Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a smoker that can significantly shorten smoking time.

[Prior Art] Generally, a smoker has a heat source and a smoking material side saucer disposed in the lower part of the smoker main body, and a ventilation hole that connects to the outside in the upper part of the main body. The inside of the main body is kept at a predetermined temperature using the heat source at the bottom, and the smoking material placed in the saucer is smoked, and the smoke generated from this smoking material is used to smoke the materials placed on the net shelves inside the main body. It is dried and smoked.

In such devices, electric stoves tend to be frequently used as heat sources due to their ease of use.

[Problems to be Solved by the Invention] However, in the case of a device in which a heat source and a smoking material side saucer are arranged in the lower part of the main body, and a ventilation hole that connects to the outside is provided in the upper part of the main body, the main body is essentially a chimney. The difference in weight between the hot gas inside the main body and the air flowing in from the outside creates a pressure difference (ventilation force), which causes a flow of hot gas and air, and the residence time of the generated smoke inside the main body is shortened. It takes a long time for the material to be smoked, and the consumption of smoking material is also large, and furthermore, it is necessary to take measures to protect the heat source and smoking material from the liquid dripping from the material.

Furthermore, since electricity is used as a heat source, the cost for heat capacity is significantly higher than that of fuel, making it uneconomical to use as a heat source for a smoker that requires long-term heating.

In view of the above-mentioned points, the present invention is designed to increase the residence time of generated smoke within the main body, shorten the time until the material is finished smoking, and protect the heat source and smoking materials from dripping liquid. The purpose of the present invention is to provide a smoker that does not require countermeasures, can easily control temperature, and can keep running costs low.

[Means for solving the problem] The smoker according to the present invention has a ventilation opening communicating between the inside and outside of the housing at the lower part of the peripheral side of the housing in which the temperature sensor is built-in, and a door on a part of the peripheral side. A material loading/unloading port that can be opened and closed is provided, and the material can be stored inside the housing. A removable net shelf for placing or hanging is installed, and above the net shelf is a heat source and a tray for smoking material to be smoked by this heat source.
A liquid-receiving dish is placed below each of them.

In addition, the heat source consists of a gas supply device that supplies a gas mixture of gas fuel and air, and a sintered plate of metal fibers having a porosity of 80 to 95%, and rectifies the gas mixture input from the gas supply device. It consists of a burner that ejects water uniformly from the entire surface.

Further, a solenoid valve is provided in the gas supply path of the gas supply device, the opening and closing of which is controlled by a controller connected to a temperature sensor.

[Function] In the present invention, a ventilation hole is formed at the lower part of the circumferential side of the housing, and a heat source and a tray for smoking material to be smoked by this heat source are arranged above the housing. The generated smoke accumulates inside the housing, enveloping the material, and is discharged from the lower ventilation opening over time. As a result, the time it takes for the material to be smoked is shortened.

In addition, a burner made of a sintered metal fiber plate with a porosity of 80 to 95% is used as the heat source, and the mixed gas introduced from the gas supply device is rectified and ejected uniformly from the entire surface. Pressure loss when passing through the burner section is reduced,
The back pressure on the burner is reduced, the surface load can be increased, and the burner itself can be made smaller accordingly. Furthermore, since it is a burner, the temperature rises quickly and the ability to maintain a constant temperature is stable.

In addition, we installed a solenoid valve in the middle of the gas supply path that is controlled to open and close by a controller connected to a temperature sensor.
Temperature control is easy and automation is possible.

[Examples] The present invention will be explained below with reference to illustrated examples. FIG. 1 is a partially broken perspective view of a smoker according to an embodiment of the present invention, and FIG. 2 is a schematic configuration diagram thereof. In Figure 1,
Reference numeral 1 denotes the casing of the smoker, that is, the main body of the smoker.A ventilation opening 2 that communicates the inside and outside of the main body is formed at the lower part of the circumferential side of the main body 1, and a material insertion/extraction opening 4 that can be opened and closed with a door 3 is provided at the center of the front side. Or is provided. A transparent heat-resistant glass 5 is fitted in the center of the door 3 so that the inside of the main body can be visually observed.

In addition, the main body 1 is divided into a large chamber with an internal space located below and a small chamber located above the large chamber, with the large chamber containing the smoking chamber 6,
Further, each of the small chambers forms a storage chamber 7 of a gas supply device 18, which will be described later. The surrounding walls of the smoking chamber 6 including its top wall are surrounded by a heat insulating material 8, so that the heat inside the smoking chamber 6 is not transmitted to the surface of the main body and into the storage chamber 7.

Inside the smoking chamber 6, a temperature sensor 9 for detecting the internal temperature is installed on the back wall, and a mesh shelf 11 for placing the material 10 is attached and detached between the 1st and 2nd rooms (not shown). A burner 12 that is freely straddled and supported above the net Vy111 serves as a heat source and a smoking material 13 that is smoked by the burner 12.
A receiver 15 is placed below the tray 14 of the receiver 14 and the net shelf t].

