Description

  The present invention relates to a food battering apparatus that forms a grille on the food surface of sushi, for example.

  For example, in the case of ingredients such as fish fillets that are served as sushi as food, especially ingredients with a lot of fat, when you put them in your mouth, enjoy the flavor of the ingredients when they are baked For this reason, the surface of the material is crushed using a gas burner or the like so as to make a grill. When putting a grille on the ingredient surface, it is necessary to put a grille only on the ingredient surface while keeping the raw state, and a high degree of skill is required for curling the ingredient.

  Especially in the form of sushi sales such as carousel sushi, many of the sushi workers have very low level of skill as sushi chefs, so it is difficult to put a grill on only the surface of the ingredients. Has the problem of losing its commercial value as sushi.

  In addition, gas burners are used in many cases in the processing of ingredients, but when the ingredients surface is beaten, the ingredients are likely to have a gas odor, and thus a gas odor is attached. When eating sushi, it has the problem of causing olfactory discomfort.

  As a prior art of the present invention, for example, a turning device shown in Patent Document 1 is known. The turning apparatus has a transfer conveyor for placing a suitably shaped piece of iron or the like arranged in one direction, and the transfer for the fly where at least the width of the conveyor is a flame width below a predetermined position that becomes a turning area of the transfer conveyor for turning. The conveyor is arranged orthogonally, and an ignition burner is attached to the front side of the orthogonal position of the soot conveying conveyor, and a flame reflector is provided above the soaking area of the soaking conveyor, and placed on the soot conveying conveyor. It is assumed that the width of the conveying conveyor for crossing passes through the width of the conveyor width flame that has burned in the flame is changed to the lower side, and at the same time, the main flame passing through the conveying conveyor for forging is forcibly reversed by the flame reflector and the upper side is also turned. Configured.

  The turning device is provided with a reflecting plate provided in the turning area while turning the underside of the turning material by the fired iron carried by the carrying conveyor for the turning material conveyed by the turning conveyance conveyor. By reflecting the flame mainstream and hitting the upper side of the covering material, the entire covering material is covered.

In the apparatus, the degree of squeezing is adjusted by the amount of koji and the conveyance time. However, in the food targeted by the present application, it is necessary to finely adjust the sieving degree. However, the above apparatus has a problem that it cannot be used for the purpose of baking the food targeted by the present application because fine adjustment is extremely difficult. Moreover, in the said apparatus, since the conveyance conveyor for roasting, the conveyance conveyor for cocoons, and a reflector are made into an essential structure, while the apparatus itself enlarges, it has the problem which cannot be used in a shop.

  The problem to be solved is that a high level of skill is required to make a grill on the surface of food. In addition, if a gas burner is used to make a grill on the surface of the food, the food will smell of gas and the quality will deteriorate. Furthermore, it is difficult to fine-tune the degree of roasting according to the type of food, and the desired roast is not possible.

  The present invention provides a food roasting device provided with a roasting means disposed in a roasting region and heating the surface of the food to make a grille, the roasting means comprising an integrating tube having an opening on the outer periphery facing the food, An infrared heater that is provided in the integrating tube and outputs infrared rays with a length that coincides at least with the longitudinal direction of the opening. The infrared ray that is output from the infrared heater through the opening to the food surface and the inner circumference of the integrating tube The most important feature is to form a burned line by irradiating infrared rays reflected from the surface and output from the opening.

  According to the present invention, even when the skill level of an operator is low, a grilling with a desired degree of rotting can be put on the surface of the food. In addition, it is possible to prevent the smell of the heat source from being added when making the grilled eyes, and to keep the food in high quality. Furthermore, the degree of resilience can be adjusted according to the type of food.

It is a whole perspective view of the sushi roasting apparatus which implemented the roasting apparatus. It is explanatory drawing which shows a turning means. FIG. 2 is a vertical sectional view taken along line AA in FIG. 1. It is an axial direction longitudinal cross-sectional view which shows the boiled state of foodstuffs. It is an axial orthogonal cross-sectional view which shows the irradiation state of the infrared rays with respect to foodstuffs, and the ventilation state of compressed air. It is explanatory drawing which shows the example of a change of a conveyance means. It is explanatory drawing which shows the example of irradiation change with respect to the surface of foodstuffs.

  The best mode is to form the grille by irradiating the surface of the food with the infrared ray output from the infrared heater through the opening and the infrared ray reflected from the inner peripheral surface of the integrating tube and output from the opening.

