Description

Technical Field

[0001] The invention relates to the field of aquatic product processing equipment, in particular to a device for peeling thick-shelled mussel columns with water jets at low temperature. Background Art

[0002] Thick-shelled mussels play an important role in the food processing industry due to their rich nutritional value and wide market demand. However, it is difficult to peel off the connection between the scallop and the shell during processing, especially under low-temperature cold chain conditions. Traditional processing methods have major technical bottlenecks in terms of efficiency and product quality.

[0003] In current processing, manual operation is still the main way to peel thick-shelled mussels. Workers use manual tools to separate the mussels from the shells. Another common method is to use mechanical blades to cut the mussels. Blade cutting can easily directly damage the mussel meat, reducing the integrity of the product.

[0004] For the existing devices for peeling thick-shelled mussel posts, firstly, manual peeling is difficult to meet the needs of large-scale assembly line production and has low efficiency. Although mechanical cutting has replaced manual operation to a certain extent, its accuracy is insufficient and it cannot accurately align with the connection between the post and the shell. The damage rate is high and product quality is difficult to guarantee. Secondly, with the popularization of cold chain processing, the adaptability of traditional peeling equipment in low-temperature environments has become a key bottleneck. Problems such as water freezing, equipment embrittlement and insufficient peeling force in low-temperature environments have seriously restricted the practical application of the equipment. Finally, the use of water jets to peel the post will generate a large amount of wastewater, and the wastewater treatment lacks an effective recycling design, which not only wastes resources but also pollutes the environment.

[0017] Analysis module: It analyzes the data collected in the central control system through the data processing unit;

[0018] Driving module: It drives the displacement motor, adjustment motor and resistance heating wire through the analyzed information.

[0019] The present invention also provides a method for using a device for peeling thick-shelled mussel slugs with a water jet at low temperature. According to a device for peeling thick-shelled mussel slugs with a water jet at low temperature, the method comprises the following steps:

[0020] S1, slide the placement plate out along the slide rail 1, pull the fixing clip outward, at this time the fixing spring in the fixing block is stretched, place the thick-shelled mussel on the curved placement block, then release the fixing clip, fix the thick-shelled mussel by using the elasticity of the fixing spring, and then push the placement plate into the operating table through the slide rail 1 again;

[0021] S2. During the peeling process of thick-shelled mussels, the cooling equipment on the installation table cools down the operating table to ensure the fresh taste of the thick-shelled mussels. During the peeling process, the high-pressure water pump pumps out the water in the water tank, and the water pressurized by the high-pressure water pump is transported to the peeling nozzle through the water pipe and the connecting pipe. The water sprayed by the peeling nozzle is aimed at the connection between the mussel column and the thick-shelled mussel so that the mussel column can fall off;

[0022] During the peeling process, the visual sensor captures the position between the sprayed water flow and the shell pillar. When the nozzle position needs to be adjusted, the central control system starts the adjustment motor, which rotates gear 2. Through the meshing relationship between gear 2 and gear 1, gear 1 rotates accordingly. Under the connection of the connecting rod and the fixed frame, the angle of the peeling nozzle changes, so that the water flow sprayed by the peeling nozzle is aimed at the shell pillar at the best angle, making it easier to peel the shell pillar.

[0023] When the visual sensor detects that the peeling of a mussel column is completed, the displacement motor starts to rotate the pulley, and the transmission belt moves accordingly, and is connected through the connecting block to move the mounting block. When the mounting block moves, the slider on the mounting block moves along the second slide rail to aim the peeling nozzle at another thick-shelled mussel;

[0024] S3. During the process of the device continuously peeling the shell pillars, the water temperature sensor constantly detects the water temperature in the water pipe. When the water temperature is lower than the specified value, the resistance heating wire in the antifreeze pipe is energized. The energized resistance heating wire heats up and heats the water in the water pipe. When the temperature reaches a certain value, the resistance heating wire is disconnected.

[0025] S4. During the process of water flow peeling off the scallops, the wastewater enters the filter box through the collection tank and the connected water pipe. The shell fragments and other substances in the wastewater are filtered through the stainless steel filter, polyester screen and activated carbon filter in turn and remain in the filter box. The filtered wastewater then enters the recovery box, and then the ultraviolet sterilization lamp is started to sterilize the wastewater. The treated wastewater is transported back to the water tank through the circulating water pump.

[0026] The present invention provides a device for peeling thick-shelled mussels with water jets at low temperature. It has the following beneficial effects:

[0027] 1. The present invention drives the stripping nozzle by a high-pressure water pump to aim at the connection between the clam column and the shell for high-pressure water jet stripping. At the same time, it combines with a visual sensor to adjust the angle and position of the nozzle in real time, thereby achieving the technical effects of high-precision stripping and high-efficiency assembly line operation. Compared with the low efficiency and high shell meat damage rate of manual stripping or mechanical cutting in the prior art, it solves the problems of incomplete stripping, low efficiency and unstable product quality, and is more suitable for the needs of industrial assembly line production.

[0028] 2. The present invention isolates the external low-temperature environment through the insulation layer of the antifreeze pipe, detects the water temperature in the pipe through the water temperature sensor, and dynamically heats the water flow in combination with the resistance heating wire to ensure that the water flow in the water pipe remains liquid in the cold chain environment, achieving the technical effect of stable operation of equipment and uninterrupted water jet stripping operation in the cold chain environment. Compared with the prior art that water flow is easy to freeze in a low-temperature environment, the shortcomings of obstructed work and limited stripping efficiency in a low-temperature environment are solved, and the applicability and operational stability of the device are significantly improved.

