Description

  The present invention relates to a method and apparatus for producing a food with irregular patterns.

Traditionally, two or more food ingredients are prepared separately, and the two or more food ingredients are mixed inhomogeneously to the extent that they can be visually observed without completely fusing them together. Some foods have a unique irregular pattern. Such foods have the advantage of being able to enjoy the taste of each ingredient individually, and are also popular with consumers because of their beautiful design.
As foods with such irregular patterns, the main ingredients are frozen confectionery products that produce irregular patterns by kneading many types of frozen confections prepared using different flavors and pigments. The main ingredients are frozen desserts that are kneaded with secondary ingredients such as ice, sauce, jam, etc. and solid dairy products such as butter and cheese. The food etc. which produced the regular pattern can be illustrated.

Conventionally, the following techniques are known for producing foods with irregular patterns.
The techniques of Patent Document 1 and Patent Document 2 are intended to obtain a food having an irregular pattern by continuously mixing a main material and a sub-material using a static mixer (static mixer). That is, in Patent Document 1, the flow of the main material and the flow of the auxiliary material are merged by a T-shaped streamline controller, and each material is passed through the static mixer in a state where the flow of each material is combined. In Patent Document 2, the main material and the sub-material are combined while being separately sent by a piston pump, and then passed through a static mixer, and two kinds of materials are introduced. A partition is provided in the T-tube to control unnecessary mixing before reaching the static mixer.

Japanese Patent Laid-Open No. 2-255042 Japanese Patent Laid-Open No. 5-21844

By the way, the techniques of Patent Document 1 and Patent Document 2 are unsuitable for fine mixing of the main material and the submaterial, and are difficult to apply particularly when the physical properties (viscosity, etc.) of the main material and the submaterial are significantly different. Met. For example, when the viscosity of the main material is low and the viscosity of the secondary material is high, the secondary material tends to flow unevenly on the wall surface of the static mixer, and the food in which the secondary material is unevenly arranged in the main material There was a problem of becoming.
In this regard, when the mixing performance of the static mixer is increased, the pressure loss increases, so it is necessary to increase the capacity of the conveying means for the main material and the auxiliary material. There is a problem that it is complicated and disadvantageous in terms of equipment cost and workability.
Therefore, the present invention is able to develop irregular patterns by suppressing unevenness of food materials, reducing equipment costs, improving work efficiency, and making the equipment relatively compact. It is an object to provide a manufacturing apparatus and a manufacturing method.

In the manufacturing method of the present invention, a main material having fluidity and a submaterial having fluidity are caused to flow into the first pipe, and the main material and the submaterial are caused to flow in the axial direction of the first pipe. Flow along,
The main material and the submaterial are discharged into a second pipe having a cross-sectional area larger than that of the first pipe, and the submaterial is scattered in an irregular pattern in the main material. It is characterized by being poured out from the second conduit and molded into a food.
According to this configuration, the main material and the sub-material that have flowed in the axial direction in the first pipe line are preferably at least 40 degrees with respect to the axial direction in the flow direction. Preferably, the second pipe is discharged in a radial direction so that the cross-sectional area of the flowing main material and sub-material is rapidly increased so that the cross-sectional area of the main material and the sub-material flow. Therefore, the sub-material is dispersed in the whole main material while being expanded in the second pipe line or finely torn and not fused into the main material. That is, according to the method of the present invention, the secondary material having an irregular pattern formed on almost the entire main material is scattered without the main material and the secondary material being fused and mixed so as to be homogeneous as a whole. Can. In this case, it is preferable to arrange the second pipeline so as to communicate with the downstream side of the first pipeline. Further, the step of discharging the main material and the sub-material to the second pipe having a larger cross-sectional area than the first pipe may be performed a plurality of times, but may be performed only once, or may be performed once. If there is, it is convenient and preferable.

