Description

Technical Field

[0001] The invention belongs to the technical field of seed preservation, and particularly relates to a device for preserving trichosanthes seeds. Background Art

[0002] Trichosanthes kirilowii is also called medicinal melon, and its scientific name is Trichosanthes kirilowii. The melon shell of Trichosanthes kirilowii can be used as medicine, and the mature Trichosanthes kirilowii seeds can be used as health food after being dried, while the roots of Trichosanthes kirilowii can be made into Radix Trichosanthis, which has great utilization value and high economic benefits.

[0003] In the deep processing of Trichosanthes seeds, Trichosanthes kernels (seed kernels obtained after shelling Trichosanthes seeds) can be pressed for oil, or further processed into Trichosanthes seed frost. The functions of Trichosanthes seed frost are: clearing heat and phlegm, relieving chest congestion, moistening intestines and relieving constipation. It is used for phlegm-heat cough, lung abscess vomiting pus, chest pain, chest congestion, breast abscess, dry intestines and constipation.

[0004] Because of this, the storage of Trichosanthes seeds as an important raw material is very important. At present, the guarantee of Trichosanthes seeds is usually stored in a silo; generally, a ventilation pipe is set inside the silo to ventilate and dissipate heat in the silo.

[0005] However, in rainy seasons, the humidity inside the silo is high. Even if the Trichosanthes seeds in the silo are regularly dried with hot air, the silo is usually tens of meters or dozens of meters high, and the internal area cannot be 100% completely dried, which makes it easy for mold to grow in some areas.

[0006] For sterilization in silos, the commonly used technical means is to use fumigation gas for fumigation. Fumigation gas refers to a gas with bactericidal effect. Commonly used ones include ethylene oxide, phosphine, methyl bromide, bromoformaldehyde, propylene oxide, etc. Its sterilization principle is to use alkylation to inert the substances that are indispensable for maintaining life in microbial tissues. The most commonly used is a mixture of ethylene oxide and carbon dioxide prepared in different proportions. Aeration of fumigation gas into the silo usually uses a fixed aeration pipe or aeration head.

[0007] The above technology has the following defects:

[0008] 1. Fumigation gases mainly composed of ethylene oxide, phosphine, methyl bromide, bromoformaldehyde, and propylene oxide are not suitable for large-scale continuous processing of food and medicine, and cannot be used as needed; after taking out the Trichosanthes seeds from the silo, the seeds need to be spread out and ventilated to dissipate or remove the fumigation gas remaining on the surface of the seeds. This method is time-consuming, labor-intensive, and inefficient.

[0009] 2. When using aeration pipes or aeration heads for aeration, there will be some aeration dead corners or aeration weak areas, which is not conducive to the preservation of Trichosanthes seeds.

[0010] Based on this, the present invention is proposed. Summary of the invention

[0011] The object of the present invention is to provide a Trichosanthes seeds storage device to solve the above-mentioned problems.

[0012] A device for preserving trichosanthes seeds comprises a silo, a fumigation gas generator and a fumigation gas delivery pipeline. A plurality of multi-degree-of-freedom vibration aeration components are arranged in the silo. The fumigation gas generator generates fumigation gas and delivers the fumigation gas to the multi-degree-of-freedom vibration aeration components through the fumigation gas delivery pipeline. The fumigation gas is aerated toward the trichosanthes seeds stored in the silo through the multi-degree-of-freedom vibration aeration components. During aeration, the multi-degree-of-freedom vibration aeration components vibrate the surrounding trichosanthes seeds and simultaneously perform a swinging motion. The multi-degree-of-freedom vibration aeration components comprise a low-frequency vibration source and a megasonic vibration source. The vibration frequency of the low-frequency vibration source is less than or equal to 200 Hz, and the megasonic frequency of the megasonic vibration source is greater than or equal to 2.1 MHz.

[0013] A further improvement is that the multi-degree-of-freedom vibration aeration assembly includes a vibrating rod and six megasonic vibration rods surrounding the outer circumference of the vibrating rod, the vibrating rod includes a flexible rod segment and a hard rod segment, the flexible rod segment is fixedly connected to the bottom of the silo; the megasonic vibration rod is fixedly connected to the hard rod segment, the lower ends of the six megasonic vibration rods are arranged flush, and the heights of the six megasonic vibration rods are arranged to increase in sequence in a clockwise direction; the vibrating rod is a low-frequency vibration source, and the megasonic vibration rod is a megasonic vibration source.

