Description

[Detailed description of the invention] [Industrial application field] The invention is applicable to nigiri rice, Makunouchi bento, nigiri sushi,
The present invention relates to a new automatic fixed-quantity feeder for rice that continuously and automatically supplies a fixed amount of rice as a semi-formed product by pressing when mass-producing lump rice such as Inari sushi.

[Conventional technology]

In the past, the process of turning rice into fixed quantities was done by hand or by a similar method.

[Problem that the invention attempts to solve]

However, the manual or similar methods described above are slow and have poor work efficiency.
It was unsuitable for mass production, and had other drawbacks such as requiring skill to make the quantities uniform.

[Means to solve the problem]

The purpose of this invention is to solve the above-mentioned defects by automatic mechanization.In other words, in the left and right sides of the space of a predetermined width formed by the front plate and the rear plate, A pair of left and right compression plates that are capable of distance movement and vertical movement are vertically divided into two by inserting a partition plate in the same center that is capable of vertical movement of the compression plates and vertical movement of the compression plates, and There is a metal passage with both upper and lower ends open, and the width narrows as it goes downwards, and the cutting edge advances and retreats laterally toward the center of the opening at the lower end of the metal passage, and when moving forward, it moves to the left and right of the lower end of the partition plate. A pair of left and right knives are provided that abut or are close to both sides and fully open the lower end opening of the feed passage when retracting, and the space between the left and right compression plates is expanded during the upward stroke. During the downward stroke, the rice in the passage is compressed and moved downward by a predetermined distance by operating in a compressed state, and during the upward stroke, the food in the compressed state is compressed and moved downward by a predetermined distance. It is characterized in that the knives on both the left and right sides are configured to move in a separated state, and the knives on both the left and right sides are formed so that as they move forward, they cut off only the descending portion of the rice in the pressed state.

[Background of the idea]

Upon completion of this invention, we produced a prototype without a partition plate. However, this prototype machine works well for small fixed quantity molded products such as nigiri sushi and Inari sushi, but it works well for large fixed quantity molded products such as large nigiri rice (approximately 200 g) and Makunouchi bento (approximately 200 g). In this case, even if the prototype is made larger, the squeezing force of the compression plates on both the left and right sides will not reach the center of the molded product, and the adhesive force (frictional resistance ) became larger, it was found that it did not function as well as the above-mentioned small quantitative molded product. There is a method of adding a small amount of oil to the rice to reduce the frictional resistance, but this method reduces the taste, which is undesirable, and adding oil is time-consuming. As a result of trial and error, the inventor of this application has created an automatic metering feeder of the present invention that works well even for large metered molded products that do not contain oil by inserting a partition plate between the compression plates on both the left and right sides that only moves up and down together with the compression plates. We have come to offer it.

[Effect]

As shown in the above embodiment, the present invention is capable of supplying a fixed amount of rice to the next process in a so-called two-piece continuous state as a lump-shaped molded product. The left and right moldings to be cut off are each 100g, and two pieces are supplied to the next process.In the case of large moldings such as rice for Makunouchi bento (for example, 200g),
Take out 100g each for the left and right sides and combine them into 200g using a mold in the next process. Two pieces are placed side by side into one mold, and in the next molding action, one
It is something that can be summarized individually. If there is no partition plate, the contact area is small because the rice only contacts the left and right compression plates, and pressing down alone cannot overcome the adhesive force between the rice and the front and rear plates, that is, the frictional resistance. When the rice comes into contact with the plate, the contact area is doubled, and when the compression plate begins to apply squeezing force to the rice as it descends, the frictional resistance between the rice and the compression plate and the partition plate increases between the rice and the front and rear plates. This allows the rice to move downward by overcoming the frictional resistance.

[Effect of idea]

Since the present invention is as described above, it not only has a large labor-saving effect due to automatic feeding and greatly contributes to improving work efficiency, but also enables mass production by using two pieces as described above, and also allows for uniform molded products. It has the advantage that it can be obtained continuously, and it does not require manual experience or skill to obtain a quantitative amount, which helps to reduce labor costs.
The compression plate that moves up and down and slides laterally increases the contact area with the rice, overcomes the frictional resistance of the rice against the front and back double-sided plates, and is reliable even for large quantitative molded items such as large rice balls and Makunouchi bento boxes. It is possible to send out a fixed amount in a fixed amount, and as mentioned above, the taste does not deteriorate due to the addition of oil, which is highly effective in meeting the needs of the industry.
