A garlic processor for processing a garlic clove having a husk includes a motor having a spindle, a cutting disk, disposed on the spindle and having cutting surfaces, and a cover, having a bottom opening, configured to removably mount with the bottom opening surrounding the cutting disk. The motor gives the cutting disk a rotational speed sufficient to both (i) remove the husk of a garlic clove which comes in contact therewith, and (ii) mash the garlic clove and fling particles thereof outwardly onto the inside surface of the cover.
Description
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates generally to food processing devices. More particularly, the present invention relates to a garlic processor which both separates the husk from a clove of garlic, and mashes the garlic.
2. Related Art
There are many devices for cutting, chopping, mashing, and otherwise processing food products. Many of these involve motorized cutting blades or wheels which can be configured in a variety of ways for producing a variety of cut configurations—e.g. shoestring potatoes, cucumber slices, and diced vegetables.
Some food materials, however, are difficult to process by machine, and are thus frequently prepared by hand, as has been done throughout history. Garlic is one such food item. Garlic is difficult to process because the bulb must first be broken, then the individual cloves must be peeled to remove the inedible husk. Only then can the garlic clove be cut or mashed to put it into a useable form. This process is tedious, labor-intensive, and tends to release large quantities of odor. All of these conditions can be objectionable.
SUMMARY OF THE INVENTION
It has been recognized that it would be advantageous to develop a garlic processor that reduces or eliminates hand labor associated with preparing garlic for use in food.
It would also be advantageous to develop a garlic processor that both separates the husk from the clove, and mashes the garlic.
It would also be advantageous to develop a garlic processor that reduces the amount of strong garlic odor that is released into the air during the processing of the garlic.
The invention advantageously provides a garlic processor for processing a garlic clove having a husk, comprising a motor having a spindle, a cutting disk, disposed on the spindle and having cutting surfaces, and a cover, having a bottom opening, configured to removably mount with the bottom opening surrounding the cutting disk. The motor gives the cutting disk a rotational speed sufficient to both (i) remove the husk of a garlic clove which comes in contact therewith, and (ii) mash the garlic clove and fling particles thereof outwardly onto the inside surface of the cover.
In accordance with a more detailed aspect thereof, the invention provides a device for husking and mashing garlic, comprising a base, a motor disposed on the base, a hub connected to and powered by the motor, rotatable about a substantially vertical axis, a substantially planar cutting disk, removably disposable on the hub, having cutting surfaces on a top surface thereof, and configured to rapidly rotate with the hub, and a container, removably mountable surrounding the disk, and extending upwardly therefrom, having an inside surface, and a top opening. The motor causes the disk to rotate at a speed sufficient to both (i) remove the garlic husk, and (ii) mash the garlic clove and fling the particles thereof outwardly onto the inside surface of the cover when a garlic clove is inserted into the top opening and contacts the cutting surfaces of the disk.
In accordance with another more detailed aspect thereof, the invention provides a method of husking and mashing garlic, comprising the steps of: (a) inserting a clove of garlic into a container having an inside surface and surrounding a horizontal cutting disk disposed at the bottom thereof, the cutting disk having cutting surfaces; (b) rapidly rotating the cutting disk, such that the cutting surfaces repeatedly contact the clove of garlic, thereby removing the husk from the clove, and gradually removing small particles of the meat of the clove and centrifugally flinging the particles onto the inside surface of the container, the particles comprising mashed garlic; and (c) removing the container from around the disk so as to gain access to the mashed garlic and the removed husk.
Additional features and advantages of the invention will be apparent from the detailed description which follows, taken in conjunction with the accompanying drawings, which together illustrate, by way of example, features of the invention.

DETAILED DESCRIPTION
For the purposes of promoting an understanding of the principles of the invention, reference will now be made to the exemplary embodiments illustrated in the drawings, and specific language will be used to describe the same. It will nevertheless be understood that no limitation of the scope of the invention is thereby intended. Any alterations and further modifications of the inventive features illustrated herein, and any additional applications of the principles of the invention as illustrated herein, which would occur to one skilled in the relevant art and having possession of this disclosure, are to be considered within the scope of the invention.
Viewing
FIG. 1
, the garlic processor
10
generally comprises a base
12
, a motor
14
, a horizontal rotating cutting disk or rotor
16
, and a container or cover
18
, which is open on the bottom, and removably fits over the disk. The motor is preferably covered by a housing
15
, which underlies the disk
16
, and to which the removable cover
18
attaches.
