Description

[Detailed Description of the Invention] (a) Industrial Application Field The present invention relates to a cooking device for whipping ingredients, particularly for whipping ingredients such as fresh cream, milk, egg yolks and sugar to produce ice cream batter. Regarding a suitable cooking device.

(b) Conventional technology Conventionally, this type of cooking device has a extraction handle extending upward from the center of rotation of the stirring blade, and a scale provided on the side of the handle to measure the whisking height of the material. It is known from Utility Model Publication No. 57-27394.

However, due to the centrifugal force caused by the rotation of the handle, the material is blown to the outer periphery and repeatedly comes into contact with the side surface of the handle, causing the material to pulsate. In addition, since the scale is formed on the side of the handle, it is difficult to see the target, and together with the pulsation of the material, it is difficult to judge whether the material has reached the scale or not. The user had to stop the operation and check the lathering condition based on his/her intuition, and often failed due to excessive lathering.

(c) Problems to be Solved by the Invention The present invention has been made in view of the above-mentioned drawbacks, and an object of the present invention is to provide a cooker that is easy to use and can easily check the whipping state of ingredients without stopping operation. With the goal.

(d) Means for solving the problem The stirring body consists of a stirring blade that rotates close to the inner bottom of the container, and an indicator that projects upward from the center of rotation of the stirring blade, with the upper end having a smaller diameter than the base. The indicator rod is formed at a height such that it is covered by the material when a predetermined amount of the material is foamed to the desired foamed state.

(E) Effect Once formed as described above, when a predetermined amount of material is placed in the container and the agitator is rotated, foaming proceeds while air is mixed in, resulting in volumetric expansion. Then, when the display rod of the stirring body is covered with the material,
This means that the desired foaming state has been achieved.

Before the display rod is covered with material, the material is located at the upper end of the display rod, but
Since the upper end of the indicator rod is formed to have a smaller diameter than the base, the centrifugal force of the indicator rod acts on the material is small. is small, and there is a smooth transition to a state in which the display rod is covered with the material.

When the indicator rod is covered with the material, the centrifugal force of the indicator rod is not applied to the material, so there is no pulsation of the material, and the upper end of the indicator rod is smoothly covered with the material. can be checked at a glance.

(F) Embodiment An embodiment of the present invention will be described in detail below based on the drawings.

Reference numeral 1 denotes a mixer main body containing a built-in electric motor (not shown); 2 a synthetic resin container detachably placed on the main body 1; It is formed into a cylindrical shape, and a rotating shaft 4 is rotatably supported by a bearing 3 provided at the center of the bottom surface. A coupling 5 is fixed to the lower part of the rotating shaft 4 and is detachably engaged with a coupling at the upper end of the output shaft of the electric motor. 6 is the container 2
A cylindrical leg part is formed to hang down from the bottom and is placed on the upper surface of the main body 1. This leg part 6 extends downward from the coupling ring 5, and when the container 2 is placed on a table or the like, the coupling part 5 are prevented from touching tables, etc.

7 is attached to the upper part of the rotating shaft 4,
It is a stirring body made of synthetic resin that rotates at a high speed of about 10,000 rpm to 20,000 rpm, and a disc-shaped stirring blade 8 that is parallel to and close to the inner bottom surface of the container 2 is directed upward from the center of rotation of the stirring blade 8. It is composed of a generally conical display rod 9 that is integrally protruded. The display rod 9 indicates when a predetermined amount of ingredients such as fresh cream, baby milk, egg yolk, sugar, etc. in the container 2 is foamed for "6 to 7 minutes" (volume increase of 1.6 to 2.0 times the initial volume). ,
The upper surface is formed at a height that is covered by approximately the center of the cone-shaped material.

Next, the operation will be explained. The container 2 is placed on the main body 1, and the coupling 5 at the bottom of the rotating shaft 4 is connected to the coupling at the upper end of the output shaft of the electric motor.
Fill the container 2 with ingredients such as fresh cream, milk, egg yolks, sugar, etc. up to the top of the display rod 9, and drive the electric motor to rotate the stirring body 7 at a high speed of about 10.000 rpm to 20.000 rpm. The rotation of the stirring blades 8 causes convection of the material, and air is continuously supplied to the material through the passage indicated by the arrow in FIG. 2A, thereby foaming the material.

At the beginning of operation, the viscosity of the material is low, so the material is blown away by the rotational force of the stirring blade 8, leaving the indicator rod 9 exposed, as shown in FIG. 2A.

As the foaming progresses, the viscosity of the material increases, and as shown in FIG.

As the foaming further progresses, the viscosity of the material increases, and the convection of the material due to the rotational force of the stirring blades 8 is significantly reduced, and as shown in FIG. is covered by the central part of the material. This is the so-called "6-7 minute stand"
This is the optimal state for ice cream dough, which is foamed to 1.6 to 2.0 times the initial volume of the ingredients.

Before the display rod 9 is covered with the material, the material is located at the upper end of the display rod 9, but since the upper end of the display rod 9 is formed to have a smaller diameter than the base, the display The force exerted by the centrifugal force of the rod 9 on the material is small, and therefore, combined with the increased viscosity of the material, the pulsation of the material is small, and the display rod 9
smoothly transitions to a state where it is covered by the material.

When the indicator rod 9 is covered with the material, the centrifugal force of the indicator rod 9 is not applied to the material, so there is no pulsation of the material, and the indicator rod 9 shows that the material is "6".
When the foam reaches the foaming state of ``Steep for ~7 minutes,'' the upper edge is smoothly covered with the material, and it can be confirmed at a glance that it is covered.

In addition, the inner diameter of container 2 is 107 mm, the height of container 2 is 90 mm,
In an experiment, the outer diameter of the stirring blade 8 was 33 mm, the thickness of the stirring blade 8 was 3 mm, the height from the inner bottom of the container 2 to the top of the display rod 9 was 37 mm, and the rotation speed of the stirring body 7 was 12.000 rpm, and the type of fresh cream, etc. The ice cream batter was able to be produced in about 3 minutes, although there were some differences depending on the product. According to this experimental device, when the material is foamed for 6 to 7 minutes, the stirring power decreases significantly.
Even if the agitator 7 is rotated too much, further foaming can be prevented, and there is no problem of the foam decomposing.

Furthermore, it is conceivable to attach an attachment consisting of the container 2, the agitator 7, etc. to the main body dedicated to the juicer or the main body 1' dedicated to the juicer mixer.
Since the height of the coupling provided at the upper end of the output shaft of the motor differs depending on the model, it cannot be used as is. Therefore, as shown in FIG.
A skirt 10 that matches the height of the coupling ring is fixed with screws 12 to a boss 11 formed hanging from the bottom of the container 2, and by replacing the skirt 10 according to the model, the container 2, bearing 3, rotating shaft 4, and stirring body 7 can be easily adjusted. Can be used for multiple models.

(g) Effects of the Invention According to the present invention, it is possible to provide a cooking device that is extremely easy to handle, such as being able to easily determine the whisking state of ingredients without stopping operation.
