Description

Technical Field

[0001] This invention relates to the field of dried plum vegetable steaming technology, specifically to an auxiliary device for steaming dried plum vegetables. Background Technology

[0002] Dried plum vegetables are a traditional and affordable delicacy from Shaoxing, Zhejiang Province, and a famous local specialty. With a long history of production, they possess a unique aroma and delicious flavor, not only stimulating appetite but also offering nutritional benefits, making them a favorite among many diners.

[0003] Fresh mustard greens undergo multiple steaming and drying processes before becoming the uniquely flavored dish on our tables. Steaming large quantities of dried mustard greens requires frequent loading and unloading, affecting steaming efficiency. Furthermore, the steaming process generates a large amount of steam, which condenses at the top of the steamer, producing a significant amount of condensate. Additionally, the heat exchange between the steam and the dried mustard greens during steaming produces condensate, which flows to the lower layers due to gravity, affecting the steaming effect on the bottom layer. Moreover, steaming is the core process for making dried mustard greens; uneven heating during steaming can lead to inconsistent quality, impacting the final product's quality.

[0019] Beneficial effects

[0020] This invention provides an auxiliary device for steaming dried plum vegetables, which has the following beneficial effects:

[0021] 1. The device is equipped with a steam generating mechanism. The steam collecting pipe collects the steam from the top of the steamer and flows into the heat exchange tube through the return pipe. The heating tube heats the low-temperature steam inside the heat exchange tube. The heated steam is transported to the air inlet through a hose. The heated steam flows through the air outlet groove and air outlet to the bottom of the steamer. The rising steam steams the preserved vegetables on the top of the steamer. The steamed steam flows to the top of the steamer and is collected by the steam collecting pipe to form a cycle. By recovering and heating the steamed steam for recycling, energy consumption is reduced and the utilization rate of hot steam is improved.

[0022] 2. By setting up a steaming mechanism, the receiving plate and steamers are fixed to the outer wall of the steam supply mechanism. The steaming mechanism and dried plums can be directly placed in or removed by lifting the fixing slot. During steaming, the steam collection port gathers the new steam generated by the water tank and transmits the steam to the bottom of each layer of steamers through the steam outlet on the inner wall of the sleeve. The steam flows upward to steam each layer of dried plums. The diameter of the steam outlet gradually decreases as the height of the sleeve increases to balance the rapid rise of the hot airflow, which would cause a large amount of steam to accumulate at the top, thus reducing the steam flow of each layer of steamers. The distribution is uniform, and the condensate produced during the steaming of dried plum vegetables drips through the bottom of the steamer onto the upper surface of the receiving plate. When the steam rises, it passes through the venting mesh and blows the mesh upwards. The accumulated liquid is guided by the venting mesh into the water collection tank, then drains through the drain hole into the drain trough, and finally flows into the water collection tank along the drain trough. This prevents the condensate from accumulating downwards due to gravity, which would affect the steaming of the dried plum vegetables on the lower layer. It simplifies the preparation process before and after steaming, improves the uniformity of steaming, and avoids the impact of condensate on the steaming of dried plum vegetables.

[0023] 3. By setting up control components and a steaming mechanism, in the early stage of steaming, rotating the handle engages with the threaded hole, causing the adjusting rod to move the sealing plug away from the inner wall of the air collecting port and downwards. The new steam flowing into the sleeve from the lower end of the air collecting port and the hot steam flowing into the air inlet from the hose and then into the sleeve through the air outlet mix together to steam the preserved vegetables on the upper surface of each layer of steamers. In the later stage of steaming, rotating the handle in the opposite direction causes the adjusting rod to move the sealing plug upwards, sealing the lower end of the air collecting port. At the same time, the power of the heating tube is reduced, and only the steam recovered in the heat exchange tube is heated. The preserved vegetables are steamed using heated steam, which reduces the moisture content in the steam, reduces heating energy consumption, accelerates the steaming rate of the preserved vegetables, and reduces the moisture content of the finished preserved vegetables.

[0039] The following disclosure provides many different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention.

