Description

The present invention relates to a cold smoker capable of producing high-quality cold smoked products (cold smoked products are smoked products made at 30 ° C. or lower) by easily generating low-temperature smoke.

In recent years, smoked dishes using smokers have become more and more popular as one of the cooking methods in the outdoors, as one of the cooking methods in restaurants, or as one of the cooking methods in each household. Smoked products generate smoke by burning smoked materials such as smoked chips and smoked wood with flames such as burners, and apply this smoke to foodstuffs such as fish, wieners, and ham, which are peculiar to smoked foods. It is a cooking method in which the bactericidal and antiseptic ingredients contained in smoke are infiltrated while flavoring.

Here, the types of smoking methods will be described.

There are mainly three types of smoking methods: hot smoking method, hot smoking method and cold smoking method. The hot smoking method is, for example, a method of smoking in a high temperature environment of 80 ° C. or higher, in which foodstuffs are heat-treated while being smoked, and salting, tide removal, drying, and smoking are all performed in a short time. Although the hot smoking method is a simple smoking method, it is not suitable for preserving food, which is the original purpose of smoking, but rather it can be said to be a simple smoking method for enjoying the flavor of smoked food.

The hot smoking method is the most common smoking method. For example, it is a method of smoking in a temperature environment of 30 to 80 degrees, and a long smoking time is required.

The cold smoking method is, for example, a method of exposing food to smoke in a temperature environment of 30 degrees or less, and is a method of smoking at a low temperature so as not to heat the food.

As conventional smoking devices, various smoking devices and smoking methods classified into the hot smoking method have been proposed. In particular, the smoking devices and smoking methods classified into the cold smoking method are described in Patent Document 1 shown below. Smoked equipment has only been proposed, and many prior arts have not been found.

Here, in Patent Document 1, a chimney is installed outside, and the length of the cooling pipe can be freely changed without changing the positions of the firing port and the cold smoking device that can keep the smoke temperature at or below the outside temperature. A cold smoking device that can be used has been proposed.

Japanese Unexamined Patent Publication No. 2005-13183

However, since the conventional cold smoking device is provided with a structure for securing the length of the cooling pipe, it is inevitable that the device as a whole becomes complicated and large. For this reason, there is a problem that it is not easy to carry it for outdoor use or it is installed indoors for indoor use, and it is necessary to secure an installation space.

In addition, the cold smoking device is also required to have appropriate durability.

Therefore, in consideration of the above circumstances, an object of the present invention is to provide a cold smoker having good durability and capable of miniaturization with a simple structure.

The invention according to claim 1 connects a first housing portion capable of accommodating a smoke material, a second housing portion capable of accommodating a food material, and the first housing portion and the second housing portion.

The air flow supply section includes an air flow path throttle section for narrowing the flow path of the air flow generated in the flow generation section, and the air flow supply section includes a plate having an opening penetrating in the thickness direction at the center portion, and the air By interposing the flow path throttle portion inside the opening of the plate, the area of the air flow path partitioned by the outer edge portion of the air flow path throttle portion and the inner edge of the opening of the plate is narrowed. It is characterized in that a throttle flow path is formed.

The invention according to claim 2 connects a first housing portion capable of accommodating a smoke material, a second housing portion capable of accommodating a food material, and the first housing portion and the second housing portion. A cold smoker having a smoke guide portion capable of inducing smoke from the first housing portion to the second housing portion, and the first housing portion supports the smoke material. An air flow supply unit that has a smoke material support unit and an air flow generation unit that generates an air flow and supplies the air flow to the smoke material, and the smoke material support unit and the air flow supply unit. A partition portion that is interposed between the portions to allow the air flow to pass through and prevent the smoke generated from the smoke material from entering the air flow supply portion, and a partition portion provided in the partition portion to prevent the smoke from entering the air flow supply portion. A first plate having an air flow path throttle portion for narrowing the flow path of the air flow generated in the flow generation portion, and the air flow supply portion having an opening penetrating in the thickness direction at each central portion. And a second plate, the first plate is located closer to the airflow generator than the second plate, and the second plate is located closer to the partition than the first plate. Then, the air flow path throttle portion is interposed inside the opening of the first plate so as to be partitioned between the outer edge portion of the air flow path throttle portion and the inner edge of the opening of the first plate. The area of the air flow path is narrowed to form the first throttle flow path, and the air flow path throttle portion is interposed inside the opening of the second plate to form the air flow path throttle portion. The area of the air flow path partitioned by the outer edge portion and the inner edge of the opening of the second plate is narrowed to form the second throttle flow path, and the opening area of the second throttle flow path is the said. It is characterized in that it is smaller than the opening area of the first throttle flow path.

