DETAILED DESCRIPTION

[0014] In order to more clearly illustrate the technical solutions of the embodiments of the utility model, the drawings required for use in the embodiments are briefly introduced below. Obviously, the drawings described below are some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0015] Please see Figures 1 to 3A wolfberry powdering device 10 includes a wolfberry dried fruit storage bin 20, a vacuum pump 30, a liquid nitrogen tank 40, a powdering mechanism 50, and a wolfberry powder storage tank 60. The air outlet of the wolfberry dried fruit storage bin 20 is connected to the vacuum pump 30 through a pipeline to exhaust the air in the wolfberry dried fruit storage bin 20. The air inlet of the wolfberry dried fruit storage bin 20 is connected to the air inlet of the liquid nitrogen tank 40 through a pipeline to introduce low-temperature nitrogen. The discharge port of the wolfberry dried fruit storage bin 20 is connected to the feed port of the powdering mechanism 50 to beat the wolfberry dried fruit into wolfberry powder. The discharge port of the powdering mechanism 50 is connected to the wolfberry powder storage tank 60 to collect the wolfberry powder in time.

[0016] The wolfberry dried fruit storage bin 20 of the utility model can store a large amount of wolfberries at one time, and can be used for the powdering mechanism 50 to powder more than one time, thereby reducing the chance of the powdering mechanism 50 contacting with air due to adding wolfberry dried fruits.

[0017] The vacuum pump 30 of the utility model is used to extract air from the wolfberry dried fruit storage bin 20 and even from the subsequent tank bodies connected to the wolfberry dried fruit storage bin 20, so as to reduce the contact between wolfberry powder and oxygen during the powdering process.

[0018] The liquid nitrogen tank 40 of the utility model is used to provide low-temperature nitrogen for the wolfberry dried fruit storage bin 20. The nitrogen can increase the micro-positive pressure environment for the wolfberry dried fruit storage bin 20, reduce the amount of external air entering, and provide a low-oxygen and low-temperature environment, which is more conducive to the powdering of the wolfberry dried fruit.

[0019] The wolfberry powder storage tank 60 of the utility model is used to hold the wolfberry powder that has been ground into powder. In the prior art, after the wolfberry dried fruit is ground into powder, the cover of the powdering mechanism 50 needs to be opened, and then the wolfberry powder is poured into the packaging bag. In this way, the wolfberry powder will still come into contact with the air, thereby causing more wolfberry powder to oxidize. The wolfberry powder storage tank 60 of the utility model allows the wolfberry dried fruit to be directly filled into the wolfberry powder storage tank 60 after being ground into powder, avoiding contact with the air, thereby reducing the oxidation of the wolfberry powder.

[0020] The powdering mechanism 50 of the utility model is used to grind the wolfberry dried fruit into powder. The powdering mechanism 50 in the prior art generally contacts with the air after the cover is opened. The oxygen content in the powdering mechanism 50 is the same as the oxygen content in the air. During the powdering process, part of the wolfberry powder will be oxidized by the oxygen in the powdering mechanism 50. However, the powdering mechanism 50 of the utility model and the wolfberry dried fruit storage bin 20 do not contact with the outside air during the wolfberry addition process, and the oxidation degree of the wolfberry powder is lower.

[0021] There are many ways to convey the wolfberry dried fruit from the wolfberry dried fruit storage bin 20 to the powdering mechanism 50, such as conveying by a belt conveyor or conveying by a negative pressure fan 70. In a preferred embodiment, the lower end of the wolfberry dried fruit storage bin 20 is conical, and a screw conveyor 201 is provided at the bottom of the wolfberry dried fruit storage bin 20. The discharge port of the screw conveyor 201 is connected to the feed port of the powdering mechanism 50, and the top of the wolfberry dried fruit storage bin 20 is provided with a feed port. When powdering, the feed port is in a sealed state. The screw conveyor 201 can ensure the stability of the wolfberry dried fruit conveying flow rate and can realize the continuous powdering of wolfberries. At the same time, it can also maintain a good sealing environment for the wolfberry dried fruit storage bin 20 to reduce the oxidation of wolfberry dried fruit.

