Description

Technical Field

[0001] This utility model relates to the field of sea cucumber processing technology, and in particular to a dewatering device for sea cucumber processing. Background Technology

[0002] Sea cucumber, a precious seafood product with both high nutritional and economic value, occupies an important position in the marine food industry. With the increasing demand from consumers for high-quality sea cucumber products, large-scale and refined processing of sea cucumber has become the core direction of industry development. Throughout the entire sea cucumber processing process, from live harvesting, evisceration, boiling and salting, removing the sand mouth, washing and desalting to subsequent drying, the draining stage is always a key process affecting product quality, processing efficiency, and production costs. Its core objective is to quickly, thoroughly, and without damage remove excess moisture adhering to the surface and internal crevices of the sea cucumber, laying the foundation for subsequent processing steps.

[0003] Currently, the mainstream draining methods in the sea cucumber processing industry are still mainly traditional processes, including natural sun-drying, manual wiping, and simple mesh screen filtration for drainage. Natural sun-drying relies heavily on natural environmental conditions and is greatly affected by factors such as sunlight, wind, temperature, and humidity. Not only is the drainage efficiency low, but sea cucumbers exposed to air for extended periods are susceptible to dust and microbial contamination. Furthermore, high temperatures or strong sunlight can cause the loss of active nutrients, severely impacting product quality stability. Manual wiping can shorten the drying time to some extent, but it requires significant labor costs, and the precise control of manual force can easily damage the sea cucumber's skin and deform its shape. Especially for batch processing, its efficiency and consistency cannot meet the demands of industrial production. Simple mesh screen drainage relies on gravity to allow water to drip naturally, eliminating the need for continuous manual operation. However, the drainage cycle is long, and it only removes surface-attached free water, failing to effectively remove residual water from the internal cavities or folds of the sea cucumber. This significantly increases energy consumption in subsequent drying stages, prolongs the processing cycle, and the residual water can also cause localized spoilage during later processing, reducing the finished product's pass rate.

[0004] As the sea cucumber processing industry transforms towards automation and intelligence, the limitations of traditional dewatering methods are becoming increasingly apparent, creating an urgent need for efficient, stable, and low-loss dewatering solutions. On the one hand, existing dewatering equipment, which simply uses vibrating screens or blowing devices, often suffers from incomplete moisture removal (e.g., insufficient vibration intensity prevents internal moisture from being discharged, or fails to effectively remove the hidden moisture in sea cucumbers). On the other hand, the irregular shape of sea cucumbers (e.g., body wall folds, differences between the head and tail) makes it difficult for conventional dewatering equipment to achieve comprehensive, thorough moisture removal, and some residual moisture can still negatively impact the quality of subsequent processing.

[0020] Example 1 like Figure 1 As shown: A dewatering device for sea cucumber processing includes a rubber belt conveyor 1, a spiral dewatering mechanism 12, and a mesh belt conveyor 22 arranged in sequence. The sea cucumbers are fed at the first end of the rubber belt conveyor 1, undergo primary strong air blowing dewatering through the rubber belt conveyor 1, then enter the spiral dewatering mechanism 12 for dewatering along the spiral path, and finally enter the mesh belt conveyor 22 for secondary weak air blowing dewatering.

[0021] The rubber belt conveyor 1 is equipped with a housing 2 on the outside, and a frame 3 for support is provided below the housing 2.

[0022] The housing 2 is equipped with a feeding hopper 4. The discharge port of the feeding hopper 4 is located above the head of the rubber belt conveyor 1. The side wall of the feeding hopper 4 is inclined so that the sea cucumbers can fall onto the side wall and slide into the rubber belt conveyor 1 after feeding, instead of falling directly onto the rubber belt conveyor 1, which effectively avoids the sea cucumbers falling and hitting the conveyor belt and causing damage.

[0023] The outer wall of the housing 2 near the spiral drainage mechanism 12 has a through hole 5. The rubber belt conveyor 1 is installed inside the housing 2 and its end is located in the through hole 5.

[0024] The rubber belt conveyor 1 consists of an annular rubber conveyor belt and drive rollers at both ends. The drive rollers are connected to the motors used for driving. The rubber conveyor belt of the rubber belt conveyor 1 has through holes. A water receiving tray 6 is provided in the middle of the annular rubber conveyor belt of the rubber belt conveyor 1. The water receiving tray 6 is installed inside the housing 2. The bottom of the water receiving tray 6 is inclined. A drain outlet is provided at the lowest point of the water receiving tray 6. The drain outlet is connected to a water collection tank 8 through a drain pipe 7. The water collection tank 8 is installed on the frame 3.