In addition, examples of various specific processes and materials are provided, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0040] This invention provides an auxiliary device for steaming dried plum vegetables, including a steam generating mechanism 1. A steamer 2 is fixedly connected to the upper end of the steam generating mechanism 1. A steaming mechanism 4 is installed inside the steamer 2. The steaming mechanism 4 delivers the steam generated by the steam generating mechanism 1 to the inner cavity of the steamer 2. A regulating component 3 is slidably connected to the upper end of the steaming mechanism 4. The upper end of the regulating component 3 extends through the top of the steamer 2 to the outside, and the lower end of the regulating component 3 extends through the steaming mechanism 4 into the inner cavity of the steam generating mechanism 1.

[0041] The steamer 2 includes a steamer body 22, and a steamer lid 21 is fixedly connected to the top of the steamer body 22. The steamer lid 21 includes a cover body 212, and a steam collecting pipe 213 is fixedly connected to the lower end face of the cover body 212. The steam collecting pipe 213 has a steam outlet 214 on its side wall.

[0042] The steam generating mechanism 1 includes a heating box 11, with heating pipes 17 installed on the inner wall of the heating box 11. A water tank 15 is installed at the bottom of the inner cavity of the heating box 11. A heat exchange pipe 14 is spirally arranged on the outer wall of the water tank 15 and is fixedly connected to the outer wall of the water tank 15. One end of the heat exchange pipe 14 is fixedly connected to a return pipe 16. The end of the return pipe 16 facing away from the heat exchange pipe 14 passes through the inner cavity of the steamer body 22 and is fixedly connected to the steam outlet 214. The other end of the heat exchange pipe 14 is fixedly connected to a flexible hose 13.

[0043] The control component 3 includes an adjustment rod 31, a sealing plug 35 is fixedly connected to the lower end of the adjustment rod 31, an air inlet channel 33 is opened at the end of the adjustment rod 31 connected to the sealing plug 35, and a number of air outlet grooves 34 are spaced apart on the outer wall of the adjustment rod 31. The air outlet grooves 34 are connected to the adjustment rod 31, and the hose 13 passes through the lower end face of the sealing plug 35 and is connected to the air inlet channel 33.

[0044] Please see 2 and Figure 4Heating tube 17 heats water tank 15 to generate new steam. The steam is transported to the inner cavity of steamer body 22 through steaming mechanism 4 to steam the preserved vegetables. The steam temperature decreases after steaming and gathers at the lower end of lid 21. It is collected through steam collection pipe 213 and flows through return pipe 16 to the inside of heat exchange tube 14. Heating tube 17 heats heat exchange tube 14, so that low-temperature steam becomes high-temperature steam after heat exchange. High-temperature steam is transported through hose 13 to air inlet 33, and then through air outlet 34 to the inside of steaming mechanism 4. It steams the preserved vegetables together with the new steam. While increasing the amount of steam, the moisture content of the steam is reduced, and the steaming rate is increased.

[0045] Specifically, the upper end of the water tank 15 is provided with a plug hole. The end of the flexible hose 13 facing away from the heat exchange tube 14 first passes through the plug hole and extends into the inner cavity of the water tank 15. Then it passes through the sealing plug 35 and is detachably sealed to the air inlet channel 33. The flexible hose 13 is a heat-resistant flexible hose, and the heat exchange tube 14 is a high thermal conductivity metal tube, such as a copper tube.

[0046] It should be added that the side wall of the main body 22 of the steamer is provided with a receiving groove, and the return pipe 16 is located in the receiving groove. The upper end of the return pipe 16 is provided with a funnel-shaped elastic interface. During steaming, the elastic interface is located inside the air outlet 214. When the steam flows, the interface opens and sticks to the side wall of the air collecting pipe 213 to seal the interface. When feeding, the steamer cover 21 is opened, and the elastic interface is pulled out from the air outlet 214 by external force.

[0047] It should also be noted that the inner diameter of the heating tube 17 is larger than the outer diameter of the heat exchange tube 14, and the inner diameter of the heat exchange tube 14 is larger than the outer diameter of the water tank 15.

