Description

Technical Field

[0001] This utility model relates to the field of popcorn equipment technology, specifically to an air puffing machine. Background Technology

[0002] Popcorn, a popular traditional snack, enjoys widespread market demand in cinemas, amusement parks, shopping malls, and many other places, and its market size continues to expand. Regarding the popcorn-making process, most popcorn machines on the market are based on the oil-popping principle. This traditional oil-popping method uses high-temperature oil to rapidly heat and expand the corn kernels, causing them to burst and form popcorn. However, oil-popped popcorn suffers from a significant problem of excessively high calorie content.

[0003] To meet people's pursuit of healthy food, air-pop popcorn machines have emerged. These machines use hot air as the heating medium, replacing traditional oil-based methods, significantly reducing the calories in popcorn and satisfying consumers' demand for healthy snacks. However, existing air-pop popcorn machines still have many shortcomings in terms of technological implementation.

[0004] Existing air-pop popcorn machines typically use a heating method where hot air is blown directly upwards into the popcorn pot. This method heats the kernels in the pot from only one fixed direction. Since the kernels are randomly distributed within the pot and constantly tumble and move during heating, this single heating direction results in significant differences in heating intensity across kernels at different locations. Kernels closer to the hot air inlet quickly receive enough heat to expand and pop, while kernels farther away may not expand sufficiently due to insufficient heating, or may burst into irregular shapes due to uneven heating. This uneven heating makes it difficult for existing air-pop popcorn machines to produce perfectly round popcorn. Round popcorn is not only more visually appealing but also has a more uniform and crispier texture, better meeting consumer aesthetic and taste preferences.

[0005] Given the problems with the existing technology, it is urgent to develop an air puffing machine that can pop corn kernels into spherical popcorn. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] This invention provides an air puffing machine, which can at least solve the technical problem of: how to improve the uniformity of heating so as to pop corn kernels into spherical popcorn.

[0008] (II) Technical Solution

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an air extruder, comprising:

[0010] The server rack contains an air intake duct, an expansion chamber, and an air exhaust duct. The lower side of the expansion chamber is connected to the air intake duct, and the upper side of the expansion chamber is connected to the air exhaust duct. The air intake duct, the expansion chamber, and the air exhaust duct together form a closed loop.

[0011] The circulating heating device is installed on the cabinet and located between the air inlet of the air inlet channel and the air outlet of the air outlet channel. The circulating heating device is used to heat the air in the cabinet and form hot air that circulates from the air inlet channel to the air outlet channel along the circulation loop.

[0012] The inner liner is located in the expansion chamber of the cabinet and includes an arc-shaped air inlet bottom shell. Multiple air guide holes are arranged in a ring at intervals on the air inlet bottom shell. The air guide holes are inclined and are used to guide hot air to flow into the inner liner at an angle, forming a spiral upward vortex of hot air in and above the inner liner.

[0013] Further, the aforementioned circulating heating device includes:

[0014] The hot air blower is mounted on the cabinet. The impeller of the hot air blower is located inside the air inlet of the air inlet channel and is connected to the air outlet of the air outlet channel.

[0015] The finned heater is located in the air outlet duct and is used to heat the hot air flowing through the air outlet duct.

[0016] Furthermore, at least two finned heaters are provided, with each finned heater being equally spaced along the conveying direction of the air outlet channel.

[0017] Furthermore, the aforementioned air inlet bottom shell is provided with at least two air guiding zones, which are arranged radially at intervals along the air inlet bottom shell. Each air guiding zone is composed of multiple annularly spaced air guiding holes.

[0018] Furthermore, the aforementioned inner liner also includes guide ribs, which are integrally connected to the outer surface of the air inlet bottom shell. The number of guide ribs is the same as the number of air guide holes, and their positions are set in a one-to-one correspondence. A guide channel is formed between the guide ribs and the air inlet bottom shell, which communicates with the corresponding air guide holes. The guide channel is set in the same direction of inclination as the air guide holes.

[0019] Furthermore, the aforementioned cabinet is also equipped with a slag discharge channel for connecting the puffing chamber to the outside of the cabinet. A baffle is provided at the inlet of the slag discharge channel. The baffle is located between the air inlet of the puffing chamber and the air outlet channel and is used to prevent popcorn or corn kernels in the puffing chamber from moving out of the puffing chamber. The baffle is provided with filter holes for corn residue to pass through. The slag discharge channel is used to guide the corn residue to move out of the cabinet.

[0020] Further configuration: the aforementioned baffle includes a first plate, a second plate, and a third plate connected in sequence. The first plate abuts against the side of the slag discharge channel facing the inner liner. Both the first and third plates extend towards the inner liner from bottom to top, with the slope of the third plate being less than that of the first plate. The third plate is positioned opposite the air inlet of the air outlet channel. The second plate is vertically positioned above the inner liner, with filter holes located on the second plate and extending to the third plate.

