In laboratory conditions, a variant of a systematic approach to the realization of experiments, involving a combination of activation and compounding of oil feedstock before primary processing, was implemented. The influence of pre-activation of raw material flows (one or both of them) in the disintegrator DA-1 and in the vortex layer apparatus on the fractional composition of compounded feedstock with the same ratio of mixed oils was studied. The possibility of priority production of the most popular fractions from various mixtures of raw materials flows has been established. Regularities of changes in the fractional composition were analyzed using a complex characteristic of oil feedstock – fluidity.

It is known that many plants represent valuable raw materials for technological processing and that there has been an increase in the use of medicinal, aromatic and spice plants as raw materials in industry. Our research was directed toward studying the rate of the distillation and yield of etheric oils from the wooded greenery of conifers (fir, spruce, pine juniper and Douglas fir) by using a new procedure. These conifers represent an important raw material basis in this area, which could be used for the industrial production of etheric oil for the pharmaceutical, cosmetic and food industry. Before distillation, the samples were treated with microwaves under laboratory conditions, and the influence of microwaves on the duration of the distillation and yield of etheric oil compared to steam distillation was analyzed. The results showed that less time was required to achieve the same yield during the distillation, if the samples were treated with microwaves, which can be a significant economic factor in the production of this etheric oil.

The nonhomogeneous physical properties of the raw material in the form of shredded logging residues, and its composition may cause a serious problem in its further use. As a result of conducted research, it was found that the elemental composition of logging residues (low nitrogen and ash contents) is suitable for raw materials dedicated to energy use. The possibility of using this raw material for the production of briquettes and the correlation between the physical properties of the final product and the parameters of the raw material and the briquetting process were also determined. The material used for tests was wood chips with moisture contents of 10%, 15%, 20%, compacted in a closed chamber at the temperatures of 22, 73 and 103 °C at unit pressures of approx. 65 MPa. The best results were obtained for the material moisture content of 10%. It was found that the temperature of the wood chips during agglomeration influences the degree of compaction and durability of the obtained briquettes. It is more advantageous to conduct compaction at a higher temperature. The research also determined the effect of the fractional composition of the briquetted mixture divided into size groups 0–1, 1–4, 4–8, and 8–16 mm, its moisture and temperature of the process on the durability of the product. On the basis of the obtained results, the most favorable fractional composition of the briquetted mixture, its moisture and temperature of the compaction process were determined.

Hyssopus officinalis L. is a promising essential oil plant of complex use containing various types of biologically active substances (BAS). The purpose of the research was twofold: study the features of accumulation of various types of BAS in H. officinalis plants grown in the foothill zone of the Crimea; assess the possibility to use them in perfumery, cosmetics, food industry, pharmacy and medicine. The research was conducted in 2017–2019 in the FSBSI “Research Institute of Agriculture of Crimea”. The raw materials of H. officinalis (population with blue flowers) grown without irrigation served as the research material. Qualitative and quantitative characteristics of raw materials and different types of BAS were determined according to generally accepted methods. Structural analysis of H. officinalis showed that the aboveground part of plants during the growing season had the following fractional composition: leaves (21.4–70.6 %), stems (18.8–30.9 %), inflorescences (22.0−59.1 %). The ratio of fractions by phases of vegetation varied, namely: in the phase of regrowth, leaves prevailed – 70.6 % but, at the end of the flowering, their content decreased to 21.4 %; the content of inflorescences reached its maximum in the phases of mass flowering and end of flowering 53.3–59.1 %. The main oil-synthesizing organs of H. officinalis were leaves and inflorescences. The highest yield amount of H. officinalis essential oil was obtained from inflorescences (1.94 %), which in the fractional composition of the raw material amounted to 53.3 %. The maximum amount of essential oil of specific quality accumulated in plants during the phase of mass flowering (1.26 % in terms of absolutely dry weight). The dominant components of essential oil are ketones: isopinocamphone and pinocamphone (75.9–78.6 %). A high level of phenolic compounds was determined in the phases of regrowth and flowering; extractive substances – in the budding phase; tannins – in the phase of mass flowering. During the storage of air-dry raw materials for two years, insignificant losses of essential oil occur (up to 20.2 %); its component composition changes (hydrocarbons amount decreased by 2.5–22.7 %; ketones – increased by 3.4–16.2 %). The content of other types of BAS during storage of raw materials increased by 10–30 %. Therefore, it is advisable to store air-dry raw materials of Hyssopus officinalis for two years or longer.

