By the way, if you want to use a food processor to cut the food into small pieces and knead it until it becomes a paste, if the food has an extremely high viscosity, a general food processor on the market may use a motor or a motor. A load may be applied to the rotating parts, which may cause seizure. For this reason, a high torque motor is adopted as a food processor for finely cutting a food material having a high viscosity and kneading it until it becomes a paste, and the load-bearing performance of each rotating portion is enhanced. However, such a food processor has a problem in that it becomes expensive.

Ingredients that exhibit high viscosity include high amylose rice with water added and lotus root rich in mucin. When water is added to high amylose rice and kneaded into a paste by finely cutting it with a food processor or the like, a product called "rice gel" can be produced (see Patent Documents 4 and 5).

The present invention was devised to solve the above-mentioned problems, and reduces a large load applied to a rotating part such as a motor when a food material having high viscosity is cut into small pieces and kneaded until it becomes a paste. The purpose is to provide a food processor that can be used.

The first food processor according to the present invention includes a forward-rotating blade that rotates about an axis in a container and a reverse-rotating blade that rotates in a container in a direction different from that of the forward-rotating blade in a coaxial line. Both the forward rotary blade and the reverse rotary blade are formed parallel to the plane orthogonal to the axis line, and the shape of the cutting edge is curved in the direction opposite to the rotation direction from the rotation center side to the rotation centrifugal side. Is.

According to the food processor provided with the above-mentioned item specifying the invention, the shapes of the cutting edges of the forward-rotating blade and the reverse-rotating blade that rotate in different directions are curved in the direction opposite to the rotation direction from the rotation center side to the rotation centrifugal side. Therefore, it is possible to perform "pulling" to cut the food while moving the cutting edge in the blade crossing direction with respect to the food. Due to the effect of this "pulling off", the rotary blade cuts the food into small pieces, and the reaction force in the rotation direction received from the food when kneading the food is reduced, and the load on the rotating parts such as the motor and the rotary power branch mechanism is reduced. It gets smaller.

The hood processor according to the second aspect of the present invention has a plurality of positive rotation blades that rotate around different axes in the same container, and a plurality of forward rotation blades that rotate in the same container in different directions in coaxial lines. It is equipped with a plurality of reverse rotary blades. Both the forward rotary blade and the reverse rotary blade are formed parallel to the plane orthogonal to the axis line, and the shape of the cutting edge is curved in the direction opposite to the rotation direction from the rotation center side to the rotation centrifugal side. Is.

According to the food processor provided with the above-mentioned matters specifying the invention, the effect of the above-mentioned "pull-off" can be obtained, and the processing capacity can be improved by providing a plurality of forward-rotating blades and reverse-rotating blades.

In the hood processor according to the second aspect of the present invention, at least one of the plurality of forward rotation blades and the plurality of reverse rotation blades, the forward rotation blade and the reverse rotation blade rotating around the coaxial line thereof are the other. It is desirable to rotate at a different rotation speed than the forward and reverse rotation blades.

According to the food processor provided with the above-mentioned invention-specific matters, it is possible to form a flow of the foodstuff that has been shredded or pasted over the entire container, and the foodstuff in the container is evenly shredded or pasted. can do.

It is desirable that the food processor according to the second aspect of the present invention is provided with a rotation speed adjusting means capable of individually adjusting the rotation speeds of the plurality of forward rotation blades and the plurality of reverse rotation blades.

According to the food processor provided with the above-mentioned matters specifying the invention, the rotation speed of the rotary blade is appropriately adjusted for each axis to form a flow of shredded or pasted foodstuffs throughout the container. The foodstuffs in the container can be evenly shredded or made into pastes.

In any of the above food processors, a plurality of protrusions may be formed on one or both of the surfaces of the forward rotating blade and the reverse rotating blade facing each other.