[0014] As a further improvement, the six megasonic vibration rods are marked in clockwise direction as the first megasonic vibration rod, the second megasonic vibration rod, the third megasonic vibration rod, the fourth megasonic vibration rod, the fifth megasonic vibration rod and the sixth megasonic vibration rod, the height of the first megasonic vibration rod is a, the height of the second megasonic vibration rod is 2a, the height of the third megasonic vibration rod is 3a, the height of the fourth megasonic vibration rod is 4a, the height of the fifth megasonic vibration rod is 5a, and the height of the sixth megasonic vibration rod is 6a.

[0015] As a further improvement, the surfaces of the megasonic vibrating rod and the vibrating rod are provided with air holes, the interiors of the megasonic vibrating rod and the vibrating rod are provided with gas channels connected to the air holes, and the gas channels are connected to the fumigation gas delivery pipeline.

[0016] As a further improvement, a bowl-shaped plastic shell is fixedly mounted on the upper end of the vibrating rod.

[0017] As a further improvement, a double-hole hose is connected between the top of the plastic shell and the top of the silo, and the lower end of the double-hole hose extends into the bottom of the inner cavity of the plastic shell.

[0018] As a further improvement, the vibration frequency of the vibrating rod is 25-50 Hz.

[0019] As a further improvement, the megasonic frequency of the first megasonic vibration rod is 2.1 MHz, the megasonic frequency of the second megasonic vibration rod is 2.5 MHz, the megasonic frequency of the third megasonic vibration rod is 2.9 MHz, the megasonic frequency of the fourth megasonic vibration rod is 2.5 MHz, the megasonic frequency of the fifth megasonic vibration rod is 2.9 MHz, and the megasonic frequency of the sixth megasonic vibration rod is 2.5 MHz.

[0020] A further improvement also includes a cooling water source, wherein the water outlet end of the cooling water source is connected to one of the holes on the upper end of the double-hole hose, and the water return end of the cooling water source is connected to the other hole on the upper end of the double-hole hose.

[0021] As a further improvement, a ladder is installed on the outside of the silo, and a bottom support is installed on the bottom of the silo.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention uses fumigation gas to perform regular aeration sterilization on the Trichosanthes seeds stored in the silo, such as using ozone with a concentration of 50-100 mg / m³ for continuous ozone fumigation for 60 minutes every day, and the killing rate of natural bacteria in the silo reaches more than 90%; using ozone as the fumigation gas for sterilization, there is no residue, and the Trichosanthes seeds stored in the silo can be taken and used at any time, which is particularly suitable for the subsequent processing of the Trichosanthes seeds.

[0024] 2. When fumigation gas is used to perform regular aeration and sterilization on the Trichosanthes seeds stored in the silo, aeration is performed into the silo through a multi-degree-of-freedom vibration aeration component. During aeration, vibration is applied to the surrounding Trichosanthes seeds and swinging motion is performed at the same time. The aeration effect is good. Aeration is performed on the accumulated large volume of Trichosanthes seeds without aeration dead corners. In the process of ozone overflowing from the multi-degree-of-freedom vibration aeration component to the surrounding area, the ozone can be evenly distributed around with the help of the auxiliary vibration of the low-frequency vibration source and the megasonic vibration source, thereby significantly improving the uniformity of aeration.

[0034] Example 1

[0035] like Figure 1 , 2As shown, the Trichosanthes seeds storage device comprises a silo 10 for storing the Trichosanthes seeds; the Trichosanthes seeds storage device also comprises a fumigation gas generator and a fumigation gas delivery pipeline, a plurality of multi-degree-of-freedom vibration aeration components 30 are arranged in the silo 10, the fumigation gas generator generates fumigation gas and delivers it to the multi-degree-of-freedom vibration aeration component 30 through the fumigation gas delivery pipeline, the fumigation gas is aerated toward the Trichosanthes seeds stored in the silo 10 through the multi-degree-of-freedom vibration aeration component 30, the multi-degree-of-freedom vibration aeration component 30 applies vibration to the surrounding Trichosanthes seeds during aeration and performs swinging motion at the same time, the multi-degree-of-freedom vibration aeration component 30 comprises a low-frequency vibration source and a megasonic vibration source, the vibration frequency of the low-frequency vibration source is less than or equal to 200HZ, and the megasonic frequency of the megasonic vibration source is greater than or equal to 2.1MHz.

