<Conventional technology> In general, in the production of cream korotsuke, first,
A white roux is prepared by heating and stirring oil and fat, and flour is heated and stirred, and raw materials such as meat and onions are heated and added to this, and these are further mixed, and milk is added and kneaded by heating. Next, the dough thus prepared is cooled to room temperature or below, molded into a certain shape, and then buttered and breaded to form a cream korotsuke. As a means for molding such cream crotches, a mechanical molding device is generally used that employs a mold filling and punching method.

<Problems to be Solved by the Invention> However, with such mechanical forming, the dough tends to be kneaded excessively, and the dough needs to be hardened to a certain extent to be suitable for mechanical dressing. There were problems such as high density due to kneading and molding pressure, and air bubbles during kneading, resulting in deterioration of quality.

This invention was made by focusing on such conventional problems, and it is possible to mold a high-quality fluid food that is creamy and does not contain air bubbles.

It is designed to be reciprocated by a reciprocating device 31 such as the following.

Next, the operation of this embodiment will be explained.

When molding a fluid food material, first, the supply section 20 of the quantitative filling device 19 is brought into a state where a sufficient amount of fluid food can be supplied, and then the mold circulation device 1 is
The transport conveyor 2 and the cooling conveyor 8 are driven. Of these, the transport conveyor 2 is driven as follows. That is, the piston 5b of the reciprocating device 5 is extended so that the sloped surface 7b of the bar operating member 7 at the tip thereof overcomes the mold moving bar 4, and is moved to the position indicated by the chain line in FIG.
Next, the piston 5b is contracted, and the bar operating member 7
The mold moving bar 4 is attracted to the vertical portion 7a of the mold moving bar 4. Next, by pulling back to the solid line position in the figure and repeating this operation, the conveyor 2 is moved along with the mold moving bar 4 to the conveyor pulley 3a,
3b, it can be circulated in the direction of arrow A. Further, at this time, the cooling conveyor 8 is placed between the conveyor pulleys 9 and 10 and circulates in the direction of arrow B, and this operation is substantially synchronized with the intermittent running of the conveyor 2. The cooling conveyor 8 performs an intermittent running operation in which it stops for a set time at a position where quantitative filling is performed by the quantitative filling device 19, and then runs again.

On the other hand, during the period when the transport conveyor 2 and the cooling conveyor 8 are stopped, the flange 15a of the mold 15 that has been pushed on the mold guide 18 by the mold moving bar 4 separates from the mold guide 18. Then, mold supply device 1
It is placed on the hook 14 of No. 3. For this reason,
By extending the piston 13a, the mold 15 is lowered to the chain line position as shown in FIG. After this mold 15 is placed on the cooling conveyor 8, by lowering the foot 14 slightly, the ridge 15a is separated from the hook 14, and the mold 15 is moved onto the cooling conveyor 8. It is placed on top and simultaneously conveyed in the direction of arrow B during the next intermittent movement.

On the other hand, a fixed amount of fluid food is injected from the nozzle 26b of the quantitative filling device 19 onto the mold 15 transported in this manner, and the food material inside the mold 15, which is cooled by the cooling tank 11, is Cool and solidify. In this way, the cooling conveyor 8
The mold 15 sent by the mold 15 reaches the mold release position. At this time, the mold release device 1
The piston 16a of No. 6 extends downward as shown by the chain line, and the protrusion 15a of the mold 15 is placed on a hook 17 connected thereto. Then, when the conveyors 2 and 8 are stopped, the piston 16a is retracted and lifted to the same state as shown by the solid line in FIG. 2, leaving only the molded and solidified food material on the cooling conveyor 8. The mold 15 is raised. Next, as the transport conveyor 2 continues to run, the mold moving bar 4 pushes the mold 15 supported on the hook 17 in the direction of arrow A, and releases it from the hook 17. Therefore, the mold 15 is now moved in the same direction on the mold guide 18 by the push of the mold moving bar 4, and reaches the mold moving position again. Here, the mold supply device 13 moves the mold 15 again, and the mold 15 is supplied onto the cooling conveyor 8. As a result, the mold 15 circulates between the lower part of the conveyor 2 and the upper part of the cooling conveyor 8.

On the other hand, the quantitative filling device 19 is located above the cooling conveyor 8, and the liquid food is placed in the mold 1.
5. Fill on top. This fixed-quantity filling device 19 molds the fluid food that is fed into the supply section 20 . Now, the rotary valve 21 is rotated by the motor 29, and as shown in FIG. 4, the passage opening 25a of the rotary valve 23 is communicated with the passage 26a of the valve case 24, and the passage opening 25c is communicated with the passage 26c. In this case, the communication passage 25, the supply section 20, and the cylinder 30a communicate with each other. Here, when the cylinder device 30 is actuated and the piston 30b is pulled within the cylinder 30a, the fluid food is transferred from the supply section 20 to the communication path 25 due to the intake negative pressure.
A fixed amount is then filled into the cylinder 30a.
Next, in this state, the valve 13 is rotated by the motor 29 to bring it into the state shown in FIG.
In this state, the passage 26a is closed and the passage opening 25b is closed.
communicates with the passage 26c, and the passage opening 25c communicates with the passage 26b, which is a filling nozzle. Here, when the cylinder device 30 is operated by the reciprocating device 31 and the piston 30b is pushed out of the cylinder 30a,
The filled fluid food is injected into the mold 15 shown in FIG. 1 from the filling nozzle serving as the passage 26b without undergoing any kneading operation, and is rapidly cooled and solidified in the cooling tank 11 as described above. do.
This prevents air bubbles from forming in the dough. Note that at this time, the shutter plate 2 of the shutter device 27
8 is left open and closed after a fixed amount of injection to prevent the dough from dripping from this passage 26b. Further, after the injection operation, while the mold 15 is moving on the cooling conveyor 8, the rotary valve 2 is moved by the motor 29.
3 is again set to the position shown in FIG. 4, and the piston 30b is pulled within the cylinder 30a to suck the fluid food into the communication passage 25 and the cylinder 30a again. In this way, it is possible to prepare for the next quantitative filling operation.

The conveyors 2 and 8, the mold supply device 13, the mold removal device 16, and the quantitative filling device 19 are controlled by a control system (not shown) at fixed operation timings in order to perform each of the above operations continuously and smoothly. Ru.

Furthermore, the above embodiments can also be applied to cooling and solidifying fluid foods such as cream korotsuke, chiyokolate, pudding, agar, and jelly sweets.

Further, the amount of fluid food filled by the quantitative filling device 19 can be arbitrarily set depending on the volume inside the cylinder 30a due to the insertion of the piston.

Furthermore, if a mold guide cover 40 as shown by the dotted line is provided at the portion where the piston 16a of the mold release device 16 moves up and down, the hook 1
7 to prevent the mold 15 from falling off.
You can lift it while guiding it.
