[Detailed description of the invention]

[0001]

This invention relates to a continuous baking apparatus which supplies a material having fluidity to a continuously moving baking section and continuously bake eggs, hot cakes, cookies, and the like. The present invention relates to a cleaning device for removing adhered substances.

[0002]

2. Description of the Related Art A continuous baking apparatus of this type includes a drum system for supplying a material to the surface of a rotating baking drum, a belt conveyor system for supplying a material onto a thin steel belt wound endlessly, and a large number of baking plates. There are various systems such as a crawler system in which a baking section is formed by connecting endlessly via a transport chain.However, in a drum system, only a very thin sheet-shaped food can be manufactured with a short baking distance. Thin steel belts are locally distorted by cooling, making it impossible to obtain sheet-like foods of uniform thickness. In the crawler method, the transport chain stretches due to heating, creating gaps between the sintering plates and leaking material. There is.

[0003] For this reason, the present applicant has already filed an application for a continuous firing apparatus capable of solving such a drawback (Japanese Patent Application No. 2-254599). In this continuous baking apparatus, independent baking plates are supplied one by one to a baking section, and the baking section is pushed from behind to form a moving continuous baking section in a plate shape. After applying a non-stick oil to the baking section, a fluid material such as egg solution is supplied, and baking food in a sheet form is continuously produced by heating and baking.

[0004]

However, in the case of the crawler system or the independent pushing system using a plurality of firing plates as described above, scorched matter is generated on the upper surface of the firing plate or between the firing plates. Cause the product to get mixed in the food department,
Oil oxides and burnt powder clogging the gaps between the fired plates may cause the gaps to be further expanded. Further, in the case of the independent pushing method, the gap between the respective firing plates can be reduced to zero by using a driving device including a rack pin and a pinion, but the dimensional error of the firing plates and the difference in thermal expansion and contraction can be reduced. If a slight gap is generated due to the above, oil or a liquid component of the material enters through the gap, further flows to the back side of the fired plate, and is heated to form a polymer. This polymer is not easy to remove if left alone, and if used continuously as it is, the polymer may cause deterioration in heating efficiency. Therefore, in the case of continuous operation, after stopping for a few hours, the operation was stopped once, and the burnt material on both abutting surfaces and the upper and lower surfaces of each fired plate was removed. There is a problem that the property is reduced.

The present invention has been made in order to solve the above-mentioned conventional problems. An object of the present invention is to form a plate-shaped sintering section which is continuous in the transport direction by arranging a plurality of independent sintering plates. The present invention provides a cleaning apparatus for a continuous baking apparatus which can easily and surely remove deposits attached to the abutting end surfaces and upper and lower surfaces of each baking plate, thereby enabling continuous operation. .

[0006]

SUMMARY OF THE INVENTION The cleaning device of the present invention comprises:
In a continuous baking apparatus for arranging a plurality of independent baking plates to form a plate-like baking section that is continuous in the transport direction and supplying materials onto these baking plates to continuously manufacture baking foods, The scraper blade that moves along the contact end face scrapes off the deposits on the contact end face, and the brushes and spray water that contact the upper and lower surfaces of each firing plate remove the deposits on the upper and lower surfaces. The brush mechanism is provided.

[0007]

The scraper blade scrapes off the deposits on the contact end surfaces of the respective firing plates. The abutting end face of each fired plate is the most important face, and the oxide of vegetable oil having small particles adheres a lot, which is difficult to remove by brushing, but can be easily and reliably removed by a scraper blade. Further, in the case of a roll brush, the brush is worn at a corner portion of the baking plate abutting surface, but with a scraper blade, there is no concern. Deposits on the upper and lower surfaces of each firing plate are removed by the roll brush. The upper surface of the baked plate is mainly for scorching food, and the lower surface is a very small amount of vegetable oil deposits, which can be easily and reliably removed with a roll brush. By spraying spray water during or before the removal with the roll brush, the burnt matter is washed or the burnt matter is swollen, and the removal effect by the roll brush can be enhanced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to an embodiment shown in the drawings. This is an example in which the present invention is applied to a continuous baking apparatus for producing eggs and hot cakes. FIG. 5 is a schematic side view of a continuous firing device to which the cleaning device according to the present invention is applied. The continuous firing device 10 is provided with a large number of trough-attached firing plates 1 and an upstream side to a downstream side. Elevator 11 for baking plate supply, transfer pusher 12, oiling device 13, material supply device 14, roller conveyor 15, driving device 16 for pushing, slide rail 17, heater 18, brake device 19, for collecting baking plate It comprises an elevator 20 and the like.

