There is a gap with a circular cross section between the oxygen distributor plate 3 and the oxygen outlet pipe 11, and the oxygen distributor plate 3 is flush with the lower end surface of the oxygen outlet pipe 11.

[0022] Compared with the prior art, the burner for the gas roaster provided by the present invention has a plurality of gas outlet pipes 21 in the gas channel, so that the roasting area of ​​the burner is larger and the roasting time is reduced; the conical oxygen distributor plate 3 is coaxially fixed in the oxygen outlet pipe 11 and the oxygen distributor plate 3 is flush with the lower end surface of the oxygen outlet pipe 11, so that the oxygen in the oxygen outlet pipe 11 is uniformly dispersed to the outside along the annular gap in the cross section between the oxygen distributor plate 3 and the oxygen outlet pipe 11, and the oxygen outlet pipe 11 is evenly distributed around the periphery, so that all the gas outlet pipes 21 are evenly roasted after ignition, and the oxygen coming out of the oxygen outlet pipe 11 is directed to float toward the gas outlet pipe 21, so that the flame of the gas coming out of the gas outlet pipe 21 is stronger, so the roasting time is further reduced. In summary, the present invention solves the problem of long roasting time caused by the existing burner.

[0023] As a specific embodiment of the burner for a gas roaster provided by the present invention, please refer to Figure 3The gas channel also includes a gas inlet pipe 22.

The sealing plug 92 is arranged in the pressure relief pipe 91 and is sealed and slidably connected with the pressure relief pipe 91. The middle part of the sliding column 93 coaxially slides through the closed end of the pressure relief pipe 91. The end of the sliding column 93 located outside the pressure relief pipe 91 has a radially protruding limit portion 931, and the other end is fixedly connected with the sealing plug 92. The compression spring 94 is arranged in the pressure relief pipe 91 and is sleeved on the sliding column 93. The two ends of the compression spring 94 squeeze the pressure relief pipe 91 and the sealing plug 92 respectively. The sliding of the sealing plug 92 is used to realize the connection and disconnection between the heat dissipation cavity and the long hole 911. When the pressure in the heat dissipation cavity is relatively high, the sealing plug 92 moves outward, and the heat dissipation cavity is connected with the long hole 911, so that the pressure in the heat dissipation cavity can be reduced. When the pressure in the heat dissipation cavity is reduced, the sealing plug 92 moves inward, and the connection between the heat dissipation cavity and the long hole 911 is disconnected.
