Seed Cleaning Equipment

Seed Cleaning Equipment, and inclusions using the difference in grain shape, size, density, surface properties and aerodynamic characteristics, the mechanical selection of qualified seed quality. Including Seed Processing Plant and machine selection. Qing kind machine used to remove inclusions from the seeds; selection from seed cleaning machine is used in the selection of miscellaneous post robust full, grain and strong life, if necessary, by the dimensions of the Grain Tester seed grading. Most grain cleaning machinery can also be used to clear the hybrid seed selection and classification.

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.

Seed processing program

The main content of the seed processing : remove all kinds of seed impurities, such as broken stems and leaves, husk , soil particles , stones, sclerotia , seed and other crop seeds waste , improve clarity and seed germination rate ; seed drying , the moisture content reaches safe storage standards ; different size and proportion of seed grading achieve precision sowing ; seed treatment with various types of seed treatment , pest and disease prevention in order to achieve and promote crop growth , increase production purposes , At present, the use of seed coating on the seed coating treatment .
The main content of the particular Seed Processing Plant includes the following three main aspects :
1 , seed cleaning
Seeds and other debris have a variety of characteristics. Seed cleaning is based on their different characteristics to distinguish from each other , such as the difference between the broken stems and leaves, husk , sand and other large and seeds , they can easily be removed from the seeds. But other crops seeds or seeds are sometimes mixed with the seeds similar in some characteristics or appearance , which is difficult to separate , but never exactly the same as all the features between the seed and other inclusions, identify their differences , can be separated.
2 , seeds and dried
Seed drying by drying medium ( air , heated air , gas ) for heating the seeds , the use of water to keep the seeds inside surface diffusion and evaporation of surface moisture constantly achieved .
Evaporation of surface moisture of seeds , depending on the size of the air vapor pressure . The partial pressure of water vapor in the air contents indicates the number of vapor , air and water vapor increases with increasing partial pressure of water vapor in the air . A water vapor partial pressure and moisture content is essentially the same arguments . The water vapor partial pressure between the air and the water vapor partial pressure of the seed surface is poor, dry seeds impetus which determines the size of the seed surface evaporation rate. The pressure difference is large , the rate of evaporation of surface moisture seeds quickly . The main factors affecting dry seeds relative humidity, temperature , air velocity , and the physiological state of the seeds themselves seed chemical composition . Seed drying conditions , and temperature, there is a relationship between the relative humidity and air velocity . The higher the temperature , the lower the relative humidity , the higher the air velocity , the drying effect is better ; contrary, the drying effect is poor.
It should be noted here that, when the seed drying , the seeds must ensure vitality , or even to dry seeds , and have lost the sense of dry seeds.
3 , seed coating
Seed coating is the use of adhesive or film-forming agent , a fungicide , insecticide, fertilizer, plant growth regulators , coloring agents non-seed material wrapped on the outside seeds, the seeds into spherical or substantially maintain the original shape to improve stress resistance , disease resistance , speed germination , seedling promote , increase production and improve the quality of a seed of new technologies.

Advantages of seed processing

In modern agricultural production, Ctgrain Seed Processing Plant by the significant advantages of the following aspects:
First, seed quality has improved significantly, you can reduce the seeding rate, reduce agricultural production costs. By seed processing in general can increase 5% to 10%, significantly increase crop yield per unit area.
Secondly, according to different uses and sales market, seed processing into different levels of standardization and packaging sales, improved seed commodity, can effectively prevent the circulation and sale of counterfeit seeds.
Third, the seed processing, full grain, uniform size, crop growth and tidy, consistent maturity conducive to mechanized planting and harvesting, improve labor efficiency.
Fourth seed processed to remove most of the seeds and coated with pests and diseases, so that the slow release of drug, reducing the amount of fertilizer and pesticide application, and application of pesticides by the open steering concealed spraying, environmental protection.

The basic process of corn seed processing

Ear of corn seeds to harvesting , and larger grain corn seed , which determines has many unique corn seed processing technology. In the United States and Europe , operating corn seeds and other field crops seed company , its size was relatively large, by supporting Seed Processing Plant capacity is also high, and corn seed processing technology countries are basically the same. The typical process is as follows : Ear feed - Mechanical stripping - Select Spike - drying - threshing - Pre-Cleaner - temporary - Cleaning - grading - the proportion of election - Coating - Packaging - storage . Namely: corn seed from the origin of large transport vehicles shipped to processing plants , the use of dedicated access , unloading equipment to make uniform the ear by a belt conveyor to the peeling, ear -election system . Dispensing device by ear , ear into the peeling machine to remove the husk and wool wadding , then entered the election spike units. No peeling machine peeling net return , unqualified ear were excluded . Good ear continues rushed drying systems, by special fabric conveyor circulation to the drying compartment. After the first threshing and drying the ear , after the pre- clearance , and then enter the temporary positions . When seed cleaning grading , first delivered to the temporary storage of wind screen cleaning machine , and then graded by a grading machine , seed grading after entering their temporary positions . After a temporary warehouse pick Gravity selection machine ( gravity -election ) . Excluding selected seed after light gravity , good seed coating machine coating sent again after measuring, packaging , stacking storage, the entire machining process is completed . In order to ensure processing quality , but also the installation process between some random sampling devices , online measurement equipment.
