BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings. FIG. 1 is a schematic front view of the entire food processing apparatus. In this device, bean jam G is supplied to the hopper 1 as a food material, and is fed to the extruder 5 by the vane pump 3. Similarly, bread dough F is supplied to the hopper 2 as a food material, and is pressure-fed to the extruder 5 by the vane pump 4. Then, as described later, the bean paste G is continuously discharged from the nozzle and extruded into a rod shape, and at the same time, the dough F is continuously discharged so as to cover the periphery of the bean paste G, and is continuously formed into a rod shape in a two-layer structure. Molded. The molded body H continuously formed in this manner hangs down and is cut by the shutter piece 6 at a predetermined length.

It is conveyed rightward in FIG. 1 to enter the next step.
[0013]
FIG. 2 is an enlarged sectional view of the extruded part 5 of FIG. 3 and 4 are cross-sectional views taken along planes AA and BB in FIG. 2, respectively. The bean paste G is pressure-fed by the vane pump 3, passes through the supply pipe 20, and is discharged from the inner nozzle 21 fixed downward to the supply pipe 20. On the other hand, the dough F is pumped by the vane pump 4 and passes through the supply pipe 22. The supply conduit 22 is formed downward so as to concentrically surround the supply conduit 20, and an outer nozzle 23 is fixed to an end thereof. Therefore, the dough F is discharged from the outer nozzle 23 so as to cover the dough F around the stick G discharged from the inner nozzle 21 in a rod shape.
[0014]
A mounting base 24 is fixed to an outer peripheral surface of a portion where the supply pipe 22 is formed so as to surround the supply pipe 20. A ring-shaped gear adapter 28 is arranged inside the mounting base 24 concentrically with the supply pipe line 22, as shown in the sectional view taken along the line AA of FIG. A gear 25 is formed on the outer peripheral surface of the gear adapter 28. A ring-shaped stirring adapter 29 is arranged between the supply pipe 22 and the gear adapter 28 concentrically with the supply pipe 22. An agitator 31 is provided on the inner surface of the stirring adapter 29 so as to protrude into the supply pipe 22. The gear adapter 28 is slidably held by a pair of liners 26, 26 provided on the mounting base 24, and the stirring adapter 29 is also slidably held by a pair of liners 30, 30.
[0015]
The gear 25 provided on the outer peripheral surface of the gear adapter 28 meshes with the drive gear 35 at the opening 34 of the mounting base 24. A driven pulley 36 is fixed to the driving gear 35, and a driving force of a motor 39 is transmitted by a belt 37 and a driving pulley 38. The rotation of the driving gear 35 causes the gear 25 to rotate, and the gear adapter 28 also rotates. A plurality of protrusions 32 are provided on the inner surface of the gear adapter 28, and a plurality of protrusions 33 engaging with the protrusions 32 are provided on the outer surface of the stirring adapter 29. Therefore, the rotation of the gear adapter 28 is transmitted to the stirring adapter 29 by the engagement of the projections 32 and 33, and the stirring adapter 29 rotates. The rotation of the stirring adapter 29 rotates the agitator 31 provided on the inner surface of the stirring adapter 29 in the supply conduit 22, so that the gluten of the bread dough is strengthened in the same manner as in the above-described prior art.
[0016]
As shown in FIG. 4, a ventilation path 27 is formed concentrically with the supply pipe 22 inside the mounting base 24. The air passage 27 has a cylindrical space extending vertically between the gear adapter 28 and the stirring adapter 29, and has a structure that opens downward. Air can flow between the gear adapter 28 and the stirring adapter 29 through a gap other than the engagement portion of the projections 32 and 33. An opening 42 communicating with the upper part of the ventilation path 27 is formed in the mounting base 24, and a cooler 40 for cooling the compressed air supplied from the compressor 41 is connected to the opening 42. .
[0017]
In FIG. 3, when the motor 39 is continuously rotated, the drive transmission mechanism generates heat. In particular, the temperature of the meshing portion of the drive gear 35 and the gear 25 rises to about 50 ° C. in the continuous operation, but the compressor 41 is constantly driven during the continuous operation of the motor 39, and the air passage from the cooler 40. By supplying cool air to the inside 27, a rise in the temperature of the dough F can be suppressed. Since the cool air supplied to the upper part of the ventilation path 27 flows around the supply pipe 22 and is discharged from below, the cool air always flows between the gear 25 which is a heat generating part and the supply pipe 22. In addition, the heat generated in the gear 25 is prevented from being transmitted to the dough F, and the generated heat is released to the outside. The temperature before the supply of the bread dough F is 10 ° C. to 15 ° C. However, even if continuous operation is performed while circulating cool air through the ventilation passage 27, the temperature rise such that the dough is burnt does not occur, and uniform and good quality is obtained. The product can be molded.
[0018]
FIG. 5 is a diagram showing another embodiment. In the embodiment of FIG. 2, the ventilation passage 27 is formed inside the mounting base 24, but in FIG. 5, the cylindrical outer cylinder 43 is concentrically arranged on the outer peripheral surface of the supply conduit 22, The ventilation path 27 is formed between the cylinder 43 and the supply pipe 22. An opening 44 is formed in the upper part of the outer cylinder 43, and the cooler 40 and the compressor 41 shown in FIG. The attachment base 24 is attached to a lower part of the outer cylinder 43.
[0019]
By attaching the outer cylinder 43 in this manner, a sufficient gap can be taken as the ventilation path 27, and the entire extruded portion 5 can be cooled.
[0020]
FIG. 6 is a diagram showing another embodiment. FIGS. 7 and 8 are cross-sectional views taken along planes AA and BB of FIG. 6, respectively. In this embodiment, the gear adapter 28 and the stirring adapter 29 in the embodiment shown in FIG. 2 are used as one adapter 28 to rotate the agitator 31, and the supply line 20 and the supply line 22 are replaced with the ventilation path 27. An air passage 45 is formed therebetween. As shown in FIG. 8, the ventilation passage 45 has a concentric void in a cylindrical tube 46 constituting the supply conduit 22. That is, the supply pipe 20, the ventilation path 45, and the supply pipe 22 are formed concentrically from the inside in this order. Cool air is supplied from one side of the air passage 45 from the upper side as in the above-described embodiment, flows through the air passage 45, and is then discharged from the opposite side of the air passage 45.
[0021]
Therefore, the cool air flowing through the ventilation passage 45 can cool both the inner material G in the supply pipe 20 and the outer skin material F in the supply pipe 22, and in particular, unless the temperature rise of the inner material G is suppressed. It is effective when it does not become. For example, when ice cream is supplied as the inner material G and rice cake is supplied as the outer material F, an increase in the temperature of the ice cream must be avoided. Although it is naturally necessary to lower the outside air temperature, it is very effective to form the ventilation path 45 as shown in FIG. 6 to flow cool air in order to avoid the influence of the heat generation in the drive transmission mechanism described above. It is.
[0022]
FIG. 9 is a diagram showing another embodiment. This embodiment is an apparatus for forming a twist cookie in which two types of cookie dough are intertwined. The two types of cookie dough are supplied from the left and right by vane pumps (not shown), similarly to the inner material G and the outer material F in FIG.

