Description
lV9~ 26 This invention relates to means for the cooking of foodstuffs often known as greaseless frying.
The invention deals with the cooking of foodstuffs exposed to a heated gas which is heated and impelled through a housing wherein thare is a rotatable container containing the foodstuffs.
The most relevant prior art known to applicant is Canadian Patent 887,585 to Vogt. This patent shows apparatus ~;
for greaseless cooking including an impeller or the gas at the top of a housing. A bell is located inside and spaced from the walls of the housing. The food to be cooked is located to be tumbled inside the bell. The impeller is located over an opening at the upper end of the bell and draws the gases up through the bell and drives it downwardly between the bell and walls o~ the housing. The gases are hea~ed. The arrangement of Vogt has numerous disadvantages. Location of the impeller over the rising heated gases from the food is extremely deleterious `
to the impeller bearings, and parts, and the motor windings and wiring shortens the life of these members. Location o~ the oodstuffs in the bell renders the insertion and removal of the foodstuffs inconvenient. The Vogt apparatus, moreover, is thought to be unhygenic, for practical purposes, since the ~ell is nearly impossible to clean.
This invention, in one facet, provides a housing with a `
food container rotatably mounted therein about an axis which is ;`~
more horizontal than vertiaal and apertures in the container so ~hat heated gases may be circulated through the container, an impeller for causing such circulation of the yases laterally disposed from the container and means for heating the gases impelled by the impeller. The lateral disposal of the impeller ~ 4S~2~ ~-relative to the ~ood containe~ means that ~he hottest gases rising from the food~tufs do not do equivalent damage to the impeller, motor, be~rings and parts. Mor00ver, the lateral disposal of the impeller, relative to the food container, provides, in the whole unit, a low profile suitable for convenient location on a counter or table in a restaurant or e~uivalent food dispensing location.
The device is relatively easy to clean compared to the bell arrangement of Vogt.
Tha invention, in another facet, provides a rotatably ;
mounted food container, apertured to allow the passage of gase~
therethrough wherein the rotatably mounted food container is supported so as to be easily withdrawn (between cooking operations) through a wall of the housing. The rotatable container iæ provided with cover means which close the removal aperture in the housing when the container is in place. Tkis facet of the invention therefore provides a convenient and efficient means for insertion and removal of successive batches of the foodstuffs to be cooked.
In drawings which illustrate preferred embodiments of the invention :
Figure 1 shows a partially broken away perspective view of one form of the invention;
Fignre 2 is a diagramatic sectional side view of the device of Figure l;
Figure 3 is a partially broken away perspective view ;
of another form of the invention; and Figure 4 is a diagramatic sectional side view of ~he form of the invention shown in Figure 3.
In the drawings, a housing 11 defined by side top and , ~ ~04S9~; ~ ~ ~
end walls is pxovided at one lat~ral end with a cylindrical cooking area d~fined by cylindrical wall 10 and the rear ~ide wall of the houslng, (the axis of the cylinder being horizontal~
and at the oth~r end with ya~ impellers, here centrifugal fans 14. An opening 15 extends most of the length o the top of the cylindrical wall lO and a duct 12 i5 shaped to conduct gases passing upwardly through such opening to the input of the fans 14. The output of the fans i~ conducted through twin conducts 16 over heating elements 18 to a longitudinally ex-tending opening 17 in the side'of the cylindxical wall 10 belowthe centre line. Obviously the twin conducts 16 may be replaced by a single conduit or the twin fans by a sinyle fan, ~ -or both. The front end of the cylindrical area defined by wall 10 is open and at the opposite end a rotor drive, powered by a suitable electxic motor l9, drives a shaft defining at its end khe socket 20 for coupling to the food container. The food con~ainer has apertured sides~ preferably, a wire meshO The construction shown provides a frame 24, square, when viewed ~
~rom the front, having open sides and bottom and a mesh top ~``
covered with mesh 27 and an end wall with a stub pro~ection 22 to be received in and key to the rotor socket 20. ~lthough the frame is square with a drawer of complementary cross-section, it will be obvious that, the frame and its drawer may be made of round or polygonal or other shape. (Obviously the rotor driven end may be pro~ided with the stub and the frame with the socket or any alternate method of driving the frame may be used). The frame 24 is provided, at its outer end, with a rectilinear open end shaped 25 to allow a drawer to be slid into the frame open end, through the circular opening in the housing. A circular ~ plate 26 is mounted on the frame to surround the rectilinear . .
