Abstract

An elongated open top tank containing water, one end being a loading end, and the opposite end being an exit end. Positioned transversely across the tank, spaced generally along the full length above the water line, are water distribution lines each having multiple water outlet nozzles aiming downward and at an angle toward the exit end of the tank. The distribution lines are connected to an output side of a high volume water pump used to circulate the tank water. The water pump draws water from the exit end of the tank so that during pumping, a strong current is created in the tank as the nozzles re-apply the water. Positioned transversely within the tank is a plurality of solid baffles, some positioned high in the water, and some positioned low in the water in a staggered arrangement. Produce deposited at the loading end of the tank is sprayed by the nozzles and drawn by the strong current. The current and nozzle output in conjunction with the high and low baffles forces the produce completely underwater in order for it to move underneath the bottom edge of the high baffles and over the top edge of the low baffles. The produce is moved in an agitating serpentine pattern as it moves toward the exit end of the tank to where an open screen conveyor is located in part in the water to lift the cleaned produce from the tank.

Claims2

Dependent claims

A produce washer comprising an elongated open top tank containing water, a first end of said tank being a loading end whereat produce is first introduced into said produce washer for cleaning, and an oppositely disposed second end of said tank being an exit end whereat cleaned produce is removed from the tank;

a water circulation pump connected to draw water from within said tank from said exit end, said pump further connected to return the drawn water to said tank through a plurality of water output nozzles positioned along said open top of said tank, said output nozzles aiming downward into the water within said tank so that the water from said nozzles will strike produce floating in the water within said tank and push the produce underwater, the drawing of said water and re-applying of the water via said pump and nozzles arranged for creating a current within the water within said tank with said current moving from said loading end toward said exit end of said tank, said current being sufficiently strong to move produce within the water in said tank from said loading end toward said exit end;
a plurality of upper baffles positioned transversely within said tank and in spaced relationship to one another, said upper baffles extending downward within said water contained within said tank and terminating prior to reaching a bottom of said tank so as to provide space between a bottom edge of each upper baffle and the bottom of said tank for said current and the produce to pass thereunder,
a plurality of lower baffles positioned transversely within said tank and in spaced relationship to one another, said lower baffles extending upward from said bottom of said tank within said water contained within said tank and terminating prior to reaching a top surface of said water within said tank so as to provide space between a top edge of each lower baffle and the top surface of said water for said current and the produce to pass thereover, said lower baffles positioned in between and in spaced relationship to said upper baffles so as to define a serpentine channel through which said current travels and carries produce in the process of washing the produce.

A produce washer comprising an elongated tank containing water, a first end of said tank being a loading end whereat produce is first introduced into said water of said produce washer for cleaning, and an oppositely disposed second end of said tank being an exit end whereat cleaned produce is removed from said tank;

a water circulation pump connected to draw water from within said tank from said exit end, said pump further connected to return the drawn water to said tank through a plurality of water output nozzles, said plurality of water output nozzles aiming into the water within said tank so that the water from the nozzles will strike produce within the water of said tank and impart motion in the produce, the drawing and re-applying of the water via said pump and said plurality of water output nozzles arranged for creating a current within the water within said tank with said current moving from said first end toward said second end of said tank, said current being sufficiently strong to bias the produce within the water in said tank toward moving from said first end toward said second end;
a plurality of individual substantially water impervious baffles positioned within the water within said tank, said baffles in spaced relationship to one another, said baffles extending within the water within said tank and terminating so as to provide space beyond a terminal edge of each baffle within the water for said current and the produce to pass through,
the plurality of baffles placed with the terminal edges thereof positioned under the water within said tank and relative to said first and second ends of said tank to define a serpentine path through which said current must travel, the plurality of baffles defining the serpentine current path having said terminal edges positioned so as to require at least periodic complete submergence of produce traveling the serpentine current path,
the nozzles of said plurality of water output nozzles placed along said elongated tank with at least one nozzle of said plurality of water output nozzles positioned proximal to each baffle of the plurality of baffles so that water output from the nozzles will strike the produce and impart motion therein to aid in moving the produce being drawn by said current to move beyond the terminal edges of the baffles when drawn by said current from said first end toward said second end of said produce washer.