[0048] In this embodiment, the steaming mechanism 4 includes a steam supply mechanism 41. Several sets of steamer baskets 43 are fixedly connected to the outer wall of the steam supply mechanism 41 at intervals. Each set of steamer baskets 43 has a receiving plate 42 at intervals at its lower end.

[0049] Please see Figure 5 The receiving plate 42 and the steamer 43 are both fixedly connected to the outer wall of the air supply mechanism 41. By lifting the upper end of the air supply mechanism 41, the steaming mechanism 4 and the dried plum vegetables can be lifted up, saving the operation time of loading and unloading the dried plum vegetables before and after steaming. During steaming, the condensate generated by the steamer 43 drips onto the upper surface of the receiving plate 42, avoiding affecting the steaming of the lower steamer 43.

[0050] Specifically, the outer diameters of the receiving plate 42 and the steamer 43 are equal and the same as the inner diameter of the steamer body 22. After the steaming mechanism 4 is installed, the outer walls of the air supply mechanism 41 and the receiving plate 42 are connected to the inner wall of the steamer body 22. The air supply mechanism 41 has an outer edge of a certain height to prevent the piled dried plum vegetables from falling off during loading and unloading.

[0051] In this embodiment, the gas supply mechanism 41 includes a sleeve 413, with a gas collecting port 415 fixedly connected to the lower end of the sleeve 413. The gas collecting port 415 is installed on the top of the steam port 12. A number of sets of gas outlet holes 414 are spaced apart on the outer wall of the sleeve 413, and the gas outlet holes 414 communicate with the inner cavity of the sleeve 413.

[0052] Please see Figure 6 Steam is collected through the air inlet 415, reaches the inner cavity of the sleeve 413, and is then blown to the lower end of the steamer 43 through the air outlet 414. The steam flows upward and steams the dried plums piled on the upper surface of the steamer 43. The air outlet 414 is spaced apart on the outer wall of the sleeve 413, and the outlet is located at the upper end of each set of receiving plates 42. At the same time, the opening diameter of the air outlet 414 gradually decreases vertically upward to prevent the steam from flowing quickly to the top, which would reduce the amount of steam in the lower layer and make the steam distribution of each layer uneven, thus improving the uniformity of the steam at the bottom of each layer of the steamer 43.

[0053] It should be noted that a fixing groove 411 is provided on the upper outer wall of the sleeve 413 to facilitate lifting the air supply mechanism 41, and an installation hole 412 is provided on the top of the sleeve 413, and the adjusting rod 31 is slidably connected inside the installation hole 412.

[0054] In this embodiment, the receiving plate 42 includes a water collection tank 421, an inner ring 422 and an outer ring 424. The inner ring 422 and the outer ring 424 are fixedly connected by several sets of water collection tanks 421. A breathable net 423 is fixedly connected at the gap between the several sets of water collection tanks 421. Several sets of drainage holes 425 are spaced apart on the outer wall of the outer ring 424.

[0055] Please see Figure 7 Steam flows upward through the lower end of the receiving plate 42. The airflow passes through the venting mesh 423 and inflates it. During steaming, the condensate produced by the steaming of the preserved vegetables on the upper surface of the steamer 43 drips onto the upper surface of the venting mesh 423. The inflated venting mesh 423 collects the droplets into the water collection tank 421, and then flows downward along the inner wall of the steamer body 22 through the drain hole 425. This avoids affecting the steam flow and prevents the condensate from affecting the steaming of the lower layer of preserved vegetables.

[0056] It should be noted that the water collection tank 421 consists of several sets of concentric circular water channels, which are connected by a cross-shaped water channel. The inner ring 422 and the outer ring 424 enclose the inner and outer walls of the water channel, forming a water storage channel together with the water collection tank 421. The bottom of the cross-shaped water channel gradually decreases from the center to the edge. The drain hole 425 is located in a position corresponding to the outlet of the cross-shaped water channel to facilitate the discharge of accumulated liquid. The breathable net 423 is a high-density net and its surface is coated with a hydrophobic material. While the gas flows through the breathable net 423, the liquid is prevented from seeping into the upper surface of the breathable net 423.

[0057] In this embodiment, a threaded hole 211 is provided on the lower end face of the cover 212, and a thread 32 is provided on the upper end of the adjusting rod 31. The adjusting rod 31 is threadedly connected to the threaded hole 211 through the thread 32.

