Description

Technical Field

[0001] This invention relates to the field of carrageenan technology, specifically to an automated production line for carrageenan processing. Background Technology

[0002] Carrageenan is a natural water-soluble polysaccharide extracted from red algae. As a common food additive and industrial raw material, it has good gelling, thickening, emulsifying stability and film-forming properties. During processing, products of different purities and grades can be obtained through raw material pretreatment, extraction and purification, drying and pulverization. In the food industry, it is widely used in dairy products, meat products, jellies, beverages and other products, where it can thicken, solidify and stabilize the system, improving the taste and shelf life of the products. At the same time, due to its biocompatibility and safety, carrageenan also has important applications in the pharmaceutical, daily chemical and textile fields, such as drug carriers, cosmetic thickeners and printing and dyeing auxiliaries. It is an important industrial material with both natural properties and multiple functions. Traditional carrageenan processing technology has poor adaptability. Most production lines can only adapt to a single type of raw material or a single model of product. When faced with the production needs of raw materials in different states or different models of carrageenan, manual adjustments are required, resulting in low switching efficiency and easy process connection problems. It is impossible to quickly respond to the diverse product demands of the market. Furthermore, the rehydration operation of raw materials in the traditional carrageenan processing field is prone to problems such as unbalanced rehydration ratio and insufficient mixing, resulting in uneven softening of raw materials. Some raw materials are difficult to break due to insufficient rehydration, while some raw materials lose effective components due to excessive rehydration. This not only affects the efficiency of subsequent processing but also reduces the utilization rate of raw materials. The cleaning operation mostly adopts a single cleaning method, which is difficult to achieve efficient removal of both large and fine impurities. It is easy to have impurity residue problems, which in turn affect the purity and quality stability of subsequent products. Summary of the Invention

[0011] Compared with the prior art, the beneficial effects of the present invention are: 1. A conveyor quantitatively transports dried red algae material into the water tank. The first electric telescopic rod shortens, driving the first telescopic frame to move downwards along the inside of the short cylindrical slot seat. The first telescopic frame, in conjunction with the first mounting frame, drives the pressure plate, causing the pressure plate to move downwards inside the water tank. The dried material inside the water tank is fully immersed in water. The first electric telescopic rod extends and retracts, driving the pressure plate with the cooperation of the first telescopic frame and the first mounting frame, thus agitating and stirring the dried material and water. After stirring and soaking, the first electric telescopic rod resets, driving the pressure plate to move out of the water tank. The second electric telescopic rod drives the second telescopic frame to move upwards along the inside of the long cylindrical slot seat, causing the second mounting frame to move downwards. With the assistance of the second telescopic frame, the filter screen plate is driven to lift the rehydrated raw material inside the water tank to the outside. The rotating platform drives the long cylindrical slot seat to rotate the second electric telescopic rod, causing the filter screen plate to rotate to a position facing the feed end of the first lifting conveyor. The third electric telescopic rod extends and drives the filter screen plate, causing it to rotate upward to an inclined state with the assistance of the rotating seat. This allows the red algae raw material on the surface of the filter screen plate to be poured into the feed end of the first lifting conveyor along the inclined surface of the filter screen plate. The first lifting conveyor lifts and transports the rehydrated raw material inside to the feed end of the drum washing machine, and the second lifting conveyor lifts and transports the fresh red algae raw material inside to the feed end of the drum washing machine.

[0012] 2. The material on its surface is conveyed to the area below the top cover via a chain conveyor. Four linear motors start synchronously, driving the top frame downwards so that the bottom rods insert into the material. The first motor, in conjunction with the screw assembly, drives the limiting slot frame. The four limiting pins, in conjunction with the limiting slot frame, move synchronously to the left, driving the corresponding sliders below to move to the left along the sliding rods. The four sliders move outwards along the four sliding rods, spreading the material outwards with the help of the four bottom rods to increase the subsequent rinsing area. The linear motors shorten, driving the top frame upwards to reset the bottom rods. The four micro-motors... The telescopic rod drives the corresponding collar to move downwards along the bottom rod to clean the seaweed material wrapped around the outside of the bottom rod. The chain conveyor continues to transport the material to the left so that it passes through the inside of the upper and lower array nozzles. The water supply equipment supplies water to the pressurizing pump. After pressurization, the water is sprayed out from the upper and lower array nozzles to clean the sea salt and mud on the surface of the material by high-pressure spraying. After cleaning, the chain conveyor lifts the material and enters the internal work station from the discharge end of the trough shell through the feed end of the ultrasonic cleaner. The water supply equipment performs ultrasonic cleaning inside the ultrasonic cleaner.

