    Build Oil
AI Thread Summary
To build a food oil expeller, a foundational understanding of mechanical engineering principles is essential, particularly in processes like crushing seeds under pressure and applying heat. Different extraction methods may be required depending on the type of seeds and desired oil quality. Techniques such as using super-heated steam can also be effective for extraction. It's important to consider the intended use of the extracted oil, as this may influence the design and functionality of the expeller. Engaging with knowledgeable individuals in mechanical engineering can provide valuable insights for this project.

Hi all!
I am new to this forum and i know nothing about mechanical engineering.I have degrees in electrical engineering and computer science.I wish to build a food oil expeller and want to know the mechanical engineering basics i need to study before i venture on the project.Any pointers will be greatly appreciated.
thankyou

not understand your question..
food oil expeler?
waste vegitable oil?
expel what?
 
hello Ranger mike,thank you for your reply.I want to extract food oil from ,say, vegetables oil seeds.
 
thanks
i am out of my area on thsi one
good luck
 
Welcome to PF, Bineyame.
I think that different types of processes are used depending upon the specifics of the seeds involved and what the end result is to be. Crushing them under extreme pressure, possibly with heat added, is one way. Attacking them with super-heated steam might also be effective.
 
question - wha t yo u going to do with the oil when you get it?

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
