Description

Technical Field

[0001] The invention relates to the technical field of aquatic product processing, in particular to a mussel preservation process and a matching processing device. Background Art

[0002] Shellfish are tender and nutritious. They are rich in lipids, amino acids, active proteins, sugars, trace elements and other nutrients. They have the effects of improving blood lipids and enhancing immunity. In the context of cultivating the sea and fishing and building a blue granary, shellfish can be used as an important source of blue protein for humans and are deeply loved by consumers. Since shellfish live in humid environments such as water or mudflats all year round, they have a short survival time after leaving the water, and it is difficult to circulate and store them freshly. Therefore, in the season when shellfish meat is abundant and plump and concentrated on the market, it is impossible to transport and sell shellfish raw materials at a high value by relying solely on traditional fresh sales methods, and they need to be processed in time. At present, there are few fresh mussels circulating in large quantities across the country, and the product form and quality rate are low. In addition, there are many types, different shapes and sizes, and poor mechanical versatility. The research and development of processing and preservation methods for fresh shellfish is the main problem that must be solved to achieve large-scale circulation of shellfish.

[0003] However, in the prior art, shellfish products such as thick-shelled mussels and oysters are mostly processed at the primary processing stage, lacking processing precision and depth. Some bagged products have low added value, and the products are directly exposed to the air for transportation and sale, making it difficult to ensure that the individual remains completely fresh throughout the shelf life, and the fresh taste will gradually disappear over time. The circulation process is also very likely to cause damage to the shell of shellfish, fishy odor, and death. The decline in the quality of fresh shellfish directly leads to a decrease in its market acceptance and consumer expectations, which is not conducive to the promotion of shellfish products. It also faces severe tests on the preservation and survival effects of mussels and the sale of products, and cannot meet the needs of consumers for fresh mussels. Therefore, it is urgent to propose a mussel preservation process. Summary of the invention

[0004] The purpose of the present invention is to provide a mussel preservation process in view of the above technical problems, which can maintain the high quality of fresh shellfish products for a long time and meet the needs of consumers for fresh mussels.

[0005] To achieve the above object, the present invention provides the following technical solution: a process for keeping mussels fresh, comprising the following steps: (1) Clean the mussels, spread them out and visually inspect and sort them, select mussels of appropriate size as raw materials, and pack them into boxes; (2) Packaging is carried out after controlled atmosphere inflation.

[0006] Preferably, the thick-shelled mussels cultured in Shengsi County, Zhoushan City, Zhejiang Province are used in the above mussel preservation process; thick-shelled mussels products with good growth status, full meat and bright shell color are selected as production materials.

[0007] Preferably, the mussels are sorted based on physical indicators such as shell length, shell width, and weight.

[0008] Furthermore, during sorting, mussels with uniform shell length, shell width and shell height are selected, damaged and dead individuals are removed, and mussels of appropriate size are selected as raw materials. The fatness is tested to ensure that the mussels of this size have thick meat and better taste, which can better meet the market demand for high-quality seafood products.

[0009] As a priority, manual selection is used during sorting to retain high-quality mussels with intact shells, plump meat, and full vitality, and remove mussels with damaged shells, cracks or openings, and empty shells. These unqualified mussels are not suitable for modified atmosphere packaging due to damage, internal corruption, or natural elimination.

[0010] Preferably, the mussels are weighed before packaging, and mussels of acceptable weight are placed in food-grade packaging boxes, while excessive squeezing or stacking is avoided to avoid damage to the mussels.

[0011] Furthermore, food-grade polypropylene packaging boxes or polyethylene packaging boxes are used for packaging.

[0012] Furthermore, the gas conditioning machine is preheated at 150-200°C for 30-50 minutes before the gas conditioning inflation.

