Description

Technical Field

[0001] This utility model relates to the field of steaming bun platform technology, specifically to a layered energy-saving steaming bun platform. Background Technology

[0002] A steaming station is a commercial kitchen appliance specifically designed for the efficient steaming and heat preservation of steamed buns and other bread-like foods. It features a built-in steam system (gas or electric drive) that generates sufficient steam in a short time, supporting the simultaneous steaming of multiple steamers. Designs include double-hole, triple-hole, or multi-hole options to meet batch production needs. The entire outer shell is made of 304 stainless steel, making it corrosion-resistant and easy to clean. When steaming buns, several buns can be placed in stacked steamers, allowing steam to rise through the gaps at the bottom of the steamers, enabling simultaneous steaming of buns in multiple layers. However, existing technologies have the following limitations:

[0003] Because the existing stainless steel panels on the top of steaming tables are prone to dents after long-term use, water can easily accumulate during use. If not cleaned in time, this can lead to hygiene problems and affect food safety and hygiene. However, the drainage efficiency of the accumulated water is not high, and the residual water often needs to be cleaned manually, which is inconvenient. At the same time, the existing steaming tables mainly steam the buns by stacking the steaming baskets at the steam outlet. The steam mainly flows upward between the steaming baskets, causing a large amount of steam to flow directly out from the gaps between the steaming baskets, resulting in steam waste. This means that more steam is needed to steam buns, indirectly increasing energy consumption. Utility Model Content

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] like Figure 1 , Figure 2As shown, this utility model provides a layered energy-saving steaming platform, including a steaming platform body 1. Four sealing steaming mechanisms 2 are arranged in a rectangular array on the top of the steaming platform body 1. Four through holes 11 are opened in the rectangular array on the top of the steaming platform body 1, penetrating its inner cavity. An inverted conical funnel 12 is fixedly installed below the inner ring of each of the four through holes 11. A steam conveying pipe 123 is fixedly connected to the bottom of each of the four inverted conical funnels 12. A steam water tank 17 is fixedly installed at the bottom of the inner wall of the steaming platform body 1. A heating power supply 171 is fixedly installed on the left side of the steam water tank 17. The bottom ends of the four steam conveying pipes 123 all penetrate into the inner cavity of the steam water tank 17. A steam outlet pipe 121 penetrating into the inner cavity of each of the four steam conveying pipes 123 is fixedly connected to the top of each of the four steam conveying pipes 123. The opposite faces of the two inverted conical funnels 12 at the front and rear are fixedly connected and penetrate each other. The steam steamer has a drain pipe 122 in its inner cavity, and a water collection pipe 13 is fixedly connected to the end of the four drain pipes 122 away from the inverted conical funnel 12.

The outer frame of the filter plate 143 is located to the left of the cleaning port 18. An observation hole penetrating its inner cavity is provided on the right side of the water storage box 15. A visualization glass window 151 is fixedly installed on the inner side of the observation hole. The visualization glass window 151 is located to the left of the visualization port 19.

[0027] When water enters the inner cavity of the filter box 14, it can be filtered through the stainless steel screen 144 on the inner side of the filter plate outer frame 143, which is snapped into the slot 141. When cleaning is required, simply use the pull handle 146 to pull the entire filter plate outer frame 143 out to the outside through the cleaning port 18. During installation, simply align the filter plate outer frame 143 with the slot 142 and snap it into the inner side of the slot 141 until the rubber ring 145 on the outer wall of the filter plate outer frame 143 is firmly snapped into the inner ring of the slot 142 to complete the installation. The water level in the inner cavity of the water storage box 15 can be displayed at any time through the visualization glass window 151. Operators can observe the visualization glass window 151 through the visualization port 19 at any time, and conveniently control the water pump 16 to start and drain the water from the inner cavity of the water storage box 15.

[0028] like Figure 4 , Figure 5As shown, the sealed steaming mechanism 2 includes a bottom steamer 21, two middle steamers 22 are snapped onto the top of the bottom steamer 21, and a top steamer 23 is snapped onto the top of the middle steamers 22. A retaining pipe 24 penetrating the inner cavity is fixedly installed at the bottom of the bottom steamer 21. The retaining pipes 24 at the bottom of the four bottom steamers 21 are respectively snapped onto the inner ring of four through holes 11. Four support legs 25 are fixedly installed in a rectangular array at the bottom of the bottom steamer 21. Lifting grooves 211 are provided on the left and right sides of the bottom steamer 21, middle steamers 22, and top steamer 23. Glass flip covers 212 are hinged to the front of the bottom steamer 21, middle steamers 22, and top steamer 23. The bottom of the inner ring of the top steamer 23 is fixedly installed with... The middle steamer 22 is equipped with an air intake grille 231, and the bottom of the inner ring of the middle steamer 22 is fixedly installed with an air intake grille 221. The inner ring of the clamping pipe 24 is fixedly installed with an air intake grille 241. The top steamer 23 is equipped with an air outlet valve 232. The bottom of the top steamer 23 and the two middle steamers 22 are all fixedly installed with directional clamping frames 233, and the outer wall of the directional clamping frames 233 is fixedly bonded with a sealing rubber ring 234. The top steamer 23 is clamped to the inner ring of the upper middle steamer 22 using the directional clamping frames 233. The upper middle steamer 22 is clamped to the inner ring of the lower middle steamer 22 using the directional clamping frames 233. The lower middle steamer 22 is clamped to the inner ring of the bottom steamer 21 using the directional clamping frames 233.

