Embodiment 1

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

[0024] (1) Soak fresh Dendrobium officinale in water, and wet pulverize after soaking;

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

[0026] (3) the dendrobium officinale powder after vacuum freeze-drying is carried out microwave heat treatment, after heating, quench;

[0027] (4) The cooled dendrobium officinale powder is subjected to wall-breaking treatment.

[0028] The crushing speed is 800r / min, and the crushing time is 20min; in the vacuum freeze-drying step, the material thickness is 0.8mm, the freeze-drying temperature is -20°C, and the vacuum degree of freeze-drying is 10Pa; after freeze-drying, the temperature is raised rapidly; microwave heating The time is 30min; in the wall-breaking treatment step, the wall-breaking temperature is 25°C, and the wall-breaking time is 50min; an ultrasonic treatment step is also inclu...

Embodiment 2

[0030] A preparation method of fresh Dendrobium officinale freeze-dried broken wall superfine powder,

[0031] (1) Soak fresh Dendrobium officinale in water, and wet pulverize after soaking;

[0032] (2) vacuum freeze-drying the dendrobium officinale wet powder after wet crushing;

[0033] (3) the dendrobium officinale powder after vacuum freeze-drying is carried out microwave heat treatment, after heating, quench;

[0034] (4) The cooled dendrobium officinale powder is subjected to wall-breaking treatment.

[0035] The crushing speed is 700r / min, and the crushing time is 15min; in the vacuum freeze-drying step, the thickness of the material is 1mm, the freeze-drying temperature is -15°C, and the vacuum degree of freeze-drying is 15Pa; the microwave heating time is 40min; , the breaking temperature is 30° C., and the breaking time is 70 minutes; an ultrasonic treatment step is also included before the breaking treatment step; the ultrasonic treatment time is 60 minutes;

Embodiment 3

[0037] The process steps and parameters of the preparation method of Example 1 are basically the same, the difference is that the fresh Dendrobium candidum is not soaked in water.

Abstract

The present application discloses a preparation method of fresh Dendrobium candidum freeze-dried broken wall superfine powder, (1) soak fresh Dendrobium candidum in water, and carry out wet crushing after soaking; (2) wet powder of Dendrobium candidum after wet crushing vacuum freeze-drying; (3) subjecting the dried Dendrobium officinale powder to microwave heating treatment, and quenching after heating; (4) carrying out wall-breaking treatment on the cooled Dendrobium officinale powder. Through the preparation method of the invention, the disadvantages of high loss, easy agglomeration, unstable fineness and the like of the traditional dispersing process are solved. And through the preparation method of the freeze-dried broken wall superfine powder, the cell tissue of Dendrobium candidum is obviously changed, and the cell wall is broken, so that the effective components of Dendrobium candidum are better exposed, and its biological utilization value is greatly improved.

Description

technical field [0001] The application relates to the deep processing of medicinal materials, in particular to a method for preparing fresh dendrobium officinale freeze-dried broken-wall superfine powder. Background technique [0002] The processed dry product of Dendrobium candidum is called Tiepi Fengdou, and its medicinal ingredients are mainly dendrobium polysaccharides, dendrobine and total amino acids. It can improve human immunity, enhance memory, nourish the five viscera, resist aging, inhibit tumors, improve diabetes symptoms, resist hypoxia, and have significant effects on radiotherapy and chemotherapy, night life, and excessive smoking and drinking. [0003] At present, the processing of Dendrobium candidum powder often adopts small-scale grinding machines to grind powder. 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 Dendrobium candidum, serious loss directly makes...
