Description

Technical Field

[0001] The present application relates to the field of kelp processing, and in particular to a device and method for processing dried and ready-to-eat kelp. Background Art

[0002] As an important branch of marine functional food, ready-to-eat kelp has gradually become a hot spot in the field of healthy snacks due to its high dietary fiber, minerals and polysaccharide active ingredients. Traditional ready-to-eat kelp products are mostly directly packaged or heat-processed after seasoning, but the processing method has a significant impact on the product texture and nutritional retention. The current mainstream industrial processing technology is mainly frying dehydration and hot air drying. Although it can extend the shelf life and give a crispy taste, process defects lead to problems such as loss of nutritional value and insufficient texture stability.

[0003] Existing patent CN102232581A discloses a method for processing a snack food by deep-frying kelp and potatoes. The main ingredients are sliced ​​and then fried at high temperature for dehydration, and seasonings are added to make a potato chip-like product. Although this process can achieve rapid dehydration and enhance the flavor, the frying process causes a large loss of water-soluble vitamins (such as B vitamins) and heat-sensitive polysaccharides in the kelp, and produces harmful substances such as trans fatty acids, which poses a risk of oil oxidation and rancidity. In addition, the oil content of fried products is as high as 20%-30%, which is contrary to the current trend of low-fat and healthy consumption, limiting its application in specific populations.

[0004] Existing patent CN20221210 proposes a method for processing kelp chips, which quickly dries the pretreated kelp chips in hot air at 170-190°C to remove moisture through high-temperature thermal action. Although this process can avoid the problem of oil intake, high temperature causes the degradation of kelp chlorophyll and browning of color, and protein denaturation makes the product hard and rough in taste. A method for preparing instant kelp (CN20190129) further adopts a molding process of hot air drying combined with starch addition, but too long hot air treatment time can easily cause the collapse of the kelp cell structure and poor rehydration, and the thermal decomposition rate of active ingredients such as fucoidan exceeds 40%6 at high temperature.

[0005] The core defects of the above two types of processes are: ① High-temperature processing destroys heat-sensitive nutrients. For example, the retention rate of vitamin C and brown algae polyphenols in frying or hot air drying is less than 50%; ② The texture control ability is limited. Fried products are prone to greasy feeling, and hot air drying causes kelp fiber to harden, making it difficult to achieve a "crispy and light" eating experience; ③ Energy consumption and environmental protection issues. Frying requires a continuous high-temperature oil bath, and hot air drying has low energy efficiency (thermal efficiency is usually less than 30%), neither of which meets the requirements of green manufacturing.

[0006] In contrast, freeze-drying technology can retain the original nutrients of kelp to the greatest extent by sublimating water at low temperature, while forming a porous and loose structure, giving the product a unique taste.

[0007] In the field of industrial dehydration of ready-to-eat kelp, freeze-drying technology has become an important direction for industry upgrading due to its unique low-temperature phase change characteristics. Compared with traditional drying processes that rely on heat conduction (such as hot air drying, sun drying or heat pump drying), this technology dehydrates the pretreated kelp in a vacuum low-temperature environment through the principle of ice crystal sublimation. While avoiding high-temperature thermal degradation, it can completely retain the water-soluble vitamins (such as VB12, folic acid), algae polysaccharides (fucoidan, kelp starch) and other active substances in the kelp cells, and maintain its natural emerald green color and flaky structural integrity. However, existing freeze-drying equipment has exposed significant defects in actual applications: its water vapor trap has insufficient density of condensation plate arrangement and inaccurate temperature gradient control, resulting in the inability to dissipate the phase change latent heat generated in the sublimation stage in time. Experimental data show that the water vapor capture efficiency of traditional devices is only 68%-75%. The residual water vapor condenses into ice crystals on the inner wall of the equipment, which not only increases the energy consumption of the vacuum pump group by 20%-30%, but also causes pressure fluctuations in the freeze-drying chamber (±15Pa), causing the collapse rate of the porous structure of the kelp to exceed 12%. In response to this technical bottleneck, the present invention innovatively designs a dry and ready-to-eat kelp processing device, which optimizes the surface energy parameters of the collector and the refrigerant circulation mode to achieve directional migration of water vapor and efficient solidification. Summary of the invention

[0008] In view of the above problems, the present application provides a device and method for processing dry and ready-to-eat kelp, which realizes directional migration of water vapor and efficient solidification by optimizing the surface energy parameters of the collector and the refrigerant circulation mode.

