Abstract: Изобретение относится к биохимии и предназначено для анаэробного сбраживания органических отходов сельскохозяйственного производства с получением биогаза и органических удобрений. Биогазовая установка содержит вертикальный герметичный со съемным куполом цилиндрический  резервуар (1). В резервуаре размещены имеющий  привод (17) центральный вертикальный вал (7), барботажное перемешивающее устройство, выполненное в виде спиралевидной перфорированной трубы, и вериткальная мешалка с горизонтальными лопастями, закрепленными на вертикальном валу. Вертикальный вал выполнен полым и внутри него по высоте регулярно размещены катушки-индукторы. После заполнения вертикального герметичного цилиндрического резервуара (1) биомассой включают источник переменного напряжения (16). По обмоткам (11) начинает протекать переменный ток, который создает переменное электромагнитное поле, индуцирующее в горизонтальных лопастях (8) вихревые токи. Под действием этих токов горизонтальные лопасти (8) нагреваются и отдают свою теплоту окружающим слоям биомассы. Одновременно с этим включают привод (17), который начинает вращать центральный вертикальный вал (7). Осуществляется интенсивный и быстрый теплообмен между областями биомассы. Получаемый биогаз поступает в газгольдер, где часть его через трубопровод поступает в компрессор. Для усиления эффекта перемешивания биомассы периодически запускают барботажное перемешивающее устройство. Для этого открывают кран (20), после чего находящийся в компрессоре биогаз под давлением поступает в спиралевидную перфорированную трубу (5), выходит через отверстия (18) в биомассу, ускоряя процесс поднятия образованным метановым брожением пузырьков биогаза.

Abstract: FIELD: control and management technology. 
     SUBSTANCE: invention relates to control and measurement technology, it can be used for determining the spatial location of the pipeline axis, regardless of the features of its laying. On the pipeline, with a defined step in the projection on the axis of the pipeline, marks are installed containing spatial orientation sensors that determine the angles of rotation in the orthogonal coordinate system, azimuth and altitude position. Then, the operations of taking readings from the sensors and transmitting them to the processing point are performed, which can be implemented in one of three ways. The first one is occurred when passing an in-line device with a reader attached to it. The marks are installed on the inner surface of the pipeline, the sensors are interrogated as a result of pointing an electromagnetic field at the mark at the time of passing a reader next to it and generating an induction current in it, and the sensor readings are transmitted to the reader by means of a radio signal. The second one is occurred when performing a ground survey, it differs from the first one in that the marks are installed on the outer surface of the pipeline, and the interaction between the reader and the marks occurs outside the pipeline. The third one is occurred when connecting marks installed on the outer surface of the pipeline through communication cables with a power source, a sensor survey unit and information collection. After collecting information from the sensors, as well as determining the distance between the marks in the projection on the pipeline axis, the software is used to construct interpolating functions of the pipeline axis position in mutually perpendicular coordinate planes, as well as the rotation of the pipeline relatively to its own axis, allowing one to calculate the longitudinal and shear stresses at any point of the pipeline section caused by its spatial location.  
     EFFECT: increased accuracy of determining the spatial location of the pipeline axis.

Abstract: FIELD: food industry. 
     SUBSTANCE: group of inventions relates to food industry. Sunflower meal processing method is implemented as follows. Protein and carbohydrates are extracted from the meal by adding an aqueous solution of alkali of 5–20 % concentration to a suspension prepared from a mixture of meal and water in ratio of 1:10–20 until acidity of the suspension is set in range of 8.5–11 pH. Sodium sulphite is added to the suspension in an amount equal to 5–10 % relative to the weight of the meal; the suspension is held for 45–60 minutes at temperature of 45–60 °C. Hydrogen peroxide with concentration of not less than 37 % is added to the suspension and maintained after adding peroxide for 45–90 minutes at temperature of 45–60 °C with constant stirring. Suspension is purified from suspended particles successively, using at least one decanter centrifuge (decanter) for preliminary purification. As a result of purification, two phases are formed - liquid (extract) and solid, which is low-protein fibres (LPF). After separation on a decanter, the solid phase - wet LPF is sent for drying and granulation, and the liquid phase - the extract for final purification to a high-speed separator. Protein dissolved in the purified extract is extracted successively in two steps: at the first stage, a solution of hydrochloric or citric acid is added to the extract until the acidity value of the extract is set in range of 3.5–5 pH. Portion of the dissolved protein is deposited, then, when separating the extract, the serum formed after separating the precipitated protein is directed to an ultrafiltration (UV) membrane module, where the protein fraction not subject to acid deposition at the first stage is extracted. Precipitated protein, separated from the whey at the first stage, and the protein which has passed the ultrafiltration stage are combined and subjected to enzymatic treatment with proteolytic enzymes. Extraction of carbohydrates dissolved in the extract with formation of a saccharide solution is carried out on a reverse osmosis (RO) filtration unit, after which saccharides are subjected to concentration to obtain sugar syrup (SS). Disclosed is a version of sunflower meal processing. 
     EFFECT: group of inventions provides expansion of the range of optimum technologies for production of high-quality sunflower protein concentrate, LPF, SS from oil extraction by-products.
