BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for forming a paste-like paste made of flour or the like into a skin.

[0002]

2. Description of the Related Art An apparatus for producing a skin-like food such as crepe and spring roll skin is known. Such a device includes a rotating drum that rotates at a low speed around a horizontal axis, an electric heater attached to the inner circumferential surface of the rotating drum with an adhesive such as heat-resistant cement to heat the outer circumferential surface of the rotating drum to a predetermined temperature, A hopper containing a paste-like paste made of flour or the like, a flat nozzle for applying the paste-like paste sent from the hopper to the outer peripheral surface of the rotary drum, and a pump for supplying the paste-like paste from the hopper to the flat nozzle And a scooping plate for peeling the skin-like food from the outer peripheral surface of the rotating drum.

[0003] In the skin-like food production apparatus, a paste-like paste is thinly applied to the outer peripheral surface of the rotary drum from a flat nozzle while the rotary drum is previously heated to about 150 to 200 ° C and rotated at a low speed. The paste-like kneaded material is baked by the heat of a rotating drum, and then peeled off from the outer peripheral surface of the rotating drum with a scooping plate to produce a leather-like material.

[0004]

However, in the above-mentioned conventional skin-like food manufacturing apparatus, the degree of heating in the circumferential direction of the rotating drum is likely to be different due to a defect of an adhesive such as heat-resistant cement or an electric heater. Also, there is a disadvantage that the degree of heating of the left and right and the center of the rotating drum tends to be different, so that the degree of burning of the skin-like material varies, and furthermore, the energy unit price of the electric heater is expensive, and the running cost is high. There were disadvantages.

Next, the operation of the skin food manufacturing apparatus 1 will be described. When the motor 18 is operated, the gear 18a rotates while meshing with the teeth 12, and the rotating drum 10 rotates while being supported by the bearing means.

In the fuel supply system, the air supply filter 15
Blower 14 sucks air through the valve opening and closing device 16
The gas is supplied to the mixer 24 through the gas supply pipe 17 while the air is blown to the mixer 24 through the air supply pipe 13 while adjusting the amount of air, thereby mixing the gas and the air. The mixed gas of this gas and air is supplied to the mixed gas supply pipe 2
5 to the inside of the rotating drum 10 and the branch pipe 31
a, 31b, and 31c, and reaches the gas burner 32 for combustion.

When the rotating drum 10 is rotated at a low speed and the inner peripheral surface is heated by a direct fire of the gas burner 32 in the lower region including the center of the hollow portion, the combustion air rises and rises above the hollow portion of the rotating drum 10. Stay in the area. When the pressure in the hollow portion increases, exhaust is naturally performed by the pressure difference between the exhaust pipe 27 on the side surface of the rotary drum 10 and the outside of the rotary drum, and ventilation is performed. Therefore, the rotating drum 10
The atmosphere in the lower portion including the center of the hollow portion has the highest temperature in the hollow portion, so that the air having a relatively low temperature does not drop and stay there, and the rotating drum 10 is efficient. Therefore, it is possible to prevent a difference in the degree of heating between the left and right and the center of the rotating drum 10 and a difference in the degree of heat in the circumferential direction,
The energy efficiency of the skin food manufacturing apparatus can be improved.

When the outer peripheral surface of the rotary drum 10 rises to a predetermined temperature, the paste-like kneaded material is sent to the nozzle 22 by the gear pump 17 and applied to the outer peripheral surface of the rotary drum 10. The applied paste-like kneaded product is baked, and becomes a skin-like food when the rotating drum 10 makes one full rotation.
It is separated from the outer peripheral surface of the rotary drum 10 by the scooping plate.

Next, the energy efficiency of the skin food manufacturing apparatus 1 of the present invention will be described with reference to a comparative example. FIG.
Is a diagram partially showing a cross section of a skin-like food manufacturing apparatus 50 as a comparative example. In this skin-like food manufacturing apparatus 50,
The peripheral plate 51a and the side plate 51b are integrated by welding to form a rotary drum 51, which is fixed to a rotary shaft 55 to be rotatable, while the side plate 51c is rotated via a bearing 58 so as not to rotate. Installed on the shaft 55, thus
A gap 56 is formed between the side plate 51c and the peripheral plate 51a. Further, a gas burner 54 and an exhaust port 52 are provided through the side plate 51c. The gas burner 54 is for heating the rotating drum 51 from the inner peripheral surface with a direct fire, and the exhaust port 52 is connected to a blower (not shown) via an exhaust pipe 53 to connect the rotating drum 51 to the rotary drum 51. It is to perform forced ventilation inside. Further, a burner ignition spark rod and a misfire detection frame rod are arranged near the gas burner 54. The limit of the heat resistance of the electric wire used for the burner ignition spark rod and the misfire detection flame rod is about 350 ° C. The peripheral plate 51
a and the thickness of the steel plate of the side plates 51b and 51c,
The dimensions and the like of 1 were the same as those of the skin food manufacturing apparatus 1 of the present invention.

As a result of producing spring roll skin using both the skin food manufacturing apparatus 10 of the present invention and the skin food manufacturing apparatus 50, the amount of gas used in the apparatus of the present invention was 6 times that of the comparative example.
It turned out to be about a percentage.

This is because the apparatus of the present invention uses the rotating drum 10
Is heated at about the same temperature of about 300 ° C. in the entire hollow portion, whereas in the apparatus of the comparative example, the rotating drum 51 is heated.
When the outer peripheral surface is heated to a predetermined temperature, the temperature of the hollow portion near the gas burner 54 rises to about 400 ° C.,
This is because the temperature in the lower region of the hollow portion remains at about 100 ° C., and the temperature distribution in the rotating drum 51 becomes uneven.

In the apparatus of the comparative example, from the viewpoint of heat resistance, the temperature in the region above the hollow portion near the gas burner 54 must be reduced to at least about 350 ° C., so that the combustion air is forcibly discharged from the exhaust port 52. Then, there is a disadvantage that the combustion efficiency is remarkably reduced. However, in the device of the present invention, the entire area of the hollow portion of the rotary drum 10 is uniformly controlled only by natural ventilation from the exhaust pipe 27 by controlling the gas flow rate and the air mixing amount. Temperature, for example, about 350 ° C., so that the energy efficiency is significantly improved.

[0023]

According to the apparatus for producing skin-like food of the present invention, the gas burner is arranged below the center of the hollow portion of the rotating body, including the center, so that the radiant heat of the gas burner is reduced below the center of the hollow portion. Is heated, and the combustion air rises and stays above the hollow portion of the rotating body.On the other hand, the amount of air is preferably adjusted by natural ventilation from a substantially central opening on the side of the rotating body so that the high-temperature combustion air is not excessively exhausted. Therefore, the rotating body is efficiently heated in the entire hollow portion, and the energy efficiency of the skin food manufacturing apparatus can be improved.

In the present invention, since the gas burner is disposed in the hollow portion of the rotating body without being fixed to the rotating body, a physical external force due to thermal contraction of a steel plate or the like constituting the rotating body does not act on the gas burner. Since the displacement and failure of the gas burner due to the external force can be prevented, it is possible to prevent a difference in the degree of heating between the left and right and the center of the rotary drum.
