Description

Technical Field

[0001] The present invention belongs to the technical field of atomization devices, and particularly relates to an atomization device and a trichosanthes stir-frying machine or fermentation tower containing the atomization device. Background Art

[0002] Trichosanthes kirilowii Maxim., also known as medicinal melon, has the scientific name Trichosanthes kirilowii Maxim. It is a treasure all over. The melon shell can be used as medicine. After the mature trichosanthes seeds are dried, they can be used as health care and leisure foods. The root of trichosanthes can be made into trichosanthes root powder, with great utilization value and high economic benefits.

[0003] In the field of deep processing of trichosanthes kirilowii maxim., whether it is stir-frying trichosanthes seeds into dry trichosanthes seeds (a kind of leisure food) or fermenting trichosanthes leaves, roots, pulp, skins, etc. into by-products such as trichosanthes tea or trichosanthes wine, an atomization device is usually used. For example, in a stir-frying machine, it is necessary to evenly spray the seasoning soup into the stir-frying machine; in a fermentation tower, it is necessary to evenly spray the fermentation bacterial liquid. Currently, an atomizing nozzle is usually used to achieve the purpose of uniform spraying. However, it is found in practice that the atomizing nozzle only has a good atomization effect on liquids. Generally, the seasoning soup contains a large amount of insoluble substances such as spice powder that cannot be dissolved in water and the content is not low, and the microbial inoculum in the fermentation bacterial liquid is also insoluble in water, which results in that the outlet of the atomizing nozzle cannot be designed too large. The outlet diameter of the atomizing nozzle is an important parameter affecting the atomization quality. When the outlet diameter is 2.0 mm, the atomization effect is the best, the formed droplet size is the smallest and the distribution is uniform, showing a normal distribution, because it only depends on the water pressure and the atomization space (referring to the area where tiny water droplets are distributed formed by the fine water mist injection) is limited; as the outlet diameter increases to more than 3.0 mm, the droplet size gradually increases, the atomization effect decreases, and the atomization space decreases instead.

[0004] Therefore, generally in a stir-frying machine or a fermentation tower, multiple atomizing nozzles are usually arranged and are vertically downward. For example, for a trichosanthes stir-frying machine, the distribution density of the atomizing nozzles inside is generally 6 - 8 per m 3 (6 - 8 atomizing nozzles are arranged in each cubic meter of space). However, too many atomizing nozzles mean a greater risk of blockage, so frequent maintenance is required.

[0005] Based on this, the present invention is proposed. Summary of the Invention

[0006] The purpose of the present invention is to provide an atomization device and a trichosanthes stir-frying machine or fermentation tower containing the atomization device to solve the above problems.

[0007] In a first aspect, an atomizing device includes a liquid inlet pipe and a diffuser pipe. A plurality of feed pipes are arranged outside the liquid inlet pipe. A high-frequency vibration pipe assembly is arranged between the liquid inlet pipe and the diffuser pipe. The high-frequency vibration pipe assembly includes a core pipe member and a sleeve arranged outside the core pipe member. The liquid inlet pipe and all the feed pipes are communicated with the core pipe member. The diffuser pipe is communicated with the core pipe member. A hourglass-shaped flow blocking hole is arranged at the communicating part between the diffuser pipe and the core pipe member. The core pipe member successively includes a first straight pipe part, a second straight pipe part, and a third straight pipe part according to the flow direction. A flexible pipe section is connected between the second straight pipe part and the first straight pipe part and between the third straight pipe part and the second straight pipe part. An ultrasonic transducer one is sleeved outside the first straight pipe part, a megasonic transducer is sleeved outside the second straight pipe part, and an ultrasonic transducer two is sleeved outside the third straight pipe part. A non-Newtonian fluid medium is filled between the sleeve and the core pipe member. The liquid inlet pipe is externally connected with a variable-frequency pump.

[0008] For a further improvement, an inner conical nozzle is arranged at the liquid outlet end of the liquid inlet pipe. An outer conical nozzle is coaxially connected outside the inner conical nozzle. A first connecting disc is arranged between the liquid inlet pipe and the high-frequency vibration pipe assembly. A confluence hole is arranged at the center of the first connecting disc. The outer conical nozzle and the output ends of all the feed pipes are communicated with the confluence hole. The first straight pipe part and the sleeve are both fixedly connected with the first connecting disc.

[0009] For a further improvement, the small end of the outer conical nozzle is arranged inside the large end of the confluence hole. The small end of the confluence hole is communicated with the core pipe member. The small end of the inner conical nozzle is arranged inside the outer conical nozzle. The output ends of the feed pipes are all located outside the outer conical nozzle.