[0060] See also Figure 1-16 This embodiment provides a dry and ready-to-eat kelp processing device, comprising:

[0061] A cleaning unit for cleaning kelp.

[0062] The cleaning unit can refer to the existing technology, such as a kelp cleaning and desalting device with patent publication number CN221179272U. The cleaning unit adopts a drum 204-type cleaning structure, with a built-in spray head and a drainage board to achieve physical flushing of the kelp surface mud and sand. Through the airflow pipe design combined with a dynamic desalting liquid circulation system, the desalination process is completed synchronously, and a feedback control module with adjustable salt concentration is equipped to ensure that the salt concentration after desalination is stable within the preset threshold. Another example is a kelp cleaning unit with sand and impurity removal function with patent publication number CN208837034U. Through the integrated desalination-cleaning design, the time loss caused by process switching is reduced.

The working principle of this specific embodiment is as follows: first, the disassembled kelp is put into the feed hopper 210 and enters the interior of the fixed cylinder 201, and the drive motor 202 is started to drive the drum 204 to rotate, so that the kelp inside the drum 204 rolls and is cleaned, and the mud and sand of the kelp pass through the screen 205 and fall between the arc plates 206. The arc plates 206 rotate at the same time and push the soil inside the fixed cylinder 201 upward, and discharge it to the outside of the fixed cylinder 201 through the sewage outlet 208. The kelp is put into the interior of the fixed box 211, and the vibration motor 215 is started to drive the movable net 214 to vibrate up and down. Under the elastic force of the first spring 216, the movable net 214 is promoted to shake up and down quickly, and the soil on the kelp is vibrated off. Through the coordinated use of the fixed cylinder 201, the driving motor 202, the stirring shaft 203, the drum 204, the screen 205, the arc plate 206, the first filter 207, the sewage outlet 208 and the feed hopper 210, the cleaned soil can be pushed outwards at the same time during the cleaning of the kelp soil bag, reducing the pollution degree of the cleaning water source, improving the water quality and achieving the purpose of improving the kelp cleaning efficiency, thereby improving the processing efficiency of the cleaning unit. Through the coordinated use of the fixed box 211, the dust collecting frame 212, the fixed rod 213, the movable net 214, the vibration motor 215 and the first spring 216, the kelp is put into the interior of the fixed box 211, the vibration motor 215 is started to drive the movable net 214 to vibrate up and down, and the elastic force of the first spring 216 promotes the movable net 214 to shake up and down quickly, so that the dust attached to the surface of the kelp is initially cleaned, and a large amount of soil in the kelp is shaken, which is conducive to the rapid processing of the subsequent kelp cleaning work.Furthermore, a filter box 217 is fixed on the top of the fixed cylinder 201 and located on the other side of the feed hopper 210, and a first water pump 218 is installed at the bottom of the filter box 217. A water inlet pipe 219 is fixed to the input end of the first water pump 218, and one end of the water inlet pipe 219 is connected to one end of the fixed cylinder 201, and the output end of the first water pump 218 is connected to the filter box 217. A filter layer 220 is fixed inside the filter box 217, and a water outlet pipe 221 is provided on the side of the filter box 217 close to the feed hopper 210.