[0013] This system enables fully automated collaborative operation, improving production efficiency while offering flexible multi-process adaptability. It allows for automatic switching and precise adaptation of processes for different types of red algae raw materials and different models of carrageenan products, broadening the compatibility range of raw materials and products, enhancing the versatility and market adaptability of the production line, and achieving precise and efficient control of raw material rehydration. This ensures that the raw materials are fully and uniformly softened, avoiding problems such as insufficient local rehydration leading to inadequate subsequent crushing or low extraction efficiency. At the cleaning operation level, a graded and progressive cleaning system has been constructed, achieving precise targeted removal of different types of impurities, improving the cleanliness of raw materials, and reducing the impact of impurities on subsequent extraction processes and product purity.

[0021] As a preferred option, further, such as Figure 5 , Figure 6 and Figure 7As shown, the soaking mechanism 7 includes: a water tank 71, a conveyor 72, a short cylinder slot seat 73, a first telescopic frame 74, a first electric telescopic rod 75, a first mounting frame 76, a pressure plate 77, a rotating platform 78, a long cylinder slot seat 79, a second telescopic frame 710, a second electric telescopic rod 711, a second mounting frame 712, a rotating seat 713, a third electric telescopic rod 714, and a filter plate 715.

The water filling end inside the water tank 71 is connected to the water supply equipment 9 through a pipe. The water tank 71 is a custom-made refill water tank, and the whole is made of stainless steel. The tank is constructed from welded steel plates, with a mirror-polished inner wall to reduce material residue. An electromagnetic flow meter and electric valve are installed on the pipeline connecting the water inlet of the tank 71 to the water supply equipment 9, allowing for precise water injection at a specified ratio under the control of the sub-control box 2. The bottom of the tank 71 also has a drain outlet, connected to the wastewater collection equipment 10 via a pipeline for discharging wastewater after rehydration. A conveyor 72 is fixedly mounted on the right side of the outer surface of the tank 71 along the front-to-back direction using a bracket.

A guide pipe is provided below the discharge end to guide the raw materials to fall evenly into the rehydration area inside the water tank 71. The control box 2 can automatically adjust the conveying speed or start and stop according to the liquid level and raw material accumulation in the water tank 71 to avoid overfeeding and insufficient rehydration. The short cylinder slot seat 73 is fixedly installed in the middle of the rear top of the outer surface of the water tank 71.

The pressure plate 77 is installed at the bottom of the first mounting frame 76. A groove is opened in the middle of the front side of the pressure plate 77. The pressure plate 77 can oscillate up and down in the liquid in the water tank 71 under the drive of the first electric telescopic rod 75, stirring the dried red algae raw material, breaking the liquid film on the surface of the raw material, promoting water penetration, and improving the rehydration efficiency.The rotating platform 78 is fixedly installed at the top of the base platform 1 and located in the lower center of the front side of the water tank 71. The rotating platform 78 is electrically connected to the control box 2. The rotating platform 78 is a servo precision rotating platform, which can drive the upper long cylindrical slot seat 79, filter screen plate 715 and other components to rotate as a whole, realizing the directional transfer of raw materials after rehydration from the water tank 71 to the first lifting conveyor 6.

The long cylindrical slot seat 79 is fixedly installed at the top of the rotating end of the rotating platform 78 in the vertical direction. The second telescopic frame 710 is inserted into the top of the inside of the long cylindrical slot seat 79 in the vertical direction. 710 transmits power to the second electric telescopic rod 711, driving the second connecting frame 712 and the filter plate 715 to move up and down synchronously.