[0025] In this embodiment, the through hole is a cone shape with a large diameter opening at the top and a small diameter opening at the bottom. When water enters the cone-shaped through hole, its surface tension resistance is smaller, and water can easily pass through.

[0026] A strong wind mechanism for primary air blowing is provided above the rubber belt conveyor 1. The strong wind mechanism includes a strong wind nozzle 9 installed above the rubber belt conveyor 1. The strong wind nozzle 9 is connected to a strong wind fan 11 through a strong wind duct 10.

[0027] In this embodiment, the strong wind fan 11 is a centrifugal fan, and the strong wind nozzle 9 is a fan-shaped nozzle. The air outlet of the fan-shaped nozzle is a flat, wide-angle fan-shaped airflow. The fan-shaped airflow can cover half or even the entire circumference of the sea cucumber at one time. Without the need to frequently adjust the nozzle angle, the airflow can be evenly swept across the sides and abdomen of the sea cucumber, avoiding the dead corner problem of the round nozzle drying out some areas and not reaching the sides. The planar diffusion performance of the fan-shaped airflow allows the airflow to penetrate into the folds and gaps, while gently wrapping the protrusions. It will not skip the gaps and only blow on the protruding parts like the strong concentrated airflow of the round nozzle, nor will it cause moisture to stagnate in the gaps due to the dispersion of the airflow.

[0028] The spiral draining mechanism 12 consists of an outer shell 13 and an inner spiral guide plate. The outer shell 13 is flared, wider at the top and narrower at the bottom. A support frame is provided at the bottom of the outer shell 13. The spiral guide plate is sandwiched between an upper draining plate 14 and a lower support plate 15. Draining holes 16 are provided on the draining plate 14. The outer shell 13 and the spiral guide plate form a spiral cavity 17. A water guiding channel 18 is located between the draining plate 14 and the support plate 15. The water guiding channel 18 is connected to a water collection tank 8 through a water guiding pipe 19.

[0029] The upper feed inlet of the spiral cavity 17 is connected to the end of the rubber belt conveyor 1 via the guide plate 20. The guide plate 20 is gradually widened towards the feed inlet of the spiral cavity 17. The size of the port of the guide plate 20 near the rubber belt conveyor 1 is larger than the length of the sea cucumber. The lower discharge port of the spiral cavity 17 is connected to the head of the mesh belt conveyor 22 via the material-forming plate 21. The material-forming plate 21 is gradually narrowed towards the head of the mesh belt conveyor 22. The size of the port of the material-forming plate 21 near the mesh belt conveyor 22 is adapted to the width of the sea cucumber. The sea cucumbers conveyed from the material-forming plate 21 are in a vertical position. The guide plate 20 and the material-forming plate 21 are inclined.

[0030] The mesh belt conveyor 22 consists of an annular mesh belt and drive rollers at both ends. The drive rollers are connected to motors for driving. The mesh belt reduces the contact area with the sea cucumbers and increases the exposed area of ​​the sea cucumbers. The mesh belt conveyor 22 is equipped with a weak wind mechanism for secondary air blowing. The weak wind mechanism includes a sleeve 23 set outside the working section of the mesh belt conveyor 22. The sleeve 23 is mounted on the base of the mesh belt conveyor 22. Inside the sleeve 23, there are multiple sets of weak wind nozzles 26 arranged in a circular pattern and connected to a weak wind fan through weak wind ducts 24. Each set of weak wind nozzles 26 is evenly arranged along the length of the mesh belt conveyor 22 and the air outlet of the weak wind nozzles 26 faces the working section of the mesh belt conveyor 22. The weak wind fan is mounted on the frame 3.

[0031] In this embodiment, the weak wind fan is an axial flow fan, and the weak wind nozzle 26 is an air knife type nozzle. The air knife type nozzle outputs a weak wind parallel to the length direction of the sea cucumber. Its function is to achieve the dual goals of fine water removal and protection of sea cucumber quality on the basis of primary air blowing, avoiding physical damage or excessive drying of sea cucumber caused by strong wind, while removing hidden moisture in the sea cucumber crevices, improving the uniformity of moisture removal and the final product appearance.