[0036] In this embodiment, the fumigation gas is ozone. The fumigation gas generator is an ozone generator, the ozone concentration in the fumigation gas delivery pipeline is 50-100 mg / m³, and the ozone fumigation is continuously performed for 60 minutes per day, and the killing rate of natural bacteria in the air and the silo 10 reaches more than 90%.

[0037] In the present invention, ozone oxidation sterilization is adopted without residue, and the Trichosanthes seeds stored in the silo 10 can be taken out and used at any time without waiting for other fumigant gases remaining on the surface of the Trichosanthes seeds to dissipate or be removed, which is more suitable for subsequent processing of food and medicine.

[0038] In this embodiment, the distribution density of the multi-degree-of-freedom vibration aeration assembly 30 is 3.5 pieces / m 2 , distribution density refers to the total number of multi-degree-of-freedom vibration aeration components 30 in the cross section of the silo 10 divided by the distribution density, which refers to the cross-sectional area of ​​the silo 10. In the simulation test, the height of the multi-degree-of-freedom vibration aeration component 30 is 1m, the height of the simulated silo (scaled down in proportion to the silo 10) is 1.2m, the inner diameter of the silo 10 is 2m, and the total number of multi-degree-of-freedom vibration aeration components 30 is 11.

[0039] Example 2

[0040] In Example 1, Figures 2~4 As shown, the multi-degree-of-freedom vibration aeration assembly 30 includes a vibrating rod 31 and six megasonic vibration rods surrounding the outer circumference of the vibrating rod 31, the vibrating rod 31 includes a flexible rod segment and a hard rod segment, the flexible rod segment is fixedly connected to the bottom of the silo 10; the megasonic vibration rod is fixedly connected to the hard rod segment, the lower ends of the six megasonic vibration rods are arranged flush, and the heights of the six megasonic vibration rods are arranged to increase in sequence in a clockwise direction; the vibrating rod 31 is a low-frequency vibration source, and the megasonic vibration rod is a megasonic vibration source.

[0041] The hard rod section of the vibrating rod 31 is the metal pipe section, and the flexible rod section is the cable section, and the cable section and the metal pipe section are connected as a whole; a common vibrating rod, such as a concrete vibrating rod.

[0042] In the present invention, by further improving the structures of the existing concrete vibrator and megasonic vibrator, the surfaces of the megasonic vibrator and the vibrator 31 are provided with air holes, the insides of the megasonic vibrator and the vibrator 31 are provided with gas channels connected to the air holes, and the gas channels are connected to the fumigation gas delivery pipeline.

[0043] In the present invention, firstly, due to the restraint of the flexible rod segment, when the hard rod segment vibrates at a low frequency and a large amplitude, it will exert a force on the surrounding Trichosanthes seeds. Under the action of the reaction force, it will swing with the connection point between the flexible rod segment and the bottom of the silo 10 as the base point. Therefore, in theory, the multi-degree-of-freedom vibration-type aeration component 30 can perform a 360° swing motion during aeration. Such a large range of swinging significantly increases the aeration range.

[0044] The six megasonic vibration rods are marked as a first megasonic vibration rod 321, a second megasonic vibration rod 322, a third megasonic vibration rod 323, a fourth megasonic vibration rod 324, a fifth megasonic vibration rod 325 and a sixth megasonic vibration rod 326 in a clockwise direction; the height of the first megasonic vibration rod 321 is a, the height of the second megasonic vibration rod 322 is 2a, the height of the third megasonic vibration rod 323 is 3a, the height of the fourth megasonic vibration rod 324 is 4a, the height of the fifth megasonic vibration rod 325 is 5a, and the height of the sixth megasonic vibration rod 326 is 6a.

[0045] The vibration frequency of the vibrating rod 31 cannot be precisely determined to a certain value, but is generally a range value, usually a low-frequency vibration frequency of 25-50 Hz, a medium-frequency vibration frequency of 83-133 Hz, and a high-frequency vibration frequency of 167-200 Hz; in the present embodiment, preferably, the vibration frequency of the vibrating rod 31 is 25-50 Hz.