The filtered sewage is transported to the feed hopper 210 through the water outlet pipe 221, so that the sewage is quickly filtered and recycled, thereby improving the environmental protection of the cleaning unit. In other embodiments, guide plates 506 are provided on both sides of the fixed cylinder 201, and the guide plates 506 are tilted on both sides of the fixed cylinder 201. The tilted guide plates 506 make it easier for silt impurities to flow outward, which is convenient for collecting soil impurities. In other embodiments, a support frame 305 is fixed to the bottom of the fixed box 211, and one side of the support frame 305 is fixedly connected to one side of the fixed cylinder 201.

[0067] Freeze drying unit, used to sublimate the water in kelp at low temperature.

[0068] The freeze-drying unit includes a drying box 101, and the interior of the drying box 101 is provided with a first refrigeration unit 109, a vacuum pump group 112 and an infrared radiation heating plate 117. The interior of the drying box 101 is provided with a temperature sensor and a vacuum sensor. The temperature sensor monitors the temperature change of the kelp in real time and feeds back the data to the intelligent control system to ensure that the temperature of the kelp is uniform during the pre-freezing process, forming a small and uniform ice crystal structure, which is conducive to subsequent drying work. The vacuum pump group 112 includes a multi-stage Roots pump and a rotary vane pump. The vacuum pump group 112 adopts a combination of a multi-stage Roots pump and a rotary vane pump, which can quickly reduce the pressure in the drying box 101 to the required vacuum degree, and monitors and feedbacks in real time through a vacuum sensor to ensure that the vacuum degree is stable within a set range. Using the infrared radiation heating plate 117, heat can be radiated evenly to the kelp to promote water sublimation.

[0069] An L-shaped carrier plate 110 is provided inside the drying box 101 , and the kelp can be placed on the L-shaped carrier plate 110 . The L-shaped carrier plate 110 has good thermal conductivity and air permeability, thereby ensuring that the kelp is heated evenly during the drying process.

[0070] The outside of the drying box 101 is provided with a heat insulating layer 108, and the heat insulating layer 108 is made of polyurethane foam. The heat insulating layer 108 can be used to keep the inside of the drying box 101 warm, which is beneficial to the freeze-drying of the kelp.

[0071] A steam exhaust groove 111 is provided at the bottom of the drying box 101, and a water collecting shell 102 is fixedly connected to the upper surface of the drying box 101. A condensing coil 115 is provided inside the water collecting shell 102. A second refrigeration unit 107 is provided on the upper surface of the drying box 101, and the second refrigeration unit 107 is connected to the condensing coil 115. The second refrigeration unit 107 can be used to cool the condensing coil 115. At the same time, the sublimated water vapor will enter the water collecting shell 102 from the steam exhaust groove 111. When the water vapor contacts the condensing coil 115, it will quickly condense into ice on its surface, thereby realizing efficient water vapor capture.

[0072] The upper surface of the water-collecting shell 102 is inlaid with annularly arranged blowing pipes 106, and the output ends of the blowing pipes 106 are laterally arranged. The input ends of a group of blowing pipes 106 are commonly connected to the air supply pipe 105. The outer surface of the air supply pipe 105 is connected to the first fan 103 through the connecting pipe 104. The first fan 103 can blow air into the air supply pipe 105, and the blowing pipes 106 will blow air into the water-collecting shell 102, thereby accelerating the flow speed of water vapor, allowing the water vapor to contact the condensing coil 115 faster, and further improving the water capture speed.

[0073] A conical guide tube 116 is fixedly connected to the upper surface of the drying box 101, and the conical guide tube 116 is coaxially arranged with the exhaust groove 111. The ice on the condensing coil 115 will fall on the outside of the conical guide tube 116 after melting, which can prevent water from falling into the exhaust groove 111 and entering the interior of the drying box 101.

[0074] The outer surface of the water-collecting shell 102 is connected to a drain pipe 114, and the outer surface of the drain pipe 114 is connected to a control valve 113. By opening the control valve 113, the melted ice water will be discharged from the water-collecting shell 102 along the drain pipe 114, making it convenient for the staff to collect the melted water.

