Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stirring device for foods, and particularly to a stirring device for stirring highly viscous foods.

A conventional food stirring blade is composed of a pair of blades.

The pair of blades are made symmetrically with respect to the stirring axis, and are therefore relatively long.

Containers containing stirred foods are usually standard products, but they are made of relatively thin stainless steel or copper plates, so it is impossible to prevent temporary or permanent distortion during manufacture or use. .

Because of the distortion, the stirring blades cannot slide in close contact with the inner surface of the container.

Furthermore, because conventional stirring blades are relatively long, even the slightest distortion of the container causes them to rise from the inner surface of the container.

Food tends to stick to areas where the wings can't slide while remaining in perfect contact with each other, and these areas become scorched.

Even if there is only a slight amount of charring at first, once charring occurs, the amount of charring will gradually increase.

When charred food is mixed into food, the quality of the food deteriorates significantly.

In order to prevent this kind of burning, the fire power is turned down once the viscosity of the food reaches a certain level and the fire power is carefully adjusted, but this ultimately reduces thermal efficiency. Moreover, it requires special skill and constant monitoring, and is not economical or workable.

Further, the stirring blade is screwed to the stirring shaft or blade mounting plate to which it is fixed.

The small gap between the wing and the fixed wing makes it impossible to completely clean or sterilize it in daily operations.

These gaps become nests for bacteria, especially cocci, and cause food contamination.

An object of the present invention is to provide an economical food stirring device that has good thermal efficiency and does not consume wasteful thermal energy.

Another object of the present invention is to provide a clean food stirring device.

Still another object of the present invention is to provide a food stirring device that allows easy attachment and detachment of parts and is easy to handle.

Still another object of the present invention is to provide a stirring device with high operability that quickly supplies a desired food product.

The present invention will be described in detail below based on embodiments and with reference to the drawings.

As shown in FIGS. 1 and 2, a stirring device 1 of the present invention
are the stirring shaft 2, the stirring shaft layer horizontal rotary plate 21, the stirring blade 22 attached to the lower end of the stirring shaft, the scraper shaft 3, the scraper shaft layer horizontal rotating plate 31, and the scraper shaft layer horizontal rotating plate 31 attached to the lower end of the scraper shaft. It has a scraper 32.

The stirring shaft layer rotating plate 21 integrally fixes the upper end of the stirring shaft, and rotates the center line 1 of the container 10 through stirring shaft rotation means (not shown).
Rotate around 1 as the center of rotation.

The scraper shaft rotating plate 31 connects the upper part of the scraper shaft 3 and rotates about the center line 11 of the container 10 through scraper shaft rotation means (not shown).

These rotating plates 21.31 are arranged concentrically, and both rotating plates 21.31 rotate in opposite directions.

Food to be stirred by the stirring device 1 is stored in a container 10.

The stirring shaft 2 is displaced by a predetermined angle θ with respect to the rotation center 11 of the rotary plate 21 (center line of the container 10).

A stirring blade reinforcing plate 221 integrally formed with the stirring shaft 2 is provided at the lower end of the stirring shaft 2, as shown in FIG. 3a.

This reinforcing plate 221 has a protrusion 222 near the extension of the stirring shaft 2.
has.

The reinforcing plate 221 further has a stopper 2 on the upper end surface of its base.
It has 23.

Both the protrusion 222 and the stopper 223 are each provided integrally with the reinforcing plate 221 by, for example, welding.

This catch 223 fits the upper end surface 224 of the stirring blade 22 and locks the stirring blade 22 downward.

Therefore, when the stirring blade 22 presses the container 10 through the food to be stirred, the stress of the container 10 or the stirring blade 22 serves to suppress the stirring blade from springing up.

The stirring shaft 2 also consists of an upper shaft 23 and a lower shaft 24.

The upper end of the upper shaft 23 is fixed to the rotating plate 21.

The upper shaft 23 and the lower shaft 24 are joined together by inserting the upper part 240 of the lower shaft 24 into the upper shaft hollow 230 from the lower open end 231 and inserting the locking tool 2415 of the lower shaft 24, such as a stopper. This can be easily carried out by engaging a cutout groove 232 provided near the open end 231 of the upper shaft, for example, an inverted-shaped groove.

By allowing the locking tool 241 to freely move in the groove 232 in the axial direction of the stirring shaft 2, the stirring blade 22 at the lower end of the stirring shaft can easily cope with even the slightest distortion of the inner wall of the container 10, and remains in close contact with the inner wall of the container from beginning to end. It can move.

The agitating blade 22 has the protrusion 222 fitted into the hole 220 near its base, and the upper end surface 224 of the agitating blade 22 is connected to the stopper 22.
3, it can be aligned and fixed to the surface of the reinforcing plate 221.

