CONSTITUTION:A constant amount of the finely cut flakes of dried bonito 1 is taken out from the quantitative feeder 3 consisting of the pressing member 8, the raking roller 9, the reversely raking roller 10, etc., the flakes are loosened by the loosening member 4 so that they are not entangled one another, the loosened flakes of dried bonito 1 are scattered in air by the dispersing member 5, and dropped on the moving conveyor 6. The flakes of dried bonito thus dispersed into a proper width in a uniform thickness, being transported by the conveyor 6, is pressed by the pressing member 7, so that the flakes of dried bonito are bonded to one another and molded into a sheet with about <=1mm. thickness. Consequently, thin sheets of flakes of dried bonito having bond strength, improved suppleness, and uniform thickness can be prepared efficiently.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method and apparatus for producing a sheet of dried bonito flakes, in which dried bonito flakes obtained by cutting fish flakes such as bonito flakes and mackerel flakes are bound together and formed into a thin sheet of approximately 1 mm or less. Regarding.

The inventors of the present application have previously developed various methods for manufacturing this type of dried bonito sheet. As one example, as shown in Fig. 1, bonito flakes B are dispersed on a flat plate material A, plate material A is placed on top of that, and bonito flakes B are sandwiched between both plates A. There is a method in which pressure is applied to pinch and press the cut knots.

In this case, to disperse the dried bonito flakes onto a flat plate, the dried bonito flakes are scattered by hand, or the dried bonito flakes are dropped from a vibrating conveyor or chute.

However, this method is inefficient, and it is difficult to distribute the shavings to a uniform thickness over the entire plate material, so the pressure-formed shavings sheet has thick and thin parts, and cracks can form between the two, or the shavings may split or break from those parts. The problem was that it was easier to do.

In addition, simply scattering bonito flakes 1 does not loosen the intertwined bonito flakes, so the bonito flakes fall onto the machining board material that has become intertwined and shaped into a lump, and as a result, a thick part is formed in the pressure-formed bonito sheet. However, there are disadvantages in that thin portions are formed and the thickness of the entire sheet is non-uniform, and furthermore, it tends to tear or break at the boundary between the thick and thin portions.

Also, when kebutushi comrades are intertwined, the surfaces of the kebutushi will overlap (
As a result, the pressure-formed bonito sheet becomes less flexible and tends to break when wrapped around food, and the binding strength of the bonito flakes becomes insufficient, resulting in insufficient bonding between the bonito flakes. There is also the problem that the bonito sheet becomes weak and tends to collapse and separate when added to the stock.

In addition, the conventional manufacturing method is to pressure-form the shavings B dispersed in the plate material A, so in order to mass produce it, as shown in Figure 1, a large number of plates A with the shavings B dispersed therein are laminated. There is also the problem that the work is troublesome and production efficiency is low.

The present invention is intended to eliminate these drawbacks. The present invention will be explained in detail below based on the drawings.

What is shown in FIG. 2 shows an example of the present invention. In the embodiment shown in FIG. 2, small pieces of dried bonito l are supplied to the hood 2, taken out in fixed amounts by a fixed quantity feeder 3, and loosened by a loosening body 4 to prevent the shavings from getting entangled with each other. The peeled bonito flakes 1 are scattered in the air by the dispersion body 5 and dropped onto the moving transport body 6 either naturally or forcibly using an appropriate suction device (not shown), and the dried knots 1 are appropriately deposited onto the transport body 6. The shavings are dispersed with uniform pressure over a wide area, and the shavings transferred by the transfer body 6 are pressurized by the pressurizing body 7 to bind the shavings together and form them into a sheet with a thickness of about 1 mm or less. It was designed to do so.

The quantitative supply body 3 is composed of a suppressor 8, a scraping roller 9, and a scraping back roller IO.

The pressing body 8 presses the stubble l that has adhered to the circumferential surface of the scraping roller 9 as it rotates between both rollers 9 and 10 with a constant pressure.

This fixed quantity supply body 3 locks the shavings l sent out near the scraping roller 9 with small protrusions 11 such as wire brushes planted on the circumferential surface of the roller 9, and then rotates the roller 9. It is lifted upward, and at this time, the presser 8 presses the cut pieces 1 with a predetermined pressure to make the density of the cut pieces l held between the small protrusions 11 almost constant. At this time, the scraps sealed on the circumferential surface of the scraping roller 9 are scraped off by the small protrusions 12 (wire brush, etc.) of the scraping roller 10 rotating in the same direction as the scraping roller 9. This is done so that the amount of cutoff l sent out from between .10 and 10 is always constant.

As the dispersion body 5, a Winnowa with blades 13, a blower, or the like is used.

What is shown in FIG. 3 shows another example of the present invention. In the embodiment shown in FIG. 3, the shavings l formed into small mounds are supplied to a fixed quantity supply unit 3 such as a compressed raw material feeder that supplies a fixed amount of the shavings l, and then the shavings l are supplied. i1 is dispersed in the air while being loosened by a dispersion body 5, and is caused to fall naturally or forcibly onto a moving transport body 6.

The quantitative supply body 3 shown in FIG. 3 has two belt conveyors 14 facing each other, and the interval between the two conveyors 14 on the exit side is narrowed.
The shavings passing between both belt conveyors are gradually compressed,
As a result, the aerodynamic force contained inside the cut knots is removed and the bulk density increases, so that the amount of cut knots 1 delivered from the fixed quantity supply body 4 becomes constant.

