1. Processing and characteristics of oil sunflower seed
For varieties with small grains and not easy to fall, use the machine to harvest and threshing. For larger grains and easy to shatter, use manual harvesting and threshing. After the harvest, the sunflower discs are spread flat on the field. After drying, the grains become small and loose. Then they can be beaten with machinery, wooden sticks or other tools, mechanical threshing may cause the oil sunflower seeds to break or discolor.
After threshing, the oil sunflower seeds are dried and the moisture can below 13%. At this time, the seed coat is hard, its easy to crack use finger press and the seed kernel is more easily broken by hand grinding, then it can be screened and storage.
Most of the oil sunflower seeds are used for squeezing oil. For small-scale oil mills and oil sunflower purchase users, the clarity requirements for oil sunflower seeds are not too high, and some straw and other impurities can be allowed exist.
2. Oil sunflower seed cleaning machine recommendation
The bulk density of oil sunflower seeds is lighter, about 20% of wheat. Most seed cleaning manufacturers use wheat seeds as the standard for processing capacity, therefor, when inquiring about equipment, must inform want to clean oil sunflower seed; If order online, please note the choice of model, since the number on model also based on processing wheat seed.
2.1 Air screen cleaner
The air screen cleaner of our company is mainly based on the 5XZC and 5XF series and there are more than 20 models. The processing capacity of oil sunflower is about 600-3000Kg/h, mainly with 3 or 4 layers of sieves, which can be used to remove light impurities, large impurities and small impurities in oil sunflower seeds. If necessary, while removing impurities, it can also be grading according to the thickness of the oil sunflower seeds.
Take the most popular 5XZC series for example, Its main mechanisms include electric control devices, bucket elevators, vertical wind separation devices, dust collectors and vibrating screens.
2.2 Gravity separator
Some friends often ask they have bought a seed cleaning machine, but think the strawcan’t remove utterly. Can they improve clarity on the basis of the exist cleaning machine?
In this case, we generally recommend add a movable gravity table.
The air screen cleaner mainly cleaning the seeds by external size, and the larger and smaller impurities in the oil sunflower seeds are removed through the limitation of the sieve aperture. But some impurities, such as straw, whose diameter is close to the thickness of oil sunflower seeds, are not easy to remove with a air screen cleaner.
