Description

Technical Field

[0001] This utility model relates to the field of anthocyanin extraction technology, and in particular to a device for extracting anthocyanins from purple sweet potatoes. Background Technology

[0002] In today's food, medicine and cosmetic fields, anthocyanins, as a natural pigment with excellent antioxidant, anti-inflammatory and cardiovascular disease prevention effects, are in increasing demand. Purple sweet potatoes are rich in anthocyanins and have become a high-quality source of raw materials for anthocyanin extraction.

[0003] Most existing purple sweet potato anthocyanin extraction devices use a stirring-type crushing device. This device relies on a motor to drive a stirring blade to rotate at high speed within the container holding the purple sweet potato to crush it. However, the cell walls of purple sweet potatoes are tough, and simple stirring cannot achieve deep crushing. As a result, many cells cannot be fully broken down, making it difficult to release anthocyanins from the cells. Even with the addition of sufficient extraction agent, the dissolution rate remains limited, ultimately leading to a low extraction rate. The entire process is time-consuming and energy-intensive, significantly increasing production costs. Therefore, improvements are needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for extracting anthocyanins from purple sweet potatoes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a device for extracting anthocyanins from purple sweet potatoes, comprising a crushing and twisting box, an addition box on one side of the crushing and twisting box, a discharge pump on the crushing and twisting box, a dosing pipe between the discharge pump and the addition box, a collection pipe connected to the bottom surface of the crushing and twisting box, a collection box connected to the end of the collection pipe, the collection box located on the other side of the crushing and twisting box, a box cover on the top surface of the crushing and twisting box by fixing bolts, a feed inlet on the box cover, and two drive motors symmetrically installed on both sides of the top of the crushing and twisting box, the output shafts of the two drive motors being connected to an extrusion assembly.

[0006] Preferably, the extrusion assembly includes a connecting plate with one end fixed to the output shafts of the two drive motors, and there are two connecting plates. The swing crank is rotatably arranged between the opposite faces of the other ends of the two connecting plates. The middle section of the swing crank is through which the pressure block is inserted, and the filter cylinder is sleeved on the outer side of the pressure block.

[0007] Preferably, a plurality of bolt buckles are evenly distributed around the top surface of the filter cylinder, and the filter screen is snapped onto the plurality of bolt buckles, with the filter screen sleeved on the outer wall of the filter cylinder.

[0008] Preferably, the compression crushing box is provided with a mounting plate at the center of the bottom surface of the filter screen, the motor box is fixedly connected to the mounting plate, and the mixing and crushing blade is fixedly connected to the output shaft of the motor box.

[0009] Preferably, the bottom end of the compression crushing box is funnel-shaped.

[0010] Preferably, two threaded mounting rods extend from both sides of the outer wall of the filter cylinder, and both threaded mounting rods penetrate the filter screen and abut against the inner wall of the compression crushing box. Fixing bolts corresponding to the two threaded mounting rods are provided on the outer wall of the compression crushing box.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the cooperation of a drive motor with a connecting plate, a swinging crank, a pressing block, and a filter cylinder, enables the drive motor to drive the connecting plate to move, causing the swinging crank to swing, which in turn drives the pressing block and the filter cylinder to perform multi-angle, high-intensity pressing and twisting of the purple sweet potato. This facilitates the full destruction of the purple sweet potato cell structure, improves the cell breaking effect and anthocyanin release efficiency, and thus achieves the function of efficient anthocyanin release. Furthermore, through the cooperation of a liquid discharge pump with an addition tank and a dosing pipeline, the liquid discharge pump precisely controls the amount of extractant added from the addition tank to the pressing and twisting crushing tank through the dosing pipeline, facilitating the full reaction of the extractant with the purple sweet potato, improving the utilization efficiency of the extractant and the dissolution efficiency of anthocyanins. Ultimately, this solves the problem of low anthocyanin extraction rate caused by the inability of existing stirring crushing devices to deeply crush purple sweet potatoes, significantly improving extraction efficiency and economic benefits.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: See Figure 1-4This utility model discloses a device for extracting anthocyanins from purple sweet potatoes, comprising a crushing and twisting chamber 1, an addition box 2 on one side of the crushing and twisting chamber 1, a discharge pump 3 on the crushing and twisting chamber 1, a dosing pipe between the discharge pump 3 and the addition box 2, a collection pipe connected to the bottom of the crushing and twisting chamber 1, a collection box 4 connected to the end of the collection pipe, the collection box 4 located on the other side of the crushing and twisting chamber 1, a cover on the top surface of the crushing and twisting chamber 1 secured by bolts, a feed inlet on the cover, and two drive motors 5 symmetrically mounted on both sides of the top of the crushing and twisting chamber 1, the output shafts of the two drive motors 5 connected to... The device is equipped with an extrusion assembly, forming the overall architecture of the anthocyanin extraction unit. The various components work together to provide a foundation for subsequent extraction, facilitating material addition, processing, and collection, thus improving operational convenience. The crushing and twisting box 1 is made of 304 stainless steel, possessing good structural strength and corrosion resistance, ensuring stable operation and extending service life during long-term use. The drive motor 5 is a Y2 series three-phase asynchronous motor, characterized by high efficiency, energy saving, and stable operation, providing stable and reliable power to the extrusion assembly. The extrusion assembly includes one end fixed to two... Two connecting plates are mounted on the output shaft of a drive motor 5. A swing crank 6 is rotatably mounted between the opposite faces of the two connecting plates. A pressure block 7 passes through the middle section of the swing crank 6, and a filter cylinder 8 is sleeved on the outer side of the pressure block 7. The drive motor 5 drives the connecting plates, swing crank 6, pressure block 7, and filter cylinder 8 to move, effectively squeezing and crushing the purple sweet potatoes. Compared to traditional stirring-type crushing devices, this method can more deeply destroy the cell structure of the purple sweet potatoes, improving the release efficiency of anthocyanins. The filter cylinder 8 is made of stainless steel, possessing good rigidity and corrosion resistance, and can remain stable during squeezing and filtering. To ensure long-term stable operation, multiple bolt clips 11 are evenly distributed around the top surface of the filter cylinder 8, and filter screens 9 are snapped onto these bolt clips 11. The filter screens 9 are fitted onto the outer wall of the filter cylinder 8. The bolt clips 11 secure the filter screens 9, facilitating their installation and removal, cleaning, and replacement, ensuring filtration efficiency, and preventing purple sweet potato residue from mixing into the extract. The filter screens 9 are made of nylon, which has good wear resistance and corrosion resistance, high filtration accuracy, and can effectively separate purple sweet potato residue from the extract, while maintaining stable filtration performance even with frequent use.

