Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic application device for automatically applying egg liquid to the surface of bread dough before baking in a bakery factory.

[0002]

2. Description of the Related Art In breadmaking, egg liquid is applied to the surface of bread dough before the baking process in order to illuminate the surface of the bread to be produced. This application work was carried out by brush application of egg liquid with human hands. However, such manual work cannot be expected to improve manufacturing efficiency or uniform quality.

In consideration of mechanization, various problems occur in the mechanization of brush coating. That is, a cup (baking type)
In the case of a product in which the dough is stored in the cup, if the brush hits the outer periphery of the cup, the egg liquid will be scraped off by the outer edge of the cup, and the egg liquid will be wasted much, and the surface of the dough inside the cup will not be suitable. It is not painted. Further, in the case of a product having an uneven surface on the surface of the cloth, there is a problem that it cannot be applied evenly by brush application.

Therefore, the present invention proposes an apparatus for automatically applying egg liquid to bread dough.

[0005]

An automatic egg yolk coating apparatus according to the present invention is provided with a conveyor section for carrying a top plate on which a target egg yolk coating material is placed, and a position of the top board provided in the middle of conveyance. A sensor unit for detecting, an egg yolk tank provided with a cooling mechanism or a cold keeping mechanism, and egg yolk supplied from the egg yolk tank, spraying the egg yolk toward the conveyed top plate, and the spraying operation is performed as described above. And a spray section controlled by a signal from the sensor section.

With respect to the bread dough on the top board thus conveyed, the sensor unit detects that the top board is conveyed to a predetermined position, and the egg solution is sprayed into the top board. As a result, the egg liquid is evenly attached to the surface of the bread dough placed on the top plate, and the egg liquid application work is automatically performed.

The device of the present invention further includes a cover portion surrounding the spray portion, and a suction pipe connected to the cover portion.
A discharge mechanism section having an exhaust blower connected to the suction pipe is additionally provided.

Therefore, among the egg liquids sprayed and sprayed, the egg liquid floating without adhering to the top plate or the bread dough stays in the cover portion without being diffused. The fog is prevented from diffusing into the plant, and the plant is kept hygienic.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described. The coating apparatus shown in the embodiment includes a transport mechanism unit 1, a sensor unit 2, a spray machine body 3 for incorporating a predetermined mechanism,
The egg liquid tank unit 4, the spray unit 5, and the discharge mechanism unit 6 are included.

The transport mechanism section 1 is composed of a transport conveyor and a drive mechanism (not shown) for the transport conveyor, and the conveyor has a size suitable for transporting the top plate A generally used in the bread making industry. is there. Further, the sensor unit 2 detects that the top plate A has reached a predetermined position of the conveyor 1, and employs a proximity switch or other suitable structure.

The spraying machine body 3 can be located near the conveyor 1 from the side of the conveyor 1 and can be located on the side of the conveyer conveyor 1, and a supporting portion 32 provided above the supporting portion and located above the conveyor. It is provided at the lower part of the support part and is provided with a leg stand part 33 provided with casters on the bottom surface. A receiving tray 34 is provided on the upper surface of the leg stand 33 at a position below the conveyor 1.

The egg liquid tank portion 4 and the spray portion 5 are incorporated in the carrying portion 32 of the spraying machine body 3 described above. The egg liquid tank portion 4 has a jacket structure tank, and cold water is supplied to the jacket portion so that the egg liquid is removed. Keep at a low temperature to prevent it from hardening or spoiling. Needless to say, another cooling mechanism may be adopted instead of cold water.

In the spray section 5, a suitable number of commercially available automatic spray guns 51 are arranged above the conveyor 1, and the egg liquid tank 4 is provided.
From the egg liquid supply pipe 52 and a compressor (not shown:
A valve opening / closing air pipe 53 and a spraying air pipe 54 may be connected to each other.

The discharge mechanism portion 6 is composed of a cover portion 61, an exhaust blower 62, and a suction pipe 63 connecting and connecting the cover portion 61 and the exhaust blower 62.

The cover part 61 is incorporated in the machine body 3 and is provided so as to surround the periphery and the upper surface of the spray part 5 carried by the carrying part 32.

When the dough B to be coated with egg liquid is arranged on the top plate A and the top plate A is sequentially supplied to the conveyor 1 and conveyed, the top plate A is surrounded by a predetermined position (enclosed by the cover portion 61). Space (spray position), the sensor unit 2 senses and the spray unit 5 is operated. That is, by spraying the spraying air by opening the valve of the automatic spray gun 51 for a certain period of time or until the valve is closed by the detection of the detachment sensor (required time), the egg liquid C is attracted and sprayed in a mist state. By spraying the egg liquid C, the egg liquid C is uniformly attached to the surface of the bread dough B.

Therefore, by sequentially supplying the top plate A on which the bread dough B is placed, it is possible to apply the bread dough continuously and efficiently.

Further, since the egg liquid spraying portion is covered with the cover portion 61, the sprayed egg liquid C adheres to the surface of the bread dough A, or floats in the atmosphere except those adhered on the top plate A. Alternatively, it collects in the tray 34 below the conveyor. Then, when the exhaust blower 62 is operated, the atmosphere inside the cover portion 61 is discharged to the outside of the cover portion space through the suction pipe 63. Of course, it goes without saying that the exhaust blower 62 is additionally provided with a mechanism for removing the atomized egg liquid C such as a filter.

Therefore, the egg liquid C sprayed and sprayed is sucked by the discharge mechanism 6 except for the one adhering to the top plate A or the bread dough B or falling and staying in the pan 34, and is sprayed into the factory. Will be prevented from spreading.

The present invention is not limited to the above-mentioned embodiment, and if the egg liquid maintained at a low temperature is sprayed on the bread dough to be transported, the transport mechanism and the spray mechanism have a mechanism structure different from that of the above-mentioned embodiment. You may adopt one.

[0021]

As described above, according to the present invention, a conveyor section for conveying a top plate on which bread dough is placed, a sensor part for detecting that the top plate has reached a predetermined position, an egg liquid tank, and an egg. An automatic egg yolk coating device equipped with a spray unit for spraying the liquid realizes automatic mechanization of manual egg yolk coating, which contributes to improvement in production efficiency of the bakery industry.