[0013] Furthermore, the inflation time is adjusted by adjusting the gas conditioning equipment, and each group of single cycles is set to 2.0~5.0s to ensure that the concentration of key gases filled into the product is ≥60%. Preferably, a sufficient amount of oxygen is injected into each packaging box, and the oxygen used is food-grade pure oxygen or oxygen prepared by a professional oxygen generator. After filling with oxygen, the stability of the gas environment and air pressure in the packaging box can be ensured, and the necessary breathing environment can be provided for the mussel products in the box. At the same time, the invasion of external pollutants can be prevented, the growth of harmful microorganisms can be inhibited, and the collision of mussels in the box during transportation can be avoided, which reduces the stress response of mussels, provides the best fresh-keeping conditions for mussels, and greatly extends the edible period of the product.

[0014] Preferably, polyethylene film is used for packaging.

[0015] Preferably, the packaging temperature is 150-200°C.

[0016] The mussel product obtained by the above mussel preservation process has a shelf life of 15 days, and the survival rate of the mussels is ensured to be 100% within this period.

[0017] Furthermore, the unpackaged raw materials can be stored in an environment of 0-4°C after cleaning and sorting, and the mussel storage density is 2400 mussels / m3. Similarly, the unpackaged mussels can also be kept fresh by temporarily culturing in water, and the water quality parameters of the temporary culturing water are 25-31‰ salinity, dissolved oxygen higher than 3ppm, and pH constant within the range of 7±0.5.

[0018] As a preferred method, in order to maintain the freshness and quality of mussel products from production to consumption, a cold chain circulation method is adopted throughout the process. That is, the temperature is strictly controlled throughout the transportation, storage and sales process to reduce the rate of microbial reproduction and mussel metabolism, thereby extending the survival time and shelf life of the product.

[0019] Furthermore, in the above-mentioned mussel preservation process, the production environment temperature is 10-15°C, and after packaging is completed, the temperature of cold storage, cold chain transport vehicles and product sales cabinets is controlled at 0-10°C, preferably 0-4°C.

In the guiding processing trough box 8, the fresh mussels are processed to ensure the sanitary quality of the product, so that the processed fresh mussels are controlled by the positioning metering discharger 9 according to preset parameters. The amount of material discharged each time ensures that the material is accurately transported to the packaging box 11 on the surface of the horizontal transport guide belt 10.

[0043] according to Figure 1 and Fig. 9As shown, packaging boxes 11 are evenly divided and equidistantly installed on the surface of the transverse transport guide belt 10, and an automatic box cover film filler 12 is installed on the side end of the transverse transport guide belt 10. The side end of the automatic box cover film filler 12 is connected to a box cover film outlet end 13, and an automatic sealing arm structure 14 is installed on the side end of the box cover film outlet end 13. When the packaging boxes 11 are transported by the transverse transport guide belt 10, a certain distance is maintained between each packaging box 11 to ensure the smooth progress of subsequent operations. Then, when the packaging boxes 11 reach the position of the automatic box cover film filler 12, the box cover film will be automatically filled to the top of the packaging box 11, so that the box cover film outlet end 13 outputs the box cover film from the automatic box cover film filler 12 and transports it to the top of the packaging box 11, and then the automatic sealing arm structure 14 makes the box cover film fit tightly to the top of the packaging box 11 to complete the sealing process, and then the heat sealing box structure 158 ensures that the box cover film is tightly combined with the packaging box 11 by using heat sealing.

