Description

Technical Field

[0001] The utility model relates to the technical field of medicinal material processing, in particular to a steaming and baking device used for pre-processing polygonatum. Background Art

[0002] Polygonatum sibiricum is a perennial herbaceous plant of the Asparagaceae family. Its stem is root-shaped and contains rich nutrients and effective ingredients. The content of polysaccharides, oligofructose and fructose in the rhizome of Polygonatum sibiricum accounts for about 50%. It has the effects of replenishing qi and nourishing yin, strengthening the spleen, moistening the lungs and benefiting the kidneys. It can be used to treat spleen and stomach qi deficiency, fatigue, lung deficiency and dry cough, internal heat and thirst, etc.

[0003] Because of its thick rhizome, it is difficult to dry it thoroughly by traditional sun-drying method, which will cause it to rot and is not conducive to storage. In addition, raw polygonatum has a numbing taste and stings the throat, so it is often processed by steaming, among which the "nine steaming and nine drying" method is the most common.

[0004] Traditionally, the equipment for the nine-steaming and nine-drying process of Polygonatum sibiricum is mostly a wooden steamer heated by water. This method is low in cost but inefficient. In addition, the steamed Polygonatum sibiricum needs to be dried in the sun. This takes a long time and cannot be steamed and dried in one. In modern times, wooden steamers are transformed into stainless steel or aluminum steamers, which increase their service life, but are still inefficient.

[0005] The existing application number is CN202211231107.8, and the patent name is a steaming device and steaming process for Chinese herbal medicine pieces of polygonatum, which includes: a steaming box and a plurality of steaming trays embedded in the upper end of the steaming box, a steam guide assembly is provided through the rear end of the inner side of the steaming box, and a dirt suction mechanism is installed through the inner side of the working box. However, the steaming of polygonatum in the device is not uniform, which affects the steaming effect and efficiency of polygonatum, and the polygonatum needs to be carried and dried by workers, which has high labor intensity and low processing efficiency.

[0006] Specifically, the device sets the heat source at the bottom of the steaming tray, so the bottom steamer is often heated more than the upper steamer. The temperature difference in the vertical direction causes uneven heating of the steamers at different positions, which may easily result in incomplete steaming of some polygonatum, resulting in poor steaming effect of some polygonatum. Although the steaming time can be extended to a certain extent, the steaming efficiency is affected. Secondly, when the number of polygonatum placed on the steamer is too dense, it will further cause uneven heating of the upper steamer.

[0007] Therefore, how to combine steaming and drying, and to provide a device to ensure that the Polygonatum odoratum is evenly heated when steaming it, is a technical problem that urgently needs to be solved. Utility Model Content

[0065] Specifically, during the steaming process, water vapor moves along the V-shaped guide plate 74, enters the steam guide groove 721 of the steam distribution block 7, and then enters the air inlet 811 through the steam distribution hole 722 connected to the steam guide groove 721, and then enters the transverse through hole 831 of the steaming rack 83. Part of the steam is discharged from the air outlet 833 directly connected to the transverse through hole 831, and part of the steam enters the longitudinal through hole 832, and then is discharged from the air outlet 833 directly connected to the longitudinal through hole 832. In the process of moving, the steam can heat the steaming rack 83, thereby further improving the uniformity of steaming the Polygonatum sibiricum, improving the steaming effect of the Polygonatum sibiricum, and improving the steaming efficiency.

[0066] Specifically, during the vacuum process, the micro vacuum pump 12 starts working, water vapor enters from the vacuum inlet hole 822, then enters the second vacuum hole 732 through the connecting hole 821, and finally enters the air inlet of the micro vacuum pump 12 through the first vacuum hole 731, and is finally discharged from the air outlet of the micro vacuum pump 12.
