Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an extrusion manufacturing apparatus for confectionery and the like, and particularly to an extrusion manufacturing apparatus for manufacturing puffed snack foods by pressurizing and heating flour or grains, alphaning the starch, and extrusion molding. This invention relates to an extrusion molding manufacturing device for confectionery, etc., which has a router device.

The extruder device extrudes flour or grains by pressurizing and heating the flour or grains to which a certain amount of moisture has been added.

After alphaning the starch and making it into a uniform paste,
By injecting the paste from the nozzle of a die under atmospheric pressure, the paste is rapidly depressurized and foamed, expanding 10 to 11 times.

In this case, even if the nozzle is configured to have a regular polygonal shape, the expansion coefficient is large, so the corners will not be clearly visible and the cross section will be close to circular, making it difficult to extrude confectionery with the desired shape. was difficult.

Furthermore, even if a shaping nozzle plate is provided at the front of the nozzle, and an opening of a desired shape is provided in this shaping nozzle plate and an attempt is made to shape the nozzle during the expansion process, the same angles will not clearly appear, resulting in a polygonal cross section. is extremely difficult.

In view of these circumstances, the present invention provides a product confectionery with a desired polygonal cross section when producing puff snack foods using an extruder device, thereby specifying the shape of the product. This is a molding manufacturing device that sequentially pressurizes and heats flour or grains and extrudes them through a nozzle of a die to form a predetermined shape. A confectionery characterized in that the confectionery to be extruded has a polygonal cross section by arranging a shaping plate having a polygonal opening facing the nozzle at the front of the die. Extrusion molding manufacturing equipment such as

Hereinafter, the present invention will be described in detail based on embodiments shown in the accompanying drawings.

FIG. 1 shows the main parts of the extrusion molding manufacturing apparatus according to the present invention, in which 1 is a transfer tube, 2 is a wire rod driven within the transfer tube 1, and 3 is a wire rod formed around the wire rod. 5 is a drive shaft 6 that rotationally drives the wire rod 2, is the machine body, I is a hopper connection tube, 8 is a die attached to the tip of the transfer tube 1, 4 is a nozzle formed on the die 8, 9 is a shaping board.

The nozzle 4 formed in the die 8 is formed by a group of slits arranged radially from the center at approximately equal opening angles from the center of the front surface of the die 8. For example, as shown in FIG. Four slits of equal size 4 a t 4 b , 4
c and 4 d extend in all directions at an opening angle of 90 degrees, forming a cross shape.

The center of the cross shape is located approximately on the extension of the gap 3, and the die 8 is provided with a plurality of cross nozzles 4 along the circumferential gap 3. .

As shown in FIG. 1, the shaping plate 9 is fitted and fixed with poles 11, 11 to cover the front surface of the die 8, and the shaping plate 9 has the die 8 as shown in FIG. An opening 10 having a square cross section is formed at a position facing the nozzle 4 of 8.

The size of this opening 10 is approximately the same as the shape and size of the extruded material extruded from the nozzle 4 when it is foamed and expanded to the maximum extent. The same dimensions are drilled through the wall thickness of the panel 9 from the front side to the rear side.

The thickness of the shaping plate 9 is sufficient for the extruded material extruded from the nozzle 4 to complete the foaming process within the openings 10, but this thickness is limited depending on the material of the extruded material. Some differences may occur depending on the adjustment of the selected water content, the extrusion speed from the nozzle 4, etc.

When puff snacks are manufactured using the extrusion molding manufacturing apparatus configured as described above, first, flour or the like that has been humidified at a constant rate (for example, 14 to 15%) is supplied from the hopper connection tube 7 into the transfer tube 1. By operating the drive shaft 5, the feeding action of the wire rod 2, which rotates, pushes out the flour, etc. in the direction of the die 8.

