Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a stirring device and a stirring method used for the production of confectionery having bubbles such as foaming of a viscous material containing, for example, eggs, flour, fats and the like, and sponge cake, and particularly requires fine and uniform bubbles. The present invention relates to a stirrer and a stirring method that are optimal for kneading and kneading that does not require whipping and gluten generation of wheat flour, and also for tempering products using ingredients that are easily destroyed by stirring such as salads.
[0002]
[Prior art]
Generally, stirring by a conventional stirring device is performed in a state where a single main shaft is suspended from above in a material container. For example, as shown in Japanese Utility Model Publication No. 55-29498 and Japanese Utility Model Publication No. 2-9884, a whipper is provided at the lower end of a single vertical shaft, and the whipper is placed in the material container from the upper surface opening of the stirring container. There is a stirring method that inserts and revolves and rotates the whipper together with the shaft.
However, due to the structure of the whipper, when the capacity of the stirring vessel increases, the rotation trajectory tends to become rough. Therefore, when stirring and kneading a product that requires fine and uniform bubbles using a stirrer having a single vertical axis, there is a limit to the ideal capacity, and when the capacity is exceeded, fine and uniform bubbles are obtained. There is a problem that it becomes difficult. Further, when using wheat flour, there is a problem that if the kneading time is increased in order to obtain sufficient air bubbles, the production of gluten is promoted and the quality of the product is significantly impaired.
[0003]
By the way, when foaming foam such as sponge cake and whipped cream, it is a condition for producing a good quality product to make the bubbles as fine and uniform as possible, and perform foaming with high density and low specific gravity. In order to satisfy this condition, for example, it is indispensable to reduce the thickness of the wire of the whipper as much as possible, increase the number of wires, and rotate at a high speed so as to enclose air as much as possible. Further, in order not to leave unstirred material on the wall surface of the stirring vessel, it is necessary to minimize the clearance between the wall surface of the ball (stirring vessel) and the whipper (stirring device).
[0004]
When foaming a relatively small amount of food material, it is relatively easy to satisfy the above conditions. However, when foaming a large amount of food material at a time, it is necessary to increase both the capacity of the ball and the size of the whipper, and it is also necessary to increase the maximum diameter of the whipper. For this reason, there is a risk of causing a contact accident on the wall surface of the stirring container because the whipers are twisted and deformed without being able to withstand the centrifugal force when the food material is stirred and kneaded. Therefore, in order to avoid the above-mentioned danger at the time of mechanical mass production, it is necessary to make the wire of the whipper thicker or deepen the ball so that the shape of the whipper is not easily deformed by centrifugal force. .
[0005]
However, if the wire of the whipper is thickened, there is a problem because only large bubbles are generated during stirring and kneading. That is, when the size of each bubble generated during stirring and kneading increases, the surface tension of the food material that forms the bubble is destroyed without endurance, and the bubble and the bubble combine to create a larger bubble. , It causes a kind of chain reaction that absorbs the next bubble, which accelerates the deterioration of product quality.
Moreover, in order to make bubbles with high density and low specific gravity as much as possible, it is necessary to embed a large amount of air, and for that purpose, it is necessary to bring air into contact with the food material as much as possible. However, when a deep ball is used, an area where the food material comes into contact with air is reduced as compared with a shallow ball, and thus there is a problem that it is difficult to entrap the food material with sufficient air.
[0006]
[Problems to be solved by the invention]
In order to solve these problems, for example, a stirrer (vertical twin mixer) that rotates two vertical shafts inserted from above at high speed or a method of forcibly blowing air is employed. However, stirring by these methods has not yet completely solved the above problem. For this reason, in a mechanical production process that requires high quality, production is performed using a stirring device for a required production amount with a maximum capacity of a 30-liter vertical mixer.
[0007]
However, when using a large number of stirrers, it usually requires a lot of space and manpower, and the production efficiency is poor and it is necessary to move small batches many times in the factory. The risk of this also increases. In addition, it is not preferable because quality may vary due to individual differences among individual stirring devices. Therefore, it has been desired to develop a stirring device capable of foaming a large amount of food material with high quality without using a large number of stirring devices.
Thus, the present invention has been made to solve the above-mentioned problems, and the object of the present invention is to increase the contact area between the food material and air during agitation to agitate a large amount of food material at once in a short time. An object of the present invention is to provide a stirring device and a stirring method capable of kneading and easily making fine uniform bubbles.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the inventor has intensively studied various stirring apparatuses and stirring methods. As a result, the present inventor has found that fine and uniform bubbles can be efficiently produced by stirring and kneading the food material with a stirrer in which a plurality of spindles for rotation intersect the extension of the vertical axis for revolution at a predetermined angle. The present invention has been completed.
