Pseudo-ginseng freeze-drying processing system and control method thereof

Abstract

The invention discloses a pseudo-ginseng freeze-drying processing system. The pseudo-ginseng freeze-drying processing system comprises a vacuum freeze drier, a near infrared spectrum detector and a controller, the near infrared spectrum detector is used for acquiring the near infrared spectrum of to-be-processed pseudo-ginseng in the vacuum freeze drier; a control instruction is stored in the controller to control the vacuum freeze drier to work; and the controller further internally stores a moisture quantitative analysis model for different freeze-drying stages of a standard pseudo-ginseng sample, the controller measures the moisture of the near infrared spectrum of the to-be-detected pseudo-ginseng according to the moisture quantitative analysis model for different freeze-drying stages,the controller judges whether the moisture of the to-be-detected pseudo-ginseng reaches the moisture content of the standard pseudo-ginseng sample at the current freeze-drying stage, and if so, thenthe vacuum freeze drier is controlled to regulate the freeze-drying control data or stop working. A near-infrared spectroscopy is used to detect the moisture content of the pseudo-ginseng in the freeze-drying processing process, the freeze-drying control data are automatically regulated according to the detection result, the energy is saved, and the quality of the freeze-dried pseudo-ginseng is also guaranteed.

Description

technical field [0001] The invention relates to the technical field of processing ginseng medicinal materials, in particular to a notoginseng freeze-drying processing system and a control method thereof. Background technique [0002] Notoginseng (Panax notoginseng) is a plant of the genus Araliaceae. It is a famous and precious Chinese medicinal material both at home and abroad. It is also one of the earliest medicinal and edible plants used by Chinese folks. King" and other reputations. Panax notoginseng first originated from the residual plants in the ancient tropical mountainous areas of the Tertiary Period 25 million years ago. Wenshan Prefecture has become the origin and main origin of Panax notoginseng because of its unique soil and climate. The history of Panax notoginseng planting has been from wild domestication to artificial planting for more than 600 years. The area and output of Panax notoginseng have remained at about 100,000 mu and 9 million kilograms all yea...

AI Technical Summary

Problems solved by technology

[0004] At present, most medicinal materials are dried by vacuum freeze-drying technology. The current freeze-drying process of traditional Chinese medicine lacks real-time monitoring of the moisture content of the material, and the freeze-drying control of the vacuum freeze-drying machine cannot be automatically adjusted according to the moisture content of Sanqi during the freeze-drying process. data
