The Effect of Selected Factors on Separation Efficiency in a Pneumatic Conical Separator

Abstract: Pneumatic separation is one of the available methods for cleaning seed mixtures. Variously shaped seeds, including spherical (vetch), elongated (wheat), and pyramid-shaped seeds (buckwheat), were analyzed in this study. A seed mixture containing 80% of main crop seeds and 20% of other crop seeds imitating impurities was separated in a pneumatic separator with the shape of an inverted cone in a stream of air. The regression equations describing the separation efficiency of the main crop seeds and other crop see… Show more

“…The key to obtaining high-quality seeds for commercial grain, along with modern varieties and applied technologies for growing agricultural crops, is the immediate, without intermediate storage, postharvest processing of the grain heap coming from the combines with its division into fractions: seed, fodder and unused waste. Such separation of the grain heap at the earliest stage of processing is possible with the use of two-aspiration air-sieve grain cleaning machines implementing fractional cleaning technology [1][2][3][4][5].…”

“…Panasiewicz, et al [8] found that an increase in the moisture content of crushed lupine seeds significantly decreased the separation effectiveness, while an increase in air velocity increased the separation effectiveness. Choszcz, et al [9] identified the effect of factors such as air velocity, moisture and grain type on the separation efficiency of the pneumatic conical separator. In order to increase the test weight and reduce impurities from types of grain product, Crepon and Duyme [10] tested the efficiency of three different types of grain cleaner machine using different grain flow and aspiration rate.…”
