The paper is concerned with some aspects of processing raw potato peelings. It presents the dynamics of potato production in the world and in Ukraine, and analyses the figures on yields of this crop. Methods of processing potatoes at Ukrainian enterprises have been considered. It has been found that the bulk of the waste (15–60%) is formed during peeling raw potatoes. Methods of utilisation of potato peelings have been analysed. Problems of using fresh potato peel in the diet of farm livestock have been analysed. The technological operations of potato waste processing have been considered, and it has been substantiated how practical the method of extrusion is. The advantages of manufacturing an extruded feed additive with the use of potato peel have been shown. The physical properties, chemical composition, and term of storage of fresh potato peel have been determined. It has been found that fresh potato peel is poorly storable and hardly flowable, so it must be processed within 48 hours. To produce an extruded feed additive including crushed wheat grain and fresh potato peel in the ratio 9:1, a step-by-step scheme has been developed. The physical properties, the content of individual nutrients and minerals, and the shelf life of the extruded additive have been determined. It has been established that manufacturing the feed additive by the method suggested allows increasing the product’s nutritional value, prolonging its shelf life, improving its sanitary quality, technological properties, and conditions of feeding potato peel to livestock. It has been found that when the amount of potato peel introduced is 10% and that of crushed wheat grain is 90%, the optimal moisture content is 16.5%. Besides, this ratio results in the minimum energy consumption and in a coefficient of expansion high enough. During extrusion, the physical properties change: the moisture content, angle of repose, and bulk density decrease, while the flowability increases, which makes the feed additive suitable for use in the feed products technology. Besides, extrusion of the feed additive is accompanied by reduction in crude protein, crude fibre, and crude fat. It has been established that the shelf life of the additive is 4 months

The main task of the compound feed industry is development and introduction of high-performance equipment and technologies, expansion of the resource base and the range of finished products. Along with this, in the canning industry, a lot of by-products are formed. By their chemical composition, they are as good as the main products. However, by-products of the canning industry are characterized by a high moisture content. They deteriorate very quickly and require immediate disposal. That is why, the purpose of the paper was to study the effect of heat treatment on the physicochemical properties and on the quantitative and qualitative composition of the microflora of the feed additive made with the use of carrot pomace. The physical properties, chemical composition, sanitary quality, and permissible shelf life of carrot pomace have been determined. The optimum quantitative and qualitative composition of the feed additive have been reasoned and researched. It has been established that the process of extrusion improves the physical properties and increases the digestibility of nutrients. It also improves the sanitary condition and extends the shelf life of the additive. As a result of extrusion of the feed additive, the moisture content decreased by 32.2%, the angle of repose increased by 11.8%, the flowability decreased by 33.3%, the damaged starch content decreased by 33.2%, and the amount of water-soluble carbohydrates became 5 times as big. Besides, under the influence of high temperature and pressure, the total number of bacteria decreased by 89%, and that of mould fungi by 83%. During storage of the feed additive for 6 months, the QMAFAnM decreased by 32.5%. The resulting feed additive will solve the problem utilizing canning industry by-products, expand the raw material base and reduce feed consumption.

In the article the advantages of using grain legumes as protein plant concentrates are analysed, and a comparative analysis of the chemical composition of the pea and the soybean meal is carried out. Besides, the official parameters for different protein products for pig feeding are presented. To determine whether it is possible to introduce protein plant concentrates into compound feed, it is necessary to know their physical properties. So, the physical properties of the protein plant concentrates have been investigated for the following parameters: moisture content, bulk density, angle of repose, and flowability. Methods of introducing protein plant concentrates into compound feeds have been developed and presented. Taking into account the physical properties and norms of introducing protein plant concentrates for farm animals and poultry, a scheme has been developed for a technological line preparing a portion of grain, powdery, mineral raw materials and meals. One of the methods of introducing protein plant concentrates into compound feeds is extrusion. That is why, a technological scheme of an extrusion line for grain legumes has been developed. The technological scheme provides for the extrusion of a soybeans and peas mixture in the ratio 1:1. Also, the physical properties of the extruded feed additive have been studied. With the software package “Korm Optima Expert,” recipes for feeding piglets aged 43–60 days have been calculated (with protein plant concentrates used in the recipes), and some feeds of animal origin have been replaced with extruded feed additives. According to the calculated recipes, an experimental batch of mixed feeds with the use of protein plant concentrates has been manufactured, and its physical properties have been determined.

