Description

Rotary type machine for meat roasting

The present invention places a rotating tray rotatable by a rotation driving unit in the center of the upper surface of the roasting body in the roasting space, and arranges an exhaust control unit near one edge of the upper surface of the roasting body so that the amount of heat discharged can be controlled and assists in the lower side It is a technology that minimizes heat loss and further improves roasting efficiency by additionally installing a hot air supply unit to spread the heat in the roasting space more evenly.

A rotary roaster has been proposed in which meat is placed in a closed roasting space within the body and rotated while heating the meat in the roasting space with a flame.

Most of these existing rotary roasters install a furnace on the bottom of the roasting space and grill the meat above the flame through the flame in the furnace.

In this conventional method, there is a case in which the flame is in direct contact with the upper part of the meat, and in this case, the whole meat is not evenly grilled and the lower part of the meat is burned.

Even if the flame is not in the form of directly closing the meat, it is difficult to achieve uniform roasting of the whole meat because the heat generating point is formed only at the lower point on the same line with the meat and then rises.

Therefore, in the above case, the user has to turn the meat upside down from time to time, which is a hassle, and it also causes a delay in the roasting time.

In addition, in the conventional roasting system, since the exhaust of the heat is simply discharged through the exhaust port, there is a problem that the heat escapes quickly through the central exhaust port and the heat is not evenly distributed, so that the meat is not cooked evenly. There is also a disadvantage in that the heating efficiency is not good because some of the heat is discharged even at the beginning of the heating that needs to be filled.

Therefore, in order to solve this problem, the present inventor places a rotation tray rotatable by a rotation driving unit located in the central portion of the ceiling of the roasting body in the roasting space, and an exhaust control unit that can control the external exhaust amount of hot air in the roasting space near one edge of the upper surface The present invention was completed by discovering that heat loss can be minimized and roasting efficiency can be further improved by not only disposing in the oven, but also installing an auxiliary heat supply unit on the lower side of the roasting space to evenly spread the heat in the roasting space.

The present invention has been proposed to solve the problems of the prior art,

The purpose of this is to improve the heating method so that the meat can be roasted evenly throughout, thereby increasing the roasting efficiency, eliminating the hassle, and shortening the time.

This invention is

As the flame heat generated by the burner is distributed to the first heat supply unit and the second heat supply unit and is simultaneously supplied from the bottom and the side of the roasting space,

It is coupled to the bottom of the hot air supply port 130 and has a structure installed so as to communicate with the roasting space 110 .

The second hot air supply unit 250 serves as a path so that some of the hot air distributed from the distribution unit 230 is moved toward the auxiliary hot air supply port 140 of the roasting body 100 , and the same as the first distribution pipe 242 . In a state in which one end of the second distribution pipe 252 in the form of one end is connected to the other side of the distribution unit 230 and the second connection pipe 254 is connected to the other end of the second distribution pipe, the second connection pipe 254 is the roasting body ( 100) through-coupled to the auxiliary hot air supply port 140 and has a structure installed so as to communicate with the roasting space 110 .

By this structure, the flame heat generated by the burner 210 moves in a state of being distributed to the first heat supply unit 240 and the second heat supply unit 250 through the distribution unit 230 and moves to the main hot air supply port 130, respectively. ) and the auxiliary hot air supply port 140 at the same time has a structure that is supplied to the roasting space (110).

The first heat supply unit 240 and the second heat supply unit 250 may further include a main hot air discharge pipe 260 and an auxiliary hot air discharge pipe 270, respectively.

Among them, the main hot air discharge pipe 260 is not supplied in a straight line form from the bottom of the roasting space upward in the process in which heat is supplied into the roasting space 110 through the first connection tube 244, but is distributed in front, back, left, right, and left directions. It is a factor that leads to supply.

The main hot air discharge pipe 260 has a vertical longitudinal direction, has an open lower part, and has a closed upper part, and has a first heat receiving space in which the heat discharged through the first connecting pipe 244 is primarily accommodated. 262 is formed, and a plurality of first hot air discharge holes 264 for discharging hot air are arranged on the side circumferential surface at intervals.

The main hot air discharge pipe 260 has a lower end coupled to the upper end of the first connecting pipe 244 in a state in which it is located in the roasting space 110 to be described later, so that the inside of the first connecting pipe 244 and the main hot air discharge pipe 260 are formed. The first heat accommodating space 262 is installed to communicate with each other.

The auxiliary hot air discharge pipe 270 is an element inducing heat to be supplied toward the center of the roasting space 110 while the heat is supplied into the roasting space 110 through the second connection tube 254 .

This auxiliary hot air discharge pipe 270 is located in the roasting space 110 but has a left and right longitudinal direction, a second heat receiving space 272 is formed therein, and one end of the second hot air supply port 140 passes through the second hot air supply port 140 . It is coupled to the connection pipe 254 and is installed so that the inside of the second connection pipe 254 and the second heat receiving space 272 are in communication with each other.

A second hot air outlet 274 for discharging hot air is formed at the other end of the auxiliary hot air outlet pipe 270 .

Due to this structure, the flame heat generated by the burner 210 is supplied in a mutually vertical direction at the bottom and side portions of the roasting space 110 , and eventually three-dimensional supply in all directions rather than a simple one direction within the roasting space 110 . Since this is done, heat diffusion can be achieved quickly and uniformly over the entire roasting space.