[0029] 3. The present invention achieves the technical effect of saving water resources, reducing operating costs and environmentally friendly processing by multi-stage filtration and sterilization treatment through collection tanks, filter components (stainless steel filter, polyester screen, activated carbon filter) and ultraviolet sterilization lamps, so that waste water can be recycled, and the treated water is transported back to the water tank through a circulating water pump.

[0063] Please see attached Figure 1 -Attached Fig. 9The present invention also provides a method for using a device for peeling thick-shelled mussels by water jet at low temperature, comprising the following steps:

[0064] S1, slide the placement plate 3 out along the slide rail 2, pull the fixing clip 403 outward, at this time the fixing spring 404 in the fixing block 401 is stretched, and the thick-shelled mussel is placed on the curved placement block 402, then release the fixing clip 403, and fix the thick-shelled mussel by using the elasticity of the fixing spring 404, and then push the placement plate 3 into the operating table 1 again through the slide rail 2;

[0065] S2. During the peeling process of thick-shelled mussels, the cooling device 14 on the mounting platform 5 cools down the operating platform 1 to ensure the fresh taste of the thick-shelled mussels. During the peeling process, the high-pressure water pump 602 pumps out the water in the water tank 601. The water pressurized by the high-pressure water pump 602 is transported to the peeling nozzle 605 through the water pipe 603 and the connecting pipe 604. The water sprayed by the peeling nozzle 605 is aimed at the connection between the mussel column and the thick-shelled mussel so that the mussel column can fall off.

[0066] During the peeling process, the visual sensor 13 captures the position between the sprayed water flow and the shell pillar. When the nozzle position needs to be adjusted, the central control system starts the adjustment motor 1105, and the adjustment motor 1105 rotates the gear 2 1104. Through the meshing relationship between the gear 2 1104 and the gear 1 1103, the gear 1 1103 rotates accordingly.

When the mounting block 10 moves, the slider 906 on the mounting block 10 moves along the second slide rail 905, so that the peeling nozzle 605 is aimed at another thick-shelled mussel;

[0068] S3. During the process of continuously peeling the shellfish, the water temperature sensor 8 constantly detects the water temperature in the water pipe 603. When the water temperature is lower than a specified value, the resistance heating wire 703 in the antifreeze pipe 701 is energized. The energized resistance heating wire 703 generates heat to heat the water in the water pipe 603. When the temperature reaches a certain value, the resistance heating wire 703 is disconnected.

[0069] S4. During the process of peeling the scallops with water flow, the wastewater enters the filter box 1202 through the collection tank 1201 and the connected water pipe. The shell fragments and other substances in the wastewater are filtered through the stainless steel filter 1205, the polyester screen 1206, and the activated carbon filter 1207 in turn and remain in the filter box 1202.

10. A method for using a device for peeling thick-shelled mussels with a water jet at low temperature, according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1, slide the placement plate 3 out along the slide rail 1 (2), pull the fixing clamp (403) outward, and then the fixing spring (404) in the fixing block (401) is stretched, and the thick-shelled mussel is placed on the curved placement block (402), then release the fixing clamp (403), and fix the thick-shelled mussel by using the elasticity of the fixing spring (404), and then push the placement plate (3) into the operating table (1) again through the slide rail 1 (2); S2. During the process of peeling the thick-shelled mussel slug, the cooling device (14) on the mounting platform (5) cools down the temperature inside the operating platform (1) to ensure the fresh taste of the thick-shelled mussel. During the peeling, the high-pressure water pump (602) pumps out the water in the water tank (601). The water pressurized by the high-pressure water pump (602) is transported to the peeling nozzle (605) through the water pipe (603) and the connecting pipe (604). The water sprayed by the peeling nozzle (605) is aimed at the connection between the slug and the thick-shelled mussel so that the slug can be peeled off. During the peeling process, the visual sensor (13) captures the position between the sprayed water flow and the shell pillar. When the nozzle position needs to be adjusted, the central control system starts the adjustment motor (1105), and the adjustment motor (1105) rotates the gear 2 (1104). Through the meshing relationship between the gear 2 (1104) and the gear 1 (1103), the gear 1 (1103) rotates accordingly. Under the connection of the connecting rod (1102) and the fixed frame (1101), the angle of the peeling nozzle (605) changes, so that the water flow sprayed by the peeling nozzle (605) is aimed at the shell pillar at the best angle, making the shell pillar easier to peel; When the visual sensor (13) detects that the peeling of a mussel column is completed, the displacement motor (901) is started, causing the pulley (902) to rotate, and the transmission belt (903) moves accordingly, and is connected through the connecting block (904), so that the mounting block (10) moves. When the mounting block (10) moves, the slider (906) on the mounting block (10) moves along the second slide rail (905), so that the peeling nozzle (605) is aimed at another thick-shelled mussel; S3, during the process of the device continuously peeling the shellfish pillars, the water temperature sensor (8) constantly detects the water temperature in the water pipe (603). When the water temperature is lower than a specified value, the resistance heating wire (703) in the antifreeze pipe (701) is energized. The energized resistance heating wire (703) generates heat to heat the water in the water pipe (603). When the water temperature reaches a certain value, the resistance heating wire (703) is disconnected. S4. During the process of water flow peeling off the scallops, the wastewater enters the filter box (1202) through the collection tank (1201) and the connected water pipe. The shell fragments and other substances in the wastewater are filtered through the stainless steel filter (1205), the polyester screen (1206), and the activated carbon filter (1207) in turn and remain in the filter box (1202). The filtered wastewater then enters the recovery box (1203), and then the ultraviolet sterilization lamp (1208) is started to sterilize the wastewater. The treated wastewater is transported by the circulating water pump (1209) and returned to the water tank (601).
