Patent Law Article 30, Paragraph 2 applies Exhibition name: “HCJ2022 Kitchen Equipment Exhibition” Date: February 15, 2020 to February 18, 2020

The present invention relates to a conveyor device for a fryer, and more specifically to a conveyor device for a fryer that has a cooking tank with a water layer formed at the bottom and an oil layer formed at the top.

A known example of a fryer equipped with a cooking tank in which a layer of water is formed at the bottom and a layer of oil is the fryer disclosed in JP 2014-226428 A (Patent No. 6164933 A) (see Patent Documents 1 and 2).

This fryer is a two-layer fryer that performs the frying process in a cooking tank containing a water layer and an oil layer, and is designed to capture fried food debris that is generated during cooking as it floats in the water and oil layers and discharge it outside the cooking tank.

On the other hand, a known fryer conveyor device is the fryer transport device disclosed in Japanese Patent Application Laid-Open No. 2017-217166 (see Patent Document 3).

The fryer's conveying device has a bar conveyor that is located in an oil tank containing oil and drives in a circular motion, and multiple conveying plates that are rotatably connected to the shaft of the bar conveyor and transport food ingredients.

JP 2014-226428 A Patent No. 6164933 Japanese Patent Application Laid-Open No. 2017-217166

In the two-layer fryer disclosed in Patent Document 1, when a conveying device with conveying plates is installed, multiple conveying plates pass through the boundary surface between the water layer and the oil layer in an upright position, which causes the boundary surface to be agitated and the water and high-temperature oil to mix, which is a problem.

Therefore, even when a conveying device with a conveying plate is installed in a conventional two-layer fryer, there is a problem that must be solved: how to create a system that prevents the water and high-temperature oil from mixing when passing through the boundary surface between the water layer and the oil layer without stirring the boundary surface.

The gist of the present invention for solving the problems of the conventional example is as follows:
The conveyor device ( 11) for a fryer is located in a cooking tank (34) in which a layer of water is formed at the bottom and a layer of oil is formed on top of the water layer, and the conveyor device (11) for a fryer is provided with at least a conveyor body (17 ) having a pair of chains (16 ) that are driven in a circular manner across a first rotating shaft (13) on the side of a food inlet ( 12) and a second rotating shaft (15) on the side of a food outlet ( 14 ), a support shaft ( 18 ) that is stretched between the pair of chains ( 16), a partition plate (19 ) for moving food that is rotatably provided on the support shaft (18 ), a conveyor lower frame (20 ) that is provided on the lower side of the conveyor body (17) , and an apron plate (21 ) that is located above the conveyor lower frame ( 20 ) and that comes into contact with a bent portion (19a) of the partition plate (19). The conveyor lower frame (20) is provided at a position where the partition plate (19) comes into contact. The partition plate 19 is configured to move in a tilted state due to this contact, and the partition plate 19 consists of a main body portion 19b formed in a L-shape and a bent portion 19a formed continuously by bending from the end of the main body portion 19b via the support shaft 18, and the conveyor lower frames 20 are provided on the lower side and both sides of the conveyor main body 17, and the width dimension B of the partition plate 19 is longer than the gap dimension D between the conveyor lower frames 20, so that the end portions 19c of the main body portion 19b of the partition plate 19 come into contact with the conveyor lower frames 20 on both sides, and the contact of the end portions 19c causes the tip side of the main body portion 19b of the partition plate 19 to move in a tilted state upward .

The partition plate 19 , which moves in the tilted state, is released from the tilted state at the contact end of the conveyor lower frame 20 and hangs down, so that the fried food scraps received by the partition plate 19 fall;
The bent portion 19a of the partition plate 19 comes into contact with the apron plate 21 , so that the partition plate 19 moves in an upright state;
It includes:

The fryer conveyor device of the present invention is designed so that the partition plate moves in a tilted position while in contact with the lower conveyor frame. This provides the excellent effect of preventing the water and high-temperature oil from mixing when the partition plate passes over the boundary between the water and oil layers in the cooking tank because the partition plate is tilted.