Hereinafter, the Example which implemented the food-brilling apparatus of this invention as a sushi-boiled apparatus which forms the grilling eyes by rolling the ingredients surface of sushi is demonstrated according to a figure.
As shown in FIG. 1 to FIG. 3, a sushi-buri apparatus 1 as a food-blowing apparatus 1 according to the present invention includes an endless transfer unit 5 that conveys sushi 3 as a food, and an upper part of a sushi area in the transfer unit 5. It is comprised by the turning means 7 provided in this.

  The transport means 5 has an axis in the transport orthogonal direction, a driven shaft 9 that is rotatably supported on the upper side or the lower side in the transport direction of the turning region, and an axis in the transport orthogonal direction, A drive shaft 13 that is rotatably supported on the opposite side of the driven shaft 9 and to which the electric motor 11 is drivingly connected, and a sprocket 9 a provided at least at the axial end of the driven shaft 9 and the drive shaft 13. It is comprised with the endless conveyance body 15 spanned to 13a.

  In order to prevent the heat from the above-described turning means 7 from accumulating as the transport body 15, a metal wire material such as stainless steel or a plastic wire material is knitted and connected endlessly, and at least the width in the transport orthogonal direction is transported. A net strip having a width equal to or greater than the width of the sushi 3 in the longitudinal direction is suitable. And the conveyance body 15 which consists of a net belt conveys and carries out the mesh | engagement of the teeth of the sprockets 9a and 13a with the mesh.

  The turning means 7 includes an integrating tube 17, two infrared heaters 19 disposed in the integrating tube 17, and a blowing member 21 that blows air into the integrating tube 17. The integrating tube 17 is made of a ceramic material with a small amount of heat dissipation, and the axial direction has a length corresponding to at least the rolling region, and has a width corresponding to at least the longitudinal direction width of the sushi 3 on the side facing the carrier 15. It is formed in a cylindrical tube with an opening 17a extending in the axial direction, and its inner peripheral surface is mirror-finished.

The openings at both ends in the axial direction of the integrating tube 17 are closed by a closing plate 17b such as a ceramic plate or a stainless plate whose inner surface is mirror-finished.

  The integrating tube 17 reflects infrared rays (including near-infrared rays and medium-wave infrared rays) output from an infrared heater 19 (described later) in a direction other than the opening 17 a on the inner peripheral surface, and is output from the infrared heater 19. The most infrared ray is output from the aperture 15a, and is based on the principle of an integrating sphere used to measure the total luminous flux of light output from the light source.

  The infrared heater 19 is disposed near the opening 17 a in the integrating tube 17, and the longitudinal direction corresponds to the axial length of the integrating tube 17. The infrared heater 19 has a structure in which a carbon filament and an inert gas are enclosed in a glass tube corresponding to the length in the axial direction of the integrating tube 17 and outputs near infrared rays and medium wave infrared rays.

In this embodiment, two infrared heaters 19 are used. However, the present invention is not limited to the number of infrared heaters 19. In addition, the infrared heater 19 of this embodiment efficiently outputs infrared rays in a direction perpendicular to the plane by forming the carbon filament with a required width and a folded surface. Further, as the infrared heater 19, one that outputs medium-wave infrared light with high thermal energy is suitable. On the other hand, when the infrared heater 19 outputs far-infrared light, the far-infrared light is applied to the ingredients 3 a of the sushi 3. The infrared heater 19 of the present invention is not desirable because it heats the whole through the inside.

  The blower member 21 is constituted by an electric blower or the like, and the compressed air by the blower member 21 is provided in the integrating tube 17 via a blower pipe 21a provided in one closing plate 17b so as to communicate with the inside of the integrating tube 17. And then discharged to the conveying body 15 side through the opening 17a. As a result, hot air heated by the infrared heater 19 in the integrating tube 17 is released to the carrier 15 side to promote the sag of the ingredient 3a.

  Next, the operation of the sushi making apparatus 1 configured as described above will be described. First, the sushi 3 is placed on the transport body 15 so that the ingredients 3a are located above and the longitudinal direction faces the transport direction. The electric motor 11 of the conveying means 5 is driven in a state where it is placed on the moving member 15 so that the conveying member 15 travels in the direction of the solid arrow shown in the figure, and a driving current is applied to the infrared heater 19.

  The infrared heater 19 generates heat at a high temperature (about 1000 ° C. or higher) and outputs infrared rays. Most of the infrared rays output from the infrared heater 19 are directly irradiated from the opening 17 a of the integrating tube 17 toward the carrier 15. Further, the remaining infrared light output from the infrared heater 19 into the integrating tube 17 is irradiated from the opening 17 a toward the carrier 15 while being repeatedly reflected on the inner peripheral surface of the integrating tube 17.