[0045] The mussel preservation process and working principle of the present invention are as follows: first, mussels with suitable specifications such as shell length, shell width, shell height and good fatness are selected as raw materials, and the processing environment temperature is controlled to be 15°C. The fresh mussels to be cleaned by byssus are placed in the byssus cleaning box 103 through an external conveying structure, so that the cleaning liquid is sprayed from the seawater cleaning box 109 to the surface of the fresh mussels through the spray cleaning plate 108, and the stubborn stains are removed by ultrasonic vibration to improve the cleaning efficiency. Then, the first driving structure 104 and the second driving structure 105 are started to make the first transverse byssus cleaning side roller 1090 and the second vertical byssus cleaning side roller 1091 start to operate, and the first transverse byssus cleaning side roller 1090 and the second vertical byssus cleaning side roller 1091 are staggered. The surface of the fresh mussels is cleaned with byssus, so that a larger cleaning area can be covered, and the cleaning efficiency is improved to remove impurities and attachments such as mud, seaweed, etc. on the surface, to ensure that the surface of the cleaned mussels is smooth and free of dirt, and the color is natural, to ensure the integrity of the subsequent fresh mussels, and then the cleaned fresh mussels are tilted from the outlet of the outlet valve end 106 to the ladder conveyor belt structure 201, and then the weighing and metering structure 206 is in the starting state. When the cleaned fresh mussels are transported upward with the ladder conveyor belt structure 201, the side fence 202 can prevent the material from falling during the transportation process, and simultaneously ensure the approximate weight equality of the fresh mussels at the ladder conveyor belt structure 201, and then the ladder conveyor belt structure 201 is discharged through the discharge guide end 203, and then discharged from the ladder conveyor belt structure 201. The chute delivery end 204 guides the fresh mussels to the surface of the flat plate 406. When the fresh mussels are placed on the flat plate 406, the drive adjustment motor 402 is started, so that the drive adjustment motor 402 provides power, which is transmitted to the guide connecting rod 404 after being decelerated by the reduction gear set 403, so that the guide connecting rod 404 drives the flat plate 406 to form a left and right reciprocating sliding translation operation under the support of the rolling slide structure 405, so that the fresh mussels on the flat plate 406 are evenly spread out during the reciprocating motion, and the fresh mussels are drained of excess water through the drain end 407 on the surface of the flat plate 406, and the steering motor 503 and the electric telescopic lifting column 507 are started in advance, so that the sliding support vertical column 502 slides along the horizontal screw rod linear rail 501 , realize horizontal movement, then the steering motor 503 drives the steering wheel 504 to rotate, realize steering, and make the electric telescopic lifting column 507 adjust the height of the leveling rod 508, so that the leveling rod 508 levels the surface of the material under the drive of the electric telescopic lifting column 507, and use the counting and statistical end 509 to take images for visual inspection and counting, and use the marking cross target rod structure 5090 to mark, and at the same time start the steering drive motor box 602, so that the steering drive motor box 602 drives the multi-axis drive arm structure 603 to turn, so that the pneumatic claw clamp structure 604 is aligned with the material, so that the pneumatic claw clamp structure 604 can grab the material under the drive of the multi-axis drive arm structure 603, and at the same time, with the cooperation of the visual detection sensor, detect the state of the fresh mussels,The thick-shelled mussels are graded according to their shell length, shell width, weight and other physical indicators. In order to ensure the uniformity and high quality of the products, mussels of similar specifications are particularly selected as selected raw materials, so that the fresh mussels can better maintain the product shape and consistency, and the fresh mussels that meet the requirements are grabbed onto the surface of the alternative conveyor belt 7, and a secondary manual visual inspection is performed by the staff at the separate workstations to facilitate a detailed manual selection process, and mussels with damaged shells, cracks or openings, and empty shells are removed. The processed fresh mussels are transmitted through the alternative conveyor belt 7, and unqualified fresh mussels are automatically identified and grabbed by the visual inspection grabbing component 6 and enter the defective material conveying box 17, while the remaining qualified fresh mussels continue to The fresh mussels are transported and finally fall into the guiding and processing trough box 8. In the guiding and processing trough box 8, the fresh mussels are processed to ensure the sanitary quality of the product, so that the processed fresh mussels are controlled by the positioning metering discharger 9 according to the preset parameters to control the amount of material discharged each time, and ensure that the material is accurately transported to the inside of the packaging box 11 on the surface of the transverse transport guide belt 10. The packaging box 11 is a food-grade polyethylene packaging box. When the packaging box 11 is transported by the transverse transport guide belt 10, a certain distance is maintained between each packaging box 11 to ensure the smooth progress of subsequent operations. Then, when the packaging box 11 reaches the position of the automatic box cover film filler 12, the box cover film will be automatically filled to the top of the packaging box 11, so that the box cover film outlet end 13 will remove the box cover film from the automatic The box cover film is output from the box cover film filler 12 and transported to the top of the packaging box 11, so that the automatic sealing arm structure 14 makes the box cover film fit tightly to the top of the packaging box 11 to complete the sealing process. After that, the heat sealing box structure 158 uses heat sealing to ensure that the box cover film is tightly combined with the packaging box 11, and the gas conditioner 150 is started, preheated at 160°C for 30 minutes, and then the motor transmission structure 154 is started, so that the gas conditioner 150 outputs fresh-keeping gas, the main component of which is oxygen, which is transported to the hollow rack 156 through the gas conditioning guide pump pipe 151, and then the motor transmission structure 154 drives the transmission gear 155 to rotate, so that the transmission gear 155 is engaged with the hollow rack 156, and drives the hollow rack 156 to move along the side rail 153, and then the middle After the empty rack 156 moves to the designated position, when the live mussels in the packaging box 11 are heat-sealed by the heat-sealed box structure 158, the gas is injected into the packaging box 11 through the gas injection end 157. The upper gas filling time is 1.1s, the lower gas filling time is 1.0s, and each group of single cycles is 3.0s. At the same time, the pneumatic positioning frame structure 16 can be used to position and fix the packaging box 11 when the packaging box 11 is transported inside the heat-sealed box structure 158. It is convenient for the gas injection end 157 to perform gas injection operations. The polyethylene film is used to complete the packaging at 160°C. After the packaging is completed, the temperature of the cold storage, cold chain transport vehicle and product sales cabinet is controlled at 1~5°C.

