Technical Field

[0002] American ginseng is a perennial herbaceous plant of the genus Panax in the Araliaceae family. The root of American ginseng is cylindrical or spindle-shaped; American ginseng was first discovered in the Atlantic coastal jungles of the Montreal area and was named after its place of origin. It is of the same genus as ginseng but a different species.

[0003] The enzyme reaction process refers to the process of using the specific catalytic function of the enzyme catalyst to produce the required biochemical products with the help of technological means and bioreactor equipment. Compared with the fermentation process, it uses reaction-specific enzymes as catalysts, has no by-products, and is more convenient for process refining and product separation and purification. During the enzymatic hydrolysis process, it is very important to maintain acid-base balance and temperature environment stability, because enzymes are high-molecular substances with biocatalytic functions, and their activity is affected by the environmental pH value and temperature.

[0058] During this process, the heater in the reaction box 1 heats the American ginseng crushed material in the reaction box 1 to maintain a stable temperature environment in the reaction box 1, and at the same time, the heater in the liquid storage tank 2 heats the alkaline solution in the liquid storage tank 2 to prevent the alkaline solution in the liquid storage tank 2 from entering the reaction box 1 and affecting the temperature environment in the reaction box 1;

[0062] like Figure 8 As shown, an enzymatic hydrolysis device for preparing American ginseng provided by the present invention, the liquid mixing mechanism 3 includes a motor 31, a rotating shaft 32, a rotating tube 33 and a solenoid valve 34;

[0063] A motor 31 is fixedly connected to the upper end surface of the liquid storage tank 2, and an output shaft of the motor 31 is fixedly connected to a rotating shaft 32. One end of the rotating shaft 32 passes through the interior of the reaction box 1. The rotating shaft 32 is connected to a plurality of rotating tubes 33, and each rotating tube 33 is provided with an electromagnetic valve 34. All support frames 4 are fixedly connected to the rotating shaft 32, and the inner cavities of all support frames 4 are connected to the rotating shaft 32.

[0066] The ends of the support frame 4 are rotatably connected to gear sleeves 51, and the gear sleeves 51 are vertically slidably connected to connecting rods 52. All connecting rods 52 are of different lengths. A plurality of stirring rods 55 are fixedly connected to the lower ends of the connecting rods 52. A boss is provided at the upper end of the connecting rod 52. A spring 53 is provided between the boss at the upper end of the connecting rod 52 and the gear sleeve 51. A gear ring 54 is fixedly connected to the inner wall of the reaction box 1. All gear sleeves 51 are meshed with the gear ring 54.

Under the transmission action of the transmission assembly 56, the connecting rod 52 can vibrate vertically reciprocatingly, and the stirring rod 55 is connected with a guide hole 14.

[0067] In this embodiment, when the rotating shaft 32 rotates, the rotating shaft 32 drives all the supporting frames 4 to rotate, and all the supporting frames 4 respectively drive the connected connecting rods 52 to perform circular motion around the rotating shaft 32. At this time, under the guidance of the ring gear 54, the gear sleeve 51 drives the connecting rod 52 to rotate relative to the supporting frame 4, and the connecting rod 52 drives the stirring rod 55 to mix and stir the mixed material in the reaction box 1.

[0071] In this embodiment, the rotating tube 33 is connected to the rotating shaft 32, the rotating shaft 32 is connected to the inner cavity of the support frame 4, and the support frame 4 is connected to the connecting rod 52 through the hard conduit 61 and the rubber tube 62, so that the alkaline solution in the liquid storage tank 2 can be added to the reaction box 1 through the guide hole 14 on the stirring rod 55. Since the stirring rods 55 on each connecting rod 52 are distributed at different heights in different areas of the reaction box 1, the stirring rod 55 can stir the mixture in the reaction box 1 more evenly. At the same time, the guide hole 14 on the stirring rod 55 can adjust the pH of the mixture in the entire reaction box 1 more quickly when adding it to the reaction box 1.

[0073] In this embodiment, the rotating shaft 32 drives the pushing blade 72 to rotate, and the pushing blade 72 drives the mixed material at the bottom of the outer jacket 71 to be transported upward. The mixed material is evenly dispersed around the outer jacket 71 through the material guiding mechanism 8, which can avoid sedimentation and accumulation at the bottom of the reaction box 1.

When the mixed material in the outer sleeve 71 is pushed upward, the mixed material is transported to the outside through the discharge port 85 on the cover plate 82. When the cover plate 82 rotates, the mixed material is evenly sprayed from the cover plate 82 in different directions.

[0077] When the electric telescopic sleeve 81 is extended and retracted, the electric telescopic sleeve 81 drives the cover plate 82 to move vertically upward or downward.
