Description

APPLIANCE AND METHOD FOR COOKING FOOD ARTICLES
Inventors: Ruben MASEL and George VALDSHTEIN
FIELD AND BACKGROUND OF THE INVENTION
The present invention relates to an appliance and method for cooking food
articles, and particularly to such an appliance and method for cooking food articles
by means of a heated cooking liquid. The invention is especially useful as an
appliance for either frying various types of food articles, such as potatoes and pieces
of meat, for steaming food such as rice or vegetables, and/or for popping corn.
Many appliances of this type have been developed and are described in
the literature, for example in US Patent Nos. 4,873,920; 4,901,633; 5,010,805;
5,146,841; 5,165,329; 5,379,684; 5,524,527; 5,543,166; 5,584,234; 5,611,265;
and 6,077,555. In most of these appliances, the food articles are completely
immersed in hot oil during the frying process, thereby causing them to become
soaked in the oil. Patent 5,543,166 discloses an appliance in which the food
articles are tumbled through a small quantity of the frying oil at the bottom of a
rotary drum in order to decrease the quantity of oil absorbed by the food articles.
However, even with the latter appliance, the food articles still absorb a significant
quantity of the oil, in the order of 20%. OBJECTS AND BRIEF SUMMARY OF THE INVENTION
An object of the present invention is to provide an appliance, and also to
method, which may be used for frying food articles while minimizing the quantity
of oil absorbed by the food articles.
According to a broad aspect of the present invention, there is provided a
cooking appliance for cooking food articles by means of a heated cooking liquid,
comprising: a liquid container for receiving a quantity of the cooking liquid; an
electrical heater for heating the cooking liquid; a perforated rotary drum for
receiving the food articles to be cooked; and a drive for rotating the rotary drum;
characterized in that the liquid container is selectively movable to a raised
position, wherein the cooking liquid therein directly contacts food articles in the
drum, or to a lowered position wherein the cooking liquid therein is spaced below
the food articles in the drum.
According to another aspect of the present invention, there is provided a
method of cooking food articles comprising introducing the food articles into a drum
perforated with openings smaller than the food articles; introducing a cooking liquid
in a liquid container below the drum; spacing the drum above the liquid container
sufficiently such that the cooking liquid therein does not directly contact any food
articles in the drum; and heating the cooking liquid while rotating the drum such
that the food articles tumble within the drum while heated by the heat from the
cooking liquid and the liquid container. As will be described more particularly below, such a cooking appliance
may be used for both frying food articles and also for steaming food articles.
When the appliance is used for frying food articles, the liquid container is
first moved to its lowered position, wherein the cooking liquid therein is spaced
below the food articles in the drum. In the lowered position of the liquid
container, the heat from the hot oil and the liquid container pre-heats the food
articles as they tumble in the drum, thereby raising their temperature such as to
reduce the temperature difference between the food articles and the hot oil at
the time of initial contact of the food articles with the hot oil. The pre-heating is
effected not only by the heat transferred from the hot oil, but also by that
transferred from the heated walls of the container. It has been found that this
pre-heating substantially reduces the amount of oil absorbed by the food articles,
from about 20% as in the previous process, to about 8 - 11%. It is believed that
this result is produced for the following reasons: When the food articles are not
pre-heated, there is a large temperature difference between the food articles and
the oil at the time of the initial contact with the oil, which cools the relatively
small quantity of oil. This delays the formation of a hardened crust by the hot oil,
and thereby increases the amount of oil absorbed and retained within the food
articles before the crust is formed. On the other hand, when the food articles are
pre-heated before immersed in the hot oil, the oil remains hot and therefore
immediately forms a crust, which thereby reduces the amount of oil absorbed
before the crust is formed. Such a cooking appliance can also be used for steaming food articles,
such as vegetables, rice, etc., by retaining the liquid container in its lowered
position, spaced below the bottom of the drum while the drum is rotated, so that
the food articles tumbling within the drum do not come into direct contact with
the liquid (water), but only with the steam thereof.