[0058] Please see Figure 2 and Figure 3 The adjusting rod 31 has a handle at one end extending from the cover 212. The handle can be used to control the rotation of the adjusting rod 31. When the adjusting rod 31 rotates, the thread 32 engages with the threaded hole 211, causing the adjusting rod 31 to move the sealing plug 35 up and down. When the sealing plug 35 moves down, the lower channel of the gas collecting port 415 opens, and the steam generated by the water tank 15 enters the sleeve 413 through the gas collecting port 415, and then passes through the air outlet 414 to steam the dried plum vegetables. When the sealing plug 35 moves up, the lower channel of the gas collecting port 415 closes. At this time, the heating power of the heating tube 17 is reduced, and only the high-temperature steam output from the hose 13 is used to steam the dried plum vegetables. This reduces energy consumption and the moisture content in the steam, thereby reducing the moisture content of the finished dried plum vegetable product.

[0059] It should be noted that the outer diameter of the handle does not exceed the diameter of the adjusting rod 31.

[0060] In other embodiments, the steaming process can be carried out by heating with only reflux steam in the later stage. During the steaming process, the moisture in the steam condenses and the moisture in the reflux steam gradually decreases as the steam circulates. At this time, the heating power of the heating tube 17 can be controlled to air dry the preserved vegetables. Alternatively, the connection between the air collection port 415 and the water tank 15 can be controlled, and the preserved vegetables can be steamed, steamed at low humidity, and air dried in combination with the adjustment of the heating tube 17 to improve the flavor of the preserved vegetables.

[0061] In this embodiment, the main body 22 of the steamer includes a cage body 222. The inner wall of the cage body 222 is provided with a plurality of drainage grooves 221 spaced apart. The return pipe 16 passes through a set of drainage grooves 221 and is fixedly connected to the air supply hole 214. A water collection trough 224 is fixedly connected to the bottom of the cavity of the cage body 222. A drainage hole 223 is provided at the bottom of the water collection trough 224.

[0062] Please see Figure 10 The number of drainage troughs 221 is greater than that of drain holes 425. Some of the drainage troughs 221 are located corresponding to the drain holes 425, which can quickly guide the condensate discharged from the drain holes 425 into the water collection trough 224. The drain hole 223 is connected to the outside of the steamer body 22. When the liquid in the water collection trough 224 reaches a certain height, the drain hole 223 is opened to drain the liquid.

[0063] It should be noted that the drain hole 223 is opened at an angle downwards, and an observation window is provided at the bottom of the outer wall of the cage 222, which can be used to observe the liquid level in the water collection tank 224 in real time.

[0064] In this embodiment, the top of the water tank 15 is raised and a steam port 12 is opened at the center of the top. The outer diameter of the steam collection port 415 is larger than the inner diameter of the steam port 12, and the curvature of the inner wall of the steam collection port 415 is adapted to the top of the water tank 15.

[0065] Please see Figure 4 and Figure 6 The top of the water tank 15 protrudes upwards. During installation, the air collection port 415 is placed on top of the steam port 12. The inner wall of the air collection port 415 fits with the protrusion on the top of the water tank 15 to prevent the air collection port 415 from sliding on the upper surface of the water tank 15 and to provide support for the sleeve 413. The receiving plate 42 and the steamer 43 are fixed to the outer wall of the sleeve 413. Gravity causes the inner wall of the air collection port 415 to seal with the protrusion on the top of the water tank 15. After steaming, the steam supply mechanism 41 can be lifted directly upwards to remove the dried plum vegetables.

[0066] It should be noted that an elastic anti-slip pad is provided on the lower end face of the air collection port 415. The elastic anti-slip pad can be made of non-toxic, heat-resistant elastic materials such as TPE and silicone rubber.

[0067] It should also be noted that a pressure relief valve is installed on the top of the water tank 15, and an inlet / outlet valve is installed at the bottom of the water tank 15.

[0068] In this embodiment, the distance between two adjacent sets of steamer baskets 43 is 18-25 cm, and the distance between the steamer basket 43 and its lower end support plate 42 is 3-5 cm.

