seed cleaner belong to air screen cleaning equipments,this machine use difference of critical velocity 

in vertical airflow between seed and impurities to do the separating.

Firstly,the seed feeding from the bucket elevator(you can change the feeding board to control

the input quantity), the dust and light impurities are removed by aspirator fan.

Second the materials go through the winnowing screen, you can adjust the handle to change

the speed of the air to remove different impurities.

Third the material falls on sieve layers, the big impurities will be left on the first screen and unloaded.

the seed will go to the second layer for further separating by grading sieves. with the three layers of

grading seives,the perfect seed will be grade to big,middle and small sizes. 

seed cleaner can remove light,big and small impurities like grass,straw,branch,leaves,etc.

It has good effection on cleaning seed like grain,wheat,corn,beans,sesame and other commodity plant.

seed cleaner is widely used in seed processing and agricultural products processing industry. 

It is not only can clean the impurities from seed,but also can grading size of seed according to requirement.