Further features and advantages of the invention will be apparent from
the description below.

DESCRIPTION OF A PREFERRED EMBODIMENT
The preferred embodiment of the invention illustrated in the drawings is
a cooking appliance for use primarily for frying food articles, such as potatoes,
pieces of chicken, and the like, but which may also be used for other cooking
applications, including steaming food and the like.
The illustrated cooking appliance comprise a housing, generally
designated 1, open at its upper end. The upper end is closable by a lid 2 having
a handle 3. The lid 2 carries a pair of depending arms 4 for rotatably mounting a
drum 5 about a horizontal axis 5a. As will be described below, drum 5 is adapted
to receive the articles of food to be fried or steamed. It is perforated with a
plurality of openings 5b of a size to retain the food articles within the drum
during the rotation of the drum.
A liquid container 6 of slightly larger dimensions than the drum 5 is
removably supported within the housing 1 by a supporting member 7 disposed
below the container. Supporting member 7 also removably supports a plurality of
electrical heater elements 8, such as heater wires, halogen lamps, or the like,
below the bottom wall 6a of container 6. A reflector 9 is mounted below the
heating elements for reflecting the heat generated by the heating elements towards the bottom wall 6a of the liquid container. The outer surface of bottom
wall 6a may be blackened for this purpose.
The liquid container 6 is movable either to a lowered position wherein its
bottom 6a is spaced well below the bottom 5c of the rotatable drum 5, as shown
in Fig. 1, or to a raised position wherein its bottom 6a is but slight spaced from
the drum bottom 5c, as shown in Fig. 2. The raising and lowering of the liquid
container is effected by a rotatable screw 10 threadeadly received within a nut
11 on each of the two opposite sides of the container. The two nuts 11 are fixed
to the container support 7, whereas the two screws 10 are rotated by gearing 12
rotatably mounted on a supporting member 13 on the two opposite sides of the
bottom wail of housing 1. Gearings 12 are driven by electrical motor 14 via shafts
15 extending from the opposite sides of the electrical motor. Thus, motor 14 may
be rotated in one direction to lower the liquid container 6 with respect to the
drum 5, or may be driven in the opposite direction to raise the container with
respect to the drum.
Drum 5 is rotated about its horizontal axis 5a by a second motor 23
mounted at the lower end of the housing 1 and magnetically coupled to the
drum 5 via a magnetic coupling. For this purpose, the horizontal rotary shaft 5a
of drum 5 is formed with end flanges 16 at its opposite ends. To one end flange
16 is secured a disc 17 carrying a plurality of permanent magnetic elements 17a
(Fig. 6) located adjacent to the inner surface of the liquid container 6 in the
operative position of the drum. A second disc 18, also carrying a corresponding plurality of magnetic elements, is disposed adjacent to the outer face of the
liquid container 6 in alignment with a magnetic disc 17, such that the magnets of
the two discs effect a magnetic coupling through the liquid container without
piercing the liquid container. The liquid container 6 may be made of any suitable
non-magnetic material, such as aluminum or a special grade of stainless steel.
The outer magnetic disc 18 is coupled to the rotary motor 23 via a pulley
belt coupling, including a supporting member 19 mounting a pair of pulleys 20,
21 coupled together by a pulley belt 22. The lower pulley 21 is driven by
electrical motor 23 via a shaft passing through the pulley belt support 19.
It will be seen that the magnetic coupling, including the two
magnet-carrying discs 17, 18, located on opposite sides of the liquid container 6,
permits the drum 5 to be conveniently introduced into, or removed from, the
interior of the liquid container 6.
Fig. 5 illustrates a variation, wherein the illustrated appliance includes an
inner magnetic-carrying disc 27, and an outer magnetic-carrying disc 28, on the
opposite side of the drum 5 for purposes of balancing the drum during its
rotation, and also for facilitating its removal from the appliance.
