Description

Technical Field

[0001] This utility model relates to the field of agricultural product processing technology, and in particular to a graded freezing packaging device for morel mushrooms. Background Technology

[0002] Morel mushrooms, a rare and precious edible fungus, have gained immense popularity in domestic and international markets in recent years due to their unique flavor, rich nutritional value, and high medicinal value. With the maturation of artificial cultivation techniques, morel production has increased year by year, placing higher demands on post-harvest processing and preservation technologies. Grading and packaging are indispensable key steps in the commercialization of morel mushrooms, directly affecting product quality, shelf life, and market competitiveness.

[0003] Currently, most common morel mushroom grading devices on the market use vibration grading. However, morel mushrooms are delicate and have a honeycomb-like surface structure. During vibration, they are easily damaged by collisions and friction, resulting in broken caps, broken stems, or surface tissue damage. This not only affects the appearance quality but may also lead to microbial infection and accelerate spoilage.

[0004] Secondly, most existing grading devices do not integrate freezing functions, meaning that morel mushrooms still need to undergo traditional sun-drying or hot-air drying after grading before subsequent packaging and storage. While this processing method can extend shelf life, it significantly reduces the volatile aroma components, protein activity, and polysaccharides in morel mushrooms, resulting in poor freshness.

[0005] Therefore, it is necessary to provide a graded frozen packaging device specifically for morel mushrooms to solve the problems mentioned in the background art. Utility Model Content

[0006] To address the aforementioned problems, this application provides a special grading and freezing packaging device for morel mushrooms, thereby solving the issues of inability to grade without damage and inability to quickly freeze and preserve freshness mentioned in the background art.

[0007] To achieve the objectives of this application, the following technical solution is provided:

[0008] This application provides a graded frozen packaging device for morel mushrooms, comprising: a lifting and conveying mechanism, a separating mechanism, and a grading mechanism. A buffer trough is fixedly installed on the upper end of one side of the lifting and conveying mechanism, and a separating mechanism is fixedly installed on the upper end of the other side of the lifting and conveying mechanism. The separating mechanism includes a slide groove fixedly installed with the lifting and conveying mechanism. Inclined guide plates are symmetrically fixedly installed on the front and rear sides of the upper end of the slide groove. Multiple inverted V-shaped guide plates are evenly fixedly installed on the slide groove between the inclined guide plates. A grading mechanism is provided at the lower end of the separating mechanism. The grading mechanism includes a first rotating shaft, a second rotating shaft, a third rotating shaft, and a fourth rotating shaft rotatably mounted on a support. Multiple sorting belts, corresponding to the inclined guide plate and the inverted V-shaped guide plate, are wound around the first rotating shaft, the second rotating shaft, the third rotating shaft, and the fourth rotating shaft. n first conveying mechanisms are transversely inserted between the sorting belts. Each of the first conveying mechanisms has a second conveying mechanism at its conveying end. The second conveying mechanisms are all inserted into a freezing tunnel, and a packaging mechanism is installed below each conveying end of the freezing tunnel.

[0009] In one possible implementation, the lower end spacing of adjacent inclined guide plates and inverted V-shaped guide plates, and the lower end spacing of adjacent inverted V-shaped guide plates are all set to correspond to the spacing of adjacent sorting belts.

[0010] In one possible implementation, each of the output ends of the freezing tunnel is fixedly equipped with a discharge hopper, and each discharge hopper is fixedly equipped with a Y-shaped guide plate, the discharge port of the Y-shaped guide plate being correspondingly set with the inlet of the packaging mechanism.

[0011] In one possible implementation, the grading mechanism further includes a motor fixedly mounted on the bracket, with a driving grooved wheel fixedly mounted circumferentially at the output end of the motor, and a driven grooved wheel fixedly mounted circumferentially on one side of the first rotating shaft extending out of the bracket, the driving grooved wheel and the driven grooved wheel being connected by a belt drive.

[0012] In one possible implementation, a plurality of evenly distributed first annular isolation wheels are fixedly arranged circumferentially on the first rotating shaft located between the supports; a plurality of evenly distributed second annular isolation wheels are fixedly arranged circumferentially on the second rotating shaft located between the supports; a plurality of evenly distributed third annular isolation wheels are fixedly arranged circumferentially on the third rotating shaft located between the supports; and a plurality of evenly distributed fourth annular isolation wheels are fixedly arranged circumferentially on the fourth rotating shaft located between the supports. The sorting belt is provided between adjacent first annular isolation wheels, adjacent second annular isolation wheels, adjacent third annular isolation wheels, and adjacent fourth annular isolation wheels.

