Embodiment 1

[0023] A preparation method of fresh notoginseng freeze-dried broken wall superfine powder,

[0024] (1) Soak fresh Panax notoginseng in water, and perform wet crushing after soaking;

[0025] (2) vacuum freeze-drying the notoginseng wet powder after wet crushing;

[0026] (3) The notoginseng powder after vacuum freeze-drying is subjected to wall-breaking treatment.

[0027] The crushing speed is 900r / min, and the crushing time is 20min; in the vacuum freeze-drying step, the thickness of the material is 0.5mm, the freeze-drying temperature is -10°C, and the freeze-drying vacuum is 5Pa; after freeze-drying, the temperature is raised rapidly; In the treatment step, the wall-breaking temperature is 15°C, and the wall-breaking time is 20 minutes; an ultrasonic treatment step is also included before the wall-breaking treatment step; the ultrasonic treatment time is 40 minutes;

Embodiment 2

[0029] A preparation method of fresh notoginseng freeze-dried broken wall superfine powder,

[0030] (1) Soak fresh Panax notoginseng in water, and perform wet crushing after soaking;

[0031] (2) vacuum freeze-drying the notoginseng wet powder after wet crushing;

[0032] (3) The notoginseng powder after vacuum freeze-drying is subjected to wall-breaking treatment.

[0033] The crushing speed is 700r / min, and the crushing time is 15min; in the vacuum freeze-drying step, the material thickness is 0.8mm, the freeze-drying temperature is -15°C, and the freeze-drying vacuum degree is 10Pa; in the wall-breaking treatment step, the wall-breaking temperature is 10°C, the wall-breaking time is 40 minutes; before the wall-breaking treatment step, an ultrasonic treatment step is also included; the ultrasonic treatment time is 70 minutes;

Embodiment 3

[0035] The process steps and parameters of the preparation method of Example 1 are basically the same, the difference is that the fresh Panax notoginseng is not soaked in water.

Abstract

The application of the invention discloses a preparation method of fresh pseudo-ginseng freeze-dried wall-breaking submicron powder. The preparation method comprises the following steps of (1) soakingfresh pseudo-ginseng in water, and after the fresh pseudo-ginseng is soaked, performing wet type crushing; (2) performing vacuum freeze drying on pseudo-ginseng wet powder after being subjected to wet type crushing; and (3) performing wall-breaking treatment on the pseudo-ginseng powder after being subjected to vacuum freeze drying. Through the adoption of the preparation method disclosed by theinvention, the shortcomings of a conventional scattering technology that loss is high, clumping is easy to generate and the fineness is instable are overcome. Through the preparation method of the freeze-dried wall-breaking submicron powder, pseudo-ginseng cell tissues are obviously changed, through cell wall-breaking, effective components of pseudo-ginseng are better exposed out, and the biological utilization value of the pseudo-ginseng is greatly increased.

Description

technical field [0001] The application relates to the deep processing of medicinal materials, in particular to a preparation method of fresh notoginseng freeze-dried broken-wall superfine powder. Background technique [0002] The ingredients of Panax notoginseng powder are the same as the main root of Panax notoginseng. It is rich in active ingredients of notoginseng saponins, notoginseng polysaccharides, notoginseng, and flavonoids. Oxygen, anti-aging, lowering blood fat, lowering blood pressure, improving the immune function of the body and so on. [0003] At present, the processing of Panax notoginseng powder often adopts small-scale grinding machines for powdering. This processing method is simple and easy, but there are some shortcomings. First of all, the loss is relatively large. Due to the high price of Panax notoginseng, severe loss directly makes the powdering cost higher; secondly, fresh Panax notoginseng has a lot of water, and it is easy to agglomerate and aggl...
