Abstract

Abstract A method of continuously producing an expanded food stuff, which comprises entraining a material food stuff in a pressurized heated gas stream in a suspended condition, thereby heating and conveying said material, and then discharging the heated material into a gas atmosphere at a lower pressure, whereby said material is expanded. An apparatus for practicing the above-described method, which comprises a conduit for flowing a pressurized heated gas therethrough, means for introducing a material food stuff into the stream of said gas in a suspended condition to be entrained therein, means for collecting the heated material and means for discharging the heated material abruptly into a gas atmosphere at a lower pressure thereby to expand said material.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 162 words
An apparatus for continuously expanding a food stuff comprising, a source of heated and pressurized gas, a conduit connected at one end to said source for continuously flowing said heated, pressurized gas therethrough, a mixer in communication with said conduit downstream of said gas source in the direction of gas flow for continuously introducing said food stuff into said heated, pressurized gas, and a separating means downstream of said conduit in communication therewith for continuously separating said heated food stuff from said gas and continuously collecting said food stuff, and means in communication with said separating means for abruptly discharging said collected food stuff into air at a lower pressure than said gas, the length of said conduit between said mixer and said separating means and the flow rate of the gas and food stuff through said length being sufficient so that the food stuff introduced at said mixer is fully heated and pressurized by said gas before reaching said separating means.
Claim 2
Independent Claim 162 words
An apparatus for continuously expanding a food stuff comprising, a source of heated and pressurized gas, a conduit connected at one end to said source for continuously flowing said heated, pressurized gas therethrough, a mixer in communication with said conduit downstream of said gas source in the direction of gas flow for continuously introducing said food stuff into said heated, pressurized gas, and a separating means downstream of said conduit in communication therewith for continuously separating said heated food stuff from said gas and continuously collecting said food stuff, and means in communication with said separating means for abruptly discharging said collected food stuff into air at a lower pressure than said gas, the length of said conduit between said mixer and said separating means and the flow rate of the gas and food stuff through said length being sufficient so that the food stuff introduced at said mixer is fully heated and pressurized by said gas before reaching said separating means.
Claim 3
Dependent Claim 26 words
The apparatus of claim 1 further including a means for guiding the gas exiting from said separating means to a place of use for said gas.
