Description

Technical Field

[0001] This utility model relates to the field of polysaccharide extraction equipment technology, and in particular to an integrated extraction device for strawberry polysaccharides used as a tobacco humectant. Background Technology

[0002] Strawberry polysaccharides are natural water-soluble polymers extracted from strawberry fruits. They possess excellent water retention, film-forming properties, and bioactivities such as antioxidant and immune-enhancing effects. In recent years, they have shown broad application prospects in the fields of food, medicine, and cosmetics.

[0003] It is worth noting that the excellent properties of strawberry polysaccharides have also attracted widespread attention in the tobacco industry. In cigarette production, moisture retention is a key indicator for evaluating tobacco quality and influencing consumer experience. Traditional tobacco humectants, such as propylene glycol and glycerin, while effective, may pose health risks with long-term use and could alter the natural aroma of tobacco. Natural plant polysaccharides, due to their safety, non-toxicity, biodegradability, and combined moisture retention and quality enhancement properties, are considered an ideal alternative or supplement to tobacco humectants. Applying strawberry polysaccharides to tobacco formulations can effectively slow down moisture loss from tobacco, maintain its resilience and combustibility, and improve smoking comfort to some extent, aligning with the current tobacco industry's development trends of "harm reduction and tar reduction" and "natural health."

[0004] Currently, strawberry polysaccharide extraction requires three major processes: raw material cell disruption, solid-liquid separation, and alcohol precipitation purification. However, existing technologies lack a dedicated integrated device for these three processes, with each step relying on separate equipment, which has significant drawbacks: In terms of equipment configuration, cell disruption, separation, and alcohol precipitation require 3-4 types of independent equipment, increasing the floor space required; in terms of operation, materials need to be manually transferred 3-4 times, extending the extraction cycle, increasing labor costs, and manual handling can easily lead to extraction interruptions; more importantly, frequent manual transfers and multi-equipment operation increase the risk of material contamination, and incomplete equipment cleaning can also cause cross-contamination, affecting polysaccharide purity; in addition, it is difficult to standardize the operation of discrete equipment, and parameter differences can easily lead to fluctuations in polysaccharide extraction rate and purity, failing to meet the quality stability requirements of tobacco improvement. Therefore, given the tobacco industry's demand for natural functional ingredients and the limitations of existing extraction technologies, there is an urgent need to develop an integrated and automated extraction device to achieve efficient and stable extraction of strawberry polysaccharides and promote their high-value application in tobacco products.

[0022] See Figure 1 and 2 This embodiment provides an integrated extraction device for strawberry polysaccharides used as a tobacco humectant, including a high-speed blender 13, a filter container, and an alcohol precipitation tank 8. Both the high-speed blender 13 and the alcohol precipitation tank 8 are positioned above the filter container. The upper part of the filter container is a rectangular storage cavity 1, and the lower part is a conical funnel cavity 2. The storage cavity 1 and the funnel cavity 2 are interconnected, forming a material flow channel. The output ends of both the high-speed blender 13 and the alcohol precipitation tank 8 are connected to the storage cavity 1.

[0023] A filter assembly 4 is installed at the connection between the storage chamber 1 and the funnel chamber 2. The filter assembly 4 includes a filter membrane and double-layer filter membrane support plates located above and below the filter membrane. Specifically, the filter membrane support plates include perforated support mesh or support grids made of plastic or metal. The pore size of the perforated structure is larger than the pore size of the filter membrane to avoid obstructing the flow of filtrate. The filter membrane is sandwiched between the two layers of support mesh or support grids, i.e., the "upper support plate + filter membrane + lower support plate" are tightly pressed and fixed together by bolts or clips to form a "detachable filter assembly 4," which is then installed as a whole at the connection between the storage chamber 1 and the funnel chamber 2. The filter assembly 4 ensures that the filter membrane remains flat and undamaged when subjected to the weight of the material. The filter assembly 4 is detachable, allowing for the replacement of filter membranes with different pore sizes to adapt to various strawberry polysaccharide extractions. In use, the filtrate separated by the filter membrane flows into the filtrate collection box along the funnel chamber 2.

[0024] The bottom end of the funnel chamber 2 is connected to the input end of the alcohol precipitation tank 8 through a pipeline equipped with a pump. Switch valves 3 are respectively installed at the bottom (outlet) of the wall-breaking machine 13, the funnel chamber 2 and the alcohol precipitation tank 8.

