Abstract
Abstract The disclosure pertains to a deep fat fryer and a method of cooking chicken using same in which the chicken and cooking oil are employed in a ratio on the order of one to two, respectively, as to weight, and are placed in a smooth walled generally cylindrical chamber of the fryer with the fryer being provided with band type electric heaters adjacent to but spaced from the lower end of the chamber and outside of same to provide hot side wall heat input. The chicken to be cooked is in dry breaded serving piece form, and at a temperature of about 45* F. It is cooked within a basket removably positioned in the chamber that seats on the chamber bottom above a special filter unit that also seats on the chamber bottom above a drain outlet and in a relatively cool area of the chamber. After the fat has been heated to approximately 400* F., the chicken is dropped in the fat and within the basket, lifted gently within the fat to separate the pieces, and allowed to brown until it has approximately a cornflake color, after which the chamber is closed for cooking under pressure conditions on the order of 14 to 15 psig. When the vessel is up to pressure, the current to the vessel heaters is turned off and 9 minutes after the vessel is closed, the chicken is removed to a holding oven. The fat is then reheated to the 400* F. temperature level for cooking the next batch in like manner. After approximately six batches the cooking oil is drained under pressure through the filter unit and is reapplied to the vessel with sufficient make up cooking oil to restore the original cooking oil amount for cooking like batches of chicken in like manner.

Claim 1
Independent Claim
313 words
A deep fat fryer comprising: a vessel defining a smoothed walled chamber proportioned to receive cooking oil and chicken serving pieces to be cooked in the approximate ratio of two to one, a drain opening at the bottom of said vessel, valve means for opening and closing said drain opening, a removable cover for closing off the top of said vessel, means for clamping said cover in closed relation to the vessel for cooking the chicken serving pieces under pressurized conditions, heater means about said vessel and spaced at a level above the level of the bottom of said vessel for heating cooking oil received in the chamber to a temperature range for cooking chicken serving pieces received in the oil when the oil is in the chamber, said heater means being exterior of said chamber, and filter means within said chamber and between the level of said heater means and the level of said vessel bottom for filtering cooking oil drained from said vessel before it passes through said valve means, and disposed to permit solids in the oil collect on its upper side, said filter means comprising a filter unit extending across said chamber and including filter paper through which the cooking oil is to pass on opening of said valve means to filter the cooking oil, and means for applying a differential pressure on the cooking oil when said valve means is opened for inducing cooking oil flow through said filter paper, said heater means being positioned in the spaced relation relative to said filter means to avoid charring of the solids collecting on the filter means when the oil is heated to said temperature range and yet drive off moisture from said paper to permit said filtering of the oil through said paper on opening of said valve means and application of the differential pressure to the cooking oil.
Claim 2

313 words
A deep fat fryer comprising: a vessel defining a smoothed walled chamber proportioned to receive cooking oil and chicken serving pieces to be cooked in the approximate ratio of two to one, a drain opening at the bottom of said vessel, valve means for opening and closing said drain opening, a removable cover for closing off the top of said vessel, means for clamping said cover in closed relation to the vessel for cooking the chicken serving pieces under pressurized conditions, heater means about said vessel and spaced at a level above the level of the bottom of said vessel for heating cooking oil received in the chamber to a temperature range for cooking chicken serving pieces received in the oil when the oil is in the chamber, said heater means being exterior of said chamber, and filter means within said chamber and between the level of said heater means and the level of said vessel bottom for filtering cooking oil drained from said vessel before it passes through said valve means, and disposed to permit solids in the oil collect on its upper side, said filter means comprising a filter unit extending across said chamber and including filter paper through which the cooking oil is to pass on opening of said valve means to filter the cooking oil, and means for applying a differential pressure on the cooking oil when said valve means is opened for inducing cooking oil flow through said filter paper, said heater means being positioned in the spaced relation relative to said filter means to avoid charring of the solids collecting on the filter means when the oil is heated to said temperature range and yet drive off moisture from said paper to permit said filtering of the oil through said paper on opening of said valve means and application of the differential pressure to the cooking oil.
Claim 3
Dependent Claim
48 words
The fryer set forth in claim 1 wherein: said filter unit further comprises a pair of upper and lower foraminous plates between which said filter paper is positioned, with said filter unit upper plate being disposed about three-fourths of an inch below the level of said heater means.
Claim 4
Dependent Claim
213 words
A deep fat fryer comprising: a vessel defining a smoothed walled chamber proportioned to receive cooking oil and chicken serving pieces to be cooked in the approximate ratio of two to one, a drain opening at the bottom of said vessel, valve means for opening and closing said drain opening, a removable cover for closing off the top of said vessel, means for clamping said cover in closed relation to the vessel, heater means about said vessel and spaced above the bottom thereof for heating cooking oil received therein, said heater means being exterior of said chamber, and filter means between said heater means and said vessel bottom for filtering cooking oil drained from said vessel before it passes through said valve means, and disposed to permit solids in the oil collect on its upper side, said filter means including filter paper through which the cooking oil is to pass to filter same, said heater means being positioned relative to said filter means to avoid charring of the solids collecting on the filter means and yet drive off moisture from said paper to permit filtering through said paper, and means for supplying gas under pressure to said chamber for draining the oil from the vessel through said filter paper under fluid pressure conditions.
