Waste Separation

Разработаны технология и установка для переработки отработанных фильтровальных порошков (ОФП) в кормовые продукты (КП) на масложировых предприятиях после вымораживания подсолнечных масел с целью исключения процесса их окисления. Предложена модернизация ранее разработанной авторами технологии переработки отходов очистки семян подсолнечника (ООСП). Рекомендовано добавление во вторичное масличное сырье (ВМС) из ООСП обезжиренных центрифугированием ОФП. Установлено, что центрифугирование необходимо осуществлять в течение 35 мин при 900 об/мин центрифуги. Определена наибольшая эффективность прессования с экструдированием при добавлении 1–3% обезжиренного фильтровального порошка в ВМС. Установлено максимальное количество обезжиренного фильтровального порошка (10%). Совместная переработка ООСП и ОФП на созданной экспериментальной производственной установке позволила получить КП в соответствии с требованиями нормативных документов на подсолнечный жмых и КП «Подсолнечный» для сельскохозяйственных животных. It has been suggested modernizing the previous technology for recycling of sunflower seed waste, developed by the authors that included waste separation to obtain secondary oily raw materials. A technology and installation has been developed for recycling spent filter powders into fodder products immediately after freezing of sunflower oils at oil and fat plants to exclude the process of their oxidation. It is established that the centrifugation must be carried out for 35 min at 900 rpm of the centrifuge. The greatest efficiency of pressing with extrusion is determined when adding 1–3% of fat-free filter powder to secondary oilseeds. The maximum amount of fat-free filter powder (10%) is set. The co-processing of sunflower seeds waste and spent filter powders at the created experimental operation-performing installation made it possible to produce an experimental fodder product which meets the requirements of normative acts for sunflower seed cake and sunflower fodder product «Podsolnechnyy» used for feeding farm animals.

A feeding trial was conducted to assess the levels of inclusion of high fibre sunflower seed cake HFSSC) protein as replacement for soybean cake protein in the diets of broiler chicken at 0,25,50,75 and 100%. At the starter phase feed intake and feed efficiency ratio were significantly (P<0.05) increased as the level of HFSSC increased in the diets. Weight gain and protein efficiency ratio were however significantly (P<0.05) reduced when over 25% of HFSSC was included in the diet. At the finisher phase same trend was observed except that weight gain and protein efficiency ratio were significantly (P<0.05) reduced when over 50% HFSSC was included in the diet. Significant (P<0.05) differences were in liveweight, plucked and dressing percentages at the starter and finisher phases. Reduction in abdominal fat deposition was obtained at the starter and finisher phases while gizzard weights were significantly (P<0.05) increased. The results of this study show that 50% soybean cake protein in the diets of broiler chicken can be replaced by HFSSC.

Poiseuille Equation

Aiming at cold-pressed oil cakes of linseed and sunflower seed, the pore fractal characteristics of microstructures have been studied. By combining Hagen-Poiseuille equation with fractal theory, a fractal permeability model for oil cake has been developed. The permeability of linseed and sunflower seed cakes under cold-pressed condition has been measured. It was found that the relative average errors are 12.8% and 16.8% for the soybean cake and sunflower seed cake respectively by comparing the result from the model calculation and experiment.

The objective of this study was to investigate the removal of Remazol Yellow dye from aqueous solutions by adsorption on activated carbon prepared by chemical activation of sunflower seed cake. It was found that the carbon content of biomass increases up to 65.12% after activation and carbonization processes. The maximum percentage dye removal was obtained as 82.12% with 0.4 g/50 mL adsorbent dosage at 313 K. The Langmuir model showed the best fit with equilibrium isotherm data. The interactions were evaluated with respect to both pseudo-first-order and pseudo-second-order reaction kinetics. The adsorption process was found to follow the pseudo-second-order model. To optimize the operating conditions, the effects of pH, adsorbent dosage, and initial dye concentration were investigated by full factorial experimental design method; adsorbent dosage was found as the most significant factor with lower than 95% confidence level. The obtained results are very promising since (i) the utilization of sunflower seed cake activated carbon (SSCAC) played a critical role in the adsorption of dye; (ii) sunflower seed cake was an intriguing, low-cost, and easily available material. It can be an alternative adsorbent precursor for more expensive adsorbents used for Remazol Yellow (RY) removal.

For the successful implementation of alternative protein sourcesforbiorefinery, optimization of the process parameters is crucial. Knowledge of the rheological propertiesis necessary for the design and development of appropriate equipment and process calculations.The objective of this research was to evaluate the effect of the following pre-treatments: temperature, pressure andeffect of initial oil content on the rheological properties of sunflower seedcake and larvae tissue. The rheological behavior of two protein sourceswas determined by using a rotational viscometer with a hydraulic system and thermostatic bath attached to the equipment. Using the mathematical apparatus and experimental data it was observed that the plastic viscosity of the sunflower seed cake corresponded to the viscosity of the vegetable oil, which confirmed the Bingham rheology assumption put forward in this work. For the larvae mass, a Hershey Buckley fluid model was proposed.A positive linear relationship was found for pressure and a negativelinear relationship was found for the oil content of the sunflower seed cake and larvae tissue on shear stress.
