Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to a water recovery structure for a corn harvester and a corn harvester. Background Technology

[0002] Corn steaming equipment (hereinafter referred to as "corn machine") is widely used in food processing and catering industries for heating and cooking fresh corn. Existing corn machines on the market generally include an electric heating device, a steamer, and a steaming basket. In use, the corn to be processed is placed on the support layer inside the steaming basket. After adding an appropriate amount of tap water to the steamer, the electric heating device heats the water in the steamer to boiling, generating high-temperature steam. The high-temperature steam enters the steaming basket and coats the corn, allowing it to be heated evenly and gradually cooked through heat transfer.

[0003] During steaming, some of the high-temperature steam diffuses into the external space of the steamer due to thermal pressure, while the rest condenses on the inner wall of the steamer or the surface of the corn, forming condensate. This condensate usually contains coloring substances, soluble sugars, and characteristic odor molecules from the corn, and drips back into the steamer along the steamer wall, gradually contaminating the water in the steamer. As the steaming process continues, the evaporation, condensation, and recirculation of steam repeat continuously, gradually deepening the color and odor of the water in the steamer, ultimately affecting the purity of the steam and its heat transfer efficiency.

[0004] Circulating contamination not only affects the flavor of steamed corn, making it difficult to maintain its original fresh and fragrant taste, but it can also reduce the overall hygiene quality of cooking, and even produce off-flavors or deposit impurities. Therefore, how to effectively prevent the condensate containing the color and odor of corn from flowing back into the steamer, and keep the heating water in the steamer clean, thereby ensuring the original flavor of the corn and the safety of cooking, has become an urgent problem to be solved by existing corn-making machine technology. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a corn harvester water recycling structure and a corn harvester. By setting a structural design that separates the condensate collection and steam channel, the condensate containing the color and smell of corn generated in the steamer is prevented from flowing back into the steamer, thereby keeping the heating water in the steamer clean and ensuring the original flavor of the corn and the hygiene and safety of cooking.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A water recycling structure for a corn harvester includes a steamer, a steaming basket, and a wastewater collection box. The bottom of the steaming basket is provided with a support layer, on which multiple steam passages with upwardly protruding walls are distributed. At least one drain hole is opened around the perimeter of the support layer. The wastewater collection box is provided below the steaming basket. The wastewater collection box has a vertically penetrating steam channel, or a steam channel is formed between multiple wastewater collection boxes, between the wastewater collection box and the steamer, or between the wastewater collection box and the side wall of the steaming basket. Steam generated by the steamer enters the steaming basket through the steam channel.

[0007] First, a wastewater collection box structure is designed, with an independent wastewater storage chamber and a steam passage inside, which are spatially isolated from each other. The wastewater storage chamber is used to collect condensate discharged from the steamer, while the steam passage is used to guide the high-temperature steam generated by the steamer into the steamer. This design completely separates the condensate and steam in their physical paths, preventing the possibility of condensate flowing back into the steamer.

[0008] Secondly, the design of the support layer plays a crucial role in this invention. The steam passages on the support layer form a flow-guiding structure through the upwardly protruding extension walls, effectively preventing condensate from flowing back into the steam channel along the hole walls. Simultaneously, the drain holes around the support layer are located above the wastewater storage chamber of the wastewater collection box, allowing condensate to quickly flow into the wastewater storage chamber through the drain holes, reducing the residence time of condensate in the steamer.

[0009] Furthermore, this invention incorporates a drainage trough along the circumference of the supporting layer, with the drainage holes located at the bottom of the trough. The drainage trough is formed by a downward indentation from the outer edge of the supporting layer and is arranged continuously or intermittently along the circumference of the supporting layer. This design allows condensate to quickly collect in the drainage trough and flow into the wastewater storage chamber through the drainage holes, improving the condensate discharge efficiency.

[0010] This application features an optimized design for the wastewater collection box. The wastewater collection box has outwardly extending overlapping structures around its perimeter for attaching to a steamer. These overlapping structures not only provide a fixing function but also achieve a tight seal to prevent steam leakage. The steam passage of the wastewater collection box is located in the center, and the wastewater storage chamber is arranged continuously or intermittently around the outer edge of the steam passage, and is located at least below the drain hole. This layout ensures that the steam passage and the wastewater storage chamber do not interfere with each other spatially, while also facilitating the centralized collection of condensate.