According to the food processor provided with the above-mentioned matters specifying the invention, the formation of the protrusion makes it difficult for the food material to come into close contact with the facing surface, and it is possible to reduce the load on the rotating portion such as the motor and the rotary power branching mechanism.

According to the present invention, for example, even when a food material having a high viscosity is cut into small pieces and kneaded until it becomes a paste, a large load applied to the rotating portion can be reduced.

It is a top view which shows the main part of the food processor which concerns on the modification of embodiment of this invention.

Hereinafter, the food processor according to the embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 and 2, the food processor 1 according to the embodiment of the present invention includes a container 2, a forward rotary blade 3, a reverse rotary blade 4, a rotary drive device 5, and the like.

As shown in FIGS. 1 and 2, the container 2 is composed of a container body 2a and a lid 2b. The container body 2a is mainly composed of a cylindrical side wall portion 2ab, an annular bottom plate portion 2ac, and an inner cylinder portion 2ad that rises cylindrically upward from the opening edge of the bottom plate portion 2ac. The container 2 is installed on the base 7.

The forward rotary blade 3 and the reverse rotary blade 4 rotate in the container 2 around the same axis N in different directions. As shown in FIG. 2, the forward rotary blade 3 and the reverse rotary blade 4 each have a shape in which the shapes of the cutting edges 3a and 4a are curved in the direction opposite to the rotation direction from the rotation center side to the rotation centrifugal side. .. In the rotary blades 3 and 4 illustrated in FIG. 2, the shapes of the cutting edges 3a and 4a are formed in a substantially arc shape, and further, a saw blade is formed on the cutting edges 3a and 4a. Further, a plurality of forward rotary blades 3 and reverse rotary blades 4 are provided at equal intervals in the rotation direction (two blades each in the example of FIG. 2). Further, the forward rotary blade 3 and the reverse rotary blade 4 are formed parallel to the plane orthogonal to the axis N, and their axial gap B (vertical gap in FIG. 1) is a small gap (for example, about 3 to 7 mm). The gap, preferably about 5 mm). In FIGS. 2 and 3, reference numeral 3R indicates a rotation direction of the forward rotary blade 3, and reference numeral 4R indicates a rotation direction of the reverse rotary blade. Further, the maximum radius r1 of the rotary blades 3 and 4 is set to a value slightly smaller than the inner radius r2 of the container body 2a (for example, about -3 to 7 mm, preferably about 5 mm).

The forward rotary blade 3 is provided integrally with the bottomed cylindrical outer rotary cylinder 8. The reverse rotary blade 4 is provided integrally with the bottomed cylindrical inner rotary cylinder 9 arranged in the outer rotary cylinder 8 so as to be relatively rotatable. As shown in FIG. 1, the distance between the outer rotary cylinder 8 and the forward rotary blade 3 and the inner rotary cylinder 9 and the reverse rotary blade 4 is provided at the inner lower end portion of the outer rotary cylinder 8 and the outer lower end portion of the inner rotary cylinder 9. A bush 16 having an L-shaped cross section for maintaining a constant position is fitted.

The rotary drive device 5 includes a motor 10, an inverter 11, a rotary power branch mechanism 12 that splits the rotational power of the motor 10 into two hands, a double shaft 13, and the like.

The motor 10 is rotationally driven by power supply from the inverter 11 and rotationally drives the inner shaft 13a and the outer shaft 13b of the double shaft 13 via the rotational power branch mechanism 12. The inverter 11 serves as a means for adjusting the rotation speed of the motor 10, and makes it possible to adjust the rotation speed of the motor 10 to a desired value. Of course, as the rotation speed adjusting means of the motor 10, a device other than the inverter 11 may be applied. Further, although not shown, the food processor 1 is also provided with a rotation speed meter for checking the rotation speed of the motor 10. In the present embodiment, the rotational power branching mechanism is constructed so that the rotational speed of the motor 10, the rotational speed of the forward rotary blade 3, and the rotational speed of the reverse rotary blade 4 are equal. Therefore, the rotation speeds of the rotary blades 3 and 4 can also be confirmed by the rotation speed meter of the motor 10.

