JPS6012927A - Preparation of sheet of flakes of dried bonito - Google Patents

Abstract

PURPOSE:To prepare sheets of flakes of dried bonito having improved strength and flexibility, by pressurizing flakes of dried bonito being transported by a conveyor, by rotating pressing members so that the flakes of dried bonito are securely bonded even at low aggregate pressure. CONSTITUTION:The flakes 2 of dried bonito are dispersed directly or indirectly in a proper width onto the conveyor 1, and the flakes 2 of dried bonito being transported by the conveyor 1 are pressurized by the rotating pressing members 3 so that the flakes of dried bonito are bonded one another and molded into sheet. Namely, since the flakes of dried bonito are brought into contact with the rotating pressing members in a state of linear contact, sheets of flames of dried bonito having high bond strength can be obtained by weak pressing force, and the molded sheets of flakes of dried bonito have high quality free from variability of strength and flexibility. Since the flakes of dried bonito are pressurized by the rotating pressing members while being transported, production efficiency is extremely improved.

Description

[Detailed Description of the Invention] The present invention provides 1! This invention relates to a method for manufacturing a bonito sheet, in which bonito flakes obtained by cutting fish bonito such as g-bushi and mackerel bonito are bound together and formed into a thin sheet of about 1 mm or less.

The inventors of the present application have previously developed various methods for manufacturing this type of dried bonito sheet. One method is to disperse bonito flakes on a flat plate, place a plate on top of it, sandwich the bonito flakes between the two plates, and apply pressure to both plates to sandwich and press the bonito flakes. There is something I did. However, since this is a surface pressurization method in which flat plates are clamped and pressurized, there are various drawbacks as described below.

(a) The pressing force per unit area does not need to be so high, but since pressure is applied to the entire board at the same time,
Unless the total pressure applied to the entire board is quite strong, the bonding between the cut joints will be insufficient. Therefore, a pressurizing device with a large pressure is required, and a large space is required to install it, which further increases the equipment cost.

(b) If the dispersed knots have thick and thin parts, pressure will be stronger on the thicker parts than on the thinner parts, and insufficient pressure will be applied to the thinner parts, resulting in uneven binding of the formed sheet. Also, the thickness and strength of the entire sheet vary. Furthermore, cracks form at the boundary between the thick and thin parts of the sheet, making it more likely to warp or tear, resulting in poor strength and flexibility.

(c) These drawbacks are rare when the plate material is made of rubber or plastic, which is highly elastic and easily deformed (because the plate material deforms according to the unevenness of the cutting joint), but when the plate material is a metal plate such as aluminum or stainless steel, This is especially true for materials that have poor elasticity and are difficult to deform. In addition, in the case of metal plates, shavings tend to adhere when pressurized, so the formed shavings sheet may peel off from the metal plate.
If you forcefully peel it off, the sheet may tear or tear.

(d) Rubber plates and plastic plates have good removability, but they can stretch or deform when used for a long period of time, and when deformed, it becomes difficult to apply pressure uniformly to the entire dispersed stubble, so replace it with a new plate. It is not economical. In addition, since the elasticity deteriorates by the amount of elongation, it becomes difficult to apply pressure uniformly to the entire cut joint during pressure molding. In addition, since the pressure-formed sheet tends to adhere to the plate material, it becomes difficult to peel the sheet from the plate, and the sheet is likely to tear or tear when peeled off.

(e) Conventionally, when forming a sheet with a thickness of 0.5 mm or less using a comb board or a plastic board as the plate material, a pressure of about 100 kg/cm2 had to be applied for a long time of 20 to 30 minutes. During this process, the unique taste and aroma of bonito flakes are lost, making it impossible to obtain high-quality bonito flakes.

(f) Conventional molding methods involve sandwiching cut knots between plate materials and press-forming one sheet at a time or stacking a large number of sheets, so continuous molding is not possible and production efficiency is poor. It is also difficult to automate.

In order to solve these various difficulties, the present invention uses a rotating body to pressurize the cut knots using a line pressure, thereby making it possible to reliably bind the cut knots together even if the total pressure is low, and increasing the strength. This makes it possible to make a sheet with excellent flexibility and flexibility, and by applying pressure while transporting the dispersed shavings, it is possible to continuously form the shavings sheet and improve manufacturing efficiency. be. The present invention will be explained in detail below based on the drawings.

As an example of the present invention, the one shown in FIG.
While being transported by the transporting body 1, pressure is applied by the rotary pressurizing body 3 to bind the shaved rri 2 together and form it into a sheet shape with a thickness of about 1 mm or less.

The belt 4 of the transport body 1 is made of stainless steel, steel, or other suitable material.

The moving speed of the transporting body 1 and the rotational speed of the rotary pressurizing body 3 are set to be the same speed so that the cutting joints 2 of the transporting body 1 do not shift or come together when pressurized by the rotary pressurizing body 3. .

