Description

  BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to a food roasting apparatus for baking only on the surface of various foods (including foodstuffs) such as fish (including sushi and sashimi), meat and breads.

  The applicant of the present invention transports the sushi on which the ingredients are placed on the upper portion to a predetermined rolling area by a conveying means as shown in Patent Document 1, and is provided in an integrating pipe having an opening at the outer periphery in the area. Infrared rays output from the infrared heater to the surface of the sushi material by an infrared heater unit provided with an infrared heater that outputs infrared rays from the opening and an infrared heater unit including a blower member that supplies compressed air into the integrating tube; We proposed a sushi roll device that forms baked spots by infrared rays that are reflected and emitted from the opening.

  The above-mentioned sushi roll device can effectively burn only the surface of ingredients even if the work proficiency is low, and it is effective to attach gas odor to ingredients compared to the case of using a gas burner. Although it can be prevented, a device is required because a large-sized integrating tube is provided which is spaced from the inner peripheral surface to accommodate the infrared heater and which reflects infrared radiation output from the infrared heater and outputs it from the opening. In addition to the increase in size itself, the integration tube itself absorbs heat energy at the time of reflection of infrared rays to cause a high temperature, and there is a risk that the worker will be burned.

Moreover, depending on the food, it may take time to bake the surface, but with the above-mentioned roasting device, it is difficult to easily adjust the irradiation time of infrared rays to the food, and it is possible to cope with the food. In addition, it was difficult to put the grilled eyes according to taste efficiently, and it was not possible to cope with various foods.

Furthermore, in the above-mentioned skewer, since the integrating pipe is fixedly provided to the conveying means, the height of the integrating pipe (infrared heater) should be changed according to the size (height) of the food. It was difficult to effectively put on the surface of the food effectively, and it was not possible to cope with various kinds of food.

  The problem to be solved is that since the large-sized integrating tube is required, the size of the device itself is increased and the temperature of the integrating tube itself is increased by the heat energy absorbed at the time of infrared reflection, and there is a risk that the operator may burn. It is at a certain point.

In addition, it is difficult to easily adjust the irradiation time of infrared rays to the food, it is difficult to cope with the food, and it is difficult to efficiently put the baked eye according to the taste, and it is impossible to cope with various foods. is there.

As shown in FIGS. 1 to 5, the food rotating apparatus 1 according to the present invention comprises a transport unit 5 as a transport unit for transporting the food 3 and an infrared heater unit 7 provided above the transport area of the transport unit 5. Be done. The food 3 to which the present invention is applied is, for example, fish (including sashimi), meats, breads and the like, which have a commercial value enhanced by being burnt only on the surface.

  The transport unit 5 is detachably attached to the main body 9, and the frame 11 of the transport unit 5 is rotatably supported by having an axis in the transport orthogonal direction on the upper side or the lower side in the transport direction. The driven shaft 13 has an axis in the conveyance orthogonal direction opposite to the driven shaft 13 (lower side or upper side in the conveying direction), and the axial end on the main body 9 side is protruded so as to be rotatable. A drive shaft 15 is supported by a shaft, and an endless carrier 17 is stretched around sprockets 13a and 15a provided at least at axial ends of the driven shaft 13 and the drive shaft 15.

  The transport body 17 transports a metal wire such as stainless steel or a heat resistant plastic wire at least in the transport orthogonal direction in order to prevent the heat from the infrared heater unit 7 from being accumulated. It is preferable to use a mesh band which is woven and endlessly connected to have a width equal to or greater than the width. The teeth of the sprockets 13a and 15a are meshed with the mesh on the meshed belt-like carrier 17 and travels in a predetermined direction as the drive shaft 15 rotates.

When the transport unit 5 is mounted on the main body 9, the shaft end of the drive shaft 15 is connected to the output shaft of the electric motor 19 mounted in the main body 9, for example, whose frequency of rotation is controlled. The transport body 17 is transported at a desired transport speed as the electric motor 19 is driven.

  In order to position the transport unit 5 with respect to the main body 9, the positioning shaft 11a is provided on one of the main body 9 and the frame 11 of the transport unit 5, and the other is a guide bush. 9c is provided, and the positioning unit 11 is positioned with respect to the main body 9 by inserting the positioning shaft 11a into the guide bush 9c so that the output shaft of the electric motor 19 is connected to the end of the drive shaft 15 It is possible to put it on.

