry out efficient drying and barn slow drying technology application demonstration, economic benefit, social benefit, environmental benefit, achievement promotion application prospect.
