Description
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a deep fryer with dual conveyors and more particularly pertains to deep frying foods continuously and automatically with a dual conveyor assembly.
Description of the Prior Art
The use of deep fat fryers is known in the prior art. More specifically deep fat fryers heretofore devised and utilized for the purpose of frying foods in a container of hot fat are known to consist basically of familiar, expected, and obvious structural configurations, notwithstanding the myriad of designs encompassed by the crowded prior art which has been developed for the fulfillment of countless objectives and requirements.
By way of example, U.S. Pat. No. 3,826,184 to Shotten Jr. discloses a conveyor-type cooking device.
U.S. Pat. No. 4,478,140 to Bullock discloses a fryer with oil circulation and conveyor.
U.S. Pat. No. 5,065,670 to Leiweke discloses a conveyor for dougnut fryer.
U.S. Pat. No. 5,074,199 to Miller discloses a deep fat fryer witch upwardly and downwardly movable conveyor and heating apparatus.
U.S. Pat. No. 4,379,055 to Carlson discloses an apparatus for the drip dry conveyance of oil-fried dough products.

The first driving sprocket functions to drive the input end of the primary conveyor. A second driving sprocket is positioned at the output end of the primary conveyor, the second driving sprocket functioning to drive the output end of the primary conveyor. The intermediate extent of the primary conveyor extends into the hot cooking liquid. The secondary conveyor has a receiving end and a dispensing end, the receiving end of the secondary conveyor positioned adjacent to the output end of the primary conveyor. The secondary conveyor functions to receive food items from the primary conveyor. A drive means includes a motor, the motor serving to drive the first and second driving sprockets and the primary conveyor. The motor also serves to drive the secondary conveyor. A heating element is positioned under the bottom wall of the rectangular container, the heating element functioning to control the temperature of the hot cooking liquid. A lid is hingedly attached to one of the side walls of the rectangular container. A plastic food warmer is secured adjacent the dispensing end of the secondary conveyor, the plastic food warmer functioning to temporarily store cooked food items. An input tray is secured adjacent the input end of the primary conveyor, the input tray functioning to hold pots and canisters that contain food items and condiments.

The primary conveyor 40 has an input end 45, an output end 50, and an intermediate extent 55 therebetween. A first driving sprocket 47 is positioned at the input end 45 of the primary conveyor 40. The first driving sprocket 47 drives the input end 45 of the primary conveyor 40. A second driving sprocket 49 is positioned at the output end 50 of the primary conveyor 40. The second driving sprocket 49 drives the output end 50 of the primary conveyor 40. The intermediate extent 55 of the primary conveyor 40 extends into the hot cooking liquid 25.
The secondary conveyor 60 has a receiving end 65 and a dispensing end 70. The receiving end 65 of the secondary conveyor 60 is positioned adjacent to and beneath the output end 50 of the primary conveyor 40. The secondary conveyor 60 receives food items from the primary conveyor 40 and delivers it to exterior of the container 20.
The drive means 80 includes a motor 85. The motor 85 serves to drive the first and second driving sprockets 47 and 49 as well as the primary conveyor 40. The motor 85 also serves to drive the secondary conveyor 60.
The heating element 90 is positioned under the bottom wall of the rectangular container 20. The heating element 90 functions to control the temperature of the hot cooking liquid 25.
The lid 100 is hingedly attached to one of the side walls of the rectangular container 20.
The plastic food warmer 105 is secured adjacent the dispensing end 70of the secondary conveyor 60. The plastic food warmer 105 functions to temporarily store cooked food items and to retain the heat therein.
The input tray 110 is secured adjacent the input end 45 of the primary conveyor 40. The input tray 110 holds pots and canisters that contain food items and condiments. Apertures in the tray allow canisters to be held therein.
The control means 115 is positioned under the bottom wall of the rectangular container 20 adjacent the heating element 90. The control means 115 controls the drive means 80 and heating element 90. The heating element may be of any variety including gas, electric, even charcoal, etc.
As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