As shown in FIG. 1, the baking plate 1 with a trough has a rectangular shape in a plan view, and a trough 1b is formed at a central portion by integrally projecting weirs 1a on both short sides. As shown in FIG. 5, both short sides of the fired plate 1 are placed on a pair of slide rails 17 and a driving device 16 is provided.
By pushing the baking plate 1 on the most upstream side of the slide rail 17, the front end face and the rear end face on the adjacent long sides are arranged in contact with each other, and the trough-shaped baking section 21 continuous on the slide rail 17 is arranged. To form The driving device 16 includes, for example, a rack pin 2 projecting from a short side end face of the firing plate 1, a pinion 3 meshed with the rack pin 2, and
An electric motor 4 for rotating and driving the pinion 3 is provided.
, And the whole of the fired plate downstream therefrom can be indirectly pushed.

The firing plate 1 is supplied from a supply elevator 11 via a roller conveyor 15. The fired plate 1 from the supply elevator 11 is transferred onto the roller conveyor 15 by the transfer pusher 12. The roller conveyor 15 rotates and drives the roller group in synchronization with the chain drive mechanism 22.
The firing plate 1 is transferred onto the slide rail 17. This transfer speed is synchronized with the pushing speed of the pinion 3 or set at a speed slightly higher than the pushing speed so that no gap is formed between the front firing plate and the rear firing plate at the pinion 3 position.

The oiling device 13 and the material supply device 14 are arranged on the entrance side of the slide rail 17, that is, above the position of the drive device 16, and can supply the material after laying oil for preventing burning on the firing plate 1. It has been like that. Heater 18
Extends below the slide rail 17 so that the material on the firing unit 21 that moves at a constant speed can be fired.
Baking plate 1 extruded from the exit side of slide rail 17
Is received by the support claw 20a of the collection elevator 20, and is returned by a return conveyor equipped with a pusher or a baking unit 21.
Is returned to the supply elevator 11 by a pushing method using a slide rail and a driving device. In the return step, the firing plate 1 is preheated as necessary.

Each fired plate 1 to be fed does not separate from the contact surface between the fired plates due to frictional resistance with the slide rail 17, but it is preferable that the brake device 19 applies the resistance. The brake device 19 includes a pressing roller 19a and a coil spring 19b, and is configured to lightly press the upper surface of the weir 1a of the firing plate 1 with the pressing roller 19a. The fired plate 1 is, for example, 130 to 1
Heated to 80 ° C., the temperature distribution of the fired plate is almost uniform and the thermal expansion is constant. However, when a material at normal temperature is supplied to the center of the fired plate 1 in the left-right direction, the temperature of this center portion The descent is greater than at both ends, and the difference in thermal expansion creates a gap at the center. In this case, curved convex portions corresponding to the contraction amount at the central portion are formed in advance at the front end and the rear end of the fired plate 1 so that no gap is generated at the time of material supply.