[0025] Pushing assemblies are respectively provided on the left and right sides of the storage cavity 1, namely the first pushing assembly and the second pushing assembly. Each pushing assembly includes a push rod and a push plate connected to the inner end of the push rod. One end of the push rod is fixedly connected to the push plate located inside the storage cavity 1, and the other end of the push rod extends to the outside of the storage cavity 1 through a connection port on the storage cavity 1. Specifically, the connection port is sealed to the push rod by a rubber sealing ring. The rubber sealing ring at the connection port is made of low-friction food-grade silicone material, which ensures a seal without hindering the sliding of the push rod. A flexible silicone sealing strip is embedded on the outer periphery of the push plate. The sealing strip fits tightly against the inner wall of the storage cavity 1 to prevent material from remaining in the gaps. Among them, the push rod of the first pushing assembly is the first push rod 9, the push plate of the first pushing assembly is the first push plate 10, the push rod of the second pushing assembly is the second push rod 11, and the push plate of the second pushing assembly is the second push plate 12.

[0026] The right side of the storage cavity 1 extends outward to form a sediment output section. A sediment collection port 5 is provided on the bottom surface of the sediment output section. A sealing door 6 is provided at the sediment collection port 5 to seal it. The upper surface of the sealing door 6 is flush with the inner bottom surface of the storage cavity 1, allowing the second push plate 12 to move smoothly to the left and right sides of the sediment collection port 5. The sealing door 6 can be either a flip-open type or a pull-out type, and can be opened manually or automatically as needed. A flexible silicone sealing strip is embedded along the edge of the sealing door 6, ensuring a sealed connection between the sealing door 6 and the sediment collection port 5. A downwardly sloping sediment slide 7 is also connected to the left edge of the sediment collection port 5, and a sediment collection box is located below the sediment slide 7.

[0027] See Figure 1When filtration is required, the second pusher plate 12 of the second pusher assembly moves to the left side of the sediment collection port 5 (between the sediment collection port 5 and the filter assembly); see reference Figure 2 When it is necessary to collect sediment, the second push plate 12 of the second push assembly moves to the right side of the sediment collection port 5, opens the sealing door 6, and pushes the first push assembly to the right to push the sediment out of the sediment collection port 5. The sediment slides along the sediment slide 7 into the sediment collection box.

[0028] As an implementation of this embodiment, a transparent observation window is provided on the storage cavity 1 to facilitate observation of the position of the first / second pushing components.

[0029] As an embodiment of this invention, an ultrasonic device is embedded in the inner wall of the blender 13 to assist in extraction.

[0030] In this embodiment, the pushing component is connected to a driving member, which is an electric push rod, a pneumatic cylinder or a hydraulic cylinder, etc. The driving member can drive the first / second pushing component to move back and forth along the horizontal direction of the storage cavity 1.

[0031] The specific usage steps of this embodiment are as follows: The second pusher plate 12 of the second pusher assembly moves to the left side of the sediment collection port 5 (e.g., Figure 1 (As shown), strawberries are placed in a blender 13 and crushed, with extraction assisted by an ultrasonic device. After crushing, the mixture flows into a filter container, passes through the filter assembly 4, and the first and second pushing components are moved inward simultaneously or only the first pushing component is pushed to squeeze the material to be filtered, achieving solid-liquid separation. The polysaccharide filtrate flows into the funnel cavity 2. The second pusher plate 12 of the second pushing component moves to the right side of the sediment collection port 5 (as shown). Figure 2 As shown), open the sealing door 6, push the first pushing component to the right to push the fruit pulp sediment out of the sediment collection port 5, and slide it into the sediment collection box along the sediment slide 7.

[0032] The first and second pushing components return to their initial positions (the first push plate 10 is located at the far left of the storage cavity 1, and the second push plate 12 is located as follows). Figure 1 (Left side of precipitate collection port 5) Open the switch valve 3 at the bottom of funnel chamber 2, and pump it into alcohol precipitation tank 8. Add the appropriate amount of alcohol into alcohol precipitation tank 8 for alcohol precipitation, let it stand, and generate precipitate. Open the switch valve 3 at the bottom of alcohol precipitation tank 8, and the material in alcohol precipitation tank 8 flows into the storage chamber 1 of the filter container for solid-liquid separation again. The separated polysaccharide precipitate is discharged and collected from precipitate collection port 5, and the filtrate (alcohol) flows into funnel chamber 2 for collection.

[0033] Although the specific embodiments of the utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the utility model. Based on the technical solution of the utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the utility model.
