Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aquatic product processing, in particular to a silver film preservation spraying machine for Trichiurus haumela. BACKGROUND

[0002] Trichiurus haumela is an economic fish in coastal areas of China, and its body surface is covered with a silver film. The silver film is mainly composed of guanine crystals, unsaturated fatty acids and natural antioxidants. It not only gives Trichiurus haumela a unique appearance color, but also forms a physical barrier to resist microbial invasion and reduce water loss and oxidation of fish meat. Therefore, the silver film affects the preservation of Trichiurus haumela and the appearance of the product for sale. After being caught by fishing boats, Trichiurus haumela is usually preserved. Common methods include immersion in preservatives or low-temperature freezing. However, manual immersion or ordinary spraying equipment is often used for immersion in preservatives, which has low efficiency, uneven use of preservatives, and easy damage to the silver film. Ordinary spraying equipment lacks specificity, and existing aquatic product preservation spraying equipment is mainly designed for small or sheet-shaped aquatic products such as shrimp and fish fillets. Low-temperature freezing technology can damage the taste of Trichiurus haumela and cause damage to the silver film when it is thawed. There are drawbacks in the existing preservation methods for Trichiurus haumela. Related technologies have been improved, such as the fish fillet icing preservation method proposed in the existing patent technology KR1020250162055A, which forms an ice coating by spraying water and combines with pine needle coating liquid. Although it can extend the preservation period, this method is designed for fish fillets and requires freezing treatment. The coating liquid is attached by immersion, which is not suitable for whole fish silver film protection. The shrimp preservation method disclosed in the existing patent technology LU502030B1 uses ozone water, acid electrolytic water and tea polyphenol solution for step-by-step immersion to achieve preservation. However, it relies on the bacteriostatic effect of chemical reagents, and the immersion method also has the risk of silver film falling off due to water flow impact or friction with the container during the immersion process. Therefore, based on the current preservation technology for Trichiurus haumela, there is still room for improvement in how to adapt to the slender body shape of Trichiurus haumela, achieve non-damaging protection of the silver film, and uniformly and low-costly spray preservatives.

Meanwhile, the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below in combination with the embodiments and with reference to the drawings. Embodiment 1

[0021] As shown in the drawings Figure 1 -attached Figure 7 The silver film preservation spraying machine for hairtail includes a spraying plate 10, a spraying assembly 20 is arranged above the spraying plate 10, the spraying plate 10 is arranged obliquely and is provided with a filtering assembly 30 below, the filtering assembly 30 includes a collecting box 36 with an upper opening, a filtering box 31 is arranged below the collecting box 36, an outlet of the collecting box 36 is connected with an inlet pipe 39 on the filtering box 31 through a first conveying pipe 37, one end of the inlet pipe 39 is arranged in the filtering box 31, and the other end is arranged outside the filtering box 31, the filtering box 31 is internally provided with an inner cylinder 313 with filtering holes, the outlet of the inlet pipe 39 is located inside the inner cylinder 313, and the filtering box 31 is externally provided with a driving motor 33 connected with the inner cylinder 313.

[0022] For small and medium-sized fishing vessels, if hairtail is not selected for low-temperature freezing, artificial immersion or spraying treatment is needed to ensure the appearance of hairtail, and both artificial immersion and spraying have certain disadvantages, such as different residual degrees of preservatives on hairtail in immersion, and the risk of silver film rubbing and damage in the immersion process. More importantly, both immersion and spraying use a large amount of preservatives, increase the preservation cost, and if the preservatives are simply filtered and recovered, impurities are likely to be left, affecting the subsequent preservation of hairtail. Therefore, the spraying plate 10 is arranged obliquely and the spraying assembly 20 is arranged on the upper part of the spraying plate 10, so as to avoid local accumulation or leakage of the preservatives and reduce the compression damage to the silver film of the hairtail. In this way, the hairtail is placed on the spraying plate 10 in turn for spraying, and the excess preservatives after spraying are collected through the upper opening of the collecting box 36, and then sent to the inlet pipe 39 of the filtering box 31 through the first conveying pipe 37. The driving motor 33 drives the inner cylinder 313 to rotate, and the preservatives and impurities are separated through the filtering holes of the inner cylinder 313. In this way, the problems of difficult recovery of preservatives and easy pollution of preservatives by impurities are solved, and the recovered preservatives exist the problem of secondary pollution of hairtail or affect the appearance of hairtail.

[0023] The inner cylinder 313 is open at one end, and the inner bottom of the filter box 31 in the open direction is provided with a first output pipe 38. The outlet of the feed pipe 39 is located at the end of the inner cylinder 313 away from the opening.