According to the present invention, the smoke material supported by the smoke material support portion of the first housing portion is ignited or heated, air is supplied from the air flow supply portion, and smoke is generated from the smoke material. The smoke generated from the smoke material of the first housing portion flows to the second housing portion through the smoke guiding portion, and is smoked by applying it to the food material to perform the smoking treatment.

Here, since a partition portion is provided between the smoke material support portion and the air flow supply portion, the air flow can be provided to the smoke material and the smoke generated from the smoke material flows back. It is possible to prevent the air from entering the air flow supply unit side. As a result, it is possible to prevent smoke from adhering to the air flow supply unit, and it is possible to suppress the generation of dirt on the air flow supply unit and the reduction in product life.

Since the air flow supply unit has an air flow generation unit that generates an air flow and an air flow path throttle unit that narrows the flow path of the air flow generated in the air flow generation unit, the air flow passes through. The flow path is throttled by the air flow path throttle section. Therefore, the flow velocity of the air flow when passing through the air flow path throttle portion becomes high, and the smoke material is applied to the smoke material while maintaining the high speed. As a result, the oxygen supply capacity for the smoke material is improved, and the smoke generation efficiency is increased.

The area of the air flow path partitioned by the outer edge portion of the air flow path throttle portion and the inner edge of the opening of the first plate is narrowed to form the first throttle flow path, and the outer edge of the air flow path throttle portion is formed. The area of the air flow path partitioned by the portion and the inner edge of the opening of the second plate is narrowed to form the second throttle flow path, and the opening area of the second throttle flow path is the first throttle flow. Since it is smaller than the opening area of the path, the flow velocity becomes faster when the air flow passes through the first throttle flow path, and the air flow whose flow velocity becomes faster due to passing through the first throttle flow path is the first. When passing through the throttle flow path of No. 2, the flow velocity becomes even faster.

It is sectional drawing of the cold smoking machine of this invention. It is sectional drawing of the 1st housing part which comprises the cold smoking machine of this invention.

The cold smoker according to the present embodiment of the present invention will be described with reference to the drawings.

As shown in FIGS. 1 and 2, the cold smoker 10 mainly has a first housing portion 12 capable of accommodating the smoke material M, a second housing portion 14 capable of accommodating the food material F, and a first. The housing portion 12 and the second housing portion 14 are connected to each other, and a smoke guiding portion 16 capable of inducing smoke S from the first housing portion 12 to the second housing portion 14 is included.

The first housing portion 12, the second housing portion 14, and the smoke guide portion 16 are detachably configured from each other, and are combined to form the cold smoker 10. As a result, the cold smoker 10 can be easily assembled and can be miniaturized.

[First housing part]
The first housing portion 12 is a so-called hollow casing, and is made of an aluminum square pipe.

Inside the first housing portion 12, there are a smoke material support portion 18 that supports the smoke material M, an air flow supply portion 20 that supplies an air flow B to the smoke material M, and a smoke material support portion. It has a partition portion 22 that is interposed between the 18 and the air flow supply unit 20 to pass the air flow B and prevent the smoke S generated from the smoke material M from entering the air flow supply unit 20. doing.

In the air flow supply unit 20, for example, the first plate 20a, the second plate 20b, the third plate 20c, the fourth plate 20d, the fifth plate 20e, and the partition plate 22a are the first housing portions. A plurality of fixing bolts 24 penetrate and are integrally assembled in a state of being arranged at predetermined intervals along the longitudinal direction of the twelve.

The first plate 20a is a square or rectangular plate material. The first plate portion 20a is provided with an air volume adjusting controller 28 for controlling the driving force of the air flow generating portion 26 and controlling the flow rate of the air flow B generated from the air flow generating portion 26.

As the air flow generating unit 26, for example, a blower fan is used.

The second plate 20b is a square or rectangular plate material, and an opening H1 (not shown in FIG. 1) penetrating in the thickness direction is formed in the central portion thereof. An air flow generating portion 26 is attached to the second plate 20b so as to close the opening H1. The outer edge portion of the second plate 20b is in contact with the inner wall surface of the first housing portion 12. Therefore, the air flow B on the downstream side of the second plate 20b and the smoke S generated from the smoke material M are prevented from entering the first plate 20a side from the outer edge portion of the second plate 20b.

The third plate 20c, the fourth plate 20d, and the fifth plate 20e are so-called sealing plates, which are square or rectangular plate materials, but the openings H2, H3, and H4 penetrating the central portion in the thickness direction (FIG. (Not shown in 1) are formed respectively. The outer edges of the plates 20c, 20d, and 20e are in contact with the inner wall surface of the first housing portion 12. Therefore, the air flow B that has passed through the opening H2 of the third plate 20c and the smoke S generated from the smoke material M enter (backflow) from the outer edge of the third plate 20c to the second plate 20b side. Is being prevented.