[0046] The megasonic frequency of the first megasonic vibration rod 321 is 2.1 MHz, the megasonic frequency of the second megasonic vibration rod 322 is 2.5 MHz, the megasonic frequency of the third megasonic vibration rod 323 is 2.9 MHz, the megasonic frequency of the fourth megasonic vibration rod 324 is 2.5 MHz, the megasonic frequency of the fifth megasonic vibration rod 325 is 2.9 MHz, and the megasonic frequency of the sixth megasonic vibration rod 326 is 2.5 MHz.

[0047] Example 3

[0048] In Example 2, a bowl-shaped plastic shell 33 is fixedly mounted on the upper end of the vibrating rod 31. A double-hole hose is connected between the top of the plastic shell 33 and the top of the silo 10, and the lower end of the double-hole hose extends into the bottom of the inner cavity of the plastic shell 33.

[0049] The Trichosanthes seeds storage device also includes a cooling water source, the water outlet of the cooling water source is connected to one of the holes on the upper end of the double-hole hose, and the water return end of the cooling water source is connected to the other hole on the upper end of the double-hole hose.

[0050] Under the restriction of the plastic shell 33 and the double-hole hose, the defect that the multi-degree-of-freedom vibration aeration component 30 cannot be reset due to excessive swinging can be avoided.

[0051] The cooling water in the cooling water source has a temperature of 1-5°C, and flows into / out of the plastic shell 33 through a double-hole hose, which can cool the multi-degree-of-freedom vibration aeration assembly 30 and the Trichosanthes seeds around it. On the one hand, it can cool the heat accumulated in the low-frequency vibration source and the megasonic vibration source during vibration. On the other hand, it can also be used to cool the silo 10 in summer.

[0052] Example 4

[0053] In Example 2, for the convenience of maintenance, a ladder 20 is further installed on the outside of the silo 10. A bottom support 21 is also installed at the bottom of the silo 10.

[0054] Comparative Example 1

[0055] In this example, the only difference from Example 3 is that the low-frequency vibration source and the megasonic vibration source are not started, and the rest are the same.

[0056] Comparative Example 2

[0057] In this example, the only difference from Example 3 is that the megasonic vibrating rods are replaced by vibrating rods, the frequencies of all vibrating rods are 25-50 Hz, and the rest are the same.

[0058] Comparative Example 3

[0059] In this example, the only difference from Example 3 is that the heights of the six megasonic vibration rods are equal, and the rest are the same.

[0060] Comparative Example 4

[0061] In the experiment of this example, the megasonic vibration rod was replaced with an ultrasonic vibration rod. It was found in the experiment that ultrasound had a great influence on the Trichosanthes seed test samples. By adjusting the ultrasonic frequency, it was found that whether in the range of 20kHz~100kHz, in the process of ultrasonic vibration lasting up to 60 minutes, some of the Trichosanthes seed test samples would cause cracks. The closer to the source of ultrasound, the more cracks there were in the Trichosanthes seed test samples.

[0062] 《Test for characterization of vibration effects in silos》

[0063] The dried Trichosanthes seeds (water content of 9%±0.2%) are immersed in a phenol solution with a mass fraction of 1% for 15 seconds, taken out, placed in a vibrating screen to filter water and blow-dried (a hair dryer is used to aim at the vibrating screen for drying) for 30 minutes to obtain a Trichosanthes seed test sample; the scrapings of the Trichosanthes seed test sample are scraped with a scraper, and the content thereof is measured by spectrophotometry to be 715-786 mg / 100 g; the peel or pulp of fruits generally contains phenol, and the present invention uses phenol as a labeling reagent, which is easily oxidized by ozone, so if it is in a vibration dead angle or weak area, the degree of oxidation by ozone is small, so the phenol content of the scrapings on the surface of the Trichosanthes seed test sample after vibration sterilization can be detected in the subsequent detection to understand whether there is a vibration dead angle or weak area. In addition, during the test, the surface of the Trichosanthes seeds test sample has a certain amount of moisture, which can not only be used to simulate the Trichosanthes seeds soaked by rain in the rainy season or condensed water in the winter, but also the wet Trichosanthes seeds test sample is more sensitive to vibration (such as ultrasonic vibration), which can be used to simulate the vibration resistance of Trichosanthes seeds.