[0013] In one possible implementation, the distances between adjacent first and second annular isolation wheels are equal, the distances between adjacent third and fourth annular isolation wheels are equal, and the axial lengths of adjacent third annular isolation wheels are all greater than the axial lengths of adjacent first annular isolation wheels.

[0014] In one possible implementation, (n-1) guide plates are horizontally fixed on the support located between the sorting belts, and the guide plates are all located at the upper end of the adjacent first conveying mechanism.

[0015] In one possible implementation, the lower end of the sorting belt located at the upper end of the guide plate is spaced 6-8 cm apart from the upper end of the first conveying mechanism.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model uses an output lifting mechanism to transport morel mushrooms to a sorting mechanism. Then, using inclined guide plates and inverted V-shaped guide plates, the morel mushrooms slide along their length into the sorting belt. The rotating sorting belt and the gradually increasing gap between the sorting belts grade morel mushrooms of different sizes. The graded morel mushrooms are then sent out along the first conveying mechanism. This allows for precise classification based on the actual size of the morel mushrooms in a gentle manner, avoiding surface damage caused by violent vibration in traditional vibrating screens. This protects the fragile surface structure of the morel mushrooms and ensures that each individual mushroom can be accurately evaluated and classified, thus improving grading accuracy.

[0018] 2. In this utility model, after the morel mushrooms are graded, they are conveyed to the second conveyor via the first conveyor mechanism. Then, the morel mushrooms are rapidly frozen using a freezing tunnel. After freezing, the morel mushrooms are packaged using a packaging mechanism. Rapid freezing can quickly lower the temperature of the morel mushrooms, reduce the damage to the cell structure caused by ice crystal formation, and thus better preserve their original flavor, taste and nutritional value, ensuring the freshness of the product.

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature; in the description of this application, unless otherwise stated, "multiple" means three or more.

[0027] Figures 1-4A grading and freezing packaging device for morel mushrooms provided in this application includes: a lifting and conveying mechanism 1, a slitting mechanism 3, and a grading mechanism 4. A buffer trough 2 is fixedly installed on the upper end of one side of the lifting and conveying mechanism 1, and a slitting mechanism 3 is fixedly installed on the upper end of the other side of the lifting and conveying mechanism 1. The slitting mechanism 3 includes a slide groove 31 fixedly installed with the lifting and conveying mechanism 1. Inclined guide plates 32 are symmetrically fixedly installed on the front and rear sides of the upper end of the slide groove 31. Multiple inverted V-shaped guide plates 33 are evenly fixedly installed on the slide groove 31 between the inclined guide plates 32. A grading mechanism 4 is installed at the lower end of the slitting mechanism 3. The structure 4 includes a first rotating shaft 404, a second rotating shaft 408, a third rotating shaft 410, and a fourth rotating shaft 412, which are rotatably mounted on the support 401. Multiple sorting belts 414, corresponding to the inclined guide plate 32 and the inverted V-shaped guide plate 33, are wound around the first rotating shaft 404, the second rotating shaft 408, the third rotating shaft 410, and the fourth rotating shaft 412. n first conveying mechanisms 5 are transversely inserted between the sorting belts 414. A second conveying mechanism 6 is provided at the conveying end of each of the first conveying mechanisms 5. The second conveying mechanisms 6 are all inserted into the freezing tunnel 7. A packaging mechanism 8 is provided below the conveying end of each of the freezing tunnel 7.

[0028] It should be added that the conveyor belt of the lifting conveyor mechanism 1 is a conveyor belt with baffles. During the rotation of the conveyor belt and baffles, the morel mushrooms in the buffer tank 2 can be transported to the sorting mechanism 3. Secondly, the freezing tunnel 7 can use ammonia as a refrigerant, which circulates under the action of the compressor, releases heat through the condenser, and then enters the evaporator through the expansion valve to absorb heat, thereby achieving a cooling effect. At the same time, the freezing tunnel 7 can also cool the air to the required temperature through mechanical refrigeration, and then use a fan to blow the cold air into the freezing tunnel 7 to cool the morel mushrooms. The first conveyor mechanism 5 is a conventional conveyor belt, while the conveyor belt of the second conveyor mechanism 6 is equipped with mesh. The mesh ensures that the cold air can fully contact the surface of the morel mushrooms. In addition, the lifting conveyor mechanism 1, the first conveyor mechanism 5, the second conveyor mechanism 6, the freezing tunnel 7 and the packaging mechanism 8 are all existing technologies and will not be described in detail.