[0020] In this invention, a mounting plate is located at the center of the bottom surface of the filter screen 9 in the compression crushing box 1. A motor housing 13 is fixedly mounted on the mounting plate, and a mixing crushing blade 12 is fixedly mounted on the output shaft of the motor housing 13. The motor housing 13 drives the mixing crushing blade 12 to rotate, further crushing and mixing the purple sweet potato after compression and preliminary filtration, so that the purple sweet potato and the extractant can fully contact each other, improving the dissolution rate of anthocyanins. The mixing crushing blade 12 is made of high-speed steel, which has high hardness and good wear resistance, and can efficiently crush and mix the purple sweet potato under high-speed rotation, ensuring the crushing effect while extending the service life of the blade. The bottom of the compression crushing box 1 is funnel-shaped. The funnel-shaped design facilitates the flow of materials to the collection pipe, improves the material collection efficiency, and reduces the residue of materials in the compression crushing box 1. The compression crushing box 1 is made of stainless steel 3. The material, with its funnel-shaped design, offers excellent corrosion resistance, ensuring the equipment remains unaffected by material flow and maintaining stable material guidance. Two threaded mounting rods 10 extend from both sides of the outer wall of the filter cylinder 8, penetrating the filter screen 9 and abutting against the inner wall of the crushing and twisting chamber 1. The outer wall of the crushing and twisting chamber 1 is equipped with fixing bolts corresponding to the two threaded mounting rods 10. The threaded mounting rods 10 and fixing bolts secure the filter cylinder 8 and filter screen 9 within the crushing and twisting chamber 1, ensuring the stability of the filtration structure and preventing shaking and displacement during operation, which would affect the filtration effect. The threaded mounting rods 10 can be made of carbon steel with surface rust prevention treatment, possessing good strength and fastening performance, stably fixing the filter components within the crushing and twisting chamber 1 and ensuring normal equipment operation.

[0021] Working Principle: In the use of this utility model, purple sweet potatoes are first fed into the crushing and twisting box 1 through the inlet on the box cover. Simultaneously, an appropriate amount of extractant is prepared in the addition box 2 according to the extraction process requirements. The discharge pump 3 is on standby. Then, the drive motors 5 on both sides of the top of the crushing and twisting box 1 are started. The Y2 series three-phase asynchronous motors provide power. The output shaft of the drive motor 5 drives the connecting plate, which causes the swinging crank 6 to swing. The pressure block 7, which passes through the middle section of the swinging crank 6, squeezes the purple sweet potato at multiple angles within the filter cylinder 8, gradually destroying the cell structure and initially releasing anthocyanins. Next, the discharge pump 3 is started, and the addition box 2... The extractant is precisely delivered to the crushing and twisting chamber 1 via the dosing pipe. At this time, the motor box 13 located at the center of the bottom surface of the filter screen 9 operates, and its output shaft drives the mixing and crushing blades 12 to rotate at high speed, crushing the compressed purple sweet potato again and mixing it thoroughly with the extractant to promote the dissolution of anthocyanins. During the mixing and crushing process, the extract containing anthocyanins and the purple sweet potato residue flow downwards together. The filter screen 9, which is fitted on the outer wall of the filter cylinder 8, intercepts the purple sweet potato residue, allowing only the extract to pass through. Finally, the bottom of the crushing and twisting chamber 1 is funnel-shaped, which facilitates the extraction of the extract to flow into the collection box 4 along the collection pipe, completing the collection. At this point, the device is in use.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
