The analysis of statistical data showed that a large amount of plant waste is generated annually in oil and fat production plants, which must be processed and reused. The paper analyzes the problems of reusing sunflower oil production waste, which is characterized by a relatively high energy value: 1 ton of plant waste is equivalent to 0.625 tons of conventional fuel. According to the mathematical estimation, the actual total amount of impurities is 7.29%, in which major impurities constitute 25.7%. Studies have shown a high probability of oil – containing impurities – 37.25%. Therefore, it is recommended to process such impurities into fuel briquettes and technical oil to increase the profitability of sunflower oil production. For example, at the annual load of technological equipment of the Melitopol Oil Extraction Plant, in 250 days, at a daily processing capacity of 550 t˙day-1, an annual profit of 560,000 EUR is obtainable from the sunflower grain impurities processed into fuel and technical oil.

“…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].…”

The paper provides a review of fractional technologies developed by the authors, allowing to divide the grain heap coming from combines into 3 fractions: seed, fodder and unused waste. They are based on the use of two-aspiration air-sieve grain cleaning machines. The authors have developed a line of grain cleaners OZF-50/25/10 and OZF-80/40/20. Their productivity in terms of preliminary cleaning is 50 and 80 t/h, primary cleaning productivity is 25 and 40 t/h and secondary cleaning productivity is 10 and 20 t/h, respectively. The machines use an improved two-aspiration system with the ability to independently adjust the speed of air flows in the channels (patent No. 2298441), a new design of a sieve mill with a two-tier arrangement of sieves and setting in each tier sequentially two (at OZF-50/25/10) and three (on OZF-80/40/20) sieves. The mills implement a new sieve arrangement scheme (RF patent No. 43798), as well as original devices for a ball sieve cleaner and a pneumatic separation channel for the second aspiration. These devices make it possible to obtain the required quality of sieve cleaning and to isolate biologically defective grain in the pneumatic separation channel of the second aspiration. The separator for secondary cleaning of seeds SVS-30 is designed for the preparation of seeds of grain, spike, leguminous, industrial and oil crops when implementing fractional technology during post-harvest processing. Like all machines for secondary cleaning of seeds, the pneumatic system of the separator has two pneumatic separation channels for pre-screening and post-screen cleaning. A distinctive feature of the pneumatic system of the SV-30 separator is the consistent use of the same air flow in both aspirations. Fractional technology for processing grain heaps, implemented on an air-sieve separator, will increase the cleaning performance by 1.5…1.8 times with a minimum amount of mechanical stress on the seeds.

“…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.…”

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.
