Therefore, the main goal of the studies is to determine the mass loss of 7 and 8 mm thick samples made of Armox 600, Ramor 500 and S355 steel. The study was carried...
The main purpose of the paper is presentation of the possibilities of non-destructive methods for determination of structural discontinuity of the selected parts of motor vehicle chassis systems, responsible for safety of their operating. In the paper are shown non-destructive methods in aspect of their application to condition assessment of parts of machines and vehicles, and examples of application...
This paper presents the results of the evaluation of feed quality conducted on the basis of the content of a tracer coated with a fluorescent substance. The study used the example of compound feed mixture for laying hens. Feed ingredients: maize and kardi primed wet using fluorescent solutions. The substances, such as Tinopal, Uranine and Rhodamine B were excited to shining by ultraviolet radiation...
The conducted study aimed at the determination of the optimum share of the blue and yellow lupin in mixtures with the naked barley for the seed yielding on less productive land. An analysis of the component biometric characters and their yielding level constituted the basis for the determination of the optimum mixture for cultivation in specific soil conditions. The study was conducted on dusty soil...
This paper features project assumptions, the description of the patented in ITP research station for the innovative cooling and heating system in pens for farrowing sows and piglets and the research methodology. Field tests aim at specifying energy efficiency and economy of the tested system and the impact of the heat recovery installation in the pen on animals’ behaviour, health, body weight gain...
In the paper there are presented economic and material expenditures incurred during ensiling the sugar beet pulp in various forms of their storage: cylindrical bales wrapped with foil - ZPO, foil bag - ZWF and passage silo - ZSP. A computational algorithm was developed allowing determination of criterion indicators for which: fuel consumption, labor input and costs per unit weight of ensiled pulp...
The study investigated the physical properties of onion for purpose of developing a mechanical peel assembly. In addition, tests of cutting force and compressive stresses resulting in onion damage were performed. The results of study constitute the basis for developing a concept of main mechanical peeling assembly, which is responsible for incision of top layer onion and removal of a root and pinch.
This paper describes strength evaluation for D4CS4 FA20.25 bracket, mounted in tractors of the URSUS Company. The analysis was based on stress modelling, supported by the finite element method (FEM). It was assumed in the model that the studied element was made of ductile cast iron and subject to three forces at three support points. Stress distribution simulations were run for various boundary conditions...
The aim of the paper was to show how cooling of silicone photovoltaic cells influences the amount of electrical energy they produce. The research was conducted both in the laboratory and under real outdoor conditions. Current-voltage characteristics for two different thermal states of PV cells were outlined. Obtained power values for a PV cell working under the influence of refrigerant and without...
The aim of the research was to analyse the process of onion waste pelleting in terms of its use as a fodder additive. The paper assesses the influence of the moisture content of shredded onion waste on the energy consumption of the pelleting system and the density and kinetic durability of the obtained pellets. The tests of the pelleting process were carried out on an SS-4 stand, whose main component...
The main goal of the research was to design and build a prototype of device used for pneumatic transport, which will increase the difference of pressure in the pipeline and will increase velocity of the airflow during the transport of materials over different distances. During design process of the device using graphics software assumes that the system of separation of grain and air should be eliminated...
Granulation is a process of agglomeration of small particles of shredded materials into larger units and is carried out in the presence of liquid. As far as the energy used in agglomeration is concerned, the process can be divided into pressure pelletizing: pressing, tableting, briquetting, and extrusion, and low pressure granulation, commonly known as non-pressure granulation, which primarily consists...
We assessed the impact of working parameters of Z056 Bizon Super on the quantity and quality losses of seeds during soya harvesting. We investigated soya of Merlin variety cultivated in Leszczany (51°021 N; 23°602 E). We found out that the lowest total quantity losses of soya (11.6%) occurred at the working speed of a harvester of 4 km·h-1, slightly higher (11.78%) at the speed of 2.5 km·h-1, and...
In the paper results of experiments on hydrodynamic assessment of gas flow through backbone (skeletal) porous materials with an anisotropic structure are presented. The research was carried out on materials of different petrographic characteristics and origin of process (char). The study was conducted for a variety of hydrodynamic conditions with the use of air. As the basis for the hydrodynamics...
The paper presents results of research on quality characteristics of briquettes made from selected raw materials of plant origin. The following raw materials were used: corn straw, oat straw, and chamomile waste. Cereal straw was crushed using H 111/1 shredder equipped with a screen with a diameter of 20 mm. For the production of briquettes, a hydraulic piston briquetting machine of JUNIOR type from...
The aim of the study was to determine the potential and possibilities of use of computer analysis and image processing in the agri-food industry in Poland, with particular emphasis on the agricultural sector. The paper presents the results of tests of selected physical parameters of agricultural and horticultural fertilizers present on the Polish retail market. The study was performed with the use...
The paper presents the results of laboratory tests on the shape and dimensions of cereal seeds and other crop plants necessary for modeling the sowing and separation of these seeds. Individual grains are not usually identical, so their linear dimensions are not uniform in different directions. The ability to determine the shape and dimensions of grains is extremely important from the point of view...