Although the rotary pressurizing body 3 in FIG. 1 is placed opposite the tote with the transfer body l in between, the rotary pressurizing body 3 may be provided only on the transfer body l as shown in FIG. . In this case, it is preferable to make the belt 4 thick so that at least the lower rotary pressurizing body 3 can support the cut knots on the belt 4 during pressurization.

The one shown in FIG. 3 has a plurality of rotating rolls 5 arranged in a horizontal direction as a rotating pressurizing body 3 on a transfer body 1, and several stages of plural rotating rolls 5 are provided on top of the rotating rolls 5. A rotating belt 7 is wound around the outer periphery of a guide roll 6 disposed on the outer periphery, and when the entire rotating roll 5 is pushed downward by a pressure device 8 such as an air cylinder or a hydraulic cylinder, the rotating belt 7 is pushed down, and the belt 7 rotates and presses the conveyor. The cut knots 2 on the l are pressurized.

The lower rotary pressurizing body 3 has a plurality of rotary rolls 5 arranged in a horizontal direction, and several stages of the plurality of rotary rolls 5 are provided thereon.

The rotating roll 5 may be made of metal, hard plastic, or other suitable material.

The rotating belt 7 constituting the second rotating pressurizing body 3 is also made of stainless steel, steel, plastic, or other suitable material. If this rotating belt 7 is too thick, when pressurizing the cut knots 2, the pressure will be dispersed and the cut knots 2 will not be able to be sufficiently pressed, similar to applying pressure with a flat plate, so it should be made as thin as possible. It is best to avoid this.

As shown in FIG. 4, the rotary pressurizing body 3 may be formed by simply arranging rotary rolls 5 in a row in the horizontal direction, or may be provided by arranging several rotary rolls 5 in a row as shown in FIG.

In FIGS. 2 to 5, reference numeral 9 denotes a support for supporting the rotating roll 5.

When the rotating rolls 5 are arranged horizontally as shown in Fig. 6,
The distance between the transport body l and the rotating roll 5 thereon is such that the distance between the transporting body l and the rotating roll 5 on it is the same as that of the rotating roll 5. It may be arranged so that it gradually narrows from the side toward the rotating roll 54 side in the forward direction of movement, and as the transfer of the cut W12 progresses, the pressure on that side becomes stronger and stronger.

In front of the rotating pressurizing body 3, as shown in FIG.
The preliminary pressurizing body 1O shown in FIG. 7 is a belt 12 provided around the outer periphery of a rotary roll 11 so as to be freely rotatable.

In this case, if the belt 12 is made of metal with good thermal conductivity and the rotating roll 11 is a heating roll capable of heating the belt 12, the pre-pressing body 10 also serves as a heating body for heating the cut knots 2. In this way, it is possible to heat the cut knots in advance and then pressurize the cut knots 2, thereby improving the pressing effect. The preliminary pressure body 10 and the heating body may be provided separately.

The cut knots 2 may be directly dispersed on the transfer body 1, but they may also be dispersed by placing a plate 13 on the transfer body 1 as shown in FIG.

A binder, seasoning, or other foods such as plum pulp, sesame, dried seaweed, etc. may be added to Katebushi 2, and these may be added before or after dispersing Katebushi 2. You may.

As the plate material 13, a metal plate, a plastic plate, a rubber plate, a combination of plastic and metal, a combination of plastic and rubber, etc. are used.

As described above, the present invention disperses the cuttings 1f12 on the transporting body l, and transfers the cuttings 2 transferred by the transporting body l to the rotating pressurizing body 3.
Since the shavings are pressed together and formed into a sheet shape, it has the following various effects.

(a) Since the cutting fries 2 and the rotary pressurizing body 3 are in a line contact state, the pressing force of the rotary pressurizing body 3 is concentrated on the portion that contacts the cutting knots 2. Therefore, if the pressing force is a turning force, the force applied to the cut knots 2 will be stronger than when pressing with a flat plate material, so a cut knot sheet with strong binding can be obtained with a weak pressing force. In addition, since pressure can be applied in a short time with a low pressure, it is possible to produce high-quality bonito flakes sheets without losing the unique flavor and aroma of bonito flakes.

(b) Since the bonito flakes 2 and the rotary pressurizing body 3 are in line contact, even if the dispersed bonito flakes have thick and thin parts, the entire bonito flakes are uniformly and pressure-pressed. The molded shavings sheet is of good quality with consistent strength and flexibility.

(c) Since sufficient pressure can be applied with a weak force, a compact pressurizing device can be used, which is economical and does not take up much space.

(d) Conventionally, it was difficult to manufacture a desirable cut-stub sheet using a metal plate, but with the present invention, pressure can be applied with a weak force and in a short time, so the rotary pressurizing body 3 and the conveying body l
A metal belt can be used as the belt.

Moreover, if they are made of metal, they will not easily deform, so they can always be molded in the same state, and they can be used for a long period of time, which is also economical.

(E) Since the rotary pressurizing body 3 pressurizes the cut knots 2 while transferring them, continuous production is possible, and production efficiency is significantly improved. It also becomes easier to automate.