[0075] The working principle of the freeze-drying unit is as follows: when in use, the kelp is placed on the L-shaped carrier plate 110, and then the first refrigeration unit 109 is started to freeze the kelp, and then the vacuum pump group 112 is started to reduce the pressure in the drying box 101 to the required vacuum degree. At the same time, the infrared radiation heating plate 117 can radiate heat to the kelp evenly to promote the sublimation of water. The sublimated water vapor will enter the water collection shell 102 from the exhaust groove 111. At the same time, the second refrigeration unit 107 is controlled to work, and the temperature of the condensing coil 115 will drop rapidly. When the water vapor contacts the condensing coil 115, it will quickly condense into ice on its surface. At the same time, the first fan 103 can be controlled to work, and the air supply pipe 105 will exhaust air to the inside of the blowing pipe 106, and the blowing pipe 106 will blow wind to the inside of the water collection shell 102, thereby accelerating the flow speed of water vapor, and the water vapor contacts the condensing coil 115 faster, further improving the water collection speed.

[0076] The cleaning unit, cutting and forming unit, and freeze-drying unit are continuously connected by a conveyor belt to form an integrated production line. Specifically, a multi-stage intelligent conveyor belt can be used to achieve seamless connection of the three units of cleaning, cutting, and freeze-drying. For example, a segmented conveyor structure can be adopted. The discharge end of the cleaning unit uses a stainless steel mesh belt for conveying (linear speed 0.5 - 1.2 m / min), with a mesh hole diameter of 3 mm, synchronously completing water drainage and residue filtration; the inlet of the cutting and forming unit uses a conveyor belt configured with rubber (surface anti-slip pattern depth 0.8 mm), and the pressure sensor is used to detect the accumulated thickness of kelp in real time, and feedback to adjust the conveying speed (accuracy of ±0.1 m / min) to prevent congestion in cutting feed; the conveying section of the freeze-drying unit can use a low-temperature resistant silicone conveyor belt (-50°C anti-brittle), and an infrared positioning sensor is equipped at the end to ensure that the kelp slices accurately fall into the material tray of the freeze-drying chamber 101 (positioning error ≤ 2 mm). At the same time, a collaborative control logic can also be added. For example, a synchronous start-stop module. When the freeze-drying unit pauses due to vacuum degree fluctuations, the PLC controller synchronously reduces the speed of the front conveyor belt (down to 30% of the standard speed at the lowest) to avoid kelp accumulation; a status feedback mechanism: the photoelectric counter at the outlet of the cutting unit counts the output in real time, dynamically matches with the condensation efficiency of the water capture shell 102 of the freeze-drying unit, and adjusts the freeze-drying cycle (adjustable from 15 - 25 minutes) through the PID algorithm. To prevent cross-contamination, an intermediate isolation section can be set between the units, and an air curtain device (wind speed 8 m / s) is set at the connection of cleaning, cutting, and freeze-drying to form an air flow barrier to block the diffusion of water vapor and debris. A cleaning linkage function is set. After the daily production is completed, the conveyor belt starts the reverse operation mode, and cooperates with a high-pressure spray head (pressure 3 MPa) to automatically clean the residues on the belt surface. The waste heat generated during the preheating stage of the freeze-drying unit is recovered to the surface dehydration process of the kelp in the cutting unit through a heat conduction pipe, reducing the comprehensive energy consumption.

[0077] Through the cooperation of the blower, air delivery pipe 105 and air blowing pipe 106 provided in the present invention, by the operation of the blower, the air delivery pipe 105 blows air into the air blowing pipe 106, and the air blowing pipe 106 blows air into the water capture shell 102, thereby accelerating the flow rate of water vapor, enabling the water vapor to contact the condensation coil 115 faster, and further improving the water capture speed. Through the provided conical guide cylinder 116, when the frozen water vapor outside the condensation coil 115 melts into water, the conical guide cylinder 116 guides it, thereby preventing water from entering the drying chamber 101 from the exhaust slot 111.

