Description

Technical Field

[0001] This utility model relates to the field of centrifugation equipment, and in particular to a centrifugation device for separating prickly pear enzyme liquid. Background Technology

[0002] As a natural product rich in nutrients, prickly pear enzyme liquid has broad application prospects in food, health products, and cosmetics. However, prickly pear enzyme liquid usually contains a high amount of pectin, which increases the viscosity of the liquid and affects subsequent processing and application. Therefore, how to efficiently hydrolyze pectin and separate impurities has become a key issue in the processing of prickly pear enzyme liquid.

[0003] Currently, the commonly used methods for processing prickly pear enzyme solution on the market mainly rely on traditional enzymatic hydrolysis and separation processes. During enzymatic hydrolysis, the lack of efficient mixing equipment results in low mixing efficiency between pectinase and prickly pear enzyme solution, leading to a long hydrolysis time (usually 1-2 hours). This not only reduces production efficiency but also increases equipment operating time and energy consumption, raising production costs. Furthermore, during separation, the presence of oxygen easily causes oxidation of polyphenols in the prickly pear enzyme solution, leading to the loss of active ingredients and affecting product stability and quality.

[0004] The technical problem to be solved by this application is: a centrifugal device for separating prickly pear enzyme liquid, which can shorten the hydrolysis time, improve the mixing efficiency, and effectively prevent oxidation, so as to meet the needs of efficient treatment and high-quality processing of prickly pear enzyme liquid. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a centrifuge device for separating prickly pear enzyme liquid. In the treatment of prickly pear enzyme liquid, 0.2%-0.5% pectinase is added and mixed by a static mixer, which reduces the hydrolysis time from 1-2 hours to 20 minutes, thereby reducing costs and increasing efficiency. During centrifugation, nitrogen is used to replace oxygen, preventing oxidation, preserving nutrients and active ingredients, and improving product quality and competitiveness.

[0006] The technical solution adopted by this utility model is as follows: a centrifuge for separating prickly pear enzyme liquid, including a feed pipe, an injection pipe fixedly connected to the upper left side of the feed pipe, a static mixer provided on the inner wall of the feed pipe, a one-way valve fixedly connected to the middle of the feed pipe, a nitrogen cylinder provided to the right of the one-way valve, a vertical shaft rotatably connected to the lower right side of the feed pipe, a housing rotatably connected to the outer wall of the vertical shaft, a discharge pipe fixedly connected to the upper right side of the housing, a suction pump fixedly connected to the middle of the discharge pipe, a disc assembly connected inside the housing via a rotating component, a rotating shaft rotatably connected to the bottom of the housing, and a motor fixedly connected to the lower end of the rotating shaft.

[0007] In some embodiments, the rotating assembly includes a drum disposed inside the housing, the lower end of the drum having a slag discharge port, a large piston being slidably connected to the inner side of the slag discharge port, and the outer wall of the disc assembly being disposed inside the drum.

[0008] In some embodiments, the upper end of the drum is fixedly connected to the outer wall of the vertical shaft, and the bottom end of the large piston is fixedly connected to the outer wall of the shaft.

[0009] In some embodiments, a slag discharge pipe is fixedly connected to the lower end of the casing, and a bracket is fixedly connected to the outer wall of the casing.

[0010] In some embodiments, a water inlet pipe is provided at the upper end of the slag discharge pipe, and the left end of the water inlet pipe is fixedly connected to the right side of the lower end of the machine casing.

[0011] In some embodiments, the bottom end of the nitrogen cylinder is fixedly connected to the top end of the bracket, and the non-driving end of the motor is fixedly connected to the bottom end of the bracket.

[0012] In some embodiments, a drain pipe is fixedly connected to the lower right side of the housing, and the top of the rotating shaft is fixedly connected to the bottom of the disc assembly.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. By adding 0.2%-0.5% pectinase to the prickly pear enzyme solution and combining it with the rapid and uniform mixing function of a static mixer, the hydrolysis process, which originally required 1-2 hours, was shortened to 20 minutes. This highly efficient hydrolysis method not only significantly improves production efficiency but also reduces equipment operating time, lowers energy consumption and production costs, making the process more economical and efficient.

[0015] 2. During centrifugation, nitrogen gas is introduced into the disc centrifuge to effectively replace oxygen, thereby preventing the oxidation of polyphenols and other active ingredients. This antioxidant measure not only preserves the nutrients and bioactive components in the prickly pear enzyme liquid but also improves the product's stability and quality, laying a solid foundation for subsequent deep processing and applications, and enhancing the product's market competitiveness.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a centrifugal device for separating prickly pear enzyme liquid, including a feed pipe 1, an injection pipe 2 fixedly connected to the upper left side of the feed pipe 1, a static mixer 3 provided on the inner wall of the feed pipe 1, a one-way valve 4 fixedly connected to the middle end of the feed pipe 1, and a nitrogen cylinder 5 provided on the right side of the one-way valve 4.