In such a configuration, as shown in FIG. 5, for example, a supply elevator 11 and a roller conveyor 15 are provided.
In between, the scraper mechanism 5 for removing the deposits on the contact surface of the firing plate 1 and the brush mechanism 6 for removing the deposits on the upper and lower surfaces of the firing plate 1 are incorporated in the roller conveyor 15. As shown in FIGS. 1A, 2 and 3, the scraper mechanism 5 mainly includes a scraper blade 30, a slider 31, a guide rail 32, a drive cylinder 33, and a table 3
4. It is composed of an elevator 35. Scraper blade 3
Numeral 0 is a blade for scraping off deposits (mainly oxides of vegetable oil) attached to the contact end face 1c before and after the firing movement direction of each firing plate 1. The oxide steel is made of spring steel and hardly removes oxides that cannot be removed by brushing. Provide sufficient strength to remove. The shape is, for example, a plate having an arcuate cross section, the base portion is fixed to the slider 31, and a sharp edge that contacts the contact surface 1c is formed at the distal end portion.

The guide rail 32 is disposed so as to sandwich the mounting table 34 so as to be orthogonal to the firing movement direction, and both ends are fixed on an elevating table 35, and the slider 31 is movably guided and supported. The slider 31 is pinned to the tip of a piston rod of a drive cylinder 33 fixed on the lift 35, and can be reciprocated by the drive cylinder 33. Guide rail 3
The strokes of the drive cylinder 2 and the drive cylinder 33 are set so that at least the attached matter on the contact surface 1c of the trough 1b can be removed. The elevator 35 is disposed between the transfer pusher 12 and the roller conveyor 15, and the supply elevator 11 is arranged beside the elevator 35. The elevator 35
Is guided and supported by a guide / guide rod 38 and is moved up and down by a lifting cylinder 39.

The table 34 has a roller conveyor 1 on its upper surface.
5 is fixed above the elevating table 35 so as to coincide with the upper surface of the elevating platform 5 and extends in a direction orthogonal to the firing moving direction, so that the firing plate 1 from the supply elevator 11 can be received. Further, a stopper 34a is provided on the mounting table 34, and is positioned so as to be continuous with the baking plate 1 on the roller conveyor 15. Supporting claws 11a of the supply elevator 11
The upper firing plate 1 is placed on a table 34 by a pushing pusher 36.
Transfer to the top. When the scraping operation is completed, the lift 35
Is lowered and transferred to the roller conveyor 15 by the transfer pusher 12. At this time, a space is provided between the baking plate 1 on the table 34 and the roller conveyor 15,
Here, an auxiliary roller group 37 is provided. This auxiliary roller group 3
7 is attached to the elevator 35 so that the roller 37a is at the same level as the roller 15a of the roller conveyor 15 at the lower limit of the elevator 35.

A spray header for spraying water or hot water toward the contact surface 1c of the firing plate 1 is provided in parallel with the guide rail 32, or a nozzle is provided on the slider 31, so that the spray header can be removed before or during the scraping. By spraying water or the like on the surface, the scraping effect can be increased. In the above description, the scraper mechanism 5 is provided between the supply elevator 11 and the roller conveyor 15, but may be provided above the supply elevator 11. In this case, the baking plate 1 which has been raised to the level of the roller conveyor 15 by the support claws 11a is temporarily stopped for transfer, so that scraping is performed at this transfer position. With such an arrangement, the supply elevator 11 and the roller conveyor 15 can be linearly and continuously arranged without installing the supply elevator 11 on the side.

Next, the brush mechanism 6 is shown in FIGS.
As shown in (1), a pair of upper and lower rotating roll brushes 40 having a spray header 41 and an air nozzle 42 for an air curtain (weir) are arranged in this order from the upstream side. The roll brush 40 is provided on the upper surface of the baking plate 1 (mainly scorched food).
The shaft 40a is disposed so as to be perpendicular to the firing movement direction, and has a length capable of cleaning from the trough 1b to the weir 1a. One end of the shaft 40a is rotatably supported, and the other end of the shaft 40a is connected to a drive motor 43 to rotate the roll brush 40. The rotation direction is set so that the contact portion of the roller brush 40 with the firing plate 1 moves in the direction opposite to the firing moving direction.