The integrating tube 17 increases the heating efficiency of the infrared heater 19 by irradiating the light output from the infrared heater 19 from the opening 17a by repeating reflection on the inner peripheral surface on the same principle as the integrating sphere as described above. ing.

As described above, the surface of the ingredients 3a of the sushi 3 conveyed by the traveling of the conveying body 15 is irradiated with infrared rays from the opening 17a for a time corresponding to the width in the conveying direction of the opening 17a and the conveying speed, and only the surface portion is irradiated. Form a grille. At this time, the compressed air supplied into the integration tube 17 is jetted from the opening 17a to the surface of the ingredient 3a together with the air in the integration tube 17 heated by the infrared rays output from the infrared heater 19 and heated. Be promoted to be beaten. (See Figs. 4 and 5)

Further, when a burnt line is formed on the surface of the ingredient 3a by infrared rays irradiated from the opening 17a, the protein, lipid, etc. of the ingredient 3a are burned to generate smoke, and the generated smoke is jetted from the opening 17a. The compressed air from the blower member 21 increases the pressure in the integrating tube 17 and prevents the smoke from entering the integrating tube 17 by the air discharged from the opening 17a. As a result, the inner peripheral surface of the integrating tube 17 can be prevented from being contaminated, and the reflection efficiency of infrared rays output from the infrared heater 19 can be maintained.

Then, when the sushi 3 having a grilled surface formed on the surface of the ingredients 3a is conveyed to the carry-out side of the conveying means 5 through the groin region in the conveying means 5, the driving of the electric motor 11 is stopped and the conveyance is interrupted. Then, it is possible to take out the sushi 3 in which the grilled eyes are formed on the surface of the ingredients 3a from the conveying means 5.

In addition, a stacking device such as a roller conveyor (not shown) is inclined and arranged on the carry-out side of the transport means 5 so that the sushi 3 discharged and transferred from the carry-out means 5 is stacked on the roller conveyor. You may comprise. In this configuration, a grilled line can be formed on the surface of the ingredients 3a of the sushi 3 while the transport means 5 is continuously transported and driven.

Moreover, in order to change the surface curling degree according to the kind of ingredients 3a of the sushi 3, the current value applied to the infrared heater 19 is varied, or the conveyance speed of the sushi 3 by the conveying means 5 is varied. This can be adjusted arbitrarily.

In the above description, the transport means 5 has a configuration in which the net-like transport body 15 is stretched over the sprockets 9a and 13a respectively provided on the driven shaft 9 and the drive shaft 13 that are disposed at least at a position sandwiching the turning region. In the transport means 5, since the carry-in side and the carry-out side are separated from each other, a worker who puts the sushi 3 on the transport body 15 and a worker who takes out the sushi 3 on which the surface of the ingredients 3a is beaten are arranged. It was necessary and work efficiency was bad.

As the conveying means 51 of the present invention, as shown in FIG. 6, a conveying body 53 configured in a mesh disk shape is configured to rotate at a required speed in accordance with the driving of the electric motor 55, and the conveying body according to the turning area. The sushi mashing apparatus 1 may be configured by arranging the mashing means 7 above 53.

In the sushi making apparatus 1 provided with the conveying means 51, for example, an operator is placed at a position opposite to the rolling means 7 with respect to the center of the conveying body 53, and the sushi is placed on the conveying body 53 at the position. The work of transferring 3 and the work of taking out the sushi 3 on which the roasted eyes are formed according to the rotation of the carrier 53 can be efficiently performed by a single operator.

In the above explanation, the infrared rays reflected from the infrared heater 19 directly or from the inner peripheral surface of the integrating tube 17 are applied to the surface of the ingredients 3a of the sushi 3 conveyed by providing the infrared heater 19 in the integrating tube 17. However, in the present invention, as shown in FIG. 7, an optical lens 71 (the axial direction is a grille) between the infrared heater 19 and the ingredients 3a of the sushi 3 being conveyed. Are arranged so that the infrared rays output from the infrared heaters 19 extend in the conveyance orthogonal direction with respect to the ingredients 3a of the sushi 3 being conveyed. It may be configured to converge to form a grille.

In the embodiment shown in FIG. 7 as well, the infrared heater 19 is arranged in the integrating tube 17 and reflected on the inner peripheral surface of the integrating tube 17 together with the infrared light directly output from the infrared heater 19 through the opening 17a. The infrared rays output indirectly through the openings 17a may be converged so as to extend in the conveyance orthogonal direction by the optical lens 71 with respect to the surface of the material 3a, thereby forming a burned line.
