Abstract (Croatian)
Tema ovog rada je koncipiranje i konstrukcijska razrada stroja za hladno prešanje ulja koji osim uobičajenog pogona elektromotorom mora imati mogućnosti i ručnog pogona u slučaju nestanka (ili izostanka) električne energije. U uvodnom dijelu rada ukratko je opisana razlika između hladno i vruće prešanih ulja, te je dan prikaz nekih hladno prešanih ulja dobivenih iz sjemenki bez koštice. Također, prikazana je podjela strojeva za dobivanje ulja na dvije glavne skupine, te je opisan princip rada i njihovi osnovni dijelovi. Nadalje, napravljena je analiza tržišta i prikaz postojećih rješenja sličnih strojeva za hladno prešanje ulja. Funkcijskom dekompozicijom dan je prikaz osnovnih funkcija stroja, dok su morfološkom matricom prikazane neke od mogućnosti izvođenja tih funkcija. Na temelju toga osmišljena su četiri koncepta od kojih je samo jedan, nakon vrednovanja, išao u detaljnu konstrukcijsku razradu. Na kraju su nakon proračuna odabrane potrebne dimenzije osnovnih dijelova stroja, kao i neke standardne komponente, kako bi se ostvarili traženi parametri. Nakon svega, izrađen je računalni model i potrebna tehnička dokumentacija.
Abstract
The subject of this paper is conceiving and design development of a cold press oil machine that is powered by conventional electromotor, but has the ability to be manually driven in the event of a power loss or a shortage. In the introductory chapter, there is a brief description of differences between cold and hot pressed oils, and a review of some cold pressed oils obtained from pitiless seeds. Also, there is a classification of oil-manufacturing machines into two major groups, and a description of their operating principle and some basic parts. Furthermore, a market analysis has been conducted alongside a review of some existing machine solutions for cold oil pressing. Few of the basic function of the machine are given through the functional decomposition, while some of the possible designs for those functions are presented in the morphological matrix. Based on those data, four concept machines were taken into consideration. After evaluation, only one of those staged through the final design elaboration. To achieve the required parameters, dimensions for some basic parts were chosen based on calculation, while others are standard parts. In the end, a CAD model and technical documentation were made.