  In the present invention, the step of causing the main material and the sub material to flow along the axial direction of the first pipe line may be performed while pressurizing the main material and the sub material. According to this configuration, since the main material and the sub-material are discharged more vigorously when being discharged to the second conduit, the sub-material is easily dispersed throughout the main material, and irregular patterns can be easily formed. Can be formed. As a specific method of such pressurization, it is convenient and preferable to reduce the diameter of the flow path of the first pipeline.

In the present invention, the step of causing the main material and the sub material to flow into the first pipe line includes the step of placing the sub material in the axial direction inside the main material flowing in the axial direction of the first pipe line. It is preferable that it is made to flow.
According to this configuration, since the secondary material flows in along the flow of the main material, the flow position of the secondary material in the primary material (that is, the flow of the primary material) when the primary material and the secondary material flow in the first pipe. The flow position of the secondary material in the cross section) can be made constant. Therefore, by making the sub-material flow toward a predetermined position in the main material, that is, closer to the center in the axial direction of the main material, it is easy to disperse the sub-material in the main material evenly when discharging to the second conduit. Can do.

In the present invention, even if the step of flowing the main material and the sub-material into the first pipe line pours the sub-material from a plurality of pipe lines toward the first pipe line. Good.
According to this configuration, since the secondary material is divided into a plurality of parts in advance in the first pipeline, the secondary material can be more easily dispersed throughout the main material when discharged to the second pipeline. it can.

In the present invention, the main material may be a compressive fluid, and the sub-material may be an incompressible fluid.
In general, foods containing air bubbles, such as frozen desserts, whipped cream, meringues, etc., are compressible fluids whose volume decreases when pressure is applied. When the main material is a compressive fluid and the submaterial is an incompressible fluid, for example, the submaterial may be stirred in the main material by using a mechanical stirrer with a static mixer or the like. However, there is a problem in that it is difficult to disperse the sub-materials in the main material and to disperse the sub-materials substantially evenly to develop an irregular pattern.
However, according to the method of the present invention, the secondary material is discharged by increasing the flow cross-sectional area of the primary material and the secondary material in the second conduit and discharging the primary material and the secondary material, preferably radially expanding. Is dispersed in the main material. Therefore, even if the main material is a compressive fluid, it is possible to suppress the unevenness of the sub-materials.

The manufacturing apparatus of the present invention is connected to a first pipe that joins a fluid main material and a fluid submaterial, and an open end on the downstream side of the first pipe. A second pipe having a larger diameter than the second pipe, and a filling device for the main material and the sub-material provided downstream of the second pipe. The first pipe is opened from the opening end of the first pipe at an angle of not less than 45 degrees and not more than 120 degrees in a side view with respect to the axis of the first pipe.
According to this configuration, the pipe line of the second pipe is expanded from 45 degrees to 120 degrees with respect to the axis of the first pipe from the opening end of the first pipe. The pipe line of the second pipe is rapidly expanded from the opening end of the first pipe. Therefore, when the main material and the submaterial are discharged to the pipe line of the second pipe, the flow cross-sectional area rapidly increases, and the second material is not fused into the main material. Preferably, it is spread radially in the pipe line or finely torn and dispersed throughout the main material. That is, according to the apparatus of the present invention, the main material and the submaterial are fused and mixed so as to be homogeneous as a whole, and the submaterial in which an irregular pattern is formed almost entirely in the main material is scattered. be able to.

In the present invention, a reduced diameter portion that gradually decreases in diameter toward the downstream may be formed in the pipe line of the first pipe.
According to this configuration, it is possible to apply pressure to the main material and the auxiliary material in the reduced diameter portion. Accordingly, since the main material and the sub-material can be discharged more vigorously when discharging to the second pipe line, the sub-material is more easily dispersed throughout the main material, and an irregular pattern is easily formed. be able to.