The partition plate, which moves in a tilted state, is released from its tilted state at the end of its contact with the conveyor lower frame and hangs down, allowing the fried debris caught by the partition plate to fall, allowing the debris to be carried above the discharge outlet and drop there. As a result, the amount of fried debris that settles in the cooking tank can be reduced, achieving the excellent effect of improving the efficiency of debris collection.

The folded portion of the partition plate comes into contact with the apron plate, causing the partition plate to move in an upright position. This provides the excellent effect of allowing ingredients inserted through the ingredient inlet to be moved by the upright partition plate, and the fried ingredients to be removed from the ingredient removal opening.

FIG. 2 is a front view of the conveyor device of the fryer according to the present invention. FIG. 2 is a left side view of FIG. 1 . 1 is a plan view of a conveyor device of a fryer according to the present invention. FIG. 1 is a front view showing an outline of a fryer equipped with a conveyor device according to the present invention.

Next, an embodiment of the present invention will be described with reference to the drawings. First, in Figures 1 and 2, the reference numeral 11 denotes a fryer conveyor device. This fryer conveyor device 11 is composed of a conveyor main body 17 having a pair of chains 16 that circulate between a first rotating shaft 13 on the food inlet 12 side and a second rotating shaft 15 on the food outlet 14 side; a support shaft 18 stretched between the pair of chains 16; a partition plate 19 for moving food that is rotatable relative to the support shaft 18; a conveyor lower frame 20 attached to the lower side of the conveyor main body 17; and an apron plate 21 positioned above the conveyor lower frame 20 and with which the bent portion 19a of the partition plate 19 comes into contact.

The fryer conveyor device 11 is installed in a fryer 31 that includes a cooking tank 34 in which a layer of water forms below and a layer of oil forms above it (see Figure 4). As will be described later, this fryer 31 has a mechanism that can capture floating matter, such as fried food debris, that is generated during cooking as it floats in the water and oil layers and discharge it outside the cooking tank 34.

The first rotating shaft 13 and the second rotating shaft 15 are rotated by a driving force of a motor or the like (not shown) being transmitted to the second rotating shaft 15 .
Circular wheels 13a are provided on both ends of the first rotating shaft 13, and gears 13b are formed on the outer periphery of the wheels 13a (see FIG. 1). Similarly, circular wheels 15a are provided on both ends of the second rotating shaft 15, and gears 15b are formed on the outer periphery of the wheels 15a (see FIG. 1).

The pair of chains 16 are provided on both ends of the first rotating shaft 13 and on both ends of the second rotating shaft 15 (see FIG. 2).
In addition, the chain 16 is arranged in a state where it engages with the gear 13b of the first rotating shaft 13, and is also arranged in a state where it engages with the gear 15b of the second rotating shaft 15, so that this chain 16 is driven in a circular motion between the second rotating shaft 15 and the first rotating shaft 13 as the second rotating shaft 15 is rotated.

As described above, the conveyor body 17 comprises a first rotating shaft 13 on the food inlet 12 side, a second rotating shaft 15 on the food outlet 14 side, and a pair of chains 16 that circulate from the first rotating shaft 13 to the second rotating shaft 15.
1 and 3, the food processor has an apron plate 21 consisting of a first apron plate portion 21a located in the horizontal portion and a second apron plate portion 21b formed at an angle from the first apron plate portion 21a. A food outlet chute 22 (see FIG. 4) is provided on the food outlet 14 side.

The support shafts 18 are installed across a pair of chains 16 (see Figure 2) and are installed at multiple locations at predetermined intervals (see Figure 1).

The partition plate 19 shown in FIG. 2 has a width B of, for example, about 295 mm, a required height, and is provided rotatably about the support shaft 18 .
As shown in FIG. 1, the partition plate 19 is made up of a main body portion 19b formed in a V-shape and a bent portion 19a formed continuously by bending the end of the main body portion 19b via the support shaft 18.

