Description

[Detailed description of the invention] (Field of industrial application) This invention relates to a rice loosening device for evenly loosening cooked rice immediately after cooking.

(Prior Art) Generally, the task of loosening freshly cooked rice is performed at home by housewives. However, if you want to industrially produce a large amount of loosened cooked rice, a considerable amount of labor is required and it is difficult to do it manually, so a mechanized loosening machine is used.

Conventionally, as shown in FIGS. 8 and 9A and 9B, this loosening machine 20 has a number of stirring rods 22 arranged radially around the outer periphery of a core rod 21 at predetermined intervals along the width direction. The one installed vertically is used. This loosening machine 20 is for rice 24 after cooking.
The loosening machine 20 is placed on the conveyance path 23 to be perpendicular to the conveyance direction, and the loosening machine 20 is applied to the cooked rice 24 being transferred on the conveyance path 23, and the stirring rod 22 loosens the cooked rice 24 by rotation. is relaxing.

(Problem to be solved by the invention) In the above-mentioned loosening machine, in order to ensure the loosening of cooked rice, models with stirring rods of various thicknesses and lengths have been proposed. Proposals include ones with different pitches and numbers of stirring rods, and ones with combinations of longer and shorter stirring rods.

However, although various proposals have been made for conventional rice loosening machines, the basic structure of the stirring rod, which rotates along the direction of rice transport, remains the same, so the rice has streaks in the direction of movement. rest,
The vertical strips of cooked rice between the striations, that is, between the stirring rods, are transferred without being loosened. As a result, the rice is not thoroughly loosened, and mixing causes so-called "clumps" and "kneading" phenomena. These phenomena significantly impair the taste of cooked rice, and in the current situation where more delicious rice is sought after, such deterioration in taste has become an extremely serious problem.

For this reason, in order to eliminate the above phenomenon, in reality, after loosening the rice with a loosening machine, the loosening process is performed manually, which is time-consuming and the work efficiency is not good. . In addition,
Since the imperfection of the loosening described above is due to the gaps between the stirring bars, it is also possible to reduce the spacing between the stirring bars, that is, the pitch. However, if this pitch is made small, the rice will be packed between the stirring rods, which may cause the stirrer to lift up and cause damage to the device.
Practical use is difficult.

The basic purpose of the present invention is to solve the above-mentioned problems, and to provide a loosening device that has a simple structure and can uniformly loosen the dough without requiring manual labor.

(Means for solving the problem) That is, in the rice loosening device of this invention, a plurality of loosening bodies are rotatably installed on a conveyance path for transferring cooked rice so as to intersect with the transfer direction. A plurality of wire bodies having a predetermined lead angle are disposed at positions that maintain a predetermined distance from the axis of the loosening body, and the loosening body has two or more types of wire bodies having different lead angles. It is characterized by consisting of.

In addition, it is desirable to install a plurality of loosening bodies by alternately arranging two types of loosening bodies having positive and reverse lead angles.

(Function of the device) According to this device, the loosening body is pressed against the cooked rice, and the wire body is oriented in a direction having a predetermined angle with respect to the advancing direction of the cooked rice (based on the lead angle). , scratch the rice. When this cooked rice hits a loosening body provided with wire bodies having different lead angles, the cooked rice is scraped in a direction different from the above-mentioned direction due to the lead angles. Therefore, the cooked rice is scratched in a plurality of different directions to loosen it evenly.

In addition, if the loosening bodies are installed by alternately arranging two types of loosening bodies whose lead angles are positive and opposite, the cooked rice will be scraped in two symmetrical directions, and the rice will be loosened more evenly and efficiently. It will be.

(Example) An example of this invention will be described below based on FIGS. 1 to 4.

To explain a type of loosening body used in this embodiment, reinforcing rods 3, 3 are radially arranged around the outer periphery of the core material 2.
are erected, and a circular reinforcing frame 4 whose radius is the length of the reinforcing rod 3 is fixed to both sides of the core material 2.

Furthermore, four wire rods 5 having a lead angle α in the longitudinal direction are arranged at regular intervals on a virtual outer peripheral surface having the same radius as the reinforcing frame 4, and both ends of each wire rod 5 are It is fixed to the reinforcing frame 4 by welding or the like, and the central part of the wire 5 is also fixed to the reinforcing rod 3 by welding or the like, so that the loosened body 1a
is configured. Note that this lead angle α is determined so that the wire 5 is twisted approximately 90 degrees in the longitudinal direction.