According to the present invention, a main material supply pipe capable of continuously supplying the main material is connected to the first pipe, and a distal end portion of the sub material supply pipe capable of continuously supplying the sub material includes the main material supply pipe. It is preferable that the material is inserted at a position where the material flows along the axis of the first pipe, and the axis of the sub-material supply pipe is arranged in parallel to the axis of the first pipe.
According to this configuration, the auxiliary material can be introduced along the flow of the main material. Therefore, when the main material and the sub material flow in the first pipe, the flow position of the sub material in the main material (that is, the flow position of the sub material in the flow cross section of the main material) can be maintained. Therefore, by making the sub-material flow in a predetermined position in the main material, that is, closer to the axial center of the main material, it is easy to disperse the sub-material in the main material evenly when discharging to the second conduit. Can do.

In the present invention, the sub-material supply pipe may be branched into a plurality at least at the tip portion.
According to this configuration, the auxiliary material can be divided into a plurality of parts and flow in the first pipe. Therefore, the secondary material can be more easily dispersed throughout the main material when discharged into the second pipe.

According to the method and apparatus for producing an irregularly shaped food according to the present invention, the flow direction of the main material and the auxiliary material, which are flowed in the axial direction in the first conduit, is preferably in a side view. In order to expand at 40 degrees or more and less than 90 degrees with respect to the axial direction, it is preferably discharged radially through the second conduit, and the cross-sectional areas of the flowing main material and submaterial are rapidly expanded. Therefore, the secondary material is not fused into the main material, but is spread in the second conduit, preferably radially spread or finely torn and dispersed throughout the main material. That is, according to the method of the present invention, the sub-material is present inhomogeneously in substantially the entire main material without mixing so that the main material and the sub-material are fused together and become homogeneous as a whole. The sub-material can be interspersed so that an irregular pattern is developed.
Therefore, according to the present invention, the presence of the sub-material can be perceived moderately and visually in the main material, and a highly aesthetic food can be provided. .
In addition, according to the method and apparatus of the present invention, since the manufacturing process and the configuration of the apparatus can be simplified, the apparatus can be reduced in size, equipment costs can be suppressed, and workability is improved. There is an effect that can be.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of a food production apparatus (hereinafter referred to as “food production apparatus”) and a production method having an irregular pattern according to the present invention will be described with reference to the drawings. Examples of foods that can be produced by the production method of the present invention include, for example, frozen confectionery products obtained by kneading many types of frozen confectionery prepared using different flavors and pigments to produce irregular patterns, and frozen confectionery. The main ingredients are frozen desserts that are kneaded with secondary ingredients such as ice, sauce, jam, etc., and solid dairy products such as butter and cheese, and secondary ingredients such as jam and sauce. And the like, in which the main material and the sub-material are made into a fluid at the time of the raw material, such as a food that has been kneaded to produce irregular patterns.

  As shown in FIG. 1, the food manufacturing apparatus 1A of the present invention includes a first pipe 2A that joins the main material P and the sub-material Q of food, and an open end 2a on the downstream side of the first pipe 2A. A second pipe 3 that is connected and has an inner diameter m2 of the pipe 3k larger than the inner diameter m1 of the open end 2a (having a larger cross-sectional area), and provided downstream of the second pipe 3. And a filling device 4.

The first pipe 2A is a cylindrical straight pipe, and the main material P and the submaterial Q of the food are joined together, and the main material P and the submaterial Q are directed to the second pipe 3 in the direction of the axis L (this embodiment). This is a pipe that flows vertically downward).
As shown in FIG. 2, a main material supply pipe 5 that supplies the main material P and a submaterial supply pipe 6 that supplies the submaterial Q are connected to the first pipe 2 </ b> A.
The main material supply pipe 5 and the sub material supply pipe 6 are connected to the first pipe 2 </ b> A via a joint of a T-shaped pipe 7.

