Description

The present invention relates to a food dough discharging apparatus for continuously discharging food dough such as confectionery and bread. More specifically, when manufacturing a food dough having a double or multiple structure such as an inner packaging material and an outer skin material, the rotational speed of the stirring body for stirring or fluidizing the food dough and the rotation outside nozzle for discharging the food dough The present invention relates to a multiple food dough discharging apparatus and method for making the rotational speed different.

For example, a food dough dispensing device used in a packaging machine for producing bread rolls, etc. has an outer cylinder part and an inner cylinder part arranged concentrically, and the inner packaging material such as sauce is supplied into the inner cylinder part, The outer skin material such as the cloth is supplied to the annular space portion between the outer cylinder portion and the inner cylinder portion. Then, a blade or a stirring rod is rotatably provided in the annular space portion, the outer skin material (bread dough) supplied to the annular space portion is stirred or fluidized, and the inner packaging material discharged from the inner nozzle is the outer skin material (bread dough). A double or multiple continuous rod-shaped food dough body coated concentrically is discharged from the outer nozzle (for example, Patent Documents 1 to 3).

In the multiple food dough discharging apparatus described in Patent Literature 1 to Patent Literature 3 and the like, in order to discharge the outer skin material from the narrowed annular space between the inner nozzle and the outer nozzle, the inner pressure of the outer skin material is increased. Need to be supplied. However, when the internal pressure is high, the skin material discharged from the nozzle portion is discharged in a wider state than the outer diameter of the discharge port of the outer nozzle. When the rod-like food dough discharged in this way is covered and cut by a cutting device provided below the discharge device, for example, with a plurality of cutter bodies capable of reciprocating, the covered food spreads in the lateral direction. This results in a low-profile product with a low appearance.

Although it is possible to reduce the outlet of the outer nozzle as a means for wrapping and cutting the food to be in a waist-high state, the internal pressure applied to the outer skin material in the annular space portion is further increased, and the drive system of the stirring body There are problems such as an increase in load applied to the outer periphery and leakage of the outer skin material from the annular space to the drive system.

In order to solve these problems, the present inventors have found that the expansion (thick deformation) of the discharged rod-shaped food dough body can be suppressed by rotating the rod-shaped food dough body while rotating the outer nozzle. As a specific means, an outer nozzle is screwed and integrated downstream of a rotating body provided with a stirring body, and the outer nozzle is rotatably provided together with the stirring body. And the rotating body provided with the stirring body and the outer nozzle is, for example, 30 r. p. The above problem could be solved by rotating at m. However, when the stirrer is rotated at the above speed, the outer skin material (bread dough) discharged from the nozzle part has an insufficient stirring action and is discharged in a state where the surface of the dough is rough. The encapsulated food has a problem that it becomes insufficiently expanded in the subsequent fermentation process and becomes a product having a poor appearance and texture.

Therefore, the rotational speed of the stirring body is suitable for stirring and fluidizing fermented dough such as bread dough, for example 150 r. p. When rotating at m, the surface of the food dough discharged from the outer nozzle is smoothly molded without roughening the skin, but the food dough is greatly shaken outside and does not enter the opening area formed by the cutter body of the enveloping cutting apparatus. In some cases, there was a technical contradiction that could not be cut. In addition, even when the food dough body can be cut by a cutting device, there is a problem that stable forming cannot be performed such as the twist of the cut surface of the food dough body is strong and the outer shell material is torn and the inner packaging material is leaked.

Moreover, the twist forming apparatus described in Patent Document 4 does not include the stirring body that stirs or fluidizes the food dough. Therefore, there is a problem that the pulsation is generated in the continuous rod-shaped food dough body to be discharged, and the weight of the encapsulated food is disturbed. Moreover, the food dough body to be discharged may have insufficient stirring action, or the surface of the dough may become rough, resulting in a product with poor appearance and texture. In view of this, it is possible to integrally provide the agitator with the rotating body provided with the outer nozzle, but the rotational speed of the outer nozzle for twist molding is, for example, 80 r. p. m or the like. However, the rotational speed of the stirring member is, for example, 150 r.p. when food dough such as bread dough is used for the outer skin as described above. p. m is suitable, and when food dough such as cookie dough is used for the outer skin material, for example, 20r. p. m is suitable. Therefore, the rotational speed of the stirrer and the rotational speed of the outer nozzle are greatly different, and the above problem has not been solved.

The present invention solves the above-mentioned problem (technical contradiction), and rotates an agitator suitable for stirring or fluidizing a food dough and an outer nozzle suitable for forming a discharged food dough Can be set to different speeds. Furthermore, the present invention provides a food dough discharging method and an apparatus thereof in which each of the rotations can be individually rotated.

The control motor and the separate control motor can be independently driven so that the rotation speeds of the non-rotating nozzle portions are different, and the agitator is fixed to the rotating gear body and the inner cylinder portion fixed. The annular space formed between the annular outer space and the annular space formed between the rotating outer nozzle portion having a rotational speed different from that of the rotating gear body and the fixed inner tube portion. It is a food dough discharging apparatus characterized by being arranged .

The rise in the internal pressure of the food dough at the portion can be suppressed, and the discharged food dough body can be prevented from expanding and expanding thicker than the outer diameter of the discharge port of the outer nozzle. Moreover, it can suppress that the load concerning the drive system of a stirring body increases, or a shell material leaks out to the said drive system from an annular space part.
