Corn seed processing features

Compared with other field crops seeds, corn seeds in the stripping process , choose ear , ear drying, threshing and other processes is clearly its unique . In particular, the special election process ear of corn seed , in the case of machinery and equipment are widely used in other processes , the basic realization of the main processes are automated, the main work of this step is to rely on a lot of artificial completed . It is the largest artificial corn Ctgrain Seed Processing Plant in a process consumed . By removing the artificial ear disease , infestation ear , immature ear , shaped ear , not the net spike strip , can significantly improve the quality of seeds ( including seed purity ) , reducing the role of the difficulty of subsequent processes ; ear of corn seed drying ( generally not bake grain ) corn seed processing foreign another significant feature . Corn seeds mature, regardless of how high moisture content , how appropriate ambient temperature , all the way to the ear batches sent to processing plants, as soon as possible into the drying chamber drying. Is generally used 72 hours or so quickly make the ear from about 35% moisture content , down from 12.5% ​​to 13% of the safe storage moisture. After drying corn seed threshing conducted . Europe has some corn seed drying differences from theory to practice and China . European and American counterparts think , threshing corn seed crushing rate when its moisture content were positively correlated. Particularly , before the water is substantially higher than 12% higher than the 18% moisture so ago, just after the crushing rate is less than 12% moisture when the threshing decrease with increasing water content . The difference between the theoretical results of the final practice needs to be clarified , but the type used in the experiment thresher and thresher different reason , it is possible to make the results appear different. However, if the foreign drying process using ear once understood as excluding energy consumption, simplify the drying process , it seems that it can not fully explain the problem. Corn seed grading multiple stages is a notable feature . The reason, after the first grading seed dimensions are very close , so that the effect of gravity using a machine better selection . Secondly , grading finer the better when using the disc seeder , will help to ensure the accuracy of sowing . Meanwhile , grading finer , more uniform grain , the more beneficial to ensure accuracy when packaging operations . More important reason may be after grading seed , field corn production is more consistent , can improve the efficiency of photosynthesis , thereby increasing corn yields . Therefore , foreign corn seed processing plant on its tire grading is more than the number usually above grade 6 . Another feature is the packaging. European and American companies in the corn seed packaging , has abandoned the simple measurement of the weight of law , but in the main bag of grains , weighing only as a reference. Average corn seed bag 80,000 , roughly the amount of one hectare ; addition, from the process equipment to ensure the seed crushing rate is low like a designer to implement the idea . Ear into the pit from the beginning to the end of the packaging material , from transport to a temporary , always consider how to reduce fragmentation . Such as reducing ear feeding pits ( groove ) depth , extensive use of conveyor belts, open conveyor, ear fabric, seed material are used temporarily blanking buffer devices.
