Lyophilized ginseng processing system and control method thereof

Abstract

The invention discloses a lyophilized ginseng processing system. The lyophilized ginseng processing system comprises a vacuum freezing dryer, a near infrared spectrum detector and a controller. The near infrared spectrum detector is used for collecting near infrared spectrums of to-be-detected ginsengs in the vacuum freezing dryer. A control instruction is stored in the controller, and the controller is used for controlling the vacuum freezing dryer to work. Moisture quantitative analysis models of standard ginseng samples at different lyophilizing stages are further stored in the controller,the controller conducts moisture measuring on the near infrared spectrums of the to-be-detected ginsengs according to the moisture quantitative analysis models at the different lyophilizing stages andjudges whether the moisture content of the to-be-detected ginsengs reaches the moisture content of the standard ginseng samples at the current lyophilizing stage or not, if the judgment result is that the moisture content of the to-be-detected ginsengs reaches the moisture content of the standard ginseng samples at the current lyophilizing stage, the vacuum freezing dryer is controlled to adjustlyophilizing control data or stop working. The moisture content of the ginsengs in the lyophilizing processing process is detected through a near infrared spectrometer, the lyophilizing control data are automatically adjusted according to the detecting result, and not only are energy sources saved, but also the quality of the lyophilized ginsengs can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of processing ginseng medicinal materials, in particular to a freeze-dried ginseng processing system and a control method thereof. Background technique [0002] Our country is extremely rich in resources of ginseng medicinal materials. It grows in a pollution-free natural environment and is a pure natural medicine and health care product. Since the harvest of ginseng medicinal materials is very seasonal, how can we ensure that the nutritional components of ginseng medicinal materials are not destroyed? Destruction is the number one concern. [0003] Nowadays, in the processing of ginseng medicinal materials, the usual method is to dry the ginseng medicinal materials at room temperature, and also soak them in alcohol, smoke them with sulfur, soak them in preservatives, soak them in mixed preservatives, and make them into cans, etc. , but the air-drying process at room temperature takes a long time, and it is...

[0003] Nowadays, in the processing of ginseng medicinal materials, the usual method is to dry the ginseng medicinal materials at room temperature, and also soak them in alcohol, smoke them with sulfur, soak them in preservatives, soak them in mixed preservatives, and make them into cans, etc. , but the air-drying process at room temperature takes a long time, and it is easy to cause some components of ginseng medicinal materials to deteriorate. The above-mentioned other processes add other substances, which will have a certain impact on the quality of ginseng medicinal materials. There is a lack of ginseng medicinal materials that can maintain the quality of ginseng medicinal materials. Processing system
