JP 2003-135271 A

  In the conventional food manufacturing apparatus exemplified in Patent Document 1, the rotary hook is heated by the heating means arranged on the outer periphery of the rotary hook, but the hook main body rotates. Since there is a predetermined gap between the hook body and the heating means, the temperature of the rotary hook can be accurately and evenly heated by heating too much, insufficient heating, or local heating. It is difficult to control, and there are cases where unevenness in heating occurs with respect to foods, and quality variations due to temperature differences may occur.

  Accordingly, an object of the present invention is to provide a rotary food production apparatus capable of controlling the temperature of the pot body to be as accurate and uniform as possible.

  In order to achieve the above object, a rotary food production apparatus according to the present invention includes a bottom wall, a peripheral wall, and a hook body having an opening provided on the opposite side of the bottom wall, and a central portion of the bottom wall of the pot body. Further, a support shaft mounted perpendicularly to the bottom wall, a support base for rotatably supporting the support shaft, a driving device for rotating the support shaft, and a heating means or cooling for heating the hook body The heating means or the cooling means for heating or cooling the fluid jacket that is attached to the outer peripheral surface of the hook body and that forms a fluid flow path, and the fluid jacket through the support shaft. And a distribution means for distributing the fluid.

  According to the present invention, the fluid for heating or cooling is circulated through the fluid jacket attached to the outer peripheral surface of the hook body by the circulation means, so that the fluid is brought into direct contact with the hook body, and the temperature of the hook body is accurately measured. And can be controlled to be uniform. Therefore, a food with a more constant quality can be produced in food molding, coating, cooking, and the like.

  In the rotary food manufacturing apparatus of the present invention, the fluid flow path of the fluid jacket includes a flow path that flows from the bottom wall side to the opening side along the peripheral wall of the pot body, and the opening from the opening side. It is preferable that the flow path flowing to the bottom wall side is alternately repeated so as to circulate while meandering. According to this, the heating or cooling fluid flows along the peripheral wall of the hook body while meandering from the bottom wall side to the opening side, and then from the opening side to the bottom wall side. The temperature of the main body can be controlled more uniformly.

  In the rotary food manufacturing apparatus of the present invention, the fluid flow path has a high arrangement density in the central portion of the peripheral wall, and a low arrangement density in the portion of the peripheral wall close to the bottom wall and the opening. Preferably it is formed. According to this, when the hook body rotates, the food material tends to collect in the central portion of the peripheral wall by centrifugal force, but by increasing the arrangement density of the fluid flow paths in the central portion of the peripheral wall, Heating or cooling can be performed more efficiently.

  In the rotary food manufacturing apparatus according to the present invention, the fluid jacket is formed by joining the opening edge of the bowl-shaped member to the outer peripheral surface of the hook body and surrounding the bowl-shaped member with the outer peripheral surface of the pot body. It is preferable that the space to be formed is configured as a fluid flow path. According to this, while joining the outer peripheral surface of the said hook main body suitably bending the elongate member shape | molded in the bowl shape so that a cross section may make a U shape or U shape, for example, it is between edge parts. Since the fluid channel can be configured by connecting the two, the degree of freedom in designing the fluid channel and the manufacturing cost can be reduced.

  In the rotary food manufacturing apparatus according to the present invention, the fluid jacket covers a plurality of ribs joined so as to stand from the outer peripheral surface of the hook body, and covers the outer peripheral surface side and the side surfaces of these ribs. It is preferable that a space surrounded by the rib, the cover, and the outer periphery of the shuttle main body forms the fluid flow path. According to this, since the fluid flow path can be formed in a wider area of the outer peripheral surface of the shuttle main body, the heating or cooling efficiency can be increased.

  In the rotary food manufacturing apparatus of the present invention, the support shaft forms a double pipe having an inner cylinder and an outer cylinder, and the fluid flow path of the fluid jacket passes through a gap between the inner cylinder and the outer cylinder. A first flow path that communicates with one end of the fluid jacket and a second flow path that communicates with the other end of the fluid flow path of the fluid jacket through the inside of the inner cylinder, and the support base is capable of rotating the support shaft.