The second electric telescopic rod 711 is a heavy-duty precision electric telescopic rod, which can provide power for the lifting and lowering of the filter plate 715, driving the filter plate 715 to lift the rehydrated raw material from the bottom of the water tank 71 upwards, or downwards. Once in its initial position, the control box 2 can precisely control the lifting stroke and speed of the second electric telescopic rod 711, ensuring a smooth lifting process and preventing material spillage. The second mounting frame 712 is fixedly installed on top of the second telescopic frame 710 along the vertical direction, and the second mounting frame 712 is Z-shaped. There are two rotating seats 713, which are fixedly installed on the left and right rear ends of the second mounting frame 712 respectively. The third electric telescopic rod 714 is rotatably installed on the front right side of the second mounting frame 712 via a rotating shaft seat. The third electric telescopic rod 714 is electrically connected to the control box 2. The third electric telescopic rod 714 is a small precision electric telescopic rod, which drives the filter plate 715 to rotate around the base through the telescopic action. The rotating seat 713 achieves tilted unloading. The control box 2 can control the extension and retraction of the third electric telescopic rod 714, precisely adjusting the tilt angle of the filter plate 715. The filter plate 715 is fixedly installed on the top of the rotating ends of the two rotating seats 713. The bottom left and right sides of the filter plate 715 are respectively connected to the telescopic ends of the two third electric telescopic rods 714 through rotating shafts. The filter plate 715 is a custom-made stainless steel filter plate. In its initial state, the filter plate 715 is horizontally located at the bottom of the water tank 71, which can block the passage of red algae raw materials while allowing water to drip smoothly. It can support the raw materials in the water tank 71 after rehydration, achieving preliminary drainage and separation of raw materials and water. Then, through a flipping action, the raw materials are transferred to the first lifting conveyor 6.