[0069] In this embodiment, the lower end of the adjusting rod 31 extends out of the bottom of the sleeve 413 and is fixedly connected to the sealing plug 35. The sealing plug 35 is a frustum, and the diameter of the upper frustum is less than the inner diameter of the sleeve 413 and less than the diameter of the lower frustum.

[0070] Please see Figure 8 The sealing plug 35 is located at the lower end outlet of the sleeve 413. When the adjusting rod 31 moves the sealing plug 35 upward, the upper end of the sealing plug 35 extends into the sleeve 413 and seals the lower end of the sleeve 413.

[0071] In summary, the present invention provides an auxiliary device for steaming preserved mustard greens. The preserved mustard greens to be steamed are placed on the upper surface of the steamer 43. The steam supply mechanism 41, with the receiving plate 42 and the steamer 43 installed, is placed inside the steamer body 22. At this time, the lower surface of the steam collection port 415 contacts the upper surface of the water tank 15. Under the action of the steaming mechanism 4 and the weight of the preserved mustard greens, the steam collection port 415 is compressed, sealing it with the top protrusion of the water tank 15, thus completing the feeding of the preserved mustard greens. The steamer lid 21 is installed on the top of the steamer body 22, and the adjusting rod 31 extends out of the top of the lid 21 through the threaded hole 211. When steaming begins, the heating tube 17 heats the heat exchange tube 14 and the water tank 15. The new steam generated by the water tank 15 passes through the steam port 12 and is collected by the steam collection port 415. Steam flows into the inner cavity of the sleeve 413, passes through the vent 414 to reach the lower end face of each layer of steamer 43, and flows upward to steam the preserved vegetables. After steaming, the temperature of the steam decreases, and the low-temperature steam is collected by the gas collecting pipe 213 and flows into the return pipe 16 through the gas delivery hole 214, and then flows back to the heat exchange pipe 14 for heat exchange. The heated steam flows from the hose 13 into the air inlet channel 33, passes through the air outlet groove 34 and flows into the inner cavity of the sleeve 413, where it mixes with the new steam to steam the preserved vegetables, thereby increasing the amount of steam during steaming and improving the steaming efficiency. During steaming, the condensate generated on the upper end face of the steamer 43 drips onto the upper end face of the receiving plate 42. The steam flow causes the vent mesh 423 to bulge, thereby collecting the condensate into the collection plate. The water in the tank 421 is then discharged into the drain tank 221 through the drain hole 425, where it collects with the condensate from the top and side walls into the water collection tank 224, and finally drains out through the drain hole 223. This prevents condensate from dripping onto the dried plum vegetables and affecting the steaming process. Later in the steaming process, rotating the handle thread 32 engages with the threaded hole 211, causing the adjusting rod 31 to move the sealing plug 35 upwards. The upper end of the sealing plug 35 is inserted into the lower channel of the air collection port 415, isolating the connection between the air collection port 415 and the steam port 12. Simultaneously, the heating power of the heating tube 17 is reduced, heating only the return steam inside the heat exchange tube 14. The heated return steam then passes through the air outlet 34 and the air outlet 414 to steam the dried plum vegetables, reducing heating energy consumption. This reduces the moisture content in the steam, thereby increasing the steaming rate of the dried plums and reducing the moisture content of the finished dried plums. A pressure relief valve is installed on the top of the water tank 15 to prevent heat accumulation in the water tank 15 when the heating tube 17 is heating, which could cause safety hazards. The connection and disconnection between the air collection port 415 and the water tank 15 can also be controlled multiple times to allow the dried plums to undergo steaming and low-humidity steaming, thereby improving the flavor of the dried plums. After steaming, the heating is turned off, the cage cover 21 is opened, and the steaming mechanism 4 and the dried plums can be completely removed by lifting the fixing groove 411. Then, another set of steaming mechanisms 4 that has been assembled is placed into the inner cavity of the steamer body 22 for the next batch of steaming. This avoids the potential hazards caused by contact with the high-temperature steamer when unloading, and at the same time improves the efficiency of loading and unloading.