[0009]
That is, one of the objects of the present invention is a stirring device having a stirring container for holding a food material and a stirrer for stirring the food material in the stirring container, The stirrer has a vertical shaft for revolving the stirrer and a plurality of stirrers, and each of the stirrers is detachably connected to a lower end portion of one support shaft, and the support shaft is connected to the stirrer. This is achieved by the stirring device characterized in that it can be tilted so as to intersect the extended line of the vertical axis at a predetermined angle (Claim 1).
[0010]
Another object of the present invention is to stir the food material by crossing each support shaft at a predetermined angle with respect to the extension line of the vertical axis during the stirring of the food material, and the food after the stirring is finished. When unloading the material, the support shafts are tilted toward the extension line side of the vertical shaft and pulled up to the vertical shaft side so that the predetermined angle exceeds the predetermined angle during the stirring. The stirring method is achieved by the above method (claim 7).
[0011]
In the stirring device of the present invention, the angle at which each of the support shafts intersects with the extension line of the vertical axis, the rotation direction of each of the support shafts, and the type of each of the stirrers can be the same or different. (Claim 2). Further, the crossing angle between the extension line of the vertical axis and each support shaft in the stirring device of the present invention can be set to 30 to 90 ° (Claim 3). Furthermore, the stirring container in the stirring device of the present invention is a bowl-shaped container having a convex protrusion at the substantially central portion of the bottom surface and an opening at the top, and the diameter of the opening is the depth of the stirring container. It can be at least 2.5 times (Claim 4). In the present invention, at least one stirrer can be selected from the group consisting of a wire whipper, spiral hook, fork hook, ribbon hook, scraper, and beater. When the stirrer is an eggplant-shaped wire whipper, the wire whiper may have a wire thickness of 1.8 to 3.6 mm and a maximum diameter of the wire whipper of 200 to 400 mm. (Claim 6).
[0012]
Furthermore, in the stirring method of the present invention, the predetermined angle during stirring can be set to 30 to 60 °, and the predetermined angle during stirring can be set to 60 to 90 °. Moreover, in the stirring method of this invention, the rotation speed of each spindle of the said stirrer can be made the same or different (Claim 9).
[0013]
In the stirring device and the stirring method according to the present invention, the respective support shafts are tilted so that the plurality of support shafts intersect the extended line of the vertical shaft at a predetermined angle. Thereby, the stirring device and the stirring device of the present invention are stirred while adjusting the angle of the support shaft so as to increase the contact area between the food material and the air, compared with the conventional stirring device having the fixed support shaft in the vertical state. -Kneading can be performed. Therefore, the stirring device and the stirring method of the present invention can supply fine uniform air bubbles to the food material. Further, the stirring device and the stirring method of the present invention can make the crossing angle of each spindle, the rotation direction, and the kind of each stirring bar the same or different, and complex stirring and kneading are possible. Moreover, the stirring apparatus of this invention can adjust freely the angle which a spindle and the extended line of a perpendicular axis cross | inters between 30-90 degrees. For this reason, the stirrer of the present invention can maximize the creation efficiency of bubbles entrapped in air, can produce fine uniform bubbles in a short time, and can be used for the stirring container when the food material is carried out. Removal or reversal can be facilitated. Furthermore, by making the diameter of the opening of the stirring container in the stirring device of the present invention 2.5 times or more of the depth, the surface area of the air that comes into contact with the food material at the time of stirring and kneading is increased, and more food is used. You can embed air. Moreover, when a wire whipper is used as a stirrer, the maximum diameter of the whipper and the number of wires can be increased while keeping the wire diameter thin. Thereby, the stirring apparatus of the present invention can easily create fine and uniform uniform bubbles.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the stirring device and the stirring method of the present invention will be described in more detail with reference to the drawings.
FIG. 1 is a schematic front view of an embodiment of the stirring device of the present invention, and FIG. 2 is a schematic explanatory view showing the state of the stirrer when the food material of the embodiment of the stirring device of the present invention is carried out. .
