Furthermore, the configuration of the food material mixing device according to the present invention is such that a mixing machine is installed in a cylinder having an intake port and an output port, and a kneading screw rotated by a drive source, and the intake port and the intake port are connected. It consists of a return path and a directional control valve interposed in the return path.

[Explanation of Examples]

Next, one embodiment of the present invention will be described based on the drawings.

FIG. 1 is a diagram showing an embodiment of a food material kneading device according to the present invention.

In the figure, 1 is a kneading machine, which is composed of a cylinder 2 and a mixed screw 4 rotated by a motor 3 as a driving source. One end of the cylinder 2 is provided with an intake port 2b serving as a first position where a hopper 2a is mounted, and an outlet port 2C serving as a second position is provided at the other end. A kneading screw 4 is rotatably housed in the hollow portion 2d of the cylinder 2, and is rotated at a constant speed by a motor 3 via a shaft 4a.

The mixing screw 4 has a pushing fin 4 near the intake port 2b.
b, and a fractured portion 4C is formed in the portion following this. Further, the distal end side of the crushing portion 4C is formed to be slightly constricted, thereby defining a discharge portion 2e within the cylinder 2.

The outlet 2C at the bottom of the discharge section 2e and the hopper 2a
It is connected to the intake port 2b equipped with a return pipe 5 through a return pipe 5. A three-way switching valve 6 is interposed in this return conduit 5. The main boat 6a of the three-way switching valve 6 is the outlet 2
The first branch boat 6b is connected to one end of the relay pipe 5b, and the second branch boat 6C is connected to one end of the exhaust pipe 7. The other end of the relay pipe 5b is connected to the inlet of a feedback pump 8 operated by receiving the driving force of a feedback motor 8a, and the outlet of this feedback bonder 8 is connected to a feedback pipe W5c.

Note that the return pipe line 5 is composed of a guide pipe 5a, a relay pipe 5b, a return pump 8, and a return pipe 5C.

First, when a predetermined amount of food material is put into the hopper 2aK, the food material is gradually taken into the cylinder 2 through the intake port 2b by the rotation of the screw 4 and pushed in the direction of the arrow in the figure. During this time, the rotating pushing fins 4b
After the food material is slightly crushed and kneaded, it is further crushed in the crushing section 4C of the mixing screw 4, and then sent to the discharge section 2.
You can push it out with et.

Now, the main boat 6a of the three-way switching valve 6 and the first branch boat 6
b is maintained in a communicating state, the food material in the discharge part 2e is taken out from the outlet 2C.

It is introduced into the relay pipe 5I) via the guide pipe 5a, the main boat 6a, and the first branch boat 6b, and then is fed to the kneading machine 1 via the return pipe 5C after receiving the pumping force from the return pump 8.

Here again, the food material is crushed and kneaded while being extruded within the cylinder 2, and the above steps are repeated.

When the degree of kneading of the food material matches the target degree, when the main port 6a of the three-way switching valve 6 and the second branch bow 6C are switched manually or electromagnetically to communicate with each other, the cylinder 2
All the food materials inside are extruded to the outside at once through the exhaust pipe 7 in a batch manner.

In this way, the crushing and mixing process inside the cylinder can be automatically repeated many times, so food materials with a kneading level lower than the desired level will never be discharged to the outside, and the process will always be accurate. By selecting the degree of kneading, and by selecting the number of repetitions, it is possible to respond appropriately to cases where the type and condition of the food material and the environmental condition are different.

Furthermore, according to the apparatus of the above embodiment, since the food material can be automatically circulated, the length of the kneading screw 4 can be relatively short, and the driving force of the motor 3 can also be relatively small, so that the entire apparatus can be It becomes compact.

The food material is automatically circulated by the pushing force generated by the rotation of the cross-contact screw 4, and in the above embodiment, the discharge force of the feedback pump 8 assists in this, so that the food material is circulated quickly and smoothly.

Although the kneading machine 1 in the above embodiment uses a single-axis kneading screw 4, the food mixing device according to the present invention is not limited to this, and may use two or more multi-axis screws. Further, a sensor for detecting the degree of kneading of the food may be provided in a part of the return pipe 5, and this sensor may be configured to be linked with the three-way switching valve 6.