One of the passage and the second communication passage is preferably connected to the fluid introduction pipe, and the other of the first communication path and the second communication passage is connected to the fluid return pipe. According to this, the structure which distribute | circulates a fluid to the fluid jacket attached to the outer peripheral surface of a hook main body can be reliably and simply formed, rotating a hook main body.

  In the rotary food manufacturing apparatus of the present invention, it is preferable that the hook body has a convex curved shape in which the peripheral wall bulges outward in a cross section cut by a plane along the support shaft. According to this, when the hook body rotates, the food material rolls smoothly along the inner periphery of the peripheral wall of the hook main body and easily collects in the central portion of the peripheral wall. It can be effectively performed, and food can be molded and coated satisfactorily.

  According to the present invention, the temperature of the hook body is controlled to be as accurate and uniform as possible by circulating the heating or cooling fluid by the circulation means through the fluid jacket attached to the outer peripheral surface of the hook body. Therefore, it is possible to produce a food with a more constant quality in the formation, coating, cooking, etc. of the food.

As shown in FIG. 2, the peripheral wall 63 of this embodiment has a convex curved surface in which a central portion swells outward in a cross section cut along a plane along the support shaft 40, and is opposite to the bottom wall 61. The opening 65 is provided in the center portion of the reduced diameter (see FIG. 3).

  By the way, the shuttle main body 60 of this embodiment has the above-described shape of the peripheral wall 63 and has a shape like an onion as a whole, but may have a cylindrical shape, for example, and is not particularly limited. . The material of the hook body 60 is not particularly limited, but is formed of, for example, stainless steel or a metal such as Al or Cu, and stainless steel is particularly preferably employed.

  A fluid jacket 70 that forms a fluid flow path is provided on the outer peripheral surface of the peripheral wall 63 of the shuttle main body 60.

  As shown in FIG. 4, the fluid jacket 70 in this embodiment has a U-shaped cross section on the outer peripheral surface of the peripheral wall 63 of the hook body 60, and has a curved shape that fits the outer peripheral surface of the peripheral wall 63. A plurality of eaves-like members 71 elongated in the shape of eaves are arranged along the circumferential direction, and the opening edge thereof is joined to the outer peripheral surface of the peripheral wall 63 by welding or the like, and has a U-shaped cross section. The edge portion of the flange members 71 and 71 adjacent to each other is joined to the outer peripheral surface of the peripheral wall 63 by welding or the like at the opening edge of the flange member 73 bent in a substantially U shape. It is formed by joining together by welding or the like. A space surrounded by the flange-shaped members 71 and 73 and the outer peripheral surface of the peripheral wall 63 of the shuttle main body 60 is configured as a fluid flow path of the fluid jacket 70.

  Further, the joining of the hook-like members 71 and 73 to the outer peripheral surface of the peripheral wall 63 may be performed by, for example, an adhesive. Further, in this embodiment, the saddle-like members 71 and 73 for forming a fluid flow path have a U-shaped cross section. For example, the U-shaped or V-shaped cross section It may be.

Then, while joining to the outer peripheral surface of the peripheral wall 63 of the hook body 60 and connecting the end portions thereof, a fluid flow path can be formed. For example, the size of the hook body 60 and the convex curved surface The shape of the hook-shaped member 73 can be changed by changing the length and the degree of curvature of the hook-shaped member 71 according to the curvature, and there is a degree of freedom in designing the fluid flow path, and the manufacturing cost can be reduced. Can do.

  As shown in FIGS. 1, 2, and 7, in this embodiment, the fluid flow path of the fluid jacket 70 extends from the bottom wall 61 side along the extending direction of the peripheral wall 63 of the hook body 60. The flow paths 75 and 79 flowing to the opening 65 side and the flow paths 77 and 81 flowing from the opening 65 side to the bottom wall 61 side are alternately repeated, and are formed to circulate while meandering.

  FIG. 7 shows a developed view of the fluid flow path of the fluid jacket 70. With reference to FIG. 7, the flow path formation pattern of the fluid jacket 70 of this embodiment will be described in more detail.