[0078] Through the provided infrared radiation heating plate 117, heat can be evenly radiated to the kelp, promoting the sublimation of moisture and being beneficial to the drying of the kelp.

[0079] In order to shorten the total freeze-drying time of kelp chips, in some embodiments, the cutting and forming unit includes an embossing mechanism, which includes a frame 401 and an embossing wheel 417. The top of the frame 401 is fixedly connected to a second auxiliary conveyor belt 402, and the top of the second auxiliary conveyor belt 402 is fixedly connected to a fixed frame 403. The inner top wall of the fixed frame 403 is fixedly connected to a cylinder 404, and the bottom of the cylinder 404 is fixedly connected to a lifting frame 405. The outer wall of the lifting frame 405 is fixedly connected to the cylinder 404.

The inner wall of the lifting frame 405 is inlaid with a bearing 408, and the inner ring of the bearing 408 is fixedly sleeved with the rotating roller 409. The operation of the second motor 407 can drive the rotating roller 409 to rotate, and then the rotating roller 409 can rotate through the inner ring of the bearing 408. The inner wall of the second groove 413 is provided with a slideway 411, and the slideway 411 is slidably connected with the movable plate 410, and the slideway 411 can play a role of limiting, so that the movable plate 410 will not be skewed when moving. The inner wall of the second groove 413 is provided with a channel 414, and the clamping block 415 is slidably connected with the channel 414. When the movable plate 410 moves, the clamping block 415 can move through the channel 414 under the action of the force. The rotating roller 409 is slidably connected with the through groove 418, and the clamping groove 416 is movably connected with the clamping block 415. Through the clamping of the clamping groove 416 and the clamping block 415, the position of the embossing wheel 417 is fixed, and the position of the embossing wheel 417 will not move automatically. During use, in the initial state, the block 415 is engaged with the slot 416 in the through slot 418 of the embossing wheel 417 to fix the spacing of the embossing wheel 417; when adjustment is required, the movable plate 410 is manually or pneumatically pushed to slide in the second groove 413, so that the block 415 is disengaged from the slot 416, and the spacing of the embossing wheel 417 is freely adjusted. The lifting frame 405 is pushed to move vertically by the cylinder 404 to control the contact pressure between the embossing wheel 417 and the kelp. The second motor 407 drives the rotating roller 409 to rotate through the coupling, and the embossing wheel 417 rotates synchronously with the rotating roller 409, and the surface texture (such as grid, wave pattern) is continuously embossed on the kelp. Furthermore, a pressure sensor can be integrated on the lifting frame 405 to monitor the embossing pressure in real time, and an alarm is triggered and automatically reset when the limit is exceeded.By means of the cylinder 404, the second motor 407, the rotating tube, the slot 416 and the embossing wheel 417, the movable plate 410 moves inside the second groove 413, and then can drive the block 415 to move inside the second groove 413, so that the block 415 is separated from the slot 416, and then the embossing wheel 417 is no longer limited, and the embossing wheel 417 can be moved, and the spacing between the plurality of embossing wheels 417 is moved to the spacing of the required thickness of the cut kelp, and the spacing between the embossing wheels 417 can be adjusted according to the embossing specifications of the required kelp, and then when kelp with different spacings is needed, different specifications and models of embossing wheels 417 are replaced, thereby greatly improving the applicability of the device. After embossing, the surface area of ​​the kelp increases, the diffusion path of water molecules is shortened during sublimation drying, and the total drying time is reduced.

[0080] Furthermore, a second spring 412 is fixedly connected to one side of the movable plate 410, and one end of the movable plate 410 passes through the slideway 411 and extends to the outside of the rotating roller 409. There are two movable plates 410, and the number of movable plates 410 on the two movable plates 410 is the same, and the two movable plates 410 are arranged in a mirror image. During use, the movable plates 410 can be moved by controlling the movement of the movable plates 410 from the outside of the rotating roller 409, and one end of the two movable plates 410 can be pinched to move the two movable plates 410 in opposite directions, thereby driving the card block 415 to move into the second groove 413, and then the card block 415 will be separated from the card slot 416, so that it is more convenient to control the card block 415 to engage with the card slot 416.

