Description

Technical Field

[0001] This invention relates to the field of food production and processing technology, and in particular to a production equipment and processing method for freeze-dried sea cucumber seasoned seaweed. Background Technology

[0002] Seaweed, as a snack, concentrates various B vitamins found in laver, especially riboflavin and niacin, and is also rich in vitamins A and E, as well as a small amount of vitamin C. Seaweed contains about 15% minerals, including essential minerals such as potassium, calcium, magnesium, phosphorus, iron, zinc, copper, and manganese, which are crucial for maintaining normal physiological functions. It is particularly rich in selenium and iodine. These minerals help maintain the body's acid-base balance, are beneficial for children's growth and development, and can help slow down aging in the elderly. Seasonings containing functional ingredients such as sea cucumber and collagen can also be added to further enrich the product's health benefits.

[0003] The current seaweed processing mainly involves first spreading, cutting, and baking the raw seaweed into dried laver, and then further baking, seasoning, cutting, and packaging the dried laver. Often, repeated high-temperature baking can destroy some nutrients in sea cucumbers or seaweed, easily causing some nutrients to be lost. The existing seaweed production equipment works independently and lacks linkage between equipment, resulting in increased energy consumption. Summary of the Invention

[0004] To address the issues of nutrient loss, relatively independent production equipment, and increased energy consumption in existing seaweed processing methods, this invention provides a production equipment and processing method for freeze-dried sea cucumber flavored seaweed.

[0005] Specifically, the following technical solutions are included:

[0006] In a first aspect, a production equipment for freeze-dried sea cucumber seasoned seaweed is provided, comprising a washing tank, a crushing box, a marinating box, a cooking box, a forming device, a freeze-drying device, and a packaging machine connected in sequence. The washing tank is connected to the crushing box through a lifting mechanism. The crushing box is located above the washing tank. A rotating shaft is provided inside the crushing box. One end of the rotating shaft is connected to a first drive motor, and the other end of the rotating shaft passes through the bottom of the crushing box and extends into the washing tank.

[0007] Preferably, the lifting mechanism is located on one side inside the cleaning pool.

[0008] Preferably, the marinating box is connected to one side of the crushing box, the cooking box is connected to one side of the marinating box, the forming device is located below the cooking box, the freeze-drying equipment is connected to one side of the forming device, and the packaging machine is connected to one side of the freeze-drying equipment.

[0009] Furthermore, a stirring rod is fixedly connected to one end of the rotating shaft that extends into the cleaning tank, and a shearing component is also provided at the end of the rotating shaft that connects to the first drive motor. The rotating shaft is connected to the lifting mechanism via a transmission shaft.

[0010] In this process, the first drive motor rotates the shaft, which in turn rotates the stirring rod to agitate the algae in the cleaning tank, breaking up and stirring the algae, accelerating the settling of dust and sand particles, and improving cleaning efficiency. The drive shaft then drives the lifting mechanism to scoop up the algae from the cleaning tank and transport it to the crushing box. Simultaneously, the shaft drives the shearing assembly to crush the algae in the crushing box. The shaft also enables linkage between the cleaning tank, crushing box, and lifting mechanism, improving energy utilization and reducing energy consumption. A marinating box is used to season the algae, which is then cooked in a steaming box to reduce the presence of microorganisms. The cooked algae is then supported by a forming device to form the initial algae embryo, which is then freeze-dried using a freeze-drying device to retain more nutrients in the seaweed product. Finally, it is bagged and sealed using a packaging machine.

[0011] Furthermore, the shearing assembly includes a first shearing member and a second shearing member rotatably connected to the rotating shaft; the first shearing member and the second shearing member rotate in opposite directions, a speed-changing assembly is provided between the first shearing member and the rotating shaft, and a direction-changing assembly is provided between the second shearing member and the rotating shaft.

[0012] By adopting the above technical solution, the rotation of the first shearing member is increased by the speed-changing component, and the rotation direction of the second shearing member is changed by the direction-changing component, so that the rotation directions of the first and second shearing members are opposite. A shearing force is formed between the first and second shearing members, which improves the crushing efficiency of the raw algae. By utilizing the pushing force of the second shearing member on the raw algae when it rotates, the raw algae in the crushing box also generate centrifugal force, which can push the raw algae to the outlet of the crushing box.