[0021] Furthermore, the aforementioned air extruder also includes:

[0022] The seasoning box is located on the outside of the cabinet. The bottom surface of the seasoning box extends upward at an angle. The higher side of the bottom of the seasoning box has a discharge port. The cabinet is also equipped with a seasoning conveying channel that extends downward at an angle. The higher end of the seasoning conveying channel is located below the discharge port, and the lower end of the seasoning conveying channel is located above the inner liner.

[0023] The mixing and conveying device is located on the cabinet and is used to mix the seasonings in the seasoning box and output the seasonings through the discharge port.

[0024] Further, the aforementioned mixing and conveying device includes a mixing rod, mixing blades, and a rotating mechanism. The rotating mechanism is mounted on a cabinet. One end of the mixing rod is inserted into the seasoning box, and the other end passes through the discharge port and is connected to the output end of the rotating mechanism. The mixing blades are spirally arranged around the axial direction of the mixing rod on the outer peripheral wall of the mixing rod and are in contact with the bottom surface of the seasoning box. The rotating mechanism is used to drive the mixing rod and mixing blades to rotate, so as to mix the seasonings at the bottom of the seasoning box and output the seasonings to the discharge port.

[0025] (III) Beneficial Effects

[0026] Compared with the prior art, the air extruder provided by this utility model has the following beneficial effects:

[0027] The air popper provided by this utility model first pours corn kernels into the inner chamber; then, the circulating heating device is activated, generating a stream of hot air that circulates along the loop. This hot air flows obliquely upwards into the inner chamber from the air guide holes, forming a vortex of hot air rotating within and above the inner chamber. This ensures more even heating of the corn kernels, causing them to pop into spherical popcorn. It can be seen that this utility model, through its arc-shaped air inlet shell and obliquely arranged air guide holes, can create a spiraling upward vortex of hot air within the inner chamber, ensuring that the corn kernels in the popping chamber are heated evenly, thus helping to pop the kernels into spherical shapes and improving the quality of the popcorn. Furthermore, this utility model, by constructing a closed circulation loop, achieves the recycling of hot air, improving energy efficiency. Attached Figure Description

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] This invention provides an air puffing machine to solve the problem of how to improve heating uniformity in order to pop corn kernels into spherical popcorn.

[0041] See Figure 1 , Figure 2 and Figure 3 As shown, Figure 1 This is a perspective view of the air extruder in the embodiment. Figure 2 This is a cross-sectional view of the internal structure of the air extruder in the embodiment. Figure 3 for Figure 2An enlarged schematic diagram at point A shows that the air extruder includes a cabinet 1, a circulating heating device 2, and an inner liner 3.

[0042] The cabinet 1 is equipped with an air inlet channel 11, an expansion chamber 12, and an air outlet channel 13. The lower side of the expansion chamber 12 is connected to the air inlet channel 11, and the upper side of the expansion chamber 12 is connected to the air outlet channel 13. The air inlet channel 11, the expansion chamber 12, and the air outlet channel 13 together form a closed loop.

[0043] The circulating heating device 2 is installed on the cabinet 1 and is located between the air inlet of the air inlet channel 11 and the air outlet of the air outlet channel 13. The circulating heating device 2 is used to heat the air inside the cabinet 1 and form hot air that circulates along the circulation loop from the air inlet channel 11 toward the air outlet channel 13.

[0044] The inner liner 3 is installed inside the expansion chamber 12 of the cabinet 1. The inner liner 3 includes an arc-shaped air inlet bottom shell 31, on which multiple air guide holes 3111 are distributed in a ring at intervals. The air guide holes 3111 are inclined and are used to guide hot air to flow into the inner liner 3 at an angle, forming a spiral upward vortex of hot air in and above the inner liner 3.

[0045] When using the air-expanding machine described above, firstly, corn kernels are poured into the inner chamber 3; then, the circulating heating device 2 is activated. The circulating heating device 2 generates a stream of hot air that circulates along the loop. The hot air flows obliquely upwards into the inner chamber 3 through the air guide holes 3111, forming a vortex of hot air rotating within and above the inner chamber 3. This ensures that the corn kernels are heated more evenly, causing them to pop into spherical popcorn. It can be seen that this invention, through its arc-shaped air inlet shell 31 and the obliquely arranged air guide holes 3111, can form a spiraling upward vortex of hot air within the inner chamber 3, ensuring that the corn kernels in the puffing chamber 12 are heated evenly, thus helping to pop the kernels into spherical shapes and improving the quality of the popcorn. Furthermore, this invention, by constructing a closed loop, achieves the recycling of hot air, improving energy efficiency.