[0046] The specific value of the present invention is further illustrated with reference to the following examples.

[0047] Embodiment 1:

[0048] 1. Experimental location: Yimiba Shellfish Industrial Park, No. 180, Houwan Road, Qiguan Village, Gouqi Township, Shengsi County, Zhoushan, Zhejiang; 2. Trial time: July 2023; 3. Experimental design: 500 mussels were taken from the thick-shelled mussel culture group in Gouqi Township, Shengsi County, Zhoushan, Zhejiang Province for a controlled atmosphere survival experiment. The experiment set up a control group and an experimental group, and each group was set up with 6 repeated experiments; Control group: 20 mussels were randomly selected from each group. The surface impurities of the selected thick-shelled mussels were removed by the mussel cleaning component to keep their shells clean. The selected mussels were evenly placed in the packaging box through the specification sorting component, and directly packaged using the gas conditioning component without adding any additional gas, only using the original air in the box. After packaging, they were stored in a cold storage at 0-8℃, and the survival effect of the boxed thick-shelled mussels was checked every 24 hours; Experimental group: 20 mussels were randomly selected from each group, and the surface impurities of the selected thick-shelled mussels were removed by the mussel cleaning component to keep their shells clean. The selected mussels were evenly placed in the packaging box through the specification sorting component. According to the different filled gases, there were three experimental groups. Among them, experimental group 1 added oxygen provided by the oxygen tank; experimental group 2 set the vacuum degree to 0.03MPa and retained 30% air; experimental group 3 added a ternary mixed gas consisting of 30% oxygen, 40% carbon dioxide and 30% nitrogen. After packaging, store in a cold storage at 0-8℃, and check the survival effect of the boxed thick-shelled mussels every 24 hours; The opening status, survival rate and freshness of thick-shelled mussels after cooking were counted on the first and sixth days after production, and all data were expressed as average values. Survival rate = number of surviving mussels in the box / total number of mussels in the box; Survival evaluation criteria: After taking out the mussels from the box, soak or rinse them directly in tap water to observe whether the shells can close. Mussels that cannot close for more than 1 minute are considered dead. The criteria for judging the opening state are as follows: mussels that have not opened are defined as being in a tightly closed state; mussels with an opening angle less than 5° and an opening distance less than 0.5 cm are defined as being in a slightly open state; mussels with an opening angle greater than 5° and less than 10° are defined as being in a medium open state; and mussels with an opening angle greater than 10° and an opening distance greater than 1 cm are defined as being in a large open state. Freshness evaluation criteria: Based on the comprehensive evaluation of the smell when opening the package, the smell during the boiling process, and the smell and taste after cooking, it is divided into three levels: fresh, relatively fresh, and not fresh. The freshness of mussels with a savory taste and surviving individuals is defined as fresh, the freshness of mussels without a savory taste and most of the individuals are dead is defined as not fresh, and the freshness of mussels between the two is defined as relatively fresh; 4. Test results and analysis: It can be clearly seen from the results in Tables 1 and 2 that the survival and preservation effects of the boxed thick-shelled mussel products can be significantly improved with the increase of the oxygen concentration in the added gas. Among them, after adding 30% of the ternary gas, the survival rate of experimental group 3 after 6 days of validity was 50%, and the surviving individuals lost their umami taste after being cooked. The experiment proved that under the same test conditions and storage environment, the high concentration of oxygen used in the present invention is conducive to improving the preservation ability of boxed mussel products.