Openings H2, H3, and H4 (not shown in FIG. 1) are formed in the central portions of the third plate 20c, the fourth plate 20d, and the fifth plate 20e, but air is formed in the openings H2, H3, and H4. Since the air flow B from the flow generating portion 26 flows toward the smoke material M side, the smoke S does not flow back through the openings H2, H3, and H4.

The partition plate 22a is a plate material that constitutes the partition portion 22, and prevents the smoke S generated from the smoke material M from entering the air flow generating portion 26 side. The partition plate 22a is formed in a square or rectangular shape. However, the outer edge portion of the partition plate 22a does not abut on the inner wall surface of the first housing portion 12. Therefore, a gap is formed between the outer edge portion of the partition plate 22a and the inner wall surface of the first housing portion 12. This gap serves as a flow path for the air flow B from the air flow generating portion 26, and enables the air flow B to reach the smoke material M.

An air flow path throttle portion 32 is attached to the partition plate 22a. The air flow path throttle portion 32 is formed in a conical or pyramidal shape, and is located on the opposite side of the smoke material support portion 18 with the partition plate 22a interposed therebetween. As a result, the area of the air flow path 44 (not shown in FIG. 1) partitioned by the outer edge portion of the air flow path throttle portion 32 and the inner edge of the opening H3 of the fourth plate 20d is reduced, and the area of the first throttle flow path is reduced. 46 (not shown in FIG. 1) is formed, and the area of the air flow path 44 partitioned by the outer edge portion of the air flow path throttle portion 32 and the inner edge of the opening H4 of the fifth plate 20e is reduced. Two throttle flow paths 48 (not shown in FIG. 1) are formed. Further, the opening area of the second throttle flow path 48 is smaller than the opening area of the first throttle flow path 46 (opening area of the first throttle flow path 46> opening area of the second throttle flow path 48). In this way, the air flow path 44 is gradually narrowed down along the flow direction of the air flow B generated from the air flow generating unit 26.

The air flow path throttle portion 32 is also referred to as a wind guide portion.

Generally, when the opening area of the air flow path 44 is narrowed, the flow velocity of the fluid becomes faster (larger) when the fluid such as an air flow passes through the narrowed portion according to Bernoulli's theorem. In the present embodiment, this principle is used, and the flow velocity becomes faster when the air flow B passes through the first throttle flow path 46, and the flow velocity becomes faster when the air flow B passes through the first throttle flow path 46. When the air flow B passes through the second throttle flow path 48, the flow velocity becomes even faster. Therefore, when the air flow B escapes from the outer edge of the partition plate 22e and collides with the smoke material M, the flow velocity of the air flow B becomes significantly faster.

A smoke material support portion 18 that supports the smoke material M is detachably attached to the partition plate 22a. The smoke material support portion 18 is, for example, a support plate for supporting the smoke material M. One end of the smoke material support portion 18 is engaged with and fixed to the end portion of the fixing bolt 24.

The smoke material support portion 18 is not limited to a physically existing member called a support plate. For example, even if there is no physically present member, the area or space of the first housing portion 12 where the smoke material M is located can be recognized as the smoke material support portion 18 or the smoke material accommodating portion. It is included in the concept of the smoke material support portion 18, whether it is tangible or intangible. Since the inventor of the present application also assumes such an intangible structure, the significance of the smoke material support portion 18 should be widely interpreted regardless of whether it is a tangible or intangible object.

As the smoke material M, for example, smoked wood can be used, and smoke chips obtained by processing well-known wood into shards can be used.

A plurality of through holes 42 penetrating the inside and outside of the first housing portion 12 are formed between the second plate 20b and the third plate 20c of the first housing portion 12. Therefore, the surface area of the first housing portion 12 in contact with the outside air increases at the portion where the through hole 42 is formed.

A handle 30 is attached to the first housing portion 12. The handle 30 is preferably made of a wooden round bar.

A first connection portion 34 is formed in the first housing portion 12. One end of the smoke guide 16 is connected to the first connection 34.

Although not shown, the first housing unit 12 is provided with a power supply unit that supplies electric power for driving the air flow generating unit 26. The power supply unit can be connected to a mobile phone or a terminal via USB, for example, and can also be used by plugging it into a home outlet. Further, the rechargeable battery may be housed in the first housing portion 12 to drive the air flow generating portion 26.

[Second housing]
The second housing portion 14 is made of, for example, a hollow aluminum square pipe, and is provided with a food material plate 36 on which the food material F is placed. However, the food material plate 36 is not essential, and the food material F may be placed directly on the bottom surface of the second housing portion 14.

A second connection portion 38 is formed in the second housing portion 14. The other end of the smoke guide 16 is connected to the second connection 38.

The second housing portion 14 is provided with a smoke discharging portion 40. The smoke S inside the second housing portion 14 is discharged to the outside via the smoke discharging portion 40. The smoke discharging portion 40 is formed in the shape of a hollow pipe.

