Dendrobe lyophilization processing system and control method thereof

Abstract

The invention discloses a dendrobe lyophilization processing system which comprises a vacuum freezing drier, a near infrared spectrum detector and a controller, wherein the near infrared spectrum detector is used for collecting near infrared spectra of to-be-detected dendrobe in the vacuum freezing drier; the controller stores a control command for controlling the vacuum freezing drier to work; the controller also stores water quantitative analysis models of a standard dendrobe sample in different lyophilization stages, measures water of the near infrared spectra of to-be-detected dendrobe according to the water quantitative analysis models in the different lyophilization stages and judges whether water of the to-be-detected dendrobe reaches the water content of the standard dendrobe sample in the current lyophilization stage or not; if so, the controller controls the vacuum freezing drier to adjust the lyophilization control data or controls the vacuum freezing drier to stop working.By detecting the water content of the dendrobe in the lyophilization processing course by means of the near infrared spectroscopy and adjusting the lyophilization control data automatically accordingto the detection result, energy sources are saved, and the quality of lyophilized dendrobe can be also guaranteed.

Description

technical field [0001] The invention relates to the technical field of processing ginseng medicinal materials, in particular to a dendrobium freeze-drying processing system and a control method thereof. Background technique [0002] Dendrobium is a famous and precious Chinese medicinal material, containing more than 10 kinds of alkaloids. The water-soluble polysaccharides contained in it can significantly enhance immunity, anti-aging, anti-radiation, etc., and are effective for digestive system, respiratory system, cardiovascular system and eye diseases. Obvious curative effect. The medicinal materials processed from dendrobium are expensive and are very valuable medicines and tonics. [0003] In recent years, due to the improvement of living standards, the traditional medicinal and functions of Dendrobium have been paid attention to, the production technology has also been developed, and the production scale is expanding. At present, there are dendrobium cultivation or ex...

Problems solved by technology

At present, Zhejiang leads the country in processing and marketing. The main commodity forms of Dendrobium on the market are maple bucket, powder, capsule, etc.; and these products are all made from its dried Dendrobium, and the dried Dendrobium is made from fresh strips of Dendrobium. It is obtained by natural drying or drying. The common feature of processing is that fresh dendrobium needs to be heat-treated, which greatly damages active ingredients such as alkaloids and water-soluble polysaccharides in dendrobium, resulting in loss of medicinal efficacy of dendrobium; moreover, dendrobium candidum cells The cell wall of Dendrobium officinale is mainly composed of cellulose and pectin, which greatly hinders the penetration of water-soluble polysaccharides, the functional component of Dendrobium officinale

[0004] At present, most medicinal materials are dried by vacuum freeze-drying technology, and the materials must be processed before drying, especially the cleaning of the materials. However, the cleaning device equipped with the current freeze-drying equipment is not perfect for the treatment of residual water, and all of them need to be manually processed. Processing will seriously affect the speed of freeze-drying. At the same time, manual processing is likely to cause pollution, and the current drying process of traditional Chinese medicine lacks real-time monitoring of the moisture content of the material, and it is impossible to better control the variation and quality of each intermediate. Therefore, the quality of the final product cannot be guaranteed
