Description

Technical Field

[0001] This utility model specifically relates to a steam oven for bread processing, belonging to the field of steam oven technology. Background Technology

[0002] A steam oven for bread processing is a device specifically designed for baking bread. It heats and bakes bread using a combination of steam and hot air. The oven typically consists of a heating chamber and a steam generator. The heating chamber holds the bread to be baked, while the steam generator is responsible for generating steam and introducing it into the heating chamber.

[0003] During the operation of a steam oven, when steam continuously flows through the steam pipe and is output to the baking area through the nozzles, it is affected by various factors such as heat dissipation of the steam pipe, ambient temperature fluctuations, insulation design, and pipe design. As a result, the steam is prone to condensation and accumulation of condensate on the pipe wall, causing some of the condensate to drip from the nozzles onto the bread surface, making the bread crust soft and soggy, and damaging its crispness and color. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by providing a steam oven for bread processing. It includes a shell, with a main air inlet pipe installed at the top. A steam shut-off valve and a steam solenoid valve are sequentially installed on the main air inlet pipe, with the solenoid valve positioned close to the shell. Two sets of steam boxes are located at both ends inside the shell, connected by a steam pipe. Multiple sets of steam delivery pipes facing opposite directions are connected to each of the two sets of steam delivery pipes. Steam nozzles are connected between the two ends of each steam delivery pipe. A steam flow regulating valve is installed at the end of each steam delivery pipe near one of the steam boxes. One end of the main air inlet pipe is connected to the middle of the steam pipe. The steam nozzles include an inner tube, with both ends connected to the steam delivery pipes. An outer tube is sealed around the inner tube in the baking area of ​​the shell. The inner tube has multiple sets of upward-facing air delivery nozzles, and the outer tube has multiple sets of downward-facing air jet nozzles, all located within the baking area of ​​the shell.

[0005] The end of each steam delivery pipe away from the steam box is connected to a steam condensate discharge pipe, and a steam trap is installed at the other end of the steam condensate discharge pipe.

[0006] An exhaust fan is also installed on the outside of the housing, and the output end of the exhaust fan is connected to an exhaust pipe, one end of which extends to the bread baking area inside the housing.

[0007] A steam baffle is rotatably arranged between the steam zone and the baking area of ​​the shell, and a drive motor for driving the steam baffle to rotate is also provided inside the shell.

[0008] The end of the steam condensate discharge pipe near the steam trap is detachably connected to a corrugated drain pipe.

[0009] The bottom of the housing has multiple sets of support legs symmetrically installed at the four corners, and the bottom of the support legs is embedded with rubber pads.

[0010] Beneficial effects:

[0011] Steam is introduced by opening the steam shut-off valve, enters the steam pipe through the main air inlet, and is distributed to each group of steam delivery pipes through the steam box. The flow rate of each group is independently adjusted by the steam flow regulating valve to adapt to the baking needs of different breads. Then, the steam enters the outer pipe through the air delivery nozzle of the inner pipe, and finally is evenly sprayed onto the bread surface through the air jet nozzle. The separation design of the inner and outer pipes can effectively isolate condensate and prevent condensate from dripping directly onto the bread and contaminating it. In addition, the steam trap senses the pressure difference in real time and automatically discharges the condensate that flows into the steam condensate discharge pipe. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-6 As shown, a steam oven for bread processing includes a shell 12. An air inlet main 13 is installed at the top of the shell 12. A steam shut-off valve 1 and a steam solenoid valve 2 are sequentially installed on the air inlet main 13. The steam solenoid valve 2 is located close to the shell 12. Two sets of steam boxes 7 are located at both ends inside the shell 12, connected by a steam pipe 3. Multiple sets of steam delivery pipes 5 facing opposite directions are connected to each of the two sets of steam boxes 7. Steam nozzles 4 are connected between the two ends of the steam delivery pipes 5. A steam flow regulating valve 6 is installed at the end of each set of steam delivery pipes 5 near the steam box 7. One end of the air inlet main 13 is connected to the middle of the steam pipe 3. The steam nozzle 4 includes an inner pipe 401, with both ends connected to the steam delivery pipes 5. An outer pipe 402 is sealed around the inner pipe 401 in the baking area of ​​the shell 12. The inner pipe 401 has an opening... Multiple sets of upward-facing air supply nozzles 403 are provided, and multiple sets of downward-facing air jet nozzles 404 are provided on the outer pipe 402. All sets of air jet nozzles 404 are located in the baking area of ​​the shell 12. The shell 12 is the main structure of the oven, and the interior is equipped with a bread baking area and steam baking components. The main air inlet pipe 13 is used to introduce steam, the steam shut-off valve 1 is used to control the steam on and off, the steam solenoid valve 2 is used to precisely control the steam flow rate, the steam box 7 is used to store and distribute the steam delivered from the steam pipe 3, and the steam delivery pipe 5 is used to deliver steam from the steam box 7 to the inner pipe 401. The steam received by the inner pipe 401 is delivered to the interior of the outer pipe 402 through the air supply nozzles 403. The outer pipe 402 sprays steam out through the air jet nozzles 404 and delivers it to the bread surface in the baking area to prevent the accumulated condensation from dripping directly onto the bread surface.