[0013] Furthermore, the transmission assembly includes a transmission rod disposed on one side of the rotating shaft, with a first gear and a second gear fixedly connected to both ends of the transmission rod respectively; a third gear is disposed on the rotating shaft and is connected to the first gear in a transmission manner; a fourth gear is disposed on the first shearing member and is connected to the second gear in a transmission manner; a sealing cover is provided on the outer periphery of the rotating shaft and the transmission rod; and the transmission rod is rotatably connected to the sealing cover.

[0014] Preferably, the outer diameter of the third gear is larger than that of the first gear, the outer diameter of the second gear is larger than that of the first gear, and the outer diameter of the second gear is larger than that of the fourth gear.

[0015] By adopting the above technical solution, since the outer diameter of the third gear is larger than that of the first gear, the outer diameter of the second gear is larger than that of the first gear, and the outer diameter of the second gear is larger than that of the fourth gear, when the rotating shaft rotates at low speed, the high rotation of the first shearing piece is achieved, which is beneficial to crushing the raw algae and improving the crushing efficiency.

[0016] Furthermore, the reversing assembly includes a first bevel gear fixedly connected to the drive shaft, with a second bevel gear and a third bevel gear respectively drivingly connected to both sides of the first bevel gear; the second bevel gear is fixedly connected to the rotating shaft, and the third bevel gear is fixedly connected to the second shearing member.

[0017] By adopting the above technical solution, the rotation direction of the second shearing member is changed by the cooperation of the first bevel gear, the second bevel gear, and the third bevel gear, so that the rotation direction of the second shearing member is opposite to that of the first shearing member. A shearing force is formed between the first and second shearing members, thereby improving the efficiency of algae crushing.

[0018] Furthermore, the lifting mechanism includes a fixed frame, on which a transmission roller assembly is mounted. The transmission roller assembly is connected to a transmission shaft. A conveyor belt is wound around the transmission roller assembly. One end of the conveyor belt is connected to the washing tank, and the other end of the conveyor belt is connected to the inlet of the crushing box. A partition is mounted on the outer surface of the conveyor belt.

[0019] Preferably, the partition is used to collect the original algae.

[0020] By adopting the above technical solution, the transmission shaft drives the transmission roller group to rotate, thereby driving the transmission belt to rotate and lifting the raw algae upward to the inlet of the crushing box; by setting baffles on the transmission belt, it is convenient to collect the raw algae and improve the collection efficiency.

[0021] Furthermore, the marinating box includes a box body, a roller is installed inside the box body, a guide plate is installed inside the roller, a second drive motor for driving the roller to rotate is installed on the box body, the output end of the second drive motor is connected to one end of the roller, a seasoning box is installed at the inlet of the roller, a control valve is installed at the outlet of the seasoning box, a weighing device is installed below the roller, the control terminal of the control valve is electrically connected to the weighing device, and a refrigeration mechanism is installed below the box body, the refrigeration mechanism is connected to the interior of the box body.

[0022] Preferably, the body of the pickling box is connected to both the crushing box and the cooking box.

[0023] By adopting the above technical solution, the weight of the raw algae in the drum is weighed by a weighing device to determine the weight of the seasoning to be added. The amount of seasoning to be added is controlled by a control valve. At the same time, the second drive motor drives the drum to rotate, and a guide plate is set inside the drum. This facilitates the even mixing of the raw algae and the seasoning, and also makes it easy to remove the raw algae from the drum. By setting a refrigeration mechanism to cool the inside of the chamber, the pickling of the raw algae is kept at a low temperature, which can inhibit the growth and reproduction of microorganisms and ensure the freshness and hygiene of the raw algae.

[0024] Furthermore, the control valve includes a valve body rotatably connected to the outlet of the seasoning box, one end of the valve body is connected to a servo motor, the servo motor is fixedly connected to the housing, and a metering groove is provided on the side wall of the valve body.