[0022] The specific tasks are as follows: Step 1: The central control room pre-starts the auxiliary systems. The compressed air system, steam supply system, and deionized water preparation system inside the auxiliary systems are started. The compressed air system ensures that the air pressure of each pneumatic device is stable at the threshold. The steam supply system makes the steam pressure reach the threshold. The deionized water preparation system prepares deionized water and stores it in the pure water tank. The alcohol recovery and distillation system, steam recovery system, and sewage treatment system are started, so that the equipment is in a standby ready state. Step 2: Workers feed dried red algae into the feed end of conveyor 72, while simultaneously feeding fresh red algae into the feed end of the second lifting conveyor 8, achieving synchronized feeding of dried and fresh materials. The central control room controls the sub-control box 2 via a remote communication link. According to its internal preset program, sub-control box 2 synchronously activates conveyor 72, the first electric telescopic rod 75, the second electric telescopic rod 711, the rotating platform 78, the third electric telescopic rod 714, the first lifting conveyor 6, the second lifting conveyor 8, and the drum washing machine 5, ensuring coordinated startup of all equipment. Conveyor 72 smoothly transports the dried red algae into the water tank 71 according to the preset quantitative conveying parameters. The water supply equipment 9, according to the instructions of sub-control box 2, supplies water into the water tank 71... Deionized water is automatically injected according to a 1:15 ratio of algae to fresh water. The first electric telescopic rod 75 initiates a shortening action, driving the first telescopic frame 74 to move downward along the inner guide structure of the short cylinder slot seat 73. This, in turn, drives the pressure plate 77 to move downward synchronously through the transmission action of the first mounting frame 76, immersing the pressure plate 77 in the liquid within the water tank 71. To enhance the rehydration effect, the first electric telescopic rod 75 repeatedly extends and shortens, causing the pressure plate 77 to move up and down in the liquid, vibrating and stirring the mixture of dried raw materials and water. This stirring process lasts for 2-4 hours, breaking the liquid film on the surface of the raw materials and allowing water to fully penetrate into the dried algae, completing the rehydration and softening process. After stirring and soaking, the first electric telescopic rod 75 returns to its original position and extends, driving... The dynamic pressure plate 77 moves upward and disengages from the water tank 71 to avoid interfering with subsequent raw material discharge. The second electric telescopic rod 711 extends, driving the second telescopic frame 710 to move upward along the inner side of the long cylindrical slot seat 79. Through the second mounting frame 712, the filter screen plate 715 is lifted upward from the bottom of the water tank 71, raising the rehydrated raw material inside the tank to the outside. During the lifting process, excess water adhering to the surface of the raw material drips naturally through the mesh of the filter screen plate 715, achieving temporary drainage and reducing water consumption in subsequent cleaning processes. The rotating platform 78 starts, driving the long cylindrical slot seat 79 and the second electric telescopic rod 711 and filter screen plate 715 to rotate as a whole until the filter screen plate 715 is directly facing the feed end of the first lifting conveyor 6. At the top position, the third electric telescopic rod 714 extends, driving the filter plate 715 to rotate upwards to an inclined state with the cooperation of the rotating seat 713. Using gravity, the rehydrated red algae material on the surface of the filter plate 715 slides along the inclined surface into the feed end of the first lifting conveyor 6. The first lifting conveyor 6 starts, lifting and conveying the rehydrated material to the feed end of the drum washing machine 5. Simultaneously, the second lifting conveyor 8 lifts and conveys the fresh red algae material to the feed end of the drum washing machine 5, achieving the convergence of dry and fresh materials at the feed end of the drum washing machine 5. The water supply equipment 9 supplies water to the pump inside the drum washing machine 5 through pipelines. After the red algae material enters the screen drum of the drum washing machine 5 from the feed end, the drive motor inside the drum washing machine 5 starts.The screen drum rotates at a constant speed of 10-20 r / min. An internal water pump, in conjunction with a spray nozzle, sprays high-pressure water onto the rotating raw material. Utilizing the combined effects of rotation, tumbling, and high-pressure washing, impurities such as shells, sand, and decaying algae are removed from the raw material. The cleaned, qualified algae are discharged from the outlet as the drum rotates, entering the feed end of the subsequent trough-type outer shell 32. Wastewater generated during the washing process is discharged through the drain at the bottom of the drum into the wastewater collection device 10 for centralized collection and treatment. Step 3: The qualified algae discharged from the discharge end of the drum cleaner 5 slides down the inclined guide surface of the feed end of the trough shell 32 onto the conveying surface of the chain conveyor 33. The preset program inside the control box 2 activates the chain conveyor 33, the linear motor 37, the first motor 310, the micro electric telescopic rod 316, and the ultrasonic cleaner 4. The chain conveyor 33 conveys the raw material on the surface to the left at a constant