In one embodiment shown in FIG. 1, the stirring device of the present invention includes a vertical shaft 1, a first connecting member 2, a second connecting member 3, a support shaft 4, a support shaft fixing rod 5, a stirrer 6, and a support shaft angle adjustment. Motor 7, spindle rotation motor 8, bottom plate 10, upper plate 11, stirring vessel 12, stirring vessel support base 15, stirring vessel lifting motor 16, vertical shaft revolving motor 17, sprocket 18, belt 19 , Main frame 20, main frame upper part 20 ′, power supply device 21, and reversing device 22.
[0015]
As shown in FIG. 1, in the stirring device of the present invention, the stirrer body 9 is suspended from a predetermined position on the main frame 20 through the vertical shaft 1 and fixed at a predetermined height. In the main frame 20, a vertical axis revolving motor 17, sprockets 18 and 18, and a belt 19 are housed. Further, the support shafts 4 and 4, the first connection members 2 and 2, the second connection member 3, the support shaft fixing rod 5 and the support shaft angle adjusting motor 7 of the stirrer body 9 are between the bottom plate 10 and the top plate 11. The base plate 10 and the top plate 11 are surrounded by an outer peripheral plate (not shown) as necessary.
A power supply device 21 that supplies power necessary for the operation of the stirring device of the present invention to the vertical shaft 1 is fitted and fixed on the upper portion 20 'of the main frame.
[0016]
The vertical shaft 1 receives the rotational driving force from the vertical shaft motor 17 through the sprockets 18 and 18 and the belt 19 on the upper end side thereof, and can revolve the agitator body 9 at a predetermined rotational speed. The vertical shaft 1 can rotate in either the forward or reverse direction corresponding to the rotational direction of the vertical shaft revolving motor 17. By stirring and kneading with the rotation direction changed appropriately, the occurrence of stirring and kneading unevenness can be prevented and a smooth product can be finished.
The vertical axis revolving motor 17 is for revolving the vertical axis 1 and can drive the vertical axis 1 at a rotation speed of 20 rpm or less, including a stationary state (0 rpm). Thereby, the vertical axis | shaft 1 can rotate at the rotation speed of 0-20 rpm, Preferably it is 5-15 rpm, More preferably, it is the range of 8-12 rpm.
[0017]
The first connecting members 2, 2 and the second connecting member 3 are connected to the vertical shaft 1, and the support shaft rotating motor 8, the support shaft 4 and the stirrer 6 are connected through these connecting members. The spindle 4 has a spindle rotating motor 8 attached to the upper end side thereof, and a detachable stirring bar 6 attached to the lower end side thereof. The support shaft 4 is fixed to the bottom plate 10 by a support shaft fixing rod 5, and can be tilted about the support shaft fixing portion 23 by a support shaft angle adjusting motor 7. The length of the support shaft 4 can also be adjusted to a desired length for each support shaft by sliding the support shaft 4 in the vertical direction and using an adjusting screw (not shown).
[0018]
The support shaft 4 can rotate the stirrer 6 at a predetermined rotation speed by the rotational driving force of the support motor 8 for rotating the support shaft. The spindle rotation motor 8 can be driven at a rotation speed of 440 rpm or less, including a stationary state (0 rpm). Therefore, the rotation speed of the support shaft 4 at the time of stirring can be determined as appropriate depending on the food material to be stirred and kneaded. For example, it is preferable to rotate at 440 rpm in the foaming operation, and it is preferable to rotate at a low speed of 20 rpm or less in the case of powder combination.
[0019]
At least two support shafts 4 are provided, and can be further increased to three or four in accordance with the food material to be stirred and kneaded, the volume of the stirring container 13, and the like. As for the arrangement of the support shafts 4, for example, when there are two support shafts 4, each support shaft 4 can be installed in a parallel position, and when there are three support shafts 4, each support shaft 4. Can be placed at each vertex position of the triangle. Further, the rotation direction of the support shaft 4 can be rotated forward and backward by adjusting the rotation direction of the support motor 8 for rotating the support shaft. If desired, the rotation direction and the rotation speed can be appropriately set for each support shaft 4. It can be changed to complicate the stirring action.
[0020]
The angle of the support shaft 4 can be adjusted in the range of 30 to 90 ° with respect to the extension line of the vertical shaft 1. For example, during the stirring and kneading of the food material, the vertical shaft is extended by adjusting the support shaft 4 to a crossing angle of 30 to 60 °, preferably a crossing angle of 40 to 50 °, more preferably a crossing angle of 45 °. Can cross the line. By adjusting the crossing angle during stirring and kneading to the above range, the gap between the stirrer 6 connected to the lower end portion of the support shaft 4 and the food material, that is, the rotational force of the stirrer 6 and the stirrer 6 Grooves (gap) generated between the food materials can be increased, and the amount of air in the food material can be increased. As a result, the contact area between the food material and air increases, and many fine uniform bubbles can be generated.