[0046] See Figure 1 and Figure 2As shown, in one embodiment of the circulating heating device 2, the circulating heating device 2 includes a hot air blower 21 and a finned heater 22. The hot air blower 21 is installed on the cabinet 1, and the impeller 211 of the hot air blower 21 is located in the air inlet of the air inlet channel 11 and communicates with the air outlet of the air outlet channel 13. The finned heater 22 is installed in the air outlet channel 13 by means of screwing or welding, and is used to heat the hot air flowing through the air outlet channel 13. In this way, when the hot air blower 21 is started, it can heat the air in the cabinet 1 and promote the circulation of hot air, providing a heat source for the puffing of corn kernels and playing the role of recycling hot air. However, since a large amount of heat is lost with each flow of hot air, especially after the corn kernels are popped, the finned heater 22 can further heat the hot air to replenish the heat lost by the hot air, thereby ensuring the stability of the heat source provided for the puffing of corn kernels and ensuring the smooth progress of the puffing process.

[0047] The hot air blower 21 and finned heater 22 mentioned above can be any existing brand of hot air blower 21 and finned heater 22.

[0048] See Figure 2 As shown, based on the above embodiment, at least two finned heaters 22 are provided, and each finned heater 22 is equally spaced along the conveying direction of the air outlet channel 13. This increases the contact area between the hot air and the finned heaters 22, improves heating efficiency, and allows the hot air to reach the appropriate temperature more quickly, thereby shortening the expansion time and improving production efficiency.

[0049] See Figure 3 As shown, based on any of the above embodiments, the air inlet bottom shell 31 has at least two air guiding zones 311, which are radially spaced along the air inlet bottom shell 31. Each air guiding zone 311 is composed of multiple annularly spaced air guiding holes 3111. This further optimizes the distribution of hot air, allowing it to enter the puffing chamber 12 more evenly, ensuring that the corn kernels are heated more uniformly at all locations, thereby further improving the quality of the popcorn.

[0050] The number of air guide holes 3111 in the different air guide zones 311 mentioned above can be the same, or the number can gradually increase from the inside to the outside along the radial direction. The latter can heat the corn kernels more evenly.

[0051] See Figure 3As shown, based on the above embodiment, the inner liner 3 also includes guide ribs 32. The guide ribs 32 are integrally connected to the outer surface of the air inlet bottom shell 31. The number of guide ribs 32 is the same as the number of air guide holes 3111, and their positions correspond one-to-one. A guide channel 33 is formed between the guide ribs 32 and the air inlet bottom shell 31, communicating with the corresponding air guide hole 3111. The guide channel 33 is inclined in the same direction as the air guide hole 3111. Thus, the guide channel 33 can greatly extend the air guide hole 3111, further guiding the flow direction of hot air, enhancing the effect of vortex hot air, allowing the corn kernels to tumble and be heated more fully in the puffing chamber 12, thereby further improving the popping effect and quality of the popcorn.

[0052] The optimal tilt angle range for the aforementioned air guide hole 3111 is 40°-50°.

[0053] See Figure 1 and Figure 4 As shown, Figure 4 The diagram shows a partial cross-sectional view of the cabinet, inner liner, and baffle in one embodiment. Based on any of the above embodiments, the cabinet 1 also includes a slag discharge channel 14 connecting the puffing chamber 12 to the outside of the cabinet 1. A baffle 4 is installed at the inlet of the slag discharge channel 14, located between the puffing chamber 12 and the air inlet of the air outlet channel 13. The baffle 4 prevents popcorn or corn kernels inside the puffing chamber 12 from leaving the chamber. The baffle 4 has filter holes 41 for corn residue to pass through. The slag discharge channel 14 guides the corn residue out of the cabinet 1. Thus, during the popcorn popping process, because the corn residue and some popcorn in the puffing chamber 12 are relatively light, they may be moved from the puffing chamber 12 into the air outlet 13 with the hot air. However, since the baffle 4 is located between the air inlet of the puffing chamber 12 and the air outlet 13, the hot air in the puffing chamber 12 needs to pass through the filter hole 41 to enter the air outlet 13. The popcorn is much larger than the filter hole 41 and cannot pass through the filter hole 41 with the hot air. The corn residue can pass through the filter hole 41 with the hot air, but since the air force is greatly reduced by the baffle 4 after the hot air passes through the filter hole 41, it cannot carry the corn residue into the air outlet 13. Therefore, after the corn residue passes through the filter hole 41, it will fall freely into the slag discharge channel 14 and be moved out of the cabinet 1 along the slag discharge channel 14. As can be seen, this utility model can effectively prevent popcorn or corn kernels from moving out of the puffing chamber 12 with the hot air through the baffle 4. Combined with the slag discharge channel 14, it can also play the role of automatic slag filtering and slag discharge. This not only effectively prevents corn slag and popcorn in the puffing chamber 12 from moving into the air outlet channel 13 with the hot air and affecting the operation of the circulating heating device 2, but also keeps the puffing chamber 12 clean and avoids the impact of residue on the quality of popcorn.

