Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an improvement of the mortar structure in a rice cake pounding machine.

[Conventional technology]

The mortar structure of a mochi pounder is known in Japanese Patent Publication No. 38-14380, Japanese Utility Model Publication No. 38-5787, and the present applicant. Jitsukaiaki proposed by himself
It is well known as seen in No. 50-137397 and No. 55-128989.

[Problems to be solved by the invention] However, since the mortar is formed into a bowl shape as a whole, the following problems arise when it works to pound rice cakes. In other words, since the entire mill is rotated, the entire glutinous rice stored in it is rotated together while exerting friction against the mill, and as a result, in the process of being pounded up,
A large amount of air gets mixed into the rice cake.

As a result, the specific gravity of the rice cake decreases, and
The air has poor thermal conductivity, so if you boil or bake the pounded mochi before eating it, the outer layer of the mochi will evaporate before the center of the mochi is sufficiently heated. The mochi will quickly burn, melt and run off, or even expand and burst locally, making it impossible to obtain high-quality mochi.

In addition, especially when the glutinous rice is in a particle state that has not yet been turned into a paste, it is carried around with the mortar, so the glutinous rice accumulates in localized lumps at the point where it is caught by the cutting blades. On the other hand, a pestle moves only the center of the mortar up and down, so it is not possible to pound the entire sticky rice evenly and efficiently in a short period of time.

[Means for solving problems]

The present invention aims to solve the above problems with its extremely simple structure without requiring any special modifications to the rotary drive mechanism of the mortar. It is characterized in that it consists of an upper fixed ring and a lower rotation receiving cylinder that communicate with the core, and that fixed blades for turning back are exposed inside the ring.

〔Example〕

Hereinafter, the specific structure of the present invention will be described in detail based on the illustrated embodiment. In FIGS. 1 and 2, which schematically show the entire mochi pounding machine, 10 is the machine casing of the mochi pounding machine, and the upper part of the mochi pounding machine is A lifting shaft 12 of the punch body 11 is supported on the shaft. Reference numeral 13 denotes a flywheel that is rotated around a horizontal axis by a motor (not shown), and a crank arm 14 that is projected from its eccentric position.
is pivotally connected to the upper end of the lifting shaft 12 via the horizontal rod 15, so that the rotational movement of the flywheel 13 is converted into a reciprocating lifting movement of the punch body 11. 16 is the operation panel, 1
7 is a water supply nozzle, 18 is a regulating valve for the nozzle 17, and 19 is a support.

On the other hand, a mortar body A facing the punch body 11 is installed at the bottom of the machine casing 10, and this is assembled in a concentric communication state from an upper fixed ring 21 and a lower rotating receiving cylinder 22 as described below. It is something that was given.

That is, in FIGS. 3 to 5, which are extracted and enlarged, the fixed ring 21 is cast from an aluminum alloy as a so-called bottomless round body, and an outward horizontal opening flange 23 is projected from the upper part. ing. Reference numeral 24 denotes a required number of support stays that are fixedly erected from the lower part of the machine casing 10, and the opening flange 23 of the fixed ring 21 is attached to the upper end of the support stay with the bolt/nut 2.
5 etc., it is preferably removably attached and fixed. However, the fixed ring 21 may be fixedly installed in the machine casing 10 of the rice cake pounding machine by means instead of the support stay 24 or the bolt/nut 25.

Next, the lower rotation receiving cylinder 22 is also formed from aluminum alloy casting into a bottomed bowl shape or funnel shape, and its almost hemispherical inner wall surface is continuous with the inner wall surface of the fixed ring 21, so that the inner wall surface of the fixed ring 21 is connected to the inner wall surface of the fixed ring 21. Aligned flush. In that case, in the illustrated example, the parting line L between the fixed ring 21 and the rotation receiver 22 is
Although it is set at a position approximately equal to half of the total depth of , as long as the above-mentioned line L faces a lower position than the average top surface of the glutinous rice M stored in the mortar A, The height of the line L can be set freely.

In addition, in the illustrated example, at the line L, the fixed ring 2
1 and the rotation receiving cylinder 22 are simply joined together, but instead of this, they may be fitted in a concave-convex manner. If the receiving cylinder 22 rotates without any problem with respect to the fixed ring 21 and particles of glutinous rice M and moisture do not scatter from the mutual gap, it is worthy of adoption. The entire inner wall surface of the mortar body A is treated with so-called Teflon or the like to make it non-adhesive, but the treated film is not shown.

Reference numeral 26 denotes a horizontal mounting flange projecting from the lower part of the rotation receiving cylinder 22, which is connected to a rotary disk 28 which is rotationally driven by a motor 27, and is connected to a bolt/mounting flange.
Preferably, they are removably fixed by a nut 29 or the like so that they rotate together with each other. 30 is a general term for a power transmission mechanism between the rotary disk 28 and the motor 27, and includes, for example, a belt, a pulley, a gear, etc. The receiving tube 22 is rotated at a reduced speed of about 60 rpm by the motor 27.

However, instead of the fixed connection means between the mounting flange 26 and the rotary disk 28, for example, as shown in FIG. ,
The receiving cylinder 22 may be fixed to a rotating shaft 32 rotationally driven by a motor 27 and rotated integrally with each other, and the transmission mechanism 30 for the rotational power can be freely selected.

Furthermore, B is a fixed blade for turning back facing the inside of the mortar body A, which is suspended along the inner wall surface of the mortar body A, and its lower end 33 is connected to the part between the fixed ring 21 and the rotation receiving cylinder 22. Crossing the line L,
It extends until it enters the interior of the receiving tube 22 by a certain depth D, so that it can continue to cut back the glutinous rice M from start to finish.

