Description

DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to a food molding machine that uses a machine to mold food products such as sushi rolls that were previously molded by hand.

"Prior Art" Food molding machines are known that automatically mold foods such as nigiri sushi, which were conventionally molded by hand. This one is JP-A-58-
As disclosed in Japanese Patent No. 3660, the rice fed into the chute is connected to the chute, and
The food is pushed out from the chute side through a food passage whose tip end is constricted by a drive mechanism, and the food pushed out from this food passage is conveyed by a belt conveyor and automatically formed into sushi-shaped, rice ball-shaped, etc. by a forming mechanism at a predetermined location. It is something to do.

"Problems to be solved by the invention" However, in the conventional food molding machine,
The problem was that the mechanism was complex, large, and expensive.

An object of the present invention is to provide a convenient food molding machine that solves the above-mentioned problems of conventional machines and can easily mold foods such as nigiri sushi even at home. .

"Means for Solving the Problem" A plurality of rollers are rotatably arranged in a housing with their outer peripheries spaced apart and facing each other, a food passage is formed between these rollers, and a food passage is provided between the plurality of rollers. A rotation drive mechanism connected to the plurality of rollers for rotation in a predetermined direction, a bottom molded container having a molding recess and provided below the food passage with the molding recess facing each other; A container is connected to both containers and the rotational drive mechanism, and is moved in conjunction with the rotation of the plurality of rollers to open the upper side while keeping the lower side of both containers closed from the state in which the opposing surfaces of the two containers are in close contact with each other. a molded container opening/closing mechanism that brings the facing surfaces of both containers into close contact again, opens the bottom sides while keeping the top sides of both containers closed, and brings the facing surfaces of both containers into close contact; When the upper sides are opened, the food sent from the food passage is stored in both containers and compressed between the molding recesses, and when the lower sides of both containers are opened, the molded food is discharged downward. I have to.

"Operation" When the plurality of rollers are rotated by the rotary drive mechanism, the food between the plurality of rollers is forcibly fed into the bottom forming recess and the upper forming recess, which are open at the top. The opposing surfaces of the bottom molded container and the top molded container are brought together and compressed, and then the lower sides of both containers are opened and the molded food is discharged from the insides of both containers.

"Effects of the Invention" The structure is simple, the device can be made smaller, the cost is low, and foods such as sushi and rice balls can be easily formed at home.

Next, the operation of the food molding machine configured as described above will be explained.

First, a plate is placed on the turntable 52, and the container 53 is filled with food before being formed, that is, cooked rice.
A part of it is transferred from the food supply hole 54 to the rollers 18 and 19.
When the handle 50 is rotated in a predetermined direction, the turntable 52 rotates via the rotating shaft 45, pulley 46, belt 48, tension pulley 49, large pulley 4, etc., and the small gear 47 and large gear rotate. The horizontal shafts 20 and 21 are connected to the first
In the figure, they rotate in the directions of arrows A and B, respectively.
Then, the roller 18 and disc 23 shown in the figure attached to the horizontal shaft 20 rotate in the same direction as the horizontal shaft 20 (in the direction of arrow A), and the roller 19 and disc 23 attached to the horizontal shaft 21 rotate horizontally. It rotates in the same direction as the shaft 21 (in the direction of arrow B), and as a result, the hanging members 37 of the yokes 33 and 34 are pulled up against the force of the spring 44 via the links 40 and 41, and the bottom molded container 29 and the top The molded container 30 is connected to the support pin 26
The lower side of the molded container 28 opens. Next, both the hanging members 37 are pushed down via the links 40 and 41, and the opposing surfaces of the bottom molded container 29 and the top molded container 30 are brought into close contact with each other. Subsequently, the hanging member 37 is connected via the links 40 and 41.
is pushed down against the force of the spring 43, the bottom molded container 29 and the upper molded container 30 rotate about the support pin 27, and the upper side of the molded container 28 opens. Then, the food between rollers 18 and 19 is transferred to rollers 18 and 1.
9 forcibly sent downward by the teeth 22 of the bottom molded container 29 and the upper molded container 30, respectively, into the recesses 31, 3.
It is supplied between the two.

Furthermore, when the handle 50 is continued to be turned, the hanging member 37 is pulled up as described above, and the bottom molded container 29 and the upper molded container 30 are rotated around the support pin 27, compressing the material between the recesses 31 and 32, and forming the bottom part. The opposing surfaces of the container 29 and the upper molding container 30 are brought into close contact to form sushi balls, and when the handle 50 is further turned, the lower side of the molding container 28 opens and the molded sushi balls are discharged and dropped from the molding container 28. As a result, the formed sushi balls are sequentially arranged in the circumferential direction on a plate placed on the turntable 52.

According to this embodiment, since it does not require power such as a motor and has a simple structure, it can be downsized, and even at home, it is easy to form foods such as sushi and rice balls and automatically place them on a plate. can be arranged according to Further, in the embodiment, the recess 31 formed in the bottom molded container 29, the upper molded container 30,
Although the shape of No. 32 is used for forming nigiri sushi or rice balls, the shape is not limited thereto, and may be any desired shape for forming food. Also,
In the embodiment, the teeth 2 of the rollers 18, 19
2 was set in the direction shown in FIG. 1, and the rice before forming was sent forcefully downward.
You can also adjust the feeding rate by changing the direction of the rice.
Further, the distance between the rollers 18 and 19 can be changed and adjusted as appropriate, and the feeding state of the rice can be adjusted by eccentrically rotating the rollers 18 and 19. Further, in place of the teeth 22 of the rollers 18 and 19, protrusions of other shapes may be provided to feed the unformed food product downward.
