The screening effect of Sieving Machine has a very important influence on the quality of seeds and the yield of products.
The application of screening technology in seed processing and production concentrates on two aspects: one is rough screening of large impurities in raw materials by vibration screening, the other is removing unsaturated and dry seed materials by vibration screening, including cleaning of fine sand, clay and other silt impurities in seed raw materials.
1. Application of Sieving machine in Crude Screening of Seed Raw Materials
Seed raw materials come directly from the field, which contain more complex impurities. There are two main types: one is the impurities with larger particle size than grain raw materials, such as corn cob, flax, straw, hemp rope, plastic sheets, etc. The impurity removal is mainly based on the variety and particle size of impurities in seed raw materials. Sieving machine is used to remove impurities from seed raw materials for the first time.
Rough screening does not require high fineness. Screening equipment with large output can be selected.
For example, linear vibration screen:
Screening mesh number is 2-200 meshes, rectangular structure makes throughput much larger than that of circular shaker.
2. Application of Sieving machine in Fine Screening of Seed Material
After removing impurities, the seed raw materials are still mixed with fine silt impurities such as soil and fine sand. At this time, two fine screening is needed. After two screening, the seeds can be weighed and packaged.
Are you demanding high output? Or does it require high accuracy?
Yes!
Then we recommend that you use the ultrasonic sieving machine. The vibration frequency of the ultrasonic generator can reach tens of thousands of times per second, but this does not affect its low-amplitude screening, ensuring that your seeds are intact during the screening process. For materials with a mesh of more than 200 and a lighter proportion, the use of Sieving machine will lead to blockage, while the use of ultrasonic rotating screen will not.
In addition, the ultrasonic self-cleaning network system is also a bright spot.
Can't you be strict with production requirements? Your seed is not that light, either?
Yes!
The screening range of ordinary sieving machine is from 2 meshes to 200 meshes, which can generally meet your needs. Of course, if you have other needs, we also provide customized services! For example, citrate type, gate type, etc.