Although not described in detail, the rotary power branching mechanism 12 can be constructed by, for example, various gears, known parts such as endless belts, and members.

The double shaft 13 is composed of an inner shaft 13a and an outer shaft arranged so as to be relatively rotatable inside and outside each other. The inner shaft 13a penetrates the outer shaft, and the upper end thereof is rotationally and integrally connected to the outer rotary cylinder 8. The upper end of the outer shaft 13b is rotationally and integrally connected to the inner rotary cylinder 9. Further, the outer shaft 13b is supported by the base 7 via the bearing 15.

The upper end portion of the inner shaft 13a has an enlarged diameter, and the upper end edge of the inner cylinder portion 2ad of the container 2 is arranged near the lower surface thereof via a minute gap. Since the gap between the lower surface of the upper end portion of the inner shaft 13a and the upper end edge of the inner cylinder portion 2ad is a minute size in this way, the material finely cut in the container 2 gets over the inner cylinder portion 2ad and passes over the inner cylinder portion 2ad. It is prevented from getting inside. The gap between the base 7 and the outer peripheral surface of the outer shaft 13b is sealed with an oil seal 14.

When processing foodstuffs using the above food processor 1, first, the foodstuffs are put into the container 2, the lid 2b is closed, and the motor 10 is rotated. The rotation speed of the motor 10 is set by the inverter 11 to a value suitable for the food material to be processed. For example, when high amylose rice and a predetermined amount of water are put into the container 2 in order to make "rice gel", the rotation speed of the rotary blades 3 and 4 may be about 1500 to 1700 rpm. It should be noted that this rotation speed is an example, and the optimum rotation speed may be other than the above rotation speed.

According to the hood processor 1 according to the embodiment of the present invention, the shapes of the cutting edges 3a and 4a of the forward rotary blade 3 and the reverse rotary blade 4 that rotate in different directions change from the rotation center side to the rotation centrifugal side. Since it is curved in the opposite direction, it is possible to perform "pulling" to cut the food while moving the cutting edges 3a and 4a in the blade crossing direction with respect to the food. Due to the effect of this "pulling", the rotary blades 3 and 4 can cut the food into small pieces and reduce the reaction force in the rotational direction received from the food when kneading the food, so that the food develops high viscosity. Even if it is, it is possible to suppress the load on the rotating portion of the motor 10, the rotary power branching mechanism 12, and the like. In the food processor (mixer) disclosed in Cited Documents 1 to 3, the cutting edge is not curved with respect to the rotation direction of the rotating blade when viewed from above, but the food material is cut by so-called "push-cutting". Therefore, the above-mentioned action and effect of the present invention cannot be obtained.

Further, according to the food processor 1 according to the embodiment of the present invention, since the rotary blades 3 and 4 rotate in different directions, the food material develops high viscosity and adheres to the rotary blades 3 and 4. Even if it is easy (rice gel, etc.), there is little possibility that the foodstuff will rotate with the rotary blades 3 and 4 and the processing efficiency will decrease.

4 (a) to 4 (f) show how the forward rotary blade 3 rotates counterclockwise and the reverse rotary blade 4 gradually rotates clockwise when viewed from above. First, as shown in FIGS. 4 (b) to 4 (d), the foodstuff in the shaded area of FIG. 4 (a) is cut while being sandwiched between the forward rotary blade 3 and the reverse rotary blade 4 whose intervals are gradually narrowed. After that, the foodstuffs in the shaded areas of FIGS. 4 (e) and 4 (f) are cut. By frequently moving the place where the food is cut in this way, the food in the container 2 is processed evenly. Further, when the absolute values of the rotation speeds of the forward rotary blade 3 and the reverse rotary blade 4 are set to different values, the region surrounded by the cutting edges 3a and 3b gradually moves, so that the foodstuffs in the container 2 are evenly distributed. It will be easier to process.