Figs. 6 and 7 illustrate another modification that may be used for this
purpose. In this modification, each of the magnetic-carrying discs 17, 18, also
includes a plurality of low-friction spacer elements, shown at 37, 38, respectively,
for closely spacing the respective disc from the respective surface of the liquid
container 6. Fig. 7 also illustrates the magnets 39 carried by the disc 18. For purposes of opening the drum 5 in order to introduce food articles to
be cooked, or to remove such food articles after having been cooked, the drum 5
is constructed of a plurality of sections, as shown particularly in Fig. 8. Thus, the
drum 5 includes a main section 51, and two openable sections 52, 53 hingedly
mounted at 54 and 55, respectively to the main section 51. Section 53 of the
drum is provided with a tongue 56 having an inwardly-extending projection 57
received within a correspondingly-shaped recess (not shown) for retaining the
two hinged sections 52, 53 in closed positions, as shown in Fig. 8.
In order to open the drum, tongue 56 is grasped by the user's fingers
and pulled outwardly to unseat the projection 57, and thereby to permit the two
sections 52, 53 to be pivotted to their open positions.
The illustrated appliance may be used in the following manner:
The food articles are introduced into the drum 5 by first removing the
drum from the housing and opening the two hinged sections 52, 53. The drum
may be conveniently removed from the housing by merely grasping handle 3 and
lifting it with the lid 2 from the upper end of the housing.
If the food articles are to be fried, a small quantity of frying oil is
introduced into the liquid container 6 so as to form a shallow pool covering only
the bottom 6a of the container, as shown at 60 in Figs. 1 and 2. Initially, motor
14 is operated to lower the liquid container 6 such that the upper level 61 of the
pool of oil 60 on the bottom wall of the container is spaced well below the
bottom wall 5c of the drum 5, as shown in Fig. 1. Electrical motor 23 is then operated to rotate the drum 5 about its horizontal axis 5a, and the electrical
heaters 8 are energized to heat the bottom wall 6a of the liquid container.
As the drum 5 is rotated, the articles of food therein tumble within the
drum while heated by the heat from the oil 60 within the container 6. Since the
bottom portion of the drum 5c is spaced above the level 61 of the oil 60 within
the bottom 6a of the container 6, the oil does not directly contact the food
articles tumbling within the drum, but rather merely heat the food articles
indirectly as the food articles tumble within the drum. The food articles are thus
pre-heated by the hot frying liquid and the walls of the container 6.
After the food articles have thus been pre-heated, motor 14 is energized
to raise the liquid container 6 so that the level 61 of the frying oil 60 within the
bottom 6a of the container now partially immerses the bottom portion 5c of the
drum 5. Accordingly, as the drum is rotated by motor 23, the food articles tumble
into and out of the cooking oil 60 and thus are fried by the oil.
It has been found that pre-heating the food articles, before frying them,
causes a substantially smaller amount of frying oil to be absorbed by the food
articles. For example, it was found that when the food articles are potato sticks,
they absorb approximately 20% by weight of the frying oil when they are fried
without pre-heating, but only about 8 - 12% of the frying oil when pre-heated
and then fried as described above.
If the food articles are to be steamed, water, rather than frying oil, is
introduced into the bottom of the container 6 also to the level as shown at 61 in Fig. 1. While the container is in its lower position, the water does not directly
contact the food articles, as they tumble within the drum during its rotation, but
rather are only steamed by the water vapor produced by the electrically heated
water in the bottom of the container.
While the invention has been described with respect to several preferred
embodiments, it will be appreciated that these are set forth merely for purposes
of example, and that many other variations may be made. For example, the
drives for rotating the drum, and/or for raising the liquid container, may be
manual drives rather than electrical drives. In addition, the drum could also be
rotated at a relatively high speed after removal from the oil to spin-off any
excess oil. Further, to facilitate lifting the lid with the drum, it may be desirable
to provide a lever arrangement, particularly for the initial lifting movement to
overcome the magnetic forces. Also, it may be desirable to include a retainer for
retaining the oil container to its support to assure that it moves with its support.
Many other variations and applications of the invention will be apparent.
