Description

Technical Field

[0001] The present invention relates to the technical field of carrageenan processing, and specifically provides an apparatus and method for preparing carrageenan oligosaccharides. Background Art

[0002] Carrageenan is a sulfated linear polysaccharide, mainly composed of D-galactose and 3,6-anhydro-D-galactose alternately linked by α-1,3 and β-1,4 glycosidic bonds. According to the number and position of sulfate groups, carrageenan is mainly divided into the following three types: κ-carrageenan, ι-carrageenan, and λ-carrageenan. Carrageenan oligosaccharides are a class of oligosaccharides obtained by degrading carrageenan. Carrageenan is a polysaccharide extracted from red algae seaweeds, while oligosaccharides are usually composed of 2 - 10 monosaccharides linked by glycosidic bonds. Carrageenan oligosaccharides retain some structural characteristics of carrageenan, and their basic constituent monosaccharides are mainly galactose and its sulfate esters. Different types of carrageenan oligosaccharides differ in the content, position, and linkage mode of sulfate groups, which also results in their different physicochemical properties and biological activities; In the prior art, the traditional preparation process of carrageenan oligosaccharides involves multiple independent steps, resulting in low efficiency and easy errors. The pretreatment method of raw materials in the preparation process of carrageenan oligosaccharides can lead to uneven mixing of raw materials and solvents, affecting the subsequent reaction efficiency. In addition, the drying efficiency of freeze-drying equipment is low, resulting in loss of active ingredients in the product. The removal of products from the freeze-drying equipment relies on a large amount of manual operation, resulting in low efficiency. Summary of the Invention

[0011] Compared with the prior art, the beneficial effects of the present invention are: 1. The raw materials are lifted by a lifting conveyor and poured onto the surface of the wire mesh plate inside the first box body. The solvent pump station pumps the internally stored solvent into the first spray head pipe and sprays it to form a mist curtain. An air current is generated inside the fan and passes through the surface of the wire mesh plate, causing the raw material particles on the surface of the wire mesh plate to be suspended and dispersed in the air current. The air current carries the raw material particles and moves along the inner cavity of the first box body to the mist curtain below the first spray head pipe, realizing the uniform mixing of the solvent and the raw materials. The mixed raw materials enter the bottom tank through the hopper. The solvent pump station pumps the internally stored solvent into the second spray head pipe and sprays it into the bottom tank. The first motor drives the stirring rod to rotate inside the inner cavity of the bottom tank, so that the stirring rod stirs the raw materials inside the bottom tank into a uniform solution. The first electric telescopic rod extends and retracts to drive the mounting rack to move upward or downward under the limiting action of the limiting component, so that the stirring rod moves upward or downward inside the bottom tank along the inner cavity of the slot sealing plate in cooperation with the first motor, thereby improving the stirring and mixing effect of the stirring rod. After stirring, the ultrasonic vibrator performs ultrasonic oscillation inside the solution to remove the bubbles generated by stirring inside the solution. The third pump body pumps the solution stirred inside the inner cavity of the bottom tank into the centrifugal filter. The centrifugal filter performs centrifugal filtration on the solution to remove insoluble impurities, obtaining a relatively pure carrageenan solution. The first pump body pumps the carrageenan solution inside the centrifugal filter into the storage tank for storage.

[0012] 2. The carrageenan solution stored inside the storage tank is respectively pumped into two degradation reaction tanks through the second pump body. Inside the degradation reaction tank, the carrageenan solution is mixed with carrageenase to carry out an enzymatic hydrolysis reaction to generate oligosaccharides. The fourth pump body pumps the oligosaccharides inside the degradation reaction tank into the third spray head pipes inside several mold units respectively under the diversion of the diversion valve. The third spray head pipes pour the oligosaccharides into the inner cavity of the mold shell for freeze-drying. The second electric telescopic rod drives the mold shell to extend out of the refrigeration box. The first electric telescopic rod drives the top plate to jack up the oligosaccharide product formed inside the mold shell out of the inner cavity of the mold shell. The second motor drives the rotating shaft to drive the first gears on the upper and lower sides to rotate, so that the first roller seats on the upper and lower sides move back and forth along the outside of the first guide rail frame. The third motor drives the second gear to move along the second rack and drives the second roller seat to move along the outside of the second guide rail frame, so that the installation island platform is lifted to the specified height position, and the electric suction cup is moved to the position above the mold shell at the corresponding position and adsorbs and grabs the oligosaccharide product. The fourth motor drives the rotating seat to drive the mounting arm to rotate under the drive of the transmission belt, so that the mounting arm drives the electric suction cup to rotate to the position inside the material trolley cavity to place the oligosaccharides inside the material trolley.

[0013] In summary, the present invention can automate and streamline the process flow for preparing carrageenan oligosaccharides, improve production efficiency, enhance the uniform mixing and filtration of raw materials during the pretreatment process to obtain a relatively pure and high-quality carrageenan raw solution, increase the freeze-drying efficiency, retain the active ingredients of oligosaccharides, and achieve precise and flexible demolding operations and efficient and accurate product transfer after drying is completed.

