Abstract
Description
Technical Field
[0001] This utility model relates to the field of instant noodle production technology, specifically to a steamer insulation mechanism for instant noodle production. Background Technology
[0002] The main function of an instant noodle steamer is to steam the shaped noodles, thereby improving their crispness and nutritional value. Specifically, the steamer works by placing the instant noodle ingredients on a rack and activating the device, allowing the noodles to be heated evenly within the steamer until cooked.
[0003] The existing Chinese utility model patent with publication number CN215051261U discloses a heat preservation device for a vacuum setting machine steam chamber. The device includes casters, a support frame fixedly connected to the top of the casters, an outer shell fixedly mounted on the top of the support frame, an insulation layer fixed to the inner wall of the outer shell, and a pad fixedly connected to the inner wall of the insulation layer. An installation hole is provided on the side of the outer shell, and an extraction pipe is fixedly connected to the inner wall of the installation hole. An extraction pump is movably connected to the end of the extraction pipe, and an exhaust pipe is movably connected to the side of the extraction pump. This heat preservation device for a vacuum setting machine steam chamber, through its heat insulation layer and foam filling layer, prevents the internal heat of the steam chamber from easily escaping during yarn steaming, thus reducing steaming time and production costs for the user. The metal protective layer prevents damage to the insulation layer when workers load yarn into the steam chamber, increasing the service life of the insulation layer to some extent.
[0004] Existing insulation structures generally achieve their insulation effect through insulation materials, which typically include high-density fiberboard, fiberglass yarn, volcanic rock, and other insulation materials. However, this method still results in some heat loss through the insulation materials. Furthermore, the insulation effect of existing insulation materials will continue to decline over time. Moreover, most existing insulation structures are fixed, making it impossible to replace the insulation materials after they reach their service life, resulting in high maintenance costs.

[0009] As a preferred embodiment of this utility model, the outer edge of the sealing plate is fixedly connected to the front end of the outer shell, the inner edge of the sealing plate is fixedly connected to the front end of the heat-insulating inner liner, and the door is movably installed on the front side of the outer shell via a hinge; the heat-insulating inner liner can play a heat-insulating role.
[0010] As a preferred embodiment of this utility model, the door is movably connected to the cover plate via connecting bolts, and the spring is located between the cover plate and the connecting bolts;
[0011] As a preferred embodiment of this utility model, the low-pressure plate is fixedly installed on the upper, lower, left, right and rear sides of the outer shell, and the low-pressure plate is located between the outer shell and the inner heat-insulating liner; the low-pressure plate can play a heat-insulating role.
[0012] As a preferred embodiment of this utility model, the low-pressure plate is connected to the connecting pipe through an exhaust pipe, and the support frame is installed equidistantly inside the low-pressure plate; the exhaust pipe facilitates the discharge of air from inside the low-pressure plate.
[0013] As a preferred embodiment of this utility model, the two ends of the support frame are fixedly connected to the top and bottom surfaces of the low-pressure plate, respectively, and the steam pipe passes through the outer shell and the heat-insulating inner liner; the support frame can provide support for the low-pressure plate.
[0014] As a preferred embodiment of this utility model, the vacuum pump is connected to the rear end of the solenoid valve via a bend, and the bend is connected to the connecting pipe via the solenoid valve; the solenoid valve can prevent air from flowing back into the connecting pipe.
[0015] Compared with the prior art, this utility model provides a steamer insulation mechanism for instant noodle production, which has the following beneficial effects:
[0016] 1. This utility model utilizes a low-pressure plate, which is fixedly installed on the top, bottom, left, right, and rear sides of the outer shell, and is located between the outer shell and the inner insulation liner. The low-pressure plate is connected to the connecting pipe through an exhaust pipe. The support frame is installed equidistantly inside the low-pressure plate, with both ends fixedly connected to the top and bottom surfaces of the low-pressure plate. After the internal air is extracted from the low-pressure plate, the force on both sides is transmitted to the support frame. The support frame restricts the deformation of the low-pressure plate, preventing it from collapsing. After the internal air is extracted from the low-pressure plate, due to the reduction of the heat transfer medium, the heat inside the low-pressure plate will be difficult to transfer to the other side, thereby improving the insulation effect.
[0017] 2. This utility model incorporates a vacuum pump, which is connected to the rear end of a solenoid valve via a bend in the pipe. The bend in the pipe is connected to a connecting pipe via the solenoid valve, and the front end of the connecting pipe is connected to the inner cavity of a low-pressure plate via an exhaust pipe. When the solenoid valve is opened and the vacuum pump is started, it can extract the air from inside the low-pressure plate. Once the low-pressure plate reaches the low-pressure standard, the solenoid valve wall and the inside of the low-pressure plate will remain in a low-pressure state, thereby maintaining the heat preservation effect. Subsequent maintenance only requires periodically checking the air pressure inside the low-pressure plate and performing the evacuation operation again when the air pressure exceeds the threshold standard. This method facilitates subsequent maintenance. Attached Figure Description

[0026] Please see Figure 1 - Figure 4 In this embodiment, a steamer insulation mechanism for instant noodle production includes: an outer shell 1; a sealing plate 11 fixedly installed at the front end of the outer shell 1; a hinge 12 fixedly installed on the left side of the sealing plate 11; a door 13 fixedly installed at the front end of the hinge 12; a cover plate 14 movably installed on the front side of the door 13; a connecting bolt 15 inserted through the front side of the cover plate 14; a spring 16 inserted through the outside of the connecting bolt 15; an insulation plate 17 fitted inside the cover plate 14; and a low-temperature insulation plate 17 fixedly installed inside the outer shell 1. The pressure plate 18 has a support frame 19 fixedly installed inside it. An exhaust pipe 110 is fixedly installed on the left side of the low pressure plate 18. An insulated inner liner 111 is fixedly installed inside the low pressure plate 18. Steam pipes 112 are inserted through the four corners of the insulated inner liner 111. A connecting pipe 113 is fixedly installed at the rear end of the exhaust pipe 110. A solenoid valve 114 is fixedly installed at the rear end of the connecting pipe 113. A bend 115 is fixedly installed at the rear end of the solenoid valve 114. A vacuum pump 116 is fixedly installed at the lower end of the bend 115.
