This bachelor's thesis deals with the design of a mechanical fruit press, focusing on both the visual and functional design, and the subsequent manufacture of its main component – the portal. The theoretical part includes mapping the historical development of pressing, construction solutions currently used in press production, and hygienic requirements for food-contact materials. The practical part is based on the conceptual and mechanical design of the press with a pressing capacity of 55 liters, emphasizing the aesthetic aspect of the machine. The thesis includes a computational analysis and a deformation check of the motion mechanism, as well as a numerical FEM analysis of the portal made out of EN-GJS-400 ductile iron. The conclusion of the thesis describes the actual technological manufacturing process of the portal by casting into split sand mold.
