This non-provisional application claims the benefit of provisional application No. 67/174,961 filed on Jun. 15, 2015.
The present embodiment relates generally to systems for removing the use of hot cooking oil from deep fryers, and more particularly, to a system and method of removing and recycling the used oil from a deep fryer.
Cooking oil does degrade after a period of time due to continuous exposure to the atmosphere and various food constituents under elevated temperature conditions and must be discarded. When this occurs the waste oil is typically drained from the fryer, usually at elevated temperatures, into a container that is carried by hand to a disposal tank at the rear of the facility housing the cooking installation. The high temperatures of the oil expose the worker to possible burn in contact with the heated oil. During removal of the hot oil from the kitchen area, spilling frequently occurs with flow behind the equipment itself.
Conventionally, a variety of frying machines are used in frying sausages, chicken, crisps or potato chips, etc. in the open air. In particular, deep fryer oil fires are not uncommon and can cause substantial damage to a restaurant, including destruction of the entire building the restaurant is in. Of course, and any fire situation there is substantial risk to individuals near the fire. It is found disadvantageous for the workers being burned by the hot oil during transport the hot cooking oil from the kitchen fryer. Ideally, it would be desirable for the automatic removal of the hot oil from the deep fryer that reduces the possibility that the fire may spread beyond the deep fryer, and greatly reduces possibility of injury to kitchen workers and emergency personnel.
Therefore, there is a need for a system for removing oil from a deep fryer. Such a needed system would provide a drum covered by a sealable drum lid. Such a needed system would provide a hose having a first end connected to the drum lid and a second end having a nozzle. Moreover, such a needed system would provide a vacuum unit configured to generate suction through the second end of the hose toward the first end of the hose. Such a needed device would further have multiple uses, such as reducing possibility of injury to kitchen workers and emergency personnel etc. The present embodiment overcomes the shortcomings and accomplishes these critical objectives.
To minimize the limitations found in the existing systems and methods, and to minimize other limitations that will be apparent upon the reading of the specifications, preferred embodiment of the present invention provides a system for removing oil from a deep fryer that comprises a drum covered by a sealable drum lid, the drum lid having a top side and a bottom side, wherein the bottom side faces inside the drum. A hose having a first end is connected to the drum lid and a second end is having a nozzle. A vacuum unit is configured to generate suction through the second end of the hose toward the first end of the hose. The vacuum unit is mounted to the drum lid. The hose is composed of material capable of withstanding a temperature of at least 400 degrees Fahrenheit. The nozzle includes an inlet pipe secured to the second end of the hose via a hose clamp. Further, the drum lid is configured to removably seal to the drum via lockable spill prevention ring coupled with a weather sealed motor.
The oil removing system further includes a 90 degree inlet elbow adapter. The elbow adapter having an elbow first end and an elbow second end, wherein the first end is bolted to the drum lid. A barb nipple connected to the elbow second end of the elbow adapter. The first end of the hose is disposed about the barb nipple and secured to the barb nipple by a heat resistant hose clamp. An oil drop off pipe connected to the elbow first end of the elbow adapter through an oil drop hole in the drum lid.
In this embodiment, the oil removing system further includes a prevention safety valve and the drum lid that has a motor inlet hole. The prevention safety valve connects to the vacuum unit through the motor inlet hole. The oil removing system, further including a mobility dolly that includes at least one caster hard rubber wheel having a diameter of approximately 3 inches connected to an under side of the drum.

Turning to
The oil removing system 10 further includes a 90 degree inlet elbow adapter 38. The elbow adapter 38 is having an elbow first end 40 and an elbow second end 42, wherein the elbow first end 40 is bolted to the drum lid 16. A barb nipple 44 is connected to the elbow second end 42 of the elbow adapter 38. The first end 24 of the hose 22 is disposed about the barb nipple 44 and secured to the barb nipple 44 by a heat resistant hose clamp 46. An oil drop off pipe 48 is connected to the elbow first end 40 of the elbow adapter 38 through an oil drop hole in the drum lid 16.
In this embodiment, the oil removing system 10 further includes a prevention safety valve 50 and the drum lid 16 has a motor inlet hole 52. The prevention safety valve 50 connects to the vacuum unit 54 through the motor inlet hole 52. The oil removing system 10, further including a mobility dolly (not shown) that includes at least one caster hard rubber wheel 56 having a diameter of approximately 3 inches connected to an under side of the drum.
A method for removing and recycling the used oil from a deep fryer 12 in accordance with the preferred embodiment of the present invention is provided. The method is initiated by providing an oil removing system 10 having a drum 14, a hose 22 and a vacuum unit 54. The hose 22 is placed into an oil vessel of the deep fryer. Thereafter, activating the vacuum unit 54 to suction the used oil through a nozzle 28, then through the hose 22 and then into the drum 14 until the drum 14 becomes full. Then, the lid is removed from the drum 14 for transporting the full drum 14 to a biodiesel processor for beneficial reuse.
In accordance with a preferred embodiment, the motor 36 and pump mounts in the removable drum lid 16 of the vacuum unit 54 and powered by 110 volt power outlet and creates 110 CFM free air flow. The approximate dimensions of the high temperature vacuum hose is 1½ inches in diameter and six feet in length with a 12 inch metallic wand. In use, a 55 gallon vessel or drum is used to create a vacuum inside and is used to contain & confine the used and spent fryer oil that is vacuumed from the kitchen deep fryer. This component is crucial for containing the hot fryer oil to lessen or eliminate the chance of workers being burned by the hot oil and contains fryer oil for transport away from the kitchen deep fryer. In process the vacuum hose 22 mount onto the top of the removable drum lid 16 and are located on the top of the drum 14. The metallic wand is submerged into the used fryer oil and the drum pulls the used oil from the deep fryer and into the drum 14. When the drum 14 is filled with used fryer oil, the removable drum lid 16 is removed along with the high temperature hose to facilitate the removal of the fryer oil from the drum by means of a transport vacuum truck to be transported to a biodiesel processor (See
In this embodiment, the approximate dimensions of the cylindrical design drum 14 have a diameter of 23.5 inches, 33 inches high, and the dimension of at least one caster hard rubber wheel 56 having a diameter of approximately 3 inches diameter and are enclosed with a lock down removable lid. The lock down removable lid 34 is made of 16 gauge steel and has a liquid volume of 50 gallons.
The foregoing description of the preferred embodiment of the present invention has been presented for the purpose of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise form disclosed. Many modifications and variations are possible in the system of the above teachings. It is intended that the scope of the present invention not be limited by this detailed description, but by the claims and the equivalents to the claims appended hereto.
