Vibro-pneumatic separator has been applied widely in grain cleaning industries for separating light impurity, gravel and various types of contaminant from grain products. Pneumatic section is utilized as the suction part to separate the light impurity contaminant from the basic product based on the distinction of aerodynamic properties between basic product and impurities contaminants. A multilayer sieves equipped with vibration motor is utilized to separate the grain product from foreign materials other than grains such as sands and pieces of rocks based on the size. To improve the separation efficiency and productivity, several parameters need to be adjusted including the air velocity, vibration frequency and sieve angle. This study attempts to optimize the process parameter of a vibro-pneumatic separator based on the separation efficiency and productivity. An experimental design based on full factorial design was used to adequately adjust the process parameter of a vibro-pneumatic separator including air velocity, sieve angle and vibration frequency on cleaning paddy seeds from different types of contaminants. The effect of factors on each response are analyzed to study the effect of each factor on the desired responses. Multiobjective optimization using a response optimizer is functioned to obtain the optimal setup parameters of a vibro-pneumatic separator based on separation efficiency and productivity. The experiments revealed that vibration frequency was found to be significant for both separation efficiency and separation productivity, while air velocity and sieve angle factors were found to be insignificant for both separation efficiency and separation productivity. An increase in vibration frequency increased the separation efficiency and separation productivity. The statistical results confirmed that R2 of the regression models were 0.78 and 0.89 for the separation efficiency and separation productivity, respectively. According to the multiobjective response optimizer, the optimum setup was at 8 m/s of air velocity, 7 degree of sieve angle, and 20 m/s of vibration frequency. This appraoch enable us to determine the setup of separation machine based on more than one machining parameter using multiobjective approach.

“…Studies aimed at studying the process of grain fractionation are conducted both in the Russian Federation and abroad. In [1][2][3][4], the issues of improving the efficiency of grain and seed cleaning by fractionation on sieves and by the air flow in vertical, inclined and horizontal pneumatic separation channels (PSK) and chambers are considered. Specific technical solutions and their effectiveness are given.…”

The article studies the separation chamber of the pneumatic seed separator including the definition of its key design parameters and determining the best position of its rotary valve edge during wheat seed sorting. The experiment planning method helped us consider the effects the vertical X (x1) and horizontal Y (x2) positions of the rotary valve edge relative to the inlet edge in the separation chamber wall have on the distribution of grain material components in Fractions II and III. We established that it was possible to obtain Fraction II wheat, consistent with RSC commercial reproduction seed purity category with Fraction I seeds consistent with ES elite seed category and permissible loss levels. The required purity of Fraction II is achieved with the separation chamber minimum length of LR.K = 0.55 m and the rotary valve length of LK = 0.28 m. The separation chamber partition edge with the rotary valve is located 0.40 m away from the inlet edge of the front wall and 0.30 m below its level. The highest purity of Fraction II PII = 98.4% is achieved when the rotary valve edge is set in position х1 = -1 (ХK = 0.25 m) and х2 = -1 (YK = -0.10 m). The highest purity of Fraction III with permissible levels of sound seed loss (Fraction IV) is achieved when the outlet edge in the separation chamber wall is positioned at the same level as the inlet edge (the duster inlet height HV = 0.21 m). The results of the research can be used in the development of pneumatic systems for seed-purifying machines.
