Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for producing steamed products (for example, kamaboko, sausage, steamed bun, etc.) requiring steaming treatment, and steaming the raw materials before transporting them in a steaming room. The present invention relates to a food steaming apparatus which is designed to be moved.

[0002]

2. Description of the Related Art In this type of food steaming apparatus, a transport conveyor for placing and transporting raw materials before steaming (hereinafter referred to as "raw material") is disposed in a steaming chamber. A flat belt without air permeability (for example, a flat steel belt or a flat Teflon belt) has been used.

[0003]

However, when a flat belt is used as a belt for a conveyor as in a conventional food steaming apparatus, since the flat belt has no air permeability, steam accumulates on the belt. The raw material swells due to the retained steam, and water droplets and air are accumulated between the raw material and the belt, so that an expanded burrow is formed on the bottom surface of the raw material, thereby deteriorating the quality of the manufactured steamed product. There was a problem that it would.

Further, it is desirable to arrange the conveyors in a plurality of upper and lower stages so as to be advantageous in terms of shortening the machine length, arrangement space, running cost, and the like. However, when the conveyors are arranged in a plurality of upper and lower stages, when the raw materials are transferred from the upper stage to the lower stage, deformation or breakage occurs due to the impact caused by the falling of the raw materials, thereby causing a problem that defective products are generated.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and it is intended to prevent steam from staying on a belt, to eliminate swelling of the material caused by the staying steam, and to prevent the material from swelling on the bottom surface of the material. The occurrence of burrows that occur can be eliminated, and furthermore, the conveyors are arranged in upper and lower stages to obtain advantages in terms of shortening machine length, layout space, running cost, etc., while moving from the upper side to the lower side. It is an object of the present invention to provide a food steaming apparatus capable of smoothly delivering and receiving raw materials and suppressing generation of defective products due to deformation and breakage.

[0006]

In order to solve the above problems, a food steaming apparatus according to the present invention (Claim 1) has a transport conveyor for placing and transporting raw materials before steaming in a plurality of upper and lower stages in a steaming chamber. In the food steaming apparatus arranged, each conveyor is formed by a mesh belt being wrapped around a starting roller and an ending roller, and is terminated on an upper conveyor between vertically adjacent conveyors. An adsorber for adsorbing the raw material before steaming onto the mesh belt through an air inlet formed in the side roller was provided.

In this food steaming apparatus, since the belt is formed by a mesh belt, steam can pass through the mesh belt. Therefore, the stagnation of the steam due to the steam being blocked by the belt is eliminated, and the swelling of the raw material due to the stagnant steam and the occurrence of burrows generated on the bottom surface of the raw material can be prevented.

[0008] Further, since the conveyors are arranged in a plurality of upper and lower stages, advantages can be obtained in terms of shortening the machine length, arrangement space, running cost and the like. And
When the raw material is transferred from the upper side to the lower side, the raw material conveyed by the conveyor is adsorbed on the mesh belt through the suction port formed in the end roller by the suction device in the circulating section at the end, and the end in that state. The transition is made to the lower transition section while the reciprocating section is being shifted. Then, after the suction by the suction device is released, it is peeled off from the mesh belt and transferred to the lower side. In this way, when transferring the raw material from the upper stage to the lower stage, the raw material is adsorbed on the mesh belt at the terminal circulating portion and is transferred, so that the raw material delivery is smooth, and defective products due to deformation or damage are removed. Occurrence can be suppressed.

Further, in the present invention, a stripping device for stripping the raw material before steam adsorbed on the mesh belt by the suction device by means of gas discharged from a gas discharge port disposed on the back side of the mesh belt at a lower transition portion near the end roller. Is provided (claim 2). As described above, when the peeling device is provided, the raw material adsorbed on the mesh belt can be reliably peeled off at a fixed position by air.

The suction device 7 is provided on each of the end rollers 32 of the intermediate conveyance conveyor 3 and on the end rollers 42 of the intermediate conveyance conveyor 4 between the middle conveyance conveyor 4 and the lower conveyance conveyor 5. In the upper conveyor 3 and the middle conveyor 4 provided with the suction device 7, peeling devices 8, 8 are respectively provided on the back side of the belts 30, 40 at the lower transition portion near the end rollers 32, 42. ing.

FIG. 3 shows a suction device 7 and a peeling device 8 provided on the upper conveyor 3. The adsorption device 7
An intake space 70 is formed inside the trailing end roller 32, and a large number of intake ports 71 are formed on the outer peripheral surface thereof. An intake hose 72 extending from the intake side of the blower 9 is connected via a rotary joint (not shown). Thus, the structure is connected to the intake space 70. In the peeling device 8, an exhalation tube 80 is provided on the back side of the belt 30 at a lower transition portion near the end-side roller 32, and an exhalation port 81 is formed in the exhalation tube 80 so as to face the belt 30. An air supply hose 82 extending from the exhaust side of the blower 9 is connected to the exhaust pipe 80. Note that the suction device 7 and the peeling device 8 provided on the middle conveyor 4 have the same structure.