The drying process of corn noodles was an effort to increase the shelf life and it was a form of noodles diversification. The objective of this research was to study and analyze the effect of guar gum addition on the physical quality of the extruded dry corn noodle made from a mixture of wet and dry corn flour. Manufacturing dry corn noodles was conducted using wet corn noodles from a mixture of wet and dry corn flour, which was then dried in a tray dryer at a temperature of 60-70 °C for 1 - 1.5 hours. The treatments used were a combination of alum levels of 0.01%; moisture content of 80% (dry base); and guar gum concentration of 0%, 1%, and 2%. Physical properties of dry corn noodles included rehydration time, hardness, adhesiveness, suppleness, elongation, and cooking loss. The results showed that the optimum rehydration time for dry corn noodles was about 9 minutes. The addition of guar gum to the physical qualities of dry corn noodles tended not to be significant statistically, but as a score, an increase in guar gum levels tended to increase the elongation of dry corn noodles. While, increasing levels of guar gum tended to reduce the stickiness and cooking loss levels of them.

The properties of particleboards and the course of their manufacturing process depend on the characteristics of wood particles, their degree of fineness, geometry, and moisture content. This research work aims to investigate the physical properties of wood particles used in the particleboard production in dependence on their moisture content. Two types of particles currently used in the production of three-layer particleboards, i.e., microparticles (MP) for the outer layers of particleboards and particles for the core layers (PCL), were used in the study. The particles with a moisture content of 0.55%, 3.5%, 7%, 10%, 15%, and 20% were tested for their poured bulk density (ρp), tapped bulk density (ρt), compression ratio (k), angle of repose (αR), and slippery angle of repose (αs). It was found that irrespective of the fineness of the particles, an increase in their moisture content caused an increase in the angle of repose and slippery angle of repose and an increase in poured and tapped bulk density, while for PCL, the biggest changes in bulk density occurred in the range up to 15% of moisture content, and for MP in the range above 7% of moisture content, respectively. An increase in the moisture content of PCL in the range studied results in a significant increase in the compression ratio from 47.1% to 66.7%. The compression ratio of MP increases only up to 15% of their moisture content—a change of value from 47.1% to 58.7%.

Abstract.The knowledge of physical and thermal properties in cereals, grains, and oilseeds establishes an essential engineering tool for the design of equipment, storage structures, and processes. The physical properties and thermal properties for Chia, Kañiwa, Farro, and Triticale grains were investigated at three levels of moisture content: 10%, 15%, and 20% (d.b.). Physical properties included 1000-seed weight, dimensions, mean diameters, surface area, volume, sphericity, and aspect ratio. Results indicated 1000-seed weight increased linearly with moisture content from 2.0 to 3.5 g for chia, 2.5 to 4.0 g for kañiwa, 42.7 to 48.3 g for farro, and 51.0 to 53.7 g for triticale. The porosity for farro and triticale increased from 38.71% to 44.1%, 40.37% to 44.65%, respectively, as moisture increased. Angle of repose increased as moisture content increased, as did values of L, a*, and b* for all grains. Thermal properties of kañiwa, farro, and triticale showed high correlation to moisture content. A negative relationship was observed for the specific heat capacity and thermal conductivity, while the thermal diffusivity had a positive linear increase trend with moisture content. This study showed that physical and thermal properties varied from grain to grain as a function of moisture content, and these data will be useful for future application development.

Knowledge of agricultural seeds’ physical properties has significant importance for machinery and processing equipment design. Physical properties of flixweed (Descur ainia sophia L.) seeds were determined as a function of moisture content. Several properties were studied in the moisture range from 5.28 to 17.53% dry basis. Also, probability distribution of seeds’ principal dimensions were modeled by Gamma, Generalized Extreme Value, Lognormal, and Weibull functions. With increasing moisture content from 5.28 to 17.53%, properties including; length, width, thickness, geometric and arithmetic mean diameter, sphericity, specific surface area, volume, and projected area showed no specific trend. In contrast, the surface area increased from 6×10-7 to 1×10-6 m2. The bulk and particle density decreased from 696.61 to 542.51 kg·m-3, and 1217.50 to 1189.02 kg·m-3, respectively. The porosity increased from 42.78 to 54.37%. The maximum external static angle of friction belonged to wood at all moisture content levels, followed by the iron and galvanized surfaces. At all moisture levels, the emptying angle of repose was more than the filling one.

Abstract Some physical properties of the naked oat seeds were determined as a function of moisture content ranging from 9.56 to 18.07% (wet basis, w.b.). Seed length, width, thickness, and geometric mean diameter were increased from 7.89 to 8.81 mm, 2.32 to 3.09 mm, 1.85 to 2.77 mm, and 3.24 to 4.22 mm, respectively, with the increase of moisture content. The bulk and true densities of the seed samples were decreased from 682.1 to 533.1 kg/m3 and from 1,280.6 to 1,162.8 kg/m3, respectively. The average static friction coefficients of the seeds on the surfaces of plywood, stainless steel, and polypropylene knitted bags were increased from 0.403 to 0.674, from 0.371 to 0.496, and from 0.562 to 0.765, respectively, when the moisture content of these samples were increased from 9.56 to 18.07% (w.b.). The static angle of repose varied from 24.38° to 39.17° in the moisture content range.