[0010] For a further improvement, a second connecting disc is connected between the diffuser pipe and the third straight pipe part. The flow blocking hole is arranged at the center of the second connecting disc. The diffuser pipe and the third straight pipe part are communicated through the flow blocking hole. The third straight pipe part and the sleeve are both fixedly connected with the second connecting disc.

[0011] For a further improvement, the working frequency of the ultrasonic transducer one is f1, with the unit kHz; the working frequency of the megasonic transducer is f2, with the unit kHz; the working frequency of the ultrasonic transducer two is f3, with the unit kHz; 20 ≤ f1 < f3 ≤ 35, 1000 ≤ f2 ≤ 2000.

[0012] For a further improvement, the inner diameters of the first straight pipe part, the second straight pipe part, and the third straight pipe part are all equal. The ratio of the inner diameter of the third straight pipe part to the minimum value of the aperture of the flow blocking hole is x, 10 ≤ x ≤ 20.

[0013] For a further improvement, the lengths of the first straight pipe part and the third straight pipe part are equal. The ratio of the length of the second straight pipe part to the length of the third straight pipe part is y, 1.1 ≤ y ≤ 1.5.

[0014] For further improvement, a water pipe is also provided between the second connecting disk and the first connecting disk. The water pipe is sleeved outside the sleeve. A heat exchange cavity is formed by the second connecting disk, the first connecting disk, the water pipe and the sleeve. The second connecting disk is provided with a water outlet pipe communicating with the heat exchange cavity, and the first connecting disk is provided with a water inlet pipe communicating with the heat exchange cavity.

[0015] Secondly, the atomization device of the present invention can be applied to a trichosanthes stir-frying machine.

[0016] Thirdly, the atomization device of the present invention can also be applied to a fermentation tower.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. For the atomization device of the present invention, through the optimized design of the structure of the existing atomizer, a liquid containing a large amount of powder can be rapidly atomized. The minimum outlet diameter (the aperture of the choke hole 61) is 6 mm, and it is not easy to be blocked. Even if a blockage occurs by chance, the variable-frequency pump cooperates with the coupled vibration of ultrasonic and megasonic waves, and can also dredge the powder blocked at the choke hole to avoid large-scale blockage. Even when the solid content of the liquid containing a large amount of powder reaches 30%, the atomization can still be kept uniform, which is especially suitable for application to a trichosanthes stir-frying machine, so as to meet the frying of trichosanthes seeds with different flavors.

[0019] 2. For the defects of the reduced atomization effect and uneven atomization caused by the increase of the outlet diameter; in the present invention, through the additional power provided by the variable-frequency pump cooperating with the coupled vibration of ultrasonic and megasonic waves, the defects of the reduced atomization effect and uneven atomization caused by the increase of the outlet diameter can be solved.

[0020] 3. The atomization device of the present invention can also be applied to a fermentation tower, with wide applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Embodiment 1

[0035] Such as Figure 1 、 2As shown, the atomization device includes a liquid inlet pipe 70 and a diffusion pipe 62. A plurality of feed pipes 40 are arranged outside the liquid inlet pipe 70. A high-frequency vibration pipe assembly is arranged between the liquid inlet pipe 70 and the diffusion pipe 62. The high-frequency vibration pipe assembly includes a core pipe part and a sleeve 28 sleeved outside the core pipe part. The liquid inlet pipe 70 and all the feed pipes 40 are communicated with the core pipe part. The diffusion pipe 62 is communicated with the core pipe part. A constriction hole 61 in the shape of an hourglass is arranged at the communication part between the diffusion pipe 62 and the core pipe part. The core pipe part sequentially includes a first straight pipe part 21, a second straight pipe part 22, and a third straight pipe part 23 according to the flow direction. A hose section 24 is connected between the second straight pipe part 22 and the first straight pipe part 21 and between the third straight pipe part 23 and the second straight pipe part 22. An ultrasonic transducer 31 is sleeved outside the first straight pipe part 21, a megasonic transducer 32 is sleeved outside the second straight pipe part 22, and an ultrasonic transducer 33 is sleeved outside the third straight pipe part 23. A non-Newtonian fluid medium 25 is filled between the sleeve 28 and the core pipe part. The liquid inlet pipe is externally connected with a variable-frequency pump.