− Modifications of the embodiment 1-
In the above embodiment, a large number of protrusions may be formed on one or both of the surfaces of the forward rotary blade 3 and the reverse rotary blade 4 facing each other. 5 and 6 show an example in which a large number of protrusions 17 are formed on both the surfaces of the forward rotary blade 3 and the reverse rotary blade 4 facing each other. Foodstuffs tend to adhere to the facing surfaces 3b and 4b of the forward rotating blade 3 and the reverse rotating blade 4, but by forming the protrusions 17 in this way, the contacting of the foodstuffs to the facing surfaces 3b and 4b is suppressed. , The load on the rotating parts of the motor 10, the rotary power branching mechanism 12, and the like can be reduced. The protrusion 17 shown in FIGS. 5 and 6 has a conical shape, but the shape of the protrusion 17 is not limited to this.

− Modifications of the embodiment 2-
In any of the above embodiments, the container body 2a is cylindrical, but the inner surface of the container body may be mortar-shaped. In this case, it is expected that the foodstuffs are less likely to adhere to the wall surface inside the container, and the foodstuffs in the container can be processed evenly.

− Modification of the embodiment 3-
In any of the above embodiments, as shown in FIG. 7, a plurality of the above-mentioned forward rotary blades 3, reverse rotary blades 4, rotary drive devices 5 and the like are provided in one container 2A (4 in FIG. 7). It may be the provided food processor 1A. As a result, the processing capacity can be improved. As the container 2A, a container 2A having the same shape as the container 2 and having a large size can be used. However, the inner cylinder portion 2ad of the container 2 is formed for each pair of rotary blades 3 and 4. It is desirable that the distance between the axial positions of the rotary blades 3 and 4 is evenly provided in the container 2 in the circumferential direction. Hereinafter, a pair of rotary blades 3 and 4 that rotate around the same axis will be described as a set of rotary blades.

In the food processor 1A, at least one set of the rotary blades 3 and 4 among the four sets of rotary blades 3 and 4 may rotate at a rotation speed different from that of the other sets of rotary blades 3 and 4. Preferably, all sets of rotary blades 3 and 4 rotate at different rotational speeds from each other. For example, it is conceivable to sequentially reduce the rotation speed clockwise or counterclockwise when viewed from above. Specifically, as shown in FIG. 7, the rotation speeds of the rotary blades 3 and 4 of the first set M1 are 1500 rpm, the rotational speeds of the rotary blades 3 and 4 of the second set M2 are 1400 rpm, and the rotary blades 3 of the third set M3. It is conceivable that the rotation speed of, 4 is 1300 rpm and the rotation speed of the rotary blades 3 and 4 of the fourth set M4 is 1200 rpm. By making the rotation speeds of the rotary blades 3 and 4 of each set different in this way, it is possible to form a flow of the shredded or pasted food material over the entire container 2A, and the food material in the container 2A can be formed. Can be processed evenly.

Further, in the present embodiment, by providing the motor 10 and the inverter 11 for each set, the rotation speeds of the rotary blades 3 and 4 of each set can be individually adjusted. By appropriately adjusting the rotation speeds of the rotary blades 3 and 4 of each set as appropriate, it is possible to form a more suitable flow of the shredded or pasted food material over the entire container 2A, and the container 2A can be formed. It is possible to process the ingredients inside evenly.

In the embodiment according to the above modification, the rotation speeds of the rotary blades 3 and 4 are different or adjustable for each set, but further, the absolute value of the rotation speeds of the rotary blades 3 and 4 of the same set is used. The rotation speed may be different, or the rotation speed adjusting means may be provided so that the rotation speed can be adjusted separately for each of the same set of rotary blades 3 and 4.

The present invention is applicable to a food processor that finely cuts foodstuffs with a rotary blade.