The cutting disk
16
is removably mounted upon a shaft or spindle
17
, which is driven by the motor
14
. This configuration allows the cutting disk to be removed for easy cleaning. It will be apparent that the mechanism which removably connects the cutting disk to the spindle may be configured in a variety of ways. For example, in one embodiment, shown in
FIG. 5
, the cutting disk
16
is provided with a central collar
60
, which includes a flange
62
that is soldered, brazed, riveted, or otherwise securely fastened into the center of the disk. A device known as a “tee nut” may be used for the collar as depicted.
The central opening
64
of the collar
60
includes spiral threads
66
, which are configured to screw onto mating spiral threads
68
formed on the top
70
of the spindle
17
. The top of the spindle also includes a shoulder
72
, against which the collar
60
abuts when completely screwed on. Using the tee nut collar
60
as shown, the disk
16
may be securely fastened to the spindle with only about one and a half or two turns of the threads. This allows easy attachment or removal of the disk as desired. The threads on the spindle and the collar preferably have an orientation such that rotation of the spindle tends to tighten, not loosen the threads.
The cutting disk includes a plurality of cutting surfaces
22
which are configured to grab and cut the garlic clove when the disk is rapidly rotating, to both (i) remove the husk of a garlic clove which comes in contact with the disk, and (ii) mash the garlic clove and fling particles thereof outwardly onto the inside surface of the cover. These cutting surfaces may take one of many configurations. For example, the cutting surfaces may comprise upwardly protruding rounded punctures
40
, as depicted in FIG.
4
A. These rounded punctures are similar to those of a fine cheese grater, comprising a hole
42
having upwardly protruding sharp edges
44
therearound.
Alternatively, as shown in
FIG. 4B
, the cutting surfaces
22
may comprise a plurality of directionally oriented grating holes
46
. These structures include a hole
48
with a raised cutting edge
50
and sloping rearward portion
52
, similar to a coarse cheese grater. The directionally oriented grating holes
46
are all oriented such that the raised cutting edges face in the direction of rotation (indicated by arrow
41
) of the disk. With this configuration, upon contact with the garlic clove, the blades each grab and cut off a small portion of the garlic clove, whether the husk or the meat, simultaneously propelling the clove upward and forward, and flinging the small portion of garlic tangentially outward due to the rotation of the disk.
As yet another alternative, the cutting surfaces
22
may comprise upwardly protruding planar blades
54
, shown in FIG.
4
C. These blades angularly extend upward, all pointing in the direction of rotation of the disk
16
, and grab and cut the garlic clove in a manner similar to that of the directionally oriented grating holes
46
discussed above. It will be apparent that other configurations of the cutting surfaces
22
may also be used in connection with the present invention.
Because it is used in food preparation, the cutting disk
16
is preferably formed of stainless steel, though other materials such as aluminum may also be used. Referring again to
FIG. 5
, the central collar
60
is likely to be fabricated separately from the planar portion
16
a
of the disk (though integral forming methods may be devised), and then brazed, welded, or otherwise attached around the perimeter of the flange
62
to the planar portion
16
a
of the disk. It will be apparent that, for strength or other reasons, the collar
60
may be formed of a material different from the planar portion
16
a
, so long as the two materials may be adequately attached, and are compatible with each other and with the intended use of the device. The length of the spindle
17
and the location of the shoulder
72
are chosen such that the shoulder supports the disk
16
a small distance H above the top surface of the motor housing (
15
in FIG.
1
). The distance H may be about ¼″, for example.
It will be apparent that a variety of removable mounting configurations may be employed for attaching the cover
18
to the housing
15
. Viewing FIG.
1
and
FIG. 2
, a series of upwardly oriented, L-shaped bars
74
(with outwardly oriented horizontal portions) are disposed in a circle on the top of the housing
15
around the disk
16
. The cover
18
includes a corresponding series of L-shaped slots
76
formed in its bottom rim
26
. To attach the cover
18
to the housing
15
, a user places the bottom rim of the cover over the L-shaped bars
74
, such that the ends of the bars slide into the vertical portion of the L-shaped slots
76
. The user then rotates the cover
18
, so that the ends of the bars
74
slide into the horizontal portion of the slots
76
. The horizontal portion of the slots
76
are slightly tapered, thus producing a wedge effect, which securely holds the cover to the housing.
The removable container or cover
18
includes an opening
19
in its top, and a hatch
20
, connected to the container by a hinge
23
, which allows the opening to be selectively closed. The container may be transparent as shown in the figures, but does not necessarily need to be so. In use, with the container
18
attached to the motor housing
15
and surrounding the disk
16
, one or more garlic cloves are inserted into the container through the opening
19
, and dropped onto the disk. The cover
18
surrounds the disk, with a relatively small clearance therearound, so that the disk may freely rotate, but such that there is not a large gap at the outer edge of the disk into which particles of garlic may fall without being processed. It will be apparent that before the motor
14
is actuated, the hatch
20
is preferably closed for safety reasons, and to contain the garlic husk and meat.