Due to the rapid growth in the production and consumption of shisha tobacco in the Russian Federation, it has become necessary to improve the technology using optimal ingredient composition in order to create a high-quality and safe tobacco product. The aim of the research is to improve the technology of manufacturing shisha tobacco based on the optimization of its ingredient composition; to study the influence of the fractional composition of raw tobacco on its quality indicators. Fractional composition of raw tobacco in the production of shisha tobacco, as well as for other tobacco products, is important and affects its quality characteristics. Virginia and Burley tobaccos of the American type are the most demanded ones in the manufacture of shisha tobacco [1]. Sometimes oriental-type tobaccos are used in the bag, which are distinguished by high taste and aromatic qualities. Due to the fact that recently there has been an increase in the demand for Doha Arabian tobacco raw material (this tobacco is known as a high-quality product with a high strength and a pleasant, full and harmonious taste), the idea has arisen to manufacture prototypes of shisha mixtures in which Doha tobacco is used [2]. The article presents the research results: to determine the optimal ingredient composition of hookah tobacco; to study the optimal fractional composition of raw tobacco of various types. As a result of the research the chemical composition of raw tobacco of various types has been analyzed, the tasting and organoleptic evaluation of the prototypes carried out and the tobacco raw material most suitable for the production of shisha tobacco determined; the nicotine content in the condensate of prototypes of shisha mixtures with different fractions of raw tobacco determined; the optimal fractional composition for various types of tobacco raw materials, necessary for the production of a quality product determined.

Industrial hemp as a source of fiber is a valuable industrial raw material. In modern conditions, the lines of its primary processing should produce the same type of fiber with different characteristics, depending on the requirements for the properties of the finished fiber. The purpose of the work is to substantiate the scheme for processing industrial hemp based on the characteristics of hemp. Five primary processing lines were compared, including domestic flax equipment (M-110L2 grinding machine, DLV-2 disintegrators, and TG-135L shaker machines with a lower comb field). As raw materials the industrial hemp from Penza region, harvested in the spring, was used. The mass of one handful is 100 g, the loading density is 0.5 kg/m, the twist is three times. Raw materials were loaded into each machine manually. After primary processing by instrumental methods, hemp grade and characteristics were determined according to GOST 9993-2014. The scheme of the line for primary processing of industrial hemp in the form of tangled mass of stems of various lengths, which allows the production of the same type of hemp with different values of technological characteristics, has been developed. For the production of the same type of hemp with an average mass length of fiber 142 ... 144 mm, a mass fraction of bonfire of 1.6 ... 2.2%, a weighted average linear density of 11 ... 12 tex, the line should include a pulping machine, a disintegrator, two shaking machines; with characteristics respectively 235 mm, 7 ... 8% and 12 ... 13 tex - a disintegrator and two shaking machines; 219 mm and 15 ... 16%, 18 ... 19 tex - pulley and two shaking machines. Using the studied set of equipment provides a reduction in capital costs, in comparison with the lines of other manufacturers, by 3 ... 4 times, energy costs - up to 40%

Introduction. The objective of the research is to study the effect of the complex activation of the alumina raw material on the rheological properties of the ceramic mass. In addition, the authors investigate solutions for the application of optimal coagulation structures based on loams and ash together with plastic certificates.Materials and methods. The authors used the local forest like reserves of clay loams at the BashKarasu, ash fields of the Bishkek Central Heating Centre (BTEC) and plasticizer (sodium naphthenate obtained from alkaline chemical production wastes) as fibrous materials. Moreover, the authors defined technological properties of raw materials within standard laboratory methodology in accordance with current GOSTs.Results. The researchers tested plastic durability on variously prepared masses for the choice of optimal structures. The paper demonstrated the plastic durability of complexly activated compounds comparing with non-activated and mechanically activated compounds. The sensitivity coefficient increased the amount of clay loams by mechanically and complexly activated, which predetermined the possibility of intensifying the process of drying samples based on complexly activated masses.Discussion and conclusions. However, mechanical activation of clay material reduces the period of relaxation and increases the elasticity coefficient of ceramic masses by 1.8–3.4 times, meanwhile decreases elasticity, viscosity and the conventional power during molding, which generally worsens the molding properties of the masses. Сomplex activation of ash-clay material decreases the period of relaxation and provides an increase in elasticity, plasticity of ceramic masses by 46–47%, reduction in viscosity by 1.5–2 times, conventional power on molding by 37–122% in comparison with MA clay loams. Ceramic masses based on spacecraft alumina raw materials belong to the SMT with improved rheological properties; products based on them pass through the mouthpiece for 5–7 seconds.

Organic materials that are generally used as raw material for organic fertilizer granules (POG) is a natural organic material that has been degrade, smooth and dry. One of the main raw materials are always used with a very high percentage of usage, is manure. Manure potential in Indonesia is very high, amounting to 113.6 million tons per year, or 64.7 million tons per year to the island of Java. From this amount, it will be generated numbers POG production potential of 17.5 million tons per year (total Indonesia) or 9.9 million tons per year for the island of Java. While the realistic POG production predictions figures made from raw manure is 2.5 million tons annually, a figure that has been unable to meet the number requirement of POG greater than 4 million tons per year. Therefore, in producing POG, it should be to maximize the using of the potential of other organic materials so that the use of manure can be saved. With the use of a small amount of manure (maximum 30% for cow manure), it would be useful also to avoid the production of POG with high Fe content.keywods: organic material, manure, granule organic fertilizer
