Filtering system for deep fat cooking vessel

Claim 1

A filtering system for cooking oil heated to high temperatures in a deep fat cooking vessel, said system comprising: first and second conduit means for filtering means for cooking oil to and from said cooking vessel, a first filtering means including a first filtering media for receiving said cooking oil from the second of said conduit means and for removing particles from said cooking oil above a predetermined intermediate size by collecting said particles, said first filtering media comprising a cord characterized by a fibrous exterior, said cord being wound in an overlapping weave, a second filtering means for receiving cooking oils as filtered by the first filtering means and in fluid communication therewith, said second filtering means having a filtering media comprising a multilayer roll of thin, fibrous, paper material presenting interlocking fibers between layers, said second filtering means including means for directing said cooking oil axially of said roll substantially along the layers thereof, said second filtering means comprising a cylindrical metal container having a cylindrical sidewall and first and second ends joined to said sidewall at longtitudinally upstanding crimped edges, said container being closed to the flow of fluid to be filtered except for a plurality of perforation means within the first end of said cylindrical container, and fluid inlet connection means proximate said first end and centrally located thereof, said fluid inlet connection means communicating with a central core within said cylindrical container, said core providing fluid communication to a point proximate the second end of said container, the second end of said container having means to support said filtering media within said container and a portion rounded outwardly from inside said longitudinally upstanding crimped edges to provide for the flow of fluid from said point proximate the second end of said container in a radial direction therefrom, and screen means within said container adjacent said first end for support of said filtering media at said first end, said filtering media of said second filtering means being located peripherally around said central core and supported between said means to support said filtering media and said screen means, and a pump pumping fluid into said central fluid inlet connection means and into said central core and to said point proximate the second end of said container whereby said fluid passes radially therefrom and then upwardly through said filtering media and through said perforation means within the first end of said container, and is returned to said cooking vessel by said first conduit means coupling said first and second filtering means with said cooking vessel for return of oil thereto.
