Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Application of the Invention The present invention can be used in the fields of food manufacturing and food machine manufacturing.

2. Description of the Related Art Several techniques are already known for continuously manufacturing foods by mixing ingredients into fluid dough and baking it. A well-known technique is the production of baked clay confectionery such as Imagawa-yaki, in which a large number of molds are circulated, a fixed amount of fluid dough is filled into the molds, and a small amount of the dough is baked. After solidifying, the product is baked completely, and then the mold is opened and the product is removed. Supplying dough, supplying bean paste, fitting molds, baking,
There are also commercially available devices that can fully automatically perform operations such as disassembling the mold, taking out the product, cleaning the mold, and applying oil to the mold.

In the case of Imagawayaki, the shape of the product has a small ratio of diameter to thickness and is chunky, and the filling, the red bean paste, is contained in the center of the product and separated from the dough, so it solidifies. The fabric structure at the end is strong, so you don't have to worry about it breaking even if you handle it a little roughly. However, there are almost no methods or devices for continuously baking extremely fragile foods such as okonomiyaki, which contain a large amount of ingredients mixed into the dough and have a large diameter-to-thickness ratio. unknown. Takoyaki is similar in composition to okonomiyaki, but since it is spherical, it retains its shape well, and the technology for mass production seems to have already been established.

C. Problems to be Solved by the Invention The present invention solves problems that are not well known in conventional continuous mass production systems, in which a large amount of ingredients are mixed in the dough such as okonomiyaki. The object of the present invention is to provide a method and an apparatus that enable continuous mass production of food products, which are extremely fragile due to their large diameter-to-thickness ratio.

Problems to be solved by the present invention include: (A) The product is extremely easy to deform and break.

(B) The supply of dough and ingredients, their mixing, shaping, baking, etc. should be carried out uniformly and efficiently.

2.Means to solve problems The method of the present invention has the following configuration.

(A) Considering that the product is extremely deformable and fragile, the dough and ingredients are fed into a heat-resistant tray, pressed and formed into a plate shape, and then baked to make the product. The products are handled in trays.

B) A plurality of molds capable of holding trays are attached to an endless transfer means, and the transfer means is driven while trays are sequentially fed into the molds. A fixed quantity of fluid dough is filled into the tray and a fixed quantity of ingredients is supplied.

Next, the top surface of the tray is pressed to make it flat, and heat rays are irradiated to bake the food in the tray. When baking is completed, the baked product is removed from the mold along with the tray.

Next, these two configurations will be explained in detail.

Regarding (A), a heat-resistant tray made of aluminum foil, for example, can be mentioned.

Regarding (B), an example of the endless transport means (a) is an endless chain conveyor. It is sufficient to attach a plurality of molds to this.

Although the conveying means is continuously or driven, it goes without saying that the feeding of the tray, the pressing of the upper surface of the tray, and the removal of the baked product must be carried out in synchronization with the movement of the mold.

(b) In order to sequentially supply trays to molds, for example, the trays are stored in a stacked state in a tray holder with an open top, and the transfer means has a structure that can rotate between the tray holder and the tray holder and can be raised and lowered. Attach a suction cup to the tip of an arm that has a suction cup, and connect this to a vacuum pump via a tube (the valve should have a structure that allows switching between a vacuum state and atmospheric pressure). The arm rotates directly above the tray holder, and when it descends and the suction cup at the tip touches the tray, a vacuum is transmitted by the action of the valve and the tray is attracted, and the arm rotates. When the tray comes directly above the mold, a valve may be switched, atmospheric pressure is transmitted, and the tray falls into the mold by its own weight. However, in the case of small-scale implementation, the trays can be fed into the mold manually.

(C) In order to automatically fill a tray with a fixed amount of dough, a tank is installed to store the dough, and a valve is attached to the bottom of this tank, and by adjusting the opening and closing time of the valve, a certain amount of dough flows out under its own weight. Alternatively, a constant amount may be supplied by connecting a discharge pump to the tank and adjusting the operating time of the discharge pump. Note that if the dough is allowed to stand still, the water and the dissolved material are likely to separate, so it is advisable to provide a stirring means in the tank.

(d) As a means for feeding the ingredients into the cup, there is a combination of a feeder with a built-in vibrator and a hopper with a built-in weight detection means. That is, the ingredients are gradually dropped into the hopper by vibration of the feeder, and when a certain weight is reached, the hopper is opened and the ingredients are dropped into the tray. However, raw shredded cabbage, which is commonly used as an ingredient, may become intertwined with each other depending on how it is cut, making it impossible to feed it at a uniform speed with a vibrator-type feeder, and feeding it manually may be recommended. be.

Ingredients include shredded cabbage, chopped red pickled ginger, pieces of beef, pieces of pork, pieces of squid meat, tempura, and optionally udon noodles and Chinese soba noodles. In order to make the ingredients and dough blend better, it may be a good idea to add more dough to the top of the tray after feeding the ingredients into the tray (θ). Either by a stamp that descends with a constant stroke and engages with the top surface of the tray, or by attaching a roller in contact with the top surface of the tray and rotating the roller in synchronization with the transport speed of the tray, thereby removing the top surface of the tray. Make sure to even out. In these cases, to prevent the nodley from deforming and breaking due to pressure,
If the mold is open downward, it is preferable to attach a stand or roller to the bottom of the tray.

In order to avoid contamination of the compression means with fluid fabric, heat irradiation means as described below is provided before the compression means.
Alternatively, a steaming means or the like may be installed to lightly solidify the upper surface of the tray, or a heating means may be attached to the compression means to lightly solidify the contact surface with the compression means at the same time as the compression.

In the latter case, use a stamp or roller as a compression means and make it hollow and pass steam through it.
Alternatively, the purpose could be changed by embedding an electric heater.

It is not hard to imagine that even better results could be obtained if the compression means were coated with Teflon.

(f) As a method for baking the food in the tray, a heat irradiation means such as a red-hot heater (such as a Schwank heater), an infrared heater, a far-infrared heater, etc. may be used. Heat ray irradiation may be performed not only from the top surface but also from the bottom surface, and may also be performed by other heating means, such as an open flame,
It is also possible to use steam, etc. (Co., Ltd.) Once the food is baked, it is removed from the mold while still in the tray. For this purpose, for example, the trays filled with food can be removed from the mold, or a mold with an open bottom can be used and a lift can be installed that can be raised and lowered through the bottom of the mold, thereby lifting and removing the tray filled with food. A method is shown. However, when implementing the present invention on a small scale, the removal can also be performed manually.

Next, the apparatus of the present invention will be specifically explained based on the attached drawings.
