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.
