[0018] Compared with the prior art, the present application has the following advantages:

[0019] 1. The raw material is lifted by a conveyor and poured into the mesh surface of the first chamber. The solvent pump station pumps the internally stored solvent into the first nozzle pipe, which sprays out to form a mist curtain. The blower generates airflow that passes through the mesh surface, causing the raw material particles on the mesh surface to be suspended and dispersed in the airflow. The airflow carries the raw material particles along the inner cavity of the first chamber to the mist curtain below the first nozzle pipe, achieving uniform mixing of solvent and raw material. The mixed raw material enters the bottom tank from the hopper. The solvent pump station pumps the internally stored solvent into the second nozzle pipe, which sprays out into the bottom tank. The first motor drives the stirring rod to rotate in the inner cavity of the bottom tank, so that the stirring rod agitates the raw material in the bottom tank evenly. The solution is prepared by the first electric telescopic rod extending and retracting, which drives the mounting bracket to move upward or downward under the limiting action of the limiting component. This allows the stirring rod to move upward or downward along the inner cavity of the slot sealing plate inside the bottom tank with the cooperation of 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 air bubbles generated by stirring. The third pump pumps the solution after stirring in the inner cavity of the bottom tank into the centrifugal filter. The centrifugal filter removes insoluble impurities from the solution, resulting in a relatively pure carrageenan solution. The first pump pumps the carrageenan solution inside the centrifugal filter into the storage tank for storage.

[0020] 2. The carrageenan solution stored in the storage tank is pumped into two degradation reaction tanks by the second pump. Inside the degradation reaction tanks, the carrageenan solution is mixed with carrageenase for enzymatic hydrolysis to generate oligosaccharides. The fourth pump then pumps the oligosaccharides from the degradation reaction tanks into the third nozzles of several mold units through a diversion valve. The third nozzles inject 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 chamber, and the third electric telescopic rod drives the top plate to lift 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 rotate the first gears on both sides, causing the first roller seats on both sides to move in the front-back direction 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, raising and lowering the installation island to the specified height position. The electric suction cup moves to the corresponding position above the mold shell and adsorbs and grabs the oligosaccharide product. The fourth motor drives the rotating seat to rotate the installation arm under the transmission belt, causing the installation arm to drive the electric suction cup to rotate to the position inside the material cart, so as to place the oligosaccharide inside the material cart.

[0021] In summary, the present application can realize the automation and continuity of carrageenan oligosaccharide preparation process, improve production efficiency, enhance uniform mixing and filtration of raw materials in the pretreatment process, obtain relatively pure high-quality carrageenan stock solution, improve freeze-drying efficiency, retain oligosaccharide active ingredients, and realize precise flexible demolding operation and efficient and accurate product transfer after drying.

The third spray pipe (53) perfuses the oligosaccharide into the inner cavity of the mold shell (52) for freeze-drying; Step eight: After drying, the second electric telescopic rod (51) is elongated to drive the mold shell (52) to extend out of the inside of the refrigeration box (41), and the third electric telescopic rod (56) is elongated to drive the top plate (55) to move upward inside the slot seat (54), so as to lift the shaped oligosaccharide product in the mold shell (52) out of the inner cavity of the mold shell (52); Step nine: The second motor (67) drives the rotating shaft (65) to rotate the upper and lower first gears (66), which rotate along the upper and lower first gear racks (63) and drive the upper and lower first roller seats (64) to move along the first guide rail frame (62) in the front and back directions, and the third motor (611) drives the second gear (612) to rotate, which rotates along the second gear rack (69) and drives the second roller seat (610) to move along the second guide rail frame (68), so that the installation island (613) is lifted to a specified height position, and the electric suction cup (618) is moved to a position above the mold shell (52) and adsorbs and grabs the oligosaccharide product, and the fourth motor (614) drives the rotating seat (615) to rotate the installation arm (617) under the transmission of the transmission belt (616), so that the installation arm (617) drives the electric suction cup (618) to rotate to the position inside the material cart (45), so as to place the oligosaccharide inside the material cart (45); Step ten: The material cart (45) transports the dried oligosaccharide product to the detection area for component analysis, activity detection and appearance inspection to ensure that the product meets the standards.
