[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Example 1

[0030] like Figure 1 , 5 As shown in Figure 6, a steam generator includes a box body 1, a box cover 2, a heating device 3 placed in the box body, and a mounting bracket 11. The box cover 2 is sealed and connected to the box body 1. A steam duct 4 is arranged in the box body 1. The heating device 3 and the steam duct 4 are arranged at intervals. The top end of the steam duct 4 is open and does not abut against the box cover 2. The bottom end of the steam duct 4 is connected to the bottom surface of the box body 1. The mounting bracket 12 is used to install the box body 1 on the food processing machine 11.

[0031] The side wall of the box body 1 is provided with an auxiliary water tank 5 connected thereto, and an inlet pipe 6 and an overflow pipe 7 are arranged in the auxiliary water tank 5. Since the volume of the box body 1 is limited and a large amount of water cannot be stored, the box body 1 and the auxiliary water tank 5 are formed into a communicating vessel by setting an auxiliary water tank 5 whose bottom end is connected to the box body 1. At the same time, an inlet pipe 6 and an overflow pipe 7 are arranged in the auxiliary water tank 5. The water outlet height of the overflow pipe 7 is set, and the inlet pipe 6 is connected to the water pump, which can realize automatic water replenishment and maintain the water level in the box body 1 stable.

[0032] The working principle of this embodiment is as follows: the heating device 3 heats the water in the box body 1 into water vapor. Since a sealed connection is provided between the box body 1 and the box cover 2, the steam cannot overflow. Since the top of the steam pipe 4 is open and does not abut against the box cover 2, the bottom end of the steam pipe 4 is connected to the bottom surface of the box body 1, so that the water vapor in the box body 1 can enter from the top of the steam pipe 4 and be discharged from the bottom of the steam pipe 4, thereby heating the rice noodle rolls located below the steam generator.

[0033] When the water level in the tank 1 reaches a low position, since the tank 1 and the auxiliary water tank 5 form a communicating structure, the water level in the auxiliary water tank 5 also reaches a low position. Water is pumped into the auxiliary water tank 5 through the water inlet conduit and flows into the tank 1 by a water pump to replenish the water in the tank 1. When the water level in the auxiliary water tank 5 reaches a high position (exceeding the pipe mouth of the overflow pipe), the water in the auxiliary water tank 5 will flow out from the overflow pipe 7, thereby ensuring that the water in the tank 1 is always within a specific water level range without the need for manual water addition.

[0034] In other embodiments, Figure 2 As shown, the side wall of the box body 1 is provided with an auxiliary water tank 5 connected thereto, and also includes a float valve 8. The water inlet end of the float valve 8 is provided with a water pipe, and the water outlet is connected to the auxiliary water tank 5. After connecting to tap water, it can automatically replenish water when the water level in the box body 1 is low, so as to maintain the water level in the box body 1 stable.

[0035] Example 2

[0036] like Figure 3 , 4 As shown in Figures 5 and 6, a steam generator comprises a box body 1, a box cover 2, a heating device 3 placed in the box body, and a mounting bracket 11. The box cover 2 is sealed and connected to the box body 1. A steam guide pipe 4 is arranged in the box body 1. The heating device 3 and the steam guide pipe 4 are arranged at intervals. The top end of the steam guide pipe 4 is open and does not abut against the box cover 2. The bottom end of the steam guide pipe 4 is connected to the bottom surface of the box body 1. The mounting bracket 12 is used to install the box body 1 on the food processing machine 11.

[0037] The side wall of the box body 1 is provided with an auxiliary water tank 5 connected thereto, and an inlet pipe 6 and an overflow pipe 7 are provided in the auxiliary water tank 5. The bottom ends of the inlet pipe 6 and the overflow pipe 7 penetrate the auxiliary water tank 5 and are respectively connected with an inlet conduit and an overflow conduit. Since the box body 1 has a limited volume and cannot store a large amount of water, the box body 1 and the auxiliary water tank 5 are formed into a communicating vessel by providing an auxiliary water tank 5 whose bottom end is connected to the box body 1. At the same time, an inlet pipe 6 and an overflow pipe 7 are provided in the auxiliary water tank 5. The water outlet height of the overflow pipe 7 is set properly, and the inlet pipe 6 is connected to a water pump, so that the effect of automatic water replenishment in case of water shortage can be achieved;

[0038] It also includes a cover 9, which is connected to the steam guide pipe 4. By adding the cover 9, the contact area between the steam and the food can be expanded, that is, the steam coverage range is increased, and the food heating efficiency is improved.

[0039] Furthermore, a spoiler 13 is provided on the cover 9, and its main function is to improve the steam cooking effect, so that the steam is sprayed toward the conveyor belt, which is better than the effect of the steam flowing parallel to the conveyor belt. The spoiler 13 also plays the role of reinforcing the cover.

[0040] Furthermore, a silicone strip 10 is provided on the protruding edge of the cover 9. The provision of the silicone strip 10 is beneficial to improving the sealing between the cover 9 and the conveyor belt 11 in the food processing machine, further improving the steam heating effect; in addition, during the production process, water vapor will cause water on the conveyor belt of the food processing machine 11, and the water and the silicone strip can further play a sealing role.

[0041] The working principle of this embodiment is as follows: the heating device 3 heats the water in the box body 1 into water vapor. Since the box body 1 and the box cover 2 are sealed, the steam cannot overflow. Since the top of the steam pipe 4 is open and does not abut against the box cover 2, the bottom of the steam pipe 4 is connected to the bottom surface of the box body 1, so that the water vapor in the box body 1 can enter from the top of the steam pipe 4 and be discharged from the bottom of the steam pipe 4, thereby heating the rice noodle rolls located below the steam generator.

[0042] When the water level in the tank 1 reaches a low position, since the tank 1 and the auxiliary water tank 5 form a communicating structure, the water level in the auxiliary water tank 5 also reaches a low position. Water is pumped into the auxiliary water tank 5 through the water inlet conduit and flows into the tank 1 by a water pump to replenish the water in the tank 1. When the water level in the auxiliary water tank 5 reaches a high position (exceeding the pipe mouth of the overflow pipe), the water in the auxiliary water tank 5 will flow out from the overflow pipe 7, thereby ensuring that the water in the tank 1 is always within a specific water level range without the need for manual water addition.

[0043] In other embodiments, Figure 2 As shown, the side wall of the box body 1 is provided with an auxiliary water tank 5 connected thereto, and also includes a float valve 8. The water inlet end of the float valve 8 is provided with a water pipe, and the water outlet is connected to the auxiliary water tank 5. After connecting to tap water, it can automatically replenish water when the water level in the box body 1 is low, so as to maintain the water level in the box body 1 stable.

[0044] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
