Abstract
A deep fryer apparatus particularly suitable to home use with a rotatable basket rotating within tray. Both the basket and the tray can be removed from a fixed tray within the housing. The axis of rotation of the basket is greatly inclined with respect to an oil bath contained in tray, so that the food contained in the basket is cyclically and progressively immersed in the oil bath. The bath is heated by adequate heaters, and the apparatus is monitored by control devices. The new deep fryer features high overall performance and low operating costs. This is due in particular to the small quantity of oil needed to form the oil bath, which is about one-half what is generally necessary, and to the reduced cooking time required as a result of the progressive and repeated elimination of food moisture.
Claims32
A deep fryer, operable with a quantity of oil for cooking a quantity of food, comprising a housing defining a chamber therein for containing said quantity of oil which oil will have a top surface defining a horizontal plane, a perforated basket for holding said quantity of food rotatably mounted in said chamber, the basket being rotatable such that food in any part of the basket is cyclically and repeatedly moved to be below and then above said horizontal plane of said oil, the basket having a central axis of rotation and being rotatably mounted in said chamber with said central axis oblique relative to vertical, drive means in said housing for rotating said basket such that said food can be cyclically immersed and emersed in said oil, and means in said housing for heating the bottom of said chamber and said oil therein.
A deep fryer, operable with a quantity of oil for cooking a quantity of food, comprising a housing defining a chamber therein for containing said quantity of oil which oil will have a top surface defining a horizontal plane, a perforated basket for holding said quantity of food rotatably mounted in said chamber, the basket being rotatable such that food in any part of the basket is cyclically and repeatedly moved to be below and then above said horizontal plane of said oil, drive means in said housing for rotating said basket such that said food can be cyclically immersed and emersed in said oil, means in said oil therein said chamber having a bottom wall and a liquid-sealed rotary coupling extending through said wall with input and output parts below and above said wall respectively, and said drive means comprises an electric motor with an output shaft mounted in said housing below said bottom wall and coupled to said in out of said rotary coupling, said output of said rotary coupling being releasably engageable to said basket for rotating same.
A deep fryer operable with a quantity of oil, comprising:
- a housing, a fixed vessel within the housing for containing a quantity of oil which oil defines a horizontal top surface when the apparatus is positioned in upright position, a basket of generally cylindrical shape having a central axis and being positionable in said vessel with said central axis oblique from vertical, said basket adapted to be inserted in and removed from said vessel, said basket being rotatable while in said oblique position, said basket positioned in said vessel such that when said quantity of oil is present in said vessel, a portion of its bottom will be beneath said top surface of the oil and a diametrically opposite portion will be above said top surface of the oil, said basket, as it rotates, having each part of its bottom cyclically immersed and emersed from said oil, drive means in said housing for rotating said basket while in its oblique position, means in said housing for heating the bottom of said vessel and any oil therein, and a lid for covering and closing the top of said housing.
A deep fryer operable with a quantity of oil, comprising:
- a housing, a vessel fixed within the housing for containing said quantity of oil, a basket having a central vertical axis when in upright position, said basket being selectively positionable in said vessel in said upright position and in a second position with said central axis oblique from vertical, said basket adapted to be inserted in and removed from said vessel when said basket is in its upright position, said basket being rotatable while in said second position, drive means in said housing for rotating said basket when it is in its second position, heating means in said housing for heating the bottom of said vessel and said oil therein, and a lid for covering and closing the top of said housing.
