The development and implementation of technological lines for cleaning grain and sunflower seed mixture waste using aerodynamic separators, including column-type separators, play an important role in organizing modern solutions for primary grain processing, ensuring effective cleaning and sorting of grain through air flows.
Their relevance is due to low energy consumption compared to traditional mechanical separation methods. They have high productivity, allowing for the rapid sorting of large volumes of grain and seeds. They also demonstrate high efficiency in removing light impurities, dust, debris, and grain admixtures while being characterized by the absence of mechanical contact with the processed material, which reduces the risk of grain damage during processing. Additionally, they can be classified as universal machines since they are suitable for working with various crops (wheat, corn, sunflower, etc.).
Modern enterprises engaged in the primary processing of grain and seeds increasingly implement aerodynamic separators to enhance the efficiency of grain production and comply with international standards.
The experimental research results of the column-type aerodynamic separator presented in this article indicate that the model describing the dependence of the kernel and sunflower seed content in the kernel collection area is significant and adequate. Additionally, equations were derived to describe the relationships between the distribution coefficient and energy consumption based on research factors.
To achieve the efficient operation of the column-type aerodynamic separator, it is necessary to maximize the kernel and sunflower seed content in the kernel collection area, optimize the performance of the vibrating feeder, and minimize its energy consumption. The obtained dependencies were used to adjust the operating parameters of the column-type aerodynamic separator and achieve maximum operational efficiency.