  That is, as shown in FIG. 7, the fluid flow path of the fluid jacket 70 includes straight flow paths 75, 77, 79, 81 and bent flow paths 76, 78, 80, 82. . The straight flow paths 75 and 79 flow from the bottom wall 61 side to the opening 65 side, and the straight flow paths 77 and 81 flow from the opening 65 side to the bottom wall 61 side. And the flow path 75-> 76-> 77-> 78-> 79-> 80-> 81-> 82-> is repeated, and the meandering flow path is constituted as mentioned above.

  Of the straight flow paths, the flow path 75 is the longest, the flow paths 77 and 81 are the next longest, and the flow path 79 is the shortest, so that the bent portions 78 and 80 are convex on the peripheral wall 63. The bent portions 76 and 82 are located near the center of the curved surface, and the bent portions 76 and 82 are located away from the center of the convex curved surface of the peripheral wall 63. As a result, the bent portions 78 and 80 in which the return of the meandering path is short and the bends 82 and 76 in which the return of the meandering path is long are repeated in a predetermined order.

  For this reason, the arrangement density of the flow path is high at the central portion of the convex curved surface of the peripheral wall 63, and the arrangement density of the flow path is low at a portion away from the center of the convex curved surface.

  As shown in FIG. 1, a supply pipe 92 is connected to one end of the flow path of the fluid jacket 70, and a discharge pipe 93 is connected to the other end.

  Further, as shown in FIG. 8, a plurality of fluid flow paths of the fluid jacket 70 a extend from the bottom wall 61 side of the hook body 60 toward the opening 65 side and are arranged along the circumferential direction of the peripheral wall 63 of the hook body 60. The hook-shaped member 71 having the same length and the hook-shaped member 73a that is disposed at right angles to the longitudinal direction of the hook-shaped member 71 and connects the ends of the adjacent hook-shaped members 71, 71 are configured. In addition, a plurality of fluid flow paths arranged along the circumferential direction of the peripheral wall 63 may be configured to extend with the same length.

  Further, in the manufacturing apparatus 10, a fluid for heating or cooling (oil heated to a predetermined temperature, liquid such as hot water or cold water, steam, gas, etc.) is passed through the support shaft 40 to the fluid jacket 70. For example, a pump such as an axial pump or a centrifugal pump, a compressor, and the like.

  Next, an example of a method for using the manufacturing apparatus 10 having the above structure and its operation and effects will be described.

  The manufacturing apparatus 10 is made of, for example, food materials such as almonds, nuts such as peanuts, macadamia nuts and hazels, and cereals such as popcorn, corn flakes and wheat flakes, and coating materials such as chocolates, candies and sugars. Can be used for coating or forming a food material into a spherical shape, cooking noodles such as fried noodles and spaghetti, rice such as fried rice and pilaf, and other foods.

  In this embodiment, a procedure for producing a confectionery by coating a food material such as almond or hazelnut with a coating material such as melted chocolate or granulated sugar will be described. In addition, this manufacturing apparatus 10 can be used not only in this aspect but also when, for example, cooking fried noodles and fried rice, for example, and its use is not particularly limited.

  First, a circulation means such as a pump (not shown) is operated to circulate a fluid for heating or cooling, for example, a fluid such as oil heated to a predetermined temperature, into the fluid channel of the fluid jacket 70 through the channel. . That is, as shown in FIG. 6, the fluid that has flowed into the fourth communication hole 32a through the introduction pipe 35 flows into the gap 46 between the inner cylinder 41 and the outer cylinder 42 through the third communication hole 43b, Then, the fluid flows into the supply pipe 92 through the first communication hole 44 a and is supplied to the fluid jacket 70.

  In addition, the fluid discharged from the fluid jacket 70 flows into the second communication hole 44b through the discharge pipe 93, and flows into the inner cylinder 41 through the gap 45a. The fluid that has passed through the inner cylinder 41 passes through the communication hole 32b on the inner periphery of the rotary joint 32, passes through the inside of the connection pipe 34, and flows into the return pipe 36, whereby the fluid circulates. Yes.

