Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a food fryer device.

[0002]

2. Description of the Related Art In a conventional food fryer, oil is poured into an oil tank of a certain depth, the bottom of the tank is heated, and a conveying means such as a wire net is provided at a certain height in the tank. In general, a configuration in which the input is performed is often used.

[0003]

In order to obtain high-quality products with the fryer apparatus, a low-temperature tank and a high-temperature tank are divided. In this case, a large amount of oil is charged in the low-temperature tank. The frying material is transported in a state where the oil temperature in the tank is set at a relatively low temperature of about 120 to 140 ° C., and the oil temperature is sufficiently permeated to the core of the frying material. In general, there is a problem that the tank is relatively long, such as about 6 m in total length, and the installation space becomes large. The present invention not only solves the above-mentioned problems, but also contributes to the improvement of productivity by promptly uniforming the oil temperature and saving space with respect to a general food fryer device. It is assumed that.

[0004]

The present invention is characterized in that a stirring means for stirring oil in a tank is provided in an endless conveyor for conveying fried material immersed in an oil tank. At this time,
The stirring means is arranged at appropriate intervals at a plurality of positions in the length direction in the endless conveyor for conveyance, and as this stirring means, a paddle, an eccentric plate, a screw blade is rotated, Alternatively, the agitation is performed by ejecting the oil in the tank by circulating the oil in the tank by driving a pump from a pipe having a large number of through holes.

[0005]

FIG. 1 is a longitudinal sectional view schematically showing the entire device of the present invention, FIG. 2 is a sectional view taken along line XX of FIG.
FIG. 3 is a sectional view taken along line YY of FIG. Reference numeral 1 denotes a base of the apparatus, which supports an oil tank 2. Here, the front (advancing side) bottom surface of the oil tank 2 is formed as a gentle upward slope, and the endless conveyor 3 for transporting the fried material is provided on the bottom side along the longitudinal direction in the tank, and on the top side. Is provided with an endless conveyor 4 for holding products.

[0006] The endless conveyor 3 and the endless conveyor 4 for conveying the fried material are attached to left and right side plates 5a and 5b which form a frame body in an oil tank in the width direction. The side plates 5a and 5b are supported on an inverted U-shaped pedestal H standing upright with the base 1 of the apparatus therebetween so as to be able to move up and down by suspending means such as a wire or a winch (not shown).

Reference numerals 6a and 6b denote locking plates protruding outward from the left and right side plates 5a and 5b.
The side plates 5a, 5b supporting the first and fourth lugs 4 are engaged with the left and right overhangs 2a, 2b of the oil tank 2 so as to be placed at a fixed depth position.

According to the present invention, the stirring means is provided in the endless conveyor 3 in the present invention. In the first embodiment, the paddle 7 is provided. That is, as specifically seen in the sectional views of FIGS.
The shaft 8 is rotatably mounted by using the shaft b as a bearing, and a paddle 7 having a plurality of (four in the illustrated example) blades is radially mounted on a central portion of the shaft 8. The paddle 7 is automatically rotated when the tooth tips of the sprockets 7a and 7b attached to both ends are brought into engagement with the lower net k of the endless conveyor 3 for traveling and traveling, whereby the paddle 7 is rotated. Then, the oil in the tank is continuously stirred.

FIG. 4 shows an example in which the eccentric plate 9 is used as the stirring means. In this example, the arms 10a and 10b are moved to the eccentric positions on the inner surfaces of the opposing sprockets 7a and 7b by the pins 11a and 11a.
11b, it is rotatably mounted, and a plate 9 is mounted between the arms 10a, 10b. In the same manner as in the previous example, the sprockets 8a and 8b automatically rotate by being brought into contact with the lower net k of the endless conveyor 3 for traveling and moving, so that the plate 9 is out of stirring of the oil in the tank. Then, it comes into contact with the net conveyor 3 so as to vibrate it.

FIG. 5 shows an example in which the screw blade 12 is used as the stirring means. In each of the above-mentioned examples, the net surface of the endless conveyor 3 for transporting and moving the drive source and the sprocket 8 are used.
In contrast to the case in which the steps a and 8b are performed automatically by the engagement and contact, in the present embodiment, the step is performed using a separately provided small motor 13. (However, in this embodiment, similarly to the above example, the sprocket which is engaged and rotated with the transfer net 3 can automatically rotate the screw blade 12 by employing a worm or a gear mechanism.) Reference numeral 14 denotes a bridge plate horizontally disposed from the side plates 5a and 5b to the inside of the endless conveyor 3 for transport. A bearing 15 is mounted on a lower surface of the plate 14, and a screw blade 12 is mounted with a sprocket 16 on a shaft portion 13 thereof. Tonashi, chain belt 1
The sprocket 19 attached to the lower end thereof is rotated by the rotation of a rotation shaft 18 driven via a speed reducer from a small motor 13 fixed on the locking plate 6a through the rotation plate 7.

FIG. 6 shows still another stirring means. In this embodiment, pump means is used to stir the oil in the tank. That is, reference numeral 20 denotes a circulating pump disposed outside the tank, and a suction pipe 21 for taking in the oil in the oil tank 2 is attached to the suction side of the pump 20, while the discharge side has a length within an appropriate range. The discharge pipe 23 is connected via a flexible pipe 22 which can be expanded and contracted. The distal end of the discharge pipe 23 is inserted into the endless conveyor 3 for conveying the fried material from the side plate 5b into the endless conveyor 3 having a large number of through-holes s formed in the outer peripheral surface of the discharge pipe 23 in a predetermined length. It is configured to be provided. In the present example, the use of a flexible tube 22 causes the endless conveyors 3 and 4 to be raised upward in the oil tank 2 as needed, that is, together with the side plates 5a, 5b supporting them. This is to make it possible to follow without any trouble.

The stirring means using the paddle, the eccentric plate, the screw blade, the pump, or the like having the above-mentioned structure is provided in the oil tank 2 singly or at appropriate intervals, for example, at a plurality of intervals of about 50 cm. In the arrangement, the arrangement is not limited to the same one but may be appropriately combined and arranged.

In the operation and use of the apparatus constructed as described above in the present invention, the oil in the oil tank 2 is automatically or forcibly stirred from the bottom of the tank, so that the temperature of the hot water in the tank can be made uniform for a short time. The thickness of the tempura (mm) indicates whether the stirring and the center temperature of the fried material (tempura) increase with time.
The results of the tests in comparison with are shown in the following table.

[0014]

[Table 1]

From Table 1, it can be seen that there is a time difference of 1 minute between the case where the stirring is performed and the case where the stirring is not performed and the temperature in the core reaches 60 ° C. when the thickness of the tempura is 15 mm. . This indicates that the time of stirring is reduced to about 1/3 of the time of stirring without stirring.

[0016]

The present invention is constructed as described above, and the temperature of the fried material can be raised at least 30% or more as quickly as that of the conventional apparatus. This phenomenon becomes more prominent as the thickness of the fried material decreases. The above-mentioned facts not only improve the productivity, but also make it possible to reduce the size of the fryer device and economical use of oil, and to reduce the overall cost.
