Воронежский государственный университет инженерных технологий, пр-т Революции, 19, г. Воронеж, 394036, Россия Реферат. В статье разработана и спроектирована малогабаритная линия по переработке зерна сафлора, в которой использовано оборудование повышенной эффективности, реализующее прогрессивные процессы с применением современных физических методов обработки. Данная линия включает в себя ковшовый элеватор (нория), приёмный бункер, воздушно-ситовой сепаратор, промежуточные бункера, триера (овсюгоотборник и куколеотборник), камнеотделительную машину и сепаратор для выделения прицепника широколистного, шнек, промежуточный бункер, шелушильная машина, маслопрессы, устройство для осаждения масла (отстойник), насос, рамный фильтр. Исследован процесс обрушения на шлифовальной экспериментальной установке, в которой разрушение покровного слоя оболочки происходит за счет того, что напряжение на сжатие в зоне воздействия превышает предел упругой деформации оболочки зерна. Проведен ситовой анализ, в результате которого был изучен гранулометрический состав подаваемого на прессование частиц семян сафлора, при этом для характеристики гранулометрического состава сырья, состоящего из частиц неправильной формы, использовали понятие эквивалентный диаметр. В результате проведенных экспериментов была получена зависимость эквивалентного диаметра частиц от диаметра сит. Так как на степень отжима семян сафлора огромное влияние оказывает влажность исходного продукта, поэтому были проведены экспериментальные исследования прессования с различным влагосодержанием семян, а также с добавлением лузги. Из анализа графических зависимостей был установлен диапазон оптимальной влажности семян сафлора 8,5-10%, обеспечивающий наименьшую остаточную масличность и, следовательно, наибольший выход масла. Также удалось значительно повысить эффективность отжима масла путем добавления в семена сафлора предварительно обрушенной лузги, что позволило получить жмых с остаточной масличностью в 12% при форпрессовании и до 6% при окончательном отжиме. Ключевые слова: обрушение, сафлор, прессование

“…Different types of seed cleaning machines are used in the technology of safflower seed preparation. The use of special machines -photo-separators [7] allows to obtain purified material of the required quality, but with low productivity and significant energy consumption. Common machines for seed preparation are pneumatic-sieve seed cleaning machines, where the separation occurs by aerodynamic properties -in pneumatic separation channels and by size -on sieves [8][9][10].…”

Separation of seed mixtures for the purpose of their purification or calibration by fractions is a mandatory technological operation in the processing of most crops. Due to its properties, the process of separation of seed mixtures of individual crops has undefined parameters or low efficiency of its flow. A similar seed material is safflower, the parameters of the purification process of which were determined in the work taking into account different methods of separation of the components of the mixture. The work involves determining the parameters of the holes of the sieves and the scheme of their installation during the separation of the seed mixture of safflower, provided the maximum quality of seeds. For this purpose, the dimensional characteristics of safflower seeds and characteristic impurities were determined, which allowed to determine the possibilities of their qualitative separation. As a result of experiments, variation curves of dimensional characteristics of safflower seed mixture components in thickness and width were established. To imitate hard-to-separate components, winter wheat and pea grains were added to safflower seeds. The efficiency of sieve separation was also determined taking into account different types of sieve openings. Studies of the process of purification of safflower seed mixture were performed both on traditional flat stamped sieves and on the proposed sieves with activators. A study on the separation of safflower seed mixtures on traditional sieves with round holes with a diameter of 5.0 mm and rectangular holes with a width of 3.0 mm has been carried out. For the first time, a sieve with five-petalled epicycloid and volume activators was used to clean the seed mixture, which, thanks to the innovative design, allows us to increase the efficiency of the separation process. For the first time, a well-grounded method of determining the coefficient, which comprehensively takes into account the parameters of holes and jumpers, can be used to optimize the parameters of seed and grain cleaning machines. The separation efficiency of the safflower seed mixture was determined both by the content of fractions and by the indicators of 1000 seed weight, germination energy and seed germination. It has been found that to increase the productivity and quality of separation, it is advisable to use sieves with sieve activators: the upper sieve with five-petalled epicycloid activators 5 mm, and the lower with elongated holes 3 mm wide as well as volume activators.

The influence of pressing conditions on the process nature and the resulting product quality was investigated in the article. This makes it possible to more deeply evaluate and understand the pressing process physics. The objects of research were safflower seeds, safflower oil and oilcake. The objects under study have various physical and technological properties that affect the pressing process, therefore, the study of these properties will help to choose the optimal modes of the pressing process in the ultrasound field, as well as to develop the design of a plant for pressing safflower seeds. To increase the oil yield, one can use the husk when adding it to the bulk of the product. The optimal moisture content range of safflower is 8-10%, which provides the minimum residual oil content and, therefore, the maximum oil yield was determined during the analysis of graphic dependencies. According to the data obtained during the experiment, graphical dependencies were built: on the speed of the screw shaft at the exit of vegetable oil; pressure in the chamber on the size of the annular space for the output of the oilcake. After analyzing the graphical dependencies, one can conclude that an increase in the rotational speed of the screw shaft leads to an increase in temperature, and this happens faster for a product with lower moisture content due to an increase in the friction coefficient of the mixture on the screw and the camera body. A numerical and graphical optimization model for predicting the optimal level of input factors and obtaining the maximum yield of safflower oil in relation to the initial mass of raw materials in% was proposed. The optimal intervals of the input parameters, such as the oscillation frequency, the oscillation amplitude, the pressure generated in the press chamber, were determined in the work..
