For example, the food processors disclosed in Patent Literatures 1 and 2 are capable of chopping and stirring foodstuffs by rotating a blade inside a container.

Japanese Patent Publication No. 59-029255 JP 2018-064760 A

By the way, in this type of device that rotates the blade in the container to cut and stir the ingredients finely, the rotation speed of the blade is slower on the rotation center side than on the centrifugal side. The side is inferior in processing efficiency such as cutting. Especially when processing highly viscous foodstuffs, the movement of the foodstuffs between the rotation center side and the centrifugal side of the blade becomes slow, so relatively delayed foodstuffs tend to stay on the rotation center side. It takes a lot of time to finish processing all the ingredients put into the container.

The present invention has been invented to solve the above problems, and an object of the present invention is to provide a food processor that stirs ingredients while chopping them finely, and which has higher processing efficiency than conventional food processors. It is an object of the present invention to provide a food processor with high processing efficiency especially for highly viscous foodstuffs.

A food processor according to the present invention comprises a rotating shaft arranged in a vertical direction, a rotating blade provided perpendicular to the axis of the rotating shaft and rotating together with the rotating shaft, and a rotating blade provided in the vicinity of the rotating shaft. and a stirring accelerator. The agitation promoting body is connected to the upper surface of the rotary blade, and has an agitation promoting surface in which the lower side is positioned forward in the rotational direction relative to the upper side.

According to the food processor having the matters specifying the invention, the food material on the side of the rotation center is pushed out in the centrifugal direction and obliquely upward by the agitation promoting surface of the agitation promoting body, so that the food material in the container is evenly processed. be.

The food processor comprising the above-mentioned invention specifying matters further comprises a container for containing foodstuffs, and a scraper that slides on the inner side surface of the container, wherein the scraper faces in a direction opposite to the rotation direction of the rotary blade. It is preferable that the

According to the food processor having such invention-specifying matters, the scraper slides in the direction opposite to the direction of rotation of the rotary blade, thereby promoting the agitation of the entire food material in the container.

In the food processor having the items specifying the invention, it is preferable that the scraper has, on the front side in the direction of travel, a slope that slopes toward the side of the direction of travel of the scraper toward the centrifugal side of the rotating shaft.

According to the food processor having such invention-specifying matters, when the scraper moves in the direction opposite to the rotating direction of the rotary blade, the pressing force of the ingredients acts on the slope of the scraper, and the scraper is pressed against the inner side surface of the container by the wedge effect. Therefore, the food material adhering to the inner side surface of the container can be efficiently scraped off. In addition, since the food material on the centrifugal side is pushed toward the center of rotation by the slope of the scraper, the entire food material in the container is stirred.

In the food processor comprising the above-described invention specifying matters, the scraper may slide on the inner side surface of the container while drawing a circular orbit centered on the rotation axis.

According to the food processor provided with such matters specifying the invention, it is possible to make the whole food processor into a compact structure.

According to the present invention, it is possible to provide a food processor with high processing efficiency.

In this embodiment, the rotating shaft 41 is solid, but the shape of the rotating shaft 41 is not limited to this. For example, the shape of the rotating shaft 41 may be hollow.

The rotating blade 42 rotates around the axis N to cut the food into small pieces and stir the food. In this embodiment, the rotary blade 42 is fixed to the lower end of the rotary shaft 41 and rotates together with the rotary shaft 41 . Further, the rotary blade 42 is provided so as to be perpendicular to the axis N. As shown in FIG. In the examples shown in FIGS. 2 and 3, the cutting edge 42a of the rotary blade 42 is curved in the direction opposite to the direction of rotation (the direction indicated by the arrow P1 in FIG. 3) as it goes from the center of rotation to the centrifugal side. ing. Further, the rotary blades 42 extend on both sides of the rotary shaft 41 . In this embodiment, the maximum diameter of the rotary blade 42 is set so that the rotary blade 42 passes under the scraper 5d described later and near the inner side surface 3b of the container 3.

In addition, the agitation promoting surface 43a is connected to the upper surface 42b of the rotary blade 42. As shown in FIG. The inclination angle of the stirring promoting surface 43a with respect to the upper surface 42b of the rotary blade 42 is preferably 10 to 80 degrees, more preferably 60 to 65 degrees.

It should be noted that the relative positional relationship in the rotational direction between the agitation promoting surface 43a and the rotary blade 42 is not limited to that shown in FIG. Also, in the present embodiment, a plurality of (two) agitation promoting bodies 43 are provided, but a single one is also possible.

The agitation promoting body 43 uses its agitation promoting surface 43a to centrifugally and obliquely upwards (in the direction indicated by the arrow P2 in FIGS. 1 and 2) the food material on the rotation center side where the rotation speed of the rotary blade 42 is relatively slow. play a role in sending In particular, since the agitation promoting surface 43a is connected to the upper surface 42b of the rotary blade 42, together with the cutting action of the rotary blade 42, the cut ingredients are efficiently sent out in the centrifugal direction and obliquely upward. This promotes the stirring action within the container 3 .