  Further, on the upper side and the lower side in the conveyance direction of the winding area in the frame 11 of the conveyance unit 5, support rollers 21 having axes in the conveyance orthogonal direction are respectively rotatably supported, and the rotation areas are The passing carrier 17 is supported in a horizontal state.

The infrared heater unit 7 is provided so as to be positionally adjustable in the vertical direction (vertical direction) at a position corresponding to the turning area in the main body 9, and has a length corresponding to the width in the conveyance orthogonal direction. And a plurality of (three in the illustrated example) first and second infrared heaters provided in the heat dissipating cover 23 and having a length corresponding to the width in the conveyance orthogonal direction. 25 (The first infrared heater is the infrared heater located at the middle in the transport direction in the winding area, and the second infrared heater is the infrared heaters located on the upper side and the lower side of the transport direction in the winding area) An infrared transmitting plate 27 such as zero expansion crystallized glass, which is detachably provided to the open end face of the cover 23 and has a high infrared transmittance, is formed.

  As a vertical position adjustment mechanism of the infrared heater unit 7 with respect to the main body 9, an elevator body 9b is supported on the support wall 9a of the main body 9 so as to be movable up and down, and the infrared heater unit 7 is fixed. A stopper screw 9c that can be pressed against the support wall 9a, the stopper screw 9c is screwed in a state in which the elevating body 9b is moved to a desired height position with respect to the support wall 9a, and the infrared heater unit 7 is desired. Fix at the height position. The reference numeral 9d in the figure is a vertically extending elongated hole formed in the support wall 9a, and the stopper screw 9c is inserted so as to be movable in the vertical direction.

The first and second infrared heaters 25 enclose a flat carbon filament and an inert gas in a glass tube having an axial length that coincides with the conveyance orthogonal direction of the conveyance unit 5, and when current is applied, the near infrared rays ~ Output medium wave infrared.

The outer peripheral surface of the glass tube of the first and second infrared heaters 25 is coated with an infrared reflection film 25a around the axis for about half a circumference, and the infrared ray output by the infrared reflection film 25a is transmitted from the transmission part on the opposite side Irradiate intensively. As the infrared reflection film 25a, a metal oxide film such as aluminum oxide or magnesium oxide is employed.

Further, among the first and second infrared heaters 25, the first infrared heater 25 located at the central portion in the transport direction has a flat carbon filament facing the transport surface of the transport unit 5, and the upper side in the transport direction The second infrared heaters 25 respectively positioned on the side and the lower side are positioned in the center at a predetermined distance from the surface of the food 3 placed on the transport surface of the rolled area in the transport unit 5 It is inclined and directed so as to be superimposed on the infrared rays outputted from the first infrared heater 25 respectively .

Although three infrared heaters 25 are arranged in the present embodiment, the present invention is not limited to the number of infrared heaters 25. Further, the first and second infrared heaters 25 of the present embodiment efficiently output infrared rays in the direction orthogonal to the plane by making the carbon filament into a required width and folding the plane.

Moreover, as a filament of the 1st and 2nd infrared heater 25, other than the said planar filament, any of linear and coil shape may be sufficient. In this case, the infrared rays output from the first infrared heater 25 positioned at the center in the transport direction irradiate the transport surface of the transport unit 5 relative to the transport surface, and on the upper side and the lower side in the transport direction, respectively. The pointing by each infrared ray reflective film 25a may be adjusted so that the second infrared heater 25 located is superimposed on the infrared ray from the first infrared heater 25 at the central portion.

As the first and second infrared heaters 25, those that output medium-wave infrared with high thermal energy are suitable, but the first and second infrared heaters 25 that output far infrared rays transmit the food 3 through the far infrared rays. In order to heat the whole, it is not desirable as the 1st and 2nd infrared heater 25 of the present invention.

The heat dissipating cover 23 absorbs the heat of the infrared rays and becomes high in temperature, which may deteriorate the safety. In order to prevent this, a blower member 28 such as a blower is attached to the illustrated front surface of the heat dissipating cover 23 to exhaust the air inside the heat dissipating cover 23 which has been heated to suppress the temperature increase. Reference numeral 23 a in the figure is an opening provided in the heat dissipating cover 23, and releases the air supplied into the heat dissipating cover 23 by the blower member 28.

A tray 29 is detachably provided on the bottom surface of the main body 9 corresponding to one side of the transport unit 5. The tray 29 has a width such that the horizontal direction shown is longer than the width of the winding area, and the front and rear direction shown in the drawing coincides with the transport orthogonal direction of the transport unit 5, and water 29a is stored inside. The tray 29 prevents the drying of the food 3 whose surface is browned by evaporation of the accumulated water and receives the oil and fat dripping from the heated food. Also. The accumulated water 29a prevents the tray 29 from being excessively heated.

