Description

  The present invention relates to an agitating and foaming apparatus capable of containing fine bubbles by stirring and foaming frozen foods such as ice cream.

  In general, in frozen foods such as ice cream and soft cream, not only the ingredients are mixed, but also bubbles are entrained in the material to cause foaming (so-called whipping). In such foodstuffs, a delicious flavor is obtained by drawing out the difference in texture depending on the size of the bubbles contained. In particular, a soft texture is obtained by whipping fine bubbles called microbubbles into the material.

Conventionally, as a device that mixes and stirs foodstuffs, a foodstuff container containing foodstuffs is rotated by driving a stirring stirrer or a rotating blade attached to the tip of a rotating shaft to rotate the foodstuffs. A stirring mixer is used (for example, see Patent Document 1).
In such a mixer, not only mixing but also bubbles are included in the material by stirring the food with a movable stirrer or a rotating blade.

JP 2006-61583 A

In the above conventional technique, the following problems remain.
That is, in the conventional apparatus for stirring and foaming materials, the movable stirrer and the rotating blade are rotated in the material. Therefore, when the material to be treated is frozen food such as ice having a high viscosity, it takes time for stirring and foaming. There was a problem that it took. Further, even when the movable stirrer and the rotary blade are rotated at high speed in the material, the generated bubbles are rough and it is difficult to obtain sufficiently fine microbubbles. Furthermore, when the movable stirrer and the rotating blade are damaged, there is a possibility that foreign substances may be mixed in the food, and there is a demand for a method other than the stirring / foaming method in which the movable stirrer and the rotating blade are rotated in the container. . Further, when the movable stirrer and the rotating blade are deteriorated, the stirring / foaming ability is lowered, and it is necessary to clean the movable stirrer and the rotating blade after use.

  The present invention has been made in view of the above-described conventional problems, and provides a stirring and foaming apparatus capable of foaming microbubbles in a short time even with a high viscosity material without using a movable stirrer or a rotating blade. With the goal.

  The present invention employs the following configuration in order to solve the above problems. That is, the stirring and foaming device according to the first aspect of the invention includes a revolution body that can rotate around a revolution axis, a rotation body that is held by the revolution body and that can rotate around a rotation axis, the revolution body, and the A driving mechanism that rotationally drives the rotating body; and a container that is attached to the rotating body and stores a material to be processed, wherein the driving mechanism rotates the rotating body at a higher rotational speed than the revolution body, The container has a plurality of protrusions on the inner peripheral surface.

In this stirring and foaming device, the drive mechanism rotates the rotating body at a higher rotational speed than the revolution body, and the container has a plurality of protrusions on the inner peripheral surface, so material convection by centrifugal force, Due to the stirring effect of the plurality of protrusions in the container that rotates at a higher rotational speed than the revolution speed of the revolution body, the material to be processed is efficiently stirred and contains a sufficiently large number of microbubbles. It becomes possible to foam and whip. In particular, even a highly viscous material to be processed can be whipped in a short time by a protrusion in a container that revolves and rotates at high speed. Furthermore, since no movable stirrer or rotating blades are used, it is possible to prevent foreign matters from being mixed due to these damages. Also, if the container is made disposable, maintenance of the apparatus such as cleaning becomes easy.
In addition, when the rotation speed of the autorotation body is lower than that of the revolution body, the bubbles are not sufficiently miniaturized, and the bubbles become rough and it is difficult to obtain fine microbubbles. That is, in the present invention, since the revolution number of the revolution body is lower than the revolution number of the rotation body, the defoaming effect by the revolution energy is reduced, and the foaming effect by the rotation energy becomes dominant and the microbubbles are easily formed. . In particular, the protrusions that rotate at high speed collide with the material to be processed to entrain the bubbles and miniaturize them, so that many microbubbles can be efficiently contained.

The stirring and foaming device according to a second invention is characterized in that, in the first invention, the protrusions are a plurality of protrusions extending along the rotation axis.
That is, in this stirring and foaming apparatus, since the protrusions are a plurality of protrusions extending along the rotation axis, the object to be processed is offset to the inner peripheral surface of the container by centrifugal force in the container that rotates and rotates. By effectively stirring the ridges extending the material, it becomes possible to contain more fine bubbles.

The stirring and foaming device according to a third invention is characterized in that, in the first or second invention, the rotation axis is inclined with respect to the revolution axis with the upper portion of the container facing inward. .
That is, in this stirring and foaming apparatus, since the rotation axis is inclined with respect to the revolution axis with the upper part of the container facing inward, the material to be treated in the container is outside the revolution axis, and centrifugal force due to revolution is generated. Thus, even if the material to be processed is shifted to the outside, it can be prevented from jumping out of the container.

