Description

Steaming and drying device for processing rhizoma polygonati

Technical Field

The invention relates to the technical field of traditional Chinese medicine processing, in particular to a steaming and drying device for processing rhizoma polygonati.

Background

The 'nine steaming and nine sunning' refers to an ancient method for processing traditional Chinese medicines by adopting repeated steaming and sunning processing processes, the specific details are different according to different varieties of the medicinal materials and mainly aim to rectify the medicine properties or increase effective components and reduce toxic components, wherein the steaming generally refers to steaming the medicinal materials by using water vapor to reduce the toxic components, then taking out the medicinal materials, spreading and sunning the medicinal materials for enough to remove water in the medicinal materials, and the 'nine' refers to the meaning of more than one and is not necessarily nine times; the crude rhizoma polygonati has high mucus content and obvious stimulation to throat, so the rhizoma polygonati needs to be processed by the method, the usage of the rhizoma polygonati in the compendium of materia medica records that the rhizoma polygonati is eaten after nine times of steaming, the effects of retaining youthfulness and breaking the valley, tonifying deficiency, stopping cold and heat, filling essence and marrow and killing three corpses, and the rhizoma polygonati is steamed to nine times and has the standard of black color, sweet taste and moistening.

According to the documentation of the polysaccharide and saponin content change in the processing process of polygonatum kingianum published in 12 years 2015 of the journal of China, namely the polysaccharide and saponin content change in the processing process of the polygonatum kingianum, the rhizome of polygonatum kingianum is gradually reduced in the repeated steaming and drying process, the saponin content is gradually increased, and in addition, the alcohol extract, the water extract, the reducing sugar and the free amino acid in the polygonatum kingianum are also increased in brightness, so that the polygonatum kingianum can be reduced in toxicity and increased in efficiency after being steamed and dried for nine times, the important part containing more mucilage is more easily affected with damp and mildewed in the storage process, and the polygonatum kingianum after being steamed for nine times is more beneficial to storage.

However, the existing sealwort processing equipment cannot realize the rapid generation of water vapor in time, the generated amount of water vapor during steaming can be met only after the temperature in the equipment reaches a certain degree, and especially for a repeated preparation process of nine times of steaming and nine times of drying, a large amount of time is spent for waiting for the generation of water vapor so as to reach the processing conditions.