[0081] In some embodiments, a baking unit is also included. The baking unit is arranged between the cutting and forming unit and the freeze-drying unit, and they are connected continuously through conveyor belts. The baking unit is used to pre-dry the kelp. The pre-drying by the baking unit reduces the moisture content of the kelp from 80% to 40-50% (hot air drying at 60°C for 1-2 hours). Freeze drying only processes the remaining moisture, and the total freeze-drying time is shortened, reducing costs and increasing efficiency. The baking unit includes a baking frame 501, and a third auxiliary conveyor belt 502 is installed inside the baking frame 501. The third auxiliary conveyor belt 502 can be better ventilated, so that the hot air can evenly dry the kelp.

Each heating and baking device 503 includes a fixed frame 531 installed on the inner wall of the baking frame 501. A group of equidistantly arranged heating wires 532 are installed inside each fixed frame 531. The operation of the heating wires 532 can heat the upper part and the lower part of the kelp, so that the kelp can be evenly dried. A fixed plate 510 is installed inside the baking frame 501. A plurality of second fans 511 are installed on the fixed plate 510. The operation of the second fans 511 can blow air to the baked kelp, so that it can be cooled. A collection frame 507 is placed at the bottom of the baking frame 501. Two guide plates 506 are fixedly connected to the inner wall of the baking frame 501. The guide plates 506 can be used to guide the water dripping from the kelp and the residue of the kelp crisps. The collection frame 507 will collect the water and residue, which is convenient for the staff to centrally process. The inner wall of the baking frame 501 is fixedly connected to a group of equidistantly arranged suspension rods 509, and the outer surface of each suspension rod 509 is slidably connected to a group of equidistantly arranged sliders 508, and the bottom surface of each group of sliders 508 is fixedly connected to a positioning plate 504. The cooperation between the suspension rod 509 and the slider 508 can form a stable suspension for the positioning plate 504, and the positioning plate 504 can evenly divide the area above the third conveyor belt 502, thereby avoiding displacement and stacking during the kelp baking process.

The positioning structure 505 includes a connecting plate 551 fixedly connected to the front side of each positioning plate 504, each connecting plate 551 is slidably connected with a push rod 552, and the top of each push rod 552 is fixedly connected with a circular plate 553. The upper surfaces of a group of circular plates 553 are in contact with a stabilizing plate 554. The left and right ends of the stabilizing plate 554 are connected to the inner wall of the baking frame 501, and the outer surface of each push rod 552 is sleeved with a third spring 555. The elasticity of the third spring 555 can be used to push the circular plate 553, and the circular plate 553 will contact the stabilizing plate 554, thereby forming a stable connection plate 551, further enhancing the stability of the positioning plate 504, and preventing the positioning plate 504 from self-deviating.The bottom end of each push rod 552 is fixedly connected with a pull plate 556, and the pull plate 556 is provided to facilitate the staff to pull the push rod 552 downward, so that the positioning plate 504 can be conveniently moved. The working principle of this embodiment is: when in use, the spacing of the positioning plates 504 is first adjusted according to the width of the kelp, and the push rods 552 are pulled down in sequence, the circular plate 553 will be separated from the stabilizing plate 554, and then the push rods 552 are pulled to move, and the connecting plate 551 will drive the positioning plate 504 to move, and then the kelp is placed on the third auxiliary conveyor belt 502 and started to work, and the heating wire 532 is controlled to work at the same time. When the kelp passes through the heating wire 532, it will be heated and baked, which can prevent it from being displaced and stacked during baking. When the baked kelp crisps pass through the second fan 511, it will be blown to cool it down. The present invention also provides a method, and the method uses the dry and ready-to-eat kelp processing device as described in any of the above embodiments to make kelp.