speed. When the raw material is conveyed to the working area below the top cover 36, the linear motors 37 on all four sides start to extend synchronously, driving the top frame 38 to move downward as a whole, so that the four bottom rods 315 installed below the top frame 38 are vertically inserted into the raw material pile. Then the first motor 310 starts, driving the screw in the screw assembly 39 to rotate. The rotation of the screw... The screw nut and the lower limiting slot 314 move to the left. Driven by the limiting slot 314, the four limiting pins 313 inserted inside move to the left simultaneously, driving the sliders 312 below them to slide to the left along their corresponding sliding rods 311. Since the four sliding rods 311 are all inclined outwards from front to back in the left-right direction, the sliders 312 spread outwards simultaneously as they slide to the left, causing the four bottom rods 315 to spread outwards, spreading the accumulated material around them. This increases the contact area between the material and the subsequent rinsing water flow, preventing material accumulation from causing incomplete cleaning in certain areas. After the material is spread out, the linear motor 37 starts and shortens, driving the top frame 38 to move upwards, causing the bottom rods 315 to be pulled out of the material and reset. Four miniature electric telescopic rods 316 simultaneously extend, driving the collar 317, which is fitted around the base rod 315, to move downwards along the base rod 315. This scrapes and cleans any seaweed material that may be entangled on the surface of the base rod 315, preventing losses caused by material entanglement and ensuring smooth operation for the next use of the base rod 315. After cleaning, the chain conveyor 33 continues to transport the material to the left, allowing it to pass sequentially through the cleaning area between the upper and lower array nozzle pipes 35. Simultaneously, the water supply device 9 supplies water to the pressure pump 34. The pressure pump 34 pressurizes the water to a preset pressure and then delivers it through pipelines to the upper and lower array nozzle pipes 35. High-pressure water jets are sprayed from the nozzles of the array nozzle pipes 35, providing high-pressure spray cleaning to the material from both sides, ensuring the original... After the sea salt, mud, and sand residue on the surface of the material are thoroughly rinsed off, and the high-pressure spray cleaning is completed, the chain conveyor 33 continues to lift and transport the material forward. After being discharged from the outlet end of the trough-type outer shell 32, the material enters the internal working position of the ultrasonic cleaner 4 through the feed end guide structure. The water supply equipment 9 simultaneously supplies water to the liquid storage chamber inside the ultrasonic cleaner 4. When the liquid level reaches the preset height, the ultrasonic cleaner 4 starts and generates high-frequency vibration through the internal ultrasonic transducer to form an ultrasonic field for ultrasonic fine cleaning of the material. This allows it to penetrate deep into the gaps and folds of the material, removing fine impurities that cannot be removed by high-pressure spraying. The cleaning water generated during the ultrasonic cleaning process flows into the sewage collection equipment 10 through the drain outlet of the ultrasonic cleaner 4.The algae, after ultrasonic cleaning, are treated together with the previously treated wastewater. The cleaned algae, then lifted by the ultrasonic cleaner 4, are transported from their discharge end to the feed end of a fully automatic shear crusher, completing the entire raw material pretreatment process and preparing for subsequent crushing and extraction steps. Step 4: The fully automatic shear crusher crushes the algae to the specified particle size. The particle size detection sensor detects the output. Unqualified particles are automatically returned for re-crushing. The crushed algae are transported to the industrial colloid mill through pipeline. They are mixed and ground into a slurry with a particle size ≤0.5mm at a ratio of algae:fresh water = 1:5. Then, they enter the material storage tank. The tank is stirred at low speed to prevent sedimentation. The algae slurry in the material storage tank is pumped to the first fully automatic belt filter press. It is filtered to a moisture content of 60% to 70%. The drained algae mud is transported to the alkali modification treatment area through pipeline conveyor. Step 5: The fully automatic alkali solution preparation system automatically prepares a 2%–5% KOH / NaOH solution according to the preset formula. The concentration is precisely controlled by a density sensor. The prepared alkali solution is transported to a constant temperature alkali solution tank for preheating at 60°C. The algae sludge and alkali solution are precisely fed into a constant temperature closed reactor at a solid-liquid ratio of 1:8 to 1:10 via a metering pump. The system controls the reactor temperature to rise to 60–80°C and stirs at a speed of 30–50 r / min for 2–4 hours. After alkali treatment, the algae enters a continuous water washing and neutralization machine via a belt conveyor. Countercurrent clean water spraying is used for washing. The online pH detection device at the discharge port monitors the pH value of the algae in real time. The system automatically adjusts the clean water flow or adds dilute alkali solution according to the detection results to ensure that the pH value of the algae is stable at 7.0–8.0 after neutralization. The neutralized algae enters a second fully automatic belt filter press and is filtered to a moisture content of 65%–75%. The filter cake is transported to the hot water extraction zone via a pipeline conveyor.