[0029] It should be noted that in this application, the conveyor belts of adjacent first conveying mechanisms 5 rotate in opposite directions, such as... Figure 1 The diagram shows three first conveying mechanisms 5 as an example. The first conveying mechanisms 5 on both sides rotate clockwise to convey morel mushrooms to the corresponding second conveying mechanism 6, and the corresponding second conveying mechanism 6 rotates clockwise to convey morel mushrooms to the corresponding packaging mechanism 8 for packaging. The first conveying mechanism 5 in the middle rotates counterclockwise to convey morel mushrooms to the corresponding second conveying mechanism 6, and the corresponding second conveying mechanism 6 rotates counterclockwise to convey morel mushrooms to the corresponding packaging mechanism 8 for packaging.

[0030] Through the above technical solution, the lifting conveyor 1, grading mechanism 4, first conveyor 5, second conveyor 6, freezing tunnel 7, and packaging mechanism 8 are activated to transport the morel mushrooms to be graded into the buffer tank 2. The lifting conveyor 1 then transports the morel mushrooms onto the chute 31. The morel mushrooms then slide down along the length direction through the inclined guide plate 32 and the inverted V-shaped guide plate 33 to the sorting belt 414. The rotating sorting belt 414 grades the morel mushrooms, allowing for precise classification based on their actual size in a gentle manner, avoiding the violent shaking caused by traditional vibrating screening. The surface damage caused by vibration protects the fragile surface structure of morel mushrooms and ensures that each individual mushroom can be accurately assessed and classified, thus improving grading accuracy. After grading, the morel mushrooms fall onto the first conveyor 5, which then transports them to the second conveyor 6 for freezing in the freezing tunnel 7. The frozen morel mushrooms are then transported to the packaging mechanism 8 for packaging. Rapid freezing can quickly lower the temperature of the morel mushrooms, reduce the damage to the cell structure caused by ice crystal formation, and thus better preserve their original flavor, taste and nutritional value, ensuring the freshness of the product.

[0031] In one possible implementation, the lower end spacing of adjacent inclined guide plates 32 and inverted V-shaped guide plates 33, and the lower end spacing of adjacent inverted V-shaped guide plates 33, are all set to correspond to the spacing of adjacent sorting belts 414, so that morel mushrooms sliding down from between adjacent inclined guide plates 32 and inverted V-shaped guide plates 33 or between adjacent inverted V-shaped guide plates 33 on the slide groove 31 can fall into the adjacent sorting belts 414 and be sorted by the rotating sorting belts 414.

[0032] In one possible implementation, each of the output ends of the freezing tunnel 7 is fixedly equipped with a discharge hopper 9, and each of the discharge hoppers 9 is fixedly equipped with a Y-shaped guide plate 10. The discharge port of the Y-shaped guide plate 10 is correspondingly set with the inlet of the packaging mechanism 8, so that the frozen morel mushrooms can be transported along the discharge hopper 9 and the Y-shaped guide plate 10 to the packaging mechanism 8 for packaging.

[0033] In one possible implementation, the grading mechanism 4 further includes a motor 402 fixedly mounted on the bracket 401. A drive pulley 403 is fixedly mounted circumferentially at the output end of the motor 402, and a driven pulley 405 is fixedly mounted circumferentially on one side of the first rotating shaft 404 extending out of the bracket 401. The drive pulley 403 and the driven pulley 405 are connected by a belt 406.

[0034] Using the above technical solution, after starting the motor 402, the active grooved wheel 403 drives the driven grooved wheel 405 and the first rotating shaft 404 to rotate via the belt 406, and the first rotating shaft 404 then drives the sorting belt 414 to rotate.