Moreover, the unraveling body 1b is similarly constructed using a wire rod having the lead angle of −α.

Note that the surfaces of the above-mentioned constituent members of the loosened bodies 1a and 1b are coated with fluorine resin to prevent sticky adhesion of cooked rice.

The loosening bodies 1a and 1b are rotatably installed on a conveyance path 8 through which the cooked rice 7 is conveyed so that the core material 2 is perpendicular to the conveyance direction, and are each connected to a rotation drive device (not shown). ing.

In addition, during this construction, the distance between the wire rods 5 and 6 and the upper surface of the conveyance path 8 is set to 2, which is approximately equal to the grain size of the rice.
~3mm.

To explain the operation of this device, the transport path 8
At the top, the cooked rice 7 is transferred to the right in the figure, and the loosened bodies 1a and 1b are rotated in the direction of arrow A, respectively. The cooked rice 7 moving on the conveyance path 8 is
It is bitten by the loosening body 1a, and is pushed apart in a certain direction by the wire 5 according to the lead angle α,
It is cut into strips to create a striped pattern.

This cooked rice 7 is further bitten into the next loosened body 1b. In the loosening body 1b, since the wire rod 6 has a lead angle of -α, the cooked rice 7 is scraped in the opposite direction to the wire rod 5, and the cooked rice 7, which has a striped pattern, is cut by crossing it, and the cooked rice 7 is trussed. The cooked rice 7 is divided so as to leave net or scale-like streaks, and the cooked rice 7 is evenly loosened.
No occurrence of so-called "clumps" or "kneading" was observed.

Moreover, since the above-mentioned loosening bodies 1a and 1b do not have a protruding structure (stirring rod) unlike conventional loosening machines, they are easy to handle and can be cleaned easily. Moreover, unlike the conventional example, the lifting phenomenon does not occur, so the device is less likely to be damaged and has superior durability.

In the above embodiment, the loosening bodies 1a and 1b are forcibly rotated, so by appropriately adjusting the moving speed of the conveyance path 8 and the rotational speed of the loosening bodies, the cooked rice can be divided into smaller pieces efficiently. It becomes possible to loosen it like this. Further, the loosening body can also be rotated by the moving force of the conveyance path without being forced to rotate.

In addition, in the above embodiment, the number of loosening bodies is two, but it may be three or more. In that case, two or more types of loosening bodies with different lead angles are used to efficiently loosen the cooked rice. It is desirable that adjacent loosening bodies on the conveyance path be of different types so that the loosening bodies can be of different types.

Further, in the above embodiment, wire rods were used as the wire bodies, and the number of wire rods was four, but the number is not limited and may be 6 to 8. Further, the wire body is not limited to a wire rod, but may be a band material arranged so that its thin side faces toward the outer periphery.

Next, FIGS. 5 to 7 show a loosening body 10 in another embodiment.

That is, reinforcing rods 13, 13 are radially set up on the outer periphery of the core material 12, and have a lead angle β with respect to the longitudinal direction on a virtual outer circumferential surface having the same radius as the length of the reinforcing rods 13. Eight wire rods 15 are arranged at regular intervals, and each wire rod 15 is provided with a reinforcing rod 13.
is fixed by welding etc.

Note that both ends of each wire 15 are bent toward the core 15 and fixed to the core 12, and the lead angle β is determined so that the wire 15 is twisted 180 degrees in the longitudinal direction. By arranging this loosening body 10 and other loosening bodies with different lead angles on the conveyance of cooked rice, the loosening of cooked rice is performed reliably and efficiently.

Although the invention of the present application has been described as a loosening device, it does not mean a single-function device having only a loosening function, but it may be incorporated into a cooling device equipped with a fan or the like, or incorporated into a conveying means. It can also be applied to things such as clothes.

(Effects of the invention) As explained above, according to this invention, a plurality of loosening bodies are rotatably installed on the conveyance path for transporting cooked rice so as to change the direction of transport, and the loosening bodies are in a position that maintains a specified distance from the body axis,
A plurality of wire bodies having a predetermined lead angle are arranged, and the loosening body is made of two or more types with different lead angles of the wire bodies, so that the cooked rice can be efficiently cooked with a simple structure. It has the effect of being able to definitely loosen up.