Further, in this embodiment, as shown in FIG. 3, the agitation promoting surface 43a is formed of a first surface 43a1 and a second surface 43a2. The first surface 43a1 is formed on the rotating shaft 41 side, and the second surface 43a2 is formed continuously on the centrifugal side of the first surface 43a1. The second surface 43a2 is inclined rearward in the rotational direction with respect to the first surface 43a1. As a result, the load on the first motor 61 can be reduced while substantially maintaining the feeding action described above.

In this embodiment, a plate material is used as the agitation promoting body 43, but members other than the plate material can be used as the rotation promoting body 43 as long as the agitation promoting surface 43a can be formed.

The scraping processor 5 is provided to scrape off the food material adhering to the inner side surface 3 b of the container 3 . The scraping unit 5 includes a rotating shaft 5a (hereinafter referred to as "scraping rotating shaft 5a") that rotates around the axis N, and an arm portion 5b that extends in the centrifugal direction from the bottom of the scraping rotating shaft 5a. , a vertical member 5c extending downward from the arm portion 5b, and a scraper 5d fixed to the vertical member 5c. Although a plurality of sets (three sets in this embodiment) of the arm portion 5b, the vertical member 5c and the scraper 5d are provided, a single set is also possible.

The scraping rotary shaft 5a is configured using a hollow shaft. An annular member 5e is fixed to the lower end of the scraping rotary shaft 5a, and the proximal end of the arm portion 5b is fixed to the scraping rotary shaft 5a via the annular member 5e.

The scraper 5d slides on the inner side surface 3b of the container 3 while drawing a circular orbit around the rotating shaft 41 together with the vertical member 5c. As shown in FIG. 2, the sliding direction (moving direction) of the scraper 5 d is opposite to the rotating direction of the rotary blade 42 . In FIG. 2, the solid line arrow indicates the rotation direction of the rotary blade 42, and the broken line arrow indicates the movement direction (rotation direction) of the scraper 5d. In this embodiment, the sliding direction (moving direction) of the scraper 5d is opposite to the rotating direction of the rotary blade 42, but the sliding direction of the scraper 5d is the same as the rotating direction of the rotary blade 42. , the rotation direction of the second motor 62 that operates the scraper 5d may be switchable.

The scraper 5d has an inclined surface 5da on the front side (rotational shaft 41 side) in the direction of travel, which slopes in the direction of travel of the scraper 5d toward the centrifugal side of the rotation shaft 41. As shown in FIG. In this embodiment, the scraper 5d is constructed using a resin plate. When the scraper 5d moves in the direction opposite to the rotating direction of the rotary blade 42, the pressing force of the foodstuff acts on the slope 5da of the scraper 5d, and the scraper 5d is pressed against the inner side surface 3b of the container 3 by the wedge effect. As a result, the food material adhering to the inner side surface 3b of the container 3 is efficiently scraped off. Also, the food on the centrifugal side is pushed toward the rotation center side by the slope 5da of the scraper 5d, and the food on the rotation center side is pushed out to the centrifugal side by the food entering from the centrifugal side to the rotation center side. As a result, the stirring action of the entire food material in the container 3 is promoted.

The base 7 is a stand that supports the container 3 . The base 7 is configured to be vertically movable by a lifting device 8 provided therebelow. The lifting device 8 may be either automatic or manual.

Next, an example of a procedure for processing foodstuffs using the food processor 1 will be described.

First, the lifting device 8 lowers the base 7 to the lowest position, and only the container 3 is taken out from the base 7 . Then, the food material to be processed is put into the container 3, and the container 3 is set on the base 7 again. At this time, the container 3 is fixed at a predetermined position on the base 7 by engaging the engaging portion 3a of the container 3 with the engaged portion 7b. In this embodiment, the predetermined position is a position where the axis N of the rotating shaft 41 and the center line of the container 3 overlap.

Next, the first motor 61 and the second motor 62 are rotationally driven to rotate the rotary blade 42 and the scraper 5d. Subsequently, the lifting device 8 lifts the base 7 to a predetermined height position. The predetermined height position of the base 7 is the position where the rotary blade 42 and the inner bottom surface of the container 3 form a predetermined gap. Here, the predetermined gap varies depending on the type of foodstuff to be processed. For example, when producing rice gel, it is desirable that the predetermined gap is 3.0 mm to 5.0 mm.

The preferred rotation speed of the rotary blade 42 varies depending on the type of food to be processed. For example, when producing rice gel, the rotation speed of the rotary blade 42 is preferably about 1500 rpm to 1700 rpm. Also, the preferred rotation speed of the scraper 5d varies depending on the type of foodstuff to be processed.

When the rotary blade 42 rotates, the food material 9 put into the container 3 is finely cut and agitated. At this time, the food material on the rotation center side is sent out in the centrifugal direction and obliquely upward by the stirring promotion surface 43a of the stirring promotion body 43, so that the food material stays on the rotation center side where the rotation speed of the rotary blade 42 is relatively slow. Therefore, the foodstuffs in the container 3 are evenly processed. As a result, the food can be processed efficiently. In particular, highly viscous foodstuffs (for example, cooked high-amylose rice, which is the raw material of rice gel) tend to stay on the rotation center side, and therefore the processing efficiency is significantly improved by using the food processor 1 according to the present embodiment. improves.
