Description

Technical Field

[0001] This utility model relates to the field of edible fungi processing technology, specifically to a device for extracting polysaccharides from Auricularia auricula-judae based on dynamic water. Background Technology

[0002] Golden ear fungus polysaccharide is a bioactive high-molecular-weight polysaccharide extracted from the rare edible and medicinal fungus Golden Ear Fungus. It is one of the most important functional components of Golden Ear Fungus. Golden Ear Fungus polysaccharide has a complex molecular structure and various biological activities, which have many benefits for human health, such as enhancing immunity, anti-oxidation and anti-aging, regulating blood lipids and blood sugar, and moisturizing the lungs and protecting the throat.

[0003] Traditional methods for extracting polysaccharides from Auricularia auricula-judae mainly employ static extraction processes, such as hot water extraction. These methods generally suffer from low extraction efficiency and long extraction times. In particular, under static conditions, Auricularia auricula-judae tends to clump and sink after soaking in water, resulting in a small contact area between the auricularia auricula-judae and water, which slows down the polysaccharide dissolution rate and seriously affects the water extraction effect. Subsequent methods using stirring extraction of Auricularia auricula-judae material are also problematic because Auricularia auricula-judae is fragile when it comes into contact with water and tends to form a paste after stirring. This makes it difficult to separate the auricularia auricula-judae polysaccharide solution from the auricularia auricula-judae residue in the later stages, which seriously affects the extraction quality. Utility Model Content

[0004] To address the aforementioned issues, this invention proposes a dynamic water-based polysaccharide extraction device for *Auricularia auricula-judae*, which effectively improves the extraction efficiency of polysaccharides through a dual-tank circulating connection design.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: a dynamic water-based auricularia auricula polysaccharide extraction device, comprising a first tank, a feed inlet at the top of the first tank, a hopper inside the first tank, the hopper including an upper baffle and a lower baffle, both the upper and lower baffles having several through holes, a water inlet at the top of the first tank, a second tank on one side of the first tank, the bottom of the first tank and the bottom of the second tank being connected by a first connecting pipe, a circulation pump on the first connecting pipe, the sidewalls of the first tank and the second tank being connected by a second connecting pipe, a stirring paddle inside the second tank, a jacket on the outer wall of the second tank, and thermometers on both the first and second tanks.

[0006] As a further embodiment of this utility model: a level gauge is provided on the side wall of the first tank to observe the liquid level in the first tank.

[0007] As a further embodiment of this utility model: the upper baffle and the lower baffle are detachably connected to the inner wall of the first tank and form a hopper with the side wall of the first tank. The side wall of the hopper is also provided with a discharge port, and the upper baffle is also provided with a movable cover plate.

[0008] As a further embodiment of this utility model: the top of the second tank is provided with a motor bracket, the motor bracket is provided with a motor, the top of the stirring paddle extends out of the second tank and is connected to the output end of the motor, and the bottom of the stirring paddle is polygonal.

[0009] As a further embodiment of this utility model: both the bottom ends of the first tank and the second tank are provided with openings, and the first connecting pipe is connected to the openings of the first tank and the second tank respectively through the first valve and the second valve.

[0010] As a further improvement of this utility model, a third valve is provided at both ends of the first connecting pipe.

[0011] As a further improvement of this utility model, the height of the second connecting pipe is higher than that of the upper baffle.

[0012] As a further improvement of this utility model: the jacket is a Miller jacket, and the jacket is provided with a medium inlet and a medium outlet.

[0013] As a further improvement of this utility model, the second tank body is also provided with a manhole.

[0014] As a further improvement of this utility model, a fourth control valve is provided on the water inlet.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The design of this utility model, through the double-tank circulation connection, forms a channel for dynamic liquid circulation between the tanks. With the setting of the hopper and circulation pump, the golden ear fungus material is continuously tumbled under the action of liquid from bottom to top, which expands the contact area between the golden ear fungus material and water, avoids the damage to the golden ear fungus material caused by traditional stirring, and forms a gentler dynamic extraction. This not only improves the extraction efficiency of golden ear fungus polysaccharides, but also allows the golden ear fungus residue and extract to be effectively separated, thereby improving the extraction quality of golden ear fungus polysaccharides. 2. This utility model uses a Miller jacket to heat the liquid in the second tank, which not only ensures the stability of the extracted liquid temperature, but also avoids component degradation caused by local overheating, thus ensuring product quality.

[0022] Both the first tank 1 and the second tank 8 have openings 20 at their bottom ends. The first connecting pipe 9 is connected to the openings 20 of the first tank 1 and the second tank 8 respectively through the first valve 21 and the second valve 22.

[0023] The first connecting pipe 9 is equipped with a third valve 23 at both ends.

[0024] The height of the second connecting pipe 11 is higher than that of the upper baffle 4.

[0025] The jacket 13 is a Miller jacket, and the jacket 13 is provided with a medium inlet 24 and a medium outlet 25.

[0026] The second tank body 8 is also equipped with a manhole 26.

[0028] Working principle: This utility model connects the first tank 1 and the second tank 8 through the first connecting pipe 9 and the second connecting pipe 11, and places the golden ear fungus material in the hopper 3. The golden ear fungus is constantly turned over by the action of circulating water from bottom to top, which expands the contact area between the golden ear fungus material and water, avoids the sedimentation of the golden ear fungus material and the damage caused by traditional stirring to the golden ear fungus, so that the golden ear fungus polysaccharide can be gently dissolved in water under high temperature dynamic conditions.

[0029] Work steps: S1. Cut the cleaned golden ear fungus into 2cm pieces, open the feed inlet 2 of the first tank 1, and open the movable cover 17 of the baffle 4 on the hopper 3.

The liquid in the second tank 8 is heated through the jacket 13. Hot steam enters from the medium inlet 24 of the jacket 13. When the liquid temperature in the second tank 8 reaches 90°C, the circulation pump 10, the first control valve 21, and the second control valve 22 are turned on. The heated liquid in the second tank 8 enters the first tank 1 through the first connecting pipe 9, and the liquid in the first tank 1 enters the second tank 8 through the second connecting pipe 11. This cycle continues, and the liquid in the second tank 8 is stirred at the same time to start the extraction of Auricularia auricula polysaccharide. During the extraction, the liquid temperature is controlled by steam at about 70°C, and the extraction time is about 8 hours. S4.