A nozzle support member 52 is rotatably fitted to a lower portion of the inner pipe 50, and a ring is fitted between the two to prevent the cookie dough from leaking. The nozzle 54 is attached to the nozzle support member 52. The mounting position of the nozzle 54 is located at a distance d from the central axis of the inner pipe 50. Therefore, when the nozzle support member 52 rotates inside the inner pipe 50, the nozzle 54 It turns on the circumference of radius d centering on the central axis. The cookie dough supplied from the left direction passes through the outer pipe 51 and is sent downward. The outer pipe 51 is arranged so as to be concentric with the inner pipe 50 as shown in FIG. Therefore, the cookie dough supplied from the left direction is fed downward through the gap between the inner pipe 50 and the outer pipe 51. A nozzle support member 53 is rotatably fitted to the lower part of the outer pipe 51, and a ring is fitted between the two to prevent the cookie dough from leaking. The nozzle 55 is attached to the nozzle support member 53. The mounting position of the nozzle 55 is located at a distance d from the central axis of the inner pipe 50.

The gear 58 is provided on the outer periphery thereof. As shown in FIG. 10, the gear 58 is driven to rotate by a drive transmission mechanism similar to the embodiment of FIG. Below the adapter 57, a cylindrical member 56 is vertically provided so as to surround the nozzle support member 53. A drive bar 61 connected to the nozzle support member 53 is fixed below the cylindrical member 56. Therefore, when the gear 58 rotates by driving the motor, the cylindrical member 56 attached to the adapter 57 rotates about the central axis of the inner pipe 50, and the nozzle support member 53 rotates following the rotation operation. Become. Therefore, the nozzles 54 and 55 rotate on the circumference of the radius d around the central axis of the inner pipe 50, and the cookie dough discharged from both nozzles are intertwined with each other alternately so that a string-shaped twist-type cookie dough is formed. Are continuously formed.
[0024]
Also in this embodiment, as in the above-described embodiment, heat is generated mainly at the meshing portion of the gear 58, so that the outer peripheral surface extending from the outer pipe 51 to the nozzle support member 53 and the inner peripheral surface extending from the adapter 57 to the cylindrical member 56 A ventilation path 60 is formed between the first and second surfaces to allow the cool air to flow in the same manner as in the above embodiment. The cool air flows in from the upper part of the ventilation path 60 from the compressor through the cooler, flows through the ventilation path 60, and is discharged from below. Therefore, similarly to the embodiment of FIG. 2, the influence of the heat generated by the adapter 57 on the cookie dough in the inner pipe 50 and the outer pipe 51 is suppressed, and the heat is released by cool air.
[0025]
FIG. 12 shows a modification of the embodiment of FIG. In FIG. 12, three nozzles 54, 55 and 70 are arranged on the lower surface of the nozzle support member 53 so as to be shifted by 120 degrees. The support member and the inner pipe for supporting the nozzle 70 are arranged in the outer pipe 51 as in the case of the nozzle 54. Also in this example, as the cylindrical member 56 rotates, the food materials discharged from the respective nozzles are alternately entangled and formed into a twisted food material in a string shape.
[0026]
FIG. 13 is an example of a food processing apparatus in which a string-shaped food is wound around a bar formed by discharging and shaping the two types of food shown in FIG. An inner nozzle 71 and an outer nozzle 72 similar to the nozzles shown in FIG. 2 are arranged concentrically inside the outer cylinder member 73. The outer cylinder member 73 is connected to a cylindrical member 74 similar to the cylindrical member shown in FIG. FIG. 14 is a view of the portion of FIG. 13 where the food is discharged, as viewed from below, and a ring-shaped nozzle member 77 for closing the space between the outer nozzle 72 and the outer nozzle 72 is attached to the discharge port of the outer cylinder member 73.