[Smoke guide]
The smoke guide portion 16 is configured so that a plurality of components can be connected to each other, and the length (total length) can be adjusted. The number of components of the smoke guide 16 is appropriately increased or decreased depending on the content or situation of the smoking process. The smoke guide portion 16 is formed in the shape of a hollow pipe so that smoke can pass through.

Next, the operation of the cold smoker 10 according to the present embodiment of the present invention will be described.

As shown in FIGS. 1 and 2, a smoke guide portion 16 connects between the first housing portion 12 and the second housing portion 14. When the smoke material M housed in the first housing portion 12 is ignited or heated and the air flow generating portion 26 is driven, an air flow B is generated inside the first housing portion 12.

After passing through the opening H2 of the third plate 20c, the air flow B enters the first throttle flow path 46 formed by the inner edge of the opening H3 of the fourth plate 20d and the outer edge of the air flow path throttle 32. And pass through. At this time, since the opening area of the first throttle flow path 46 is narrowed down smaller than the opening area of the opening H2 of the third plate 20c, the flow velocity increases when the air flow B passes through the first throttle flow path 46. It will be faster (first acceleration).

Subsequently, the air flow having a high flow velocity enters and passes through the first throttle flow path 46 formed by the inner edge of the opening H3 of the fourth plate 20d and the outer edge of the air flow path throttle portion 32. At this time, since the opening area of the second throttle flow path 48 is narrowed smaller than the opening area of the first throttle flow path 46, the flow velocity becomes even faster when the air flow B passes through the second throttle flow path 48. (Second acceleration).

The air flow B whose flow velocity has increased in two steps passes through the gap between the outer edge portion of the partition plate 22a and the inner wall surface of the first housing portion 12, and is vigorously blown into the smoke material M. As a result, smoke is continuously emitted from the smoke material M, and a smoke flow is continuously generated. By applying an air flow having a predetermined flow velocity to the smoke material M in this way, the efficiency of generating the smoke S is increased.

The smoke S is blocked by the partition plate 22a and does not enter the air flow generating portion 26 side, but flows along the air flow B to the smoke guiding portion 16 side. As a result, the smoke S does not adhere to the air flow generating portion 26, and the air flow generating portion 26 can be prevented from being contaminated or the durability can be prevented from being lowered.

The smoke S enters and flows into the hollow smoke guide portion 16 as a smoke stream. The temperature of the smoke S gradually decreases in the process of passing through the smoke guide portion 16. That is, the temperature of the smoke S flowing through the inlet side of the smoke guide portion 16 located on the first housing portion 12 side is the highest, and the smoke passes through the outlet side of the smoke guide portion 16 located on the second housing portion 14 side. The temperature of smoke S becomes the lowest.

The smoke S that has passed through the outlet side of the smoke guide portion 16 enters the second housing portion 14. Inside the second housing portion 14, the food material F is smoked by the smoke S, and the smoking process by the cold smoking method is executed. After that, the smoke S is discharged to the outside through the hollow smoke discharging unit 40.

Here, the first housing portion 12 has the heat amount of the smoke S and the heat amount of the heat generated by the heating of the smoke material M, but the first housing portion 12 is formed with a plurality of through holes 42. Therefore, the surface area of the first housing portion 12 in contact with the outside air increases at least in the portion where the through hole 42 is formed. As a result, the heat dissipation effect of the first housing portion 12 is enhanced, and it is possible to promote heat dissipation of the heat transferred from the smoke S to the first housing portion 12. As a result, the temperature rise of the first housing portion 12 can be suppressed, and the safety when handling the first housing portion 12 can be ensured.

Further, since the partition plate 22a is fixed to the air flow supply unit 20, the partition plate 22a and the air flow supply unit 20 are integrally connected. As a result, the partition plate 22a can be easily positioned with respect to the air flow supply unit 20, and the backflow prevention effect of the smoke S is stabilized with high accuracy.

Further, since the smoke material support portion 18 is fixed to the air flow supply portion 20, the smoke material support portion 18 can be taken out at the same time when the air flow supply portion 20 is taken out from the first housing portion 12. As a result, the smoke material support portion 18 can be easily attached to and detached from the first housing portion 12.

Further, since the air flow path throttle portion 32 is fixed to the partition plate 22a, when the air flow supply portion 20 is attached to the first housing portion 12, the air flow path by the air flow path throttle portion 32 has already been formed. The diaphragm is formed. As a result, the throttle formation of the air flow path becomes easy and reliable.

Further, since the air flow generating unit 26 is composed of a blower fan whose air volume can be adjusted, the flow rate of the air flow B can be easily adjusted.

The contents described in the above-described embodiment are merely examples for explaining the present invention, and various modifications can be made without departing from the gist of the present invention.