The selected mussels were evenly placed in the packaging box through the specification sorting component and directly packaged using the controlled atmosphere component. After packaging, three experimental groups were set up according to different storage environments. Among them, experimental group 1 was placed in a 10°C storage environment after packaging; experimental group 2 was placed in an 18°C ​​storage environment after packaging; experimental group 3 was placed in a room temperature 25°C storage environment after packaging. Check the survival effect of the boxed thick-shelled mussels every 24 hours; On the first, third and sixth days after production, the opening status, opening rate, water spitting rate, survival rate and freshness of the boxed thick-shelled mussels after cooking were counted, and all data were expressed as average values; Survival rate = number of surviving mussels in the box / total number of mussels in the box; Opening rate: number of opened mussels in the box / total number of mussels in the box; Water spitting rate: water spitting weight of mussels in the box / total weight of products in the box; Survival evaluation criteria: After taking out the mussels from the box, soak or rinse them directly in tap water to observe whether the shells can close. Mussels that cannot close for more than 1 minute are considered dead. The criteria for judging the opening state are as follows: mussels that have not opened are defined as being in a tightly closed state; mussels with an opening angle less than 5° and an opening distance less than 0.5 cm are defined as being in a slightly open state; mussels with an opening angle greater than 5° and less than 10° are defined as being in a medium open state; and mussels with an opening angle greater than 10° and an opening distance greater than 1 cm are defined as being in a large open state. Freshness evaluation criteria: Based on the comprehensive evaluation of the smell when opening the package, the smell during the boiling process, and the smell and taste after cooking, it is divided into three levels: fresh, relatively fresh, and not fresh. The freshness of mussels with a savory taste and surviving individuals is defined as fresh, the freshness of mussels without a savory taste and most of the individuals are dead is defined as not fresh, and the freshness of mussels between the two is defined as relatively fresh; 4. Test results and analysis: According to the results in Tables 3, 4 and 5, it can be clearly seen that under different storage environments, the survival effect of boxed thick-shelled mussels was significantly affected. In the face of high temperatures in summer, through simulating normal temperature environments and high-temperature transportation, it was found that a large number of mussels died in the 18°C ​​and 25°C environments. The survival status and freshness of the control group and experimental group 1 remained at a high level within the shelf life, indicating that the storage environment of 0-10°C can maintain the best taste and freshness of boxed thick-shelled mussels within the shelf life of the product.

[0051]

[0052] Note: Three days after production, the packaging of experimental group 3 was bloated in the 25℃ environment, and it smelled bad when opened. All mussels died, resulting in the inability to calculate the water spitting rate.

[0053] Note: Four days after production, the mussels in experimental group 2 began to stink, and it was determined that all the mussels were dead, but the packaging did not swell, so the data of experimental groups 2 and 3 could not be counted 6 days after production. Embodiment three:
