As a Seed Air Screen Cleaner Manufacturer, share it with you. Seed processing vehicle machinery is the operation of seed materials on the field. After the clarity reaches more than 90%, it will be further processed toward higher commercialization. Among them, the removal of various impurities in seed materials is the primary link for seed processing to realize commercialization.
People hope that the higher the clarity of the seed, the better, but the higher the difficulty, the more difficult it is. It is like refining pure gold, which is only 99% or more, not 100%. Recognizing and understanding this regularity is necessary for the scientific and reasonable selection of seed processing machinery.
1. Seed impurities are strange and have different properties
According to the geometric size, there are large and small miscellaneous; according to the length, there are long and short miscellaneous; according to the weight, there are light and heavy miscellaneous. Even if they are all light impurities, there are still light weight, light density and relatively light impurities. There are differences in color, which is called heterochromatic grain, which is also a kind of seed impurity classification.
The nature of impurities is different, and the removal methods are also different. Different removal methods inevitably require machines with different principles, which determines the diversity of seed processing machinery. To purchase machinery, if you want to be practical, you must first find out what the attributes of the main impurities are, and strive to be targeted.

2. General principles for purchasing machinery
Seed machinery with different principles focuses on the removal of impurities or functions during seed processing. Among them, there are more principles and types of cleaning machinery, so you should be careful when purchasing them. The general principles are as follows.
(1) If the cleaning is significantly lighter than the good seeds, and the size is significantly different from that of the good seeds, the air-screen cleaning machine should be the first choice. This machine is currently the most commonly used.
(2) When there is a significant difference between the length and the short size of the cleaning, and there are still long or short impurities that cannot be removed after the wind screening process, the socket type selection machine should be tried.
(3) After being processed by a wind-screen cleaner and a pocket-hole concentrator, the clarity has been significantly improved, and the particle size is relatively uniform, but there are still some such as dry corn, insect-eaten kernels, and ear rot kernels ; The shriveled grains, worm sucked grains, and shelled grains in wheat; shriveled grains, smut grains, sprout grains in rice; moth-eaten grains, diseased grains, wrinkled grains in beans... Density impurities are often similar in weight to good seeds, even heavier than good seeds, and cannot be removed by non-specific gravity selection machinery. With the development of the seed industry, the specific gravity selection machinery is becoming more and more popular, and the operation is more difficult than the wind screen cleaning machinery.