[0035] In one possible implementation, a plurality of evenly distributed first annular isolation wheels 407 are fixedly arranged circumferentially on the first rotating shaft 404 located between the supports 401; a plurality of evenly distributed second annular isolation wheels 409 are fixedly arranged circumferentially on the second rotating shaft 408 located between the supports 401; a plurality of evenly distributed third annular isolation wheels 411 are fixedly arranged circumferentially on the third rotating shaft 410 located between the supports 401; and a plurality of evenly distributed fourth annular isolation wheels 413 are fixedly arranged circumferentially on the fourth rotating shaft 412 located between the supports 401. The sorting belts 414 are arranged between adjacent first annular isolation wheels 407, adjacent second annular isolation wheels 409, adjacent third annular isolation wheels 411, and adjacent fourth annular isolation wheels 413, respectively. That is, multiple sorting belts 414 can rotate between corresponding adjacent first annular isolation wheels 407, adjacent second annular isolation wheels 409, and adjacent third annular isolation wheels 411.

[0036] In one possible implementation, the distances between adjacent first annular isolation wheels 407 and adjacent second annular isolation wheels 409 are equal, the distances between adjacent third annular isolation wheels 411 and adjacent fourth annular isolation wheels 413 are equal, and the axial lengths of adjacent third annular isolation wheels 411 are all greater than the axial lengths of adjacent first annular isolation wheels 407, such that the gap between the sorting belts 414 gradually increases from the direction close to the sorting mechanism 3 to the direction away from the sorting mechanism 3.

[0037] It needs to be explained that the cap of morel mushrooms is oval or egg-shaped with a blunt, rounded apex, measuring 4-8 cm in length and 3-6 cm in diameter. Its surface has numerous small pits, resembling a sheep's stomach. These pits are irregularly shaped or nearly circular, brownish-red, and 4-12 mm in diameter, with yellowish-brown ridges. The stipe is nearly cylindrical, 5.5-8 cm in length and 2-4 cm in diameter. That is, the spacing between adjacent sorting belts 414, from near the sorting mechanism 3 to away from it, can continuously increase from 2-8 cm. This allows morel mushrooms to slide down the inclined guide plate 32 and each inverted V-shaped guide plate 33 along their length into the sorting belts 414, where they are then graded according to their different sizes by the rotating sorting belts 414.

[0038] In one possible implementation, (n-1) guide plates 415 are horizontally fixed on the support 401 located between the sorting belts 414. The guide plates 415 are all located at the upper end of the adjacent first conveying mechanism 5, and the graded morel mushrooms can fall onto the first conveying mechanism 5 along the guide plates 415.

[0039] In one possible implementation, the lower end of the sorting belt 414 located at the upper end of the guide plate 415 is positioned 6-8 cm away from the upper end of the first conveying mechanism 5.

[0040] Through the above technical solution, the morel mushrooms slide down along the length direction to the sorting belt 414, and then are graded by the rotating sorting belt 414 and the gradually increasing gap between the sorting belts 414. The caps of the graded morel mushrooms fall onto the first conveying mechanism 5 at a relatively low height along the guide plate 415, so that the morel mushrooms can be directly and smoothly conveyed by the first conveying mechanism 5, effectively avoiding surface damage caused by the large drop of the morel mushroom caps and stems, and ensuring their integrity.

[0041] Working principle:

[0042] The lifting conveyor 1, the first conveyor 5, the second conveyor 6, the freezing tunnel 7, the packaging mechanism 8, and the motor 402 are activated to transport the morel mushrooms to be graded into the buffer tank 2. The lifting conveyor 1 transports the morel mushrooms onto the slide chute 31. The morel mushrooms then slide down along the length direction through the inclined guide plate 32 and the inverted V-shaped guide plate 33 to the sorting belts 414. The rotating sorting belts 414 and the gradually increasing gaps between the sorting belts 414 grade the morel mushrooms. The graded morel mushrooms fall onto the first conveyor 5 along the guide plate 415. The first conveyor 5 transports the morel mushrooms to the second conveyor 6 and freezes them in the freezing tunnel 7. The frozen morel mushrooms are then transported along the discharge hopper 9 and the Y-shaped guide plate 10 to the packaging mechanism 8. Finally, the packaging mechanism 8 packages the morel mushrooms.

[0043] The above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit it. This application is not limited to the exact structures described above and illustrated in the accompanying drawings, and it should not be considered that the specific implementation of this application is limited to these descriptions. For those skilled in the art, various changes and modifications made without departing from the concept of this application should be considered to fall within the protection scope of this application.