In this regard, in FIGS. 3 to 5, when the fixed blades B are viewed from the plane of the mortar body A, they are preferably arranged as a pair of opposing blades, each attached to the vicinity of the lower part of the inner wall surface of the fixed ring 21 with a bolt/nut 34 or the like. is removably attached and fixed, and the space between the upper end of the blade B and the opening flange 23 of the fixed ring 21 is opened as a height gap H through which the glutinous rice M can escape as it rises. . 35 is its mounting seat.

Moreover, when each blade B is viewed from the front of the mortar body A, its turned plate surface portion 36 intersects the vertical center line Y-Y of the mortar body A at a certain acute angle α,
From the relationship with the rotation direction P of the receiving tube 22,
The glutinous rice M is released diagonally downward and made to flow. Also, the cut-back plate surface portion 36 when viewed from the same plane is shaped into a circle of the mortar body A at its attachment fixing point so that the glutinous rice M can escape and flow toward the center of the mortar body A in relation to the direction of rotation P. The angle β formed by the tangent line XX is an obtuse angle, giving it a so-called twist.

According to such a form of the fixed blade B, Part 2
Because the individuals are arranged as a pair facing each other,
It becomes possible to make each of them relatively compact, and together with the intentional opening of the above-mentioned escape gap H, it is effective to reduce the lumps of glutinous rice M that are dammed up and accumulated on the cut-back plate surface part 36 during the rice cake pounding action. It can be said to be beneficial in that it can be dispersed and milled with high efficiency while uniformly cutting the entire sticky rice M.

However, as long as the cut-back plate surface portion 36 is given an obtuse twist angle β or an acute crossing angle α, and the lower end portion 33 extends beyond the parting line L and enters into the rotation receiving cylinder 22. Of course, the fixed blades B may be in the form shown in FIGS. 7 to 9, and one of them may be attached and fixed to the opening flange 23 of the fixed ring 21.

In other words, in this modification, the cut-back plate surface portion 36
A continuous cover plate surface portion 37 is provided at the upper end of the rice cooker, and by standing up from the opening flange 23 in an inclined state, overflow of the rising glutinous rice M is prevented. Since the other configurations are substantially the same as the above basic example,
Although the detailed explanation will be omitted and only the numbers corresponding to those in FIGS. 3 to 5 will be written in the figures, this fixed blade B may be attached and fixed to the machine casing 10 of the rice cake pounding machine, and From parting line L to sticky rice M
As long as particles and moisture do not scatter, it may be fixedly installed so as to be introduced into the mortar body A from between the fixed ring 21 and the rotation receiving cylinder 22.

[Effect]

When using the mortar body A of the present invention configured as described above, when the mochi pounding action is performed, the upper fixed ring 2
10, only the lower receiving cylinder 22 is rotated in the direction of movement of the arrow P described above.
As shown in , the parting line L
A unit amount of glutinous rice M housed inside taller than
In particular, at the initial stage of its particle state, only a certain amount of the lower mass layer _M1 , which has sunk and accumulated in the receiver tube 22, is rotated together due to the frictional force with the receiver tube 22, and its fixation is achieved. A certain amount of the upper mass layer M ₂ facing inside the ring 21 does not rotate,
Only simple up and down movements will be performed.

In other words, between the upper lump layer M ₂ and the lower lump layer M ₁ of the sticky rice M, a fluctuation action such as the so-called shifting of the ground occurs with the above-mentioned parting line L as the boundary, and the upper lump layer M ₂ is not subjected to the rotational centrifugal force of the receiving cylinder 22, but is stimulated by the movement of the lower mass layer _M1 , and collapses as it is. Therefore, when viewed from a plane as shown in the same figure, the glutinous rice M does not accumulate and form lumps only in the areas dammed by the fixed blades B for turning, and the air They do not allow time or space for preservation.

As mentioned above, the upper lump layer _M2 is likely to collapse, but in this case, the lower lump layer M facing the center of the mortar body A is depressed as a recess S by the descending punch 11, so that the lower lump layer M2 is easily collapsed. The upper lump layer _M2 of the rice M immediately and evenly falls from the peripheral position into the recess S and concentrates thereon, so that the crushing force of the pestle 11 can be efficiently applied to the glutinous rice M. Therefore, the processing time per unit amount can be significantly shortened, and a uniform paste state can be obtained as a whole.

Eventually, when the particle state changes to a paste state to a certain extent, the upper lump layer _M2 of the glutinous rice M facing inside the fixed ring 21 is also caked and integrated with the lower lump layer _M1 . At such a point, the volume as a whole is condensed, sinks into the lower rotation receiving cylinder 22 and becomes spherical, and is located at the center of the receiving cylinder 22 _. It will be done. Then, as expected, the crushing force of the punch body 11 is effectively applied, as well as the turning action of the fixed blade B, so that the entire area is evenly pumped up. B can be operated without much difference, but it can be carried out more effectively especially by using the fixed blade B shown in the basic example in combination.

[Effect of idea]

As described above, the mochi pounding mortar A of the present invention consists of an assembly of an upper fixed ring 21 and a lower rotating receiving cylinder 22 that communicate concentrically with each other, and has fixed blades B for turning inside. This has the effect of easily solving the problems of the prior art mentioned at the beginning. Moreover, the required structure is extremely simple, and common existing drive means can be used to rotate the lower receiver tube 22, so there is no particular increase in cost, and even more It is of great benefit as it shortens the time required and allows you to obtain high-quality pounded rice cakes.