[0032] The core feature of the air knife-type nozzle is that it outputs a linear, uniform, and low-turbulence thin air curtain. In weak wind conditions, the air curtain can better conform to the irregular surface of the sea cucumber, accurately covering the tiny areas not reached by the primary airflow, smoothly pushing away residual moisture and preventing moisture from lingering in the gaps. Weak wind is prone to diffusion and has a limited coverage area. The long strip-shaped air curtain of the air knife can be matched with the conveying direction of the sea cucumber. Multiple air knife-type nozzles with full coverage design achieve surface coverage, ensuring that the front, sides, and even the gaps of the spines of the sea cucumber can be blown evenly, reducing the difference between localized excessive moisture or dryness.

[0033] Both the high-speed fan 11 and the low-speed fan have filter mechanisms 25 installed at their air inlets. Filter mechanisms 25 include a pre-filter (plate type), a medium-efficiency bag filter, a high-efficiency fiberglass paper filter, and an activated carbon filter. The combination of filter mechanisms 25 is a common method with various combinations, which will not be elaborated upon here. The function of the filter mechanisms 25 is to intercept dust, particles, lint, and other impurities in the air, preventing these impurities from adhering to the surface of the sea cucumber with the airflow, affecting its quality, or entering the fan interior and causing wear and blockage of components.

[0034] In this embodiment, the drive rollers of the rubber belt conveyor 1 and the mesh belt conveyor 22 are made of stainless steel 304, and the motors are stepper motors. The rubber belt conveyor 1 and the mesh belt conveyor 22 are common equipment, and the rest of the structure will not be described in detail.

[0035] Work process: 1. Feeding control: After being cleaned, the sea cucumbers are fed into the feeding hopper 4 by manual labor or upstream equipment. The sea cucumbers slide down the side wall to the beginning of the rubber conveyor belt of the rubber belt conveyor 1, and the rubber conveyor belt is conveyed forward under the drive of a stepper motor.

[0036] 2. Strong wind dewatering: When the sea cucumber enters the shell 2, the fan-shaped air nozzles above are activated at the same time, outputting a flat wide-angle airflow. The airflow sweeps across the surface of the sea cucumber in one go, blowing away more than 80% of the free water on the surface.

[0037] 3. Moisture collection: The water blown away and the water dripping from the sea cucumber itself fall into the water receiving tray 6 below through the conical holes on the conveyor belt. The inclination of the bottom of the water receiving tray 6 allows the water to flow naturally to the lowest drain outlet, and then into the water collection tank 8 through the drain pipe 7, so as to realize the centralized recycling of wastewater.

[0038] 4. Material guiding and transition: After the initial dewatering, the sea cucumbers enter the gradually expanding guide plate 20 along the end of the conveyor belt and slide into the spiral cavity 17 of the spiral dewatering mechanism 12 along the inclined guide plate 20.

[0039] 5. Spiral centrifugal dehydration: Under the guidance of the spiral guide plate, the sea cucumber moves slowly from top to bottom along the spiral path. During the process, under the dual action of gravity and centrifugal force, the residual water on the surface of the sea cucumber first seeps into the water guiding channel 18 through the round holes of the drain plate 14; secondly, the hidden water in the internal cavity and fold gaps of the sea cucumber is squeezed out during the spiral turning process, and also enters the water guiding channel 18 through the drain hole 16, and finally is discharged into the water collection tank 8 through the water guiding pipe 19.

[0040] 6. Material conveying: After deep draining, the sea cucumbers are discharged from the lower outlet of the spiral cavity 17, and are arranged into a vertical position by the tapered material plate 21. They are then evenly conveyed to the head of the mesh belt conveyor 22 to avoid the sea cucumbers from piling up and affecting the subsequent weak wind effect.

[0041] 7. Mesh belt conveyor and weak air dewatering: The sea cucumber is conveyed forward on the mesh belt conveyor 22 and enters the sleeve 23. The blade-type air nozzle is activated to output a linear thin air curtain. The air curtain fits the irregular surface of the sea cucumber and accurately covers the tiny gaps that the initial strong air does not reach. The weak air avoids physical damage to the sea cucumber skin and at the same time smoothly pushes away the residual water, ensuring that the water removal rate reaches more than 95%.

[0042] 8. Finished product output: The sea cucumbers that have undergone fine draining are discharged from the end of the mesh conveyor belt 22 and directly enter the subsequent drying process without secondary processing.

