[0033] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] Embodiment 1, as Figure 1-Figure 7As shown, a device for preparing a stock solution of a food protein preservative comprises a conical reaction tank 1, a feed pipe 2 is fixed inside the upper end of the conical reaction tank 1, a fixed plate 3 located inside the conical reaction tank 1 is fixedly sleeved at the lower end of the feed pipe 2, a trumpet tube 4 is fixed at the bottom of the fixed plate 3, a driving motor 6 is fixed at the top of the conical reaction tank 1, a rotating rod 7 is transmission-connected to the lower end of the driving motor 6, the lower end of the rotating rod 7 passes through the conical reaction tank 1 and is fixedly connected to a spiral rod 8 located inside the trumpet tube 4, a side opening 5 is opened at the upper end of the trumpet tube 4, a bottom opening 11 is opened at the lower end of the conical reaction tank 1, a conical disk 25 for closing the bottom opening 11 is movably sleeved inside the conical reaction tank 1, a side groove cylinder 10 is fixedly sleeved inside the conical disk 25, a limiting sleeve is connected to a limiting rod 9 inside the side groove cylinder 10, the upper end of the limiting rod 9 is fixedly connected to the spiral rod 8, and the gap between the trumpet tube 4 and the conical disk 25 gradually decreases from bottom to top.

[0035] When in use, ascorbic acid, bioflavonoids, oleuropein and glucoside are sequentially fed into the citrate buffer solution inside the conical reaction tank 1 through the feed pipe 2. At this time, the drive motor 6 is started, so that the rotating rod 7 drives the spiral rod 8 to rotate along the inner wall of the trumpet tube 4, so that the spiral rod 8 spirally transports the citrate buffer solution etc. inside the trumpet tube 4 upward, and then the citrate buffer solution is discharged from the top of the citrate buffer solution inside the conical reaction tank 1 through the side port 5, so that the citrate buffer solution raw materials etc. inside the conical reaction tank 1 enter the trumpet tube 4 again through the gap between the conical disk 25 and the trumpet tube 4, and are circularly spirally transported by the spiral rod 8, avoiding This prevents ascorbic acid, bioflavonoids, oleuropein and glucoside from being precipitated at the bottom of the conical reaction tank 1. At the same time, the spiral rod 8 drives the conical disk 25 to rotate through the limiting rod 9 and the side groove cylinder 10, so that the conical disk 25 can rotate and grind the ascorbic acid, bioflavonoids, oleuropein and glucoside and other raw materials agglomerates between the conical disk 25 and the trumpet tube 4, so that the polished ascorbic acid, bioflavonoids, oleuropein and glucoside and other raw materials can react more fully with the citrate buffer solution, thereby preventing the ascorbic acid, bioflavonoids, oleuropein and glucoside raw materials from precipitating or agglomerating and failing to react fully, affecting the effect of preparing the food protein preservative preservative stock solution.

[0036] Embodiment 2, as Figure 1-Figure 3 As shown, a controller 26 is fixedly installed on the outer surface of the conical reaction tank 1, and a heating block 12 is fixedly installed inside the conical reaction tank 1. The controller 26 is electrically connected to the heating block 12 and the driving motor 6 respectively.

[0037] Through the mutual cooperation between the controller 26, the heating block 12 and the driving motor 6, the controller 26 can start the heating block 12 and the driving motor 6, so that the heating block 12 heats the prepared food protein preservative solution inside the conical reaction tank 1 to ten degrees Celsius, thereby making the circulation reaction effect of the prepared food protein preservative solution inside the conical reaction tank 1 better.

[0038] Embodiment three, as Figure 1 As shown, a fixing frame 27 is fixed to the outer surface of the conical reaction tank 1 , and support rods 28 are fixed to the bottom of the fixing frame 27 in an annular manner and at equal intervals.

[0039] Through the design of the support rods 28 and the fixing frame 27, the support rods 28 and the fixing frame 27 can stably support the entire conical reaction tank 1, and the entire conical reaction tank 1 is kept at a distance from the ground. Therefore, when the entire conical reaction tank 1 is in use, the food protein preservative concentrate inside the conical reaction tank 1 is discharged through the bottom port 11 into a collection tank placed between the support rods 28 for subsequent use.

[0040] Embodiment 4, as Figure 2-Figure 5 As shown, the conical disk 25 is internally movably sleeved with a first convex disk 13, the top of the first convex disk 13 is movably connected to the bottom of the side groove cylinder 10, a connecting rod 14 is fixed to the lower end of the first convex disk 13, the other end of the connecting rod 14 is connected to an electric telescopic rod 15, the electric telescopic rod 15 is fixedly installed at the bottom of the conical reaction tank 1, and the electric telescopic rod 15 is electrically connected to the controller 26.

[0041] The electric telescopic rod 15 is started by the controller 26, so that the connecting rod 14 pushes the side groove cylinder 10 to move upward along the outer surface of the limit rod 9 through the first convex disk 13, and then the side groove cylinder 10 drives the conical disk 25 to move upward to open the bottom opening 11, so that the food protein preservative liquid inside the conical reaction tank 1 is discharged through the bottom opening 11, thereby achieving the purpose of facilitating the opening of the bottom opening 11 to discharge the food protein preservative liquid.

[0042] Embodiment 5, as Figure 3-Figure 7 As shown, the internal limiting sleeve of the fixed disk 3 is connected with a circular ring block 20, the bottom of the circular ring block 20 is fixed with a gear ring 19, the bottom of the circular ring block 20 is fixedly connected with a spiral leaf 21, and the spiral leaf 21 is in close contact with the outer surface of the trumpet tube 4 and the inner wall of the conical reaction tank 1 respectively.