  Then, the motor 53 is rotated, the support shaft 40 is rotated at a predetermined speed via both the sprockets 54 and 49 and the chain 55, and the hook body 60 is rotated.

  In this state, food materials such as almonds and hazelnuts and coating materials such as chocolate, candy and sugar are introduced from the opening 65 of the pot body 60, and the almonds, hazelnuts and the like are placed in the rotating pot body 60. The coating material is coated while rolling the food material. Thus, a composite confectionery can be obtained in which a coating material such as chocolate, candy or sugar is coated on the outer periphery of a food material such as almond or hazelnut so as to have a smooth curved appearance.

  And in this manufacturing apparatus 10, like the rotary food manufacturing apparatus which has the conventional gas heater, and the rotary cooking pot provided with the cylindrical heater of the electrical resistance heating or electromagnetic induction heating type of the said patent document 1 Unlike the structure in which heat treatment is indirectly performed from the outer periphery of the hook through a predetermined gap, a fluid jacket 70 having a fluid flow path is directly attached to the outer peripheral surface of the peripheral wall 63 of the hook body 60 by welding or the like. Since the structure is adopted, the temperature of the peripheral wall 63 of the hook body 60 can be controlled to be as accurate and uniform as possible by circulating a fluid for heating or cooling through the fluid jacket 70. As a result, the food material and the coating material can be heated or cooled so that the food material and the coating material are accurate and uniform at a desired temperature, so that food with a more uniform quality can be manufactured.

  Further, in this embodiment, as shown in FIG. 7, the fluid flow path of the fluid jacket 70 flows along the extending direction of the peripheral wall 63 of the hook body 60 from the bottom wall 61 side to the opening 65 side. Since the passages 75 and 79 and the flow passages 77 and 81 flowing from the opening 65 side to the bottom wall 61 side are alternately repeated and formed to circulate while meandering, the peripheral wall 63 of the hook main body 60 is formed. Can be controlled more uniformly.

  Further, in this embodiment, as shown in FIGS. 2 and 7, the fluid flow path of the fluid jacket 70 has a high arrangement density in the central portion of the peripheral wall 63 of the hook body 60, and the bottom wall 61 and In a portion close to the opening 65, the arrangement density is formed to be low. Therefore, when the hook main body 60 rotates, the food material tends to collect in the central portion of the peripheral wall 63 due to centrifugal force. However, by increasing the arrangement density of the fluid flow paths in the central portion of the peripheral wall 63, the food material Can be heated or cooled more efficiently.

  Further, in this embodiment, as shown in FIG. 2, the peripheral wall 63 of the hook body 60 has a convex curved surface in which the central portion swells outward in a cross section cut along a plane along the support shaft 40. Therefore, when the hook main body 60 rotates, the food material and the coating material roll smoothly along the inner periphery of the peripheral wall 63 of the hook main body 60 and easily gather at the central portion of the peripheral wall 63. Heating or cooling by the jacket 70 can be performed more effectively, and food can be molded or coated satisfactorily.

  In the rotary food manufacturing apparatus 10a (hereinafter referred to as “manufacturing apparatus 10a”) in this embodiment, the structure of the fluid jacket 70b is different from the fluid jackets 70 and 70a of the above embodiment.

  That is, as shown in FIGS. 9 to 11, the fluid jacket 70 b of this embodiment includes a plurality of ribs 85 joined so as to stand from the outer peripheral surface of the peripheral wall 63 of the hook body 60, and the ribs 85. It is comprised by the outer peripheral surface side cover 86 joined so that the outer peripheral surface side might be covered, and the side surface cover 87 joined so that the side surface side of the several rib 85 might be covered, These rib 85, outer periphery A space surrounded by the surface side cover 86, the side surface cover 87, and the outer peripheral surface of the peripheral wall 63 of the shuttle main body 60 forms a fluid flow path of the fluid jacket 70b.

  The hazelnut crocanth was manufactured using the rotary food manufacturing measures of Examples and Comparative Examples 1 and 2.