The main material supply pipe 5 is a pipe through which the main material P flows continuously.
In the present invention, “continuously” means that the main material P is allowed to flow without interruption using a rotary pump or the like, and the main material P is intermittently shot one by one using a reciprocating pump, an on-off valve, or the like. Also included is a mode of flowing.

Connected to the upstream end of the main material supply pipe 5 is a main material manufacturing apparatus 8 such as a freezer having a tank 8a for storing the raw material of the main material. The main material P is supplied to the main material supply pipe 5 immediately after being manufactured by the main material manufacturing apparatus 8. The main material supply pipe 5 may be further provided with a liquid feeding means (pump or the like) for flowing the main material P. The downstream end of the main material supply pipe 5 is connected to a branch pipe 9 of a T-shaped pipe 7 connected to the first pipe 2A.
The main material supply pipe 5 may be connected to a hopper or tank that stores the manufactured main material P.

The secondary material supply pipe 6 is a pipe through which the secondary material Q flows continuously.
A hopper or tank 10 for storing the secondary material Q is directly connected to the upstream end of the secondary material supply pipe 6. The secondary material supply pipe 6 is further provided with a liquid feeding means (pump or the like) 11 for flowing the secondary material Q. The secondary material supply pipe 6 is connected to the upper end 12a of the main pipe 12 in a state in which the distal end portion 6a is inserted into the main pipe 12 constituting the T-shaped pipe 7 connected to the first pipe 2A. Has been.

The auxiliary material supply pipe 6 is arranged in parallel to the axis L of the first pipe 2A (in this embodiment, the axis L is a common axis), and the distal end portion 6a of the auxiliary material supply pipe 6 is formed of the main material P. Is supplied in the vicinity of the lower end 12b of the T-shaped tube 7 or in the first pipe 2A (in the present embodiment, so as to reach a position where the main material P flows along the axis L of the first pipe 2A). It is inserted and arranged in the vicinity of the lower end 12b of the T-shaped tube 7.
The secondary material supply pipe 6 may be directly connected to a secondary material Q manufacturing apparatus (not shown).

  In addition, as the main material P, various foods can be selected, but those that can be fed through a pipeline are desirable, and it is necessary for the food to have fluidity. As such food, in addition to various frozen desserts, dairy products such as butter and soft cheese are preferable, and other examples include desserts such as chocolate, yogurt, pudding, and jelly.

  The food that can most enjoy the effects of the present invention is a food having the property of a compressible fluid. The compressible fluid is a fluid whose volume increases or decreases depending on the size of the surrounding pressure, and a typical example is a foamed food. Examples include frozen confections such as ice cream and various whipped foods such as whipped cream, whipped butter and meringue. Of these, frozen dessert is most preferred.

  In the present invention, the frozen confectionery is defined by, for example, “Ministerial Ordinance Concerning Component Standards for Milk and Dairy Products”, and examples thereof include ice creams such as ice cream, ice milk, and lacto ice, and ice confections.

In addition, the auxiliary material Q may be any food as long as it is food, but it is necessary to have fluidity like the main material P.
The secondary material Q may be a compressive fluid, but is not particularly limited to a compressive fluid. Rather, the secondary material Q that can fully enjoy the advantageous effects of the present invention is an incompressible fluid that is not a compressible fluid.

  That is, even if a compressible fluid and an incompressible fluid are mixed, they are hardly mixed. For this reason, even if these are processed so as to exhibit a marble pattern, the incompressible fluid tends to be biased in the compressible fluid, and the incompressible fluid is hardened and unevenly distributed. Difficult to get. However, in the food manufacturing apparatus 1A, since the irregular pattern of the incompressible fluid can be formed in the compressible fluid, the superiority when the food manufacturing apparatus 1A is used becomes more remarkable.

The sub-material Q is preferably of a color different from that of the main material P. If the color is different, a more beautiful pattern can be drawn. Further, the secondary material Q is not limited to one type, and two or more types may be used.
The food manufacturing apparatus 1A is suitable when the physical properties of the main material P and the physical properties of the auxiliary material Q are different.