Then, while pressing the vicinity of the bottom of the container 10, it rotates around the stirring shaft 2 as the rotation plate 21 rotates and revolves around the rotation plate rotation center 11.

The stirring blade 22 is composed of a single blade, as shown in FIG.

This blade is made to extend longer in the direction of shaft displacement with respect to the stirring shaft 2.

This blade can be attached to the reinforcing plate 2 without using other members such as screws.
21, the attachment/detachment operation is extremely easy.

Therefore, it can be completely cleaned after use and can always be kept in a clean state.

The scraper shaft 3 is rotatably engaged with a scraper shaft piece rotary plate 31 at its upper portion.

A scraper reinforcing plate 331 is provided at the lower end of the scraper shaft 3 and integrally formed with the shaft 3.

Similar to the stirring blade reinforcing plate 221, this reinforcing plate 331 has a protrusion 333 integrally provided near the extension line of the scraper shaft 3 by means such as welding.

This reinforcing plate 331 further includes the stirring blade reinforcing plate 221.
Similarly, a catch 334 is integrally provided.

This reinforcing plate 334 also connects the upper end of the scraper 32 to the container 1.
When the scraper 32 presses the container 10 through the food, it acts to suppress the scraper from springing up due to stress in the container or the scraper.

The scraper shaft 3 has a scraper mounting shaft 33 curved downward at its upper end.

This mounting shaft 33 is fitted into a scraper mounting shaft holding hole 310 at one end of the rotary plate 31.

Therefore, the scraper shaft 3 has a mounting shaft 33 and a holding hole 31.
0, it can freely rotate about the center line 30.

A stopper 311 is provided near the holding hole 310, and the stopper 311 locks the engagement protrusion 34 of the scraper mounting shaft 33 at a predetermined position.

Therefore, the free rotation of the scraper shaft 3 is restricted to a predetermined angle.

The length of the scraper shaft is the rotation shaft center 11 of the rotary plate 31.
A vertical plane passing through a line 300 from 1 (rotation center 11 of the rotor plate 21) to the rotation center 301 of the engaging portion is predetermined along the rotation direction of the rotor plate 31 around the rotation axis center 111 of the rotor plate 31. The scraper 32 is selected to be located at a position 302 where this vertical plane intersects the inner circumferential wall of the container when rotated by an angle α, for example, about 20° to about 30°.

That is, in FIG. 2, the line segment connecting points 301 and 302 is longer than the line segment connecting points 301 and 303.

Therefore, the scraper shaft, which has a length corresponding to the distance between points 301 and 302, slides the scraper 32 at its lower end on the inner wall of the container and rotates in the direction of arrow B to push away the food. 32 receives a reaction from the pressed food and receives stress in the direction opposite to the direction of arrow B.

As the point 302 moves in the direction 303 along the periphery of the container, the distance from the point 301 becomes shorter.

Therefore, the scraper shaft 3 is bent against B due to the stress from the food.
The more the scraper 32 is pushed back in the direction of the arrow, the more the scraper 32 is pressed against the inner wall of the container 10 and comes into close contact with it.

Similar to the stirring blade 22, the scraper 32 is aligned and fixed to the surface of the scraper reinforcing plate 331 by fitting a protrusion 333 into a hole (not shown) near its base and fitting its upper end surface into a clasp 334. be done.

The scraper 32 has a protrusion 333 and a stopper 334 like this.
Although it is fixed to the reinforcing plate 331, it is fixed so as to be slightly movable.

Therefore, as mentioned above, the stress of the food pushes the scraper back in the direction opposite to the direction of arrow B, causing the inner wall of the container to
Even if it comes into close contact with zero, its fine movement allows it to respond to slight distortions of the inner wall of the container with high precision.

As a result, an ideal pulling function can be exerted on the inner wall 10 of the container.

In this manner, the scraper 32 rotates around the rotary plate rotation center 11 as the rotary plate 31 rotates while scraping off food adhering to the inner wall of the container 10 into the container.

This scraper consists of a single blade. The blades are shaped to extend longer on either side of the scraper shaft 3.

This blade also has a reinforcing plate 331 similar to the blade of the stirring blade 22.
Since the device is removably attached to the device, it can be completely cleaned after use and can always be kept in a clean state.

Note that the stirring blade 22 and the scraper 3 may be replaced as necessary.
It is also recommended to provide auxiliary blades at predetermined positions on each of the shafts 2 and 3 or at predetermined positions on the auxiliary plates 221 and 331 in order to make stirring more effective.

Further, depending on the viscosity of the food, it is not necessary to have both the blades 22 and the scraper 32, and it goes without saying that each has a sufficient stirring function by itself.
