Finanční zhodnocení možností výroby pomerančového oleje ve zvoleném regionu
Smíšková, Michaela
This thesis deals with the possibility of the processing of orange peels, that are available for juice producers after the production process and currently are determined to landfill. Proposed practical project explores the need for further use of orange oil, which can bring economic profit to local farmers, help to create new job opportunity and contribute to the overall development of the region. The issue of agrarian sector is described in the theoretical part. By verifying the feasibility of the project deals with both the analytical part of the empirical section, which indicates the initial state, problems and circumstances of the region Eastern Cape and practical part in which compression method is selected as the most effective for this type of production and expected investments are evaluated in the context of financial analysis. The work confirms the possibility of using this type of waste as a natural mechanism of value-added manufacturer of juice and understands the production of an economic, environmental and social benefits for the monitored region.

Hodnocení lisovacích účinků ve vinařských provozech
Kosík, Jiří
This thesis describes methods of work and structural variants of wine presses used in modern wineries in detail. It summarizes strengths and weaknesses of technological solutions. The practical part of the thesis deals with the evaluation of two presses, each of which is based on a different principle. The effects of pressing were observed during the processing of three grape varieties -- Sauvignon, Chardonnay and Zweigeltrebe -- in 2011, 2012 and 2013. The amount of pressure, processing, most gain and productivity were assessed. The cost of processing one hectolitre of the product was fixed for both systems.

Manufacturing of metal yoke of electrical socket by compound tool
Svozilová, Lucie ; Řiháček, Jan (referee) ; Peterková, Eva (advisor)
The project elaborated design of technology production of the metal yoke of electrical socket made of steel DX51D + Z200 by compound progressive tool. Stock material for series of 200 000 pieces is a strip of coil. Manufacturing is realised in five steps consist of cutting, bending and flanging. For flanging was constructed a special mechanism for whose is necessary to use hydraulic counterholder, which is sold as a special peripheral equipment of manufacturing machine. The machine choice was adapted to this criterium. The servopress DSF-N1-800A was chosen as a manufacturing machine, which is made by AIDA company. The press can produce force of 800 kN and make work of 4000 J. Selling price of a one yoke is 24,5 Kč when the profit is one hundred percent. The break-even point comes with 58 140 made piece.

Production of joint folded out the rule
Šoukal, Hynek ; Podaný, Kamil (referee) ; Žák, Ladislav (advisor)
Project developed within the bachelor study presents a proposal production technology of joint folded out the rule from construction steel 12 060. Thick is 0,5 mm and the production ran is specify at 30 000 units a year. In accordance with literature studies and by calculations have been designed a combined roll forming tool, which consists of a rack with two pillars. This tool will be fix in on eccentric press LEN 10C by SMERAL, Trnava, with nominal press force 100 kN. Trimming punches, holding punch and bending puch are made of tool steel, grade 19 436.3. Lower functional part of the tool ass well.

Pressure losses in heating systems
Švanda, Martin ; Horká, Lucie (referee) ; Počinková, Marcela (advisor)
This diploma thesis deals with pressure losses in heating systems. The diploma thesis is divided into three sections. The first part is theoretical and deals with the occurrence of pressure losses. It discusses the properties of the fluid that affect pressure losses. It also deals with hydrodynamic phenomena, flow distribution, pressure loss distribution and its calculations. The aim of the second part, which is practical, was to create a heating project for a selected object. The object is a two-floor kindergarten building located in Velké Němčice. For this project, two heating variants were created. For the first variant, radiators and heating benches were designed and for the second variant, underfloor heating was installed in the building. The goal was to use a source which will gain heat mainly from renewable sources, so the air / water heat pump was chosen as the source of heat production. The project ends with a technical report. The third part of the thesis is dedicated to an experiment which purpose was to find out how the pressure losses of the connecting pieces are reacting to the change with the change of the heating water conditions (flow, temperature). Alongside, two pipes were created which differed in the type of connecting pieces so it allowed to compare how their pressure losses differ. Both pipes were connected by radial pressing, but the fittings differed in the quality of the brass, and therefore in the construction. Also, part of the experimental section of the diploma thesis is a description of the course of radial pressing of fittings from the Herz company.