~o~s9~ l ,pening therein and plate 26 adapted to overlap the edges of the opening in the housing and to rest and rotate on two idler rollers 28 which are ro-tatably mounted on the casiny and grooved to receive the edge of the circular plate 26. It will be seen that the frame i5 supported for rotation by ~he stub 22 and -socket 20 at the inner end and, at the outer end, by the plate 26 and rollers 28. Further it will be seen that the frame 24 may be easily withdrawn for cleaning b~ lifting it of the rollers 28 .. ~ , and withdrawing the stub 22 fxom the socket 20, the latter ;~ ~ ;
connection being designed with a loose fit to aIlow such with-drawal.
A drawer t~pe cage 30 is formed to slide longitudinally into the frame. The cage 30 is provided with end walls 32 and 34 and with mesh 36 on the sides and bottom to form with the mesh ~
27 on the top of the frame 24 (when the drawer 30 is inserted `;~ ;
therein), a container for the foodstuffs when they are tumbled by rotation of the frame. The front end wall 34 of the drawer is dimensioned to overlap the inner edges of circular plate 26 to cover the entrance to the cooking area during the cooking opera-tion. A handle 40 is provided on the drawer to allow its easy removal and insertion of the foodstuffs. The handle ma~ be made collapsible or removable.
The heating of the gases by the heating elements is controlled in accord with a thermostat, not shown, having its sensor in the cooking compartment. The preerable mode of opera- ;
tion is for the thermostat to switch the heating elements on and of while leaving the fan running.
In operation, the device will most frequently be used with potato chips. The drawer 30 may be loaded with these and inserted in the frame 24 and the fan and heater operated while 59~6 the rotor rotates the frame 24 and drawer 30. We have found that, with potato chips, the temperature set~ing is, preferably between 4000F and 4600F, most Ruitably 440~F and that the ~
cooking of the batch in the drawer requires 4-10 minutes de- ~ -pending on the amount of the foodstuffs being cooked and the size of the individual pieces. We have found that best speed for the gases, is a speed of 20 metres/sec at the edge of the frame nearer the opening 17. Obviously no accurate figures can be given for the resultant turbulent flow in the container lQ and about the foodstuf~s and the frame. However our best estimate would be that such flow would be between 12 and 30 metres/second.
In the altexnative shown in Figures 3 and 4 the frame 24 and drawer 30 may be constructed in the same form as shown in Figures ~ and 2~ The housing is modified ~o provide for the gas flow as described hereafter. A centrifugal fan 40 is again located laterally from the food area but with its axis directed theretowards. A wall 42 divides the cooking area from the area containing fan 40. The wall 42 is provided with a central aperture 44 allowing gases from the cooking area to reach the central intake of fan 40. The cylindrical wall lo is omit~ed and the cooking area about frame 24 is defined by the housing walls and wall 42, as shown. The air impelled by fan 40 is cause~ to splral outwards as guided by the scroll-type guides 46 over heating elements 48. ~ower wall 50 is provided to guide the gases from fan 40 under wall 42 to enter the cooking area below frame 24.
The heat of 440F and frame impact ~elocity of the gases of approximately 20 metres/sec is preferred for this alternative also.
1(~4S926 In both embodimenks it will be seen that the air is supplied to the cooking ar2a below the air exit therefrom. ~ ~ ;
In both embodiments it will be noted that the housing may easily be de~igned to have a removable side for easy cleaning of the interior.
In both embodiments the unLoading and loading of successive batches i5 facilitated by the drawer construction.
The pxeferred embodiment shows a drawer-like container, de~igned to retain the foodstuf~s on all sides but its top, combining with a frame for the drawer whose mesh completes the means for retaining the food. It is an obvious alternative and well within the scope of the invention, to provide a drawer -~with two end walls, four mesh side walls and means ~or inserting and removing the ~oodstuffs ~rom the drawer. In such alter- ;
native the frame is just that without mesh. However it is believed ~hat this arrangement will not be found as convenient as the preferred embodiment.
The exteriorly visible portion o~ the drawer may be provided with an arrow or other indication to indicate when the drawer is right side up, for withdrawal; and drives are avàilable where the motor is automatically de clutched, when stoped, to allow the drawer to be rotated to the right side up position for withdrawal. Drives may also be provided which will always stop tne drawer rlght sids up.