Next, the operation of the food steaming apparatus will be described. This food steaming device is a device for producing steamed products (for example, kamaboko, sausage, bun, etc.) requiring steaming treatment, and feeds the raw material A before steaming (hereinafter referred to as “raw material”) on conveyors 3, 4. , 5 are steamed while being conveyed in the steaming room. In this case, first, when the raw material A is placed on the belt 30 at the start end side of the upper conveyor 3, the raw material is transported in the direction of the arrow by the transfer of the belt 30, and enters the steaming chamber 10 through the carry-in port 11. Then, it is transferred to the middle-stage conveyor 4 after moving to the end circulation section. The raw material A is continuously conveyed in the direction of the arrow by the middle conveyance conveyor 4, again transferred to the lower conveyance conveyor 5 after shifting the terminal circulating section, and further conveyed by the lower conveyance conveyor 5 in the direction of the arrow, After coming out of the steaming chamber 10 through 12, it is withdrawn at the end. As described above, the raw material A is steamed by the steam from the steam pipes 15 and 15 in the course of being transported in the steaming chamber 10 by the transport conveyors 3, 4 and 5.

At this time, since the belts 30, 40, 50 of the respective conveyors 3, 4, 5 are formed of mesh belts, steam can pass through the mesh belts. Therefore, since the flow of the steam is not interrupted by the belts 30, 40, and 50, the stagnation of the steam is eliminated and the swelling of the raw material A due to the stagnant steam and the occurrence of burrows generated on the bottom surface of the raw material A can be prevented. .

As described above, the belts 30, 40, 5
Since the blower fan 2 is disposed in the steaming chamber 10 after forming the mesh 0 with a mesh belt, the steam flows through the entire steaming chamber 10 by the forced blowing by the blower fan 2, The temperature boundary layer generated around the raw material A can be forcibly blown off. Therefore, heat transfer to the raw material A is promoted, and the time required for raising the temperature of the raw material A can be reduced. According to the experimental results by the present applicant, when the blower fan 2 was provided, the temperature rise time was reduced to 1/3 (specifically, 15 minutes took 5 minutes instead of not provided). . Further, since the steam flows by the blower fan 2, the steam hardly directly touches the raw material A,
For this reason, a steamed product of good quality without swelling or browning can be produced. Also, since the steam circulates, the raw material A
Water droplets are less likely to be generated on the surface, and the surface solidifies quickly and becomes dry. Therefore, the evaporation of water from the surface of the raw material A is small, and the movement of water is small, so that a stable steamed product with a small basis weight expansion and loss can be manufactured. Even when dropped, deformation and breakage are reduced due to solidification of the raw material, and occurrence of defective products can be suppressed. Furthermore, blower fan 2
Are arranged with the air blowing direction reversed, so that the steam flows evenly throughout the steaming chamber 10. Therefore, temperature unevenness is eliminated, and heat can be uniformly transferred to each raw material A. Therefore, there is no unevenness in the steaming of each raw material A, and the quality of the steamed product can be stabilized.

Further, since the conveyors 3, 4, and 5 are arranged in a plurality of upper and lower stages, the machine length can be shortened and the arrangement space can be reduced.
Advantages can be obtained in terms of running costs and the like. Then, for example, upon delivery of the raw material A from the upper side (for example, the upper conveyor 3) to the lower side (for example, the middle conveyor 4), the raw material A conveyed by the upper conveyor 3 The belt 3 is passed through the suction port 71 formed in the end roller 32 by the suction device 7.
At this time, the state is shifted to the lower transition part while transitioning at the terminal traveling part in this state. Then, after the suction by the suction device 7 is released, the sheet is separated from the belt 30 and transferred to the middle conveyor 4. At the time of this peeling, the raw material A adsorbed on the belt can be surely peeled off at a fixed position by air, since the raw material A adsorbed on the belt can be peeled off by the air discharged from the air discharge port 81 provided in the peeling device 8. As described above, when the raw material A is transferred from the upper stage to the lower stage, the raw material A is adsorbed on the belt 30 at the terminal circulating portion, and the transfer is performed. It becomes smooth, and the occurrence of defective products due to deformation or breakage can be suppressed.

The embodiments of the present invention have been described above.
The specific configuration of the present invention is not limited to this embodiment. For example, the transport conveyor does not necessarily need to be provided in three stages (multi-stage), but may be in two or more stages. Although it is not always necessary to provide a blower fan, it is preferable to provide a plurality of blower fans with reversed blow directions as shown in the embodiment in order to stabilize the quality of the steamed product. The material and air permeability of the conveyor belt can also be determined appropriately according to the type of steamed product, the transport amount, the transport speed, and other conditions. In addition, although a common blower is used for the suction device and the separation device, it is natural that independent suction means (for example, a suction pump or the like) and air supply means (for example, a gas blower) can be used independently. Further, it is possible to arbitrarily add a cleaning device for cleaning the belt of the conveyor.

[0022]

As described above, in the food steaming apparatus according to the present invention (claim 1), since the belt of the conveyor is formed of a mesh belt, there is no stagnation of steam, and the stagnant steam is eliminated. Swelling of the raw material and the occurrence of burrows generated on the bottom surface of the raw material can be prevented. In addition, an adsorber is provided to transfer the raw material from the upper stage to the lower stage by adsorbing the raw material to the mesh belt at the terminal circulating section, so that the raw material can be smoothly delivered, deformed or damaged. This can suppress the occurrence of defective products.

Further, when a peeling device is provided (claim 2), the raw material adsorbed on the mesh belt can be peeled off reliably and at a fixed position by air.