[0021] Furthermore, the end of the steam delivery pipe 5 away from the steam box 7 is connected to a steam condensate discharge pipe 14, and the other end of the steam condensate discharge pipe 14 is equipped with a steam trap 8; the steam condensate discharge pipe 14 is used to collect and discharge the condensate generated in the steam delivery pipe 5 and the inner pipe 401. The steam trap 8 automatically opens the valve to discharge the condensate by sensing the pressure difference between the steam and the condensate. After the condensate is discharged, the steam trap 8 will automatically close to prevent steam leakage.

[0022] Furthermore, an exhaust fan 9 is installed on the outside of the housing 12. The output end of the exhaust fan 9 is connected to an exhaust pipe 10, one end of which extends to the bread baking area inside the housing 12. The exhaust fan 9 generates negative pressure and uses the exhaust pipe 10 to extract excess steam from inside the housing 12, thereby maintaining the stability of the oven's internal environment.

[0023] Furthermore, a steam baffle 11 is rotatably provided between the steam zone and the baking zone of the housing 12, and a drive motor for driving the steam baffle 11 to rotate is also provided inside the housing 12; wherein the steam baffle 11 can be rotated by controlling the drive motor to adjust the angle of the steam baffle 11, control the amount of steam entering the baking zone, and control the steam not entering the baking zone, so as to adapt to the baking and usage requirements of different breads.

[0024] Furthermore, a corrugated drain pipe is detachably connected to the end of the steam condensate discharge pipe 14 near the steam trap 8. The corrugated drain pipe can guide the condensate discharged through the steam trap 8 and discharge it to a designated area.

[0025] Furthermore, multiple sets of support legs are symmetrically installed at the four corners of the bottom of the housing 12, and rubber pads are embedded at the bottom of the support legs; the support legs are used to lift the housing 12 off the ground as a whole and maintain a certain height above the ground, reduce the erosion of the bottom of the housing 12 by ground moisture, and improve the friction between the support legs and the ground by utilizing the anti-slip properties of the rubber pads.

[0026] Operating steps: Start the exhaust fan 9 to expel cold air and moisture from inside the housing 12 through the exhaust pipe 10, preheating the oven environment. Then, open the steam shut-off valve 1 to introduce steam. At this time, the steam enters the steam pipe 3 through the main air inlet pipe 13 and is distributed to each group of steam delivery pipes 5 through the steam box 7. At the same time, according to the type and size of bread, the steam flow rate of each group of steam delivery pipes 5 is independently adjusted by the steam flow regulating valve 6 to ensure that the steam supply meets the baking requirements. When the steam enters the inner pipe 401, the steam will be delivered to the outer pipe 402 through the air delivery nozzle 403. The air jet nozzle 404 on the outer pipe 402 sprays the steam directly onto the bread surface. Due to the separate design of the inner pipe 401 and the outer pipe 402, the condensate collects in the inner pipe 401, preventing it from dripping directly onto the bread surface. During this process, the drain valve 8 automatically senses the pressure difference between the steam and the condensate, and discharges the condensate that flows into the steam condensate discharge pipe 14 from both the steam delivery pipe 5 and the inner pipe 401, and then discharges it to the designated area through the corrugated drain pipe.