Further, as will be described later, when the food material is carried out, the above-mentioned angle is adjusted in the range of 60 to 90 °, preferably in the range of 80 to 90 °, more preferably 90 °, so that the support shaft 4 is in the direction of the vertical axis 1. The food material can be easily carried out while being pulled up to the side (see FIG. 3).
[0021]
If the said crossing angle of the support shaft 4 is within the range, it can be freely changed for each support shaft. The crossing angle of the support shaft 4 adjusts the connection angle between the first connection members 2 and 2 and the second connection member 3 connected to the vertical shaft 1 and the support shaft 4 by operating the support shaft angle adjusting motor 7. Can be adjusted.
[0022]
The crossing angle and the rotation direction of each support shaft may be the same for all support shafts 4 or may be different for each support shaft 4. By appropriately adjusting the crossing angle and rotation direction of each support shaft 4 and the extension line of the vertical shaft 1, suitable stirring conditions corresponding to the food material, the volume of the stirring container, and the like can be realized. Thereby, air can be efficiently embraced in the food material to be used, fine uniform air bubbles can be generated, and a high-quality product can be created. Moreover, the rotation speed of the support shaft 4 at the time of stirring can also be suitably adjusted for every support shaft according to the kind of the stirring element 6 attached to the lower end of the support shaft 4.
[0023]
As shown in FIG. 3, the support shafts 4 at the time of carrying out the food material after the agitation end are provided with support shaft fixing portions 23 of the support shafts 4 (locations where the support shaft 4 is fixed to the support shaft fixing rod 5). As the fulcrum, each support shaft 4 can be pulled up to the vertical shaft 1 side while tilting each support shaft 4 in the extension line direction of the vertical shaft 1. That is, the support shafts 4 and 4 fixed at a predetermined crossing angle with respect to the extension line of the vertical shaft 1 are used to rotate the vertical shaft about the support shaft fixing portion 23 as a fulcrum using the support shaft angle adjusting motor 7 after the stirring. 1 is tilted in the direction of the extension line 1 and adjusted so that the crossing angle is at least larger than the crossing angle during stirring, and the support shafts 4 and 4 are moved to the bottom plate 10 side of the stirrer body 9 in which the vertical shaft 1 is housed. Can be raised. By pulling up the support shafts 4 and 4 in the direction of the vertical axis 1 in this way, the reversing operation of the stirring container when the food material is carried out can be performed in a small space, so that the height of the stirring device itself can be reduced. . Moreover, the operation | movement which pulls up each spindle 4 and 4 to the vertical axis | shaft 1 side can be performed not only at the time of carrying out foodstuff but also when holding foodstuffs as needed.
[0024]
The size and depth of the stirring container 12 increases in proportion to the amount of food material to be stirred. When the food material is agitated using the agitating container 12 having a depth, in order to prevent the agitator 6 attached to the lower end portions of the support shafts 4 and 4 from coming into contact with the agitating container 12 at the time of carrying out. Therefore, it is necessary to maintain the distance between the stirring vessel support 15 and the stirrer body 9 by that amount. That is, when using the stirring container 12 having a depth, it is necessary to increase the total height of the stirring device by that amount. However, when the total height of the stirring device is increased, the height of the ceiling is restricted, and thus there are inconveniences such as a limited installation location.
Therefore, if each support shaft 4 can be tilted and pulled up toward the stirrer main body 9 at the time of unloading as in the stirring device of the present invention, the overall height of the stirring device can be designed to be low. It has an excellent merit that it is difficult to receive.
[0025]
One stirrer 6 is detachably connected to the lower end of one support shaft 4. The stirrer 6 is for stirring and kneading the food material, and various stirrers can be exchanged depending on the properties of the food material. For example, as the type of the stirrer 6, for example, a well-known stirrer can be appropriately selected and used in addition to a wire whipper, a spiral hook, a fork hook, a ribbon hook, a scraper, a beater, and the like. The kind of each stirring element 6 may be the same or different, and can be appropriately changed according to the food material and the volume of the stirring container 12. Moreover, the kind of each stirring element 6 can also be changed suitably in the middle of stirring.
