Sunflower cleaned

Sunflower cleaned several ways: ① the filter is a particle size (width, thickness, length) of the difference between sunflower andimpurities, the impurities separated by the process of the sieve. Screening equipment used fixed sieve, sieve shaker and rotation. Their main work is part of the screen surface, to be a reasonable choice based on sunflower seeds and impuritiessieve particle shape and size. 
② winnowing is to use the difference between the speed of sunflower seeds and suspended impurities, with the wind impurityapproach. The main objective is to clear the winnowing light impurities and dust, while also remove some heavy stones andclods and other impurities, this method is commonly used in such as sunflower and cottonseed oil cleanup. Wind sorter can be divided into two kinds of suction and blowing.

                    
③ magnetic separation method using magnetic force to clear the oil in the magnetic metal impurities. Oil plant commonly usedmagnetic separation device in two ways: permanent magnet permanent magnet drum and barrel. 
④ water, rinsed in water for use in direct contact with the oil, to wash away the oil adhered to the surface of the mortar and a specific gravity sedimentation rate in water of different materials ranging from the principle of the fuel while the gravel, sand,heavy metals, etc. remove impurities, and side by side in the mud can loose the action of water infiltration into the wash water will be fine, the use of water can also be effective in preventing dust flying.