The stirring and foaming device according to a fourth invention is the stirring and foaming device according to the third invention, wherein the drive mechanism is connected to one drive source having a rotary shaft and the rotary shaft of the drive source, and the rotational force of the drive source is And a power transmission mechanism for simultaneously transmitting to the revolution body and the rotation body, wherein the rotation axis is inclined 5 to 15 ° inward with respect to the revolution axis.
That is, in this stirring foaming device, the rotation axis is inclined 5 to 15 ° inward with respect to the revolution axis, so that the rotation body and the container are inclined at a relatively shallow angle, so that even one drive source can The revolution body can be simultaneously driven faster than the rotation body, and the apparatus cost can be suppressed. In addition, when the inclination of the rotation axis exceeds 15 °, energy loss due to the inclination of the rotation body is large, and it is difficult to simultaneously perform rotation at a speed faster than revolution with one drive source. Moreover, when the inclination of the rotation axis is less than 5 °, the container, the support member, and the like may be bent by the centrifugal force and the container may jump out.

The stirring and foaming apparatus according to a fifth invention is characterized in that, in any of the first to fourth inventions, the material to be treated is a frozen food.
That is, in this stirring and foaming apparatus, since the material to be treated is a frozen food, it is possible to sufficiently stir the high-viscosity frozen food, and it can be easily whipped by the foaming of microbubbles. . Even in the case of a low-viscosity material, it can be processed in a shorter time than before due to a high stirring force.

The present invention has the following effects.
That is, according to the stirring and foaming device of the present invention, the drive mechanism rotates the rotating body at a higher rotational speed than the revolving body, and the container has a plurality of protrusions on the inner peripheral surface. Microbubbles can be generated in a short time even with a material having a high viscosity without using a stirrer or a rotating blade.
Therefore, the stirring and foaming device of the present invention is suitable for stirring and foaming of high-viscosity frozen foods, etc., especially by making ice cream into soft cream, pasting fruits such as strawberries, and mixing ice with matcha powder. Suitable for whipping and pasting various materials such as matcha ice cream.

Yes. Since the rotational energy is proportional to the square of the rotational speed, when the rotational speed is doubled, the rotational energy is quadrupled.

The container 5 is a bottomed cylindrical container having a tapered cross section in which the inner diameter of the upper opening is set slightly larger than the bottom, and is made of plastic or the like.

The rotation axis L2 is inclined with respect to the revolution axis L1 with the upper portion of the container 5 facing inward. That is, the rotation axis L2 is inclined at an angle θ toward the inner revolution axis L1 that is the vertical axis.
The rotation axis L2 is preferably inclined at an angle θ of 5 to 15 ° inward with respect to the revolution axis L1. In the present embodiment, for example, the rotation axis L2 is inclined 10 ° inward with respect to the revolution axis L1.
When the rotation axis L2 is inclined at an angle exceeding 15 °, in order to set the rotation speed to twice the rotation speed, a drive source with high rotational energy is used for rotation. It is necessary to provide it separately.

The drive mechanism 4 includes a single drive source 10 having a rotation shaft 10 a and a power transmission mechanism 9 that is connected to the rotation shaft 10 a of the drive source 10 and simultaneously transmits the rotational force of the drive source 10 to the revolution body 2 and the rotation body 3. And.
The drive source 10 is a motor or the like, and a first pulley 10b is fixed to the rotary shaft 10a.

The drive source 10 is fixed to the lower surface of the main body base 11, and the rotation shaft 10 a is inserted into the rotation shaft hole 11 a formed in the main body base 11 and protrudes from the upper surface side of the main body base 11.
The revolution body 2 as a rotation unit is supported so as to be rotatable around a revolution shaft portion 11 a provided upright on the main body base 11. The revolution shaft portion 11a is fixed coaxially with the revolution axis L1.

The revolution body 2 includes a pair of rotating arms 12 extending outward in the radial direction, and a second pulley 12 a for revolution fixed to the lower part of the pair of rotating arms 12.
A revolution belt 13 is wound around the first pulley 10b and the second pulley 12a, and the driving force of the drive source 10 is transmitted from the first pulley 10b to the second pulley 12a via the revolution belt 13. The revolution body 2 is driven to rotate. That is, the first pulley 10 b, the revolution belt 13, and the second pulley 12 a constitute a part of the power transmission mechanism 9.

A rotation shaft 12 that is coaxial with the rotation axis L <b> 2 is erected at the tip of the rotation arm 12, and the rotation body 3 is rotatably provided on the rotation shaft 14.
The rotating body 3 includes a container holder H that can rotate around a rotating shaft portion 14 via a rotating bearing 15, and a rotating gear 16 that is provided on a lower outer peripheral portion of the container holder H around a rotating axis L <b> 2. And.

The rotation bearing 15 is provided between the rotation shaft portion 14 and the rotation gear 16. In other words, the rotation gear 16 and the container holder H are rotatably supported with respect to the rotation shaft portion 14 via the rotation bearing 15.
The rotation shaft portion 14 coaxial with the rotation axis L2 is inclined in a range of 5 to 10 ° toward the inside at a predetermined angle with respect to the revolution axis L1, and is inclined at 10 ° in this embodiment.
The said container holder H is formed in the bottomed cylinder shape with a hard material, and the container 5 can be installed in the inside.