As shown in FIG. 1, the second pipe 3 is connected to the opening end 2a on the downstream side of the first pipe 2A, and the inner diameter m2 of the pipe line 3k is larger than the inner diameter m1 of the opening end 2a. It is a formed cylindrical tube.
The upper end of the second pipe 3 is closed by a flat plate 16 that is orthogonal to the axis L except for the opening 15 that connects the opening end 2a of the first pipe 2A, and the second pipe 3 is closed with respect to the direction of the axis L of the first pipe 2A. 90 degrees, that is, a straight pipe whose diameter is expanded in the horizontal direction.

  As an expansion ratio, the inner diameter m2 of the pipe line 3k of the second pipe 3 is 180 to 250%, preferably 200 to 250%, particularly preferably the inner diameter m1 of the opening end 2a of the first pipe 2A. It is desirable to set it to 220 to 250%.

  Further, the diameter θ1 of the diameter expansion may be 45 degrees or more and 120 degrees or less with respect to the direction of the axis L of the first pipe 2A, preferably 60 degrees or more and 100 degrees or less, more preferably 75. It is desirable that the angle is spread at a degree of 90 degrees or more.

When the angle of the upper end of the second pipe 3 with respect to the axis L direction of the flat plate 16 is 45 degrees or less, it is considered that the main material P and the sub-material Q are gently expanded and the stirring becomes insufficient.
Further, when the angle of the upper end of the second pipe 3 with respect to the axis L direction of the flat plate 16 is 120 degrees or more, the main material P and the submaterial Q that have flowed down in the axis L direction are in the axis L direction. Although it is considered that the flow direction cannot be changed by 90 degrees or more, it is considered that the main material P and the sub-material Q may stay above the pipe line 3k of the second pipe 3 due to the turbulent flow caused by stirring. It is done.
At the downstream end of the second pipe 3, a food product forming apparatus 20 including the main material P and the submaterial Q is provided.

  The product forming apparatus 20 is an apparatus for manufacturing a raw material of an irregularly-patterned food and then forming it into a final product form of the food. The raw material filling device 4, the product carrying-in / out means 21, and these Control means (not shown) for controlling movement.

The raw material filling device 4 is not shown in detail for each part, but means such as a weighing means for weighing food for one container, a liquid feeding means for feeding the food, or a piston pump having both of these functions And a filling nozzle 22 for pouring the main material P containing the sub-material Q, and an opening / closing valve for the filling nozzle 22, which are attached to the downstream end of the second pipe 3.
Below the raw material filling device 4, for example, loading / unloading means 21 such as a belt conveyor is installed so that a food container 25, a molding die or the like (the container 25 in this embodiment) is conveyed or forwarded. It has become.

Next, a method for manufacturing a food with an irregular pattern using the method for using the food manufacturing apparatus 1A will be described, and functions and operations of the food manufacturing apparatus 1A and the manufacturing method will be described.
First, as shown in FIG. 2, the main material manufacturing apparatus 8 of the main material P and the pump 11 of the sub material Q are operated to manufacture the main material P, and then the main material P and the sub material Q are respectively converted into the main material manufacturing apparatus. 8 and the tank 10 are sequentially fed to the main material supply pipe 5 and the sub-material supply pipe 6, respectively. Then, the main material P and the submaterial Q are supplied from the main material supply pipe 5 and the submaterial supply pipe 6 into the T-shaped pipe 7.