The burner 12 and the saucer 14 are arranged vertically to face each other, and each is supported by the top wall of the smoking chamber 6. The gas supply device 1 is connected to the gas supply device 18 in the storage chamber 7, and
8, a mixed gas of gas fuel and air is introduced. Moreover, the burner 12 is connected to the lower surface of the shell 16,
That is, the flat burner plate 17 has an opening on the surface facing the receiving tray 14, and in this opening, the gas mixture introduced into the shell 18 from the gas supply device 18 is rectified and ejected uniformly from the entire surface. The mixed gas passing through the burner plate 17, which is installed and ignited by an ignition means (not shown), burns with a flame attached to the surface of the burner plate 17.

The gas supply device 18 includes a gas cylinder 19 that is detachably inserted from the outside of the main body 1, a blower 20 that supplies air, and gas fuel and air from the gas cylinder 19 and the blower 20. A mixer 21 that mixes the mixture at a predetermined ratio and puts it into the shell 16, pipes 22a, 22b, and 22c that connect these, and a pipe 22 that connects the gas supply path, that is, the gas cylinder 19 and the mixer 21.
A pair of flow rate switching solenoid valves 28 connected in parallel in the middle of b.
a, 23b, a blower 20 and each solenoid valve 2.
3a and 23b are automatically controlled by a controller 24 connected to the temperature sensor 9.

Moreover, the control of the blower 2o and each electromagnetic valve 23a, 23b is as follows.
This can also be done manually using the operation buttons on the operation panel 25 installed at the top of the main body 1.

That is, the controller 24 controls the temperature of the burner i2 by controlling the blower 20 and the electromagnetic valves 23a and 23b to input or stop the gas mixture into the shell IB or increase or decrease the input amount. This controls the temperature inside the smoking chamber 6.

The timing of introducing and stopping the mixed gas is automatically performed based on the detection result of the temperature sensor 9 in the smoking chamber 6.
This can also be done manually using the operation buttons on the operation panel 25. In addition, each solenoid valve 23a, 23
Switching for flow rate adjustment by b depends on whether smoking is performed with hot smoking (maintaining the temperature inside the smoking room at 30 to 80 degrees) or hot smoking (maintaining the temperature inside the smoking room at 100 to 140 degrees). , is mainly performed by manual instructions from the operation panel 25.

In the smoker of this embodiment having the above-described configuration, the burner 12 has a burner plate 17 arranged and fixed to cover the lower opening of the shell 1B, which is formed from a sintered metal fiber plate having a porosity of 80 to 95%. did. In addition, the metal fiber that is the material to achieve such a porosity has a fiber diameter of lO~5.
A fiber having a fiber length of 10 μm or more was used. Furthermore,
The excess air ratio of the combustible gas mixture of gas and air (the value obtained by dividing the input air amount by the air amount required for the input gas to chemically react and completely burn) is in the range of 1.0 to 1.2, The flow rate of the combustible gas mixture ejected from the burner plate surface during ventilation is 5 to 30
Each was set within the range of cm/sec. These set values were obtained from the experimental results shown in FIG. 3. Under these operating conditions, the burner plate 17 burns in a red-hot state with flame attached to its surface.

Figure 4 shows the relationship between the distance from the burner plate surface and the temperature at that point when using the burner in the smoker of this example, using the input heat amount as a parameter, and the input heat amount is 20Kcal as a surface load. /cd-h.

40Kcal/d ◆h, 57Kcal/cj
-h is shown as an example. As is clear from the figure, even at a location 200 degrees away from the burner plate surface, a temperature of 300°C or higher was obtained when the surface load was 57 Kcal/cj-h. Although the explanation has been given here using three examples of input heat, the burner 12 used in the smoker according to this embodiment has an input heat of 10 to 80 Kcal/c as a surface load.
It was confirmed that it can be set within the range of -.h.

As described above, in the smoker of this embodiment, the burner 12 is capable of high-load combustion and has high thermal efficiency, so the temperature rises quickly and the ability to maintain a constant temperature is good, and with the same output, compared to the conventional smoker. A heat source that is small, lightweight, and has low running costs is obtained, and the smoking chamber 6 can be set up accordingly, making it possible to use it effectively.

In addition, the burner 12 and the tray 14 for the smoking material i3 are installed in the upper part of the main body, and the ventilation port 2 is formed in the lower part of the main body, so that the generated smoke can stay inside the main body for a long time. This makes it possible to sufficiently smoke the base +410 in a short time, reducing the smoking time by 2 times compared to the conventional method.
You can shorten this to a large width. Furthermore, there is no need to take measures to protect the heat source and smokehouse from the liquid that drips from the water.

Furthermore, in the middle of the gas supply path, there is a solenoid valve 23 whose opening and closing are controlled by a controller 24 connected to the temperature sensor 9.
A and 23b are provided, so automation is possible.

Furthermore, since the flame adheres to the surface of the burner plate 17 and burns, low-load combustion is possible, and temperature control becomes easy.

In the above-mentioned embodiment, the net shelf 11 is installed at a relatively low position in the smoking room 6, and the material 10 is placed on it. When a plurality of levels are provided vertically in the chamber 6 and a net shelf 11 is placed on the upper rail portion, the material 10 may be suspended and supported by the net [11] via a hook.

[Effects of the Invention] As described above, according to the present invention, the residence time of generated smoke within the main body is long, the time until the material is finished smoking can be shortened, and the temperature can be easily controlled. This has the effect of making it possible to keep running costs low.