In this case, the flour, etc. advances in the transfer tube 1 heated to 140°C to 200°C while being pressurized through the gap 3 around the outer periphery of the wire rod 2, but due to this heating and pressurizing action, the starch of the flour becomes alpha. The pregelatinized grain flour is forced out of the cross-shaped slits of the nozzle 4 under atmospheric pressure and simultaneously fed into the openings 10 of the shaping plate 9.

When it is extruded from the nozzle 4, it has a cross shape that is approximately the same as the shape of the nozzle 4, but due to the sudden pressure reduction, it immediately begins to foam within the opening 10, and as shown in FIG. The cross shape continues to expand sequentially over time, and eventually expands approximately 10 to 11 times to have a substantially square cross section. It is approximately the same as the opening 10.

In addition, since the extruded material immediately foams due to the reduced pressure, the foaming process is almost completed and its shape is determined while it passes through the openings 10 of the shaping plate 9, so the expanded puff snack is constrained by the shape of the openings 10. In addition to the fact that the shape becomes a clear rectangular shape,
The puff snacks taken out from the shaping plate 9 are held in a straight line because foaming has already stopped within the openings 10.

Furthermore, the steam generated when the extruded material extruded from the nozzle 4 expands does not immediately diffuse to the outside, but stays in the openings 10 of the shaping plate 9 for a short time, so due to the influence of this steam, The surface of the extruded product becomes smooth, improving the quality of confectionery.

When the extrusion molding operation is performed continuously in this manner, a continuous rod-shaped expanded body is sent out from the opening 10 of the shaping plate 9.

Therefore, when the expanded body starts to extend to a certain size, a cutter for cutting it into pieces can be installed on the external front surface of the shaping plate 9 to cut the product confectionery into a predetermined length.

In FIG. 4, the nozzle 4 has a Y-shape, and consists of three slit groups 4e, 4f, and 4g extending radially at an opening angle of 120 degrees from the center and having equal lengths.

Therefore, the initial cross-sectional shape of the confectionery extruded from this nozzle 4 is approximately Y-shaped, but as a result of continued expansion in the same manner as in the above-mentioned embodiment, the confectionery finally has an equilateral triangular cross-section as shown in FIG. This led to the presentation.

In FIGS. 6 and 7, the shape of the nozzle 4 is
It consists of a group of 5 or 6 slits extending from the center at equal opening angles and equal lengths, and the confectionery extruded from this nozzle 4 ultimately becomes a regular pentagon or a regular hexagon.

Further, the shape of the aperture 10 in the shaping plate 9 is different depending on the shape of each nozzle made up of the above-mentioned slit group, and when the shape of the nozzle 4 is Y-shaped, the aperture 10 has an equilateral triangular cross section. When the shape of the nozzle 4 is composed of five or six slit groups, the nozzle 4 has regular pentagonal or regular hexagonal openings 10, respectively.

In addition, in the above-described embodiments of the present invention, the extruder device is used only for flour or grains, and is a mixed raw material consisting of grains and seafood such as squid shredded into 10 to 20 mesh pieces. It cannot be used for puffing because it requires a few kneading steps.

For this reason, the distance between the screw of the wire rod 2 and the inner wall of the transfer tube 1 is set to about 1.3 mm, and a groove having a spiral opposite to that of the screw is formed in the inner wall of the transfer tube 1. If the transfer time up to 4 is set to 2 to 3 seconds, it becomes possible to puff the mixed raw materials as described above.

As explained above, according to the extrusion molding manufacturing apparatus according to the present invention, the nozzle is configured with a plurality of slit groups arranged radially, and the front surface of the nozzle is provided with the extruded material extruded from the nozzle. A shaping plate having a polygonal opening approximately the same as the polygonal cross section after foaming of the object is arranged, and the foaming process of the extruded object can be completed within this opening.
In addition to making it possible to easily produce puffed snack foods with a polygonal cross-sectional shape, which has been considered difficult in the past, it is also possible to hold the extruded material in a straight line as it is extruded from the shaping plate, and it is also possible to Since the surface of the product can be formed smoothly by the action of the emitted steam, the product value as a puff snack food can be increased.