[0036] In the present invention, taking this embodiment as an example, the atomization device is installed inside the trichosanthes fruit frying machine, and the trichosanthes fruit frying machine is as Figure 3 shown. The liquid inlet pipe 70 is used to convey the liquid material. To ensure uniform dispersion, two feed pipes 40 are provided. The feed pipes 40 are used to convey the thick soup containing powder. Finally, the thick soup and the liquid material with different components are mixed into a seasoning soup material inside the core pipe part. The liquid material is rapidly mixed under the ultrasonic and megasonic waves generated by the ultrasonic transducer 31, the megasonic transducer 32, and the ultrasonic transducer 33. After passing through the hourglass-shaped constriction hole 61, it is finally atomized and diffused at the diffusion pipe 62.

[0037] The atomization device of the present invention can be vertically arranged in the trichosanthes fruit frying machine or horizontally arranged in the trichosanthes fruit frying machine. Inside the trichosanthes fruit frying machine, it is preferably horizontally arranged because after the coupled vibration of ultrasonic and megasonic waves is applied, the spraying distance after atomization is farther. For a trichosanthes fruit frying machine with an internal space of 1.23 m 3 , only two atomization devices of the present invention need to be arranged (they can be arranged oppositely), and the distribution density of the atomization nozzles is 1.62 per m 3 , which is much smaller than the prior art (6 - 8 per m 3 ). Moreover, the minimum value of the aperture of the constriction hole 61 of the present invention is 6 mm. On the one hand, the minimum value of the aperture of the constriction hole 61 is much larger than the outlet diameter of the existing atomization nozzles, and it is not easy to be blocked. Even if it is blocked by chance, due to the drive of the variable-frequency pump, the flow rate or hydraulic pressure inside the core pipe part is constantly changing. Coupled with the coupled vibration of ultrasonic and megasonic waves, the powder blocked at the constriction hole 61 can also be dredged to avoid large-scale blockage.

[0038] Through a large number of experiments, it is found that: the operating frequency of the first ultrasonic transducer 31 is f1, with the unit of kHz; the operating frequency of the megasonic transducer 32 is f2, with the unit of kHz; the operating frequency of the second ultrasonic transducer 33 is f3, with the unit of kHz; 20 ≤ f1 < f3 ≤ 35, 1000 ≤ f2 ≤ 2000. For example, the operating frequency of the first ultrasonic transducer 31 is 20 - 26 kHz; the operating frequency of the megasonic transducer 32 is 1300 - 1901 kHz; the operating frequency of the second ultrasonic transducer 33 is 30 - 35 kHz; more specifically, for example, the operating frequency of the first ultrasonic transducer 31 is 20 kHz, the operating frequency of the megasonic transducer 32 is 1625 kHz, and the operating frequency of the second ultrasonic transducer 33 is 35 kHz.

[0039] The inner diameters of the first straight pipe section 21, the second straight pipe section 22, and the third straight pipe section 23 are equal. The ratio of the inner diameter of the third straight pipe section 23 to the minimum aperture diameter of the flow blocking hole 61 is x, where 10 ≤ x ≤ 20; x is preferably 13. The setting of x is mainly to ensure a sufficiently large expansion ratio, so that it can be better applied to the horizontal setting.

[0040] The lengths of the first straight pipe section 21 and the third straight pipe section 23 are equal. The ratio of the length of the second straight pipe section 22 to the length of the third straight pipe section 23 is y, where 1.1 ≤ y ≤ 1.5; y is preferably 1.4. The length of the second straight pipe section 22 needs to be long enough to ensure sufficient megasonic vibration.

[0041] If the first straight pipe section 21, the second straight pipe section 22, and the third straight pipe section 23 are an integral straight pipe, the coupling vibration effect of ultrasonic and megasonic waves will become worse. By setting the flexible pipe section 24, the vibration field strength in the areas where the first straight pipe section 21, the second straight pipe section 22, and the third straight pipe section 23 are located becomes more concentrated; for example, most of the middle parts of the first straight pipe section 21 and the third straight pipe section 23 are ultrasonic vibrations, most of the middle part of the second straight pipe section 22 is ultrasonic vibration, and at the joints between the first straight pipe section 21 and the second straight pipe section 22, and between the second straight pipe section 22 and the third straight pipe section 23, there is more coupling vibration.

[0042] The non - Newtonian fluid medium 25 is made by mixing corn starch and water in a mass ratio of 2.7:1. It has the property of shear thickening. Under high - frequency vibration in a specific range, it will gradually harden and become "semi - solidified". Under the restraint of the sleeve 28, it will promote the coupling of ultrasonic and megasonic waves at the joints between the first straight pipe section 21 and the second straight pipe section 22, and between the second straight pipe section 22 and the third straight pipe section 23.