[0043] This embodiment constructs a three-stage synergistic drainage system consisting of primary strong wind, spiral centrifugal force, and secondary weak wind. Through structural optimization and functional coordination of each mechanism, it solves the problems of incomplete surface water removal and difficulty in removing hidden moisture in traditional single drainage methods, greatly improving drainage efficiency. The inclined sidewall of the feed hopper 4, the conical through hole, and the wind knife-type weak wind nozzle prevent the sea cucumber from being damaged or deformed by impact or strong wind during transportation and drainage, effectively improving the finished product qualification rate and achieving efficient and damage-free drainage of sea cucumber.

[0044] Example 2 like Figure 2 As shown, the difference between this embodiment and embodiment 1 is that a negative pressure water absorption mechanism is added in this embodiment.

[0045] The negative pressure water suction mechanism includes a vacuum pump 27. A negative pressure connector that communicates with the water guide channel 18 is installed on the outer casing 13. The negative pressure connector is connected to the vacuum pump 27 through a negative pressure pipe 28. A gas-liquid separator 29 is provided on the negative pressure pipe 28. The vacuum pump 27 and the gas-liquid separator 29 are installed on the frame 3.

[0046] To further improve the negative pressure water absorption effect, flexible baffles 30 are provided at the connection between the spiral cavity 17 and the guide plate 20, and at the connection between the spiral cavity 17 and the material plate 21, which can ensure the airtightness of the spiral cavity 17.

[0047] Working principle: 1. Negative pressure environment construction: After starting the vacuum pump 27, the water guide channel 18 of the spiral dewatering mechanism 12 is evacuated through the negative pressure pipe 28 and the negative pressure connector, so that a negative pressure environment is formed in the water guide channel 18; at the same time, the flexible silicone curtain 30 at the connection between the spiral cavity 17 and the guide plate 20 and the material plate 21 is tightly attached to ensure the airtightness of the spiral cavity 17 and prevent outside air from entering and destroying the negative pressure.

[0048] 2. Enhanced water extraction: Under negative pressure, the hidden water in the internal cavity and folds of the sea cucumber is drawn out and accelerates its entry into the water channel 18 through the round holes of the drain plate 14; at the same time, the water in the water channel 18 flows quickly to the gas-liquid separator 29 under the negative pressure, avoiding secondary adsorption caused by water retention.

[0049] 3. Gas-liquid separation and drainage: After water and a small amount of air enter the gas-liquid separator 29, the air is discharged by the vacuum pump 27, and the water settles in the separator. When the water level reaches the set value, the automatic drain valve opens and drains the water into the water collection tank 8, realizing the continuous operation of the negative pressure system.

[0050] This embodiment uses a negative pressure water absorption mechanism to further remove moisture from the inside of the sea cucumber, shortening the draining time and enhancing the draining effect.

[0051] Example 3 like Figure 3 As shown, the difference between this embodiment and embodiment 2 is that a guide hopper 31 is added between the guide plate 20 and the feed inlet of the spiral cavity 17. A circular cavity is provided at the top of the guide hopper 31. A cross-shaped receiving plate 32 is rotatably installed in the circular cavity. In order to further improve the airtightness, multiple receiving plates 32 can be added evenly. The receiving plate 32 has a very small gap with the inner wall of the circular cavity, which can ensure that the receiving plate 32 can rotate freely and improve the airtightness of the spiral cavity 17.

[0052] Working principle 1. Dispersed feeding: The sea cucumbers sliding down from the guide plate 20 first enter the circular chamber of the guide hopper 31. The sea cucumbers fall on one of the receiving rotating plates 32, which drives the receiving rotating plates 32 in the chamber to rotate, and pushes the stacked sea cucumbers one by one to the lower conical discharge port, avoiding congestion caused by multiple sea cucumbers entering the spiral chamber 17 at the same time.

[0053] 2. Enhanced airtightness: The gap between the receiving plate 32 and the inner wall of the circular cavity is small, and a dynamic seal is maintained throughout the rotation process, further reducing the entry of outside air into the spiral cavity 17 and ensuring a stable negative pressure environment.

[0054] 3. Buffer protection: The rotation of the receiving plate 32 prevents the sea cucumber from being violently impacted by the plate, while evenly distributing the sea cucumber into the spiral cavity 17, ensuring that each sea cucumber can fully contact the spiral path and improving the uniformity of drainage.

[0055] This embodiment enhances the airtightness of the spiral cavity 17, reduces the congestion rate of sea cucumber feeding, avoids damage caused by squeezing of sea cucumbers during feeding, and improves the quality of the finished product.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
