Studie technologického vybavení pro zpracování matolin ve vybraném vinařském provozu
Musil, Miroslav
The bachelor thesis describes the characteristics of wine grapes and grapes. The process of processing matolin and their possible use was described. As a basic issue was solved the technological equipment for processing of matolin, focusing on separation of grapevine seeds and subsequent pressing of oil. For each technological operation, possible variants of machines were selected. The present state of grape processing is presented both in the Czech Republic and in selected wine-growing operations. The net yield of seeds for subsequent pressing of grape oil ranges from 5 to 7% of the weight of the processed grapes. Pure grape-oil molding, ie. the amount of oil after filtration varies between about 5-9%, depending on the grape variety. of one kilogram of wine kernels can be pressed about 50-90 grams of grape oil. The cost of processing one kilogram of grape seed and pressing grape seed oil from wine grains is 26,40 CZK / kg. At the selling price of crude oil CZK 300 it is more than ten times the profit. The created design of the technological equipment for the processing of matolin is complemented by the capacities of individual machines. At the end, the cost of grape oil production and the cost of processing grapevine seeds for the medium and small vintages are calculated. The market price of the treated oil was determined on the basis of a market survey, see Tab. 5, is about 1300 CZK / kg. It is necessary to take into account that the price already reflects the final adjustments like, directing, producer's profit, dealer's sales margin, marketing costs and more. The selected winemaking enterprise has a gross profit of CZK 385,000. The investment costs for the assembly line for the processing of matolin are CZK 850,000. The return on investment is 2.2 years. It was recommended to separate the grapevine seeds and press the grape oil. For a small winery, the gross profit is CZK 139,000. The investment costs for the assembly of the processing line for matolin (about 1/3 times less than for the medium wine-growing enterprise) are CZK 570,000. The return on investment is 4.1 years. Rather, it was not recommended to separate the grapevine and grape seed.

Benda, Vojtěch
This diploma thesis deals with the design of sawmill operation at Pila Benda s.r.o. in Velký Pěčín. The thesis deals with the current state of operation in Firm, its production capacities, and the location for new Firm. The main part deals with three alternatives of sawmill design, three alternatives of logs storage and three alternatives of pallet production. All nine alternatives are supported by a drawing and all machines used in production are listed. The most suitable solution is recommended in the last part.

Možnosti rekonstrukce pily ve Zbraslavicích
Seifert, Jaroslav
The thesis describes the reconstruction and modernization of the associated sawmill in the company Joinery Seifert, village located in Kutná Hora region. Joinery Seifert is company with 21 years tradition. They use sawmill for own needs of workshop, which currently handles about 150 m3 saw logs per year. Owner of the company Mr. Seifert wants to became independent sawmill and expand the volume of processed saw logs on 2 000 m3 per year to mainly construction lumber in one -- shift production. In first part of the project is analyse of present state production, volume processed saw logs and technological equipment. In second part of the thesis are suggestions of individual variations of sawmills with technical draw documentation and extract machine -- technological equipment. The third part provides economic analysis individual variation and their comparison. In last part is the suggestion of optimal variant with economic analysis. The result of the thesis is a study that will serve as a basis for owner to the possible modernization of sawmill.

Rekonstrukce pilařského provozu a výroby palet a obalů firmy Karel Vlček, Branka u Opavy
Havel, Lukáš
The thesis deals of the reconstructions of sawmill operations and productions of pallets and packing at Branka u Opavy. The sawmill procceses about 20 000 cbm/year. All manufactured lumber is used for follow-up productions of pallets and containers. The thesis is carried out according to the requirement of the company. The main goal is a new sawmill while maintaining the existing one. In the first part of the thesis deals with the analysis of the current state of the company. Next, there are three variants of solution. These proposals will be awared variants and economic evaluation. Acording to the technological advantages and economic evaluations there will be selected the optimal alternative way, which will be recommended for further process.
