Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for producing a sasa-kamaboko, which is a kneaded product made from fish meat or the like.

[0002]

2. Description of the Related Art Sasa-kamaboko is manufactured by molding a paste made of fish meat or the like into a predetermined flat shape imitating the shape of a bamboo leaf, and then heating the paste. Japanese Patent Application Laid-Open No. 10-327818 discloses a heating technique for heating a bamboo bowl to generate Joule heat by energizing the bamboo bowl.

Conventionally, joule heating is used for preliminary heating, and bamboo heating is performed in a heating furnace, that is, a baking furnace using electricity or gas as a heat source, for finishing heating. By this finishing heating, the surface of the bamboo shoot is burnt and the inside is heated to a temperature at which the inside is commercialized.

[0004]

In order to perform the finishing heating in the baking furnace as described above, the sasa-kamaboko is heated by radiant heat using electricity or gas as a heat source. In order to heat up to the temperature, it is necessary to maintain the atmosphere temperature in the baking furnace at a higher temperature, for example, about 280 to 300 ° C. The temperature in the furnace is set to such a high temperature because the inside is heated by heat conduction from the surface of the bamboo grass, and it is necessary to have a temperature difference between the surface and the inside. Therefore, in order to perform the finishing heating, it is necessary to consider the time of heat conduction, and a relatively long time is required for the finishing heating.

If the finish temperature is increased in a short time by raising the ambient temperature, the interior will not reach the desired temperature even if the surface is burnt. For this reason, in the baking furnace, the interior is heated to a desired temperature for a relatively long time in the initial stage of finishing heating, and the heating temperature is increased in the final stage to impart a baking color. That is, the bamboo basket is transported in the baking furnace over a long period of time, and the temperature of the atmosphere varies depending on the position of the baking furnace.

However, in the finishing heating method using a baking furnace, it is not easy to add a baking color to the surface while heating the internal temperature to a desired temperature. It may be dark, it may not look good and it may not be baked, or there may be a phenomenon that the skin called swelling floats,
In order to increase the production yield of bamboo shoots, temperature control of the furnace is an important factor.

On the other hand, in order to produce a bamboo shell with good texture, it is preferable to make the elasticity or hardness of the heated bamboo shell appropriate and to reduce the thickness of the skin.
If the amount of moisture contained in the inside of the bamboo shell after manufacture becomes small or the skin becomes thick, the texture becomes worse. It has been found that the quality of such a texture greatly depends on the conditions of the finishing heating. In other words, if the time of the finishing heating in the baking furnace becomes longer, the skin becomes thicker, and the amount of moisture contained in the inside of the sasamakamaboko decreases due to an increase in the amount of water evaporation from the inside during the finishing heating. In any case, the elasticity of the bamboo grass is reduced, and the texture is reduced.

[0008] An object of the present invention is to make it possible to produce high quality bamboo bamboo shoots with excellent texture and good yield.

[0009]

According to the present invention, there is provided a method for producing a bamboo basket, comprising the steps of: forming a kneaded product into the shape of a bamboo basket;
A preheating step in which the formed bamboo basket is sandwiched between the electrodes for preheating and a current is applied to the bamboo basket to preheat by Joule heat, and the prebaked bamboo basket is heated in a heating atmosphere of a baking furnace. It is characterized by having a coloring step of heating and baking, and a finishing heating step of energizing the sasaboko with the colored bamboo sandwiched between the electrodes for finishing heating and finishing heating by Joule heat. And

[0010] In the method for producing a bamboo shoot of the present invention, the heating temperature of the bamboo shoot in the preheating step is 70 ° C or less,
The heating temperature of bamboo shoots in the finishing heating step is 75 ° C
It is characterized by the above.

In the method for producing a bamboo basket according to the present invention, in the preheating step, a primary heating step in which the bamboo basket is transported in a horizontal state while being energized and heated, and an energization while the bamboo basket is transported in a vertical state are performed. And a secondary heating step of heating to a temperature higher than the primary heating temperature.

In the present invention, in the coloring step, the surface of the bamboo shoot is mainly heated, and in the finishing step after the coloring step, the inside of the bamboo shoot is heated by Joule heat with the electrode sandwiching the bamboo shoot. Since the heating temperature is increased to the finishing temperature, the amount of water evaporation from the inside of the sasa-kamaboko can be reduced, and the skin of the sasa-kamaboko can be thinned. In addition, since the time of the coloring process can be shortened, the temperature control of the baking furnace and the like can be easily performed, and the occurrence of blistering, overbaking, and insufficient baking can be prevented, and the production yield of Sasa-kamaboko can be improved. .

[0013]

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a process chart showing a method for manufacturing a bamboo scallop according to an embodiment of the present invention. Sasamakamabo, a kneaded product, is made using a paste formed by raw fish meat or the like and grinding it with a crusher or the like. The paste-like bamboo shoot material is first formed into a bamboo shoot having a predetermined shape imitating bamboo leaves by a forming machine. Next, the bamboo shoots are transported to a preheating step having a primary heating step and a secondary heating step. In the primary heating and the secondary heating, the Sasa-kamaboko itself is energized with the Sasa-kamaboko sandwiched between the electrodes to generate Joule heat in the Sasa-kamaboko itself to heat the Sasa-kamaboko.

In the primary heating step, about 10 to 14 after molding is performed.
Approximately 35 pieces of paste-like bamboo bamboo material at a temperature of about ℃
Heat to about ℃, and in the secondary heating process
Hereinafter, for example, heating is performed to about 65 ° C. As a result of the preliminary heating step including the primary heating step and the secondary heating step, the bamboo grass is brought into a shape-retaining property, that is, a state where a predetermined shape can be maintained even in a subsequent heating step.

