1 is a front view illustrating a high-pressure steam-heating roasting apparatus according to the present invention, and FIG. 2 is a side cross-sectional view illustrating a high-pressure steam-heating roasting apparatus according to the present invention.

As illustrated, the present invention largely consists of an apparatus main body 10, a roasting tube 20, a hole bore 30, a heater 40, a steam forming unit 50, a pressure holding valve 60, and a steam discharge valve 70 and a residual pressure release valve 80.

The device body 10 of the present invention is configured to form an empty installation space 11, and a roasting container 20 is fixedly installed at a certain height inside the device body 10, and a high-pressure pump is provided at the bottom. It is a shape to be

In addition, pipes (not shown) through which high-pressure water is supplied from the high-pressure pump to each roaster 20 are installed, and pipes (not shown) through which steam and pressure are discharged from each roaster 20 are connected.

In the device main body 10, the grilling container 20 has a tubular configuration in which one end is open while the open end is formed to be opened and closed by the door 21.

The roasting container 20 has one open end fixed to the front of the device body 10 so that a part thereof protrudes forward. Let it be.

The door 21 may be formed of a transparent material so that the inside of the roasting container 20 can be seen, but is not limited thereto, and the door 21 is locked or locked by manual operation of the locking lever 22. let it be released

It is also preferable to connect a pressure gauge 23 to the door 21 so that the pressure inside the roasting container 20 can be checked with the naked eye from the front of the main body 10 .

In addition, a temperature sensor (not shown) is installed in the roasting tube 20 together with the pressure gauge 23 so that the internal temperature can always be checked during cooking.

As illustrated, the roasting barrel 20 is preferably formed in a cylindrical shape, and a perforated cylinder 30 having an outer diameter smaller than the inner diameter of the roasting barrel 20 is provided inside the roasting barrel 20.

As shown in FIG. 3, the perforated cylinder 30 is an outer circumferential surface formed to be spaced apart from the inner circumferential surface of the roasting cylinder 20 at a predetermined interval, and a plurality of holes 31 are perforated, and the inner circumferential surface is formed to be a flat plate formed so that roasting materials can be placed. A shelf shoulder 33 is formed on which both ends of the shelf 32 can be placed.

That is, the ledge 33 is formed so that a certain width protrudes on the same horizontal line in a direction facing each other while having one end fixedly connected to the inner circumferential surface of the other hole 30.

It is more preferable to form one or more such ledges 33 at different heights in the hole 30.

In particular, a bar-shaped heater 40 is installed between the roasting tube 20 and the other bore 30.

The heater 40 may be formed in a rod shape so that it is formed as a plurality of pieces between the inner circumferential surface of the roasting tube 20 and the outer circumferential surface of the other hole 30, but one by connecting the ends of these rod-shaped heaters 40 It can also be formed with the configuration of.

The configuration of the apparatus main body 10, roasting tube 20, other common tube 30, and heater 40 is almost the same as the previous one.

A steam forming unit 50 is connected to the grilling tube 20, and the steam forming unit 50 sprays high-pressure water into the roasting tube 20, the inside of which is heated by the heater 40, in the form of mist.

That is, the steam forming unit 50 has a high-pressure pump 51 installed at the bottom of the inside of the device body 10 so that drinking water forcedly introduced from the outside is formed at high pressure to form a roasting container 20, each A spray nozzle 52 is installed in the roaster 20 so that the drinking water pumped from the high-pressure pump 51 is atomized in a mist form and supplied to the inside of the roaster 20 .

In this way, the steam forming unit 50 atomizes high-pressure water so that it is sprayed into the roasting container 20, and steam at a certain temperature is formed by contact with hot air heated by the heater 40 inside the roasting container 20. .

Since the high-pressure pump 51 used at this time requires 200 to 300 W for driving, power consumption can be minimized, and if the high-pressure water supplied in this way is sprayed through the spray nozzle 52, the roaster 20 will have a mist shape. When a certain temperature is applied to the spray supplied in this way, it is possible to provide the same steam as the steam generated by the steam boiler.

The roaster 20 that forms steam maintains a previously set temperature and pressure during cooking, and for this, a pressure maintaining valve 60 is installed in the roaster 20 .

The pressure maintaining valve 60 is automatically opened when the internal pressure of the roasting container 20 exceeds a certain level, and steam inside the roasting container 20 is discharged so that the internal pressure is continuously maintained below a certain level.

To this end, the pressure holding valve 60 raises the internal temperature of the roaster 20 to 250° C. or higher during cooking, so that the valve head 61 is heated to a high temperature so that the seal can be stably maintained even under this temperature condition. It is more preferable to form a conical or curved surface in contact with the valve seat 62 so that it can be in close contact with the valve seat 62 while being formed of metal or synthetic resin that is resistant to heat.

In this way, when the internal pressure of the roaster 20 reaches a certain level or higher during cooking, the pressure holding valve 60 is automatically opened to prevent further pressure rise, and the control set pressure by the pressure holding valve 60 is 2 bar However, the control pressure may be set differently according to the cooking material.

To this end, the valve head 61 is elastically supported by a compression spring 63, and the compression spring 63 allows the spring force to be adjusted by a bolt or nut-shaped pressure adjusting sphere 64 so that the operating pressure can be adjusted. .

A steam discharge pipe 65 is formed in the pressure maintaining valve 60 so that steam inside the roasting container 20 can be discharged.