[0026]
When the stirrer 6 is a wire whipper, the wire thickness of the wire whipper is preferably in the range of 1.8 to 3.6 mm, and more preferably in the range of 2.0 to 2.5 mm. If a wire with a thickness in the range of 1.8 to 3.6 mm is used, the wire will not be deformed during stirring and kneading, and bubbles generated by stirring and kneading will be reduced, and the density will be uniform. Can make small bubbles.
[0027]
The wire whipers are bent in an eggplant shape so as to be bilaterally symmetric at the approximate center of the wire of a predetermined length, and both ends of the wire are fixed to the outer peripheral surface of an attachment handle (not shown) by appropriate means, The wires are arranged so that the curved portions of the wires intersect radially. The maximum diameter of the wire whipper, that is, the maximum diameter in the vertical cross-sectional circle with respect to the longitudinal direction of the eggplant-like shape formed by a plurality of wires, can be appropriately selected according to the food material and the volume of the stirring container 12. The maximum diameter of the wire whipper is preferably in the range of 200 to 400 mm, more preferably in the range of 200 to 300 mm, and even more preferably 240 mm. If the wire whipper having a maximum diameter in the range of 200 to 400 mm is used, even if the food material is stirred at high speed, the wire loop is twisted and deformed, and there is little risk of contact with the wall surface of the stirring container 12.
[0028]
The stirring container 12 of the present invention can be a bowl-shaped container having a convex protrusion 13 at the substantially central portion of the bottom surface, and maintains a clearance (usually about 3 mm) that does not contact the stirring bar 6 on the vertical shaft 1. It can be placed vertically on the stirring vessel support plate 15.
The stirring container 12 has a convex protrusion 13 at a substantially central portion of the bottom surface thereof, and prevents unstirred and unkneaded food material from being deposited on the lower surface of the center of the stirring container during stirring and kneading. For this reason, uniform agitation / kneading without agitation / kneading unevenness can be realized by promoting convection of the food material from the lower surface of the agitation container 12. Although the magnitude | size and height of the convex-shaped protrusion 13 are not specifically limited, On the contrary, when it is too large or too high, the deposition to the bottom part of foodstuff material will be promoted. Therefore, the convex protrusion 13 is preferably about ¼ to の of the diameter of the stirring container 12, and more preferably about ６. Further, the height of the convex protrusion 13 is preferably about 1/8 to 1/12 of the height of the stirring container 12, and more preferably about 1/10.
[0029]
Further, the stirring container 12 of the present invention is designed so that the opening 14 is wider than a normal material container so that the food material can be sufficiently stirred and kneaded. The diameter of the opening 14 is preferably 2 to 3 times, more preferably 2.5 times the depth of the stirring vessel 12. In the stirring device of the present invention, the support shaft 4 intersects the extension line of the vertical shaft 1 at a predetermined angle, so that the depth of the stirring container 12 is made shallower than that of a stirring device equipped with a normal drooping support shaft, And it is preferable to make the opening part 14 wide. If the size of the opening 14 is at least 2.5 times the depth of the stirring container 12, more air can be brought into contact with the food material during stirring and kneading. It is possible to whipping less.
[0030]
In addition, the stirring container 12 of the present invention may have a heat insulation / cold insulation jacket structure as necessary. The heat insulation / cold insulation jacket structure is a container in which the stirring container 12 is constituted by a double structure composed of an inner wall and an outer wall, and an appropriate cold insulation agent and heat insulation agent are passed between the inner wall and the outer wall. By adopting a jacket structure, it is possible to appropriately select and maintain the optimum temperature for the food material, which is suitable for producing a product that requires high-quality foaming of the food material.
A well-known cold insulating material and a heat insulating agent can be used for a cold insulating material and a heat insulating agent, for example, cold water, warm water set to predetermined temperature, a vapor | steam, etc. can be mentioned.
[0031]
The stirring container 12 is placed on the stirring container support 15. The stirring vessel support base 15 can be raised and lowered by the driving force of the stirring vessel lifting motor 16. The stirring container support 15 can be lowered when the food material is held or carried out in the stirring container 12 and the stirrer body 9 can be taken out of the stirring container 12 (see FIGS. 1 to 3). Further, as shown in FIG. 3, in order to carry out the product from the stirring container 12 when the food material is carried out, the stirring container 12 is moved forward using an inverting device 22 connected to the stirring container support 15. Can be reversed. Note that the reversing operation by the reversing device 22 may be either manual or automatic.