Example 1
The manufacturing apparatus 10 shown in FIGS. 1 to 7 was used. The outer diameter of the central portion of the peripheral wall 63 of the hook body 60 of the manufacturing apparatus 10 (the maximum outer diameter portion of the convex curved portion) is 140 cm, and the inner diameter of the opening 65 is 70 cm.

  And the shuttle main body 60 was rotated at the speed of 15 rpm with the drive device, circulating the machine oil heated to 185 degreeC by the distribution | circulation means in the fluid flow path (75-82) of the fluid jacket 70. FIG. After 5 minutes, after the surface temperature of the peripheral wall 63 of the pot body 60 reached 183 ° C., 15 kg of granulated sugar, 5 kg of corn starch, 40 kg of raw hazelnut, butter (containing lecithin 0.5%) while the pot body 60 continued to rotate. %) 500 g was charged from the opening 65 of the hook body 60. 15 minutes after charging, the temperature of the mixture such as sugar in the pot body 60 reached 180 ° C., and the granulated sugar began to melt. Furthermore, when the hook body 60 was rotated for 3 minutes and the melted granulated sugar began to be colored, the circulation of the machine oil in the fluid flow path of the fluid jacket 70 was stopped and the rotation of the hook body 60 was also stopped. Thereafter, the crocanth in which dark amber sugar adhered to the roasted hazelnut in the pot body 60 was taken out with a ball and poured into a metal container. Next, after the crocanth poured into the metal container was thinly spread on the cooling plate and cooled, the crocanto was mechanically crushed to produce a hazelnut crocanto. The hazelnut crocanth produced in this way is a confectionery product in which the hazelnut is roasted moderately and the surface is crispy and fragrant, and a food of a certain quality can be stably produced.

(Comparative Example 1: Gas heating type)
A manufacturing apparatus having substantially the same structure as the above manufacturing apparatus and having a gas heater disposed below the main body of the hook instead of the fluid jacket 70 was used. The dimensions of the hook body are the same as those in the first embodiment.

  And the gas heater installed under the hook main body was ignited, and the hook main body was rotated at the speed of 15 rpm. Three minutes later, after the surface temperature of the hook body reached 181 ° C., the same material and quantity as in Example 1 were added, and the rotation of the hook body was continued. Ten minutes after the addition, the temperature of the mixture such as sugar in the kettle body reached 180 ° C., and the granulated sugar began to melt. When heating the kettle body as it is, a part of the melted granulated sugar began to color rapidly before the entire granulated sugar melted. Furthermore, the kettle body was heated while rotating for 3 minutes, and immediately after the whole of the granulated sugar was melted, the gas heater was stopped to stop the rotation of the kettle body. After that, the crocanth with dark amber sugar attached to the roasted hazelnuts in the pot body was discharged with a ball and poured into a metal container. Next, after the crocanth poured into the metal container was thinly spread on the cooling plate and cooled, the crocanto was mechanically crushed to produce a hazelnut crocanto. The hazelnut crocanth produced in this way was unacceptable as a confectionery product because the hazelnut roast was uneven and the surface sugar was also partially burnt.

(Comparative example 2: Infrared heater heating type)
Instead of the fluid jacket 70, a manufacturing apparatus having an infrared heater disposed above the hook body was used instead of the fluid jacket 70. The dimensions of the hook body are the same as those in the first embodiment.

  And the infrared heater installed under the hook main body was ignited, and the hook main body was rotated at 15 rpm. After 20 minutes, when the surface temperature of the hook body reached 180 ° C., the same material and quantity as in Example 1 were added, and the rotation of the hook body was continued. Twenty-five minutes after the addition, the temperature of the mixture such as sugar in the pot body reached 180 ° C., and the granulated sugar began to melt. Further, the kettle body was rotated for 5 minutes, and when the melted granulated sugar began to be colored, the infrared heater was stopped and the kettle body was also turned off. After that, the crocanth with dark amber sugar attached to the roasted hazelnuts in the pot body was discharged with a ball and poured into a metal container. Next, after the crocanth poured into the metal container was thinly spread on the cooling plate and cooled, the crocanto was mechanically crushed to produce a hazelnut crocanto. The hazelnut crocanth produced in this way was a roasted hazelnut and a lack of crispness on the surface.