On the other hand, during cooking, the pressure in the roasting container 20 is kept constant by the pressure maintaining valve 60 so that cooking is performed. When cooking is finished, the steam in the roasting container 20 is discharged to the outside through the steam discharge valve 70. It is discharged.

That is, the steam discharge valve 70 is kept closed during cooking, and is automatically opened when cooking is finished to naturally discharge high-pressure steam to the outside while lowering the internal pressure below a certain level.

To this end, it is more preferable that the steam discharge valve 70 is formed as a solenoid valve to automatically open and close depending on whether or not cooking is performed in the roasting container 20 .

In this way, even if the high-temperature and high-pressure steam filled inside the roasting container 20 is discharged through the steam discharge valve 70, residual pressure steam still remains inside the roasting container 20.

To this end, a residual pressure discharge valve 80 opened and closed by a manually operated opening/closing lever 81 is provided on the side of the main body 10 as shown in FIG. 5 .

That is, the residual pressure discharge valve 80 is opened and closed by manual operation of the open/close lever 81 so that even the residual pressure remaining in the roasting container 20 can be discharged. At this time, the open/close lever 81 of the residual pressure discharge valve 80 If is not operated to open, the door 21 of the roasting container 20 does not unlock the locked state.

In other words, as shown in FIG. 6, the locking lever 22 for locking or unlocking the door 21 of the roaster 20 is formed to partially protrude outside the device body 10, and the residual pressure discharge valve 80 The opening/closing lever 81 of the locking lever 22 of the door 21 is opened only in the state in which the residual pressure discharge valve 80 is opened by rotating the opening/closing lever 81 upward by forming the upper portion of the locking lever 22 to cross. is operated upward so that the door 21 can be opened only in a state in which steam is completely removed from the roasting container 20.

As in the above configuration, the action and effect of the high-pressure steam heating type roasting device according to the present invention will be described in detail as follows.

The present invention provides a plurality of roasting barrels 20 in the device body 10 and allows each roasting barrel 20 to be independently controlled, so that each roasting barrel 20 can be operated selectively or simultaneously.

Therefore, according to the present invention, various roasting ingredients can be inserted into these roasting containers 20 so that multi-cooking can be performed at the same time, and a large amount of cooking can be done at the same time by inserting the same roasting ingredients.

In the roasting container 20, as in the past, while the roasting materials are placed on the shelf 32, they are inserted along the ledge 33 formed on the inner circumferential surface of the other common container 30 so that they are placed.

In the state in which the roasting materials are inserted, the inside of the other hole 30 is heated to a certain temperature by the heater 40 in each roasting container 20 of the apparatus main body 10, and as shown in FIG. 7, the steam in the roasting container 20 The high-pressure water supplied by the high-pressure pump 51 of the forming unit 50 is sprayed into the inside through the spray nozzle 52 in the form of a mist to form steam as it comes into contact with internal heat, and this steam heat moves through the shelf 32 It cooks while being in contact with the grilled ingredients placed on it.

During cooking, in the roaster 20, the internal pressure is gradually increased by the heated steam atomized through the spray nozzle 52 of the steam forming unit 50, and when the internal pressure of the roaster 20 rises above a certain level Since the valve head 61 of the pressure maintaining valve 60 moves while compressing the compression spring 63, the inside of the roasting container 20 is in communication with the steam discharge pipe 65, and the steam passes through the steam discharge pipe 65. will emit

As the steam in the roasting container 20 is discharged through the steam discharge pipe 65, the pressure inside the roasting container 20 decreases again, so the pressure inside the roasting container 20 no longer rises above the pressure set by the pressure maintaining valve 60. This ensures that stable and uniform cooking is possible.

When cooking is done for the set time and ends, the steam discharge valve 70 is immediately opened to discharge the steam inside the roasting container 20. Since the steam discharged in this way is discharged by the internal pressure, steam is discharged under a certain pressure. Emissions do not work smoothly.

Steam is automatically discharged by the operation of the steam discharge valve 70, so that residual pressure still remains inside the roasting container 20 even when the internal pressure of the roasting container 20 becomes almost zero.

Even if the steam discharge by the steam discharge valve 70 is completed, in the present invention, the locking lever 22 of the door 21 cannot be operated by the open/close lever 81 of the residual pressure discharge valve 80, so the open/close lever must first be performed. The door 21 is opened by operating the locking lever 22 only after the residual pressure inside the roasting container 20 is completely removed by operating the opening/closing lever 81 by operating the 81 upwardly. make it possible

Therefore, it is possible to prevent accidents such as burns that may occur when the heated internal heat is discharged forward by opening the door 21 .

In other words, when the residual pressure discharge valve 80 is opened by operating the opening/closing lever 81, even though a large amount of steam is discharged by the steam discharge valve 70, the high-temperature steam still remaining inside the roasting container 20 Even if the door 21 is opened, damage such as burns is no longer caused because it is completely discharged.

In this way, the present invention can form steam more quickly through the steam forming unit 50 using the high-pressure pump 51 and the spray nozzle 52, thereby significantly reducing the cooking time and minimizing power consumption during cooking to maintain the device. to reduce management costs.

In addition, the present invention stabilizes the pressure maintenance during cooking in each grilling container 20 through the pressure maintaining valve 60, the steam discharge valve 70, and the residual pressure discharge valve 80, while steam is gradually discharged after cooking is finished. It has a very useful effect that enables safer use and handling.

As such, the present invention is not limited to the described embodiments, and it is obvious to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the present invention. Therefore, it should be said that such modifications or variations fall within the scope of the claims of the present invention.