A rotation miter gear 17 is fixed to the tip end portion of the revolution shaft portion 11a, and teeth formed on the outer peripheral portion mesh with the pair of rotation gears 16, respectively. That is, when the rotary arm 12 rotates, the rotation gear 16 meshed with the rotation miter gear 17 rotates, and the rotation body 2 rotates. Therefore, the bearing 15 for rotation and the miter gear 17 for rotation constitute a part of the power transmission mechanism 9.

  Next, the stirring / foaming method of the material M to be processed by the stirring foaming device 1 of the present embodiment will be described.

First, a predetermined amount of material M to be processed such as ice is put in the container 5, and the container 5 is set in the container holder H.
When the drive source 10 is driven in this state to rotate the rotary shaft 10a, the revolution body 2 revolves around the revolution shaft portion 11a via the first pulley 10b, the revolution belt 13, and the second pulley 12a. At this time, since the rotation gear 16 meshes with the revolving shaft portion 11 a that does not rotate, the rotation gear 16, the container holder H, and the container 5 rotate through the rotation bearing 15. In this embodiment, for example, when the revolution is clockwise, the rotation is counterclockwise.

In addition, each gear is set so that the rotation speed of rotation and revolution is “rotation speed: revolution speed = 2: 1”, and the rotation speed is 2000 rpm. The number is 1000 rpm.
Centrifugal force is applied to the material to be processed M in the container 5 by the above revolution, and the material to be processed M in the container 5 is stirred by the rotation. At this time, since the protrusion 5a is formed on the inner peripheral surface of the container 5, the material M to be processed is agitated by the protrusion 5a, and the bubbles are refined to generate microbubbles, which are whipped.

  Thus, in the stirring and foaming device 1 of the present embodiment, the drive mechanism 4 rotates the rotating body 3 at a higher rotational speed than the revolution body 2, and the container 5 has a plurality of protrusions 5a on the inner peripheral surface. Therefore, the material M to be processed is efficiently obtained by the material convection due to the centrifugal force and the mixing effect by the plurality of protrusions 5a in the container 5 that rotates at a higher rotational speed than the rotational speed of the revolution body 2. While stirring, a large amount of sufficiently fine microbubbles can be contained to be foamed and whipped.

Even if the material M to be processed has a high viscosity, it can be whipped in a short time by the protrusion 5a in the container 5 that revolves and rotates at high speed.
In particular, by using the processed material M as a frozen food, it is possible to sufficiently stir the high-viscosity frozen food, and it can be easily whipped by microbubbles.
Furthermore, since no movable stirrer or rotating blades are used, it is possible to prevent foreign matters from being mixed due to these damages. Further, if the container 5 is made disposable, maintenance of the apparatus such as cleaning becomes easy.

  In addition, when the rotation speed of the autorotation body 3 is lower than the revolution body 2, the refinement | miniaturization of the bubble by autorotation will become inadequate, a bubble will become coarse and it will become difficult to obtain a fine microbubble. That is, in this embodiment, since the rotation speed of the revolution body 2 is lower than the rotation speed of the autorotation body 3, the defoaming effect by revolution energy becomes small, the foaming effect by autorotation energy becomes dominant, and a microbubble is formed. It becomes easy to do. In particular, the protrusion 5a that rotates at a high speed collides with the material M to be processed and entrains the bubbles and miniaturizes them, so that it is possible to efficiently contain many microbubbles.

Moreover, since the protrusion part 5a is a some protrusion part extended along the autorotation axis L2, the to-be-processed material M which shifted to the internal peripheral surface of the container 5 with the centrifugal force in the container 5 to revolve and rotate is made. It becomes possible to contain more fine bubbles because the extending protrusions are effectively stirred.
In addition, since the rotation axis L2 is inclined with respect to the revolution axis L1 with the upper portion of the container 5 facing inward, it is possible to prevent the material M to jump out of the container 5 even if the processing material M is offset to the outside due to centrifugal force due to revolution. can do.

  Further, since the rotation axis L2 is inclined 5 to 15 ° inward with respect to the revolution axis L1, the rotation body 3 and the container 5 are inclined at a relatively shallow angle, so that even one drive source 10 can rotate the revolution body. 2 can be driven simultaneously faster than the rotating body 3, and the cost of the apparatus can be suppressed.

In addition, this invention is not limited to the said embodiment, A various change can be added in the range which does not deviate from the meaning of this invention.
For example, the material to be treated is not limited to frozen foods such as the above-mentioned ice cream (frozen confectionery), but is also suitable for various high-viscosity raw materials for obtaining purees and pastes. Vegetables, fish, meat, confectionery, jams, dairy products, beverages, and the like can also be used as a target for stirring and foaming.