[0022] In a preferred embodiment, the powdering mechanism 50 includes a powdering tank 501, a cutter head 502, and a drive motor 503. The cutter head 502 is provided at the bottom of the powdering tank 501. The rotating shaft of the cutter head 502 is fixedly connected to the rotating shaft of the drive motor 503 so as to drive the cutter head 502 to rotate through the drive motor 503. The side wall of the powdering tank 501 is provided with a feed port, and the feed port of the powdering tank 501 is connected to the wolfberry dried fruit storage bin 20. The structure of the powdering mechanism 50 of the present utility model is similar to that of the powdering mechanism 50 in the prior art. The side wall of the powdering mechanism 50 of the present utility model is provided with a feed port, and the wolfberry dried fruit enters from the side of the powdering tank 501.

[0023] In a preferred embodiment, a negative pressure fan 70 is provided between the powder beating mechanism 50 and the wolfberry powder storage tank 60, the air inlet of the negative pressure fan 70 is connected to the discharge port of the powder beating mechanism 50 through a pipeline, the air outlet of the negative pressure fan 70 is connected to the feed port of the wolfberry powder storage tank 60 through a pipeline, and a filter net 504 is also provided at the discharge port of the powder beating mechanism 50 to filter large particles of wolfberry powder.

[0024] In this way, the continuity of the wolfberry powdering process can be ensured. Specifically, wolfberry dry fruits continuously enter the powdering mechanism 50 from the side wall of the powdering mechanism 50, and under the action of gravity, the wolfberry dry fruits fall to the bottom of the powdering tank 501, and are ground into powder by the cutter head 502. The gravity of the wolfberry after being ground into powder becomes smaller, and under the action of the negative pressure fan 70, it enters the wolfberry powder storage tank 60 from the top of the powdering tank 501. At the same time, the larger wolfberry particles attracted by the negative pressure fan 70 fall back to the bottom of the powdering tank 501 under the action of the filter 504. In order to make this part of the wolfberry have a better falling effect, the negative pressure fan 70 can be operated intermittently.

[0025] The wolfberry powder entering the wolfberry powder storage tank 60 still has a certain amount of kinetic energy under the action of the negative pressure fan 70, which affects the falling of the wolfberry powder. During the exhaust process, the wolfberry powder is easily taken out from the exhaust port. Therefore, in a preferred embodiment, the wolfberry powder storage tank 60 is also provided with an exhaust filtering mechanism 601 to separate the wolfberry powder. The exhaust filtering mechanism 601 includes a partition 6011, a mesh bracket 6012, and a filter bag 6013. The partition 6011 divides the wolfberry powder storage tank 60 into two upper and lower chambers, wherein the chamber above the partition 6011 is an exhaust chamber, and the chamber below the partition 6011 is a wolfberry powder sedimentation chamber. The partition 6011 is provided with a plurality of holes, and the mesh bracket 6012 is arranged on the holes of the partition 6011. The mesh bracket 6012 is columnar and is located in the wolfberry powder sedimentation chamber. The filter bag 6013 is mounted on the mesh bracket 6012. The side wall of the wolfberry powder sedimentation chamber is provided with a wolfberry feed port, and the side wall of the exhaust chamber is provided with an air outlet.

[0026] In this way, the wolfberry powder loses kinetic energy under the action of the filter bag 6013 and falls to the bottom of the wolfberry powder storage tank 60. The wind passes through the filter bag 6013 and is discharged from the air outlet.

[0027] The above disclosure is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of the present invention. A person skilled in the art can understand that all or part of the processes of the above embodiments and equivalent changes made according to the claims of the present invention still fall within the scope of the present invention.
