Description

Technical Field

[0001] This utility model relates to the field of Nisin embedding equipment technology, and in particular to an embedding device used in the Nisin preparation process. Background Technology

[0002] As is well known, nisin, also known as lactic acid nisin peptide, is a polypeptide produced by *Streptococcus lactis*, composed of 34 amino acid residues with a molecular weight of approximately 3500 Da. Because nisin can inhibit most Gram-positive bacteria and has a strong inhibitory effect on Bacillus spores, it is widely used as a food preservative in the food industry. After consumption, it is rapidly hydrolyzed into amino acids under the physiological pH conditions of the human body and the action of α-chymotrypsin. It does not alter the normal flora in the human gut or cause resistance problems as seen with other antibiotics, nor does it exhibit cross-resistance with other antibiotics. It is a highly effective, non-toxic, safe, and side-effect-free natural food preservative.

[0003] However, the biological activity of Nisin is often lost due to interactions with certain components in food (such as proteins, lipids, and metabolic enzymes), severely affecting its efficacy. To prolong the preservative effect time and improve the stability of Nisin, it is often necessary to encapsulate it. Encapsulated Nisin can be slowly released and its antibacterial time can be prolonged. In the prior art, patent publication number CN 109173946 B, "Sodium Alginate Chitosan Microcapsules Containing Polylysine and Nisin and Their Preparation," discloses an encapsulation technique for Nisin. However, this method encapsulates Nisin through a chemical method, which is relatively complex and requires high process control. Moreover, it cannot achieve continuous encapsulation production of Nisin. Utility Model Content

[0004] To overcome the shortcomings of the prior art, this utility model discloses an embedding device for the preparation of Nisin. This utility model melts the embedding agent through a feeding mechanism and transports the melted embedding agent to a stirring mechanism. A filling mechanism evenly sprinkles Nisin into the stirring mechanism, which then uniformly stirs the liquid embedding agent and Nisin, causing the embedding agent to encapsulate the Nisin. A conveying mechanism transports the mixed liquid, and during this process, the embedding agent is cooled to solidify the Nisin-encapsulated embedding agent, facilitating collection by personnel.

[0028] The aforementioned embedding device for the preparation of stable Nisin involves the operator pulling a closing plate 410 to detach it from the packing box 406, placing the embedding agent onto the placement plate 407 within the packing box 406. Xylitol or acrylic resin is preferred as the embedding agent; xylitol has a melting point of 92-96℃, and acrylic resin has a melting point of 95℃. After placement, the closing plate 410 is reset, which moves the entire telescopic rod 409, causing the moving plate 408 to detach from the placement plate 407. The power switch group 2 activates the heating wires and servo motor 405 within the placement plate 407, feeding pipe 402, mixing tank 705, and moving plate 408. The heating wires on the placement plate 407 and moving plate 408 heat the embedding agent to 93-95℃, causing it to melt and encapsulate. After the embedding agent melts into a liquid, it enters the feeding pipe 402. The servo motor 405 drives the auger blades 404 to rotate via the rotating rod 403.

During rotation, the first bevel gear 306 rotates, which in turn drives the push plate 309 to rotate via the second bevel gear 307. The push plate 309 then moves the material distribution box 303. A spring 304 resets the material distribution box 303, causing it to shake and evenly distribute Nisin into the mixing tank 705. The power switch group 2 starts the drive motor 708, which, via the rotating rod 707, drives the stirring blades 706 to rotate. The stirring blades 706 then move the mixing tank... The two substances in 705 are mixed together. The electric telescopic rod 702 is activated by the power switch group 2. The electric telescopic rod 702 moves the blockage block through the transmission rod 704, causing the blockage block to detach from the mixing tank 705. The mixed embedding agent in the mixing tank 705 falls onto the conveyor belt 504. The delivery pump is activated by the power switch group 2, and the delivery pump delivers the condensate in the liquid tank 502 to the condenser pipe 503. The condenser pipe 503 cools the embedding agent on the conveyor belt 504, causing the Nisin embedding agent to solidify, making it easy for the staff to remove.
