“…Regardless of the method of sampling the next important step is the assessment of a condition of the mixture. In this area numerous studies are still conducted, and new tools and methods are developed and implemented by, among others, the author of the present study (Eisenberg, 1992;Realpe and Velazqez, 2003;Djuragic et al, 2009;Siiriä and Yliruusi, 2009;Obregón et al, 2010;Matuszek and Szwedziak, 2013;Matuszek, 2015;Realpe et al, 2015).…”

This paper presents a consecutive stage of the research aimed at developing a methodology for the application of fluorescence to evaluate the homogeneity of granular and loose mixtures. At this stage it was examined which of the selected components of feeds are suitable to be use in the proposed method. The experiments were conducted with the use of three components: wheat, kardi, barley. Each of the materials was wet dressed with a solution of a fluorescent material. In the study the substances having the characteristics of fluorescence under UV light such as: tinopal, rhodamine B, uranine, eosin, were applied. The assessment of the homogeneity of a ternary granular system was performed based on the share of a tracer, which was a component coated with a fluorescence substance. In the method a computer image analysis was used. Based on the conducted observations and statistical calculations it was demonstrated that only kardi meets the requirements necessary for the application in the tested method. The remaining components: wheat and barley were excluded. Moreover, types and concentration of fluorescent substances were determined and the methodology was clarified. , 2017, 18(4), p.851-863 DOI: 10.5513/JCEA01/18.4.1966 851 Journal of Central European Agriculture, 2017, 18(4), p.851-863 DOI: 10.5513/JCEA01/18.4.1966 851 Journal of Central European Agriculture, 2017, 18(4), p.851-863 DOI: 10.5513/JCEA01/18.4.1966 851 Journal of Central European Agriculture, 2017, 18(4), p.851-863 DOI: 10.5513/JCEA01/18.4.1966 danego składnika pokrytego substancją fluorescencyjną. W metodzie wykorzystano komputerową analizę obrazu. Na podstawie dokonanych obserwacji oraz obliczeń statystycznych, wykazano, iż tylko kardi spełnia wymagania niezbędne do zastosowania w testowanej metodzie. Pozostałe składniki: pszenica i jęczmień zostały odrzucone. Dodatkowo określono rodzaje i stężenie substancji fluorescencyjnych oraz doprecyzowano metodykę.of Central European Agriculture, 2017, 18(4), p.851-863 DOI: 10.5513/JCEA01/18.4.1966 851 Journal of Central European Agriculture, 2017, 18(4), p.851-863 DOI: 10.5513/JCEA01/18.4.1966 851 Journal of Central European Agriculture

The paper presents a change in physical properties of loose, dust fodder additives (aluminosilicate) after mixing them with oil or glycerine. Additives where mixed in a blade mixer with the same mixing time for all samples, which was 1 minute. Tests with oil or glycerine were carried out in the following amounts: 5%, 10%. For mixtures of additives with oil or glycerine a selected group of physical properties was determined. Method of determination of physical properties was the same for all samples i.e. the same additives − without oil and glycerine as well as mixtures with their participation. Obtained research results and their analysis unanimously indicate that adding any amount of oil or glycerine for additives improves selected physical properties of mixtures. Key words: mixing, physical properties, fodder additives, fodder IntroductionMixing is an essential stage in the industrial production of fodder mixtures. Blade mixers or band mixers for which producer states theoretical time of indispensable mixing of raw materials are the most often used. However, the mixing time depends on physical properties of mixed raw material and the time given by a producer of a mixer should be corrected after the tests on mixing uniformity (Laurent et al., 2002). Homogeneity of a mixture is checked, inter alia, with microindexes namely with iron filings (Zawiślak et al., 2012, Kró-lczyk et al., 2005, 2008. Standard ADAE (no.S303) describes the procedure of operation (Siiriä and Yliruusi, 2009, Zawiślak et al., 2011).Fodder additive means various substances used in feeding animals as supplementation of basic nutrients, vitamins and mineral compounds. Fodder additives favourably influence generally understood health of animals and improve functioning of their organisms leading to faster and efficient increase of muscle and fat tissue. Their presence in the feed dose increases productivity, improves the fodder quality (image, taste, smell, consistency, shell life) (Grochowicz and Walczyński, 2004, Heidenreich and Strauch, 2000, Putier 2001.The following are the most often used fodder additives: -probiotics, -fodder enzymes, -aromatic and taste additives, -dyes, -preservatives, -detoxification -substances including an active group (e.g. aluminosilicate) which are not digested but bind toxic metabolites and mitotoxines secreted by undesired microorganisms which, as a result, go through a digestive tract in the unchanged form and are egested with feces without any detrimental influence on the animal body -antioxidants, -other different food products (Matuszek 2012, Zawiślak et al., 2011Molognoni et al., 2017). The objective and scope of researchThe objective of the presented research is to improve physical properties of fodder additives with regard to the possibilities of a precise dosing to fodder mixtures and reduce their powder character. Methodology of researchTwo different aluminosilicates marked as follows were used in the tests: "Additive 1" and "Additive 2" as labels used in all stages of experiment. Aluminosilicates inclu...

“…Agitators of this type are called double volute agitators (they may also be referred to split volute agitators). In some applications the double volute minimizes radial forces imparted to the shaft and bearings due to imbalances in the pressure around the impeller [11]. Centrifugal agitators contain rotating impellers within stationary agitator casings.…”

This research is to design and implement a new kind of agitators called d ifferential agitator. The DifferentialAgitator is an electro-mechanic set consists of two shafts. The first shaft is the bearing axis wh ile the second shaft is the axis of the quartet upper bearing impellers group and the triple lo wer group wh ich are called as agitating group. The agitating group is located inside a cy lindrical container equipped especially to contain square directors for the liqu id entrance and square directors called fixing group for the liquid exit. The fixing group is installed containing the agitating group inside any tank whether fro m upper or lower position. The agitating process occurs through the agitating group bearing causing a lower pressure over the upper group leading to withdrawing the liquid fro m the square directors of the liquid entering and consequently the liquid moves to the denser place under the quartet upper group. Then, the liquid moves to the so high pressure area under the agitating group causing the liquid to exit fro m the square directors in the bottom of the container. For improving efficiency, parametric study and shape optimization has been carried out. A numerical analysis, manufacturing and laboratory experiments were conducted to design and imple ment the differential agitator. Knowing the material prosperities and the loading conditions, the FEM using ANSYS11 was used to get the optimu m design of the geometrical parameters of the differential agitator elements while the experimental test was performed to validate the advantages of the differential agitators to give a h igh agitation performance of lime in the water as an example. In addit ion, the experimental work has been done to e xpress the internal container shape in the agitation efficiency. The study ended up with conclusions to maximize ag itator perfo rmance and optimize the geometrical parameters to be used for manufacturing the differential agitator.
