Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application: This invention relates to an apparatus that is effective for use in producing various powdered foods by passing raw material dough through a screw extruder. This invention relates to a feeding device for raw material dough, which is particularly useful when the raw material dough is produced by using a screw extruder in the food industry, where it is generally easy to form lumps, such as rice flour or spaghetti soup. It is something.

Conventional technology and problems to be solved: To explain about food products made from the raw material dough as described above, such as hi-ichifu, this food is different from general noodles and usually has a key moisture content of about 25% to 50%. In addition to raw rice flour, a mixed raw material is used, and sometimes it is heated with steam or the like.

For this reason, relatively large lumps tend to form,
With conventional means, it has been impossible to supply a uniform and uniform amount to the screw extrusion barrel.

Solution: Does this invention have the above-mentioned disadvantages? To solve this problem, a screw feeder for feeding the raw material dough is installed above the input port.
A rotating impeller device is used to stir and crush the raw material dough, and a capacitance type sensor (violet) is installed to sense the entire amount of raw material dough being processed by the rotary impeller, and the signal from this is used to control the "1 turn" of the screw feeder. By providing a control means, it is possible to practically supply a desired homogeneous and uniform amount through the cooperation of these elements.

Embodiment: 1 is a raw material dough feeding device according to the present invention, which is installed in a machine frame 2, and includes a specially carved screw feeder 3;
It consists of a pair of rotary impellers 4, 4' and a capacitive chamber type sensor 5. In this example, the screw feeder 3 has two screws 3' + -1' k s with different pitches.
Interruption at small intervals m k The place where they are placed in a line is shown f
``''C2 These screws are composed of a screw with a vane (sharp or thin blade) thread whose center part is omitted, and is fixed to the shaft with a support rod 6. Ru. For stability during rotation, the pair of rotary impellers 4, 4° are usually made up of at least one set of two blades spaced apart by 180°, but in this example So there are four pieces? The case where it is prepared is shown.

The shaft of the screw feeder is bearing in a straight line as shown in the figure, and the transmissions S are in separate cylinders (not shown).
The vine is rotated into a separate tube. The capacitive sensor 5 senses the amount of raw material dough applied to the rotary impeller,
This signal is applied to a screw feeder motor (not shown), thereby controlling the rotation of the feeder. 7 is an inlet (supply) port for raw material dough, which opens above the screw at the rear end of the screw feeder 30.

8 is the second input port n6 which opens directly below the rotary impeller device,
At the bottom is a supply port at the rear end of a screw extruder (not shown). Incidentally, conventionally known scraping blades are attached to key points on the shafts of the screw feeder and rotary impeller to scrape off the dough adhering to the screw and rotary impeller. For convenience, it is omitted in the figure.

The reason why the screw feeder has a special shape as shown above is that by doing so, it is possible to particularly effectively prevent the raw material dough from clumping while being transferred by the feeder, and it also prevents the dough from clumping at the interrupted part. This is because it has been found that the crushing of wood can also be carried out. However, it can be said that even if a screw blade-type screw of the same type is used, or a screw with a blade-shaped screw thread that does not have a central part is used, it will work equally well. Not even.

The device of the present invention operates and the raw material dough is input from the input lower.
Then, it is transferred to the right through the screw feeder 3, enters the chamber 9 containing the rotary impeller, and is stirred by passing through the impeller.

Shattered. During this time, f of the raw material dough in the same room is sensor 5.
As a result, the rotation of the feeder 3 is controlled by this signal, and as a result, the amount of raw dough processed by the impeller is always a constant amount without any shortage. It will be fed into the screw extrusion barrel through the feed port 8. That is, as a result, the products produced from the extruder are always homogeneous and of good quality in equal quantities.

Effects of the invention: According to the present invention, as described in the proverb, by the functions of the screw feeder, rotary impeller, and sensor, a product of unprecedented homogeneity and uniform quantity can be obtained, and the screw feeder and rotary impeller are in line with each other. Since they are normally rotated at different rotational speeds around the axis of arrangement, the entire device can be made smaller and simpler. In addition, the device of the present invention has a powder frame body of 7:9r? Needless to say, by appropriately sealing the device, it can be easily operated even in a vacuum.