[0025] By adopting the above technical solution, the weight of the original algae in the drum is weighed by the weighing device, thereby calculating the amount of seasoning to be added. The valve body is driven to rotate by the servo motor, adding the seasoning in the measuring tank into the drum. By dividing the weight of the seasoning to be added by the weight of the seasoning in the measuring tank, the total number of rotations required by the valve body can be calculated, realizing automatic quantitative addition of seasoning, reducing the difference between each batch of products, and improving work efficiency.

[0026] Furthermore, the forming device includes a frame, on which a conveyor belt is mounted, and a stepper motor for driving the conveyor belt to rotate is mounted on the frame. A material distribution assembly is mounted above the conveyor belt, comprising a material distribution box fixed to the frame. The discharge port of the cooking chamber is connected to the material distribution box. Multiple discharge pipes are mounted at the bottom of the material distribution box, and valves are mounted on the discharge pipes. A sleeve frame is mounted below the discharge pipes. A lifting assembly is mounted between the sleeve frame and the frame. The lifting assembly includes a cylinder fixed to the frame, and a lifting frame is connected to the telescopic end of the cylinder. The lifting frame is connected to the sleeve frame, and multiple guide rods are fixed on the lifting frame. Guide holes that cooperate with the guide rods are provided on the frame. A pressure plate is connected to one side of the lifting frame located on the sleeve frame, and an absorbent sponge is mounted on the pressure plate.

[0027] Preferably, the conveyor belt is provided with a mesh curtain mold, and the output end of the conveyor belt is provided with a collection rack for storing the mesh curtain mold.

[0028] By adopting the above technical solution, the raw algae in the dispensing box is quantitatively added to the mesh curtain mold through the control valve, realizing automated control and ensuring that the weight of each batch of seaweed is consistent. Since the raw algae in the dispensing box is mixed with moisture, the lifting component controls the lifting of the sleeve frame, pressing the sleeve frame onto the mesh curtain mold to prevent the raw algae from scattering. At the same time, the lifting component drives the pressure plate to lift and lower, pressing the raw algae on the mesh curtain mold into seaweed. The mesh curtain mold containing seaweed is collected by the collection rack, which facilitates the subsequent feeding of the mesh curtain mold into the freeze-drying equipment for drying.

[0029] Secondly, a method for processing freeze-dried sea cucumber seasoned seaweed is provided, using the production equipment for freeze-dried sea cucumber seasoned seaweed described in the first aspect, including the following steps:

[0030] S1. Raw material preparation: Select Porphyra stripes algae and sea cucumber as raw materials;

[0031] S2. Cleaning: Soak the raw materials in the water of the cleaning tank to remove sand and impurities from the surface of the raw materials. The raw materials are cleaned by stirring to ensure that the raw materials are clean.

[0032] S3. Cutting: Send the cleaned algae and sea cucumber from step S2 to the crushing box for chopping;

[0033] S4. Seasoning: Mix the chopped raw materials from step S3 with 3‰ of the weight of the seasoning, store in a marinating box, and marinate for 4 hours at 0-4℃, turning once every hour to obtain the marinated raw materials;

[0034] S5. Steaming: The marinated raw materials from step S4 are steamed at high temperature in a steaming chamber to obtain the steamed raw materials;

[0035] S6. Shaping: Place the cooked raw material into the shaping device and divide it into portions of 25g each to obtain the packaged raw material;

[0036] S7. Freeze-drying: The packaged raw materials are transported to a freeze-drying device for freeze-drying to obtain freeze-dried seaweed.

[0037] S8. Packaging: The freeze-dried seaweed is sent to the packaging machine for bagging.

[0038] In step S3, the algae are chopped into 3cm lengths and the sea cucumbers are chopped into 1mm pieces to ensure even distribution of the seasoning.

[0039] In step S4, the weight percentage of the chopped raw material is 95% of the original algae and 5% of the sea cucumber.

[0040] In step S5, the high-temperature cooking temperature is 95±5℃ and the time is 25min.

[0041] In step S7, the freeze-drying process is carried out with a water content of ≤5% by weight, and the temperature of the freeze-drying equipment is controlled below -40℃.