[0027] The outer edge of the sealing plate 11 is fixedly connected to the front end of the outer shell 1, and the inner edge of the sealing plate 11 is fixedly connected to the front end of the heat-insulating inner liner 111. The door 13 is movably installed on the front side of the outer shell 1 through the hinge 12. The door 13 is movably connected to the cover plate 14 through the connecting bolt 15. The spring 16 is located between the cover plate 14 and the connecting bolt 15. The low-pressure plate 18 is fixedly installed on the upper, lower, left, right and rear sides of the outer shell 1, and the low-pressure plate 18 is located between the outer shell 1 and the heat-insulating inner liner 111. The low-pressure plate 18 is connected to the connecting pipe 113 through the exhaust pipe 110. The support frame 19 is equidistantly installed inside the low-pressure plate 18, and its two ends are fixedly connected to the top and bottom surfaces of the low-pressure plate 18 respectively. The steam pipe 112 passes through the outer shell 1 and the heat-insulating inner liner 111. The vacuum pump 116 is connected to the rear end of the solenoid valve 114 through the bend pipe 115. The bend pipe 115 is connected to the connecting pipe 113 through the solenoid valve 114.
[0028] Specifically, the outer shell 1 protects the low-pressure plate 18, the sealing plate 11 seals the opening at the front of the outer shell 1 and the insulation liner 111, the door 13 is fixedly connected to the outer shell 1 via a hinge 12 to facilitate rotation of the door 13, the cover plate 14 restricts the position of the insulation plate 17, the connecting bolt 15 restricts the position of the front end of the spring 16, and after the connecting bolt 15 is tightened, the position of the front end of the spring 16 is restricted. By compressing the spring 16, the elastic force generated by the compressed spring 16 presses the cover plate 14 against the front of the door 13 to restrict the position of the insulation plate 17. The low-pressure plate 18 is protected by the internal air... After being extracted, the forces on both sides are transmitted to the support frame 19. The support frame 19 restricts the deformation of the low-pressure plate 18 and prevents the low-pressure plate 18 from collapsing. After the air inside the low-pressure plate 18 is extracted, due to the reduction of the heat transfer medium, the heat inside the low-pressure plate 18 will be difficult to transfer to the other side of the low-pressure plate 18. The steam pipe 112 can be located at the angle between the low-pressure plates 18 to deliver high-temperature steam into the heat-insulating inner liner 111. The connecting pipe 113 can facilitate the vacuum pump 116 to extract the air inside the low-pressure plate 18 through the exhaust pipe 110. The bend 115 can facilitate the connection between the vacuum pump 116 and the connecting pipe 113.
[0029] In use, the low-pressure plate 18 is fixedly installed on the top, bottom, left, right, and rear sides of the outer shell 1, and is located between the inner insulation liner 111 of the outer shell 1. The low-pressure plate 18 is connected to the connecting pipe 113 through the exhaust pipe 110. The support frame 19 is equidistantly installed inside the low-pressure plate 18, and its two ends are fixedly connected to the top and bottom surfaces of the low-pressure plate 18, respectively. After the internal air of the low-pressure plate 18 is extracted, the force on both sides is transmitted to the support frame 19. The support frame 19 restricts the deformation of the low-pressure plate 18 and prevents it from collapsing. After the internal air of the low-pressure plate 18 is extracted, due to the reduction of the heat transfer medium, the heat inside the low-pressure plate 18 will be difficult to transfer to the other side of the low-pressure plate 18, thereby improving heat transfer efficiency. For insulation, the vacuum pump 116 is connected to the rear end of the solenoid valve 114 via the bend 115. The bend 115 is connected to the connecting pipe 113 via the solenoid valve 114. The front end of the connecting pipe 113 is connected to the inner cavity of the low-pressure plate 18 via the exhaust pipe 110. When the solenoid valve 114 is opened and the vacuum pump 116 is started, the air inside the low-pressure plate 18 can be extracted. After the low-pressure plate 18 reaches the low-pressure standard, the solenoid valve 114 and the inside of the low-pressure plate 18 will remain in a low-pressure state, thereby maintaining the insulation effect. Subsequent maintenance only requires periodically checking the air pressure inside the low-pressure plate 18. When the air pressure is higher than the threshold standard, the air extraction operation can be repeated. This method facilitates subsequent maintenance.
