Cleaning out the impurity from the material is the first step of seed processing commercialization.

The seed purity is the higher the better. The high purity required the processing of great difficult. So it is very necessary to use the seed processing machinery.
　1、The seed impurity is various in shape and property.
　　 The seed impurity is different in size, length, weight, density and color.
The different impurity should be cleaned out in different way and using the different machinery. You should select the seed processing equipment in accordance with the processed impurity.
　2、How to select the seed processing equipment.
　　 Please select the seed processing machinery according to the following rude:
　（1）To clean out the impurity which is smaller in size and lighter in weight, please select the fan selector, which is also the most prevail selector at present.
　（2）To clean out the impurity, which is various in lengths, please select the socket selector.
　（3）After cleaning out by the fan selector and socket selector, the purity of the seed is greatly improved. But there is still some impurity in the seed and its proportion is similar with the proportion of the seed. So we should use the Proportion selector to select the impurity.
　　Before being cleaned out, some seed need to be threshed, grinded and selected the stone. You should select the proper processing machinery.
The seed processing machineries are various in function and complete in variety. The superior processing machinery is applicable in the large scale manufacture. 　
　　The ordinary processing machinery can only select one type of impurity at one time.
　　The secondary seed processing machinery has the advantage of low price, easy to move and operate and high rebound rate. It is popular in the seed processing industry.
　3、How to select the manufacturer?
　　The seed processing machinery is the equipment of the seed industry, the purpose of buying equipment is for better production and management, create the wealth, but not simple direct consumption. The enterprise that you choose should be high specialization,with advanced management,equiped with a good complete set,and the quality of its products is steady.
　　In a word,as to persons who purchase machine, the most important thing is to investigate how about the enterprises'sincerity? At the same time, you should find out how about the technical feature of manufacturer's products,manufacture quality, after-sale service and rational selling price .
　　The competition of market like the competition of battle field.In the market,equipment is weapon. No matter which one equipment you selected might not be the best in the world,still not be the most expensive, but must be the most suitable for you and your enterprises.

　　Our company has a New Product R&D Center, and we have employed 6 senior agricultural machinery engineers with rich experience and 2 electrical machinery engineers,who come from the Provincial Agricultural Machinery Research Institute,to take charge in the R&D of new products.Their efforts make model change more and more soon,heighten the content of technology in product, and accelerate
　　our country's seed machinery industry.Now,3 types of new products are under research and will be put into market soon.