[0043] When the gear ring 19 rotates, the circular ring block 20 drives the spiral blade 21 to rotate along the outer surface of the trumpet tube 4 and the inner wall of the conical reaction tank 1, so that the spiral blade 21 scrapes off the raw materials such as ascorbic acid, bioflavonoids, oleuropein and glucoside that are adhered to the outer surface of the trumpet tube 4 and the inner wall of the conical reaction tank 1, thereby achieving the purpose of preventing the raw materials such as ascorbic acid, bioflavonoids, oleuropein and glucoside from adhering to the inner wall of the conical reaction tank 1.

[0044] Embodiment six, as Figure 4-Figure 6 As shown, the inner limit sleeve of the upper end of the conical reaction tank 1 is connected with a second convex disk 16, the lower end of the second convex disk 16 is fixed with a first gear 17, the outer surface of the first gear 17 is meshingly connected with the outer surface of the gear ring 19, the outer surface of the first gear 17 is meshingly connected with a second gear 18, and the inner wall of the second gear 18 is fixedly sleeved with the outer surface of the rotating rod 7.

[0045] When the driving motor 6 drives the second gear 18 to rotate through the rotating rod 7, the second gear 18 drives the gear ring 19 to rotate through the first gear 17, and the second convex disk 16 rotates along the inner wall of the conical reaction tank 1 to limit the first gear 17, so that the spiral rod 8 transports the food protein preservative solution inside the bell tube 4 to the side port 5 and discharges it onto the spiral blade 21, and at the same time, the annular block 20 drives the spiral blade 21 to rotate to transport the food protein preservative solution inside the conical reaction tank 1 to the gap between the conical disk 25 and the limiting rod 9, and the food protein preservative solution transported by the spiral blade 21 will wash away the sticky raw materials scraped off by the spiral blade 21, so that the sticky raw materials are circulated and mixed between the conical disk 25 and the bell tube 4.

[0046] Embodiment seven, as Figure 7 As shown, a top groove 22 is provided inside the upper end of the conical reaction tank 1 , and the top groove 22 corresponds to the gear ring 19 .

[0047] Through the design of the top groove 22 and the gear ring 19, when the conical disk 25 and the bell tube 4 are blocked by raw material lumps that cannot be quickly crushed, the spiral blades 21 cannot push the liquid inside the conical reaction tank 1 to flow between the conical disk 25 and the bell tube 4, so that the hydraulic pressure at the lower end of the conical reaction tank 1 gradually increases, and the liquid squeezes the rotating spiral blades 21 to move upward, so that the spiral blades 21 drive the gear ring 19 to move into the top groove 22 through the circular ring block 20, and the gear ring 19 is disengaged from the first gear 17, so that the second gear 18 cannot drive the gear ring 19 to rotate through the first gear 17, so that the spiral blades 21 will not be deformed and damaged by hydraulic squeezing due to excessive pressure in the downward transportation of the food protein preservative concentrate.

[0048] Embodiment eight, as Figure 6-Figure 7 As shown, a push rod 23 is movably sleeved in an inner annular equidistant manner at the upper end of the conical reaction tank 1, and the lower end of the push rod 23 is in extrusion contact with the top of the gear ring 19. A rigid spring 24 is fixed to the bottom of the upper end of the push rod 23, and the bottom of the rigid spring 24 is fixedly connected to the top of the conical reaction tank 1.

[0049] By squeezing the gear ring 19 with the rigid spring 24 and the push rod 23, when the gear ring 19 drives the spiral blade 21 to spirally push the food protein preservative and fresh-keeping agent liquid downward through the circular ring block 20, the gear ring 19 will not be pushed away from the first gear 17 by a slight water pressure. Only when the water pressure is about to squeeze the spiral blade 21 to deform and damage it, the gear ring 19 will push the push rod 23 to stretch the rigid spring 24, move into the top groove 22, and release the meshing relationship with the first gear 17.

[0050] A method for preparing a food protein preservative stock solution, such as Figure 1-Figure 7 As shown, the following steps are included:

[0051] S1, feeding ascorbic acid, bioflavonoids, oleuropein and glucoside into the citrate buffer solution in the conical reaction tank 1 in sequence through the feeding tube 2;

[0052] S2, starting the heating block 12 through the controller 26, so that the heating block 12 heats the mixed solution of ascorbic acid, bioflavonoids, oleuropein and glucoside and citrate buffer solution in the conical reaction tank 1 to ten degrees Celsius;

[0053] S3, the controller 26 controls the driving motor 6 to start, so that the spiral rod 8 and the spiral blade 21 rotate to circulate and transport the mixed liquid inside the conical reaction tank 1, and the conical disk 25 rotates to grind the mixed raw material agglomerates between the conical disk 25 and the horn tube 4, and at the same time, the spiral blade 21 will scrape off the mixed raw materials adhering to the outer surface of the horn tube 4 and the inner wall of the conical reaction tank 1, and be washed by the mixed liquid for cyclic mixing reaction, and after continuous stirring for two hours, it is left to stand for forty-eight hours to obtain the stock solution;

[0054] S4. The electric telescopic rod 15 is started by the controller 26, so that the connecting rod 14 pushes the conical disk 25 through the first convex disk 13 and the side groove cylinder 10 to open the bottom opening 11, so that the food protein preservative stock solution inside the conical reaction tank 1 is discharged through the bottom opening 11, and then the stock solution is discharged into the collection tank placed between the support rods 28.

[0055] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
