Claim 1
Independent Claim
320 words
An apparatus for debittering soybeans and the like to destroy and extract the bitter taste therefrom comprising frame means, an open topped generally rectangular processing tank supported by said frame means, exhaust hood means arranged thereabove, inlet and discharge conduits for introducing and flowing water preheated to approximately 198° F. into and lengthwise through and from said tank, at least three vertically spaced treatment zones in said tank, spaced steam manifolds in each of said zones adjacent the bottom thereof, water injector conduits interposed between said steam manifolds, sprocket means on said frame at the inlet and discharge ends of said tank, chain conveyor means traveling over said sprockets and into and through said tank, a series of baskets for receiving soybeans to be treated on said conveyor means and depending downwardly therefrom, means for indexing said sprockets and successively and intermittently moving said baskets through and immersing the baskets and beans therein in the water in said treatment zones, injecting steam at an approximate temperature of 214° F. into the first zone so that steam will bubble up through and render the water turbulent and penetrate the skins of and expand and rupture the beans and destroy the enzymes on the outer surfaces thereof to enable the volatile oil and gases to escape with the exhausting steam through said exhaust hood, injecting water and steam through said water injector conduit and steam manifold in said second zone at a reduced temperature of approximately 212° F. as a filled basket enters that zone to render the water turbulent therein, and introducing water and steam through said water injector conduit and steam manifold in said third zone as a filled basket enters thereinto at the same temperature of approximately 212° F. as in said second zone whereby remaining volatile gases and oils will be released into the turbulent water therein and will be exhausted by the steam through said exhaust hood.

An apparatus for debittering soybeans and the like to destroy and extract the bitter taste therefrom comprising frame means, an open topped generally rectangular processing tank supported by said frame means, exhaust hood means arranged thereabove, inlet and discharge conduits for introducing and flowing water preheated to approximately 198° F. into and lengthwise through and from said tank, at least three vertically spaced treatment zones in said tank, spaced steam manifolds in each of said zones adjacent the bottom thereof, water injector conduits interposed between said steam manifolds, sprocket means on said frame at the inlet and discharge ends of said tank, chain conveyor means traveling over said sprockets and into and through said tank, a series of baskets for receiving soybeans to be treated on said conveyor means and depending downwardly therefrom, means for indexing said sprockets and successively and intermittently moving said baskets through and immersing the baskets and beans therein in the water in said treatment zones, injecting steam at an approximate temperature of 214° F. into the first zone so that steam will bubble up through and render the water turbulent and penetrate the skins of and expand and rupture the beans and destroy the enzymes on the outer surfaces thereof to enable the volatile oil and gases to escape with the exhausting steam through said exhaust hood, injecting water and steam through said water injector conduit and steam manifold in said second zone at a reduced temperature of approximately 212° F. as a filled basket enters that zone to render the water turbulent therein, and introducing water and steam through said water injector conduit and steam manifold in said third zone as a filled basket enters thereinto at the same temperature of approximately 212° F. as in said second zone whereby remaining volatile gases and oils will be released into the turbulent water therein and will be exhausted by the steam through said exhaust hood.
Claim 3
Dependent Claim
64 words
An apparatus as set forth in claim 1, wherein said sprocket means each includes a pair of spaced sprockets arranged on shafts extending transversely of said frame and each includes radial arms recessed at the ends thereof, said conveyor means includes endless linked chains traveling over and engaging said recessed arms, and said conveyor baskets extending transversely between and connected to said chain links.
Claim 4
Dependent Claim
68 words
An apparatus as set forth in claim 1, wherein said indexing means successively and intermittently rotates said sprocket means in increments of one sixth a revolution each to successively introduce said conveyor and baskets into said treatment zones whereby the beans therein are successively heated and treated by the turbulizing steam injected thereinto and rising through the water therein, and the treated beans are removed from said tank.
Claim 5
Dependent Claim
46 words
An apparatus as set forth in claim 3, wherein timing means is associated with and controls said sprockets whereby each of the baskets with beans therein remains in each of said zones for approximately one minute and the total processing time involves at least three minutes.
Claim 6
Dependent Claim
49 words
An apparatus as set forth in claim 1, wherein said steam manifolds include parallel branched apertured conduits whereby steam emerging therefrom bubbles upwardly through the water in each of said zones and renders it turbulent so that the beans are separated and caused to roll around furing their treatment.