[0043] Example 2

[0044] The liquid outlet end of the liquid inlet pipe 70 is provided with a conical inner nozzle 71 in a conical tube shape. An outer nozzle 72 in a conical tube shape that is coaxially connected to the outside of the inner nozzle 71 and communicates with the inner nozzle 71 is provided. A first connecting disc 50 is provided between the liquid inlet pipe 70 and the high-frequency vibration tube assembly. A concentric reducing orifice 51 in a reducing head shape is provided at the center of the first connecting disc 50. The outer nozzle 72 and the output ends of all the feed pipes 40 are all communicated with the reducing orifice 51. The first straight pipe portion 21 and the sleeve 28 are both fixedly connected to the first connecting disc 50. The liquid inlet pipe 70 is also externally connected with a connecting pipe 73 for connecting to a variable-frequency pump, and the connecting pipe 73 can be a flexible pipe.

[0045] Concentric reducing head: A type of pipe fitting with a diameter change, where the center lines at both ends coincide, used to connect two pipes with different diameters.

[0046] For a conical tube or a similar structure, the small end refers to the end with the smallest inner diameter, and the large end refers to the end with the largest inner diameter.

[0047] The liquid material sprayed from the liquid outlet end of the liquid inlet pipe 70 optimizes the pressure distribution through the outer nozzle 72, thereby improving the collision and mixing effects at the reducing orifice 51.

[0048] In addition, to further improve the mixing effect, the small end of the outer nozzle 72 is arranged inside the large end of the reducing orifice 51, and the small end of the reducing orifice 51 is communicated with the core pipe fitting. The small end of the inner nozzle 71 is arranged inside the outer nozzle 72, and the output ends of the feed pipes 40 are all located outside the outer nozzle 72.

[0049] Example 3

[0050] To facilitate the installation of the diffuser tube 62, a second connecting disc 60 is connected between the diffuser tube 62 and the third straight pipe portion 23. The flow blocking orifice 61 is provided at the center of the second connecting disc 60. The diffuser tube 62 and the third straight pipe portion 23 are communicated through the flow blocking orifice 61. The third straight pipe portion 23 and the sleeve 28 are both fixedly connected to the second connecting disc 60.

[0051] Example 4

[0052] For the Trichosanthes kirilowii stir-frying machine, the internal temperature is relatively high. To prevent the non-Newtonian fluid medium 25 composed of starch and water from gelatinizing, a water pipe 26 is further provided between the second connecting disc 60 and the first connecting disc 50. The water pipe 26 is sleeved outside the sleeve 28. The second connecting disc 60, the first connecting disc 50, the water pipe 26 and the sleeve 28 enclose a heat exchange cavity 27. The second connecting disc 60 is provided with a water outlet pipe 63 communicated with the heat exchange cavity 27, and the first connecting disc 50 is provided with a water inlet pipe 52 communicated with the heat exchange cavity 27.

[0053] The water inlet pipe 52 is connected to cooling water, and the cooling water enters the heat exchange chamber 27 to form a heat insulation layer, preventing the non-Newtonian fluid medium 25 in the sleeve 28 from gelatinizing due to excessive temperature.

[0054] If the atomizing device is used for a fermentation tower, it may not need to be provided with the heat insulation technology of this embodiment.

[0055] 1. Atomization uniformity test

[0056] For stir-fried trichosanthis seeds, since the seasoning soup contains a large amount of salt, sugar, spice powder, etc., therefore, a certain component attached to the surface of the trichosanthis seeds can be measured, for example, the sodium chloride content attached to the surface of the trichosanthis seeds can be measured by colorimetry, and then the mean value and variance are used to determine whether the purpose of uniform spraying is achieved.

[0057] In the prior art, a trichosanthis seed stir-frying machine with an internal space of 1.23 m 3 is internally provided with 8 atomizing nozzles (the outlet diameter of the atomizing nozzle is 2.0 mm). The final measurement result is that the mean sodium content of every 20 g of trichosanthis seeds is 663 mg, and the variance is 5924; according to the analysis of a large amount of data, when the mean sodium content is 660 ± 50 mg and the variance value is less than 7000, after tasting by tasters, it is found that there is no trichosanthis seed with a light or salty taste, and the taste is moderate.

[0058] 2. Blockage resistance test

[0059] Continuously atomize and spray for 35 min, and observe whether blockage occurs (there is an obvious lack of conical mist or no mist is ejected).