[0042] The beneficial effects of this invention are as follows:

[0043] 1. The linkage between the washing tank, crushing box and lifting mechanism is realized by the rotating shaft, which improves the energy utilization rate and reduces energy consumption; the raw seaweed is seasoned by setting up a pickling box, and the pickled raw seaweed is steamed in the steaming box to reduce the presence of microorganisms and ensure the quality of seaweed; the steamed raw seaweed is supported by the forming device to form the seaweed embryo, and then the seaweed embryo is freeze-dried by the freeze-drying equipment to retain more nutrients in the seaweed.

[0044] 2. The weight of the original algae in the drum is weighed by the weighing device to calculate the amount of seasoning to be added. The valve body is driven to rotate by the servo motor to add the seasoning in the measuring tank into the drum. By dividing the weight of the seasoning to be added by the weight of the seasoning in the measuring tank, the total number of rotations of the valve body can be calculated, realizing automatic quantitative addition of seasoning, reducing the difference between each batch of products and improving work efficiency.

A rotating shaft 9 is installed inside the crushing box 2. One end of the rotating shaft 9 is connected to a first drive motor 10, and the other end of the rotating shaft 9 passes through the bottom of the crushing box 2 and extends into the washing tank 1. A stirring rod 94 is fixedly connected to the end of the rotating shaft 9 extending into the washing tank 1. A shearing component 91 is also provided at the end of the rotating shaft 9 connected to the first drive motor 10.

[0060] In use, the first drive motor 10 drives the rotating shaft 9 to rotate, which in turn drives the stirring rod 94 to rotate, stirring the raw algae in the cleaning tank 1, breaking up and stirring the raw algae, accelerating the settling of dust and sand particles in the raw algae, and improving the cleaning efficiency; the transmission shaft 95 drives the lifting mechanism 8 to scoop up the raw algae in the cleaning tank 1 and transport it to the crushing box 2. At the same time, the rotating shaft 9 drives the rotation of the shearing component 91 to crush the raw algae in the crushing box 2; the rotating shaft 9 realizes the linkage between the cleaning tank 1, the crushing box 2 and the lifting mechanism 8, improving the energy utilization rate and reducing energy consumption; the raw algae is seasoned by setting up the pickling box 3, and the pickled raw algae is steamed in the cooking box 4 to reduce the presence of microorganisms. The steamed raw algae is supported by the forming device 5 and then freeze-dried by the freeze-drying equipment 6 to retain more nutrients in the seaweed product. Finally, it is bagged and sealed by the packaging machine 7.

[0062] In use, the rotation of the first shearing member 911 is increased by the speed-changing component 92, and the rotation direction of the second shearing member 912 is changed by the direction-changing component 93, so that the rotation directions of the first shearing member 911 and the second shearing member 912 are opposite. A shearing force is formed between the first shearing member 911 and the second shearing member 912, which improves the crushing efficiency of the raw algae. Utilizing the pushing force on the raw algae when the second shearing member 912 rotates, the raw algae in the crushing box 2 also generate centrifugal force, which can push the raw algae to the outlet of the crushing box 2.

[0063] The transmission assembly 92 includes a transmission rod 921 disposed on one side of the rotating shaft 9, with a first gear 922 and a second gear 923 fixedly connected to both ends of the transmission rod 921, respectively.

[0072] In use, the weight of the original algae in the drum 32 is weighed by the weighing device 34 to calculate the amount of seasoning to be added. The servo motor 362 drives the valve body 361 to rotate, adding the seasoning in the metering tank 363 into the drum 32. By dividing the weight of the seasoning to be added by the weight of the seasoning in the metering tank 363, the total number of rotations required by the valve body 361 can be calculated, realizing automatic quantitative addition of seasoning, reducing the difference between each batch of products and improving work efficiency.

[0074] The raw algae in the dispensing box 541 is quantitatively added to the mesh curtain mold by the control valve 36, realizing automated control and ensuring that the weight of each batch of seaweed is consistent. Since the raw algae in the dispensing box 541 is mixed with moisture, the lifting component controls the lifting of the frame 542 to press the frame 542 onto the mesh curtain mold, preventing the raw algae from scattering. At the same time, the lifting component drives the pressure plate 548 to lift and lower, pressing the raw algae on the mesh curtain mold into seaweed. The mesh curtain mold containing seaweed is collected by the collection rack, which facilitates the subsequent feeding of the mesh curtain mold into the freeze-drying equipment 6 for drying.