  Next, the operation of the roasting apparatus 1 configured as described above will be described. First, the attachment height of the infrared heater unit 7 to the main body 9 according to the height (thickness) of the food 3 to be baked The interval is adjusted so that infrared rays are intensively irradiated on the upper surface of the food 3 placed on the carrier 17.

The degree of the grille formed on the surface of the food 3 indicates the surface state of the food 3, the transport time (transport speed) of the transport unit 5 required to pass through the roasting area, the output of the first and second infrared heaters 25, It is determined by the correlation of the distance between the first and second infrared heaters 25 and the upper surface of the food 3 and the like, and is appropriately set according to the degree of the burnt to be formed. However, if the transport time is extended, the inside of the food 3 may also be heated, so it is desirable to increase the output of the first and second infrared heaters 25 and shorten the transport time (high speed). .

In the present embodiment, the infrared heater unit 7 is moved up and down with respect to the main body 9 to adjust the burn condition by the distance between the first and second infrared heaters 25 and the upper surface of the food 3. Adjustment is made so that only the surface of the food 3 is marked with a desired mark based on the relationship between the transport time (transport speed) of the transport unit 5 required for the above and the outputs of the first and second infrared heaters 25 and the like.

Next, the food 3 to be baked at the upper end of the conveyance direction of the conveyance unit 5 in which the distance between the first and second infrared heaters 25 and the conveyance body 17 is adjusted as described above is conveyed. When the electric motor 13 is driven so that the conveying speed becomes a desired speed after being placed on the upper side, the food on the conveying body 17 is conveyed to the corresponding curling area below the first and second infrared heaters 25.

A current set in advance according to the food 3 is applied to the first and second infrared heaters 25 on the transport body 17 to output an infrared ray having a predetermined output, and the infrared ray irradiated to the surface of the food 3 passing through the inside of the crooked area Burn eyes with the heat energy of

At this time, the infrared rays output from the first and second infrared heaters 25 are reflected downward in the figure by the infrared ray output film illustrated in the figure by the infrared ray reflective film 25a coated on the glass tube, and the food Burned eyes can be efficiently attached by intensively irradiating the surface of 3.

Further, inclined so as to overlap the infrared output from the midsection of the first infrared heater 25 first infrared heater 25 second infrared heater 25 in the transport direction upstream side and the downstream side of the conveyance direction central portion respectively Since the directional arrangement is carried out, the infrared rays from the first and second infrared heaters 25 can be intensively irradiated on the surface of the food 3 to be transported to burn the eyes efficiently. (See Figure 6)

Furthermore, when the surface of the food 3 is burnt by the irradiation of the infrared rays, fats and proteins of the food 3 are burned to generate smoke containing oil. In this example, since the infrared transmitting plate 27 is attached to the open surface of the heat dissipating cover 23 in the infrared heater unit 7, smoke containing oil enters the inside of the heat dissipating cover and is transmitted to the first and second infrared heaters 25. It is possible to prevent the decrease in output due to adhesion, and stable irradiation of infrared rays on the surface of the food 3 for a long time.

Further, outside air is introduced into the heat dissipating cover 23 by the blowing member 28 and the pressure is higher than the outside. For this reason, it can suppress that the smoke containing oil content approachs in the thermal radiation cover.

In addition, when the oil content adhering to the infrared permeable plate 27 increases and the transmittance | permeability of infrared rays worsens, the infrared permeable plate 27 can be removed from the thermal radiation cover 23, and it can wash | clean.

Furthermore, when the surface of the food 3 is baked by the irradiation of the infrared light, the food 3 may be dried by the heat of the infrared light. In this example, the tray 29 in which the water 29a is stored is disposed below the roasting area, and the food 3 can be moisturized by the water 29a heated by the heat of infrared rays to prevent overdrying. Further, the tray 29 is prevented from being excessively heated by the water 29a accumulated in the tray 29.

Furthermore, when baking the surface of the food 3 by irradiation of infrared rays, the heat of the infrared rays may melt and drip the fat of the food 3 to contaminate the main body 3. In the present example, It is possible to prevent the oil, etc. dropped by the tray 29 from being soiled.

When the tray 29 is soiled with the dropped oil or dropped waste, it is possible to maintain the sanitary condition by cleaning after being pulled out from the inside of the main body 9. (See Figure 7)

  When the food 3 having a burnished surface is conveyed to the unloading side of the conveyance unit 5 along with the passage of the rolling area in the conveyance unit 5, the driving of the electric motor 11 is stopped to interrupt the conveyance or continue In the state as it is, the food 3 with its surface being burnt is taken out from the transport unit 5.

Incidentally, an accumulation device such as a roller conveyor (not shown) is disposed on the discharge side of the conveyance unit 5 in an inclined manner, and the food 3 to be transferred out from the discharge means 5 is accumulated on the roller conveyor. You may configure it. In this configuration, the surface of the food 3 can be marked while the conveyance unit 5 is continuously conveyed and driven.

In addition, due to the formation of the grille on the food 3 described above, oil and burnt debris adhere to the carrier 17 and become easily soiled, which is not hygienic. In this example, when the carrier 17 is soiled, the carrier unit 5 is removed from the main body 9 to wash the whole, and the sanitary condition of the carrier 17 with which the food 3 is in direct contact can be maintained safely.

In the above description, the conveyance unit 5 is configured to bridge the net-like conveyance body 17 over the sprockets 13a and 15a respectively provided on the driven shaft 13 and the drive shaft 15 disposed at positions sandwiching at least the turning region. In the transport unit 5, since the loading side and the unloading side are separated, a worker who places and sets the food 3 on the carrier 17 and a worker who takes out the food 3 whose surface is browned is selected. It was necessary to arrange each one, and work efficiency was bad.

As the transport unit 51 of the present invention, as shown in FIG. 8, the transport body 53 configured in a mesh disk shape is configured to rotate at a required speed as the electric motor 55 is driven. The infrared heater unit 7 may be disposed above 53 to constitute the food product rotating apparatus 1.

In the food-rolling apparatus 1 provided with the transport unit 51, for example, an operator is disposed at a position on the opposite side of the infrared heater unit 7 with respect to the center of the transport body 53. The work of transferring and setting the food 3 and the work of taking out the baked food 3 according to the rotation of the carrier 53 can be efficiently performed by one worker.

In the above description, the infrared heater unit 7 can be moved up and down with respect to the main body 9 to variably adjust the distance between the infrared heater 25 and the conveyance surface (the surface of the food 3) of the turning region. The transport body 17 of the area may be lifted upward, and the interval of the transport surface (the surface of the food 3) of the rolled area may be variably adjustable.

That is, a bearing member (not shown) for supporting the support roller 21 disposed on the upper side and the lower side in the conveying direction of the turning area with respect to the frame 11 of the conveying unit 5 is supported elevatingly. The height of the conveyance surface of the conveyance body 17 between the support rollers 21 is made variable by raising and lowering the pivotal support member according to the degree of burnt to be sheathed.

The bearing member is supported by rails provided on the frame 11 so as to be able to move up and down, and a stopper screw (not shown) screwed through an elongated hole (not shown) formed on the frame 11 Fixed to the desired height.

In the above description, the elevating body 9b to which the infrared heater unit 7 is attached is vertically movably supported on the support wall 9a in the vertical direction, and the transport surface of the transport body 17 (the surface of the food 3 placed on the transport body 17) However, the raising and lowering mechanism of the infrared heater unit 7 has an axis in the vertical direction with respect to the support wall 9a, and can rotate a feed screw having an electric motor connected to one end thereof. The feed screw is engaged with a nut (not shown) provided on the lift 9b supported by the support wall 9a and supported by the support wall 9a, and the lift is rotated by the feed screw that rotates with the drive of the electric motor. The space may be made variable by moving up and down.

  In the above description, the conveyance means is unitized and configured to be attachable to and detachable from the main body 9, but in the present invention, the driven shaft and the drive shaft can be rotated on the upper and lower sides of the main body 9 in the conveyance direction. An electric motor may be connected to the drive shaft while supporting the shaft, and the transport body may be stretched around the sprockets provided on the driven shaft and the drive shaft.

  In the above description, the blower member is attached to the heat dissipating cover to introduce air into the heat dissipating cover to prevent overheating. However, the cover is provided with a gap to the inner cover to which the infrared heater is attached and the inner cover. It is good also as a double structure of the outer cover provided and provided with the opening which communicates with waiting, and it is good also as a structure which introduce | transduces air in the gap of an inner cover and an outer cover by a ventilation member, and cools.
