Description

Technical Field

[0001] The utility model relates to extraction equipment, in particular to a polysaccharide extractor. Background Art

[0002] Ultrasonic extraction of polysaccharides is one of the commonly used methods for polysaccharide extraction at present. Its principle is that when ultrasonic waves propagate in a liquid, they can produce a violent effect, causing the cell walls, cell membranes, etc. to rupture, releasing polysaccharide molecules, and then obtaining polysaccharide extraction products through subsequent centrifugal separation. However, although ultrasonic extraction of polysaccharides has advantages such as high efficiency, short time, and small loss of nutrients, the high energy of ultrasonic waves may also damage the partial molecular structure of polysaccharides, thus affecting the extraction rate of polysaccharides. Currently, most of the ultrasonic extractors used for polysaccharide extraction have a general structure and lack a cooling protection structure. Therefore, there is an urgent need to provide a new type of polysaccharide extractor with a simple and feasible structure and a cooling protection function. Summary of the Utility Model

On the temperature measuring pipeline communicated with the cooling cavity by the temperature measuring interface valve, a second probe-type thermometer is arranged, and the probe of the second probe-type thermometer penetrates into this temperature measuring pipeline.

[0007] Preferably, a liquid inlet channel communicating with the inner cavity of the extraction tank is arranged at the top of the extraction tank, and a liquid outlet channel communicating with the inner cavity of the extraction tank is arranged at the bottom of the extraction tank 1.

[0018] The following further describes the utility model in detail with reference to the drawings and specific embodiments.

[0019] The utility model discloses a polysaccharide extractor, and the overall structure setting is as Figure 1As shown in the figure, it includes an extraction tank 1. The extraction tank 1 serves as the main place for ultrasonic extraction of polysaccharides. First, a liquid inlet channel 3 communicating with the inner cavity of the extraction tank 1 is provided at the top of the extraction tank 1, and a liquid outlet channel 18 communicating with the inner cavity of the extraction tank 1 is provided at the bottom of the extraction tank 1. The liquid inlet channel 3 is externally connected to a liquid delivery pump through a pipeline for feeding the solution to be ultrasonically treated; the liquid outlet pipe 18 is used for sending out the completed solution, so as to facilitate subsequent centrifugal separation treatment.

[0020] Secondly, an ultrasonic probe 20 is inserted into the extraction tank 1. The structure of the ultrasonic probe 20 is set as Figure 2 shown. It extends into the extraction tank 1 and contacts the solution. By connecting to the ultrasonic generator through the connector 6, ultrasonic energy is transmitted to the solution, so that the cell walls, cell membranes, etc. of the solute in the solution to be ultrasonically treated fed into the extraction tank 1 are ruptured, and polysaccharide molecules are released.

[0021] For the ultrasonic probe 20, it is specifically set through an interface type installation platform 8 and an installation flange 7. The ultrasonic probe 20 is fixed on the installation flange 7. Correspondingly, an interface type installation platform 8 for supporting the ultrasonic probe 20 is provided at the top of the extraction tank 1. The installation flange 7 and the interface type installation platform 8 are adaptively connected through a bolt assembly, so as to realize the installation and setting of the ultrasonic probe 20.

[0022] Preferably, a sealing ring is clamped between the installation flange 7 and the interface type installation platform 8.

[0023] Preferably, a top plate 5 is fixed at the top of the connector 6, and a cooling fan 4 is installed at the top plate 5 to dissipate heat from the heat - prone connector.

[0024] Considering that the high - temperature energy of the existing ultrasonic polysaccharide extraction tank may damage the partial molecular structure of polysaccharides, thus affecting the extraction rate of polysaccharides, the polysaccharide extractor disclosed in this new model is provided with an outer cover tank 2 outside the extraction tank 1. To make the setting of the outer cover tank 2 simple and feasible, it is also as Figure 1 shown. Based on the structure of the extraction tank 1, an upper fixing plate 10 and a lower fixing plate 17 are welded and fixed at intervals on the outer side of the tank wall of the extraction tank 1. The outer cover tank 2 is set based on the upper fixing plate 10 and the lower fixing plate 17. The outer cover tank 2 includes two semi - cylindrical cover bodies. The two cover bodies are assembled between the upper and lower fixing plates, and the two cover bodies are welded into one body at the symmetrically distributed welds, and then the connection between the upper fixing plate 10 and the cover body and the connection between the lower fixing plate 17 and the cover body are welded into one body, so as to realize the setting of the outer cover tank 2 outside the extraction tank 1 and the covering outside the extraction tank 1, so as to form a cooling cavity together with the extraction tank.

[0025] The cooling jacket can be used for the passage of coolant. A first probe thermometer 9 is provided at the top of the extraction tank 1. The probe of the first probe thermometer 9 extends into the extraction tank 1 and can contact the solution in the extraction tank 1 to achieve temperature monitoring. When the monitored solution temperature is higher than the preset value, the coolant circulation pump is started to pump the coolant into the cooling jacket. Correspondingly, a liquid level sensor is provided in the cooling jacket. When the added coolant reaches the monitored liquid level of the liquid level sensor, the coolant circulation pump will stop adding coolant.

[0026] Therefore, correspondingly, a coolant inlet 11 and a coolant outlet 19, which are respectively connected to the cooling jacket, are provided on the tank wall of the outer cover tank 2. The coolant inlet 11 is at the highest position of the cooling jacket, and the coolant outlet 19 is at the lowest position of the cooling jacket, so that the coolant in the cooling jacket can be discharged smoothly.

[0027] To avoid the situation where the temperature of the coolant rises to an unusable level and is not replaced in time after heat exchange, a temperature measurement interface valve 15 is also provided on the tank wall of the outer cover tank 2. The temperature measurement interface valve 15 is normally closed. A second probe thermometer 9 is provided on the temperature measurement pipeline connecting the temperature measurement interface valve 15 and the cooling jacket. The probe of the second probe thermometer 9 penetrates into the temperature measurement pipeline to monitor the temperature of the coolant. A valve is provided at the coolant outlet 19. When the second probe thermometer 9 monitors that the temperature of the coolant is higher than the preset usable temperature, the coolant outlet 19 will be opened to discharge the coolant. If the solution temperature in the extraction tank 1 is still higher than the preset value of the first probe thermometer 9 at this time, the pumping of the coolant will continue. If the solution temperature in the extraction tank 1 is lower than or equal to the preset value of the first probe thermometer 9, the coolant circulation pump will not start, and the cooling jacket will be in a state without coolant.

[0028] It can be seen from this that in this new type, when ultrasonic waves propagate in a liquid, intense physical effects will be generated, such as breaking cell walls and cell membranes, etc., thereby promoting the release and extraction of polysaccharides. And, ultrasonic waves can also cause the movement and vibration of molecules in the liquid, strengthening the dissolution and diffusion of polysaccharides. At the same time, considering the situation that the high-temperature energy of ultrasonic waves may damage the partial molecular structure of polysaccharides, thereby affecting the extraction rate of polysaccharides, a cooling structure is designed outside the extraction tank to achieve temperature reduction protection to ensure the extraction rate of polysaccharides.

Changes, modifications, additions or substitutions made by those skilled in the art within the technical scope of the present invention also fall within the protection scope of the present invention.