  At this time, since the main material P is connected to the tip of the branch pipe 9, the main material P enters from the branch pipe 9, and sequentially flows down while changing the traveling direction to the axis L direction of the main pipe 12. Since the secondary material Q is inserted so that the tip of the secondary material supply pipe 6 extends from the upper end 12a of the main pipe 12 to the vicinity of the lower end 12b, the flow direction of the main material P is determined in the direction of the axis L of the main pipe 12. It is supplied in the direction of the axis L which is the same direction as the main material P. Therefore, as shown in FIG. 1, the secondary material Q is supplied into the main material P according to the installation position of the secondary material supply pipe 6 in the first pipe 2A, and flows down toward the second pipe 3 as it is. To go. Thus, it is preferable that the front-end | tip of the submaterial supply pipe | tube 6 is opened toward the downstream of the flow direction of the main material.

  Then, when the main material P including the sub-material Q is discharged to the second pipe 3 by being sequentially pushed out of the main material P and the sub-material Q, the inner diameter m2 of the pipe line 3k of the second pipe 3 is discharged. Is expanded to 180% to 250% of the inner diameter m1 of the lower end opening 2a of the first pipe 2A, and the upper end flat plate 16 expands 90 degrees with respect to the axis L of the first pipe 2A ( That is, the main material P and the secondary material Q are flat at the upper end in the pipe line 3k of the second pipe 3 because the pipe line 3k is rapidly expanded in the horizontal direction so that the pipe line 3k expands 90 degrees with respect to the axis L. 16 preferably spread radially.

  And the secondary material Q changes the flow direction in the range of 0 degree to less than 90 degree | times with respect to the axis line L direction from the downstream edge of the pipe line 2k of the 1st piping 2A within the main material P. Thus, the presence of the sub-material Q can be perceived visually and tastefully without being melted and fused into the main material P, while being preferably spread out or torn away as a whole. The main material P is scattered over substantially the whole.

  The food material discharged into the second pipe 3 to form a pattern in which the sub-material Q is scattered in the main material P flows down the pipe line 3k of the second pipe 3 as it is, from the tip of the filling device 4 The product is poured into the container 25, and is appropriately frozen and solidified to obtain a frozen confectionery as shown in FIGS.

As described above, according to the food production apparatus 1A and the production method of the present invention, the main material P and the sub-material Q are mixed in the main material P without being mixed so that the main material P and the sub-material Q are fused and become homogeneous as a whole. The sub-material Q can be scattered so that an irregular pattern is formed on substantially the entire surface of the substrate.
Therefore, according to the present invention, the presence of the sub-material Q can be perceived moderately and visually in the main material P, and a food with a rich taste and high aesthetics is provided. There is an effect that can be.

  In addition, according to the food manufacturing apparatus 1A and the manufacturing method of the present invention, the first pipe 2A in which the pipe 2k having a constant diameter is formed, and the inner diameter m1 of the first pipe 2A are rapidly expanded to form the pipe 3k. Manufacturing a food with an irregular pattern with a simple manufacturing process and apparatus configuration in which the main material P and the sub-material Q are allowed to flow through the second pipe 3 having an inner diameter m2 of a large diameter. Can do. Therefore, it is possible to reduce the size of the food manufacturing apparatus 1A, to suppress the equipment cost and running cost, and to obtain the effects that workability, maintainability, and handling can be made suitable.

Moreover, since the front-end | tip part 6a of the submaterial supply pipe | tube 6 is arrange | positioned along the main pipe 12 of the T-shaped pipe | tube 7, and the lower end 12b vicinity, the submaterial Q is made into the main material by the predetermined arrangement | positioning of the main material P. It can be made to flow along the flow of P. Therefore, when the main material P and the sub material Q flow in the first pipe 2A, the flow position of the sub material Q in the main material P (that is, the flow position of the sub material Q in the flow cross section of the main material P) is maintained. be able to. Therefore, the secondary material Q is caused to flow in a predetermined position in the main material P, that is, near the center of the main material P in the axis L direction, so that the secondary material Q is discharged into the main material P at the time of discharge to the pipe line 3k. The effect that the material Q can be easily dispersed without unevenness is obtained.
Furthermore, since the food with an irregular pattern can be continuously manufactured by the food manufacturing apparatus 1A, an effect of industrially mass-producing can be obtained.