[0023] The working principle is as follows: Step 1: The staff takes κ-carrageenan as the starting raw material and pours the raw material into the interior of the lifting conveyor 21 from the internal feed port of the lifting conveyor 21. The staff controls the controller 8 to start the lifting conveyor 21, the solvent pump station 22, the fan 32, the first motor 317, the first electric telescopic rod 316, the ultrasonic vibrator 312, and the third pump body 310. The lifting conveyor 21 lifts the raw material and pours it onto the surface of the mesh plate 34 in the inner cavity of the first box body 33. The solvent pump station 22 pumps the stored solvent into the first spray head pipe 36 and sprays it to form a mist curtain. The fan 32 generates an air flow inside and passes through the surface of the mesh plate 34, causing the raw material particles on the surface of the mesh plate 34 to be suspended and dispersed in the air flow. The air flow carries the raw material particles and moves along the inner cavity of the first box body 33 to the mist curtain below the first spray head pipe 36, realizing the uniform mixing of the solvent and the raw material. The mixed raw material enters the bottom tank 39 through the hopper 35. The solvent pump station 22 pumps the stored solvent into the second spray head pipe 38 and sprays it into the bottom tank 39. The first motor 317 drives the stirring rod 318 to rotate in the inner cavity of the bottom tank 39, so that the stirring rod 318 stirs the raw material in the bottom tank 39 into a uniform solution. The first electric telescopic rod 316 extends and retracts to drive the mounting frame 315 to move up or down under the limiting action of the limiting component 314, so that the stirring rod 318 moves up or down in the inner cavity of the bottom tank 39 along the slot sealing plate 311 in cooperation with the first motor 317, thereby improving the stirring and mixing effect of the stirring rod 318. After the stirring is completed, the ultrasonic vibrator 312 performs ultrasonic oscillation inside the solution to remove the bubbles generated by the stirring inside the solution. The third pump body 310 pumps the solution stirred in the inner cavity of the bottom tank 39 into the centrifugal filter 23. The centrifugal filter 23 performs centrifugal filtration on the solution to remove insoluble impurities, obtaining a relatively pure carrageenan solution. The first pump body 24 pumps the carrageenan solution in the centrifugal filter 23 into the storage tank 25 for storage; Step 2: The staff controls the controller 8 to start the second pump body 26, the degradation reaction tank 9, the refrigerator 44, the fourth pump body 42, the flow dividing valve 43, the second electric telescopic rod 51, the first electric telescopic rod 56, the second motor 67, the third motor 611, the electric suction cup 618 and the fourth motor 614. The second pump body 26 pumps the carrageenan solution stored inside the storage tank 25 into the two degradation reaction tanks 9 respectively. The staff inputs a certain amount of κ-carrageenase into the two degradation reaction tanks 9, and controls the reaction environment inside the degradation reaction tanks 9 to be 40 - 60 °C and the pH to be between 6 - 8. Inside the degradation reaction tanks 9, the carrageenan solution and the carrageenase are mixed to carry out an enzymatic hydrolysis reaction to generate oligosaccharides. The refrigerator 44 pumps the internal refrigerant into the refrigeration box 41 for circulation, so that the inside of the refrigeration box 41 reaches the specified freeze-drying temperature. The fourth pump body 42 pumps the oligosaccharides inside the degradation reaction tank 9 into the third spray head pipes 53 inside several mold units 5 respectively under the flow division of the flow dividing valve 43. The third spray head pipes 53 pour the oligosaccharides into the inner cavity of the mold shell 52 for freeze-drying. After drying is completed, the second electric telescopic rod 51 extends to drive the mold shell 52 to extend out of the inside of the refrigeration box 41. The first electric telescopic rod 56 extends to drive the top plate 55 to move upward inside the slot seat 54, and jacks up the formed oligosaccharide product inside the mold shell 52 out of the inner cavity of the mold shell 52. The second motor 67 drives the rotating shaft 65 to drive the upper and lower first gears 66 to rotate. While the upper and lower first gears 66 rotate, they move along the upper and lower first racks 63, and drive the upper and lower first roller seats 64 to move in the front-back direction along the outside of the first guide rail frame 62. The third motor 611 drives the second gear 612 to rotate. While the second gear 612 rotates, it moves along the second rack 69, and drives the second roller seat 610 to move along the outside of the second guide rail frame 68, so that the installation island platform 613 is lifted to the specified height position, and the electric suction cup 618 moves to a position above the corresponding mold shell 52 and adsorbs and grabs the oligosaccharide product. The fourth motor 614 drives the rotating seat 615 to drive the mounting arm 617 to rotate under the transmission of the transmission belt 616, so that the mounting arm 617 drives the electric suction cup 618 to rotate to the inner cavity position of the material cart 45, so as to place the oligosaccharides inside the material cart 45, and then the material cart 45 conducts subsequent quality inspection on the dried carrageenan oligosaccharide product.