As shown in FIG. 2, the conveyor lower frame 20 is provided on both sides of the lower side of the conveyor main body 17 .
As shown in FIG. 1, the conveyor lower frame 20 has a contact starting end 20a with the partition plate 19 near the food material removal opening 14, and is connected to an inclined portion 20b connected to the contact starting end 20a and a flat portion 20c connected to the inclined portion 20b, with the flat portion 20c having a contact terminal end 20d with the partition plate 19 (see FIG. 1).

2 is approximately 41.5 mm. The gap D between the adjacent conveyor lower frames 20 is approximately 270 mm.
As such, while the width dimension B of the partition plate 19 is approximately 295 mm, the gap dimension D between the conveyor lower frames 20 is approximately 270 mm, so that both ends 19c, 19c of the partition plate 19 (main body portion 19b) come into contact with the conveyor lower frame 20, and as shown in Figure 1, the contact of both ends 19c, 19c causes the partition plate 19 to move in a tilted state.

The partition plate 19 configured in this manner comes into contact with the contact starting end 20a of the conveyor lower frame 20 and moves in a tilted state. In other words, by moving in a tilted state, the tilted partition plate 19 does not agitate the boundary surface between the water layer and the oil layer in the cooking tank as it passes over the boundary surface, preventing the water and high-temperature oil from mixing.

The partition plate 19, which moves in a tilted state, is released from its tilted state at the contact end 20b of the conveyor lower frame 20 and hangs down (see Figure 1). In this case, the fried food debris received by the partition plate 19 (main body 19b) falls. This allows the fried food debris received by the partition plate 19 to be carried above the discharge outlet and fall, which reduces the amount of fried food debris that settles in the cooking tank and improves the efficiency of collecting fried food debris.

The partition plate 19, which is in a hanging state, rises as the first rotating shaft 13 rotates (see arrow A1), and the bent portion 19a comes into contact with the apron plate 21 and stands up (see Figure 1).

The apron plate 21 is located above the conveyor lower frame 20 and consists of a flat section 21a that extends from the vicinity of the food inlet 12 toward the food outlet 14, and an inclined section 21b that slopes from the flat section 21a, and is positioned so that it comes into contact with the folded section 19a of the partition plate 19 (see Figures 1 and 2).

When the folded portion 19a of the partition plate 19 of this type comes into contact with the apron plate 21, the partition plate 19 moves in an upright position, and food inserted through the food inlet 12 is moved by the upright partition plate 19, allowing the fried food to be removed from the food outlet 14.

The partition plate 19, which is in an upright position, descends as the second rotating shaft 15 rotates (see arrow A2), and the bent portion 19a comes into contact with the contact starting end 20a of the conveyor lower frame 20, causing it to move again in a tilted position (see Figure 1).

Next, we will provide an overview of a fryer equipped with a conveyor device according to the present invention. Figure 4 is a front view showing the outline of the fryer. The fryer 31 is generally composed of a fryer main body 33 with legs 32 at the bottom, a cooking tank 34 located inside the fryer main body 33, a draft tube 35 that discharges floating matter in the cooking tank 34 to the outside, and a control panel 36 located on the top of the fryer main body 33.

A layer of water forms at the bottom of the cooking tank 34, and an oil layer forms above that. The fryer's conveyor device 11 is located inside the cooking tank 34. The floating matter floating in the oil and water layers is guided and collected in a part of the cooking tank 34, and as the water layer rises due to the supply of water to the cooking tank 34, the guided floating matter is sucked into the draft tube 35, and the sucked floating matter is discharged from the bottom end of the draft tube 35.

The fryer conveyor device 11 configured as described above is configured so that the partition plate 19 moves in a tilted position while in contact with the conveyor lower frame 20. As a result, when the partition plate 19 passes over the boundary between the water layer and the oil layer in the cooking tank, the tilted partition plate 19 does not agitate the boundary. Therefore, the water and high-temperature oil do not mix due to the partition plate 19.