What is shown in FIG. 4 shows yet another example of the present invention. In the embodiment shown in FIG. 4, shavings cut into small pieces are supplied to a constant quantity supply unit 3 such as a supply hood that supplies a constant amount, and the shavings 1 supplied from this constant supply unit 3 is supplied to a dispersion body 6, and this The cut knots 1 are loosened by the dispersing body 6 and scattered in the air, and then dropped onto the moving conveying body 6.

The dispersion body 6 shown in FIGS. 3 and 4 is similar to that shown in FIG. 2, and has a large number of pins 13 protruding from the outer periphery of the roll. In FIGS. 3 and 4, 15 is a hood.

In the case of FIGS. 3 and 4 as well, the cut knots l dropped onto the transfer body 6 are pressurized by a rotating pressurizing body (not shown) to bind the cut knots together and form them into a sheet.

The pressurizing body 7 that presses the cut knots may be selected appropriately, and its -
As an example, the one shown in FIG. 2 uses rotating rollers, which are arranged above and below the conveying body 6. The other side of the pressurizing body 7 shown in FIG. 5 has pressing bodies 16 and 17 that are vertically movable facing the transfer body 6. This pressing body 16, 17 may be rotated while moving in the moving direction of the transfer body 6 as shown by the arrow in the figure, or may be simply moved up and down at a fixed position.

It is desirable that the surface of the shaved bonito l used in the present invention be as smooth as possible, and as shown in FIG.
It is preferable that the scraped piece 20 cut along the 9 direction (the x-lx force direction in FIG. 6) is further slightly changed to be elongated in the direction of the muscle fibers 19.

Since the method for manufacturing a cut-button sheet of the present invention is performed as described above, it has various effects as described below.

(1) Since the shavings are supplied from the quantitative supply device 3, the shavings fall onto the transfer body 6! The amount of fft is always constant. Therefore, since the amount of cut knots 1 dispersed in the conveying body 6 is constant, the cut knot sheet to be formed has a uniform thickness.

(2) Since the cut knots 1 are loosened into small pieces so that the cut knots do not get entangled with each other, or are scattered in the air and dropped while being loosened, the cut knots are dispersed on the conveying body 7 in a uniform thickness. be done. Therefore, it is less likely that the sheet will break or tear at the boundary between thick and thin parts as in conventional cut-button sheets.

(3) Since the shavings falling on the conveying body do not intertwine with each other, the shavings on the transporting body 6 are not vertically oriented, but are reliably oriented horizontally, so that the shavings that fall later on top of the shavings that fell first The surfaces overlap one another (surface overlap). Therefore, the cut knots do not break during pressurization and powder does not come out, so it is possible to produce a cut knot sheet with strong binding strength.

(4) Since the cut knots do not intertwine with each other, the cut knots falling onto the transfer body 6 do not form into lumps, and therefore the cut knots on the transfer body 6 do not become uneven, so that it is possible to obtain a cut knot sheet with uniform pressure.

(5) Since the bonito flakes are scattered in the air and dropped, the bonito flakes can be dispersed extremely thinly on the transporting body 6;
Moreover, since it can be finely dispersed, it is possible to obtain a highly flexible shavings sheet. Also, considering how thin it is, it doesn't have any holes.

(6) Since the shavings 1 are scattered in the air and dropped onto the moving transport body 6, the shavings 1 to be scattered are
By making the amount constant and the moving speed of the transfer body 6 constant, the amount of cut knots 1 dispersed on the transfer body 6 becomes constant. Also, as shown in FIG. 7, some of the dispersed scrapes 111i1 are blown far and others are not blown far, and the former fall in front of the conveying body 6, while the latter Since they fall from the forward side of the transport body 6, the cutlets distributed on the transport body 6 form layers, and the stacked state of the layers is such that those that do not fly far are on the bottom, and those that travel far are on the top. Since this condition is the same for all the positions of the cut knots distributed on the conveying body 6, it is possible to obtain a cut knot sheet of uniform quality in which the distribution of the cut knots is constant.

(7) Since the shavings 1 are scattered in the air and dropped onto the transport body 6, the powder mixed in the shavings 11 is not concentrated in one place but is uniformly dispersed throughout the transport body.

Therefore, unlike conventional manufacturing methods, the powder does not concentrate in one place, making it difficult for the cut knots in that area to bind to each other and weakening the binding force of the cut knot sheet.

(8) If a smooth surface is used as the shavings l, the shavings that are scattered and falling will surface polymerize, which will improve the binding of the shavings together, resulting in a flexible shavings sheet.

(9) As shown in FIG. 6, if the muscle fibers of the fish flakes 18 are cut into long strips along the direction IMI19, the muscle fibers of the fish flakes 18 will be scattered in the air and fall onto the transport body 6. l119
Since the directions are 380 degrees random, the molded cut knot sheet has strong strength in any 360 degree direction.

(io) The bonito production apparatus of the present invention includes a quantitative supply device 3 for supplying a fixed amount of cut bonito 1 to be cut;
a dispersing body 4 that loosens the shavings supplied from the shavings body 4; a dispersing body 5 that scatters the shavings loosened by the shavings body 4; a transporting body 6 that receives and transfers the shavings falling from the air; Since it is composed of a pressurizing body 8 that pressurizes the shavings inside to bind the shavings together, the structure is simple and the shavings can be reliably and easily uniformly dispersed. Therefore, it is possible to form a hard-to-disintegrate sheet that has a uniform thickness, has strong binding strength, and is resistant to disintegration even when placed in a liquid such as broth.

(l l) Since the apparatus of the present invention applies pressure to the cut knots 1 being transferred to bind the cut knots together, the manufacturing efficiency is significantly improved compared to the conventional manufacturing method shown in FIG.