The spray header 41 has a nozzle 41
a, water or warm water is sprayed onto the upper and lower surfaces of the baking plate 1 at the brush position or on the upstream side of the baking plate 1 to wash the rolls during the removal by the roll brush or to swell the deposits prior to the removal to enhance the removal effect. ing. The hot water can use the waste heat of the heater 18 or the like. Air nozzle 4
Numeral 2 is for forming an air curtain that crosses the firing plate 1 by the air injected downward, and blocks the moisture remaining on the upper and lower surfaces of the firing plate 1 from migrating downstream. The blocked water escapes downward from the gap created between the firing plates by cooling with spray water or the like (the viscosity of water is much lower than that of oil or the like, and escapes from a slight gap). The invention is not limited thereto, and a water absorbing roll or a dryer may be used, or may be used in combination. The roll brush 40
When the roller conveyor 15 cannot transfer the baking plate 1 without a gap because the roller rotates in the opposite direction to the roller 15a of the roller conveyor 15, an upper roller 15b that contacts the weir 1a is also provided on the upper side, and The firing plate 1 is sandwiched between the rollers 15a and 15b from above and below, and
And send it to the side.

In the above configuration, the operation is as follows. (1) The fired plate 1 that has been raised by the support claws 11a of the supply elevator 11 is placed on the mounting table 3 by the pushing pusher 36.

At this time, if the lifting table 35 is set at the scraping position of the ascending limit, the scraper blade 30 serves as a guide, and the firing plate 1 can be positioned in the firing movement direction. Further, the stopper 34a performs positioning in a direction orthogonal to the firing movement direction. (2) The scraper blade 30 is moved by the drive cylinder 33 to scrape off the deposits on both contact surfaces of the firing plate 1. Brushing can remove oxides and the like of vegetable oil which are difficult to remove. In the case of a brush, the brush is worn by the contact surface corners, but since it is a blade, there is no such concern. When the scraping is completed, the elevator 3
5 is lowered to the lower limit, and the scraper blade 30 is returned to the original position. (3) The fired plate 1 is moved up and down by the transfer pusher 12
5 and is transferred to the roller conveyor 15 via the auxiliary roller group 37.

(4) The fired plate 1 on the roller conveyor 15 is
While being transported, the spray water is sprayed from the spray header 41 onto the upper and lower surfaces, and the attached matter on the upper and lower surfaces is removed by the roll brush 40. The scorched matter is reliably removed by the brush while being washed with the spray water or in a swollen state. The remaining moisture is blocked by an air curtain by the air nozzle 42 and is removed by dropping from a gap between the firing plates. (5) The fired plate 1 whose both contact surfaces and the upper and lower surfaces have been cleaned is transferred to the entrance side of the slide rail 17 by the roller conveyor 15. Here, the fired plate 1 is sent so as to be in contact with the previous fired plate. (6) Sintered plate 1 located on the entrance side of slide rail 17
The rack pin 2 meshes with the pinion 3 and is sent out by the rotating pinion 3. The next sintering plate 1 is continuously and similarly sent out. The fired plate downstream of the fired plate directly sent out by the pinion 3 is indirectly pushed through the fired plate and slides on the slide rail 17 at a constant speed to form a trough-shaped fired portion 21 with no gap. You.

(7) After the oil is applied to the baking section 21 having no gap by the oil applying device 13, the material is supplied from the material supply device 14 and is heated and baked by the heater 18. (8) The baked sheet-shaped baked food is taken out by a take-out device (not shown) including a conveyor or the like. (9) The fired plate 1 extruded from the exit side of the slide rail 17 is transferred onto the support claw 20a of the recovery elevator 20, and is supplied by the return conveyor or the like.
Will be returned to The above steps are repeated to produce a sheet-shaped baked food continuously.

In the above description, an example is shown in which the scraper mechanism and the brush mechanism are arranged between the supply elevator and the slide rail. However, the present invention is not limited to this, and the scraper mechanism and the brush mechanism may be incorporated in the process of returning the fired plate. Further, it is needless to say that the present invention can be applied to other continuous firing apparatuses in which independent fired plates are arranged to form a plate-shaped fired portion.
