Vacuum frying device and method for using the same
View Patent ↗A method of converting a conventional atmospheric frying device to a vacuum frying device is provided. The method includes positioning a hood on top of a conventional frying device to provide an enclosure for drawing a vacuum within the modified devices. In addition, the method can include strengthening the existing vat so that it is capable of withstanding the forces associated with vacuum frying.
1. A frying device comprising:
a hood defining a basket receiving area and having an opening, wherein the hood is configured to receive a tube connected to a vacuum device, the tube being in fluid connection with the basket receiving area, wherein the vacuum device is configured to reduce the air pressure in the basket receiving area;
a vacuum measuring device configured to measure the vacuum in the basket receiving area;
an oil receiving area located below the basket receiving area;
a door configured to be movable between a first position not covering the opening in the hood and a second position covering the opening in the hood, wherein the frying device is operable as an atmospheric frying device when the door is in the first position;
a seal positioned between the door and the hood;
a basket;
a mechanism configured to move the basket from the basket receiving area to the oil receiving area;
at least one arm member or at least one chain member in operative communication with the mechanism configured to selectively move the basket between the basket receiving area and the oil receiving area, wherein the at least one arm member or the at least one chain member are positioned within the area defined by the basket receiving area and the oil receiving area when the door is in the second position covering the opening in the hood.
2. The frying device of claim 1 , wherein the mechanism for moving the basket comprises two sprockets attached to a rod, wherein the at least one chain member is coupled to the sprockets.
3. The frying device of claim 2 , wherein the mechanism further comprises a lever located on an external surface of the frying device, the lever being configured to rotate the two sprockets.
4. The frying device of claim 1 , wherein the hood can be removed to operate the frying device at atmospheric frying conditions.
5. The frying device of claim 1 , wherein the oil receiving area is defined by a metal container that is capable of withstanding a vacuum of at least 28 inches of Hg.
6. A system for converting an atmospheric frying device to a vacuum frying device, the system comprising:
a hood with front and bottom sides, the hood having an opening in the front side and an opening in the bottom side, the hood further comprising a door that is movable between a first position where the door does not cover the opening in the front of the hood and a second position where the door covers the opening in the front of the hood, wherein the frying device is operable as an atmospheric frying device when the door is in the first position, wherein the area formed by the hood defines a basket receiving area and the hood is configured to be received on a top surface of the atmospheric frying device with the opening on the bottom facing an oil receiving area of the atmosphere frying device, wherein the hood is configured to receive a tube connected to a vacuum device, the tube being in fluid connection with the basket receiving area, wherein the vacuum device is configured to reduce the air pressure in the basket receiving area;
a vacuum measuring device configured to measure the vacuum in the basket receiving area;
a seal positioned between the door and the hood;
a basket;
a mechanism configured to selectively move the basket from the basket receiving area to the oil receiving area;
at least one chain member in operative communication with the mechanism configured for selectively moving the basket between the basket receiving area and the oil receiving area, wherein the at least one chain member is positioned within the area defined by the basket receiving area and the oil receiving area when the door is in the second position covering the opening in the hood.
7. The system of claim 6 , further comprising a seal positioned on the bottom side of the hood.
8. The system of claim 6 , further comprising:
a vat configured to withstand a vacuum of at least 28 inches of Hg, the vat being configured to replace an existing vat on the atmospheric frying device.
9. The system of claim 6 , further comprising:
a strengthening member configured to strengthen an existing vat on the atmospheric frying device so that the strengthened vat can withstand a vacuum of at least 28 inches of Hg.
10. The system of claim 6 , wherein the mechanism for moving the basket comprises two sprockets attached to a rod, wherein the at least one chain member is coupled to the sprockets.
11. The system of claim 10 , wherein the mechanism further comprises a lever located on an external surface of the frying device, the lever being configured to rotate the two sprockets.