  Next, a second embodiment of the present invention will be described with reference to FIG. In the present embodiment, the same components as those in the first embodiment are denoted by the same reference numerals, description thereof is omitted, and differences from the first embodiment are mainly described.

  In the food manufacturing apparatus 1B having an irregular pattern according to the present embodiment, the first pipe 2B is gradually reduced in diameter toward the tip, and the pipe line 2k is the reduced diameter portion 30. And the 2nd piping 3 is connected to the opening end part 30b of the downstream of this 1st piping 2B.

  The diameter-reduced portion 30 is desirably reduced in diameter by 180 to 250%, preferably 200 to 250%, particularly preferably 220 to 250% with respect to the inlet opening 30a. It is suitable if the inclination angle of the inner wall surface 30t of the reduced diameter portion 30 is 5 to 45 °, preferably 5 to 30 °, particularly preferably 5 to 15 °.

  According to the food manufacturing apparatus 1B having the irregular pattern, when the main material P and the sub-material Q are supplied to the reduced diameter portion 30 of the first pipe 2B and are gradually advanced to the downstream side, the main material P and the sub-material are obtained. Q is pressurized. And when it discharges to the 2nd piping 3, since it will be released from pressure and main material P and submaterial Q will spurt in the 2nd piping 3 preferably, preferably in the direction of an axis L As a result, the flow angle θ2 becomes larger and the effect of disturbance becomes larger. As a result, the sub-material Q can be more finely dispersed in the main material P, a visually delicate and beautiful irregular pattern can be exhibited, and the presence of the sub-material Q can be perceived tastefully. The effect that it can be made into a delicate taste that can be produced is obtained.

  As described above, the food manufacturing apparatuses 1A and 1B according to the first embodiment and the second embodiment have been described with respect to the food manufacturing method according to the present invention, and the food manufacturing apparatuses 1A and 1B and the manufacturing method according to the present invention. Is not limited to the mode shown in the above embodiment. That is, according to the present invention, the main material P and the sub-material Q are applied to the second pipe 3 in which the inner diameter m2 of the pipe line 3k is formed larger than the inner diameter m1 of the downstream end from the first pipes 2A and 2B. The device or method can change the flow direction of the main material P and the sub material Q by preferably changing the flow direction of the first pipe 2A from 40 degrees to less than 90 degrees with respect to the direction of the axis L of the first pipe 2A. If so, each configuration can be appropriately modified and applied.

Specifically, in the first and second embodiments, one submaterial supply pipe 6 is inserted into the T-shaped tube 7. The submaterial supply pipe 6 is shown in FIG. In this way, a plurality of T-tubes 7 or a plurality of the tubes arranged equally near the axis L of the pipe line 2k of the first pipe 2A may be used. In this way, by inserting the auxiliary material supply pipe 6 into a plurality of parts, the auxiliary material Q can be joined to the main material P without being biased. Moreover, according to this modification, the effect that it can disperse | distribute more easily is obtained even if it is materials, such as jam with high viscosity, for example. In this way, the method of branching the auxiliary material supply pipe 6 into a plurality of branches and inserting it into the T-shaped pipe 7 is also effective in the food manufacturing apparatus 1B of the second embodiment.
This aspect is more suitable when the sub-material Q is a liquid or semi-liquid fluid than when it is a solid-liquid mixed fluid such as a pulp-containing sauce.

  Moreover, although the aspect which arrange | positions all the some secondary material supply pipe | tubes 6 to the T-shaped pipe | tube 7 or the 1st piping 2A may be sufficient, after combining some sub-material supply pipe | tubes 6 beforehand, it may be further. The aspect arrange | positioned to the T-shaped tube 7 or the 1st piping 2A may be sufficient. In this way, since a plurality of types of sub-materials can flow through the combined sub-material supply pipe 6, it becomes possible to present a more complicated irregular pattern.