[0029] The bottom steamer 21 of the sealed steaming mechanism 2 can be connected to the through hole 11 via the snap-fit ​​pipe 24 to prevent steam leakage. Simultaneously, the supporting legs 25 at the bottom of the bottom steamer 21 can elevate it, facilitating the opening of the glass flip-top 212 on the front of the bottom steamer 21. When steaming buns, the entire steamer can be flipped open, and the glass flip-tops 212 on the front of the bottom steamer 21, middle steamer 22, and top steamer 23 can be placed inside. Steam can enter the inner cavity of the bottom steamer 21 through the air inlet grille 3 241, then through the air inlet grille 1 221 into the inner cavity of the middle steamer 22, and finally through the air inlet grille 231 into the inner cavity of the top steamer 23. Excess steam can be discharged outdoors through the exhaust valve 232. Meanwhile, the bottom steamer... 21. The middle steamer 22 and the top steamer 23 can be aligned and snapped together by the directional snap-fit ​​frame 233, and the sealing rubber ring 234 improves the sealing between them after snapping, ensuring that steam does not leak out to the maximum extent, allowing the steam to be more concentrated for steaming the buns, improving steaming efficiency and achieving energy saving. The bottom steamer 21, the middle steamer 22, and the top steamer 23 can all be lifted and disassembled upwards by the lifting groove 211, which is convenient for disassembly and cleaning after steaming. At the same time, the snap-fit ​​pipe 24 that connects to the through hole 11 can allow condensate to be concentrated and discharged into the inner cavity of the inverted conical funnel 12. The glass flip-tops 212 included in the two front sealing steaming mechanisms 2 and the two rear sealing steaming mechanisms 2 face opposite directions, which does not affect opening.

[0030] The working principle of this tiered energy-saving steamer will be explained in detail below.

[0031] like Figure 1-5As shown, during use, the heating rod inside the steam water tank 17 is heated by activating the externally powered heating power supply 171. This causes the water added to the inner cavity of the steam water tank 17 through the covered water inlet pipe 172 to boil in advance, generating a large amount of steam. The steam then enters the steam outlet pipe 121 inside the inverted conical funnel 12 through the steam delivery pipe 123, and exits from the holes on the steam outlet pipe 121, thus entering the inner cavity of the sealed steaming mechanism 2 to steam the buns. At the same time, the condensate generated in the inner cavity of the sealed steaming mechanism 2 can flow directly into the inner cavity of the inverted conical funnel 12 through the through hole 11, and is collected by the drain pipe 122 into the water collection pipe 13, thus being transported to the inner cavity of the filter box 14. After being filtered by the filter box 14, the condensate is ready for steaming. The water can flow directly into the inner cavity of the water storage box 15, and the water source in the inner cavity of the water storage box 15 can be injected into the steam water tank 17 for recycling by starting the water pump 16. At the same time, the side of the steam water tank 17 that comes into contact with the water storage box 15 can be made of heat-conducting stainless steel, so that the residual heat of the hot water in the steam water tank 17 can be transferred to the inner cavity of the water storage box 15 to preheat the water source in the inner cavity of the water storage box 15, saving the time of re-boiling. At the same time, when the water source enters the inner cavity of the filter box 14, it can be filtered through the stainless steel screen 144 on the inner side of the filter plate outer frame 143 that is snapped in the slot 141. When cleaning is required, simply use the pull handle 146 to pull the entire filter plate outer frame 143 out to the outside through the cleaning port 18. During installation, simply remove the filter plate outer frame 143. Align the slot 142 with the inner side of the slot 141 and insert it until the rubber ring 145 on the outer wall of the filter plate frame 143 is firmly engaged with the inner ring of the slot 142. The water level in the inner cavity of the water storage box 15 can be displayed at any time through the visual glass window 151. The operator can observe the visual glass window 151 through the visual port 19 at any time, and easily control the water pump 16 to start and discharge the water in the inner cavity of the water storage box 15. The bottom steamer 21 included in the sealed steaming mechanism 2 can be connected to the through hole 11 by the snap-fit ​​pipe 24 to prevent steam from leaking out. At the same time, the supporting legs 25 at the bottom of the bottom steamer 21 can raise the bottom steamer 21, making it easy to flip the glass cover 212 on the front side of the bottom steamer 21 forward and open it when steaming buns. After the steamer basket is flipped open, the glass flip-tops 212 on the front of the bottom steamer 21, middle steamer 22, and top steamer 23 are placed inside. Steam can enter the inner cavity of the bottom steamer 21 through the third air inlet grille 241, then enter the inner cavity of the middle steamer 22 through the first air inlet grille 221, and finally enter the inner cavity of the top steamer 23 through the second air inlet grille 231. Excess steam can be discharged outdoors through the exhaust valve 232. At the same time, the bottom steamer 21, middle steamer 22, and top steamer 23 can be aligned and locked together by the directional locking frame 233, and the sealing rubber ring 234 improves the sealing between them after locking, ensuring that steam does not leak out to the maximum extent, allowing the steam to be more concentrated for steaming the buns, improving steaming efficiency and achieving energy saving.Furthermore, the bottom steamer 21, the middle steamer 22, and the top steamer 23 can all be lifted and disassembled via the lifting groove 211, facilitating disassembly and cleaning after steaming.

[0032] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