In the primary heating step, the bamboo bamboo bamboo taken out of the molding machine is transported while being sandwiched between the transporting electrodes in a horizontal state and energized. On the other hand, in the secondary heating step, after the posture of the bamboo grass is changed to the vertical state, the bamboo is transported while being sandwiched between the transporting electrodes and energized. Therefore, when the secondary heating process is completed, the bamboo shoots are transported in a vertical state, and the baking color is applied in the baking furnace of the coloring process with the posture as it is, so that the temperature conditions on both surfaces are uniform in the baking furnace. It becomes roasted color.

In the secondary heating step and the baking furnace, a skewer member is inserted in advance in the bamboo shell in the baking furnace, and the skewer member is vertically set by the skewer member. It is transported in the baking furnace.

The step of inserting the skewer member into the bamboo basket may be performed in the first heating step or before or in the second heating step.
As described above, if the bamboo basket is heated in the vertical state in the secondary heating step, it is preferable that the bamboo is inserted before the secondary heating step.

The coloring step is a step of applying a golden or fox-colored baking color to both sides of the bamboo bamboo basket, and is formed by a heater or heater using electricity or gas as a heat source while transporting the inside of the baking furnace by a conveyor. The surface is heated by radiant heat or the like in the heating atmosphere.

The coloring step using a baking oven is a step for coloring the surface of the bamboo basket after preheating, and does not perform a process of raising the internal temperature of the bamboo basket to a predetermined temperature.

The bamboo shoot with its surface burned is conveyed to the finishing heating step, and is energized while being sandwiched between the electrodes, generating Joule heat in the bamboo shoot and heated. In this finishing step, the bamboo shoots are heated by Joule heat so that the inside thereof is completely at a temperature of 75 ° C. or higher.

As described above, in the present invention, only the surface is colored in the baking furnace, and the finishing heating is performed by Joule heat. Conventionally, in a baking furnace for finishing heating, the inside of a bamboo basket was heated from the outside until the inside temperature reached a predetermined temperature of 75 ° C. or higher, and the surface was colored. On the other hand, in the present invention, since only the coloring of the surface is performed in the baking furnace, the temperature control of the baking furnace becomes easy, and the production yield can be increased without thickening or blistering of the skin. .

As described above, in the method of manufacturing a bamboo basket according to the present invention, in the baking furnace 50, only the surface of the bamboo basket W is colored, and there is no need to raise the internal temperature to the finishing heating temperature. Therefore, the length of the baking furnace 50 can be shortened to shorten the time required for coloring.

As described above, since the coloring time can be shortened, when a baking furnace is used as the finish heating as in the related art, a floating phenomenon of the skin called blistering may occur. However, such a floating phenomenon did not occur, and it was possible to greatly improve the production yield of Sasa-kamaboko.

Further, since the coloring time can be shortened, the skin of the bamboo shoot W after the pre-heating does not become thick, and the amount of water contained in the bamboo shoot can be prevented from decreasing. It becomes possible to maintain the texture of the kamaboko satisfactorily.

In particular, in the bamboo basket heated by the hot air or the like in the baking furnace 50, water evaporates from the inside. However, since the coloring time can be shortened, the amount of water evaporation can be reduced. However, the surface of the bamboo basket is covered by the electrode plates 66 and 67 at the time of finishing heating, and the water vapor reaching the surface of the bamboo basket is prevented from evaporating to the outside by the electrode plates 66 and 67, thereby increasing the power supply efficiency. Will be improved. In addition, if the finishing heating is performed immediately after the coloring step by the baking furnace 50 is completed, the electrode which is at a lower temperature than the bamboo shell in the early stage of the finishing heating comes into contact with the surface of the bamboo basket, so that the baking color is obtained. , And the optimal baking color can be maintained even in the finish heating.

Each of the above-described electrode plates 21 and
The surfaces of 8, 45, 66 and 67 may be covered with a water-permeable film so as to avoid direct contact between the electrode plate and the bamboo grass. The water-permeable film is, for example, cellophane, paper, cloth, or any thin film having the property of containing water such as a nonwoven fabric, and is usually a hydrophilic film, a water-absorbent film, or a water-retentive film. Various films and film materials referred to as such can be used.

The present invention is not limited to the above-described embodiment, and it goes without saying that various changes can be made without departing from the scope of the invention.

For example, the structure of the secondary heating device 40 shown in FIG. 5 may be the same as the structure of the finishing heating device 60 shown in FIG. In that case, the chain conveyor having the skewer holders 54 that support the skewer members 34 attached at predetermined intervals can be arranged so as to extend linearly from the secondary heating device 40 to the finishing heating device 60. However, the primary heating device 10, the secondary heating device 40, the baking furnace 50
In addition, the chain conveyor in the finishing heating device 60 may be arranged independently. In this case, the bamboo basket W after each step is replaced with the skewer member 34 by the chain conveyor in the next step. become.

[0050]

According to the present invention, in the baking furnace, only the surface of the bamboo basket is colored, and the entire interior of the bamboo basket is heated to a desired temperature while heating the interior mainly in the finishing heating step without heating the interior. As a result, it is possible to produce bamboo shoots with good yield without generating blisters or the like on the epidermis and without causing over-baking or under-baking.

The evaporation of water from the inside of the bamboo basket in the baking furnace can be suppressed, and the skin can be formed thin, so that a bamboo basket excellent in texture can be manufactured.

The finishing heating is performed by Joule heating by sandwiching the surface of the bamboo basket heated in the coloring step with the electrodes, so that the baking color formed in the coloring step before the finishing heating is not changed. In addition, the inside of the bamboo basket can be heated to a desired temperature, and the finishing heating efficiency can be increased.