[0060] In Example 1, when the composition of the used seasoning soup changes, the test results are shown in Table 1:

[0061] Table 1

[0062] Average sodium content / mg Variance Clogging situation Group 1 652 5145 No clogging occurred Group 2 618 6833 No clogging occurred Group 3 / / Clogging occurred Group 4 / / Clogging occurred

[0063] In Table 1, in the seasoning soup used in Group 1, the sodium chloride content is 0.9%, and the solid content is 9.3%. In the seasoning soup used in Group 2, the sodium chloride content is 0.9%, the solid content is 30%, and the water-soluble red pigment content is 0.1%; if the existing atomizing nozzles (the outlet diameter of the atomizing nozzle is 2.0 mm) are used for the seasoning soup used in Group 2, blockage will definitely occur. In the seasoning soup used in Group 3, the sodium chloride content is 0.9%, the solid content is 21%, the tomato paste addition amount accounts for 12% of the seasoning soup, and the water-soluble red pigment content is 0.1%. In the seasoning soup used in Group 4, the sodium chloride content is 0.9%, the solid content is 18%, the hydrolyzed pectin addition amount accounts for 11% of the seasoning soup, and the water-soluble red pigment content is 0.1%.

[0064] As can be seen from Table 1, the atomization device of the present invention has good atomization effect; in the same space, even if the distribution density of the atomization device is much smaller than that of the existing atomization nozzles, the same atomization effect can be achieved. Even when atomizing a liquid containing powder, it is not easy to clog; even when the solid content in the liquid containing powder is as high as 30%, it will not get clogged; however, for liquids added with pastes such as tomato paste, or liquids added with hydrolyzed pectin (which may combine with metal ions such as calcium ions to form gels), its anti-clogging effect is average.

[0065] Comparative Example 1

[0066] In this example, compared with Example 1, an ordinary fixed-frequency pump was used to replace the variable-frequency pump, and the rest were the same.

[0067] During the test process of this example, it was found that when the solid content in the test seasoning soup was less than 3%, the test results of "the average sodium content is 660 ± 50 mg and the variance value is less than 7000" were satisfied, and no clogging occurred; but when the solid content in the test seasoning soup was equal to 12%, clogging occurred. While in Example 1, even when the solid content in the test seasoning soup was equal to 30%, no clogging occurred. This shows that relying solely on the ultrasonic vibration, megasonic vibration, and the coupled vibration of ultrasonic and megasonic in the high-frequency vibration tube assembly, it is impossible to ensure no clogging in the case of containing a large amount of spice powder.

[0068] Comparative Example 2

[0069] In this example, compared with Example 1, water was used to replace the non-Newtonian fluid medium 25, and the rest were the same.

[0070] During the test process of this example, it was found that in the test seasoning soup used, the sodium chloride content was 0.9%, the solid content was 30%, and the water-soluble red pigment content was 0.1%; no clogging occurred. However, the average sodium content was 597 mg and the variance value was 230604, indicating extremely uneven atomization.

[0071] Comparative Example 3

[0072] In this example, compared with Example 1, the non-Newtonian fluid medium 25 was not filled in the sleeve 28 of this example, and the rest were the same.

[0073] During the test process of this example, it was found that in the test seasoning soup used, the sodium chloride content was 0.9%, the solid content was 30%, and the water-soluble red pigment content was 0.1%; no clogging occurred. However, the average sodium content was 578 mg and the variance value was 156507, indicating extremely uneven atomization.

[0074] As can be seen from Comparative Examples 2 and 3, if the non-Newtonian fluid medium 25 is not used as the coupling medium, it is impossible to ensure uniform atomization.

[0075] Comparative Example 4

[0076] Based on Example 1, during the variation tests of f1, f2, and f3, it was found that when the ultrasonic frequency varied within the range of 20 - 65 kHz and the megasonic frequency varied within the range of 1000 - 2000 kHz, in the flavor soup used for testing, the sodium chloride content was 0.9%, the solid content was 9.3%, and the water-soluble red pigment content was 0.1%; no blockage occurred. However, the atomization uniformity effects were different.

[0077] The relevant test results are shown in Table 2:

[0078] Table 2

[0079]

[0080]

[0081] In Table 2, when f1 = f2 = f3 = 0, it means that the corresponding ultrasonic transducer 1 - 31, megasonic transducer 32, and ultrasonic transducer 2 - 33 are all not working.

[0082] As can be seen from Table 2, when the operating frequency of the ultrasonic transducer 1 - 31 is 26 kHz, the operating frequency of the megasonic transducer 32 is 1576 kHz, and the operating frequency of the ultrasonic transducer 2 - 33 is 1576 kHz, it also meets the usage requirements.

[0083] In addition, through summarizing a large amount of test data, when f1·f1 + f3·f3 = f2 (without considering the change of dimension), at this frequency, it is easier to couple, and the atomization uniformity effect is excellent.

[0084] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