[0054] See Figure 2 and Figure 4As shown, in one embodiment of the baffle 4, the baffle 4 includes a first plate 42, a second plate 43, and a third plate 44 connected in sequence. The first plate 42 abuts against the side of the slag discharge channel 14 facing the inner liner 3. Both the first plate 42 and the third plate 44 are inclined upwards towards the inner liner 3, with the inclination of the third plate 44 being less than that of the first plate 42. The third plate 44 is positioned opposite the air inlet of the air outlet channel 13. The second plate 43 is vertically arranged and located above the inner liner 3. Filter holes 41 are opened on the second plate 43 and extend to the third plate 44. Thus, the baffle 4, through the first plate 42, can prevent most of the corn kernels and popcorn from moving out of the puffing chamber 12 with the hot air, and through the second plate 43 and the third plate 44, can further prevent the corn kernels and popcorn from moving out of the puffing chamber 12 with the hot air, improving the blocking effect and also weakening the force of the hot air, ensuring that the hot air cannot carry the corn residue into the air outlet channel 13 after passing through the filter holes 41.

[0055] See Figure 1 and Figure 2 As shown, based on any of the above embodiments, the air puffing machine also includes a seasoning box 5 and a stirring and conveying device 6. The seasoning box 5 is installed on the outside of the cabinet 1 by means of screwing or hanging, and the bottom surface of the seasoning box 5 extends upward at an angle. A discharge port 51 is opened on the higher side of the bottom of the seasoning box 5. The cabinet 1 also has a seasoning conveying channel 15 extending downward at an angle. The higher end of the seasoning conveying channel 15 is located below the discharge port 51, and the lower end of the seasoning conveying channel 15 is located above the inner liner 3. The stirring and conveying device 6 is installed on the cabinet 1. The stirring and conveying device 6 is used to stir the seasonings in the seasoning box 5 and output the seasonings to the discharge port 51. Thus, the seasoning box 5 is located outside the cabinet 1, making it convenient to add seasonings; when making popcorn, the stirring and conveying device 6 outputs the seasonings from the outlet 51, and the seasonings can fall smoothly into the seasoning conveying channel 15 by gravity, and then be smoothly conveyed to the top of the inner liner 3 along the seasoning conveying channel 15, thereby realizing the automatic conveying of seasonings and improving the efficiency and uniformity of seasoning addition.

[0056] The seasoning box 5 mentioned above can be used to hold syrup or other flavoring ingredients (such as honey, chocolate liquid, etc.) to give popcorn a rich flavor.

[0057] See Figure 1 and Figure 2As shown, in one embodiment of the mixing and conveying device 6, the mixing and conveying device 6 includes a mixing rod 61, mixing blades 62, and a rotating mechanism 63. The rotating mechanism 63 is mounted on the cabinet 1 by means of screwing or welding. One end of the mixing rod 61 is inserted into the seasoning box 5, and the other end passes through the discharge port 51 and is connected to the output end of the rotating mechanism 63 by means of screwing or welding. The mixing blades 62 are set on the outer peripheral wall of the mixing rod 61 by means of welding or integral connection. The mixing blades 62 are spirally distributed around the axial direction of the mixing rod 61 and are in contact with the bottom surface of the seasoning box 5. The rotating mechanism 63 is used to drive the mixing rod 61 and the mixing blades 62 to rotate, so as to mix the seasonings at the bottom of the seasoning box 5 and output the seasonings to the discharge port 51. Thus, when the rotating mechanism 63 is activated, it drives the stirring rod 61 and stirring blade 62 to rotate, thoroughly stirring the seasonings at the bottom of the seasoning box 5, ensuring the seasonings are evenly mixed so that they can be coated onto popcorn later. Simultaneously, the spiral structure of the stirring blade 62 drives the seasoning output outlet 51, preventing seasonings from accumulating at the bottom of the box and ensuring that all seasonings are output to the outlet 51, thus improving the utilization rate of the seasonings. It can be seen that the stirring and conveying device 6 provided in this embodiment only requires one drive to perform both stirring and conveying functions, greatly saving drive costs.

[0058] The aforementioned rotating mechanism 63 can use existing rotary motors or other rotary drive mechanisms.