[0023] Step 6: If producing λ-type carrageenan, the system controls the start of the bypass conveyor at the discharge end of the first fully automatic belt filter press in the raw material pretreatment section. The algae sludge is directly conveyed to the feed port of the continuous jacketed extraction vessel in the hot water extraction zone via the bypass conveyor, bypassing the alkali modification treatment zone.

[0024] Step 7: The deionized water produced from the deionized water preparation tank is transported to a hot water constant temperature tank, heated to 85-95℃ and kept at a constant temperature. The algae sludge and hot water are automatically fed into two parallel continuous jacketed extraction kettles at a solid-liquid ratio of 1:15-20. The system controls the temperature inside the kettle to be maintained at 85-95℃, and the extraction is carried out by stirring at a speed of 20r / min for 3-5 hours. The two extraction kettles adopt a "one in, one out" mode to achieve continuous production. The extracted liquid is transported to a fully automatic plate and frame filter press to remove insoluble impurities such as algae residue. The crude carrageenan water extract is then filtered twice by a 500-mesh precision filter to further remove fine impurities. The filtered clear liquid is transported to the refining and purification area. Step 8: The clarified liquid automatically enters the automatic decolorization and impurity removal tank. The system precisely adds 0.5%–1% activated carbon or 3%–5% hydrogen peroxide via an automatic powder feeder, controlling the tank temperature at 60–70℃. After stirring and decolorizing for 30–60 minutes, the liquid is filtered through a plate and frame filter to remove the activated carbon, yielding a colorless and transparent carrageenan clarified liquid. The carrageenan clarified liquid is then transported to a fully automatic ion exchange desalination system, where it sequentially passes through three cation and anion exchange columns connected in series to remove impurities. The system monitors the conductivity in real time using an online conductivity meter. When the conductivity exceeds the standard, it automatically switches to a backup exchange column. The failed column automatically enters the regeneration process. Industrial-grade products skip this step. The clarified liquid after desalination... The carrageenan enters a 25°C constant-temperature alcohol precipitation tank. The system controls the alcohol storage tank to add alcohol precisely at a ratio of 1:1 to 2 (95% ethanol / isopropanol = 1:1~2) through an alcohol metering pump and pipeline mixer. After low-speed stirring for 10 minutes, the mixture is allowed to stand for 30 minutes to allow the carrageenan to fully precipitate. The precipitated liquid is then transported to a fully automatic centrifugal washing and dehydration machine. The wet carrageenan precipitate is first separated, and then automatically sprayed with 70% to 80% dilute alcohol to remove residual salts and pigments. Finally, it is centrifuged and dehydrated to a moisture content of 40% to 50%. The separated waste alcohol liquid is transported through a recycling pipeline to an alcohol recovery distillation system for purification and reuse. The wet carrageenan is transported to the drying and pulverizing area via a sealed conveyor.

[0025] Step 9: The wet carrageenan is automatically fed into the disc vacuum dryer via a vacuum feeder. The system controls the drying temperature at 60-70℃ and the vacuum degree at -0.08 to -0.09MPa for 4-6 hours. The online moisture content detector monitors the drying process in real time. When the moisture content drops below 8%, the carrageenan is automatically discharged. The dried carrageenan blocks are then fed into a fully automatic universal pulverizer and pulverized at a speed of 1000-2000 r / min. After pulverization, the carrageenan is sieved through an 80-120 mesh vibrating grading screen. Powder with qualified particle size is fed into a powder storage tank with nitrogen protection. Unqualified coarse powder is automatically returned for re-crushing. The powder storage tank is filled with nitrogen to prevent moisture absorption and agglomeration. Step 10: The carrageenan powder in the powder storage tank enters the fully automatic powder metering and packaging machine through the vacuum feeding pipe. It is accurately metered and packaged according to the preset specifications, with the metering accuracy controlled within ±0.2%. Small-sized packages are sealed by a vacuum sealing machine and then sealed a second time by an electromagnetic induction aluminum foil sealing machine. Large-sized packages are sealed using a sewing machine and a moisture-proof film. After packaging, the fully automatic inkjet printer automatically prints information such as production date, batch, and product grade. The vision inspection system simultaneously detects the clarity of the inkjet printing. Unqualified packages are automatically rejected. Qualified packages are conveyed to the fully automatic palletizer via a conveyor and automatically stacked according to the preset number of layers. After stacking, a pallet wrapping machine automatically wraps the pallet with cling film to prevent it from scattering during transportation. Step 11: The finished pallets that have been palletized are automatically transported by AGV transport vehicles to the temperature and humidity-controlled warehouse in the finished product temporary storage area. The warehouse management system in the central control room records the storage location information. After a batch of production is completed, the system starts the CIP in-situ cleaning system for each tank and pipeline, and automatically circulates the acid and alkali cleaning solution to clean the equipment. The cleaning wastewater is then transported to the sewage treatment system. After cleaning is completed, the equipment and auxiliary systems of each section are shut down in sequence, and the central control room automatically generates and stores the production data report for that batch.
