Abstract
A recirculating hot oil cooking apparatus for animal or vegetable product pieces which includes flow direction altering mechanisms in front of and behind the product entry zone of the cooker to substantially eliminate eddy currents and improve movement of raw product pieces from the product entry zone toward the product exit zone without product clumping.
Claims19
In a recirculating hot oil cooking assembly for animal and vegetable product pieces,
- an elongated pan assembly having front, rear, bottom, and side walls for containing a volume of hot oil flowing between a product entry zone located near said front wall and adapted to receive said product pieces in raw form and a product exit zone located near said rear wall and adapted to discharge said product pieces after cooking;
- a sump formed in the bottom of said pan near said product exit zone for withdrawing oil from said pan assembly;
- an inlet header assembly for supplying hot oil to said pan assembly at said product entry zone including an inlet feed jet extending substantially across said front wall of said pan assembly underneath the surface of said volume of oil to supply a substantially uniform stream of oil at a substantial velocity across a surface region of said product entry zone;
- a pump and heat exchanger assembly coupled between said sump and said inlet header for recirculating reheated oil therebetween to establish said flowing volume of hot oil in said pan assembly;
- and
- flow directing means mounted adjacent said product entry zone of said pan assembly for repetitively altering the localized flow direction of said volume of hot oil to reduce recirculating eddy currents in said oil in said product entry zone, said flow directing means comprising a plurality of fin means positioned at spaced preselected non-normal orientations behind the product entry zone and movable so as to achieve said repetitively alternating localized flow of said hot oil while reducing eddy currents in said oil, said flow directing means additionally including means to repetetively move said fins for such purpose, whereby improved movement of said product pieces away from said product entry zone towards said product exit zone is produced to reduce clumping of raw product pieces in said product entry zone.

- an inlet header assembly for supplying hot oil to said pan assembly at said product entry zone and including an inlet feed jet extending across substantially the full width of said front end wall of said pan assembly underneath the surface of said volume of oil to supply a substantially uniform stream of oil at a substantial velocity across said product entry zone;
- a pump and heat exchanger assembly coupled between said sump and said inlet header for recirculating reheated oil therebetween to establish said flowing volume of hot oil in said pan assembly;
- a first flow directing assembly mounted at the rear of said product entry zone, said first flow directing means comprising a plurality of fin means positioned at spaced preselected non-normal orientations behind said product entry zone so as to repetitively alter the localized flow direction of said volume of hot oil thereat, said first flow directing means including means to repetitively move the same for such purpose;
- and
- a second flow directing assembly mounted adjacent said inlet feed jet, said second flow directing means also comprising a plurality of fin means positioned at spaced preselected non-normal orientations adjacent the inlet feed jet and movable so as to repetitively alter the flow direction of said inlet stream of oil across said product entry zone, said second flow directing means likewise including means to repetitively move the same for such purpose, said first and second flow directing assemblies cooperating to eliminate recirculating eddy currents in said product entry zone, whereby consistent movement of said vegetable product pieces away from said product entry zone towards said product exit zone is produced to reduce clumping of raw product pieces in said product entry zone.