After inserting one or more garlic cloves through the opening
19
, with the hatch
20
closed, the user turns on the motor
14
using power switch
11
, which causes the disk
16
to spin at a high speed. The inventor has found that for a disk having a diameter of about 3¼″, a rotational speed of about 2500 rpm can be effectively used. If the speed is too high, the garlic husk may tend to fly around too much. Alternatively, a speed that is too slow may not quickly or effectively husk and mash the garlic. It will be apparent that the appropriate rotational speed of the disk may vary with different diameter disks, and the invention may be embodied in a variety of different sizes and configurations.
The motor
14
may be a variable speed motor, having a speed control dial
13
for allowing adjustment of the motor speed. An adjustable speed motor may be particularly useful, for example, where cutting disks of various sizes are provided for use with the same motor unit. Power for the motor is provided through power cord
21
, which is configured to insert into a conventional 110 v AC electrical outlet. It will be apparent that the motor
14
may run directly on AC, or may be a DC motor, with a transformer (not shown) in the housing
15
to convert the inpout power. As yet another alternative, the device may utilize a DC motor and be configured to be battery operated.
As the disk
16
spins, it both (i) grabs and removes the husk of the garlic clove, and (ii) gradually grinds the meat of the garlic from the clove and flings it outwardly onto the inside surface of the container
18
. Given the relatively light weight and dry surface of the husk, it tends to be propelled upward in relatively large chunks toward the hatch
20
, apparently due to the centrifugal motion imparted to it by the disk, and perhaps also due to the air vortex created by the rotation of the disk. At the same time, the cutting surfaces cut small particles off of the clove, and fling these particles outwardly onto the inside surface of the cover or container. This process advantageously removes the husk from the clove, and mashes the meat of the garlic.
After a sufficient time, the user may stop the motor
14
and remove the container
18
. After removal, with the container inverted from its original position as shown in
FIG. 2
, the meat of the garlic clove will be mashed and stuck to the inside of the container in a ring
24
near the container rim
26
, allowing the user to easily remove it with a spoon, knife, or other utensil. The husk
28
will tend to be loose and disposed toward the hatch
20
. After removal of the garlic, the husk may be easily dumped from the container, and the disconnected container can be easily cleaned.
Shown in
FIG. 3
is an alternative embodiment of a garlic processor device
10
a
which includes a garlic bulb splitter
30
integrally connected to the processor. The bulb splitter
30
comprises a blunt arrow-shaped wedge
32
, which is mounted on the working end of a rod
39
slidably disposed on a frame
34
above an extended portion
12
a
of the base
12
. This device allows a user to place a bulb of garlic
36
on the base, with the core of the bulb oriented substantially vertically and centered below the wedge, and push down on the handle end
38
of the rod
39
to force the wedge
32
into the bulb
36
to break it into individual cloves. The splitter rod and wedge may be upwardly biased by a spring
40
for convenience.
It will be apparent that a garlic bulb splitter could also be configured in other ways not shown in the figures. For example, a wedge, similar to wedge
32
, could be disposed on the end of a rod in a manner similar to an axe head. An opposite end of the rod could be pivotally connected to the base, such that when the rod is pivoted, the wedge rotates toward a striking position on the base. The user would place the garlic clove on the base below the striking position of the wedge, and pivotally drive the rod and wedge downward into the bulb to split it into individual cloves.
The invention thus provides a convenient appliance for processing garlic, having a spinning processing disk which both (a) separates the husk from the clove, and (b) mashes the garlic. Moreover, the invention comprises a food processing device in which the container
18
for holding the food is open on the bottom, and is inverted to retrieve the processed food.
It is to be understood that the above-described arrangements are only illustrative of the application of the principles of the present invention. Numerous modifications and alternative arrangements may be devised by those skilled in the art without departing from the spirit and scope of the present invention and the appended claims are intended to cover such modifications and arrangements. Thus, while the present invention has been shown in the drawings and fully described above with particularity and detail in connection with what is presently deemed to be the most practical and preferred embodiment(s) of the invention, it will be apparent to those of ordinary skill in the art that numerous modifications, including, but not limited to, variations in size, materials, shape, form, function and manner of operation, assembly and use may be made, without departing from the principles and concepts of the invention as set forth in the claims.