[0064] η is the degradation rate of phenol on the surface of the Trichosanthes seed test sample, η=the difference between the phenol content of the scraped surface of the Trichosanthes seed test sample before vibration sterilization and the phenol content of the scraped surface of the Trichosanthes seed test sample after vibration sterilization / the phenol content of the scraped surface of the Trichosanthes seed test sample before vibration sterilization; the larger the η value, the higher the degree of ozone oxidation of the Trichosanthes seed test sample in this area, the better the vibration effect at this location, which is conducive to the passage of ozone.

[0065] Sampling rules: Through long-term observation and summary of 10 fixed-point sampling areas prone to mold growth by our technical staff, long-handled sampling cups are set up at these locations for fixed-point sampling, and the η value corresponding to each sampling point is measured and calculated as η s ; In addition, randomly sample 15 points, measure and calculate the η value of each sampling point, and take the average as η0; if η s ≥η0, indicating that the vibration effect of the fixed-point sampling area is good; if η s<η0, indicating that the vibration effect of the fixed-point sampling area is poor; the total number of fixed-point sampling areas with poor vibration effect is n1, and the proportion of vibration dead angle area is y=n1 / 10. The larger the proportion of vibration dead angle area y, the more vibration dead angle areas there are, and the worse the aeration effect in the silo 10.

[0066] In addition, after multiplying the η values ​​of the 25 sampling points by 100, the variance value d is calculated. The larger d is, the worse the uniformity of ozone distribution in the silo 10 during aeration, resulting in excessive ozone distribution in some areas causing waste, insufficient ozone distribution in some areas, and requiring ozone to be introduced for a longer time to achieve the sterilization effect; the ozone content in some areas is negligible, close to zero, and these areas are vibration dead angles or weak areas.

[0067] In the reference test, ozone was replaced by air to test the natural oxidation of phenol in air. In the test environment of the present invention, the average of all η values ​​calculated was η i According to the test conditions of Example 3, η i =13.1%.

[0068] The test results of Example 3 and Comparative Examples 1 to 3 are shown in Table 1:

[0069] Table 1

[0070] <![CDATA[η0(%)]]> y（%） d Example 3 69.5 0 19.76 Comparative Example 1 51.3 100 481.20 Comparative Example 2 27.1 / / Comparative Example 3 60.8 0 273.42

[0071] As shown in Table 1, the use of megasonic vibrating rods in combination with vibrating rods can significantly expand the aeration range, thereby improving the sterilization effect. For the six megasonic vibrating rods, their heights are increased in a spiral manner, which makes the shock waves formed by the vibration more penetrating in the accumulated Trichosanthes seeds, thereby making the aeration effect more uniform.

[0072] Comparative Example 5

[0073] In this example, the only difference from Example 3 is that the megasonic frequencies of the six megasonic vibration rods are all equal, namely 2.1 MHz, 2.5 MHz, and 2.9 MHz, and the corresponding y and d are shown in Table 2:

[0074] Table 2

[0075] Megasonic frequency (MHz) y（%） d 2.1 70 117.58 2.5 40 135.25 2.9 60 120.91

[0076] Comparative Example 6

[0077] In this example, the only difference from Example 3 is that the megasonic frequency of the first megasonic vibration rod 321 is 2.1 MHz, the megasonic frequency of the second megasonic vibration rod 322 is 2.5 MHz, the megasonic frequency of the third megasonic vibration rod 323 is 2.9 MHz, the megasonic frequency of the fourth megasonic vibration rod 324 is 3.3 MHz, the megasonic frequency of the fifth megasonic vibration rod 325 is 3.7 MHz, and the megasonic frequency of the sixth megasonic vibration rod 326 is 4.1 MHz; the rest are the same. Finally, y=50%, d=303.63.

[0078] It can be seen from Comparative Examples 5 and 6 that the megasonic frequency distribution of the megasonic vibration rod will significantly affect y, but the degree of influence on d is not much different.

[0079] Comparative Example 7

[0080] In the experiment of this example, it was found that if the vibration frequency of the vibrating rod 31 is controlled at 83-133 Hz, the distribution density of the multi-degree-of-freedom vibration aeration assembly 30 needs to be increased to 4.1 pieces / m 2 , in order to make y=0, d≤20. If the vibration frequency of the vibrating rod 31 is controlled at 167~200Hz, even if the distribution density of the multi-degree-of-freedom vibration aeration assembly 30 is increased to 6.4 pieces / m 2 , d is still greater than 50. Therefore, preferably, the vibration frequency of the vibrating rod 31 is 25-50 Hz.

[0081] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