[0023] Specifically, when operating this device to process prickly pear enzyme solution, the solution is first introduced into the device via the feed pipe 1. Simultaneously, pectinase is added to the solution through the injection pipe 2, at a rate of 0.2%-0.5% of the total solution volume. The pectinase breaks down the pectin components in the solution, thereby reducing its viscosity. Subsequently, the mixture of prickly pear enzyme solution and pectinase enters the static mixer 3. Within the static mixer 3, the two are quickly and uniformly mixed. Thanks to this uniform mixing, the hydrolysis process, which originally required 1-2 hours, can now be completed in just 20 minutes.

[0024] At the start of centrifugation, nitrogen gas is introduced into the disc centrifuge from nitrogen cylinder 5. The introduction of nitrogen gas replaces the oxygen in the disc centrifuge, effectively preventing the oxidation of polyphenols in the prickly pear enzyme solution.

[0025] See Figure 1 , Figure 3 and Figure 4A vertical shaft 6 is rotatably connected to the lower right side of the feed pipe 1. A housing 9 is rotatably connected to the outer wall of the vertical shaft 6. A discharge pipe 8 is fixedly connected to the upper right side of the housing 9. A suction pump 7 is fixedly connected to the middle of the discharge pipe 8. A rotating drum 11 is located inside the housing 9. The upper end of the rotating drum 11 is fixedly connected to the outer wall of the vertical shaft 6. A slag discharge port 12 is opened at the lower end of the rotating drum 11. A large piston 13 is slidably connected to the inner side of the slag discharge port 12. The outer wall of the disc assembly 14 is located inside the rotating drum 11. A rotating shaft 19 is rotatably connected to the bottom end of the housing 9. A large piston 13 is fixedly connected to the lower end of the housing 9. A slag discharge pipe 17 is connected, and a water inlet pipe 15 is provided at the upper end of the slag discharge pipe 17. The left end of the water inlet pipe 15 is fixedly connected to the lower right side of the housing 9. The bottom end of the large piston 13 is fixedly connected to the outer wall of the rotating shaft 19. A motor 18 is fixedly connected to the lower end of the rotating shaft 19. A bracket 10 is fixedly connected to the outer wall of the housing 9. A drain pipe 16 is fixedly connected to the lower right side of the housing 9. The top end of the rotating shaft 19 is fixedly connected to the bottom end of the disc assembly 14. The bottom end of the nitrogen cylinder 5 is fixedly connected to the top end of the bracket 10. The non-drive end of the motor 18 is fixedly connected to the lower end of the bracket 10.

[0026] Specifically, before feeding the prickly pear enzyme solution into the disc centrifuge, sealing water needs to be introduced into the device through the water inlet pipe 15. The purpose of the sealing water is to push the large piston 13 upward, sealing the slag discharge port 12, preparing for the subsequent centrifugation operation. After the prickly pear enzyme solution enters the disc centrifuge and completes hydrolysis, the motor 18 is started. The drive end of the motor 18 drives the rotating shaft 19 to rotate, which in turn drives the disc assembly 14, the rotating drum 11, and the vertical shaft 6 to rotate together. After centrifugation, solid impurities will accumulate at the junction of the large piston 13 and the rotating drum 11. The prickly pear enzyme solution will then converge upward along the holes at the top and bottom of the disc assembly 14. Afterward, the prickly pear enzyme solution is extracted from the discharge pipe 8 using the suction pump 7. After the centrifugation operation continues for a period of time, the sealing water is discharged through the drain pipe 16. As the sealing water is discharged, the large piston 13 descends, the slag discharge port 12 is exposed, and the solid impurities are discharged, finally exiting the device through the slag discharge pipe 17.

[0027] The working principle and usage process of this utility model are as follows: When using this device, prickly pear enzyme liquid is input through the feed pipe 1, and pectinase dosage of 0.2%-0.5% is injected through the injection pipe 2 to decompose the pectin in the prickly pear enzyme liquid and reduce its viscosity. It is then quickly and evenly mixed through the static mixer 3, and then fed into the disc centrifuge through the one-way valve 4. Due to the uniform mixing by the static mixer 3, the hydrolysis time, which was originally 1-2 hours, is now shortened to 20 minutes. Before the prickly pear enzyme liquid enters the disc centrifuge, sealing water is input through the water inlet pipe 15, which pushes the large piston 13 upwards, sealing the slag discharge port 12. The prickly pear enzyme liquid then enters the disc centrifuge... After the hydrolysis is completed, the motor 18 is started. The drive end of the motor 18 drives the rotating shaft 19 to rotate, and the rotating shaft 19 drives the disc assembly 14 to rotate. The drum 11 and the vertical shaft 6 rotate accordingly. Nitrogen gas is then introduced into the disc centrifuge through the nitrogen cylinder 5. The nitrogen gas replaces the oxygen and prevents the polyphenols from oxidizing. After centrifugation, solid impurities gather at the junction of the large piston 13 and the drum 11. The prickly pear enzyme liquid gathers upward along the holes at the top and bottom of the disc assembly 14 and is drawn out from the discharge pipe 8 by the suction pump 7. After centrifugation for a period of time, the sealing water is discharged through the drain pipe 16, causing the large piston 13 to descend and expose the slag discharge port 12 to discharge the solid impurities. Finally, the solid impurities are discharged through the slag discharge pipe 17.
