[0002] The production process of fermented black beans typically includes steps such as selecting raw materials, soaking, steaming, cooling, and fermentation. The steaming process is crucial for obtaining a delicious and aesthetically pleasing finished product. The traditional production process involves placing soaked soybeans into a large steamer and steaming them directly. The soybeans are then shoveled onto a transport vehicle for fermentation. This method, which relies on manual shoveling to transport the cooked soybeans, easily causes the soybeans to deform, affecting the appearance and quality of the fermented black beans.

[0003] However, when using a steaming box that can steam a large amount of fermented black beans at once, it is difficult to quickly and conveniently remove the fermented black beans after steaming. Utility Model Content

[0026] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0027] See Figures 1-3 As shown, a steaming device for fermented black beans includes a base 1, a sealing cover 2 is provided on the top of the base 1, sealing side plates 13 are fixedly connected to both sides of the sealing cover 2, an exhaust valve 3 is embedded in the inner side of the sealing cover 2, a sealing plate 4 is fixedly connected to the inner side of the sealing cover 2, a conveyor belt 5 is fixedly provided on the top of the base 1, an inner support frame 6 is embedded in the inner side of the conveyor belt 5, a steam main pipe 7 is provided on the outer side of the inner support frame 6, a steam branch pipe 8 is connected to the inner side of the steam main pipe 7, an outer pipe 9 is connected to the outer side of the steam branch pipe 8, and the steam branch pipe 8 is also embedded in the inner side of the inner support frame 6. A steaming zone 10 is provided on the surface of the conveyor belt 5, a placement tray 11 is embedded in the steaming zone 10, and a guide plate 12 is fixedly connected to the outer side of the steaming zone 10.

[0028] In this embodiment of the utility model, the sealing cover 2 is generally rectangular, with its two lateral ends being rectangular open, and the top of the sealing cover 2 being trapezoidal hollow. Multiple sets of exhaust valves 3 are equidistantly distributed along the top surface of the sealing cover 2 and communicate with the interior of the sealing cover 2. The sealing side plate 13 is generally made of stainless steel rectangular plate with a "Z" shaped side section, located on both longitudinal sides of the sealing cover 2. The bottom end of the sealing side plate 13 is located on the top of the inner support frame 6. Two sets of sealing plates 4 are generally provided, located on both lateral sides of the sealing cover 2, each comprising two sets of interlocking stainless steel... The plate has an internal electric telescopic rod at the joint, and the bottom of the stainless steel plate is equipped with a food-grade silicone rubber layer. The sealing cover 2 achieves the effect of completely surrounding and sealing the conveyor belt 5. The exhaust valve 3, together with the trapezoidal inner cavity of the sealing cover 2, achieves the effect of venting the steam generated during the steaming process. The sealing side plate 13 achieves the effect of surrounding and sealing the conveyor belt 5 from both longitudinal sides. The sealing plate 4 achieves the effect of sealing the conveyor belt 5 from both transverse sides, reducing steam leakage and ensuring the steaming process of the raw materials.

[0029] When steaming external raw materials, the sealing plate 4 is raised and lowered, and its bottom end contacts the transverse two sides of the conveyor belt 5 to form a seal. The longitudinal two sides of the sealing cover 2 are sealed through the contact between the sealing side plate 13 and the inner support frame 6, ensuring that the raw materials on the conveyor belt 5 can receive steam treatment to the maximum extent and avoid excessive steam leakage. After steaming, the exhaust valve 3 is opened to discharge the steam in the sealing cover 2 to the outside.

[0030] The steaming zone 10 is rectangularly recessed, with two groups of two located on the upper and lower surfaces of the conveyor belt 5. The surface of the steaming zone 10 is set with a breathable grid. Four guide plates 12 are set on the outer side of the corners of the steaming zone 10. The inner surface of the guide plate 12 is arc-shaped and convex, and a magnetic layer is provided on its surface. The placement tray 11 is rectangular, and a magnetic layer is provided on its edge corresponding to the guide plate 12. The surface of the placement tray 11 is rectangularly recessed and has honeycomb-shaped breathable holes. The placement tray 11 slides into the inner side of the guide plate 12. The steaming zone 10 facilitates the conveying and output of steam from bottom to top. The guide plate 12 limits and fixes the placement tray 11. The placement tray 11 is used to place external fermented black bean raw materials. The placement tray 11, which is slidably connected to the guide plate 12, can quickly complete the loading and unloading of fermented black bean raw materials.

[0031] The user first places the fermented black bean raw material on the placement tray 11, and then embeds the entire placement tray 11 into the steaming area 10, so that it is embedded in the guide plates 12 around it. The guide plates 12 and the placement tray 11 are magnetically fixed. After placement, the conveyor belt 5 is turned on. The conveyor belt 5 rotates and moves the placement tray 11 to the bottom of the sealing cover 2. Then, external steam is input through the external pipe 9. The steam is transported from bottom to top to the steaming area 10 through the steam branch pipe 8 to steam the raw material in the placement tray 11.

[0032] The inner support frame 6 is set as an "H"-shaped double-layer support, and a connecting bracket is fixed between its outer side and the base 1. The steam main pipe 7 is set horizontally and is connected to the external steam generating mechanism through the outer pipe 9. Multiple sets of steam branch pipes 8 are set vertically and embedded in the inner support frame 6. Steam nozzles are opened on the surface of the steam branch pipes 8. The inner support frame 6 achieves the effect of supporting and limiting the steam branch pipes 8, and the steam branch pipes 8 achieve the effect of conveying steam from bottom to top to the steaming zone 10.

[0033] The external steam generator is activated, and steam is delivered to the main steam pipe 7 and the branch steam pipe 8 through the external pipe 9. Steam is ejected from the steam nozzles on the surface of the branch steam pipe 8, and the fermented black bean raw materials placed in the placement tray 11 are steamed from the bottom.

[0034] Steaming fermented black beans requires precise control of temperature (usually 100-120℃), steam saturation, and steaming time. Therefore, a corresponding testing agency is needed to provide real-time data feedback to avoid undercooking or overcooking. Thus, PT100 platinum resistance thermometers or thermocouples with high temperature resistance and accuracy of ±0.5℃ are respectively installed at the top of the sealing cover 2 and the bottom of the steaming zone 10 in this device.

[0035] Meanwhile, a capacitive humidity sensor with a high-temperature protective shell and a pressure sensor piezoresistive pressure transmitter with a range of 0-0.5MPa are respectively installed on the inner wall and top of the sealing cover 2 near the exhaust valve 3. They can be used for linkage control of the opening and closing of the exhaust valve.

[0036] Meanwhile, a visual inspection device can be optionally installed inside the sealing cover 2. Specifically, a high-temperature resistant industrial camera with a condensation protection lens can be installed to monitor the color and expansion state of the fermented black bean raw material and assist in judging the degree of steaming.

[0037] The sensor cables involved in this device must be fitted with high-temperature resistant silicone sheaths. In addition, anti-interference measures, such as electromagnetic shielding, are implemented to address the potential signal interference from the solenoid valve generated by the steam branch pipe 8.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model, and they should all be covered within the scope of the claims and specification of this utility model.