In this state, the exhaust control unit 300 is further installed in the roasting body 100 .

The exhaust control unit 300 is for controlling the exhaust amount of the hot air as needed in the process of discharging a portion of the heat in the roasting space 110 to the outside during the roasting process, and the exhaust pipe 310 and the control damper 320 are consists of including

Among them, the exhaust pipe 310 serves as a movement path of the heat discharged through the exhaust port 120 of the roasting body 100, and is in the form of a hollow tube with an open upper end and a lower end as a whole, and is located at the upper end of the roasting body 100 The lower end is installed so as to communicate with the exhaust port 120 of the roasting body (100).

Therefore, the exhaust pipe 310 is located near one edge of the upper surface of the roasting body 100 to enable smooth exhaust without interfering with the installation of the rotation driving unit 400 to be described later.

The control damper 320 serves to control whether or not the heat in the roasting space 110 passes through the exhaust pipe 310 and to control the passage amount, and is again to the rotating plate 330 and the operating lever 340 . is composed separately.

Among them, the rotating plate 330 is in the form of a plate having substantially the same area as the inner diameter of the exhaust pipe 310, and serves to control whether or not the hot air passes through the exhaust pipe 310 and the amount of passage, that is, the exhaust amount. It is located in a blocking shape and is installed in a form that can completely block or open the inside of the exhaust pipe 310 by rotating around the hinge as both ends are connected to the exhaust pipe wall through a hinge.

And the operation lever 340 serves to control the rotation of the rotating plate 330 from the outside of the exhaust pipe 310, and is in the form of a general rotation handle, and one end of the exhaust pipe 310 and the rotating plate ( 330) is connected to the hinge connection point and installed.

With this structure, the control damper 320 can completely open and close the inside of the exhaust pipe 310 by rotating the rotation plate 330 inside the exhaust pipe 310 when the user rotates the operation lever 340 at a certain angle, and depending on the rotation angle It has a structure that can arbitrarily control the amount of exhaust heat.

In this state, the rotation driving unit 400 is installed in the roasting body 100 .

The rotation driving unit 400 serves to provide a driving force required for rotation of the rotation tray 500 to be described later, and is again divided into a driving motor 410 and a power transmission unit 420 .

Among them, the driving motor 410 serves as a substantial driving source among the rotation driving units 400 , and is in the form of a general electric motor, in which the motor shaft is rotated by an external power source in a state located above the roasting body 100 .

The power transmission unit 420 serves to transmit the driving force of the driving motor 410 to the rotation tray 500 to be described later, and the reducer 422 is connected to the driving motor 410 and the driving gear 424 is the reducer. It is connected so as to be interlocked with the 422 and the driving gear 424 is connected to a separate rotating shaft 426 penetrating the upper and lower portions of the roasting body 100 and has a structure to rotate around the rotating shaft.

At this time, the rotating shaft 426 vertically penetrates the central point of the upper surface of the roasting body 100 so that the rotation tray 500 to be described later is rotatable in the center of the roasting space 110 .

For reference, the power transmission unit 420 can be implemented in various forms such as a belt and a belt pulley in addition to the structure of the reduction gear 422 and the driving gear.

In this state, the rotating tray 500 is installed in the roasting body 100 .

The rotating tray 500 is to increase the contact rate between the heat in the roasting space 110 and the roasting object by rotating the roasting object while holding it in the roasting space 110, and is in the form of a skeleton in which the frame is interconnected as a whole, and the roasting space ( 110) is installed in a state in which the upper end is connected to the rotating shaft 426.

At this time, the rotation tray 500 is positioned so as to form the top and bottom collinear with the main hot air discharge pipe 260 erected on the floor of the roasting space 110, and as the heat discharged from the main hot air discharge pipe 260 rises, the rotation tray ( 500) to be in sufficient contact with the roasting object seated in it.

By the configuration described above,

In a state in which the roasting object is seated on the rotational tray 500, the rotational tray 500 and the roasting object are rotated, and the heat generated by the burner 210 is the main hot air discharge pipe 260 and the auxiliary hot air discharge pipe ( It is supplied from the bottom surface and the side of the roasting space 110 through 270).

As this process continues, the supplied heat is immediately raised, and the heat is spread and distributed throughout the roasting space 110 .

At this time, since the heat is supplied three-dimensionally from the bottom and the side of the roasting space 110 at the same time in multiple directions, the heat can be spread quickly and reliably in the roasting space 110, and the contact rate with the roasting object is increased to further improve the roasting efficiency. can be

In this roasting process, some of the heat in the roasting space 110 is exhausted to the outside through the exhaust pipe 310. At this time, since the amount of exhaust can be adjusted by arbitrarily adjusting the rotation angle of the rotating plate, the heating efficiency of the roasting space due to excessive exhaust is reduced. etc. can be prevented.

The various features of the present invention described above can be variously modified or combined by those skilled in the art, but these modifications and combinations allow the heat supplied to the roasting space to be simultaneously supplied from the bottom and side walls of the roasting space to improve the heating efficiency of the roasting space. If it is related to the configuration and purpose of increasing and improving the roasting efficiency, it should be determined as belonging to the protection scope of the present invention.
