Description

Technical Field

[0001] The utility model relates to the technical field of polygonatum processing, in particular to a polygonatum low-temperature drying machine. Background Art

[0002] Polygonatum sibiricum grows in mountain forest edges, shrubs or semi-shaded hillsides. Polygonatum sibiricum is a perennial herb. Polygonatum sibiricum is a traditional Chinese medicinal material that is not common in daily life. It is also called chicken-headed Polygonatum sibiricum, yellow chicken vegetable, pen tube vegetable, claw ginseng, tiger ginger and chicken claw ginseng. The rhizome is horizontal, cylindrical, with enlarged nodules, whorled leaves, and sessile. It is a medicinal plant that has the effects of tonifying the spleen, moistening the lungs and promoting fluid production. In the production process of Polygonatum sibiricum, it needs to be dried to make the medicinal effect purer, remove unnecessary flavors, and make it safer to take. Currently, it is suitable for low-temperature drying of Polygonatum sibiricum on the market, but there are still some disadvantages;

[0003] The existing low-temperature drying machine for polygonatum directly puts polygonatum into the drying machine for drying. Polygonatum powder may clump when entering the drying machine, which will cause uneven drying of polygonatum. At the same time, polygonatum cannot fall evenly in the drying machine. Accumulation together will only make the polygonatum on the outside dry, which will also cause problems such as uneven drying. For example, a Chinese utility model patent with authorization announcement number CN210292666U discloses a polygonatum drying machine, including a box body, a heating device, and a drying trough body. The heating device is fixedly arranged at the bottom of the box body, the drying trough body is arranged in the box body and is located above the heating device, and the drying trough body is connected to a A driving device is provided for driving the horizontal movement of the drying machine in the box body, wherein the driving device comprises a frame body, a pulley assembly, a driving motor, an extrusion cam pressure-bearing protrusion and a connecting rod. The driving motor drives the first pulley to rotate, and the rotation of the first pulley drives the second pulley to rotate through a belt. The second pulley rotates and the extrusion cam on the constant moving shaft rotates. The extrusion cam rotates to intermittently extrude the pressure-bearing protrusion. The resetting component is used for resetting the pressure-bearing protrusion, so that the connecting rod on the pressure-bearing protrusion makes a horizontal reciprocating motion, thereby driving the drying tank body to make a horizontal reciprocating motion, thereby achieving a uniform drying effect, solving the problem of uneven drying in traditional drying devices and improving the quality of Huangjing processing. However, this device has the problem of directly putting the polygonatum into the dryer for drying. The polygonatum powder may clump when entering the dryer, which will cause uneven drying of the polygonatum. At the same time, the polygonatum cannot fall evenly in the dryer. Accumulation together will only make the polygonatum on the outside dry, which will also cause uneven drying. In addition, when the polygonatum is taken out after drying, there will be problems such as polygonatum residues in the dryer. Therefore, we propose a low-temperature polygonatum dryer to solve the above problems. Utility Model Content