[0011] The wastewater collection box includes a reinforcing plate to enhance the structural strength of the wastewater storage chamber, which is located on the outside of the reinforcing plate. The steam outlet is located on the reinforcing plate. The reinforcing plate and the load-bearing layer of the steamer are spaced apart to maintain an appropriate distance, allowing steam to smoothly enter the steamer through the steam channel. The steam channel consists of one or more steam outlets, which are staggered with the steam through-holes. This design prevents condensed wastewater dripping from the steam through-holes from flowing into the steamer through the steam outlets, ensuring that all condensed wastewater from the steamer flows into the wastewater storage chamber.

[0012] This utility model also provides a corn harvester, including a base and the aforementioned corn harvester water recycling structure. A heating block is disposed between the base and the steamer. The heating block heats the water in the steamer to boiling point via an electric heating device, generating high-temperature steam. The steam enters the steamer through the steam channel of the wastewater collection box, enveloping the corn and gradually cooking it through heat transfer. The condensate generated in the steamer flows into the wastewater storage chamber of the wastewater collection box through the drain holes of the supporting layer, preventing the condensate from flowing back into the steamer.

[0013] In practical implementation, the wastewater collection box has a first horizontally extending side around its perimeter, and a second upwardly bent extending side outside the first extending side. In operation, the wastewater collection box overlaps the steamer via the first extending side, ensuring a tight seal. This also facilitates the placement and removal of the wastewater collection box, allowing for the pouring out of the collected condensed wastewater.

[0014] The bottom of the steamer has a third extended edge that extends horizontally outward around its perimeter. This third extended edge overlaps the first extended edge of the sewage collection box, further enhancing the seal between the steamer and the sewage collection box.

[0015] This utility model provides a corn-making machine with a water recovery structure and a corn-making machine that, through the setting of a sewage collection box, a supporting layer, and a sewage discharge trough, achieves physical separation of condensate and steam, preventing condensate from flowing back into the steamer. This design not only simplifies the equipment structure but also improves the efficiency of condensate discharge, ensuring the cleanliness of the heating water in the steamer, thereby improving the steaming quality of the corn and the hygiene and safety of cooking.

[0016] Compared with the prior art, this application has the following beneficial effects: 1. The wastewater collection box has outwardly extending overlapping structures around its perimeter. These structures are used to secure the wastewater collection box above the steamer or to overlap the upper part of the lower steamer among two adjacent steamers. This design allows the corn harvester to flexibly adapt to the needs of multi-layer steamers while facilitating the disassembly and cleaning of the wastewater collection box. The top outer side of the wastewater collection box has a first extending edge that fits tightly against the bottom of the steamer to prevent steam leakage or condensate overflow.

[0017] 2. The separation design between the steam channel and the sewage storage chamber of the sewage collection box ensures the unobstructed flow of steam while preventing condensate from entering. The overlapping structure design of the sewage collection box not only improves the sealing performance of the equipment but also facilitates daily maintenance and cleaning operations for users.

Detailed Implementation

[0021] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0022] Example 1: Combination Figure 1-3 As shown, the structure includes a base 4 at the bottom and a corn harvester water recycling structure located above the base. A cast aluminum heating element 41 and a four-sided enclosed outer frame 42 are fixedly connected to the base 4. The cast aluminum heating element 41 can be a heating block or a heating plate.

[0023] The corn harvester's water recovery structure includes steamers 1 and 2, and a steamer basket 3. Steamer 1 rests flat on the heating element 41, and an outer frame 42 surrounds steamer 3, providing front-to-back and lateral restraint and protection. A wastewater collection box 2 is located between steamer 1 and steamer basket 3. The wastewater collection box 2 has wastewater storage chambers 21 around its perimeter and a central section 5. The wastewater storage chambers 21 collect condensate draining from steamer basket 3, while the steam channel 5 guides the high-temperature steam generated by steamer 1 into steamer basket 3. This design prevents condensate from flowing back into steamer 1 through physical path separation.

[0024] The bottom of the steamer 3 is provided with a support layer 31, on which multiple steam passages 311 with upwardly protruding extension walls are distributed. These steam passages 311 form a flow guiding structure through the upwardly protruding extension walls, which can effectively prevent condensate from flowing back into the steam channel 5 along the hole walls. At least one drain hole 312 is provided around the periphery of the support layer 31 for quickly draining the condensate generated in the steamer 3. The steam channel 5 is located in the middle of the wastewater collection box 2 and has a through structure, while the wastewater storage chamber 21 is arranged around the steam channel 5 and is located at least below the drain hole 312. This layout ensures that the steam channel 5 and the wastewater storage chamber 21 do not interfere with each other spatially, while facilitating the centralized collection of condensate.