[0032]
Next, the operation of the stirring device of the present invention configured as described above will be described below with reference to the drawings.
First, a predetermined amount of food material is placed in the stirring container 12. The food material used in the stirring device and the stirring method of the present invention is not particularly limited, and various food materials can be used. In particular, the stirring device and the stirring method of the present invention are used to prepare products using ingredients that are easily broken by stirring such as frothing that requires fine and uniform air bubbles, and that does not require the production of gluten of wheat flour, and further, such as salad. Work is optimal.
[0033]
Next, as shown in FIG. 1, the stirring container 12 is placed on the stirring container support 15 so that the convex protrusion 13 of the stirring container 12 holding the food material is directly below the vertical axis 1. After the stirrers 6 and 6 are attached to the lower ends of the support shafts 4 and 4, the agitator angle adjusting motor 7 is driven through the first connecting member 2, the second connecting member 3 and the support shaft fixing rod 5 to tilt. The stirrer angle adjusting motor 7 is stopped when it intersects the extended line of the vertical axis 1 at a predetermined angle. In this case, the crossing angle can be determined for each support shaft 4, and the crossing angles of the support shafts 4 and 4 may be the same or different.
In addition, it is desirable to attach the stirring bars 6 and 6 to the lower ends of the support shafts 4 and 4 in advance as described above, but the crossing angle with respect to the extension line of the vertical shaft 1 is determined as necessary. It can be installed later.
[0034]
Thereafter, the stirring container 12 is lifted by the stirring container lifting motor 16 to gradually bring the stirring container 12 closer to the stirrers 6 and 6, and when the predetermined clearance is reached, the stirring container lifting motor 16 is stopped. In this state, the spindle rotation motor 8 is started to start rotation of the spindles 4, 4 and the stirrers 6, 6, and at the same time, the vertical axis revolution motor 17 is started to revolve the vertical axis 1. At this time, the rotational speeds of the spindle rotation motor 8 and the vertical axis revolution motor 17 are determined in consideration of the type of food material and the volume of the stirring container 12.
[0035]
When fine and uniform bubbles are obtained by continuous stirring and kneading for a predetermined time, the driving of the spindle rotating motor 8 and the vertical axis rotating motor 17 is stopped, and the rotation of the stirring bar 6 and the stirrer are stopped. The revolution of the main body 9 is stopped. Thereafter, as shown in FIG. 3, the support shaft angle adjusting motor 7 is driven, and the support shafts 4, 4 and the stirrers 6, 6 are supported in the extension line direction of the vertical shaft 1 with the support shaft fixing portions 23, 23 as fulcrums. The support shafts 4 and 4 to which the stirrers 6 and 6 are attached are lifted to the bottom plate 10 side by tilting at least larger than the tilt angle during stirring. At this time, it is also possible to drive the stirring container lifting motor 16 as needed to lower the stirring container support 15 to a predetermined position. Thereafter, the reversing device 22 (see FIG. 2) is used to reverse the stirring container 12 on the stirring container support 15 forward, and the food material in the stirring container 12 is carried out.
[0036]
In addition, about the carrying-out operation | work of the said food material, it can also carry out directly from the lower surface of the container 12 for stirring using a pump other transfer apparatus, for example. With such an embodiment, the reversing operation of the stirring container 12 during the carry-out operation can be omitted, so that a continuous stirring and kneading operation can be performed.
[0037]
【The invention's effect】
As described above, according to the stirring device and the stirring method of the present invention, the plurality of support shafts are arranged so as to intersect the extension line of the vertical shaft at a predetermined angle, and therefore, compared with the vertical support shaft, Stirring and kneading can be performed in a state where the contact area of air with the food material is increased. For this reason, it is possible to improve the efficiency of creating bubbles in which more air is embraced, and it is possible to create a large amount of fine uniform bubbles in a short time. In particular, with the stirring device and the stirring method of the present invention, products using ingredients that are easily broken by stirring such as frothing that requires fine and uniform air bubbles and that do not require the production of gluten of wheat flour, and salad It is most suitable for the preparation work.
[0038]
Further, the stirring device and the stirring method of the present invention, when unloading the food material after the completion of the stirring and kneading operation, tilts the support shaft on which the stirrer is attached to the vertical shaft side by tilting the support shaft with the support shaft fixing portion as a fulcrum Therefore, even if it is a small space, it can be easily carried out, and the overall height of the stirring device can be designed low.