[0024] During the spraying operation, the impurity-containing preservative in the feed pipe 39 enters from the distal end of the inner cylinder 313. Under the rotation driven by the driving motor 33, the impurities move along the inner wall of the inner cylinder 313 to the open end and separate. In this way, the separated preservative penetrates into the bottom of the filter box 31 through the filter hole of the inner cylinder 313, is discharged through the discharge box 310, and enters the storage tank 50. The impurities move along the inner wall of the inner cylinder 313 to the open end and then enter the output pipe 38 and are discharged, thereby solving the problem of recycling the preservative during spraying and enabling centralized treatment of the separated substances. The subsequent storage tank 50 is subjected to secondary filtration, thereby reducing the probability of clogging of the spraying assembly 20.

[0025] The inner wall of the inner cylinder 313 is provided with a spiral guide vane 311. The inner cylinder 313 is a rotary body structure with its axis horizontally arranged. The filter box 31 below the inner cylinder 313 is provided with a discharge box 310 in communication with the inside of the filter box 31. When the driving motor 33 drives the rotation of the inner cylinder 313, the guide vane 311 forms a spiral channel, thereby guiding the impurity-containing preservative to move smoothly along the axis direction of the inner cylinder 313, while enhancing the centrifugal separation effect. The preservative penetrates through the filter hole of the inner cylinder 313, is discharged through the discharge box 310, and enters the preservative recycling cycle. The impurities are pushed by the guide vane 311 and are discharged through the first output pipe 38. In this way, the problem of impurity retention and incomplete separation is solved, and the probability of clogging of the spraying assembly 20 is reduced.

[0026] The outlet of the feeding pipe 39 is provided with a buffer bottom plate 314 with a slope, the surface of the buffer bottom plate 314 is provided with a bending state and a vertical arranged guide plate 315, the guide plate 315 is connected with the feeding pipe 39 through a connecting strip plate 312, and the outlet of the feeding pipe 39 is arranged towards the buffer bottom plate 314, so that the flowing preservative can slow down the impact speed through the buffer bottom plate 314 first, and then be uniformly distributed to the inside of the inner cylinder 313 through the guide plate 315. Through this flow path, the mixed solution of the entering preservative and impurities is dispersed and falls on the inner cylinder 313, so as to increase the effective contact area of the dispersed mixed solution of the preservative and impurities with the inner cylinder 313, avoid the mixed solution of the preservative and impurities from falling on the same area of the inner cylinder 313 to weaken the separation effect, and the mixed solution of the preservative and impurities contacts the buffer bottom plate 314 and the guide plate 315 first after being discharged, and the impurities and the liquid can be separated once in the upper part, the flow speed of the impurities and the fluid medium is different, which helps the medium to be discharged from the buffer bottom plate 314 and the guide plate 315 first, so that the concentration effect of the impurities is better after the subsequent preservative and impurities fall on the inner cylinder 313, and the probability of the impurities adhering to the inner wall of the inner cylinder 313 is increased.

One of the rubber columns is connected with the collection box 36, and at least two elastic columns 35 are arranged at intervals on the collection box 36. During the artificial spraying process of the hairtail, the sprayed liquid is collected into the collection box 36 along the inclined strip-shaped groove 12 and the guide plate 13 of the spraying plate 10 as the number of processed products increases. In this process, the hairtail tissues or other small marine products or impurities and the like may be left on the spraying plate 10. Artificial cleaning can be performed by air spraying through the spraying assembly 20, or the hairtail tissues or other small marine products or impurities and the like can be shaken off into the collection box 36 by swinging the spraying plate 10.

The strip-shaped groove 12 guides the preservative to be evenly distributed along the groove body, avoiding local accumulation and pressing the silver film of the belt fish. The spraying plate 10 is arranged in an inclined state, which can accelerate the flow of excess preservative to the guide plate 13. The preservative enters the collecting box 36 through the gap in the middle part of the guide plate 13, thereby solving the problems of spraying blind area and silver film damage caused by uneven distribution of preservative, and improving the collection efficiency of preservative. The upper end of the inclined surface of the spraying plate 10 is sleeved with a sleeve 11, the axis of the sleeve 11 is parallel to the surface of the spraying plate 10, and the sleeve 11 can be replaced by a plate body structure.

The lower surface of the spraying plate 10 can be in contact with or separated from the first limiting rod 73, and the upper surface of the spraying plate 10 can be in contact with or separated from the mounting rod 74. The first connecting rod 72 is used to adjust and limit the angle of the spraying plate 10, so as to adapt to the placement and spraying needs of belt fish with different body lengths, and facilitate manual swinging of the spraying plate 10 to cooperate with the elastic column 35 to shake off impurities, thereby solving the problems of poor adaptability and complicated cleaning of the fixed spraying plate.

[0030] The spraying assembly 20 includes a connecting block 22 rotationally connected with the mounting rod 74, and a spray head 23 detachably connected to the connecting block 22. Thus, the connecting block 22 and the spray head 23 can be replaced conveniently. The spray head 23 has a spraying conveying pipe 21 in communication with an inlet end of the spray head 23. The spraying conveying pipe 21 is connected with a first pipe body 61 in communication therewith.