[0025] To further improve the efficiency of condensate drainage, a drain trough 313 is provided at the bottom of the support layer 31, with a drain hole 312 located at the bottom of the drain trough 313. The drain trough 313 is arranged continuously or intermittently along the circumference of the support layer 31 and is formed by a downward indentation from the outer edge of the support layer 31. This design allows condensate to quickly collect in the drain trough 313 and flow into the wastewater storage chamber 21 through the drain hole 312.

[0026] The enlarged view of the bottom of the steamer 3 highlights the positional relationship between the outer side of the support layer 31 and the drain holes 312. The outer side of the support layer 31 has a downwardly recessed drain trough 313 with multiple drain holes 312 at its bottom. When condensate flows along the surface of the support layer 31, it quickly converges into the drain trough 313 and flows into the wastewater storage chamber 21 through the drain holes 312. This design significantly shortens the residence time of condensate in the steamer 3, reducing the impact of condensate on the internal environment of the steamer 3.

[0027] The wastewater collection box 2 has a first horizontally extending edge 24 around its perimeter, and a second vertically extending edge 25 extending upwards from the outer side of the first extending edge 24. In operation, the wastewater collection box 2 overlaps the steamer 1 via the first extending edge 24, ensuring a tight seal. This also facilitates the placement and removal of the wastewater collection box 2 for emptying collected condensed wastewater or cleaning the box. The bottom of the steamer 3 has a third horizontally extending edge 32 around its perimeter, which overlaps the first extending edge 24 of the wastewater collection box 2, further enhancing the seal between the steamer 3 and the wastewater collection box 2.

[0028] When the corn-making machine is working, the corn to be steamed is placed on the support layer 31 of the steamer 3. The water in the steamer 1 is heated to boiling by the heating element 41. The generated high-temperature steam enters the steamer 3 through the steam channel 5 and steam vent 311, wrapping the corn placed on the support layer 31. Through the heat transfer of the steam, the corn gradually cooks. The high-temperature steam comes into contact with the inner wall of the steamer 3 and the surface of the corn. The steam lid will condense into small liquid water droplets. As these water droplets accumulate, they form condensate. Due to contamination by the corn, the color and smell of the condensate will change, which is called condensate wastewater. This condensate wastewater flows into the wastewater storage chamber 21 below through the drain hole 312 on the support layer 31, so that the water in the steamer 1 is not contaminated.

[0029] Example 2: This example provides a corn harvester, combined with... Figure 4-6 As shown, the difference from Embodiment 1 is that the steam channel 5 in this embodiment includes multiple steam outlets 231. A reinforcing plate 23 extending horizontally inward is provided around the top perimeter of the inner wall of the wastewater storage chamber 21 to enhance its structural strength. An appropriate distance is maintained between the reinforcing plate 23 and the supporting layer 31 of the steamer 3 so that steam can smoothly pass through the steam channel 5 into the steamer 3. Multiple upward-extending steam outlets 231 are provided on the reinforcing plate 23, and their positions are staggered with the steam through-holes 311 on the supporting layer 31. This design prevents condensate from flowing back into the steam channel 5 through the steam through-holes 311, ensuring that all condensate flows into the wastewater storage chamber 21.

[0030] Example 3: The difference from Example 1 is that in this example, two sewage collection boxes 2 and two steamers 3 are provided. One sewage collection box 2 is located between the two steamers 3 and is built on the lower steamer 3. The other sewage collection box 2 is built on the steamer 1.

[0031] Example 4: This example provides a corn harvester. The difference from Example 1 is that the sewage collection box 2 in this example only covers part of the steamer 1, and the steam channel 5 is formed by the sewage collection box 2 and the inner wall of the steamer 1.

[0032] In some embodiments, multiple wastewater collection boxes 2 may be set up separately on the steamer 1 or the steamer 3. For example, wastewater collection boxes 2 may be set up on two adjacent side walls of the steamer 1. Then the steam channel 5 is formed by the steamer 1 and the two wastewater collection boxes 2.

[0033] In some embodiments, sewage collection boxes 2 are respectively attached around the steamer 1, so the steam channel 5 is formed by multiple sewage collection boxes 2.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
