The mounting portion 331 is tilted up and down at a second time interval based on the rotating pillar portion 31, so that the object to be accommodated in the accommodation space is stirred by the extension portion 333.

Specifically, the mounting portion 331 may be tilted up and down based on the rotating pillar portion 31 while the rotating pillar portion 31 is rotated relative to the base portion 10.

The extension portion 333 may be formed to rotate relative to the mounting portion 331.

Accordingly, the extension portion 333 is interlocked with the rotational movement of the rotating pillar portion 31 and is moved along the circumferential direction of the accommodation space based on the rotating pillar portion 31, along the circumferential direction While moving, the vertical movement of the tilting motion by the mounting part 331 is rotated relative to the mounting part 331, so that the immature objects in contact can be randomly mixed.

The extension portion 333 may include a rotating shaft portion that is rotatably connected to the mounting portion 331 and a radiating portion radially mounted to the rotating shaft portion.

The spinning unit, by lifting and dropping a portion of the object to be housed, it is possible to more effectively implement random stirring of the object to be housed.

The heat providing part 40 is connected to the air providing part 20, and the first heat providing piece 41 and the stirring part 30 to increase the temperature of the air supplied by the air providing part 20. While connected, a second heat supply piece 42 for supplying heat to the stirring unit 30 may be provided.

In the control unit 60, when the temperature value measured by the temperature measuring unit 50 is lower than a preset temperature, the first heat providing piece 41 and the second heat providing piece 42 are operated. It can be done.

In addition, when the temperature value measured by the temperature measuring unit 50 is higher than a preset temperature, the control unit 60 may include the first heat providing piece 41 and the second heat providing piece 42. The heat providing unit 40 may be controlled so as not to be operated.

Alternatively, the control unit 60, the first temperature range, the second temperature range, the third temperature range and the fourth temperature range (temperature Each of the items included in the ascending order) may determine whether the first heat-providing piece 41 and the second heat-providing piece 42 are activated.

Specifically, the control unit 60, when the temperature value measured by the temperature measuring unit 50 is the first temperature range, the first heat providing piece 41 and the second heat providing piece 42 All of them are operated so that the temperature of the accommodation space and the object to be housed rises relatively quickly, and when the temperature value measured by the temperature measuring unit 50 is the second temperature range, the first heat providing piece (41) is operated, the second heat-provided piece (42) is not operated, so that the temperature of the accommodation space and the object to be risen is relatively fast to rise, measured by the temperature measuring unit (50) When the temperature value is in the third temperature range, the first heat-providing piece 41 is not operated, and the second heat-providing piece 42 is operated to gradually increase the temperature of the accommodation space and the object to be housed. When the temperature value measured by the temperature measuring part 50 is the fourth temperature range, it is possible to prevent both the first heat providing piece 41 and the second heat providing piece 42 from being operated. have.

On the other hand, the mounting portion 331, may be composed of a plurality of mounting pieces that are mounted along the outer circumferential surface of the rotating pillar portion (31).

The extension portion 333 may be composed of a plurality of extension pieces mounted on each of the plurality of mounting pieces.

Any one of the plurality of mounting pieces, the tilting direction with the neighboring mounting pieces may be operated differently.

Accordingly, the plurality of extension pieces are tilted so as to deviate from neighboring extension pieces, so that the object to be housed in the accommodation space can be efficiently mixed.

The plurality of air injection pieces 21 may be formed such that the size of the air blowing force increases relatively as they are disposed closer to the bottom surface of the base portion 10.

This, when the object to be housed is stirred by the stirring part 30, the more the object to be placed disposed close to the bottom surface of the base part 10, the faster it is dropped by the accumulated weight, so air is smoothly flowed into the space between the objects to be built. It is to inflow.

The plurality of extension pieces may be formed to have a relatively thick thickness as they are disposed closer to the bottom surface of the base portion 10.

This is to prevent breakage of the extension piece to stir it, since it is difficult to move by the accumulated weight as the object to be placed is disposed closer to the bottom surface of the base portion 10.
